VAT Guide for UK Trade Businesses — Registration, Schemes, Returns and the Domestic Reverse Charge (2026)

VAT registration threshold 2026

You must register for VAT when your VAT-taxable turnover exceeds £90,000 in any rolling 12-month period. This threshold has been frozen at £90,000 since April 2024 and remains in place for 2026. It applies to your total VAT-taxable sales — not profit, not net invoiced amounts, but gross turnover before expenses.

You must monitor your turnover on a rolling 12-month basis, not just by tax year or calendar year. If your turnover in any 12-month window exceeds £90,000, you have 30 days to notify HMRC and your VAT registration takes effect from the end of that 30-day period. You can also register voluntarily once you know you are approaching the threshold.

Voluntary VAT registration

You can register for VAT voluntarily even if your turnover is below £90,000. For many trade businesses, this makes commercial sense:

• B2B work: if your clients are VAT-registered businesses, they can reclaim the VAT you charge them. Being VAT-registered does not make you more expensive to them — the VAT is neutral. It can also signal that you are a serious, established business.
• Reclaiming input VAT on materials and tools: once registered, you can reclaim VAT on everything you buy for the business — materials, tools, van running costs, equipment. For a trade business spending £30,000 a year on VAT-bearing goods, that is up to £6,000 of VAT back from HMRC each year.
• Pre-registration VAT: you can reclaim VAT on goods purchased up to four years before registration (if you still hold them) and services purchased up to six months before registration. This can be a useful one-off benefit when you first register.

The downside of voluntary registration is added admin: quarterly returns, MTD-compatible software, and the need to charge VAT to domestic (non-VAT registered) clients — who cannot reclaim it and will see a 20% price increase. If most of your clients are homeowners rather than businesses, voluntary registration can make you less price-competitive.

VAT rates that apply to trade work

Not all building and trade work is charged at the same VAT rate. Getting the rate wrong — in either direction — is one of the most common and costly VAT mistakes in the construction sector.

Standard rate: 20%

The standard rate of 20% applies to the majority of trade work: repairs, maintenance, refurbishments, extensions, loft conversions, most commercial construction, and any work on existing residential buildings. When in doubt, 20% is the default.

Zero-rated work: 0%

Zero-rated work is taxable at 0% — you still need to be VAT-registered and report it on your VAT return, but you charge the client nothing in VAT and can still reclaim input VAT on your costs. The main zero-rated construction categories for tradespeople are:

• New residential builds: construction of a new dwelling that has not previously been occupied. This applies to the entire build — groundworks, electrical, plumbing, roofing — provided the building will be used as a dwelling when complete.
• Certain conversions: converting a non-residential building (such as a barn or office) into a dwelling can be zero-rated. Converting a property from one dwelling into multiple dwellings also qualifies under certain conditions.

Developers and main contractors must provide evidence of zero-rating — typically a certificate from the client confirming the nature of the building. Subcontractors working on a new build can also zero-rate their supplies when they have a certificate from the main contractor confirming the work relates to a qualifying building.

Reduced rate: 5%

A reduced rate of 5% applies to certain energy-saving materials supplied and installed in residential properties. As of 2026, this includes:

• Heat pumps (air source and ground source)
• Insulation (loft, wall, floor and draught-proofing)
• Solar panels (photovoltaic and solar thermal)
• Wind turbines and micro-CHP units installed in residential premises
• Central heating and hot water system controls

The 5% rate applies to both the materials and the installation labour when supplied together as a single supply. If you supply materials only (without installation), the reduced rate may not apply. The residential restriction is important: commercial property installations are generally standard-rated at 20%.

VAT schemes for trade businesses

HMRC offers three simplified VAT schemes designed to reduce admin for smaller businesses. Each suits a different type of trade business.

Flat Rate Scheme (FRS)

The Flat Rate Scheme simplifies VAT by replacing input and output tracking with a single calculation. You charge clients 20% VAT as normal, but instead of tracking your input VAT and paying HMRC the difference, you pay a fixed percentage of your gross (VAT-inclusive) turnover to HMRC. The percentage varies by trade:

The FRS entry threshold is £150,000 net (ex-VAT) turnover. You must leave if gross (VAT-inclusive) turnover exceeds £230,000. New registrants receive a 1% discount in their first year. The trade-off: you cannot reclaim input VAT on routine purchases (only on capital assets costing £2,000 or more including VAT). FRS suits labour-heavy trades with low materials spend; it is less suited to trades with high materials costs.

Cash Accounting Scheme

Under standard VAT accounting, you account for output VAT on the invoice date — even if the client has not paid yet. This creates a cash flow problem: you owe HMRC VAT on money you have not received.

