You have 30 days to register. The date is already running

The 30 days start from the day you became liable

The form is the easy part. Dating the liability is not.

Under Article 13 of Federal Decree-Law No. 8 of 2017, a person with a place of residence in the UAE must register once the supplies listed in Article 19 have already exceeded the mandatory threshold over the previous 12 months, or once those supplies are expected to exceed it in the next 30 days. Cabinet Decision No. 52 of 2017 Article 7 then gives you 30 days from the day you became required to register to file the application.

The 30 days do not start when your accountant flags it. They do not start when the trade licence is renewed. They do not start when you first log into EmaraTax.

If the Authority has to register you itself, it does so from the date you first became liable, and it imposes the penalty.

That is Article 7(3).

The historic test and the forward test set different start dates

Most finance teams run the historic test at month-end. Add taxable supplies and concerned imports for the last 12 months. If the figure is already above AED 375,000, waiting another month to see how trading goes is how the application becomes late.

The forward test is quieter. In our experience it is the one that actually catches a growing business. Sign a contract that will take you through the threshold inside 30 days and the obligation exists on the day you have reasonable grounds to expect it. You do not get to wait for the cash.

Registration does not start on the same day under both tests.

On the historic test, Article 7(4) registers you from the first day of the month after the month you became required to register, or from an earlier date you agree with the Authority. Cross the line in March and the number runs from 1 April, applied or not.

Article 7(5) treats the forward test differently. Registration starts on the date those reasonable grounds existed, which can be the contract date itself.

A non-resident who makes a taxable supply in the UAE, with nobody else accounting for the tax, is required to register regardless of value. Article 13(2) has no threshold. Article 7(6) starts that registration on the day the supplies began.

Capital assets stay out of the threshold. Article 20 takes them out. Selling the warehouse does not, by itself, push you over AED 375,000.

What EmaraTax asks for, in the order it asks

Registration is free.

The FTA VAT Registration service card, last updated 13 July 2026, puts a ready application at about 45 minutes to submit, and 20 business days for the Authority to finish a complete one.

Start with the account.

Create or open EmaraTax. Build the taxable person profile. Open that account.

Hit Register under Value Added Tax. Then the form.

Documents sit behind that click, and they change with the legal form. For a company the service card names these:

• Certificate of incorporation, memorandum of association, or partnership agreement
• Commercial registration, or the equivalent paper from the licensing authority
• A valid trade licence, plus every branch licence
• Emirates ID and passport copies for owners and authorised signatories
• A power of attorney if the signatory is not named as manager on the memorandum
• An official turnover declaration, stamped and signed, covering taxable supplies from establishment to the application date
• Supporting invoices, purchase orders, contracts, title deeds, completion certificates or leases, as the type of application requires
• For an expenses-based voluntary application, at least five VAT invoices whose amounts exceed the registration threshold
• For expected revenue, purchase orders or contracts stamped and signed by both parties
• A bank letter, optional, in the company's name
• Customs details if you import

PDF only. Fifteen megabytes per file.

Sole establishments owned by the same natural person share one TRN. The threshold is the combined figure. Branches of a company do the same: one TRN, one return, every branch listed.

A person carrying on an economic activity in the UAE can be required to register even without a trade licence. The service card says so in its terms. Waiting for the licence to be issued is not a defence.

The files that send the application back

The FTA's 20 business days run from a completed application.

An incomplete one sits.

In our experience the stall is almost never a missing passport scan. It is a number that does not add up.

The turnover letter says AED 420,000. The invoices attached add to AED 310,000.

Or they add to AED 610,000 and nobody has explained the gap. The reviewer sends it back. The taxpayer's 30-day clock, which started on the liability date, does not pause while that correspondence runs.

A trade licence that expired last month will also bounce it. So will a signatory who is not on the memorandum and has no power of attorney, a bank letter in a shareholder's personal name, and an expected-revenue application supported only by a draft quotation. Designated-zone traders who cannot produce a goods-flow note get the same result. The service card calls that last one out.

Related companies that look as if they were split to stay under the threshold get a different treatment again. Article 13 of the Executive Regulation lets the Authority aggregate their taxable supplies. Each person is then treated as making the others' supplies, and each must apply if the combined figure has crossed AED 375,000.

