Do I Need to Charge VAT as a Self-Employed Tradesman? (2026)

1. The VAT registration threshold (£90,000 in 2026)

You must register for VAT when your taxable turnover exceeds £90,000 in any rolling 12-month period. This is not a calendar year — it is any 12 consecutive months. You must register within 30 days of the date you exceeded the threshold, or you risk penalties and backdated VAT liability.

"Taxable turnover" means the total value of your VATable sales — for most tradespeople, this is essentially all your invoiced income. It does not include exempt supplies (which are rare in the trades).

Watch the rolling 12 months

HMRC calculates your turnover on a rolling basis — not just your tax year. If you have a particularly busy 12 months that crosses two tax years, you can hit the threshold without realising it. Check your running total every month if you're approaching £90,000.

2. Voluntary VAT registration — pros and cons

Any business can register for VAT voluntarily, even if below the threshold. Whether this makes sense depends on who your customers are.

Reasons to register voluntarily

·Your customers are mainly VAT-registered businesses — they can reclaim the VAT you charge, so it costs them nothing extra
·You spend heavily on materials, tools, and equipment — reclaiming input VAT saves you real money
·It can signal to larger commercial clients that you are an established, professional operation
·You can register for the Flat Rate Scheme and potentially profit from the difference between what you collect and what you pay

Reasons not to register voluntarily

·Your customers are mainly domestic homeowners — they cannot reclaim VAT, so you either absorb the cost or become 20% more expensive
·Quarterly VAT returns add significant administrative burden
·You must keep detailed VAT records and file on time or face penalties
·Cash flow timing: you collect VAT from customers but pay it to HMRC quarterly — if you don't manage this carefully, you can get caught short

3. VAT on materials vs labour

If you are VAT registered, both your labour and the materials you supply to customers are subject to VAT at the same rate. For most trade work, this is 20% standard rate.

The key exceptions where different rates can apply:

·New residential builds: zero-rated (0%) on labour and qualifying materials
·Energy-saving materials (insulation, heat pumps, solar): 0% since April 2022
·Conversions of non-residential buildings to dwellings: 5%
·Work for disabled people: zero or reduced rate on specific items
·Renovation of empty properties (unoccupied for 2+ years): 5%

If you are unsure which rate applies to a particular job, check HMRC's VAT Notice 708 (Construction and Building) or ask your accountant before invoicing. Charging the wrong rate — even innocently — creates problems.

4. Domestic reverse charge for construction

Introduced in March 2021, the domestic reverse charge (DRC) is a significant change that affects subcontractors working within the construction supply chain.

DRC applies when:

·You are VAT registered AND supplying construction services
·Your customer is also VAT registered AND CIS-registered
·Your customer is not the end user of the building

Under DRC, you do not add VATto your invoice. Instead, the customer accounts for VAT themselves. Your invoice must state: "Domestic Reverse Charge: Customer to account for VAT to HMRC at 20%." You still show the net amount and the VAT rate that would apply — you just don't collect it.

DRC does not apply when you invoice:

·Domestic homeowners (private individuals)
·A business that is the end user and occupier of the building
·A customer who is not VAT registered

Cash flow impact

Under DRC, you no longer collect VAT from your contractor clients — which can significantly affect your cash flow if you were relying on the VAT you collected to fund your input VAT reclaims. Plan your VAT returns carefully.

5. How to show VAT on your invoices

A valid VAT invoice must include:

·Your VAT registration number (shown as 'VAT No: GB XXXXXXXXX')
·The invoice date and a unique sequential invoice number
·Your name, address, and the customer's name and address
·A description of the goods or services supplied
·The net amount (excluding VAT) for each line item
·The VAT rate applied to each line (20%, 5%, 0%, or 'exempt')
·The VAT amount charged
·The total amount including VAT

TraderInvoice automatically calculates and displays VAT correctly on every invoice — you just select the rate that applies and the figures are handled for you. No manual maths, no risk of showing the wrong amount.

Labour: Fit new radiator and TRV — £240.00

Materials: Radiator, TRV, fittings — £85.00

Net total: £325.00

VAT @ 20%: £65.00

Total due: £390.00

VAT No: GB 123 4567 89

6. Reclaiming VAT on tools and materials

Once VAT registered, you can reclaim the VAT on most business purchases. For tradespeople, this includes:

·Tools and equipment (power tools, hand tools, test equipment, ladders)
·Materials purchased for jobs
·Work van purchase or lease (subject to private use restrictions)
·Fuel for business travel (keep records)
·PPE, workwear, and safety equipment
·Business phone and associated costs
·Accountancy and professional fees
·Advertising and website costs

You must have a valid VAT invoice from your supplier to reclaim VAT. A receipt is not enough — it must be a proper VAT invoice showing the supplier's VAT number and the VAT amount.