The Cash Accounting Scheme (CAS) solves this by letting you account for VAT on the date you receive payment rather than the invoice date. You also only reclaim input VAT when you actually pay your suppliers — not on receipt of their invoice.

The CAS threshold is £1.35 million net annual taxable turnover. You must leave if turnover exceeds £1.6 million. For trade businesses dealing with slow-paying clients or commercial customers on 60-90 day payment terms, cash accounting can significantly ease quarterly VAT cash flow pressure.

Annual Accounting Scheme

Instead of four quarterly returns, the Annual Accounting Scheme (AAS) lets you file just one VAT return per year. You make interim payments throughout the year — either nine monthly payments or three quarterly payments — based on an estimate of your annual VAT liability. The final return reconciles your actual liability against the payments made.

The AAS threshold is £1.35 million net annual taxable turnover. It reduces the admin burden of VAT returns to once a year, but interim payments must still be made on time. It is often combined with cash accounting for maximum simplicity.

Making Tax Digital (MTD) for VAT

Making Tax Digital for VAT has been mandatory for all VAT-registered businesses since April 2022. You must:

• Keep digital VAT records using MTD-compatible software
• Submit your VAT returns directly from that software via HMRC's API
• Maintain a digital audit trail — you cannot manually re-key figures into HMRC's portal

Compatible software used by trade businesses includes Xero, QuickBooks, FreeAgent, Sage, and a number of trade-specific job management platforms that have built-in VAT return submission. HMRC maintains a list of approved software on GOV.UK.

MTD applies whether you are on standard VAT accounting, the Flat Rate Scheme, Cash Accounting, or Annual Accounting. The requirement is about how you keep and submit records, not which VAT scheme you use.

Domestic Reverse Charge (DRC)

The Construction Services Domestic Reverse Charge (DRC) is a VAT anti-fraud measure that changed who accounts for VAT on certain construction supplies. It has been in force since 1 March 2021 and affects a significant number of trade businesses — particularly CIS subcontractors.

What the DRC means

Under normal VAT rules, the supplier charges VAT and pays it to HMRC. Under the reverse charge, the customer accounts for the VAT rather than the supplier. The subcontractor invoices without VAT, and the main contractor (or customer) accounts for both the output VAT (as if they charged themselves) and reclaims it as input VAT in the same return. The net VAT effect is zero for the customer — the purpose is to prevent fraudulent subcontractors collecting VAT from clients and disappearing without paying it to HMRC.

Which trades are affected

The DRC applies when all three of the following conditions are met:

1. The supply is of construction services as defined by HMRC (broadly, anything within the CIS scope)
2. Both parties are VAT-registered
3. The customer is not an end user (i.e. the customer is going to onward supply the construction services, such as a main contractor using a subcontractor)

Practically, this means DRC applies when a VAT-registered subcontractor works for a VAT-registered main contractor. It does not apply when you work directly for a homeowner, a business that is the end user of the work (e.g. a manufacturer building its own factory), or an unregistered client.

How to invoice correctly under DRC

If a supply is subject to the DRC, your invoice must:

• Show your net amount (labour and materials) but not add VAT
• State clearly: "Domestic Reverse Charge — customer to account for VAT at 20%"
• Show the VAT rate that would have applied (20% or 5%) and the amount of VAT the customer must account for
• Include both your VAT registration number and — where known — the customer's

A compliant DRC invoice for £5,000 of labour would say: net £5,000, VAT at 20% (customer to account for) £1,000, total £5,000. The customer pays you £5,000 — no VAT is collected. You do not include the £1,000 VAT in your VAT return output tax.

VAT on materials

When you buy materials for a job and include them in your invoice to the client, you are making a mixed supply — part labour, part materials. The VAT treatment follows the principal supply: if the overall job is standard-rated, both the labour and materials are standard-rated at 20%. If the job is zero-rated (new build), both elements are zero-rated.

You can reclaim input VAT on materials you purchase for business use, provided:

• You hold a valid VAT invoice from the supplier
• The materials are used for a VAT-taxable supply (not an exempt supply)
• You are on standard VAT accounting or cash accounting (not FRS, where the right to reclaim input VAT is surrendered)

For materials purchased in cash or from suppliers who do not issue VAT invoices, you cannot reclaim the input VAT. Always obtain a proper VAT receipt or invoice for materials — a till receipt that does not show the supplier's VAT number is not a valid VAT invoice.

VAT on commercial property

Commercial property is a complex area of VAT. By default, the sale or letting of commercial property is VAT-exempt — no VAT is charged and no input VAT can be reclaimed.

