The Flat Rate VAT Scheme for Ecommerce: Is It Still Worth It?
If you run a small UK ecommerce brand and you're VAT-registered, the Flat Rate Scheme (FRS) has probably come up in conversation at some point. The pitch sounds appealing: less admin, a fixed percentage, and, for some businesses, a little extra margin baked in. But the reality for Shopify sellers and Amazon sellers is more nuanced than the headline suggests.
This guide walks through exactly how the Flat Rate Scheme works, whether it still makes sense for ecommerce product brands, and the specific scenarios where it helps versus where it quietly costs you money.
What Is the Flat Rate VAT Scheme?
Under the standard VAT scheme, the maths is straightforward: you collect 20% VAT on your sales, reclaim the VAT on your eligible purchases, and pay HMRC the difference. That means keeping careful records of every VATable expense, supplier invoices, import VAT, and platform fees, to make sure you're only paying what you genuinely owe.
The Flat Rate Scheme works differently. Instead of tracking VAT on individual purchases, you simply apply a fixed percentage to your gross (VAT-inclusive) turnover each quarter and pay that to HMRC. You still charge your customers 20% VAT as normal; the FRS only changes what you hand over to HMRC.
The percentage you use depends on your business sector. For most ecommerce product businesses, the relevant category is 'retail not listed elsewhere', which carries a flat rate of 7.5%.
A quick example: you sell £10,000 of goods (net) in a quarter. You charge customers £12,000 (including 20% VAT). On the Flat Rate Scheme at 7.5%, you pay HMRC £900 (7.5% × £12,000) instead of the standard £2,000 collected. The £1,100 difference is yours to keep , but you can't reclaim VAT on your purchases.
Who Can Join the Flat Rate Scheme?
Eligibility is based on turnover thresholds set by HMRC:
•Your expected VAT-exclusive taxable turnover must be £150,000 or less in the next 12 months to join.
•Once you're in, you can stay until your total VAT-inclusive income exceeds £230,000, at which point you must leave.
•You must already be VAT-registered (the mandatory registration threshold is £90,000 of taxable turnover).
That means the FRS is specifically designed for smaller, earlier-stage ecommerce businesses, those doing roughly £90k to £190k in revenue (VAT-exclusive) where the simplicity argument is strongest.
The Thing That Changes Everything: The Limited Cost Trader Test
Here's where many ecommerce founders get caught out. In 2017, HMRC introduced the Limited Cost Trader (LCT) test , a rule designed to stop service businesses with almost no costs from benefiting unfairly from the scheme.
The test asks: how much does your business spend on relevant goods each quarter?
You are classified as a Limited Cost Trader if your spending on relevant goods (including VAT) is:
•Less than 2% of your VAT-inclusive turnover for the quarter, OR
•More than 2%, but less than £250 in that quarter (the pro-rated annual figure of £1,000)
If you're a Limited Cost Trader, your flat rate jumps to 16.5% , regardless of your sector. At 16.5% of VAT-inclusive turnover, you're effectively paying 19.8% on your net sales. That leaves almost nothing from the VAT you collect, which makes the FRS virtually pointless.
The test applies every single quarter. You could pass in one period (because you made a large stock purchase) and fail in the next. You need to check each time you file your VAT return.
What counts as 'relevant goods'?
This is the critical detail. For the LCT test, HMRC's definition of relevant goods is deliberately narrow. The following do NOT count:
Services of any kind, so your Amazon PPC spend, Shopify subscription, fulfilment software, accountancy fees, and Canva subscription are all excluded
Capital assets, laptops, equipment, cameras
Vehicles and fuel (unless you're a transport business)
Food and drink purchased for you or your staff
Anything bought and intended to be given away
What does count: physical stock you buy to resell, packaging materials, and similar tangible goods used directly in your business.
For a product ecommerce business buying physical inventory, this is where the calculation gets interesting, and more favourable than it would be for, say, a consultant or a digital agency.
Does the Flat Rate Scheme Work for Ecommerce Brands?
The honest answer: it depends on your cost structure. Let's look at the two sides.
