Making Tax Digital for bricklayers: what changes from April 2026

TL;DR: Making Tax Digital for Income Tax Self Assessment (MTD ITSA) applies to self-employed UK bricklayers in three income steps: over £50,000 from 6 April 2026, over £30,000 from 6 April 2027, and over £20,000 from 6 April 2028. Three real changes land at once: your records must be digital from the point of capture, you submit four quarterly summaries of income and expenses to HMRC each year on top of your annual declaration, and you need HMRC-compatible filing software. The underlying tax calculation does not change. Same money, different rhythm. Bricklayers face specific wrinkles around cash income, materials cycling, seasonal weather-driven gaps, and CIS deductions. Quarterly reporting makes all of these more visible than a once-a-year tax return ever did. This post sets out what actually changes, what stays the same, and how to stay compliant without over-engineering your record-keeping.

If you work as a self-employed bricklayer or sole-trader builder in the UK, the MTD ITSA headline is straightforward. Mandatory digital records and quarterly submissions in three steps:

• From 6 April 2026, qualifying income over £50,000.
• From 6 April 2027, qualifying income over £30,000.
• From 6 April 2028, qualifying income over £20,000.

Qualifying income is your combined self-employment and property income. If you rent out a van or a tool store alongside your building work, that rental income counts toward the same total.

The three real changes:

1. Digital records from the start, not reconstructed at year-end. Your income and expenses must be held in a structured digital format throughout the year. A spreadsheet can work if it pairs with MTD-compatible bridging software. Cloud accounting handles both natively. Pulling receipts out of a van glovebox in January is no longer a compliant approach.
2. Four quarterly summary submissions per tax year, plus a year-end final declaration. Quarterly updates are lightweight by design: total income by category, total expenses by category. The tax calculation still happens at year-end. The rhythm changes, not the complexity.
3. HMRC-compatible filing software. The existing self-assessment portal will not accept MTD ITSA submissions. You need cloud accounting software with direct MTD submission built in, or a spreadsheet paired with bridging software (typically £30–£50 per year).

Worth saying plainly: quarterly figures are provisional. They are not mini tax returns. They show HMRC your business is active and give a running picture. No additional tax calculation happens at the quarterly stage.

Most service businesses have relatively clean income and expense categories. Bricklaying has layers that matter specifically for quarterly reporting.

Cash income and invoicing discipline. A proportion of smaller bricklaying jobs are paid in cash at completion. Under MTD, every payment received must be recorded digitally in the period it arrives. Cash jobs that were previously noted loosely and reconciled at year-end now need to be entered at the time. This is not a new tax obligation. Cash income has always been taxable. It is a new recording discipline that catches up with anyone who has been informal about it.

Materials cycling: bricks, sand, cement, and fixings. A bricklayer buying for a large job often buys ahead of invoicing, and sometimes carries unused stock from one job into the next. For quarterly reporting, the question that arises is: when do you record the materials cost? HMRC's approach for sole traders is generally that materials are recorded as a business expense when purchased, not when used. But if you carry significant stock between quarters, your Q1 expenses may look higher than your Q1 income, and Q2 may look the reverse. This is normal and expected. Quarterly figures are not required to be balanced. The full-year view is what matters for tax.

Brick and material waste variance. Real-world bricklaying involves waste: cuts, breakages, mortar over-mix. Recording actual material costs (including expected waste) as a business expense is correct. You do not need to justify every brick; you need to record what you paid suppliers.

Seasonal gaps. Bricklaying income is genuinely weather-dependent. January and February can be months of enforced downtime on exposed sites. A quarterly income figure for Q3 (October to December) may be significantly lower than Q1. This is not a compliance problem. HMRC expects quarterly figures to be uneven across the year.

CIS deductions. If you work as a subcontractor under the Construction Industry Scheme and the main contractor deducts 20% at source, your income record for MTD purposes is your gross invoiced amount, not the net after CIS deduction. The CIS deduction you have suffered during the year is offset against your year-end tax bill. CIS is its own world of scheme rules, verification, and monthly statements. This post does not go deep on it. The point for MTD purposes is: record gross income, not net receipts.

