Categories of Expenditures: Business Expense List 2026

Business expenses can quickly become messy when everything from payroll and software to travel and office costs is being coded differently. A clear set of expense categories makes it easier to track spending, report accurately, manage budgets, and understand what is and isn’t tax-deductible.

This guide breaks down the main categories of business expenditure UK and European finance teams should know, with practical examples and guidance on how to structure them.

Key takeaways

Categories of expenditures organise business costs for accounting, reporting, and tax purposes. These five rules keep the structure useful:

• Categorise every cost by the nature of the purchase, not the payment method or the person who paid.

• Separate capital purchases from revenue costs when coding them, because the two follow different tax routes.

• Give non-deductible items, such as client entertaining, their own account so the add-back is a filter rather than a hunt.

• Match your category structure to the profit and loss format used in your statutory accounts.

• Capture the receipt and VAT at the point of spend, then assign the category so month-end becomes a review task.

What are business expense categories and why do they matter?

Categories of expenditures are the standing accounts a business uses to group every cost it incurs according to the nature of the purchase.

The main groups covered in this article are:

• Payroll

• Rent

• Utilities

• Software subscriptions

• Advertising and marketing

• Travel and entertainment

• Professional services

• Equipment

• Employee perks

Without clear categories, miscoded transactions create extra work in financial reporting and tax computations.

For growing businesses, the categories you choose determine how much month-end work sits with your accountants and how many lines they need to add back when preparing the corporation tax return.

The pressure sits on a handful of major cost lines. In the Federation of Small Businesses' Q2 2026 index:

• 58% of UK small firms named taxation as a driver of cost increases.

• 55% named fuel.

• 54% named utilities.

• 53% named labour.

Each of these maps to a category in the list below, and each follows a different tax rule. If your chart of accounts blurs them together, you cannot tell which line moved.

This guide lists the categories most UK and European companies with 50 to 500 employees carry, explains which are normally deductible, and shows how to set up categorisation so the bookkeeping queue stays clean throughout the month.

Important: This is general guidance for UK finance teams, not tax advice. VAT treatment depends on your specific circumstances. Consult a qualified tax adviser before making decisions based on the rules covered here.

Business expense categories list

The list below covers the categories of expenditures most UK and European mid-market companies keep in their chart of accounts.

Each entry gives the usual accounting treatment and the tax point that matters most when coding the transaction.

Payroll

Payroll covers:

• Salaries

• Bonuses

• Employer pension contributions

• Employer National Insurance

• Agency fees

• Recruitment fees

HMRC treats employee salaries, bonuses, pensions, employer NIC, agency fees, and subcontractor costs as allowable staff costs for a trade.

Respondents cited labour more frequently than any other cost driver in EY's Entrepreneurship Barometer 2026.

The survey covered 1,009 SME and mid-market entrepreneurs across 14 European countries in February and March 2026. The main cost drivers were:

• Labour costs: 87%

• Technology upgrades: 66%

When one category faces this level of pressure, splitting direct labour, which may belong in cost of sales, from administrative payroll helps show whether the change comes from delivery headcount or overhead.

According to HMRC's published rates and thresholds for 2025/26, employer secondary Class 1 NIC is 15% above a £5,000 annual secondary threshold, with a £10,500 Employment Allowance available to offset it.

A later tax year may carry different figures, so check the rates for whichever year you are budgeting. HMRC guidance is the natural first stop before finalising your numbers, since thresholds change each April.

Rent

Rent covers:

• Office leases

• Co-working memberships

• Business rates

• Service charges

• Equipment leases

HMRC lists rent, business rates, utilities, property insurance, security, and repairs as allowable business premises costs. Lease payments are also allowable financial costs.

Payments to buy or improve a property count as capital expenditure and follow the capital allowances route under equipment and furniture.

A repair keeps premises in working order and remains in this category. An extension or fit-out that adds something new does not.

If your lease bundles rates and service charges into one invoice, ask for the split so business rates can sit in the relevant tax account rather than inflating rent.

Utilities

Utilities cover:

• Electricity

• Gas

• Water

• Telephone

• Business internet

These are allowable as premises costs. Where a cost includes private use, only the identifiable business proportion is deductible.