However, property owners can elect to opt to tax their commercial property. Once an option to tax is in place, the sale and rental of that property become VAT-taxable at 20%. This allows the owner to reclaim input VAT on costs related to the property (construction, refurbishment, maintenance).

For tradespeople working on commercial buildings:

• If the owner has opted to tax, construction and refurbishment work is standard-rated and DRC rules apply if you are a subcontractor
• If there is no option to tax and the work is for the property owner's own business use, the work is generally standard-rated (construction services are taxable — it is the property transaction itself that may be exempt)
• New commercial buildings are always standard-rated on first grant of a major interest, regardless of option to tax

If you are working on a commercial development and are unsure about VAT liability, ask the client or their solicitor whether an option to tax is in place and who is the end user.

Common VAT mistakes made by trade businesses

HMRC VAT enquiries into construction businesses frequently uncover the same errors. Avoid these:

• Charging 20% VAT on zero-rated new builds: if the client holds a qualifying new build certificate and the work is genuinely zero-rated, charging 20% is an error. The client has overpaid and you have overcollected — and HMRC will want the error corrected.
• Applying zero-rating without a certificate: conversely, zero-rating a supply without holding the correct documentation exposes you to the full VAT liability if HMRC challenges the zero-rating. Always obtain a written declaration from the client before applying a reduced or zero rate.
• Not registering on time: HMRC can assess VAT back to the date you should have registered. You will owe VAT on all taxable sales since that date — including amounts you did not charge clients. The cost comes out of your margin.
• DRC errors: failing to apply the reverse charge when required (and therefore incorrectly collecting and paying VAT) — or applying it when it should not apply (and leaving the client to sort out a VAT credit). Both create problems on both sides of the supply chain.
• Mixing FRS and standard VAT calculations: businesses on FRS who still try to offset input VAT against output VAT are making an error. You have given up the right to input VAT claims (except capital assets over £2,000) when you joined the scheme.
• Not keeping VAT invoices: without a valid VAT invoice, input VAT cannot be reclaimed. HMRC expects you to hold records for at least six years.

The 2023 VAT penalty regime

HMRC replaced the old default surcharge system with a new points-based penalty regime from January 2023. It works as follows:

• Each late VAT return earns you one penalty point
• Points expire after a period set by your filing frequency (24 months for quarterly filers)
• When you reach the penalty threshold — four points for quarterly filers — you receive a £200 fixed penalty
• Each subsequent late return while at the threshold adds another £200 penalty
• Late payment of VAT triggers separate late payment penalties: 2% of outstanding VAT after 15 days, rising to 4% after 30 days, then daily interest (at the Bank of England base rate plus 2.5%) after 31 days

To avoid penalty points: always file on time even if you cannot pay. You can set up a Time to Pay arrangement with HMRC to spread a VAT debt — this stops further late payment penalties accruing while you pay. Points are only cleared once you have filed on time for a continuous period matching your filing frequency (four quarters for quarterly filers).

VAT de-registration

You can de-register from VAT if your VAT-taxable turnover falls below £88,000 (the de-registration threshold, which sits £2,000 below the registration threshold). You must also de-register if you stop making VAT-taxable supplies entirely.

Before de-registering, consider the consequences:

• You will no longer be able to reclaim input VAT on purchases
• You must account for VAT on any business assets you retain at the date of de-registration (as if you had sold them at market value) if the total VAT exceeds £1,000
• De-registration can signal to business clients that your turnover has dropped significantly — some prefer to remain registered even when eligible to de-register

Apply to de-register online through your HMRC VAT account. De-registration takes effect from an agreed date — usually the date your application is approved or a later date you request. Keep all VAT records for at least six years after de-registration.

How Trade2Base helps VAT-registered trade businesses

For trade businesses approaching the £90,000 registration threshold — or already VAT-registered and wanting tighter control of their numbers — accurate revenue tracking is essential. The difference between forecasting £85,000 and £95,000 in the next 12 months determines whether you register voluntarily or are forced to register in a rush.

Trade2Base tracks revenue across every marketing channel — Google Ads, Checkatrade, referrals, organic search, direct bookings — so you can see exactly where your turnover is coming from and how it is trending month by month. For VAT-registered trade businesses, this means:

• Accurate rolling 12-month turnover data to monitor your position against the £90,000 threshold
• Channel-by-channel revenue visibility to spot which sources are driving growth (and whether that growth puts you in a new VAT band)
• Cleaner data for your accountant at VAT return time — less time reconciling, more time advising

Knowing your numbers in real time is the foundation of good VAT management. Trade2Base gives you that foundation.
