About this episode

In this episode, we explain how VAT in the UK works and why it matters for businesses of all shapes and sizes. Whether we are running a sole trader business, limited company, charity, not-for-profit, or growing organisation, VAT can affect how we price, invoice, record, and report our sales.

We look at what VAT is, when businesses need to register, how VAT returns work, and which common VAT schemes may help with admin and cash flow management. We also cover practical VAT mistakes to avoid, including late registration, missed deadlines, incorrect claims, and poor record keeping.

What is VAT in the UK?

VAT stands for Value Added Tax. It is one of the most common taxes in the United Kingdom and applies to many goods and services. Unlike profit-based taxes, VAT follows its own set of rules, which means it can catch business owners out if they do not understand how it works.

VAT is collected by VAT-registered businesses from customers and then paid over to HMRC. In simple terms, a VAT-registered business acts as an unpaid tax collector and administrator for the government. If we do it correctly, it becomes part of normal business compliance. If we get it wrong, it can become expensive and stressful.

For most goods and services, the standard VAT rate is 20%. However, some items have a reduced rate of 5%, some are zero-rated, and some are exempt or outside the scope of VAT. This is why VAT rules need care, especially when pricing, invoicing, and claiming VAT back.

Why VAT matters for business owners

VAT matters because it affects cash flow, pricing, bookkeeping, compliance, and financial control. It is not money that belongs to the business. Once VAT is collected from customers, it should be set aside and paid to HMRC when due.

For small business finance UK, this is a key discipline. If VAT is treated as spare cash, a business can quickly run into problems when the VAT return is due. Good records, good systems, and clear processes help reduce mistakes and avoid unnecessary penalties.

VAT also matters because failing to register on time, charging VAT incorrectly, or missing filing deadlines can result in penalties and interest. Understanding VAT is therefore an important part of tax for small businesses and wider profit and financial control.

When do businesses need to register for VAT?

A business must register for VAT when its taxable turnover goes over the VAT threshold in any rolling 12-month period. The episode explains that this is not based on a calendar year or tax year. It is an ongoing calculation that business owners need to monitor throughout the year.

Businesses can also choose to register voluntarily, even when turnover is below the threshold. This can be useful if customers are VAT-registered businesses, because VAT can often be reclaimed on eligible expenses. However, voluntary registration should still be considered carefully, because it brings extra admin, VAT invoices, record keeping, and filing responsibilities.

How VAT works for businesses

Once registered, a business charges VAT on applicable sales. This is known as output VAT. It may also pay VAT on eligible business purchases, known as input VAT.

Usually, the business submits a VAT return to HMRC and pays the difference between VAT collected and VAT paid. For example, if a business charges £200 in VAT to a customer and pays £80 in VAT to a supplier, the difference of £120 is paid to HMRC.

If the business pays out more VAT than it collects, it may receive a VAT refund. However, HMRC can ask for evidence, so detailed records of sales, purchases, invoices, and VAT treatment are essential.

Common VAT schemes

Flat Rate Scheme

The Flat Rate Scheme allows eligible businesses to pay VAT as a fixed percentage of gross turnover based on their industry classification. This may simplify administration, especially for businesses with relatively low expenses.

Cash Accounting Scheme

The Cash Accounting Scheme can help cash flow because VAT is paid when customers pay, rather than when the invoice is issued. However, VAT on purchases can also only be claimed when suppliers are paid.

Annual Accounting Scheme

The Annual Accounting Scheme allows businesses to make instalment payments during the year and submit one VAT return annually. This may help with planning, although it will not suit every business.

Different industries may also have their own VAT schemes, such as margin schemes. The right scheme depends on the business model, industry, customer base, and cash flow position.

Common VAT mistakes to avoid

VAT mistakes can happen easily, especially when bookkeeping is not kept up to date. The episode highlights several common problems that business owners should avoid.

• Registering for VAT late after crossing the threshold.
• Forgetting to charge VAT once registered.
• Claiming VAT on items that do not qualify.
• Missing VAT return deadlines.
• Failing to keep proper VAT records.
• Using VAT collected from customers as normal business cash.
• Not checking VAT rules for online or international sales.

Using accounting software can make VAT tracking easier. If we need support with VAT tracking, invoicing, digital records, or Making Tax Digital, our Xero accounting support can help businesses stay more organised and compliant.

VAT and online sales

VAT rules can become more complex when a business sells online or deals with international customers. Sales through platforms, services outside the UK, and post-Brexit rules can all affect how VAT applies.

The key message is to check the rules before assuming VAT does or does not apply. If we sell online, use platforms, or work with international customers, proper advice and accurate records are especially important.

What happens if VAT is not paid?

If VAT returns are not submitted or VAT is not paid, HMRC can charge penalties and interest. It may also inspect business records if there are concerns.

If a business is struggling to pay VAT, the worst thing to do is ignore the issue. HMRC may still consider payment arrangements, but VAT is often treated seriously because the business has already collected that money from customers.