The Federation of Small Businesses' Q2 2026 survey placed utilities among the top cost drivers. This is one category where a single utilities account can hide useful information.

Splitting energy from telecoms costs almost nothing at coding time and shows which supplier moved when the total changes.

Software subscriptions

Recurring software-as-a-service fees are revenue expenditure, not capital expenditure, and are expensed over the subscription period.

The IFRS Interpretations Committee decided in March 2019 that a contract giving you only a right to access a supplier's software is a service contract. You receive no intangible asset.

An upfront fee covering future periods, sometimes described as deferred revenue expenditure, sits on the balance sheet as a prepayment and is released as the service is received. It does not create a software asset.

HMRC takes the same view for shorter-lived software. Its Business Income Manual at BIM35810 states:

You should not contend that software with an expected useful life of less than two years is capital.

Subscriptions are also the category most prone to:

• Duplicate subscriptions

• Unused seats

• Unapproved renewals

• Suppliers being paid from shared cards

The free guide to managing subscriptions covers the audit process. You can also learn how to track SaaS subscriptions in more detail.

One structural fix is to pay each tool with its own virtual card, so the renewal lands against a named supplier and category rather than on a shared card statement.

Spendesk's software subscription workflow issues subscription virtual cards for this purpose.

Advertising and marketing

Under HMRC's allowable expenses guidance, advertising and marketing costs are normally allowable for UK tax where they are incurred wholly and exclusively for the purposes of the trade.

The position can vary for specific costs, so check current HMRC guidance or speak to your adviser if you are unsure.

The category covers:

• Paid media

• Agency retainers

• Events

• Sponsorships

• Public relations

• Content production

• Marketing software

This is often the hardest category to hold to budget, perhaps alongside travel, because spend arrives from many small suppliers and across several cards.

Splitting media spend from agency fees, then separating both from tooling, gives budget owners a variance they can act on.

A fuller breakdown of marketing expenses shows how to structure the sub-accounts.

Travel and entertainment

Travel and entertainment should be two separate accounts because they follow different tax rules in the UK.

Business travel covers:

• Air fares

• Hotels

• Meals on overnight trips

• Trains

• Taxis

• Hire cars

• Other qualifying ground transportation

Where travel qualifies as business travel and is incurred wholly and exclusively for the trade, it is normally allowable under HMRC business travel guidance.

Under Corporation Tax Act 2009 section 1298, client entertaining is denied a deduction even where it would otherwise pass the wholly and exclusively test. It is added back in the tax computation regardless of business purpose, as confirmed in BIM45000.

Additional travel rules

Three further rules shape the travel account:

• Ordinary commuting from home to a permanent workplace does not qualify.

• A workplace is treated as permanent where the employee attends it during a period of continuous work lasting, or likely to last, more than 24 months and spends 40% or more of their working time there.

• HMRC's benchmark subsistence rates for employees are £5 for a five-hour journey, £10 for ten hours, and £25 for 15 hours or more where travel is ongoing at 8pm.

These rates remained unchanged for 2025/26 and 2026/27. They apply only where travel qualifies and the employee has actually incurred a meal cost.

HMRC sets no benchmark rate for overnight subsistence. Confirm each rate against current HMRC guidance before writing it into policy.

Servers and website maintenance

Hosting, domains, content delivery, monitoring, and maintenance contracts are recurring service fees. They belong with software subscriptions as revenue costs.

You do not own the supplier's infrastructure, so you expense the fee as you receive the service.

A website build or major redesign is different.

HMRC's guidance at BIM35805 determines the character of lump-sum software spend by:

The role in economic terms that the software plays in the business.

For companies, software rights usually fall within the intangible fixed assets rules in Corporation Tax Act 2009 Part 8, where the tax treatment follows the accounting treatment.

That makes the accounting decision the tax decision, so agree it with your auditor or adviser before the project starts, rather than at year-end.

Tax

The tax category holds taxes that are themselves business costs, chiefly:

• Employer National Insurance

• Business rates

HMRC treats both as allowable.

Keep these separate from the tax charge on profit, which is not an expense of the trade.

Fines and penalties belong in their own account within this category.

BIM38515 confirms that fines and penalties are generally added back in the tax computation.

