The short answer
- A cost counts if it is wholly and exclusively for the workIf a cost also serves a private purpose, such as everyday clothes or lunch, it fails. Where a clear part of a bill is for work, like the business share of a phone, that part counts.
- Mileage between clients is claimable at up to 55p a milegov.uk’s flat rate for 2026 to 2027 is 55p a mile for the first 10,000 business miles and 25p a mile after that. You can claim the business share of actual car costs instead, but not both.
- Small costs may be better covered by the £1,000 allowanceYou can take a flat £1,000 off your income instead of claiming expenses. If your real costs for the year are more than that, claiming them is worth more.
- Keep the receipts for five years after the deadlineRecords must be kept for at least 5 years after the 31 January deadline for that year's return. A photo of each receipt, filed by month, is enough.

The test HMRC applies
What “wholly and exclusively” means for a carer
Every question about expenses comes back to one sentence in the law: a cost can be deducted from your trading income only if it was spent wholly and exclusively for the purposes of the trade. Knowing how HMRC reads that sentence answers most of the questions carers ask before they reach a list.
Four terms worth knowing before you claim anything
- Allowable expense
- A cost of running your business that comes off your income before Income Tax and Class 4 National Insurance are worked out. It lowers your profit, which is the figure you are taxed on.
- Wholly and exclusively
- The work has to be the only reason for the cost. HMRC’s manual says that if a non-business purpose is found, the expense is not allowable, even if there were good business reasons as well.
- Dual purpose
- A cost that serves you and the work at once in a way that cannot be split, such as a warm coat you wear on visits and at the weekend. It fails the test entirely.
- Apportionment
- Where a definite part of a cost is for the work, such as the calls you make to clients on your phone, that part is allowable and the rest is not.
The difference between the last two terms is the one that matters most in practice. HMRC's manual at BIM37007 says a cost with a mixed purpose cannot be partly claimed, while BIM37600 allows a claim for a definite part or proportion that was spent only for the work. A phone contract is the usual example. Your calls to clients and families can be separated from your personal calls, so the business share counts. A pair of black trousers cannot be split in the same way, because you would need to wear something whatever your job.
The manual also allows for a private benefit that comes along with a cost made purely for work. A moving and handling course that also helps you lift your own shopping more safely is still a work cost, because the work is why you paid for it.
Your costs come out of what reaches you, not out of what the client is charged. On PrimeCarers a £20 hour of care pays the carer £16 after our 20% commission, and your travel, uniform and phone are paid for out of that £16. What carers earn on PrimeCarers sets out the commission in full. This guide is one of the carer resources on tax and paperwork, and it goes further into expenses than tax and money as a self-employed carer, which covers registering and the rates you pay.
What counts
The costs carers meet, grouped by HMRC's answer
Here are the costs that come up in care work, sorted into what HMRC allows, what it allows only in part or in some cases, and what it does not allow. Each row names the gov.uk page or the section of HMRC's Business Income Manual it comes from, so you can read the rule for yourself.
Allowed
Costs that exist only because of the care work.
A uniform and protective clothing
A care tunic or uniform, and protective items such as disposable gloves and aprons. HMRC’s manual gives a nurse’s uniform as an example of clothing whose design is dictated by the work and by hygiene.

Insurance you hold for the work
Any policy you take out for the business, such as public liability or professional indemnity cover.
Training that keeps your care skills current
A course that updates or adds to skills you already use as a carer, such as a moving and handling refresher, or an ancillary skill such as bookkeeping.

Professional memberships and journals
Membership of a trade body or professional organisation related to your work, and trade or professional journals.

Travel between one client and the next
Fuel, parking and fares for journeys made for the work during your working day. HMRC’s manual treats travel to and between the places a job is done as a trade cost.
Source: gov.uk: travel expenses, HMRC BIM37620
Allowed in part, or only in some cases
Things you use for work and for yourself, where only the business share counts.
Your mobile phone and contract
The share of the bill that is for arranging and carrying out visits. gov.uk’s own example is a £200 phone bill of which £70 was for business, so £70 is claimed.
Source: gov.uk: office and phone costs, gov.uk: expenses overview
Home broadband
The business share only, worked out on a basis you could explain to HMRC if asked.
Source: gov.uk: office and phone costs
Your car
Either the business share of the actual running costs, or a flat rate for each business mile: 55p a mile for the first 10,000 miles in 2026 to 2027 and 25p after that. Not both, and the choice stays with that car.

