UAE VAT Return Filing: The VAT 201 Form Box by Box, Deadlines and the Mistakes That Cost You

When is your VAT return due?

Your VAT return must reach the Federal Tax Authority (FTA) by the 28th day after your tax period ends, and payment is due by the same date. If that day is a weekend or a national holiday, the deadline moves to the next business day. For a quarter ending 30 September 2026, that means Wednesday 28 October 2026.

The VAT 201 form box by box: one quarter, filled in

The company below is fictional: a Dubai mainland trading LLC with one establishment, in Dubai, filing quarterly. Every figure is illustrative, and each VAT figure on a standard-rated line is 5% of its amount. This is its July to September 2026 return.

The AED 8,000 invoice stays out of Box 9 because it lacks the supplier's TRN. For a purchase from a UAE supplier, you can deduct input VAT only once you hold a valid tax invoice, or a document the law accepts in its place (Article 55 of the VAT Decree-Law), and Article 59 of the VAT Executive Regulation requires the supplier's TRN both on a full tax invoice and on the simplified tax invoice allowed for supplies of AED 10,000 or less. Ask the supplier for a valid tax invoice before you claim anything on it.

Explain every row of that table and you've also rehearsed the VAT round of a Dubai accountant interview.

Five VAT return filing mistakes in the UAE, and what each costs in AED

Each case uses the example company above.

1. From 1 October 2026: claiming input VAT without supplier checks

FTA Decision No. 13 of 2026 requires you to check, and document, both the supplier and the supply before you deduct input VAT. For an individual supplier that means ID plus an in-person or virtual meeting; for a company, an incorporation check plus the authorised person's ID.

You also confirm a real place of business, watch for risk signs such as an address or key staff changing more than twice in 12 months, and get a bank's written confirmation of the supplier's account once purchases from that supplier pass, or are expected to pass, AED 375,000 over 12 months.

For the supply, record the commercial reason and pay electronically; any cash must be documented, within the limits and verifiable. Check that the price or margin matches the market and the supply sits within the supplier's licence, and know where the goods came from and why any intermediary is involved.

Re-verify each supplier every 12 months and keep a written policy naming who is responsible. Purchases under AED 10,000 before VAT fall outside the checks, unless purchases from that supplier pass, or are expected to pass, AED 100,000 over 12 months.

Cabinet Decision No. 149 of 2026 adds a second rule from the same date. Its new Article 54(3) blocks input VAT on a supply above a set amount when it is paid, or meant to be paid, in cash. The Minister of Finance will set that amount by Ministerial Decision; as of 21 September 2026, we found none published.

What it costs: the input VAT itself. Since 1 January 2026 the FTA can refuse input VAT on a supply it finds was part of a tax-evasion arrangement, and skipping these checks makes that refusal easier to justify. An AED 60,000 purchase from a supplier you never checked carries AED 3,000 of VAT you may not be able to put in Box 9.

For the example company, the first return with October purchases in it covers October to December 2026, due 28 January 2027. The texts we read don't say how a purchase straddling 1 October is treated, so ask before you claim one.

2. Claiming input VAT on an invoice that isn't a tax invoice

Now suppose the example company claimed AED 12,000 of input VAT on invoices without the supplier's TRN in its April to June return, due 28 July 2026.

It finds the problem on 1 September and files a Voluntary Disclosure on 15 September, inside the 20 business days. The Voluntary Disclosure penalty covers two periods, 29 July to 28 August and part of the next month: 2% of AED 12,000, or AED 240, plus the AED 12,000 itself. The AED 500 incorrect-return penalty may be added on top.

Had the FTA notified an audit first, the fixed 15% alone would be AED 1,800. The registration, record-keeping and per-invoice penalties that catch UAE startups are covered separately.

3. Zero-rating a sale into a Designated Zone

A mainland company selling goods into a Designated Zone makes a local supply at 5%, not an export. That's why the example's AED 50,000 sale sits in Box 1b, not Box 4.

Put that sale in Box 4 and output VAT is AED 2,500 short. That is under AED 10,000, so you correct it in a later return.

At AED 300,000 of Designated Zone sales, the shortfall would be AED 15,000: a Voluntary Disclosure within 20 business days, plus the 1% monthly penalty. How mainland and Designated Zone companies are taxed covers the setup side.

4. Missing the reverse charge

Leave the overseas advertising out of Boxes 3 and 10, and a fully taxable business like the example pays the same: AED 900 out, AED 900 back. But the return is wrong in two boxes, and if you also make exempt supplies, you can recover only part of that VAT in Box 10, so the part you can't recover is tax you owe.

Since 1 January 2026 you no longer issue yourself an invoice under the reverse charge (Federal Decree-Law No. 16 of 2025), but you must keep the supporting documents. The texts we read don't say how the penalty rules treat an error with no net effect, so correct it rather than assume it's free.

5. Filing or paying late

A late VAT return costs AED 1,000 the first time and AED 2,000 for a repeat within 24 months. Late payment runs at 14% a year, charged for each month or part of a month from the day after the due date.

Say the example company pays its AED 12,100 on 5 December instead of 28 October. That's one full month plus part of a second, so two periods: 12,100 × 14% ÷ 12 is about AED 141.17 a period, so about AED 282 for the two. File the return late as well, and add AED 1,000.
