The VAT Law changed the same day e-invoicing arrived

Most of the noise around UAE tax in 2026 has been about e-invoicing. The VAT Law changed too, quietly, on the same day. Federal Decree-Law No. 16 of 2025 amended the original VAT Law (Federal Decree-Law No. 8 of 2017) with effect from 1 January 2026, and four of those changes land directly on a Dubai finance team’s desk: you no longer issue a self-invoice under the reverse-charge mechanism, the FTA can deny your input VAT where a supply is tied to tax evasion, refund and excess-credit claims now sit inside a five-year limit, and the simplified tax invoice is being reshaped for e-invoicing under Cabinet Decision No. 100 of 2025. None of it touches the 5% rate. If you would rather not handle this in house, this is what our VAT consultants in Dubai covers.

None of these changes is a headline-and-move-on item. Each one changes your paperwork, your recovery position, or your deadlines. Two of the four actually cut your workload. The other two raise your risk if you are sloppy. So this is a read-it-once, fix-the-process update, best handled before your next VAT return rather than after an FTA query.

What Federal Decree-Law No. 16 of 2025 actually changes

The Ministry of Finance published the amendment in 2025, effective 1 January 2026. Advisers at KPMG and DLA Piper read it the way we do: the theme is tighter anti-evasion controls paired with a few genuine simplifications. Here are the four that matter, side by side, before we take each one apart.

The self-invoice under reverse charge is gone

Start with the good news. If you buy services or goods that fall under the reverse-charge mechanism — imported software, consultancy from an overseas firm, certain goods — you used to issue a tax invoice to yourself to document the VAT. That self-billing step is gone. You account for the VAT exactly as before, but instead of generating a self-invoice you retain the supporting documents for the transaction. Less busywork, same tax outcome. The catch is hiding in one word: retain.

1. The supplier’s invoice or equivalent document for the imported service or good.
2. The contract or purchase order showing the nature and value of the supply.
3. Import, shipping or customs documentation where goods crossed a border.
4. Your VAT accounting record showing the output and input entries for the reverse charge.

When the FTA can deny your input VAT

This is the change with teeth. The amendment splits into a must and a may. The FTA must deny your input VAT recovery where a supply, or the chain behind it, is connected to tax evasion that you knew or should have known about. That last phrase does the work. Pleading ignorance is not a defence if a reasonable business would have spotted the problem. Separately, the FTA may deny input recovery where a transaction lacks commercial substance or forms part of a tax-avoidance arrangement. Read together, they push the burden onto you to know who you are trading with.

In practice, this rewards basic supplier due diligence. Check the counterparty holds a valid TRN. Keep evidence the supply is real and priced at arm’s length. The businesses most exposed are the ones buying through a long or unfamiliar supply chain and reclaiming large input credits with no paper trail behind the commercial logic. That is now a VAT control, not admin.

The five-year clock on refunds and excess credit

The amendment puts a hard edge on time. VAT refund claims, and carrying forward excess recoverable input tax, now sit inside a five-year limit measured from the end of the tax period in which the amount arose. This lines up with the refund limit already in the tax-procedures framework. If you are sitting on an old VAT credit waiting for a rainy day, that day now has a deadline. The action is simple: age your recoverable-VAT balance and claim or use anything approaching the five-year mark before it lapses.

The simplified tax invoice is being reshaped

The fourth change ties VAT into the e-invoicing rollout. The content rules for the simplified tax invoice (the short receipt many retailers issue) are being aligned with the e-invoicing Executive Regulation, Cabinet Decision No. 100 of 2025. As structured e-invoicing phases in, the simplified format stops being a standalone option for in-scope supplies. Run a point-of-sale-heavy operation such as retail, F&B or a clinic? Check what your till actually prints now, and whether your provider is on the roadmap. We cover the full mandate in our UAE e-invoicing guide.

A worked example: a Business Bay IT firm on the reverse charge

Take a Business Bay IT services company that imports cloud software licences from an overseas vendor, AED 2,400,000 over the year. Under reverse charge it accounts for output VAT of AED 120,000 (5%) and reclaims the same AED 120,000 as input VAT, netting to nil. From 1 January 2026 it stops issuing itself a self-invoice for each import and instead files the vendor invoices, the licensing contract and its VAT workings. Now the sting. Suppose part of that supply chain turns out to be connected to evasion the firm should have questioned: an implausible price, a vendor with no real substance. The FTA must deny the AED 120,000 input recovery. The output VAT still stands. A transaction that netted to zero becomes a real AED 120,000 VAT cost, plus penalties. That is why the due-diligence file is not optional.

Where this leaves you

None of this touches the 5% rate, and none of it is optional. Two of the four changes cut your workload; two raise your risk if you cut corners. The move this quarter is a short process review: stop self-billing under the reverse charge and file the documents instead, tighten supplier due diligence so input recovery holds up, and age your VAT credits against the five-year clock. Our guide to the reverse-charge mechanism walks through the mechanics, and our accounting team in Dubai can run the review and rebuild the paperwork trail so an FTA query is a non-event.