A quarterly update reports income and expenses by category. The categories you will typically track on the expense side for a sole-trader bricklayer:

• Materials: bricks, mortar, sand, cement, lintels, wall ties, damp-proof course, fixings.
• Plant hire: mixer hire, scaffolding costs (if sub-hired, not purchased), hoisting equipment.
• Tools and small equipment: trowels, levels, bolsters, lines. Items replaced regularly and below the capital threshold.
• Vehicle costs: van insurance, fuel, servicing, road tax. If you use HMRC's flat mileage rate (45p per mile for the first 10,000 miles, 25p thereafter), you record mileage rather than actual vehicle costs.
• Protective equipment (PPE): hard hats, steel-toe boots, hi-vis, gloves, dust masks, safety glasses.
• Insurance: public liability, employers' liability if you take on labour, tools and equipment cover.
• Subcontractor costs: if you pay labourers or other trades, their invoices are a business expense. If they are CIS subcontractors, you follow the relevant CIS deduction rules at that point.
• Professional fees: accountancy, any trade body memberships, professional indemnity if held.
• Phone and communications: the business proportion of your mobile and any site communication costs.
• Training and certifications: CSCS card renewal, first aid, any trade-specific qualifications.
• Bank charges: business account fees, any card processing costs.
• Software: accounting software subscriptions, invoicing tools.

You report quarterly totals for each category, not individual receipts. The paperwork stays in your records.

The tax year runs 6 April to 5 April. Under MTD ITSA, quarterly periods are fixed:

• Q1: 6 April to 5 July (submission deadline: 7 August)
• Q2: 6 July to 5 October (submission deadline: 7 November)
• Q3: 6 October to 5 January (submission deadline: 7 February)
• Q4: 6 January to 5 April (submission deadline: 7 May)
• Final declaration: 31 January of the following year

Ten minutes per quarter, once your system is set up, is a realistic time for the submission itself. The ongoing work is in keeping your income and expense records current, not in the quarterly filing act itself.

Cloud accounting software. Platforms such as Xero, QuickBooks, or FreeAgent at £12–£30 per month. They handle income recording, expense categorisation, mileage tracking, and MTD quarterly submissions natively. Best fit: bricklayers with higher turnover, VAT registration, or regular subcontractors on the books who want one system handling most of the financial administration.

Spreadsheet plus bridging software. You maintain your own spreadsheet recording income and expenses by category; bridging software (typically £30–£50 per year) submits the quarterly totals to HMRC in the MTD-compliant format. Best fit: bricklayers with simpler finances, sole-trader operations with clear categories, and those already comfortable maintaining their own records.

Hand it to your accountant. Your accountant manages the quarterly submissions from the records you supply. The incremental cost for quarterly submissions may be reasonable if they already handle your year-end. The catch: your accountant can only submit what you have recorded. You still need to maintain digital records between meetings. Handing everything over in January will not work on a quarterly schedule.

There is no single right answer. The right tool depends on your transaction volume, your VAT position, and how much of this you want to own yourself.

If your records are currently informal (cash jobs noted loosely, materials receipts gathered approximately, a spreadsheet started and abandoned in February), the April 2026 deadline is the hard reset.

1. Separate business and personal money completely. A dedicated business bank account and card make every quarterly step faster and eliminates the most common source of errors.
2. Choose your approach now. Cloud accounting, spreadsheet plus bridging, or accountant-managed. Set it up before the first quarterly period begins.
3. Establish your expense categories consistently. Consistent categorisation from day one of Q1 is easier than restating categories mid-year.
4. Record all cash income as it arrives. Every cash payment is income in the period received. A simple log is sufficient. The discipline is the point.

If you do nothing else before April: open a dedicated business account and start recording every payment the same week it arrives. Everything else cascades from that.

The worst route is no route. HMRC's MTD penalty system accumulates points for missed quarterly submissions, leading to financial penalties once the threshold is reached. The penalties apply whether you are unaware of the requirement or simply delayed.