A parking fine coded to travel or a late-filing penalty coded to professional fees becomes an adjustment someone has to hunt for later.

Recording VAT separately from the net cost of each expense keeps the VAT return and the profit and loss account from disagreeing.

Business insurance

Business insurance premiums are generally allowable. This includes:

• Professional indemnity

• Public liability

• Employer's liability

• Property insurance

• Cyber cover

HMRC lists professional indemnity and business insurance among allowable financial costs, vehicle insurance under travel, and property insurance under premises.

A policy that protects an owner's personal position rather than the trade can fail the wholly and exclusively test.

Check the beneficiary and purpose of key-person and life cover with your adviser before coding it here.

For younger companies deciding what to buy first, the guide to startup insurance sets out the usual order.

Consultants and professional services

Fees to accountants, solicitors, consultants, and fractional executives can qualify as allowable professional costs when the business incurs them wholly and exclusively for the trade and they are revenue rather than capital in nature.

Code them by the nature of the service, not by the supplier's employment status:

• A freelance accountant's fee sits here.

• A freelance developer's fee sits in contract labour or cost of sales.

Two exceptions catch people out.

HMRC's BIM38525 guidance requires accountants to add back legal costs of a capital nature, such as fees on acquiring an asset. Keep them separate from routine legal and advisory fees.

Where you engage individuals through their own companies, the off-payroll working rules may make you responsible for determining their status.

The rules apply to:

• All public-sector clients

• Medium and large private-sector clients

• Medium and large voluntary-sector clients

Small private-sector clients are exempt.

Whether the rules apply to you depends on your size and structure. From 6 April 2025, HMRC's current size test requires you to meet two of three thresholds to fall within scope:

• Annual turnover above £15 million

• Balance sheet total above £7.5 million

• More than 50 employees

Where the rules apply, you must issue a status determination statement setting out whether the worker would be an employee if directly engaged, together with the reasons.

Because these thresholds and rules can change, confirm the current position against HMRC's employment status manual.

Outsourced CFOs are one of the more common engagements in this category for scaling companies.

Training and learning

Business-related training is an allowable cost, and HMRC lists it alongside staff costs.

The category covers:

• Courses

• Certifications

• Conference tickets

• Learning platform subscriptions

• Books

Travel to a conference belongs in travel, while the ticket belongs here.

Keeping the two separate means the training budget reflects what was learned, while the travel budget reflects how people moved.

Equipment and furniture

Laptops, monitors, desks, machinery, and fit-out count as capital expenditure.

They go on the balance sheet. Accountants add depreciation back in the tax computation, and the business claims relief through capital allowances instead.

HMRC's BIM42060 guidance confirms that businesses deduct capital expenditure as capital allowances rather than as a revenue expense.

Main UK capital allowance reliefs

The following figures reflect the position as of September 2026. Eligibility conditions and rates can change, so check each one against HMRC's current capital allowances guidance before using them to set policy, code transactions, or model relief.

The Annual Investment Allowance gives a 100% first-year allowance on most plant and machinery, excluding cars, up to £1,000,000 per accounting period.

Full expensing applies to companies only. It is a 100% first-year allowance on new and unused main-rate plant and machinery, excluding cars and leased assets. Finance Act 2023 made it permanent.

As of September 2026, the Autumn Budget 2025 reduced the main pool writing-down allowance from 18% to 14%.

The cut took effect:

• 1 April 2026 for corporation tax

• 6 April 2026 for income tax

Accounting periods straddling those dates use a hybrid rate. The special-rate pool writing-down allowance remains at 6%.

The Autumn Budget 2025 also introduced a 40% first-year allowance from 1 January 2026. It applies to unincorporated businesses and leased assets.

Check each relief against current capital allowances guidance before modelling a purchase.

Businesses sometimes fund larger purchases through asset-based financing or inventory financing rather than cash.

The financing route does not change the category. The asset is still capital.

Office supplies

Stationery, printing, postage, and consumables are allowable office costs.

Small equipment that falls below your capitalisation threshold also lands here rather than on the fixed asset register.

Set that threshold in writing.

Without one, a keyboard gets capitalised by one bookkeeper and expensed by another. The fixed asset register then fills with items that will never be tracked.

