Your online shop started small: a few orders a week from a spare room, packed between school runs, caring responsibilities or a part-time job. Then it grew — Etsy orders, a few from Amazon, and steady sales from your own website. Growth is good news, but it brings a question many women-led stores only meet when it is almost too late: when do I have to register for VAT?
The answer is not “when you feel like a proper business” or “at the end of the tax year”. It is a single number, checked over a rolling twelve months, with a short deadline. Get it wrong and you can owe VAT on sales already made, at prices that never included it.
Short answer: In 2026/27, a women-led online store must register for VAT once taxable turnover passes £90,000 in any rolling 12 months, or it expects to pass £90,000 in the next 30 days. Register within 30 days of the end of the month you crossed the threshold. Marketplace, website and all other taxable sales count towards the same total.
This guide explains the threshold, shows how to count sales across every channel, works through a £ example, and ends with a simple half-hour monthly check.
When does an online store have to register for VAT?
VAT registration is triggered by turnover, not by profit, and not by how your business is set up. Whether you are a sole trader selling from home or a limited company with a small studio, the same £90,000 threshold applies in 2026/27. You must register if either of these happens:
- Your total taxable turnover for the last 12 months goes over £90,000.
- You expect your taxable turnover to go over £90,000 in the next 30 days — for example, because a large wholesale order or a Christmas surge is already booked.
If you crossed the threshold by looking back over the last 12 months, you must register within 30 days of the end of that month, and registration takes effect on the first day of the second month after that. If you register because you expect to cross it soon, you must register by the end of that 30-day period, and your effective date is the date you realised you would cross it. You can also register voluntarily below £90,000, and if turnover later falls below £88,000, you can ask HMRC to cancel. For the full rules, see our guide to VAT registration in the UK.
How to count the £90,000 threshold for an online shop
The most common mistake is counting the wrong number. The threshold is based on taxable turnover — the total value of everything you sell that is not exempt or out of scope. That is not your profit, and it is not what is left after fees, postage or stock costs.
| Counts towards the £90,000 | Does not count |
|---|---|
| Standard-rated sales (20%), such as adult clothing and candles | Exempt sales, such as some financial services |
| Reduced-rated sales (5%), such as some energy-saving products | Sales out of scope of UK VAT |
| Zero-rated sales, such as most food and children’s clothing | Money that is not a sale, such as a family loan |
| Postage charged to the customer as part of the sale | Refunds actually given, which reduce the total |
| Sales through every channel added together | Marketplace fees paid — a cost, not a reduction in sales |
Two points surprise most sellers. First, zero-rated sales still count towards the threshold, even though no VAT is charged on them — a children’s clothing shop can cross £90,000 without ever charging VAT. Second, refunds reduce the total only once actually given. Keep a rolling 12-month total, not a calendar-year total: each month, add the new month and drop the month from a year ago. A huge December can therefore trigger registration in January, even if January was quiet.
Etsy, Amazon and your own website: add every channel together
Many women-led stores sell in three places at once: Etsy for discovery, Amazon for reach, and their own website for the best margin. For VAT, HMRC does not care which channel made the sale — taxable turnover is the total across all of them. That is where shops get caught: a seller who checks only her website might think she is at £60,000, while Etsy and Amazon sales take her true total to £95,000, and the 30-day clock is already running. Being on a marketplace does not register you for VAT, and it does not take over your duty if you are a UK-based seller. Fees, advertising and commission are business costs — they do not reduce taxable turnover. Once a month, note each channel’s taxable sales, add them together, and update your rolling total. Keep standard-rated and zero-rated goods separate in your records, but add them together for the threshold test.
Worked £ example: a candle shop crosses the threshold
Imagine Sara, who runs a home-based candle shop on Etsy and her own website. Her taxable sales over twelve months look like this:
| Month | Taxable sales |
|---|---|
| November | £6,900 |
| December | £9,400 |
| January | £7,200 |
| February | £6,800 |
| March | £7,600 |
| April | £7,900 |
| May | £8,100 |
| June | £7,400 |
| July | £7,800 |
| August | £7,500 |
| September | £8,200 |
| October | £8,700 |
| Total | £93,500 |
At the end of October, Sara’s rolling 12-month total is £93,500 — over the £90,000 threshold. She must register within 30 days of the end of October, so by 30 November, and her registration takes effect on 1 December.
From 1 December, Sara must charge VAT on standard-rated sales. A candle sold for £30 including VAT contains £30 × 20 ÷ 120 = £5.00 of VAT: Sara keeps £25 before her costs, and £5.00 belongs to HMRC, less VAT reclaimed on business purchases. Selling 300 candles in December at £30 gives VAT-inclusive sales of £9,000, with £1,500 of VAT inside them. Reclaiming £240 of VAT paid on packaging and supplies leaves £1,260 to pay HMRC for December. That is why price matters: keep the price at £30 and she absorbs the VAT; raise it to £36 and the customer pays it, but some may buy less. Many shops test a small rise before registration rather than taking a sudden 20% margin cut.
