Freelancer Allowable Expenses 2026: The Complete UK List

The "wholly and exclusively" test

Every freelancer expense rule in the UK comes from one short legal phrase. HMRC will accept a cost as deductible against your trading profit if it was incurred "wholly and exclusively for the purposes of the trade". That phrase sits in section 34 of the Income Tax (Trading and Other Income) Act 2005, and it is the single test that decides whether the receipt in your wallet saves you tax or not.

Wholly means the entire payment relates to the business. Exclusively means it has no private benefit running alongside it. A subscription to your design software is allowable because it has no domestic use. A new pair of jeans is not, even if you wear them only to client meetings, because they also provide warmth and decency. That second test is the one that catches most freelancers out.

Where a cost has a clear, measurable business element and a clear, measurable private element, you can usually claim the business proportion. A phone bill is the classic example. A car bought for mixed use is another. The rule does not stop the deduction, it just narrows it. Where the two elements are blurred or the business slice is incidental, HMRC will refuse the whole thing.

One piece of context worth carrying forward through the rest of this guide: HMRC's enquiry team rarely argues that a category is in principle non-deductible. The arguments we see in practice are about evidence (was the receipt retained?) and proportion (is 90% really business use, or is it closer to 60%?). The categories below are uncontroversial. The numbers you put against them are where the work sits.

Home office expenses

Most UK freelancers work from home for at least part of the week. HMRC accepts that and offers two methods for claiming the cost.

Method 1: simplified flat rate

The simplified expenses regime sets fixed monthly amounts based on hours worked at home:

• 25 to 50 hours a month: £10 a month (£120 a year)
• 51 to 100 hours a month: £18 a month (£216 a year)
• 101 hours or more a month: £26 a month (£312 a year)

The rate covers heating, lighting, electricity and broadband for the work portion. It does not cover rent, mortgage interest or council tax. You add those on top using a proportional calculation if you want them. For a freelancer working from home full-time, £312 a year is usually too low to be the best answer.

Method 2: proportional (actual costs)

The proportional method calculates a genuine business share of household costs. The standard formula uses two ratios:

Business share = (rooms used for work ÷ total rooms in the home) × (hours used for work ÷ total hours per week)

A freelancer using one dedicated room in a five-room home, working 40 hours a week, would claim (1/5) × (40/168) which is around 4.8% of household running costs. Apply that percentage to rent, council tax, gas, electricity, water, insurance, broadband, repairs to the room used, cleaning costs and security.

Take a worked example. One Camden freelance copywriter we onboarded last year rents at £1,800 a month with council tax of £160, utilities of £180 and broadband of £45 (total £2,185 a month or £26,220 a year), and claims roughly 4.8% as the business share. That works out at £1,258 a year, around four times the simplified flat rate. Even at a more conservative 3% allocation, the proportional method beats simplified for full-time home workers in London.

Watch one trap. Claiming a room as 100% business use can create a Capital Gains Tax issue on sale if you ever own the property, because part of the home loses Private Residence Relief. Keep a marginal personal use of the room (storage of personal items, occasional weekend use as a study) and the CGT problem does not arise. Most accountants will reduce the room ratio slightly on purpose for this reason.

Travel and mileage

Business travel is allowable where you are travelling from your normal base to a temporary location for work. The journey from home to a fixed place of work is commuting and is not allowable. Once that distinction is settled, the calculation is mechanical.

For cars and vans, HMRC's Approved Mileage Allowance Payments (AMAP) are the simplest route:

• First 10,000 business miles per tax year: 45p per mile
• Above 10,000 miles: 25p per mile
• Motorcycles: 24p per mile (no cap)
• Bicycles: 20p per mile (no cap)

The rate is meant to cover fuel, insurance, road tax, MOT, servicing, depreciation and capital cost of the vehicle. You either claim AMAP or you itemise actual running costs. You cannot claim both. Once you choose a method for a vehicle, you stay on it for the life of that vehicle.

For freelancers driving 8,000 to 12,000 business miles a year in an older car, AMAP almost always wins. For low-mileage drivers in expensive cars, actual costs sometimes do better, although the record-keeping is heavier.

