What Expenses Can UK Sole Traders Claim?

Running your own business as a sole trader gives you freedom, but it also means you are responsible for tracking income, expenses, and tax. One of the biggest mistakes many UK sole traders make is not claiming all the business expenses they are allowed to claim.

HMRC lets sole traders deduct allowable business expenses from their income before working out taxable profit. In simple words, the more genuine business costs you record correctly, the more accurate your tax bill becomes.

This is where tools like Taxara can help sole traders keep things organised without relying on messy spreadsheets or lost paper receipts.

Before we go deeper, remember the basic HMRC rule: an expense must be for business purposes. If something is used for both personal and business reasons, you can usually claim only the business part.

What Counts as an Allowable Business Expense?

An allowable business expense is a cost you pay because of your business. HMRC lists common self-employed expenses such as office costs, travel costs, clothing expenses, staff costs, stock, financial costs, business premises costs, advertising, and training.

For example, if you earn £40,000 in a tax year and have £8,000 of allowable business expenses, your taxable profit may be reduced to £32,000.

That does not mean HMRC gives you £8,000 back. It means your tax is calculated on a lower profit figure.

Office, Phone, and Equipment Costs

Most sole traders have basic office costs. These can include stationery, postage, printer ink, software subscriptions, phone bills, and internet costs.

If you use something only for business, the claim is simple. If you use it for both personal and business reasons, you need to claim a fair business percentage.

For example, if your phone bill is £40 per month and around 50% of your calls are for business, you may claim £20 per month as a business expense.

Equipment can be slightly different. A laptop, printer, camera, tools, or machinery may be used in your business for more than one year. Depending on your accounting method, these may be treated as normal expenses or claimed through capital allowances.

Can You Claim Working From Home Costs?

Yes, many UK sole traders can claim some working-from-home costs.

If you work from home, you may be able to claim a fair part of costs such as:

Home CostCan You Claim It?ExampleElectricityYes, business portionLighting and powering your work areaHeatingYes, business portionHeating your home officeInternetYes, business portionBusiness emails, calls, uploadsRentSometimes, business portionBased on reasonable useCouncil taxSometimes, business portionIf calculated fairlyWaterSometimesMore relevant for businesses using water heavily

You can calculate actual costs or use HMRC simplified expenses. Simplified expenses let you claim a flat monthly rate instead of calculating every household bill. HMRC says you can use simplified working-from-home expenses if you work from home for 25 hours or more per month.

Hours Worked From Home Per MonthFlat Rate Per Month25 to 50 hours£1051 to 100 hours£18101+ hours£26

Simplified expenses are easier, but they may not always give you the highest claim. If your home office costs are high, actual cost calculations may be better.

Travel and Vehicle Expenses

Business travel is another common area where sole traders can claim expenses.

You may be able to claim:

• Fuel for business trips
• Parking for business meetings
• Train, bus, or taxi fares
• Hotel stays for overnight business travel
• Meals during overnight business trips
• Vehicle repairs, insurance, and servicing if using the actual cost method

But there is one important rule: normal travel between your home and your regular workplace is not usually claimable. HMRC specifically excludes travel between home and work, non-business travel, fines, and penalty charges.

If you use a car, van, or motorcycle for business, you can either claim actual business-use costs or use simplified mileage expenses. HMRC says simplified vehicle expenses allow you to use a flat rate for mileage instead of calculating the actual running costs of the vehicle.

MethodHow It WorksBest ForActual costsClaim business-use percentage of fuel, repairs, insurance, servicing, etc.Higher vehicle costsSimplified mileageClaim a flat rate per business mileEasier record keeping

Good mileage records are important. You should record the date, destination, reason for travel, and business miles.

Marketing and Website Costs

Marketing expenses are usually allowable if they are directly related to promoting your business.

You may be able to claim:

Marketing CostClaimable?Website designYesWebsite hostingYesDomain nameYesSEO servicesYesGoogle AdsYesFacebook or Instagram adsYesFlyers and business cardsYesEmail marketing toolsYesClient entertainmentUsually no

This matters because marketing is often a big cost for small businesses. A sole trader might spend money on a website, ads, social media tools, or printed material to bring in customers. These costs should be tracked properly.

Manually saving every receipt can become frustrating, especially when you are busy serving clients. Taxara’s expense tracking features can help you keep receipts and expenses organised without relying on spreadsheets.

Stock, Materials, and Goods for Resale

If you buy goods to sell, or materials to create products, these are usually business expenses.

For example:

Business TypePossible Claimable CostsOnline sellerStock, packaging, labels, delivery boxesHandmade product sellerRaw materials, tools, packagingFood businessIngredients, containers, delivery bagsBookshop or stationery sellerBooks, pens, files, notebooksTradespersonMaterials, parts, tools

The key point is that the cost must relate to your business activity. Personal shopping cannot be claimed.