This category is also where petty cash tends to leak because small purchases arrive without receipts and are coded to office by default.

Hybrid working setup

Home-working costs cover equipment bought for a home office, including:

• Monitors

• Chairs

• Home-working allowances

• Co-working day passes

Tax treatment depends on who owns the equipment, whether the employer reimburses it, and whether the arrangement is contractual.

Agree the policy with your adviser before the first purchase.

Sole traders working 25 or more hours a month from home can use HMRC's simplified flat rates:

• £10 a month for 25 to 50 hours

• £18 for 51 to 100 hours

• £26 for 101 hours or more

Phone and internet can be claimed separately on an apportioned basis.

These are HMRC's published simplified expenses rates at the time of writing. Check the GOV.UK guidance directly before building them into a claim or policy.

Those rates do not apply to companies reimbursing employees.

Travel from home to a permanent workplace is generally treated as ordinary commuting, whichever days the employee is in the office. The outcome depends on whether the workplace is permanent or temporary.

Remote staff paying personally and claiming reimbursement is where receipts often go missing.

Giving them their own employee debit cards with a home-office limit moves the receipt request to the moment of purchase.

Fuel and mileage

Employers can pay employees who use their own car for business a mileage allowance that is generally free of tax and National Insurance where the conditions are met.

This applies up to HMRC's approved mileage rates.

From 6 April 2026, the approved mileage allowance payment rate for cars and vans rose to 55p per mile for the first 10,000 business miles.

For 2026/27:

• First 10,000 business miles: 55p per mile

• Mileage above 10,000 miles: 25p per mile

• Motorcycles: 24p per mile

The 45p car and van rate applied for 2025/26, so historic claims use that earlier figure.

These rates are subject to change. Verify the approved mileage rate for the specific tax year against the GOV.UK guidance before publishing your policy.

Fuel bought on a company card for a company vehicle is a different transaction and needs its own account.

HMRC publishes separate advisory fuel rates for reimbursing private mileage in company cars. See HMRC's fuel rates for the United Kingdom.

The rules on how employees claim a mileage allowance cover the required paperwork.

A mileage log needs:

• Date

• Journey

• Purpose

• Distance

The free HMRC mileage calculator applies the current rates to a logged distance.

Employee perks

Staff events, wellbeing spend, gifts, benefits, and healthcare provision sit in employee perks, separate from client entertaining.

HMRC's BIM45033 guidance treats staff entertaining as allowable where it is wholly and exclusively for the trade and not incidental to entertaining customers.

Healthcare benefits are generally regarded as reportable benefits in kind for the employee, even where the employer's cost is an allowable staff expense. The precise reporting position can depend on the arrangement and how it is structured.

Confirm the position against current HMRC employment income guidance or with your adviser before filing.

Annual function exemption

The annual function exemption is the rule most finance teams need.

Under ITEPA 2003 section 264, where an annual party or similar function is available generally to employees, or generally to employees at one location, no benefit-in-kind charge should arise provided the cost per head, including VAT and any transport or accommodation, does not exceed £150.

Where several annual functions exceed £150 in aggregate, HMRC's approach is to treat the functions that make the best use of the £150 allowance as exempt and the remainder as taxable in full.

A one-off event does not qualify.

HMRC has announced a phased introduction of mandatory payrolling of benefits in kind from 6 April 2027, although that timetable remains subject to change.

Confirm both points against current HMRC employment income guidance before relying on them.

When are expenses tax-deductible?

In the UK, an expense is generally deductible where the business incurs it wholly and exclusively for the purposes of the trade and no specific rule disallows it.

The outcome depends on the facts of the particular cost.

Assigning a cost to a category in your accounts is a coding decision. It does not by itself determine whether the expense is tax-deductible.

Deductibility still depends on:

• Whether the wholly and exclusively test is satisfied

• Whether a specific disallowing rule applies

• Whether the cost is revenue or capital in nature

• Whether the relevant evidence has been retained

For sole traders and partnerships, the test sits in Income Tax (Trading and Other Income) Act 2005 section 34.

For companies, it sits in Corporation Tax Act 2009 section 54.