Travel from home to a client
Travel between home and a fixed place of work is not allowed. The manual records a court allowing a self-employed tradesman’s travel from home to a changing series of sites, and refusing it for a milkman with a fixed round. Which side you fall on depends on the facts.

Meals away overnight
Meals on an overnight business trip are allowed. Food on an ordinary working day is not, which is the next group.
Source: gov.uk: travel expenses
Not allowed
Costs with a private purpose, even if the work is why you spent the money.
Everyday clothes, even if you keep them for work
Black trousers, trainers or a fleece that could be worn anywhere. The courts have held that ordinary clothing always serves the private purpose of being clothed.
Source: gov.uk: clothing expenses, HMRC BIM37910
Food and drink on a normal working day
A sandwich between visits is not a business cost, however long the day. HMRC’s manual says everyone must eat to live.
Source: HMRC BIM37920
Parking and speeding fines
Fines and penalty charges are excluded, even when they were picked up on the way to a client.
Source: gov.uk: travel expenses
Training for a new line of work
A course taken to start a business, or to move into work unrelated to caring, is unlikely to be allowed.
Source: gov.uk: training courses, HMRC BIM35660
Gym membership and charity donations
gov.uk names both as costs you cannot claim, whatever the physical demands of the job.

Money you take out for yourself
What you pay yourself from the business is not an expense. Tax is worked out on the profit before you take it.

A few of these are worth a word more than a table row can give them.
Uniform. gov.uk allows uniforms and protective clothing and rules out everyday clothing, even if you only wear it for work. The line HMRC's manual draws at BIM37910 is whether the design is dictated by the job. A care tunic is. A plain navy top you have decided to keep for visits is not, because it would do just as well as ordinary clothing.
Training. A course that improves skills you already use as a carer is allowable. HMRC's manual at BIM35660 says training that lets somebody start a new business, or move into an unrelated area of work, is unlikely to be. So a refresher in medication awareness taken while you are working as a carer is a cost of the business, while a course taken to get into caring from another line of work is not. Training for private carers covers which courses are worth doing, and keeping your carer certifications up to date covers refreshers.
Insurance. Any policy you hold for the business, such as public liability cover, is allowable. What insurance a self-employed carer needs, and what it costs, is set out in do I need insurance as a self-employed carer?.
Travel and your car
Travel between clients, travel from home, and claiming for your car
For most carers who drive, travel is the largest cost of the year, so it is where the rules matter most. There are two separate questions: which journeys count, and how you put a figure on the cost of the car.
Two ways to claim for a car you use for work
| Actual costs | Simplified flat rate | |
|---|---|---|
| What you claim | The business share of what the car costs to run: fuel, insurance, repairs, servicing, road tax and breakdown cover. | A fixed amount for each business mile. For 2026 to 2027: 55p a mile for the first 10,000 miles and 25p a mile after that, or 24p a mile on a motorcycle. |
| Buying the car | Claimed through capital allowances rather than as a running cost. | Covered by the flat rate. You cannot use the flat rate for a vehicle you have already claimed capital allowances on. |
| What you need to record | Every running cost, the total miles in the year and the business miles, so you can work out the share. | Your business miles. A log of each journey with the date, the places and the distance. |
| Changing later | You can move to the flat rate only for a vehicle that has not had capital allowances claimed on it. | Once you use the flat rate for a vehicle, you keep using it for as long as that vehicle is used in the business. |
What you claim
- Actual costs
- The business share of what the car costs to run: fuel, insurance, repairs, servicing, road tax and breakdown cover.
- Simplified flat rate
- A fixed amount for each business mile. For 2026 to 2027: 55p a mile for the first 10,000 miles and 25p a mile after that, or 24p a mile on a motorcycle.
Buying the car
- Actual costs
- Claimed through capital allowances rather than as a running cost.

- Covered by the flat rate. You cannot use the flat rate for a vehicle you have already claimed capital allowances on.
What you need to record
- Actual costs
- Every running cost, the total miles in the year and the business miles, so you can work out the share.