Keep a mileage log. Date, start postcode, end postcode, business reason, miles. A spreadsheet or any of the dedicated apps work. HMRC asks to see this in enquiries roughly every other case. Without a log, the deduction is the first thing they reduce.

Public transport, taxis, train tickets, flights and accommodation when away from base on business are all allowable as actual cost. Keep the receipts.

Equipment and technology

Computers, phones, cameras, audio equipment, tablets, monitors, desk and chair: all allowable where used for the business. Two routes exist depending on cost and durability.

For lower-value items used up within a tax year (cables, accessories, a budget headset) you simply expense the cost in the year of purchase. For higher-value items expected to last more than a year, you claim through the Annual Investment Allowance (AIA), which gives you a 100% deduction in the year of purchase against your trading profit, up to £1 million. The vast majority of freelancer equipment falls comfortably under that ceiling.

If a piece of equipment has personal use, claim the business proportion. A laptop used 70% for work claims 70% of the cost. The principle echoes the home office rule. Keep notes on how you arrived at the percentage in case HMRC asks.

Mobile phones get a small bonus. Where the phone contract is in the business name and used wholly for business, the full cost is allowable. Where the phone is on a personal contract and used partly for work, claim the business share of calls and tariff. A second SIM or business-only line is the easiest way to remove the proportional argument.

Software and subscriptions

Cloud accounting software (Xero, FreeAgent, QuickBooks), design tools (Adobe Creative Cloud, Figma), code editors with paid licences, project management apps, AI tools, password managers, VPNs and any other subscription used to run the business are all allowable. The test is the same: business use only, or business proportion where mixed.

From April 2026, freelancers (sole traders) with gross income above £50,000 must keep digital records and file quarterly under MTD for Income Tax. The cost of MTD-compatible software is itself an allowable expense, so the move to digital effectively pays for part of the compliance burden through the tax saving on the subscription.

Professional fees, insurance and finance costs

Costs of running the business that are not goods or services to customers but are still wholly business in nature sit in this bucket:

• Accountant fees for preparing accounts, the tax return and giving tax advice
• Solicitor fees for trading matters (not for buying or selling property or capital items)
• Professional indemnity insurance for the work you do
• Public liability insurance for any business carried on with the public
• Business contents and equipment insurance
• Bank charges on a business account, including overdraft interest at commercial rates
• Credit card interest where the card is used for business purchases (business proportion if shared)
• Professional membership fees for bodies on HMRC's approved List 3 (most major chartered and professional bodies are on it)

The professional membership rule catches one or two freelancers a year. Membership of a trade body that is not on List 3 is technically not deductible. If you are paying £500 a year to a body and you cannot find it on HMRC's published list, ask before you claim.

Marketing and client acquisition

Anything you spend to find or keep clients is allowable. That includes:

• Website hosting, domain renewal, design fees, paid platform subscriptions
• Paid advertising (Google, Meta, LinkedIn, sponsored content)
• Print marketing (business cards, flyers, branded items)
• Photography for the website or for marketing assets
• Networking events (cost of attendance, including reasonable travel)
• CRM and email marketing tools
• Branding work (logo design, brand book, copywriting)

One distinction matters here. Costs of taking a client out for lunch or buying gifts are classified as client entertainment and are not tax deductible, no matter how clearly business-related. The cost still goes through the business, but it adds back to taxable profit at year end. The same rule applies to limited company directors. Record it for visibility, but do not expect a tax saving on it.

Training and continuing professional development

Training costs that maintain or update existing skills are allowable. Training costs that introduce a new skill or a new line of business are not, because HMRC sees them as capital investment in earning capacity rather than running cost.

A freelance copywriter doing a one-day refresher on SEO best practice claims it as an allowable expense. The same freelancer doing a year-long Diploma in Coding to add a developer service does not, even though both relate to the work they do for clients. The line is "are you maintaining what you already do" versus "are you learning to do something new".

Books, online courses, conference tickets, professional subscriptions to industry publications, mentoring and coaching all sit under training where they meet the existing-skills test.

Travel subsistence and the home office trap

Subsistence (food and drink) while at your normal place of work is not allowable. That includes lunches at home, takeaways at your home office and coffees from the local café. HMRC's view is that you must eat anyway, so the cost is not "additional" because of the business.