HMRC's interpretation at BIM37050 is that the trade purpose must be the sole purpose at the time the money is spent.

An incidental private benefit does not necessarily break the test. Where a mixed cost has an identifiable business proportion, that proportion may be deductible.

Where no objective yardstick separates the business and private elements, none of it may be deductible.

Debt repayment is not an expense

Debt repayment sits outside this test.

Paying back the capital element of a loan does not consume a cost in the period. It settles a balance-sheet liability instead.

It is therefore not a business expense and has no place in an expense category, regardless of what the borrowing was for.

Interest and related finance charges are a separate question. Where the loan was taken out for the purposes of the trade, those charges can be allowable financing costs, although the outcome depends on the facts of the arrangement.

Confirm your position with your adviser before treating financing costs as deductible.

Common tax add-backs

The second half of the test is the list of items that tax rules disallow even when the purpose is entirely commercial.

Each row requires a category decision when coding the transaction.

If client entertaining, penalties, and capital legal fees each have their own account, the tax computation starts from a filtered ledger rather than a line-by-line review of meals and professional fees.

That is the difference between a two-hour adjustment exercise and a two-day one. The decision is made in the chart of accounts, months before the return is due.

The rules above reflect the position as of September 2026. Confirm them with your adviser before relying on any single figure.

Why business expense categories matter

Finance teams use expense categories to control whether:

• The tax computation is right

• Statutory accounts present costs in the legally required format

• Budget owners can act on variances quickly

• The month-end close is based on review rather than reconstruction

The cost environment makes the third outcome particularly urgent.

The ACCA and IMA Q4 2025 survey found that:

• Four-fifths of UK respondents reported increased operating costs.

• Three-quarters of Western European respondents reported increased operating costs.

A finance team facing that level of pressure needs to know within days whether the rise sits in a major category such as payroll or energy.

A single overheads account cannot answer that question.

Categories also become an important factor in times of crisis.

When the business needs to cut, a well-structured ledger can separate:

• Committed spend, such as rent, payroll, and insurance

• Discretionary costs, such as marketing, travel, and employee perks

• Variable expenses, such as fuel, media spend, and usage-based software

• Periodic expenses, such as insurance renewals and annual licences

Leadership can then cut where it hurts least, while budget owners can distinguish genuine overspend from seasonal noise.

In ordinary months, the same structure helps you keep costs under control.

A budget owner who sees marketing tooling at 120% of budget on the 10th can act. A budget owner who sees overheads up on the 31st cannot.

How to categorise expenses for a small business

Start from the profit and loss format used in your statutory accounts. Then build the chart of accounts so someone who is not an accountant can code every transaction once at the point of spend.

The following six steps provide a practical framework.

1. Choose nature or function

UK company accounts follow one of two formats under the Schedule 1 rules.

Format 1 presents costs through:

• Cost of sales

• Distribution costs

• Administrative expenses

Format 2 presents costs by nature, including:

• Raw materials

• Staff costs

• Depreciation

• Other charges

Micro-entities under FRS 105 may use only Format 2.

IFRS reporters should note that IFRS 18 permits nature, function, or a mixture from 1 January 2027, with a single note disclosing depreciation and amortisation alongside employee benefits where function is used.

2. Number the chart in blocks

Sage's UK default places direct expenses in the 5000 to 5999 range and overheads in the 6000 to 9999 range. Most systems follow a similar pattern, while Xero leaves numbering to you.

Whatever scheme you use, leave gaps so new sub-accounts can be added without renumbering.

3. Write down the capitalisation threshold

Pick the value above which a purchase becomes a fixed asset and publish it to everyone who codes transactions.

This is the single rule that stops equipment and office supplies bleeding into each other.

4. Give every add-back its own account

Client entertaining, fines and penalties, and capital legal costs need separate codes.

This ensures the tax adjustment is a report rather than a search.

5. Set coding rules for recurring suppliers

Your hosting provider should always be coded to servers. Your payroll bureau should always be coded to professional fees.

Deterministic rules based on suppliers and cards remove the judgement call from hundreds of transactions each month.

6. Capture the receipt and VAT at the point of spend

A category assigned at purchase, with the receipt attached, needs review at month-end rather than reconstruction.