Changing later
- Actual costs
- You can move to the flat rate only for a vehicle that has not had capital allowances claimed on it.
- Simplified flat rate
- Once you use the flat rate for a vehicle, you keep using it for as long as that vehicle is used in the business.
Rates from gov.uk’s simplified expenses page for vehicles, 2026 to 2027 tax year, checked 22 September 2026. Before 6 April 2026 gov.uk’s figure for the first 10,000 miles was 45p a mile.
Which journeys count. Driving from one client to the next during your working day is travel for the business. gov.uk's list of costs you cannot claim includes "travel between home and work", and HMRC's manual at BIM37605 explains why: where there is a fixed place of work, living somewhere else is a private choice, so the journey has a private purpose.
The manual does not stop there, and it is worth reading the next two pages before assuming your first journey of the day is lost. BIM37620 describes a bricklayer who worked on a series of building sites from a base at home, where he kept his tools and his books. The court allowed his travel from home to the sites, because his trade was an itinerant one. BIM37635 describes a milkman with a fixed round from one depot, whose travel from home to the depot was refused, and the judge drew the difference from how predictable the places of work were. The manual says each case turns on its facts. It does not say which side a carer visiting clients' homes falls on, so this guide does not either. If your first and last journeys of the day are a large part of your mileage, ask HMRC or an accountant about your own pattern of work before you claim them.
Mileage a client pays you. Whether a client pays you anything towards travel is a separate question from tax, and it is set by your agreement with them. Travel time and mileage for carers covers charging for it, building it into your rate, and keeping clients close together. Your car insurance also has to cover driving for work, which is a question for your insurer: what car insurance do I need as a home carer? explains what to ask for.
The £1,000 allowance
The £1,000 trading allowance, as an alternative to claiming costs
Instead of adding up your costs, you can take a flat £1,000 off your trading income for the year. You cannot do both in the same tax year: if you use the allowance, no other expenses or allowances can be deducted.
Choosing between the allowance and your real costs
| Use the £1,000 allowance | Claim your costs | |
|---|---|---|
| What comes off your income | A flat £1,000, whatever you spent. | The total of your allowable costs for the year. |
| When it is worth more | When your allowable costs for the year come to less than £1,000. | When your allowable costs come to more than £1,000. |
| Receipts | Not needed for the costs, because you are not claiming them. You still keep a record of what you were paid. | Needed for every cost you claim, kept for five years after the filing deadline. |
| If your trading income is £1,000 or less | gov.uk says you may not have to tell HMRC about it at all. | You can still choose to claim your costs instead of using the allowance. |
What comes off your income
- Use the £1,000 allowance
- A flat £1,000, whatever you spent.
- Claim your costs
- The total of your allowable costs for the year.
When it is worth more
- Use the £1,000 allowance
- When your allowable costs for the year come to less than £1,000.
- Claim your costs
- When your allowable costs come to more than £1,000.
Receipts
- Use the £1,000 allowance
- Not needed for the costs, because you are not claiming them. You still keep a record of what you were paid.
- Claim your costs
- Needed for every cost you claim, kept for five years after the filing deadline.
If your trading income is £1,000 or less
- Use the £1,000 allowance
- gov.uk says you may not have to tell HMRC about it at all.
- Claim your costs
- You can still choose to claim your costs instead of using the allowance.
From gov.uk’s guidance on tax-free allowances on property and trading income, checked 22 September 2026. The allowance cannot be used on income from a company or partnership you or someone connected to you controls, or from your employer.
For a carer who drives between clients, the arithmetic usually settles itself. A few thousand business miles at 55p a mile soon passes £1,000 before a uniform or a phone bill is added. The allowance suits somebody whose caring income is small and whose costs are smaller still, such as a carer who walks to one or two local clients a week. Adding up your likely costs for the year before you file is the way to tell which side you are on.
Registering for Self Assessment once your income is over £1,000, and filing the return itself, are covered in how to pay tax as a self-employed carer.
Costs a client repays
Costs a client repays are a separate arrangement from your tax
Claiming a cost against tax and asking a client to pay you back for it are two different things. Tax relief lowers the tax on your profit. Repayment from a client is money agreed between the two of you under your contract, and the contract sets the conditions.
- 1
Agree it before you spend anything
Out-of-pocket costsUnder the contract between you and each client, out-of-pocket expenses are repaid only where the client has agreed the arrangement in advance. Buying something first and asking afterwards gives the client no obligation to pay. - 2
Keep the receipt and hand over a copy