What a late application actually costs

The late-registration penalty is AED 10,000. Table 1, item 3 of Cabinet Decision No. 40 of 2017, as amended by Cabinet Decision No. 129 of 2025, charges that amount for failing to file inside the window. It is a flat figure. It does not grow with the delay.

What grows is everything sitting underneath it.

Article 7(7) makes a late registrant account for and pay the tax on every taxable supply and import made before the TRN was issued. If you did not charge customers 5 percent, you pay it yourself. The first return still has a 28-day deadline under Article 64 of the Executive Regulation. Unpaid tax from 14 April 2026 is 14 percent a year, charged monthly or for part of a month.

A worked example, using figures we see often enough.

A trading LLC issued an invoice of AED 82,000 on 18 March 2026. That invoice took its rolling 12-month taxable supplies from AED 308,000 to AED 390,000. It became required to register on 18 March.

The application was due on 17 April. The historic-test effective date is 1 April. The company applied on 12 July.

From 1 April to 30 June it invoiced AED 150,000, then AED 160,000, then AED 170,000. None of it carried VAT. If the Authority assigns the April-to-June stagger, the first quarterly return is due on 28 July, while the TRN is still in process.

None of that required a dispute about the law. It was a calendar, and a decision to wait for a tidier file.

Voluntary registration is a different evidence pack

Article 17 of the VAT Law lets you apply if you are not yet required to. The figure is AED 187,500 of taxable supplies or of taxable expenses, already incurred over 12 months or expected in the next 30 days.

Taxable expenses, for this purpose, means standard-rated expenses incurred in the UAE by a resident. Article 8(5) of the Executive Regulation is that specific. Overseas costs and zero-rated costs do not get you in.

The Authority registers a voluntary applicant from the first day of the month after the application, or from an earlier date you request and it accepts. Article 8(3) also wants evidence of an intention to make taxable supplies or incur taxable expenses above the line, if you are applying on the forward test.

A person who registered voluntarily cannot apply to deregister inside 12 months of the registration date.

Article 23 is blunt about it. If the only reason you are applying is to look established to a landlord or a bank, read the deregistration clock first.

The first return is where the pre-registration VAT sits

Once the certificate is on the dashboard, you charge 5 percent and you keep the records. The standard tax period is three calendar months, ending on a date the Authority sets, under Article 62. You do not pick it. The first VAT201 is due on the 28th day after that period ends.

Article 56 of the VAT Law lets you recover input tax incurred before registration, on that first return, for goods and services used to make supplies that themselves give a recovery right. Goods and services taken for other purposes are out. So is the depreciated part of a capital asset, any service received more than five years before the registration date, and goods moved to another implementing state before you registered here.

That first return is also the last easy chance to pick those amounts up. Miss them and you are into the ordinary recovery rules, and since 1 January 2026 unused credit is on a five-year clock under the amended Article 74.

The most common mistake we see is not a missing document.

It is waiting.

The licence is being renewed. The invoices are being tidied. The 30 days run from the liability date regardless.

By the time the tidy file is uploaded, the application is late, the effective date has already passed, and the turnover letter still does not match the invoices, so the Authority's 20 business days have not started either.

One thing remains unsettled.

Article 17 dates the voluntary historic test at the end of any given month. Article 13, the mandatory test, does not use that phrase. Article 7(4) then keys the effective date to the month in which the Person is required to register.

We have not seen a published FTA decision that pins a mid-month invoice, the one that actually crossed AED 375,000, as the trigger date rather than the month-end. Date it on the invoice if you want the conservative answer. Do not assume the Authority will give you until the 31st.

A short checklist

If you think you might already be liable, this afternoon is enough.

1. Build the rolling 12-month taxable supplies figure, month by month, including concerned imports. Find the first month it went through AED 375,000. That is your candidate historic trigger.
2. Look at signed contracts and confirmed orders for the next 30 days. If those alone take you through the line, the forward test has already started.
3. Count 30 calendar days from the earlier of those two dates. If that date has passed, the priority is to file, not to perfect the pack.
4. Write the turnover letter from the invoices you will attach, not from the management account. Then attach those invoices.
5. Check the memorandum against the signatory. If the names do not match, get the power of attorney before you upload.
6. List input tax on goods still held and on services received in the last five years. That schedule belongs in the first return.

Then apply. Then put the first 28th in the diary.