Travel-based subsistence is treated differently. Reasonable food costs at a temporary client site, on a business trip out of London, or while staying overnight away from home are allowable. Hotel costs on overnight business travel are allowable in full, including breakfast bundled into the room rate.

For digital nomads or freelancers without a fixed base, the position is harder. Where home is genuinely your normal base and you are away from it, the rules above apply. Where you travel constantly and have no fixed base, HMRC may argue that everywhere is your normal place of work, so nothing qualifies as subsistence away from base. Speak to a chartered accountant before claiming heavy travel subsistence as a roaming freelancer.

What freelancers cannot claim (the rejected list)

Knowing the no-list is as valuable as knowing the yes-list. The categories below are routinely claimed by new freelancers and routinely rejected on enquiry:

• Ordinary clothing (suits, shoes, casualwear, even for client meetings)
• Gym memberships, dental work and most health costs (specific exceptions for safety-critical roles)
• Childcare while you work (specific tax-free childcare schemes exist separately)
• Fines and penalties (parking, speeding, late filing penalties to HMRC, regulatory fines)
• Personal pension contributions made by you (these get separate tax relief through your tax return, not as a business expense)
• Capital costs of buying a property, lease premiums and most capital items (some go through capital allowances)
• Personal entertainment (Netflix, Spotify, gym, golf)
• Charitable donations made personally (Gift Aid claims them elsewhere)
• Drawings (money you take out of the business for personal use is not an expense; it is post-tax profit)

Where the expenses actually go (a typical freelancer breakdown)

To make the categories concrete, here is the typical pattern we see for a London freelancer earning around £60,000 net of expenses, claiming roughly £12,000 of allowable costs in total.

The split is approximate and varies by trade. A freelance photographer carries far more equipment. A freelance bookkeeper carries almost none. A freelance management consultant carries more travel than the average. The point of the chart is to anchor the conversation in concrete numbers rather than abstract categories.

The tax saving on £12,000 of expenses

Claiming £12,000 of expenses reduces your taxable profit by £12,000. The cash saving depends on your marginal tax band.

A freelancer with profits sitting comfortably in the basic rate band saves 20% Income Tax plus 6% Class 4 NIC on the deducted amount, which is 26% combined. On £12,000 that is roughly £3,120 of tax and NIC kept rather than paid.

Higher up the income scale, a freelancer in the £50,271 to £125,140 band saves 40% Income Tax plus 2% Class 4 NIC on the deducted amount, which is 42% combined. On £12,000 that is roughly £5,040 of tax and NIC kept rather than paid.

Those numbers are why expense claims matter so much. The same £12,000 of receipts is worth nearly £2,000 more in the hand to a higher-rate freelancer than to a basic-rate one. Losing receipts or under-claiming categories is one of the cheapest mistakes new freelancers make.

What this means for you

If you have been freelancing for less than a year, three actions will get you 80% of the benefit before the next 31 January deadline:

1. Open a dedicated business bank account. Free Starling or Tide accounts work fine. Run every business inflow and outflow through it. The reconciliation problem goes away.
2. Move to digital bookkeeping. Xero, FreeAgent or QuickBooks will pull bank transactions in, categorise them automatically and create a year-end position you can hand to an accountant in 10 minutes. It also keeps you ready for MTD for Income Tax from April 2026.
3. Photograph every receipt as you go. Most bookkeeping apps have a snap-and-attach feature. Five seconds per receipt. The shoebox at year end disappears entirely.

If you are already established and just want to make sure you are claiming the right amount, the categories above are the audit. Walk through each one. If you have not claimed against a category in the last 12 months and you know the cost was incurred, the saving sits there waiting to be picked up. A 30-minute review usually finds two or three categories that have been overlooked.

From April 2026 the rules harden. MTD for Income Tax is mandatory for sole traders and landlords with gross income above £50,000. Quarterly digital filing replaces the annual return for that group. Five filings a year instead of one. The expense rules above do not change, but the speed at which you need to capture them does. Manual bookkeeping at year end is no longer a workable option above the threshold.