Every timeThe contract makes repayment subject to receipts or other evidence of what you paid. The same receipt is part of your own records. - 3
Put any travel arrangement in writing
Travel and mileageTravel is left out of the general expenses clause. It is chargeable only if agreed in advance, in writing, with the rate and the circumstances set out. Where it is agreed, 55p a mile is the usual figure on PrimeCarers. - 4
Count what you are repaid as money received
On your returnAnything a client pays you is money your business has received. If you are unsure how a repaid cost should appear on your return, HMRC or an accountant can tell you.
Most of what a carer spends never goes near a client: your car, your uniform and your phone are costs of running your own business. Repayment usually comes up for smaller things bought on a client's behalf, such as a prescription collected on the way to a visit. Buying things with a client's own money is a different arrangement again, with its own risks, and handling money for clients safely covers it.
If you want to see what families are told about this side of the arrangement, what families are told about paying a carer's travel time and mileage is the page written for them. Every client you meet through PrimeCarers, and anybody that client refers to you, is booked and paid through PrimeCarers.
Records and MTD
The records to keep, for how long, and when Making Tax Digital applies
HMRC does not ask to see your receipts when you file. It can ask later, so you must keep them for at least 5 years after the 31 January deadline for the return they belong to. For example, a return for 2026 to 2027 is due by 31 January 2028, so its records are kept until at least the end of January 2033.
What to keep, as you go
0 of 7 ticked
For every cost you claim
For your car
For your phone and broadband
For the money coming in
gov.uk lists receipts, bank statements and invoices as the proof your records should rest on. If records are lost or destroyed, gov.uk says to use your best estimate and tell HMRC that the figures are estimated or provisional. That is a fallback, and it is far easier to keep the photos from the start. Self-employed carer documents covers the other paperwork worth keeping together.
Making Tax Digital for Income Tax changes how you send HMRC your figures once your income passes a threshold. It uses your qualifying income, which gov.uk defines as your total self-employment and property income before expenses, not your profit. The thresholds on gov.uk are:
- £50,000 of qualifying income in 2024 to 2025: Making Tax Digital from 6 April 2026, so it already applies in the 2026/27 tax year.
- £30,000 in 2025 to 2026: from 6 April 2027.
- £20,000 in 2026 to 2027: from 6 April 2028.
If it applies to you, you keep your records digitally in compatible software and send updates every quarter, and the same rules about which costs are allowable still apply. Find out if and when you need to use Making Tax Digital on gov.uk, which also explains the exemptions.
If you are setting up and want your costs to count from the first visit, you can register as a carer on PrimeCarers and set a rate with them in mind, or see the carer jobs open near you first.
Questions
Questions carers ask about expenses
Costs spent wholly and exclusively for the work: a uniform and protective clothing, insurance you hold for the business, training that keeps your care skills current, professional memberships, and travel between clients. Your phone, broadband and car count in part, for their business share. Everyday clothes, ordinary meals, fines and gym membership do not count. gov.uk’s guide to expenses if you’re self-employed has the full list.
If you use gov.uk’s simplified flat rate, it is 55p a mile for the first 10,000 business miles in the tax year and 25p a mile after that, or 24p a mile on a motorcycle. Before 6 April 2026 the first figure was 45p a mile, which is why older guides still quote it. You can claim the business share of actual car costs instead, but not both for the same vehicle.
Not if it counts as travel between home and a fixed place of work, which gov.uk rules out. HMRC’s manual records a court allowing travel from a home base to a series of changing sites, and refusing it for a fixed, predictable round, and says each case depends on its facts. Ask HMRC or an accountant about your own pattern of work before you claim it.
Not if they are everyday clothes that could be worn anywhere, even if you keep them only for work. gov.uk allows uniforms and protective clothing, and HMRC’s manual draws the line at whether the design is dictated by the job.
Use whichever takes more off your income. If your allowable costs for the year come to more than £1,000, claiming them is worth more. If they come to less, the allowance is, and you do not need receipts for costs you are not claiming. You cannot use both in the same tax year.
Yes. You need an enhanced DBS to do the work, so the fee for the check and, if you join it, the yearly Update Service subscription are costs of the business. On PrimeCarers you pay for these yourself, and our commission covers checking your DBS when you register. It needs to have been issued within the last 18 months, and it has to be renewed every 18 months.
At least 5 years after the 31 January filing deadline for the tax year they belong to. For the 2026 to 2027 tax year, whose return is due by 31 January 2028, that means keeping them until at least the end of January 2033.
