What Expenses Can I Claim as a UK Freelancer?

Claiming allowable expenses is one of the most straightforward ways to reduce your tax bill as a freelancer. Expenses lower your taxable profit, which means less income tax and less Class 4 National Insurance. But HMRC has clear rules about what qualifies — and getting it wrong can cause problems at a self-assessment enquiry.

The “wholly and exclusively” rule

Every business expense you claim must pass HMRC's fundamental test: it must be incurred wholly and exclusively for the purposes of your trade. This sounds simple, but it has teeth.

If a cost has anyprivate purpose, it fails the test in full — unless you can apportion it. For example, if you use your phone 60% for business and 40% personally, you can claim 60% of the cost. But if you buy a smart suit “for client meetings” that you also wear socially, HMRC will disallow it entirely because the clothing has a dual purpose.

The key question to ask yourself before claiming anything: would you have bought this if you were not running your business?

Office costs

If you work from a rented office, hot-desk at a co-working space, or use a commercial premises, the costs are straightforwardly allowable:

• Rent and service charges
• Business rates (if you pay them)
• Utilities — electricity, water, heating — for the workspace
• Cleaning and maintenance
• Stationery, printer ink and paper
• Postage and courier charges
• Small office supplies (pens, folders, envelopes)

For home-based freelancers, see the Home office expenses section below — different rules apply.

Equipment and technology

Equipment you buy for your business is generally claimable in full in the year of purchase under Annual Investment Allowance (AIA), which covers up to £1 million of qualifying plant and machinery per year — far more than any freelancer will spend. Common examples:

• Laptop or desktop computer
• Monitor, keyboard, mouse, webcam, headset
• External hard drives and USB storage
• Tablet or iPad (if used for work)
• Camera or photography equipment (for photographers, videographers)
• Specialist tools or instruments relevant to your trade

If the equipment has any personal use, you can still claim, but you should reduce the claim proportionally. HMRC accepts reasonable apportionment — a laptop used 80% for work and 20% for personal use can have 80% of its cost claimed.

Software and subscriptions

Software subscriptions used for your business are fully allowable operating expenses:

• Adobe Creative Cloud, Figma, Sketch
• Microsoft 365 or Google Workspace
• Project management tools (Notion, Asana, Linear)
• Accounting software (Xero, FreeAgent, QuickBooks)
• Cloud storage (Dropbox, Google Drive)
• 3docs and other invoicing tools
• Domain name registration and web hosting

Travel and transport

Business travel is allowable — but commuting is not. If you work primarily from home and travel to a client's office for a meeting, that journey is business travel. If you rent a fixed desk in a co-working space and travel there every day, HMRC may treat that as commuting.

Mileage allowance

If you use your own car for business journeys, you can claim HMRC's Approved Mileage Allowance Payments (AMAP) instead of actual fuel costs:

• 45p per mile for the first 10,000 miles in a tax year
• 25p per mile for every mile over 10,000
• 24p per mile for motorcycles
• 20p per mile for bicycles

Keep a mileage log with dates, destinations and business reasons. HMRC may ask to see it.

Public transport and taxis

Trains, buses, the Tube, and taxis taken for business purposes are all fully allowable. Keep your tickets or receipts, or use your bank statement as evidence.

Parking and tolls

Business parking fees and road tolls are allowable. Parking fines are not — fines are never a tax-deductible expense.

Overnight stays

If you need to stay overnight for a client project or conference, reasonable hotel costs are allowable. HMRC publishes benchmark subsistence rates for meals during overnight stays if you do not keep receipts, but it is safer to keep them.

Training and professional development

Training costs are allowable if they improve or update existing skills relevant to your current trade. Examples:

• Online courses on platforms like Udemy, Coursera, LinkedIn Learning
• Books, e-books and journals directly related to your work
• Conferences, workshops and seminars in your field
• Technical certifications (AWS, Google Analytics, etc.)

The key limitation: training that helps you set up a completely new business or trade is not allowable. A graphic designer taking a Photoshop masterclass — allowable. The same designer taking a first-aid course to become a paramedic — not allowable.