Clothing Expenses

Clothing is a tricky area because HMRC does not usually allow normal clothes, even if you wear them for work.

You may be able to claim:

Clothing TypeClaimable?WhyBranded uniformYesUsed for business identityProtective bootsYesRequired for safetyHigh-vis jacketYesProtective workwearCostume for performerYesNeeded for the roleBusiness suitNoCan be worn personallyEveryday clothesNoNot only for business use

So, if you are a builder, safety boots may be claimable. If you are a consultant, a smart suit is usually not claimable.

Insurance, Legal, and Professional Fees

Many sole traders need insurance or professional support. These costs can often be claimed if they relate to your business.

Examples include:

• Public liability insurance
• Professional indemnity insurance
• Business insurance
• Accountant fees
• Bookkeeping fees
• Legal advice for business matters
• Bank charges on a business account

These costs help protect and manage your business, so they should be recorded carefully.

Some sole traders worry that accounting software will be too expensive. That is understandable, especially when you are just starting out. But software that saves time, reduces mistakes, and helps organise receipts can be worth it. You can check Taxara’s pricing to see why it is built to be affordable for sole traders.

Staff, Subcontractor, and Freelancer Costs

If you pay people to help with your business, those costs may be allowable.

This can include:

CostExampleEmployee wagesPaying a part-time assistantFreelancer feesHiring a designer or copywriterSubcontractor costsPaying another tradespersonAgency feesTemporary staff supportEmployer pension contributionsIf you employ staffEmployer National InsuranceIf applicable

However, personal costs are not allowed. For example, childcare, domestic help, or paying a family member for non-business reasons would not normally count.

Training and Courses

Training can be claimable if it improves skills you already use in your current business.

For example, a freelance designer may claim a course on advanced design software. A self-employed bookkeeper may claim a tax update course.

But a course for starting a completely different business may not be allowable. For example, if a designer takes a plumbing course to change career, that may not count as a current business expense.

Capital Allowances: Bigger Business Assets

Some items are not simple day-to-day costs. They are assets you keep and use in your business, such as machinery, tools, equipment, and business vehicles.

HMRC says capital allowances let businesses deduct some or all of the value of qualifying items from profits before paying tax.

ItemPossible TreatmentLaptopExpense or capital allowance depending on methodPrinterBusiness equipmentVanCapital allowance or mileage methodMachineryUsually capital allowanceToolsBusiness equipment

This is one area where it may be worth speaking to an accountant, especially if the item is expensive.

What Sole Traders Cannot Claim

Not every cost can be claimed. HMRC expects expenses to be genuinely business-related.

Non-Claimable CostWhy It Is Not AllowedPersonal groceriesNot a business costEveryday clothingCan be used personallyClient entertainmentUsually disallowedFines and penaltiesNot allowablePersonal holidaysNot business-relatedNormal commutingHome-to-work travel is not allowedFamily costsNot wholly for businessPrivate phone useOnly business portion can be claimed

A simple test is this: would you still buy it if you did not run your business? If the answer is yes, be careful. You may only be able to claim part of it, or none of it.

Keep Clear Records

Good records matter. HMRC is moving more tax processes into digital systems, so sole traders should get used to keeping income and expense records properly. This is especially important with Making Tax Digital obligations affecting many self-employed people.

You should keep:

If you work on the move, it is easy to lose receipts from cafés, trains, shops, or suppliers. With Taxara, you can <a href="https://taxara.app/landing-page" target="_blank" rel="noopener">track expenses from your phone</a>, which makes it easier to capture costs while they are fresh.

Common Mistakes Sole Traders Should Avoid

Many sole traders lose money or create tax problems because of simple mistakes.

Common mistakes include:

• Mixing personal and business spending
• Forgetting small costs like postage or subscriptions
• Not recording mileage
• Claiming full costs when there is personal use
• Losing receipts
• Claiming client entertainment
• Not reviewing expenses before Self Assessment
• Waiting until the deadline to organise records

On the income side, getting paid properly also matters. Once the related guide is live, you can link to your blog about invoicing as a freelancer here.

Final Thoughts

As a UK sole trader, you can claim many business expenses, but they must be genuine, reasonable, and properly recorded. Office costs, travel, home-working costs, marketing, stock, insurance, professional fees, training, and staff costs can all reduce your taxable profit when claimed correctly.

The main rule is simple: claim only what relates to your business. If something has mixed personal and business use, claim only the business portion.

Tracking expenses is just one part of managing your tax properly. Choosing the right tax tool for your business can help you stay organised throughout the year instead of rushing at tax return time.
