It's one of the most common timing questions we get — and an easy one to get wrong. A business has issued invoices but is sitting on unpaid receivables because of credit terms. The owner assumes that until the cash actually lands, those sales don't "count" for VAT. So they wait.
That assumption costs people. UAE VAT doesn't work on a cash basis. Your turnover for VAT purposes is built from the supplies you make — generally when you invoice or deliver — not from the day a customer pays you.
✅ The short answer
Yes — with AED 200,000 of taxable invoices already issued, you're above the AED 187,500 voluntary registration threshold and can register today. Whether the client has paid is irrelevant to your eligibility. You count the supply when it happens, not when the money arrives.
The two thresholds
When can — and must — you register?
UAE VAT has two registration lines, both measured on the value of your taxable supplies and imports (and, for voluntary registration, taxable expenses too):
| Threshold | Amount | What it means |
|---|---|---|
| Mandatory | AED 375,000 | You must register once taxable supplies + imports exceed this over the past 12 months, or you expect to exceed it within the next 30 days. |
| Voluntary | AED 187,500 | You may register once taxable supplies, imports, or taxable expenses exceed this — useful for recovering input VAT and signalling credibility. |
At AED 200,000 of invoiced sales, the business in our example sits comfortably above the voluntary line but below the mandatory one — squarely in "you can choose to register" territory.
The key principle
Turnover is measured on supplies made — not cash received
This is the heart of it. The threshold test looks at the value of taxable supplies you have made, evidenced by your invoices and your accounting records — not by your bank statements. One of the most common VAT errors is calculating turnover from bank deposits instead of invoices, which understates your position and leads businesses to register late.
So AED 200,000 of invoices raised this period is AED 200,000 of taxable supplies — full stop. The 30-day wait for payment changes nothing about your VAT standing.
The rule to remember
"Whichever is earlier": the date of supply
UAE VAT pins each sale to a date of supply (the "tax point") under Article 25 of the VAT Law (Federal Decree-Law No. 8 of 2017). The date of supply is the earliest of the following events:
| Trigger event | Date that applies |
|---|---|
| Goods delivered / made available, or service completed | Date of delivery or completion |
| A tax invoice is issued | Date of the invoice |
| Payment is received | Date of payment |
Whichever of these happens first is the date the supply is recognised for VAT. For most trading and service businesses on credit terms, that's the moment you deliver or invoice — well before the customer pays. Payment is simply the last of the three to occur, so it rarely drives the date.
The phrase to keep in your head: VAT follows the earlier of invoicing, delivery, or payment — never just "when we got paid."
Don't get caught here
The cash-flow catch every credit business should know
Here's the flip side, and it's important once you're registered. Because output VAT is triggered by the date of supply — not by payment — you can be required to account for and pay VAT to the FTA before your customer has paid you. Invoice on 30-day terms near the end of a tax period, and the VAT on that sale can fall due in your return while the receivable is still outstanding.
⚠️ Plan for the timing gap
The UAE doesn't operate a general cash-accounting scheme, so build the VAT-versus-collection gap into your cash flow. Tightening payment terms, invoicing timing, and provisioning for VAT on unpaid invoices all help you avoid a return that's due before the cash is in.
Worth it?
Should you register voluntarily?
Being eligible isn't the same as it being the right move. Voluntary registration tends to make sense when:
- Your customers are VAT-registered businesses They can recover the VAT you charge, so adding 5% doesn't make you less competitive — and a TRN signals you're an established operator.
- You're incurring input VAT Registration lets you recover VAT on your own costs (setup, rent, services), improving margins.
- You're about to cross AED 375,000 anyway Registering ahead of the mandatory line avoids a last-minute scramble and the AED 10,000 late-registration penalty.
It's less attractive if most of your customers are consumers or non-registered businesses, since the 5% becomes a real cost to them — and you take on quarterly filing obligations either way.

The takeaway
Don't wait for the money
If you've issued AED 200,000 of taxable invoices, you've made AED 200,000 of taxable supplies — and you can register for VAT now, paid or not. The same principle that makes you eligible early also means VAT will fall due on the date of supply once you're registered, so treat registration as a moment to get your invoicing, records, and cash-flow planning in order at the same time.

FAQ
Frequently asked questions
Can I register for VAT if my client hasn't paid yet?
Yes. VAT registration eligibility is based on the value of taxable supplies you've made — evidenced by your invoices — not on cash received. If your invoiced supplies exceed AED 187,500 you can register voluntarily; above AED 375,000 it becomes mandatory.
Does turnover for the VAT threshold mean money in the bank?
No. It means the value of taxable supplies and imports you've made over a rolling 12 months (or expect in the next 30 days). Calculating from bank deposits instead of invoices is a common mistake that causes businesses to register late.
What is the "date of supply" and why does it matter?
It's the tax point — the date a sale is recognised for VAT. Under Article 25 of the UAE VAT Law it's the earliest of: delivery/completion, the tax invoice date, or the date of payment. It determines which return the VAT belongs in.
Will I have to pay VAT to the FTA before my customer pays me?
Potentially, yes. Because output VAT is due based on the date of supply rather than payment, VAT on a credit-term invoice can fall due in your return before the receivable is collected. Plan your cash flow around this gap.
Is voluntary registration worth it for a small business?
It depends. It's beneficial if your customers are VAT-registered (they recover the VAT you charge) and you incur input VAT you'd like to recover. It's less attractive if you mainly sell to consumers, since the 5% becomes their cost. We can assess your specific case.
