VAT for Tradespeople: A Simple Guide

VAT confuses a lot of tradespeople, and getting it wrong can cost you. Here's a plain guide to when you need to register, how to charge it, and what to watch out for.

VAT is one of those topics that every tradesperson eventually has to understand, whether they like it or not. Get it right and it's mostly paperwork. Get it wrong and you can end up with unexpected bills, penalties, or a nasty surprise from the tax office.

This guide explains the basics in plain English: when you need to register, how to charge VAT, and the common mistakes to avoid. It's general guidance only. Rules vary by country and change regularly, so always check with an accountant or your local tax authority before making decisions.

What VAT actually is

VAT (Value Added Tax) is a tax added to the price of goods and services. In most countries, once your business earns above a certain amount per year, you have to register for VAT, collect it from your clients, and pay it to the tax authority. You can also reclaim VAT on business purchases, which is the silver lining.

Not every business has to register for VAT. Below the threshold, you can trade without charging it at all, which keeps your prices lower for private clients.

Registration thresholds by country

• South Africa: compulsory VAT registration once annual turnover exceeds R1,000,000. Voluntary registration possible above R50,000.
• United Kingdom: compulsory registration once turnover exceeds £90,000 in a rolling 12-month period (check current figure before relying on this).
• Ireland: thresholds of around €40,000 for services and €80,000 for goods, subject to change.
• Australia: GST (their version of VAT) registration required once turnover exceeds AUD 75,000.

These figures change. Always check the current number with your local tax authority or accountant before acting on them.

Should you register voluntarily?

If you're below the threshold, you can often choose to register voluntarily. Whether that's worth it depends on who your clients are.

If you mainly work for businesses that are VAT-registered, registering voluntarily can make sense. They can claim back any VAT you charge them, so it doesn't cost them anything. Meanwhile, you can claim back VAT on your own purchases, like tools, a van, or materials.

If you mainly work for private homeowners, voluntary registration will make your prices look 15 to 20 percent higher overnight, because private clients can't reclaim VAT. That's usually a reason to stay unregistered as long as possible.

How to charge VAT on quotes and invoices

Once you're registered, every quote and invoice has to show VAT clearly. The standard layout is a subtotal (excluding VAT), the VAT amount as a separate line, and the final total including VAT, which a free VAT calculator works out for you in seconds, whether you start from a price that includes VAT or one that excludes it.

For private clients, show inclusive pricing prominently. For business clients, show both inclusive and exclusive prices so they can easily see what they can reclaim. Your invoice also needs your VAT number printed on it, along with the client's VAT number if you're selling cross-border within the EU or similar.

VAT-inclusive vs exclusive pricing

This is where tradies get confused. 'Inclusive' means VAT is already included in the price. 'Exclusive' means VAT is added on top.

If you quote a homeowner R10,000 inclusive of VAT, they pay R10,000 and you owe the tax office about R1,304 of that. If you quote them R10,000 exclusive of VAT at 15 percent, they actually pay R11,500. The difference matters. Always state clearly on your quote whether the prices include VAT or not.

VAT on materials vs labour

Once you're VAT-registered, you charge VAT on both labour and materials. You also reclaim VAT on the materials you bought, so the net effect is usually that VAT is only being charged on your labour portion, which is what the tax authority actually wants.

Some countries have reduced VAT rates for specific categories, like energy-efficient installations or certain renovation work on older properties. If you do that kind of work regularly, ask your accountant whether a reduced rate applies.

Keeping records for VAT returns

VAT-registered businesses have to file regular returns, usually every two or three months. The return shows how much VAT you charged clients and how much VAT you paid on purchases. You pay the difference to the tax authority (or receive a refund if you paid more than you charged).

That means every invoice you send and every receipt for a business purchase needs to be kept. Digital records are fine in most countries and are far easier to manage than paper. Most tax authorities now require digital records anyway as part of Making Tax Digital, SARS e-filing, or similar schemes.

Common mistakes to avoid

• Forgetting to include your VAT number on invoices
• Mixing inclusive and exclusive pricing on the same quote
• Not tracking turnover month by month and missing the registration threshold
• Claiming VAT back on personal purchases (a fast way to get audited)
• Losing receipts and under-claiming VAT on legitimate business costs

A decent quoting and invoicing tool handles most of this for you. QuoteGenio lets you set your VAT rate once into one of the free quote templates and automatically adds it to quotes and invoices, with your VAT number printed on every document.
