Self-Employed Tiler Tax in the UK 2026/27: Profit, NI and What You Keep
How a self-employed tiler's profits are taxed in 2026/27, with a worked Income Tax and Class 4 National Insurance example and the deductible expenses that matter most.
How tiling profit gets taxed
A self-employed tiler is taxed on business profit — turnover from tiling jobs minus allowable expenses such as tile cutters, adhesives, grout, spacers, van costs and protective equipment. That profit figure, not the cash a tiler physically banks, is what goes on the Self Assessment return and is subject to Income Tax and Class 4 National Insurance.
Worked example: £35,000 profit
Taxable income: £35,000 − £12,570 personal allowance = £22,430, entirely within the 20% basic rate band, giving Income Tax of £4,486. Class 4 National Insurance applies at 6% on profit between £12,570 and £50,270: (£35,000 − £12,570) × 6% = £1,346. Total tax and NI: £5,832, leaving take-home profit of roughly £29,168.

Crossing £50,270
Profit above £50,270 is taxed at 40% Income Tax, while Class 4 National Insurance drops to 2% on the excess — a combined marginal rate of 42% on that slice, down from 26% below the threshold. Many tilers use this as a trigger to review pension contributions, since pension payments reduce taxable profit.

Frequently asked questions
How is a self-employed tiler taxed in the UK?
Self-employed tilers pay Income Tax and Class 4 National Insurance on their business profit — turnover minus allowable expenses — reported through Self Assessment, rather than having tax deducted at source through PAYE.
How much tax does a tiler pay on £35,000 profit in 2026/27?
On £35,000 profit, Income Tax is £4,486 (20% on income above the £12,570 personal allowance) and Class 4 National Insurance is £1,346 (6% on profit between £12,570 and £50,270), leaving roughly £29,168 after tax and NI.
Can a tiler claim tools and materials as expenses?
Yes, tile cutters, trowels, spacers, adhesives, grout, van running costs and protective equipment used wholly for the business are generally allowable expenses that reduce taxable profit.
Is Class 2 National Insurance still payable by self-employed tilers?
Class 2 National Insurance was abolished for most self-employed people from April 2024. Profits above the small profits threshold of £7,105 are treated as if Class 2 had been paid, protecting state pension entitlement without an actual charge.
Should a self-employed tiler register for VAT?
Only if turnover exceeds the £90,000 VAT registration threshold in any rolling 12-month period, or is expected to. Most sole-trader tilers stay below this and are not required to register.
Can a tiler claim a home office or storage space?
Yes, a reasonable proportion of home running costs used for admin, invoicing and material storage can be claimed using either simplified flat rates or an actual-cost apportionment method.
Does a company van count as a business expense for a tiler?
Van purchase costs, fuel, insurance, and maintenance used for business travel between jobs and merchants are generally allowable, either through capital allowances on purchase or as a running expense if leased.
What happens if a tiler's profit crosses £50,270?
Profit above £50,270 is taxed at 40% Income Tax and Class 4 National Insurance drops to 2% on the excess, so the combined marginal rate on that slice falls from 26% to 42%.