Practical steps for staying compliant with VAT

• Monitor taxable turnover on a rolling 12-month basis.
• Register for VAT on time when required.
• Set aside VAT collected from customers.
• Keep clear and accurate digital records.
• Use suitable accounting software for VAT tracking.
• Check whether a VAT scheme could reduce admin or support cash flow.
• Set calendar reminders for VAT deadlines.
• Speak to an accountant before making assumptions about VAT treatment.

VAT, Value Added Tax, or Very Awkward Tax, is the topic of this week's I Hate Numbers. I'm going to be looking at what it is, how it works, and how you can stay on top of it. Now this is a topic that crosses all types of business. So whether you're a sole trader, a limited company, a not for profit, a charity organisation, matters not.

VAT is a tax that is not profit-based. It has a completely different set of rules. In theory, it's quite straightforward. In practice, it can be a bit of a nightmare.

Now, VAT is one of the most common taxes in the United Kingdom. It raises an eye watering number of billions of pounds for the exchequer. Ultimately, it's the individual or business that's not registered for VAT that ends up paying the burden. Everybody else that's registered, more of that in a few moments, is acting as the tax collector or the administrator for VAT.

Now VAT, as I said, is one of the most common taxes in the UK, but also in my experience of three decades plus, is also one of the most misunderstood. Now whether you're just starting out or already running a business, knowing how VAT works will save you money, save you stress, and save you potential penalties.

Who wouldn't want that? By the end of this week's episode, you'll have an understanding of what VAT is, when you need to register, how to charge it, and most importantly, how to avoid those common trip hazards of VAT. Let's crack on. Firstly, what is VAT? We know it stands for value added tax. It came into being in the United Kingdom when we joined the European Community back in 1971.

Even though at time of recording this podcast we're no longer part of the European Union, the tax largely remains as it was when we were members of the EU. Now VAT is a tax on most goods and services sold or supplied to give it its proper meaning in the United Kingdom. Businesses collect it from their customers and pass that on to HMRC.

They are allowed to offset or deduct VAT they paid out of supplies that's allowable. In essence, your business acts as the role as unpaid tax collector and administrator for the government. There's no holiday pay, there's no remuneration. If you do it well, that's what you should be doing. If you do it wrong, then we don't want that situation to occur because it can be, at minimum, financially painful.

Now that is typically charged at 20 percent. That's called a standard rate on most goods and services, but there are exceptions. So things like energy bills, certain health products attract a lower rate of 5%. A rate of zero covers essentials like food, in the main, children's clothing and books. They're VATable, as they're called, but the rate charged is zero.

Now some items, some services, are outside of the scope of VAT, so things like paying wages and dividends, and some things, like financial services and rent, are exempt from VAT altogether. Now, as a handy tip, just because something is VAT free doesn't mean you can ignore it. Some transactions are zero rated, but you still have to report them if you're VAT registered, but you just don't charge the VAT.

It also affects the VAT that you can claim back. Number two, when do you have to register for VAT? Now, there are two rules here. There's a you must do it, and there's a situation where you can volunteer to do so. Let's look at this statutory when you have to. Now if you're taxable turnover, that's the sales that will be subject to VAT of either zero, five percent or twenty percent, go over 90,000 pounds in any rolling 12-month period, you must register for VAT.

Now this isn't based on tax years or calendar years, it's on a 12 month line in the sand. So theoretically, if you started your business on the 1st of January, you monitor your sales as you go through at the end of three months, your total turnover is 40,000, nothing to worry about. By the time nine months goes by, you've exceeded that 90,000 pounds.

You've hit the threshold. You need to register accordingly. It's an ongoing calculation and too many business owners, in my experience, fall foul of not registering for VAT and end up being late. That means, as you can guess, folks, penalties and interest. Now, failing to register on time usually leads to penalties and interest on the overdue tax.

So please make sure you keep an eye on your sales and turnover. Now, as I said, you can register voluntarily if your turnover is below 90,000. Useful if your clients are businesses that are registered for VAT because it ends up not only will you be able to claim VAT back on your expenses, but it ends up you tend to make larger profits.

Now one key tip here, make sure your business tracks the sales carefully. Certainly this is where digital accounting comes in useful because it can help you see what's going on under the bonnet of your business. The third thing I want to look at is how VAT actually works for businesses. Now once you are registered your business will charge VAT on goods and services that are applicable,

what we call output VAT. It will pay VAT out on purchases which is called input VAT. And typically every quarter, it reports the difference between those two numbers to HMRC via the VAT return. So for example, if I Hate Numbers, invoice to client for tax work of a thousand pounds and added VAT, that's 1200 pounds on the invoice, 200 pounds of that belongs to HMRC.

Now to run that business, I Hate Numbers, pays a supplier 400 pounds and they, the supplier charges them 80 pounds VAT. What that means is if nothing else goes on, 200 pounds has been charged to the customer. 80 pounds has been paid to the supplier. 120 pounds has to be paid over to HMRC with a VAT return.