This guide to collecting receipts explains how further card spend can be held until the receipt arrives.

Steps one to four are decisions you make once. Steps five and six are where the day-to-day effort goes.

For a two-person bookkeeping team processing more than 200 transactions a month, rule-based coding is what turns a type-and-hope job into review-and-confirm.

This is where a spend management platform earns its place.

How can I help?

Spendesk is an all-in-one spend management platform consolidating:

• Company cards

• Expense management

• Accounts payable

• Procurement

• Budgeting

For the categorisation problem described in this article, that consolidation lets finance attach the category, receipt, and VAT breakdown to a transaction when the money moves.

Finance does not need to reconstruct the record from a card statement three weeks later.

The platform's bookkeeping automation combines deterministic rules, such as coding a hosting supplier to servers, with machine-learning-based suggestions for the rest.

The accountant reviews and confirms each prepared field rather than keying it manually.

Optical character recognition through Marvin reads the receipt or invoice and extracts supplier details and VAT amounts, helping keep the tax account clean.

From there, the finance team can push exports as mapped journal entries to native accounting integrations, including Xero, NetSuite, Sage 100, and DATEV, where supported by the configuration.

Before relying on a specific connection, confirm the current integration catalogue and mapping for your accounting system.

The cost pressures in the FSB and EY surveys will not ease simply because your ledger is tidy.

However, when taxation, fuel, utilities, and labour each sit in their own account, and staff code transactions on the day of purchase, finance can see which category moved while there is still time to respond.

Learn how Spendesk approaches bookkeeping automation when finance needs prepared fields without giving up review.

The Get a free tour page also illustrates how coding rules, receipt capture, and accounting export fit together.

Frequently asked questions

These answers cover the definition of categories of expenditures, SaaS configuration costs, pre-trading expenses, entity differences, and chart-of-accounts reviews.

What does “categories of expenditures” mean in accounting?

Categories of expenditures are the accounts into which a business sorts its costs, such as payroll, rent, software subscriptions, or travel.

They allow the same ledger to support:

• Financial statements

• Budgets

• Management reporting

• Tax returns

In UK accounts, categories follow either a nature-based or function-based presentation. Each category may carry a different tax treatment.

Are software configuration and customisation costs an asset under IFRS?

Usually not.

The IFRS Interpretations Committee's April 2021 decision concluded that in most software-as-a-service arrangements, the customer does not control the underlying software.

The customer therefore expenses configuration and customisation costs:

• When the supplier performs a distinct service

• Or over the contract term when the service is not distinct

A separate code controlled by the customer may qualify as an intangible asset under IAS 38. The answer therefore depends on the contract terms.

Can you claim expenses incurred before the company started trading?

Yes, within limits.

Corporation Tax Act 2009 section 61 treats qualifying revenue expenses incurred up to seven years before trading begins as incurred on the first day of trading.

Section 57 of the 2005 Act does the same for sole traders.

In both cases, relief applies only where:

• The cost satisfies the wholly and exclusively test.

• The cost would have been deductible after trading began.

Capital expenditure does not qualify under that rule and follows separate capital allowances provisions.

Pre-registration VAT recovery has its own time limits, so take advice on the specific items.

Do sole traders and companies use the same expense categories?

The categories are broadly the same, but the statutory test and accounts format differ.

Sole traders:

• Apply the wholly and exclusively test under the Income Tax (Trading and Other Income) Act 2005.

• May use HMRC simplified flat rates for vehicles and working from home.

Companies:

• Apply the Corporation Tax Act 2009.

• Cannot use those flat rates.

• Must present accounts in one of the Companies Act formats.

Micro-entities reporting under FRS 105 are further restricted to the nature-based format.

How often should you review your chart of accounts?

Review it at least once a year, ideally before setting the budget, and whenever a new type of spend appears.

Review each account for:

• Transaction volume

• Tax purpose

• Budget ownership

• Mapping to statutory accounts

• Recurring supplier rules

An account with two transactions a year may be better treated as a sub-account or consolidated with another category.

Changes in the Autumn Budget 2025 to capital allowance rates or benefits-in-kind reporting are also a good prompt to check that affected categories remain separated correctly.
