Question 1

When do I have to register for VAT?

Accepted Answer

When your VAT-taxable turnover exceeds £90,000 in any rolling twelve-month period, or when you expect to exceed it in the next thirty days alone. The rolling test is the one that catches people: it is not your tax year or your accounting year, it is any twelve consecutive months, so you have to check it monthly rather than annually. Once you cross, you have thirty days from the end of the month in which you crossed to register, and registration takes effect from the first day of the month after that. The forward-look test is different and bites immediately — if you sign a contract that alone will take you over £90,000 within thirty days, you must register at once. Late registration means paying over the VAT you should have charged, whether you charged it or not.

Question 2

Should I register for VAT voluntarily?

Accepted Answer

It depends almost entirely on who your customers are. If you sell to VAT-registered businesses, registering is often free money: they reclaim the VAT you charge so your price is effectively unchanged, while you start reclaiming VAT on your own costs. If you sell to the public, it is a 20% price rise you either absorb or pass on, and neither is comfortable. So a contractor working for developers should probably register; a mobile hairdresser should probably not. Secondary considerations: registration adds a compliance burden and puts you into MTD for VAT immediately, and it makes you look larger, which matters in some markets. The trap is registering for credibility and then discovering your margin has quietly dropped by a fifth.

Question 3

When are VAT returns and payments due?

Accepted Answer

One month and seven days after the end of your VAT period, for both the return and the payment. So a quarter ending 31 March is due by 7 May. Most businesses file quarterly on a stagger HMRC allocates at registration, and you can ask to change the stagger to align with your year end, which is worth doing. If you pay by direct debit, HMRC collects three working days after the deadline, which quietly buys you a little more time. The annual accounting scheme replaces this with one return a year and interim payments on account, which suits businesses with steady turnover and poor appetite for quarterly admin. Filing and payment penalties are separate, and paying late is the more expensive of the two.

Question 4

What is the flat rate scheme and should I use it?

Accepted Answer

The flat rate scheme lets you charge VAT normally but pay HMRC a fixed percentage of your gross turnover instead of the difference between output and input tax, and you generally cannot reclaim VAT on purchases. It exists to simplify, not to save, though it sometimes does both. It works for service businesses with few costs — a consultant with a laptop and a phone. It works badly for anyone with significant VAT-bearing purchases, because the input tax you forgo exceeds the saving. The limited cost business rules push businesses with low goods spend onto a high percentage that removes most of the benefit, and they catch more people than expected. Worth modelling on your actual figures rather than assuming; we can run it in an afternoon.

Question 5

What VAT can I reclaim, and what can I not?

Accepted Answer

You can reclaim VAT on goods and services bought for business purposes where you hold a valid VAT invoice and the supply was standard or reduced rated. The exclusions are what matter. Business entertainment is blocked almost entirely. Cars are blocked unless there is genuinely no private use at all, which in practice means pool cars and little else — vans and commercial vehicles are fine. Anything relating to exempt supplies is blocked, and if you make both taxable and exempt supplies you are partially exempt and only get a proportion. Private use must be apportioned. The most common error we correct is reclaiming on a purchase with no valid VAT invoice: a card receipt is not sufficient, and "the supplier is registered" is not the test.

Question 6

What is the difference between zero-rated, exempt and outside the scope?

Accepted Answer

They look similar on an invoice and behave very differently. Zero-rated supplies are taxable at 0% — most food, children's clothes, books, new residential construction — and because they are taxable you can still reclaim input VAT, which is why a zero-rated business often reclaims more than it pays. Exempt supplies, such as insurance, most financial services, health services and much of education, are outside the tax entirely and carry no right to reclaim related input tax. Outside the scope means the transaction is not a VAT supply at all — wages, dividends, most grants. The consequences are real: zero-rated turnover counts towards the £90,000 registration threshold, exempt turnover does not, and getting this wrong distorts both your returns and your registration position.

Question 7

What happens if I make a mistake on a VAT return?

Accepted Answer

Small errors can be corrected on your next return; larger ones must be disclosed to HMRC separately. The threshold turns on the net value of the error and your turnover — below the limit, adjust the next return and keep a record of what you changed and why. Above it, or where the error was deliberate, it needs a formal disclosure. Deliberate errors must always be disclosed regardless of size. Penalties depend far more on behaviour than on amount: a careless error disclosed unprompted attracts a much lower penalty, often nil, than the same error found by HMRC first. So the instinct to quietly bury a mistake is exactly backwards. Interest runs on underpaid VAT from the original due date either way.

Question 8

Can I reclaim VAT on things I bought before registering?

Accepted Answer

Yes, within time limits, and it is regularly missed. For goods you still hold at registration — stock, equipment, tools, a laptop — you can reclaim VAT on purchases made in the four years before registration, provided they were bought by the same legal entity for business purposes and you still have them. For services, the window is six months before registration. The goods must still be on hand: you cannot reclaim on stock you already sold. This gets forgotten because it lives on the first return, at the exact moment a newly registered business is most preoccupied with getting the basics right, and there is no prompt to remind you. For a business that has been trading a while before crossing the threshold, it can be a meaningful sum.

Question 9

What is the domestic reverse charge and does it affect me?

Accepted Answer

It affects you if you work in construction and supply another VAT-registered business that is CIS-registered and is not the end user. Under the reverse charge you do not charge VAT on your invoice; instead the customer accounts for it. Your invoice says the reverse charge applies and states that the customer must account for the VAT. It exists to stop missing trader fraud, and it has a significant side effect: subcontractors who previously enjoyed holding VAT until quarter end lose that cash flow, and many end up in a repayment position, which is a good reason to consider monthly returns. The end user question is the one that causes disputes — if your customer is the final consumer of the work, normal VAT applies and you should get their confirmation in writing.

Question 10

What happens if I file or pay my VAT return late?

Accepted Answer

Late filing earns a penalty point rather than an immediate fine, with a financial penalty once you reach the threshold for your filing frequency, and points expiring after a run of on-time returns. Late payment is charged separately and escalates with time: nothing if you pay or arrange a time-to-pay within a short grace window, then a first penalty, then a further penalty that accrues daily, with interest running throughout from the due date. The design is deliberate and worth reading the right way — filing late is cheap, paying late is not. So if you cannot pay, file anyway and ring HMRC about a time-to-pay arrangement. They are markedly more accommodating to a business that has filed and cannot pay than one that has simply gone quiet.