Now, if it works the other way round, there's no income, but you're still paying VAT to your suppliers, then you get a refund of that money. Now the tip is here it’s also a statutory requirement, but make sure you keep detailed records of all that related transactions. HMRC can and does ask for proof of purchases, sales, and to make sure everything complies with the VAT rules.

The next thing I want to examine is VAT schemes that exist to simplify your life. Now, HMRC offer a variety of schemes. This is not an exhaustive list, but a sample. There's something called a flat rate scheme, which means that you pay a percentage based on your industry classification of the gross turnover as VAT.

It means you can't claim back VAT on purchases normally, and that might be sensible for a business that's got low level of expenses. A second type of scheme is called a cash accounting scheme. Now if you've got customers that take time to pay their bills, charging them VAT and paying it over before you've been paid can be a disadvantage to you, certainly it can harm your cash flow.

Under cash accounting scheme, you only pay VAT when you get paid from your customer, but also remember, you can only claim VAT when you pay your supplier. But that can be really advantageous with cash flow. There's also something called the annual accounting scheme. Now what that says is you figure out an amount that you owe, you pay that in installments through the year, and you do one VAT return per annum.

Now other schemes exist for different industries, so if you're in the car trade, you're selling goods under what's called a margin, you can operate what's called a margin scheme. Again, rules and regulations exist, and today is about making you aware of what's out there. Now one handy tip here is make sure you or your advisors choose the appropriate scheme for you, for your business, for the nature of what you do to save you money and reduce that admin work.

I now want to move into those common mistakes that can occur in VAT and they will occur, and how we can avoid them or do our best to do so. Now in 30 years of experience of working with businesses of varying sizes and complexities, having helped thousands of businesses, there's a few things that crop up.

Now, one I mentioned earlier is late VAT registration. People go over the threshold, don't realize that, especially when clients are doing their own bookworking. Now remember, if you're late registering the VAT, then you will be fined normally, a penalty, and interest. So don't delay registering for the VAT.

You do have a 30-day window on which to register. So in theory, there is time there. It's not unusual, some people, some businesses may forget to charge VAT in the first place. Now, if you're VAT registered, if you're a retailer, typically you're setting B2C and all your prices typically will include VAT.

Unless the items you're selling are zero rated or exempt. So make sure that you've considered the impact on your own pricing. If an item is marked up at 12 pounds, then within that two pounds that is VAT that doesn't belong to you. It belongs to HMRC. Other common mistakes include incorrectly claiming VAT that you think you're entitled to.

You can only claim VAT on business expenses, not personal ones. Certain items do not have VAT on them, so typically if you buy a train ticket, buy postage stamps, there's no VAT on those items. The other common mistake here, again all rectifiable, is to miss the VAT deadlines. Now late anything in the tax world means typically penalties and interest charges.

Now we're using whether it's Google Calendar, Outlook, or any other similar devices, set deadlines in your calendar, or see if your accountants have got something they can use to give you those reminder deadlines. In my own practice, we've got technology that we harness into to send those reminder dates out to clients.

Let's have a look at another area now, VAT and online sales. Now, especially when you've got international customers, online or otherwise, the VAT rules can get a little bit interesting. Now, once we left the EU, once Brexit happened, the EU is considered the rest of the world. Now, if you're selling through platforms like Amazon and eBay, the VAT in theory should be dealt with correctly and on behalf if you set things up correctly.

If you're providing services outside the UK, VAT may not necessarily apply, but there's some interesting complex rules which we'll pick up on a future podcast. If you do sell online, check the VAT rules for those international sales to avoid those unexpected bills, or speak to your accountant. What happens if you don't pay VAT? If you don't submit VA returns or pay what you owe, HMRC will charge penalties automatically interest, and even have that flank triggered where they inspect your business records.

Like all things in life, if you are struggling to pay, don't put your head in the duvet. Don't bury it. Contact HMRC. Please note though, they normally take the view with VAT more so that you've collected it already from customers. That money hasn't belonged to you. You’ve had an interest-free loan. So they tend to be less receptive to payment plans, but they still will agree them.

So what's my final concluding tips for business owners? Well, to help keep VAT manageable, keep clear records, good bookkeeping, not only is a statutory requirement, but it's an essential business discipline. It minimises mistakes. Set money aside for VAT. Don't spend the VAT you've collected. It doesn't belong to you.

You're merely using it on behalf of HMRC. It's an interest-free loan. So again, as soon as the money's received, put it aside, take it out of the system, take it out of the psychology and your consciousness. Now accounting software is going to be a mandatory thing, and from April 26th under Making Tax Digital, it's going to be more of a requirement until that kicks in.

Tools like Xero will make your VAT tracking much easier. Please check out the show notes, by the way, folks, for getting included on our soon to be released tax newsletter, and also if you need any support with digitisation and the like. And access an accountant. Whether you have an accountant with you all the time, that paid-for advice will return itself in saved stress, saved tax, and minimal mistakes.

Now that's a wrap this week on VAT. Hopefully you got some use out of it. If there's somebody in your network you think could benefit, I'd love it if you could share that podcast with them and encourage them to subscribe. And remember, numbers aren't scary when you know how to handle them.
