Self Employed Painter and Decorator Tax: Stop Leaving Money on Walls
Most self-employed painters and decorators overpay tax by missing legitimate expense claims. Here's what HMRC allows and what MTD changes from April 2026.
Most self-employed painters and decorators overpay tax every single year, not through any fault of their own, but because HMRC's guidance on allowable expenses reads like it was written for an accountant, not someone who spends their days up a ladder in Dulux-spattered overalls.
If you're turning over somewhere between £30,000 and £80,000 a year as a self-employed painter and decorator, there is a realistic chance you are handing HMRC hundreds of pounds more than you legally owe. This post names exactly what you can claim, what is changing with Making Tax Digital from April 2026, and how to stop subsidising the Treasury out of ignorance.
- Self-employed painters and decorators can claim a wide range of trade-specific expenses that many miss, including overalls, specialist tools, and vehicle costs.
- Making Tax Digital for Income Tax (MTD ITSA) will require quarterly digital submissions from April 2026 for anyone earning over £50,000, and April 2027 for those earning over £30,000.
- Failing to keep digital records from the start of the relevant tax year, not just at filing time, is where most tradespeople will fall foul of the new rules.
- A simplified expenses claim for your vehicle can save hours of record-keeping and still reduce your tax bill significantly.
- Getting your allowable expenses right now builds the habits that MTD will legally require in 18 months.
The Expense Problem Nobody Warns You About
HMRC allows sole traders to deduct expenses that are incurred "wholly and exclusively" for the purpose of the business. Simple in principle. Maddening in practice, because painting and decorating straddles a peculiar line: your tools are trade-specific, your materials are often job-specific, and your van is probably doing double duty on school runs.
The result is that many self-employed painters and decorators either claim too little (because they are not sure what counts) or claim too much (and risk an HMRC enquiry). Both outcomes cost money.
- Wholly and Exclusively
- HMRC's test for whether a business expense is allowable. The cost must be incurred entirely for business purposes. Where an expense has a dual personal and business purpose, only the business portion is deductible, unless the two uses can be clearly separated.
What a Self-Employed Painter and Decorator Can Actually Claim
Materials and Supplies
This one seems obvious, but the detail matters. Paint, filler, primer, masking tape, sandpaper, brushes, rollers, trays, and any other consumables purchased specifically for client jobs are fully allowable. Keep your receipts, or better still photograph them immediately using an MTD-compliant app, because a receipt stuffed in the glove box of your van has a survival rate of roughly three weeks.
If you buy materials speculatively, intending to use them on future jobs, they are still claimable in the tax year you purchase them, as long as the purchase is genuinely business-motivated.
Protective Clothing and Overalls
HMRC allows claims for clothing that is either protective or clearly identifiable as a work uniform. Overalls, disposable coveralls, safety boots, gloves, dust masks, and goggles all qualify. What does not qualify is anything you could conceivably wear outside work, which is why a pair of old jeans, even if ruined by paint, will not pass muster. Branded overalls with your business name on them sit in a stronger position.
A typical set of annual spend here might be £200 to £400 for a working painter. At the basic rate of 20%, that is £40 to £80 in tax saved on clothing alone, which is not life-changing, but it is money that belongs to you.
Tools and Equipment
Brushes, rollers, extension poles, spray equipment, dust sheets, ladders, scaffolding towers, pressure washers, and similar tools used exclusively for work are allowable. Small items (typically under £100) are usually claimed as revenue expenditure in full in the year of purchase. Larger items, say a professional airless sprayer costing £1,500, may need to be claimed through the capital allowances regime, though the Annual Investment Allowance means most sole traders can still write the full cost off in year one.
Your Van or Vehicle
This is where self-employed painters and decorators most commonly leave money on the table, and also where HMRC is most likely to scrutinise a claim.
You have two options:
Simplified flat rate mileage: HMRC allows you to claim 45p per mile for the first 10,000 business miles in a tax year, and 25p per mile thereafter. You simply log your business journeys, multiply, and deduct. No fuel receipts, no insurance apportionment, no arguments about personal use. If you drive 12,000 business miles in a year, that is (10,000 x £0.45) + (2,000 x £0.25) = £4,500 + £500 = £5,000 deducted from your taxable income. At 20% tax, that is £1,000 back in your pocket.
Actual costs method: You claim the actual running costs of the vehicle (fuel, insurance, servicing, MOT, road tax) but only the business proportion. If 70% of your mileage is business-related, you claim 70% of each cost. This requires more meticulous record-keeping and is only advantageous if your actual costs exceed what the flat rate would give you.
You must choose one method and stick with it for the life of that vehicle. Most decorators find the flat rate simpler and often more generous.
Travel and Parking
Parking fees incurred while visiting client sites are allowable. Congestion charges and road tolls on business journeys are allowable. What is not allowable is the ordinary commute from your home to a regular place of work, but as a sole trader whose sites change constantly, most of your travel will qualify.
Phone and Internet
If you use your mobile phone to quote jobs, communicate with clients, and order materials, the business proportion of your bill is deductible. If you use your phone exclusively for business, claim 100% of the cost. If it is a personal phone used partly for work, make a reasonable estimate (60% business use is not uncommon for tradespeople) and apply that percentage to your bill.
Public Liability Insurance and Trade Insurance
Fully allowable. If you pay £400 a year for public liability insurance, that £400 comes off your taxable income.
Advertising and Marketing
Your website hosting, domain name, business cards, leaflets, any paid ads on Google or social media, and your listing on trade directories all count as allowable business expenses.
Accountancy and Professional Fees
If you pay an accountant to prepare your Self Assessment return, that fee is itself a deductible expense. There is a certain satisfaction in that.
The CIS Wrinkle: Construction Industry Scheme
If you work as a subcontractor on sites managed by a main contractor, there is a reasonable chance you are operating within the Construction Industry Scheme (CIS). Under CIS, your contractor deducts 20% (or 30% if you are not registered) from your payments and sends it directly to HMRC on your behalf.
This is not tax already paid in full. It is a payment on account against your eventual Self Assessment liability. Come January 31st, HMRC calculates what you actually owe, deducts what has already been paid under CIS, and either asks for more or issues a refund.
The important thing here is that if you are having CIS deductions made, you must still file a Self Assessment return, and you must still claim your allowable expenses, because those deductions are calculated on your gross income before expenses. The refunds available to painters and decorators who have been paying CIS deductions but not claiming their full expenses can be substantial.

