Tax Guide for Self-Employed Tilers

Tiling is construction work that falls under the Construction Industry Scheme (CIS). If you work as a self-employed tiler, your contractor deducts 20% from your payments and sends it to HMRC as tax. At the end of the tax year, you file Self Assessment — and the expenses you claim often mean a significant refund.

Tilers go through consumables fast — adhesive, grout, spacers, and diamond blades — and specialist wet saws are a significant investment. Those costs add up, and every one is deductible.

What You Can Claim

Expense	Examples	Typical Annual Cost
Tools & equipment	Notched trowels, grout floats, tile nippers, spirit levels, mixing drill and paddle	£100–£400
Tile cutters	Manual cutter (Vitrex, QEP), electric wet saw (Rubi DU-200 ~£530, Rubi DT-180 ~£715)	£100–£800
PPE & workwear	Professional knee pads, safety boots, dust masks, safety goggles, ear defenders	£150–£350
Vehicle costs	Van fuel, insurance, MOT, servicing, road tax	£4,000–£6,000
Materials & consumables	Adhesive, grout, spacers, sealant, diamond blades, levelling clips (not supplied by client)	£300–£1,500
Insurance	Public liability, tool cover	£60–£200
Training & certifications	CSCS card renewal, NVQ assessment fees, first aid course	£100–£500
Phone & apps	Mobile contract (business portion), job management apps	£150–£300
Professional memberships	The Tile Association (TTA) — fixer membership £150+VAT/year	£150–£200
Accounting fees	Tax return preparation, bookkeeping	£150–£400

Tile Cutters: Your Key Investment

A decent manual cutter (£40–£160) handles most wall tiles. For porcelain, natural stone, and large-format floor tiles, you need an electric wet saw. Entry-level models start around £50, but professional saws (Rubi, Raimondi) run £500–£2,500. If you hire rather than buy, hire charges are fully deductible (~£70/day from builders' merchants).

Certifications That Count

CSCS Blue Skilled Worker card — needed for site access. Requires NVQ Level 2 in Wall and Floor Tiling plus the CITB HS&E test (~£58 combined, valid 5 years)
NVQ Level 2/3 in Wall and Floor Tiling — on-site assessment fees are deductible (~£550–£999)
TTA membership — deductible as a professional subscription (£150+VAT/year for fixers)

HMRC Flat Rate Alternative

HMRC allows a £60/year flat rate deduction for tools and specialist clothing instead of claiming actual costs. For tilers, knee pads and diamond blades alone cost more than this — claim the real figures with receipts.

Expenses You Can't Claim

Commuting to a regular site — travel to the same location for over 24 months isn't deductible. Travel between different jobs is
Everyday clothing — jeans and trainers don't qualify. Only specialist PPE counts (knee pads, dust masks, safety boots)
Your original tiling qualification — your initial NVQ or college course isn't deductible. Only renewals, upgrades, and CPD count
Fines and penalties — parking tickets, PCNs, late filing penalties
Food and drink — unless you're working away from your normal area overnight

Example: How Much Tax Does a Tiler Pay?

Ryan works as a self-employed tiler through CIS. Here's his 2025/26 tax year:

Item	Amount
CIS income (gross)	£38,000
CIS deducted (20%)	£7,600
Allowable expenses	£7,200
Taxable profit	£30,800
Income Tax (after £12,570 personal allowance)	£3,646
Class 2 NI (£3.50/week × 52)	£182
Class 4 NI (6% on £12,570–£50,270)	£1,094
Total tax + NI due	£4,922
CIS already deducted	£7,600
Refund due	£2,678

Without claiming expenses, his refund would be just £806. Expenses save Ryan £1,872. You can claim back your CIS deductions through your Self Assessment return.

Record Keeping Tips

Track consumable costs per job — adhesive, grout, spacers, and sealant costs vary widely between jobs. Recording costs per project makes your expense claims easier to justify
Keep tile cutter and wet saw invoices — these are larger purchases that HMRC may query. Note whether each item was bought or hired
Photograph builders' merchant receipts — receipts for adhesive, grout, and diamond blades from Topps Tiles, Tile Giant, or builders' merchants fade on thermal paper. Snap them the same day
Save your CIS payment statements — you need these to reclaim the 20% deduction. Chase your contractor for missing ones before January
Log every site and journey — note the site address and mileage each day. Many tilers work one bathroom or kitchen per week, so the log is straightforward

Key Deadlines

Deadline	What
5 April	Tax year ends — finalise your income and expense records
31 January	File Self Assessment and pay any tax owed (or receive your refund)
31 July	Second payment on account (if applicable)

If this is your first year, register for Self Assessment by 5 October after the tax year ends.

VAT Threshold

With day rates of £150–£300, experienced tilers working steadily can approach the £90,000 VAT threshold (2025/26) — especially those supplying tiles alongside labour. At £250/day for 48 weeks, that's £60,000 from labour alone. Add material supply and your turnover climbs quickly. Monitor your rolling 12-month total, based on turnover not profit.