VAT on items used partly for business and partly privately (such as a van or phone) can only be reclaimed proportionally. HMRC scrutinises this, so keep records of your business use.

7. The VAT Flat Rate Scheme for tradespeople

The VAT Flat Rate Scheme (FRS) is designed to simplify VAT accounting for small businesses. Instead of tracking the VAT on every individual sale and purchase, you pay HMRC a fixed percentage of your gross (VAT-inclusive) turnover.

You still charge customers 20% VAT as normal. The difference between what you collect and what you pay under FRS is yours to keep. Example flat rates for trades (check HMRC for current figures):

·Plumbers and heating engineers: approximately 9.5%
·Electricians: approximately 14.5%
·General building and construction: approximately 9.5%
·Roofers: approximately 9.5%

FRS works well if you have relatively low input VAT (e.g. labour-intensive work with few materials). If you buy a lot of materials and equipment, standard VAT accounting usually lets you reclaim more. The FRS also comes with a 1% discount in your first year of VAT registration.

To join the Flat Rate Scheme, your VAT-exclusive turnover must be £150,000 or less. You must leave if your gross turnover exceeds £230,000.

Limited cost trader rule

If less than 2% of your turnover (or less than £1,000/year) is spent on goods, you are classed as a "limited cost trader" and must use a flat rate of 16.5% — which largely removes the FRS benefit. This mainly affects labour-only subcontractors.

VAT calculated automatically on every invoice

TraderInvoice handles VAT, CIS, and payment terms automatically. Whether you're on standard VAT, the flat rate scheme, or working under the domestic reverse charge — your invoices are always correct.

8. Frequently Asked Questions

What is the VAT registration threshold for 2026?

The VAT registration threshold in 2026 is £90,000. If your taxable turnover exceeds £90,000 in any rolling 12-month period, you must register for VAT with HMRC. Once registered, you must charge VAT on your taxable supplies, file VAT returns (usually quarterly), and pay the VAT you collect to HMRC minus the VAT you have reclaimed on business purchases.

Can I charge VAT on both materials and labour?

Yes. If you are VAT registered, you must charge VAT on both your labour and the materials you supply to customers. Both are 'taxable supplies' and the standard rate of 20% applies to most construction and trade work. The key exception is if certain reduced or zero rates apply to the type of work being done (e.g. new residential builds, energy-saving materials, or work for disabled people). Materials you buy for your own use as a business expense can have their VAT reclaimed on your VAT return.

What is the domestic reverse charge for construction?

The domestic reverse charge (DRC) applies when a VAT-registered tradesperson provides construction services to another VAT-registered business. Instead of you charging VAT, the customer accounts for VAT themselves. Your invoice must NOT include VAT — instead, it must state 'Domestic Reverse Charge applies — customer to account for VAT to HMRC at [rate]%'. DRC does not apply when invoicing end users (homeowners or businesses that are the final occupier) — it only applies in the supply chain between VAT-registered construction businesses.

What is the VAT Flat Rate Scheme and is it worth it for tradespeople?

The VAT Flat Rate Scheme (FRS) lets you charge customers 20% VAT but pay HMRC a fixed percentage of your gross (VAT-inclusive) turnover instead of calculating the exact VAT on every purchase and sale. Flat rates vary by trade — plumbers are typically 9.5%, electricians around 14.5%. You keep the difference between what you collect and what you pay. FRS is simplest when your VAT on business purchases is low (e.g. mainly labour-only work). If you buy a lot of materials with VAT, you may be better off on standard VAT accounting so you can reclaim in full. Turnover must be under £150,000 to join.

Should I voluntarily register for VAT before hitting the threshold?

Voluntary VAT registration makes sense if: (1) most of your customers are VAT-registered businesses who can reclaim it, so VAT doesn't cost them anything extra; (2) you spend heavily on materials, tools, and equipment and want to reclaim that VAT; (3) you want to appear more established to larger commercial clients. It is generally a bad idea if most of your customers are domestic homeowners, because adding 20% to your prices makes you less competitive against non-VAT-registered competitors. Talk to an accountant before voluntarily registering.
