What Is the VAT Registration Threshold?

Rolling twelve months: how a December-year-end business crosses in July

The business crosses in July. Its financial year does not end until December. A business reviewing the threshold at its year end discovers a five-month-old obligation, with retroactive VAT on every supply since July.

Figures are illustrative. The point is the timing, not the amounts.

Why that is the answer

There are two separate tests and a business is caught by whichever bites first.

The backward-looking test. Taxable supplies and imports over the previous twelve months, measured continuously. Not the calendar year, not the financial year, not the VAT period. At any point in any month, the question is what the preceding twelve months total.

The forward-looking test. Whether you expect taxable supplies to exceed the threshold within the next thirty days. This is triggered by reasonable expectation rather than by an invoice, so a signed contract that guarantees the threshold triggers it on signature.

The second is the one that surprises businesses most. A company that wins a large contract in March, invoices in June and gets paid in August has an obligation dating from March, not August, and not the year end.

Both tests use the same measure: taxable supplies and imports. Not revenue, not profit, not receipts.

What counts towards the threshold

The measure is narrower than total revenue in some ways and broader in others:

• Standard-rated supplies: count
• Zero-rated supplies: count. They are taxable supplies at a 0 per cent rate, not supplies outside the system
• Imports of goods and services: count, including services subject to reverse charge
• Exempt supplies: do not count
• Out-of-scope supplies: do not count
• Sale of capital assets: generally excluded from the calculation
• Measured on supplies made, not cash received. A business invoicing on 60-day terms crosses on the invoice, not the payment

The zero-rated point catches exporters repeatedly. A business selling entirely abroad charges no VAT and reasonably concludes it is outside the system, but its supplies are taxable, it must register, and once registered it is generally in a recoverable input tax position, which is usually to its advantage anyway.

The voluntary threshold works differently

The voluntary threshold is AED 187,500 of taxable supplies, imports or taxable expenses, and note the inclusion of expenses, which the mandatory test does not have.

That difference is deliberate and it matters. It means a business with very little revenue but substantial taxable spending can register voluntarily. A start-up fitting out premises, buying equipment or paying for development has taxable expenses well above the voluntary threshold long before it has meaningful sales.

For that business, voluntary registration allows recovery of input tax on the capital phase, frequently a substantial sum, and generally the single strongest case for registering early.

The practical caution is that registration is not costless. Quarterly returns, record-keeping and eventually e-invoicing implications all follow. It is worth doing when the recoverable input tax is material, and not worth doing for a small business making consumer sales with modest costs.

Monitoring it properly

Because the test is rolling, checking it annually is structurally inadequate. It can be crossed in any month and the obligation begins then.

What works is a rolling twelve-month total of taxable supplies, calculated monthly and looked at by somebody. In most accounting systems this is a saved report rather than a project, and it takes minutes once configured.

What to watch for: the total approaching AED 375,000 of taxable supplies and imports over the previous 12 months, or expected within the next 30 days, the monthly figure rising, and any signed contract that would take you over within thirty days. That last one does not appear in any report, so it needs to be a question asked when significant contracts are signed rather than a number monitored.

Businesses that do this never register late. Businesses that check at the year end frequently do, and by then the exposure has been accruing for months.

Where the measurement most often goes wrong

Four patterns account for nearly every late registration we are asked to fix, and none of them involve anyone being careless:

• The netting error. A business recording revenue after deducting commission, platform fees or subcontractor costs is measuring a figure below its actual taxable supplies. E-commerce sellers and agencies are most affected, and the gap can be substantial
• The multi-entity error. Supplies are measured per taxable person. Businesses running two licences sometimes measure them together and conclude neither has crossed, or measure separately and miss that one has
• The exempt-inclusion error. Including exempt income inflates the figure and prompts a registration that was not required, less costly than the reverse, but it creates an obligation and a compliance burden out of nothing
• The start-date error. A business that has been trading for eight months measures only those eight months, which is correct, but then keeps using an eight-month window rather than rolling forward to a full twelve

The first is the one worth checking today if you sell through any intermediary. Gross taxable supplies is the measure, and the number your bank account sees is not it.

The common misunderstanding

• Measuring against the financial year when the test is rolling and continuous.
• Ignoring the forward-looking limb, which is triggered by expectation rather than invoicing.
• Excluding zero-rated supplies, which are taxable supplies and do count.
• Including exempt supplies, which do not.
• Measuring cash received rather than supplies made.
• Forgetting that expenses count towards the voluntary threshold, which is what makes it available to start-ups.
• Checking annually when the threshold can be crossed in any month.

What to do next

1. Build a rolling twelve-month total of taxable supplies as a saved monthly report.
2. Split taxable from exempt in that report, since only the first counts.
3. Ask the thirty-day question whenever a significant contract is signed.
4. If you are a start-up with heavy spend, check the voluntary threshold on expenses.
5. If the total is near AED 375,000 of taxable supplies and imports over the previous 12 months, or expected within the next 30 days, plan the registration rather than waiting to cross.