Voluntary registration: when registering early helps
You do not have to wait until £90,000 — voluntary registration can help, but it is not right for everyone.
| Voluntary registration helps when | It probably does not help when |
|---|---|
| You buy much VAT-chargeable stock or equipment and can reclaim the VAT | Most customers are shoppers who cannot reclaim VAT, so higher prices may lose sales |
| Your main customers are VAT-registered businesses who can reclaim your VAT | Sales are mostly zero-rated, so there is little VAT to reclaim or charge |
| You want to look established to wholesale or trade buyers | Turnover is far below £90,000 and admin time is already stretched |
| Your accountant advises it because your input VAT is large | You sell low-margin goods and cannot raise prices |
One warning: voluntary registration is not free admin. Once registered, you must file VAT returns, usually quarterly, using Making Tax Digital compatible software. Only register early if the reclaimable VAT or trade advantage clearly outweighs that work.
What changes the day you become VAT-registered
Registration changes how you price, invoice and file. First, you get a nine-digit VAT number, which must appear on every VAT invoice. Do not add VAT to invoices until registration is effective and you have that number; meanwhile, you may raise prices to cover the VAT you will owe. Second, decide prices before your effective date: absorb the VAT, pass it to the customer, or mix the two. Third, you start filing VAT returns, normally quarterly. You can reclaim VAT on business purchases only with a proper VAT invoice, so keep stock, packaging and software invoices in one place. Fourth, check shop settings: your website, Etsy and Amazon listings should show consistent prices, and your software must use the right rate per product type. Finally, consider the Flat Rate Scheme, open to turnover up to £150,000: it lets you pay a fixed percentage of VAT-inclusive turnover, depending on your trade, with limited-cost traders paying 16.5%. Take advice before switching.
Five mistakes women-led online shops make with VAT
- Counting only one channel. Etsy alone looks safe; all channels together may already be over £90,000.
- Waiting until the end of the tax year. The test is rolling, month by month — a December surge can trigger registration in January.
- Thinking the £1,000 trading allowance covers VAT. It is an Income Tax relief; it does not change the VAT threshold.
- Forgetting zero-rated sales. Children’s clothes and most food are zero-rated, but they still count towards £90,000.
- Registering late. You must pay VAT back to the date you should have registered, plus a possible penalty.
A 30-minute monthly VAT check
Set one recurring date each month and run through this list:
- Write down last month’s taxable sales from each channel: website, Etsy, Amazon and anywhere else.
- Add them to your rolling total and check it against £90,000. Within £10,000, start planning registration now.
- Note refunds given and large orders expected in the next 30 days.
- File the month’s purchase invoices for a future VAT return.
- If already registered, check your return deadline is in the diary.
Thirty minutes a month is a small price for avoiding a backdated bill — and it gives you a clear picture of how fast your shop is really growing.
Frequently Asked Questions
Do I need VAT registration if I only sell on Etsy?
Yes, if your total taxable turnover passes £90,000 in a rolling 12 months, even if every sale was on Etsy. Selling through one marketplace does not exempt you, and the marketplace does not register you. Add your Etsy sales to any other channel’s sales for the threshold test.
Does the £1,000 trading allowance mean I do not need VAT?
No. The £1,000 trading allowance can reduce the Income Tax you pay on small amounts of trading income, but it has no effect on VAT. VAT registration depends only on taxable turnover passing £90,000, or expecting to pass it in the next 30 days.
Can I register for VAT voluntarily below £90,000?
Yes. Voluntary registration lets you reclaim VAT on business purchases and can help with trade buyers, but it also means quarterly VAT returns and VAT on your prices. It is worth it mainly when your reclaimable VAT is large or your customers are VAT-registered businesses themselves.
What if my sales fall below £88,000 after I register?
You can ask HMRC to cancel your registration if your taxable turnover falls below £88,000, unless you are based outside the UK and supply goods or services to the UK. You must cancel within 30 days if you stop being eligible, or you may face a penalty. Check the current rules on GOV.UK’s guide to registering for VAT before you apply to cancel.
Conclusion
VAT registration is not a punishment for growing — it is a sign your shop has reached a real milestone. The £90,000 threshold, the rolling count and the 30-day deadline are manageable once you know them, and a half-hour monthly check keeps them from becoming a surprise. This week, add up your last twelve months of taxable sales across every channel. Near £90,000, start your price and registration plan now; far below it, keep the check going and grow knowing exactly where the line is.