When the FRS can work in your favour
If your business buys meaningful amounts of physical stock each quarter and your goods costs reliably exceed 2% of VAT-inclusive turnover, you'll likely pass the LCT test and qualify for the 7.5% retail rate. In that scenario:
•The admin burden is genuinely lower, no input VAT tracking on most purchases
•VAT forecasting is simpler and more predictable each quarter
•If your input VAT on purchases would be relatively low anyway, the flat rate can leave you a small financial benefit
When the FRS works against you
For many growing ecommerce brands, the maths tips the other way. Consider:
•Import VAT on overseas stock purchases: if you're buying from China or the EU, you're paying meaningful VAT on imports that you'd normally reclaim in full under the standard scheme, but can't under FRS
•Amazon advertising and platform fees: VAT on your Amazon PPC, Amazon seller fees, and Shopify subscriptions adds up quickly but counts for nothing in the LCT test
•Professional services: your accountant, solicitor, and logistics partners all charge VAT , none of it reclaimable under FRS
•Zero-rated exports: if you export to the US or outside the UK, those sales are zero-rated, but the flat rate still applies to your gross turnover including those sales
This last point catches Amazon sellers expanding internationally particularly hard. You collect no VAT on US exports, but if you're on the FRS, you still pay 7.5% of that gross turnover to HMRC.
The more you spend on services, imports, and ad platforms relative to your UK taxable turnover, the more likely the standard VAT scheme is the financially smarter choice.
A Practical Comparison: FRS vs Standard VAT
Let's run the numbers for a hypothetical Shopify + Amazon brand with £120,000 VAT-inclusive quarterly turnover (£100,000 net):
Standard VAT Scheme
•VAT collected from customers: £20,000
•Input VAT on stock (£25k net purchases, UK supplier): £5,000
•Input VAT on imports: £1,500
•Input VAT on Amazon fees, PPC, software, accountancy: £1,200
•Total VAT reclaimed: £7,700
•Net VAT paid to HMRC: £12,300
Flat Rate Scheme (retail 7.5%)
•FRS payment: 7.5% × £120,000 = £9,000
•No input VAT reclaimed on any purchases
•Net VAT paid to HMRC: £9,000
In this example, the FRS appears to save £3,300 per quarter. But now change the scenario , reduce UK stock purchases, increase import VAT and ad spend , and the FRS can easily become the more expensive option. Run your own numbers before you decide.
The New VAT Registration Picture: MTD and What's Changing
If you're approaching the £90,000 VAT registration threshold, it's worth knowing that Making Tax Digital (MTD) for VAT now applies to all VAT-registered businesses. The Flat Rate Scheme is fully compatible with MTD, so that shouldn't be a deciding factor either way.
One other detail worth knowing: if you join the FRS in your first year of VAT registration, HMRC gives you a 1% discount on your flat rate for those initial 12 months. At 7.5%, you'd pay just 6.5% for the first year , a useful small saving while you're finding your feet.
When Should You Leave the Flat Rate Scheme?
There are a few clear signals that the FRS has stopped working in your favour:
•Your import VAT bills are climbing and you can't reclaim any of it
•Your advertising spend on Amazon PPC or Meta ads is significant and growing
•You're exporting a material proportion of your revenue to the US or EU (zero-rated but still caught by the flat rate calculation)
•Your total income approaches £230,000, including VAT, at which point you must leave anyway
•Your goods spend falls below 2% of turnover in most quarters, triggering the 16.5% LCT rate
If any of these apply, it's worth modelling both schemes against your actual figures before your next VAT return.
The Bottom Line for Ecommerce Brands
The Flat Rate Scheme isn't a universal win for ecommerce businesses , and it's certainly not as simple as 'pay less VAT and do less admin'. For a young, small product brand with straightforward UK stock purchases and limited service costs, it can still be useful in those early months.
But as your business grows , more ad spend, more imports, more international sales, more software subscriptions , the standard VAT scheme almost always becomes the more financially sound option. The key is making the decision based on your actual numbers, not the scheme's reputation for simplicity.