Making Tax Digital Is Coming for Your Paintbrush
From April 2026, any self-employed painter and decorator with annual income over £50,000 must comply with Making Tax Digital for Income Tax Self Assessment (MTD ITSA). From April 2027, the threshold drops to £30,000. A third tier at £20,000 is expected by the end of the decade.
What does compliance actually mean in practice?
Digital record-keeping from day one of the tax year. Not a shoebox of receipts sorted in January. Every income transaction and every expense must be recorded digitally as you go, in software that is HMRC-recognised.
Four quarterly submissions per year. You submit a summary of your income and expenses to HMRC four times a year, broadly every three months. These are not tax payments; they are data submissions. But miss one, and the penalties framework kicks in fast. The cumulative penalty model means that missing multiple quarters can cost you hundreds of pounds before HMRC issues a formal assessment. For a sobering breakdown of what late submissions actually cost, read What Happens If You Miss an MTD Deadline: The Real Cost.
An End of Period Statement and a Final Declaration. At year end, you confirm your figures are correct and finalise your tax position. This replaces the single annual Self Assessment return you are used to.
The practical implication for a painter and decorator is that the habits you build around expense tracking right now will either make MTD manageable or make it a quarterly ordeal. A simple MTD-compatible app that lets you photograph receipts on-site and log mileage immediately after each job is the difference between a 15-minute quarterly submission and a weekend of archaeology through your van's door pockets.

A Concrete Scenario: What the Numbers Look Like
Consider a self-employed painter and decorator turning over £55,000 in 2024/25. After the personal allowance of £12,570, they are taxable on £42,430 before any expenses. At the basic rate, their income tax bill before expenses would be roughly £8,486, plus Class 4 National Insurance contributions.
Now add a realistic set of allowable expenses:
- Materials and consumables: £8,000
- Van (flat rate mileage, 11,000 business miles): £4,750
- Tools and equipment: £1,200
- Overalls and PPE: £350
- Public liability insurance: £450
- Phone (80% business use on a £600/year contract): £480
- Advertising and website: £300
- Accountancy fees: £600
Total allowable expenses: £16,130
Taxable profit: £55,000 minus £16,130 equals £38,870. After the personal allowance, taxable income is £26,300. Income tax at 20% is £5,260. Class 4 NI on profits between £12,570 and £38,870 is roughly £1,629.
Without those expense claims, the same decorator would be paying income tax on £42,430 of profit after allowance, around £8,486 in income tax plus higher NI contributions. The difference in income tax alone is over £3,200 for the year, simply from claiming what is legitimately owed.

The Record-Keeping Habit That Pays For Itself
The single most expensive thing a self-employed painter and decorator can do is rely on memory. A job done in March, paid in cash, with materials bought from a local merchant on a card that also does the weekly shop: by January of the following year, the details are gone.
A simple discipline: at the end of each working day, spend two minutes logging what you spent and what you invoiced. Photograph every receipt immediately. Record every business journey before you start the engine if possible, or immediately on arrival. This takes less time than making a cup of tea, and it is the exact behaviour that MTD ITSA will legally require within the next 18 months anyway.
The tradespeople who will find MTD least disruptive are not the ones who scramble to get compliant in March 2026. They are the ones who have already built the habit, for whom a quarterly submission is just pressing a button because the data is already there.

The Opening Question, Answered
Are you leaving money on the walls? If you are not systematically claiming every allowable expense, from your mileage to your overalls to your accountant's invoice, then yes, almost certainly. The irony is that HMRC's rules are not especially harsh for painters and decorators. The trade has a wide range of legitimate, well-established deductions. The problem is that nobody sits you down and explains them when you first go self-employed.
The one concrete action you can take today: open a notes app on your phone and log every business-related purchase and journey you make this week. Do not wait for a receipt. Do not wait for the end of the month. Just start the record. That single habit, applied consistently between now and April 2026, is worth more to your tax position than any clever scheme.