Marketing and advertising

Costs to promote your freelance business are fully allowable:

• Google Ads, Meta Ads, LinkedIn ads
• Website design, development and maintenance
• SEO tools and services
• Business cards and printed marketing materials
• Photography for your portfolio or website
• PR or press release services
• Listing fees on freelance platforms (Toptal, PeoplePerHour, etc.)

Professional fees and memberships

Fees paid to professionals for services that keep your business running are allowable:

• Accountant fees — for preparing your self-assessment return or business accounts
• Solicitor fees — for drafting contracts relevant to your business
• Professional indemnity insurance — standard for most freelancers
• Public liability insurance
• Contents insurance — for business equipment only (or the business portion)
• Professional body memberships — e.g. AIGA, CIPD, BCS, CIPR — if membership is relevant to your trade
• Bank charges on your business account

Bank interest on a business loan or business credit card used entirely for the business is also allowable. Personal loan interest is not.

Home office expenses

If you work from home, you can claim a proportion of your household costs — but only the fraction attributable to your business use. HMRC offers two methods:

Simplified flat rate (easiest)

HMRC publishes monthly flat rates based on how many hours per month you work from home:

• 25–50 hours/month: £10/month
• 51–100 hours/month: £18/month
• 101+ hours/month: £26/month

This covers electricity, heat, water and broadband for the workspace. You cannot claim mortgage interest, rent, or council tax under this method. For most full-time freelancers working from home, this gives a maximum of £312/year — modest but completely hassle-free.

Actual costs method

If your household costs are high, you may get a bigger deduction by calculating the actual proportion attributable to business use. The typical approach:

• Count the number of rooms used exclusively for work (usually just one)
• Divide by the total number of rooms in your home
• Apply that fraction to relevant costs: electricity, gas, broadband, council tax
• Further apportion by the percentage of time the room is used for business

A word of caution: if you dedicate a room exclusively to your business, HMRC may argue it qualifies for Capital Gains Tax relief on the business-use portion when you sell your home. Most advisers recommend keeping some personal use of the room to avoid this.

Phone and internet

If you use your personal mobile and broadband for work, you can claim the business-use proportion. A reasonable estimate of 50% is commonly accepted for a freelancer who also uses these personally, though you should be prepared to justify your figure if asked.

If you have a separate business phone or SIM, you can claim 100% of the cost.

Clothing

This is one of the most misunderstood areas. HMRC's position is clear: you cannot claim clothing as a business expense just because you wear it to work or to meet clients. The test is whether the clothing is unsuitable for everyday wear — not whether you actually wear it every day.

What is claimable:

• Uniforms or workwear with a company logo
• Protective clothing (PPE) — high-visibility vests, hard hats, safety boots for tradespeople
• Costumes for performers, actors, or entertainers

A suit, dress, or smart shoes worn to client meetings is not claimable, even if you only wear it for work. HMRC has won numerous cases on this point.

What you cannot claim

Beyond the clothing point above, there are several other common expenses that freelancers try to claim but cannot:

• Client entertaining — taking a client to lunch, dinner or a sporting event. HMRC explicitly disallows entertaining as a deduction, even if it is purely for business reasons
• Fines and penalties — parking fines, HMRC late filing penalties — none of these are deductible
• Personal expenses — groceries, gym memberships (unless you are a personal trainer), Netflix, haircuts
• Capital losses on investments — personal share trading losses are not a business expense
• Your own wages — as a sole trader you cannot pay yourself a salary as an expense. You simply draw profit
• Pension contributions — these are not a business expense, but they do reduce your overall tax bill. Personal pension contributions get tax relief at your marginal rate

How to record expenses

HMRC requires you to keep records of all your business income and expenses for at least 5 years after the 31 January self-assessment deadline they relate to. In practice, that often means 6–7 years of records.

For each expense you claim, keep:

• A receipt or invoice showing the supplier, date, amount and what was purchased
• Evidence of payment (bank statement or card statement)
• A note of the business purpose, if it is not obvious from the receipt

Digital records are fine — scanning or photographing receipts and storing them in a folder (or an accounting app) satisfies HMRC. You do not need to keep paper originals as long as the digital copy is legible and complete.

Logging expenses as they happen is much easier than trying to reconstruct them at the end of the tax year. Even a simple spreadsheet updated weekly will save you hours in January.
