The UAE's VAT system, now eight years old, moved on five distinct fronts in 2026: a major e-invoicing mandate built on a genuinely different technical model than its Gulf neighbors, a set of VAT law amendments that tighten refund timelines and shift evidentiary burden onto buyers, a quietly retroactive correction to how tolls and parking are taxed, an expanded refund scheme for citizens building homes, and a narrower anti-fraud measure on scrap metal.
E-invoicing, but not Saudi's model
The UAE's e-invoicing mandate, formalized under Ministerial Decisions No. 243 and 244 of 2025, takes a different technical approach than Saudi Arabia's. Where ZATCA operates a clearance model — invoices submitted to the tax authority for approval before reaching the buyer — the UAE has adopted a decentralized Peppol-based "5-corner" model (DCTCE): an invoice moves from supplier to the supplier's Accredited Service Provider (ASP), to the buyer's ASP, to the buyer, while the supplier's ASP reports tax data to the Federal Tax Authority in parallel. The FTA receives transaction data without sitting in the middle of every exchange. B2C transactions are excluded at this stage — a contrast with Oman, which is building its own Peppol-based system to cover B2B, B2G, and B2C from the outset.
The rollout is staged by business size. A voluntary pilot opens 1 July 2026. Large businesses, with annual revenue of AED 50 million or more, must appoint an ASP — originally by 31 July 2026, extended on 10 May 2026 to 30 October 2026 — ahead of mandatory go-live on 1 January 2027. Smaller businesses follow from 1 July 2027, government entities from 1 October 2027. Non-compliance penalties, set out in Cabinet Decision No. 106 of 2025, run up to AED 5,000 per month; businesses that adopt the system voluntarily before their mandatory deadline face none during the pilot period. The Ministry of Finance has continued refining the technical guidance through the year — Guidelines Version 1.0 in February, Version 1.1 in June, the latter clarifying storage requirements, ASP duties, and treatment of advance payments.
VAT law amendments: tighter timelines, shifted burden
Separately, Federal Decree-Laws No. 16 and 17 of 2025 amended the VAT Law and Tax Procedures Law, effective 1 January 2026. Three changes stand out. Self-invoicing for reverse-charge imports is abolished — businesses no longer generate an internal tax invoice for these transactions, relying instead on supplier invoices and import documentation as evidence. A statutory five-year limitation now applies to excess input VAT refund claims, counted from the end of the relevant tax period; once it lapses, the right to reclaim or offset the credit disappears permanently. Since this is the first time such a limit has existed, the amendments include one-time transitional relief: businesses whose five-year window had already closed, or would close within a year of the new rule, get until 31 December 2026 to file. Credits from 2021 are the ones actually at risk this year.
The third change is the more structural one: the FTA can now explicitly deny input VAT recovery wherever a transaction is connected to a tax-evasion arrangement and the recipient "knew or should have known" — a standard that extends beyond direct knowledge to constructive knowledge based on what a reasonable business should have checked. Previously, a business could generally rely on VAT being charged and paid; now, accepting an invoice at face value isn't necessarily sufficient if the surrounding circumstances pointed to a problem. The standalone statute-of-limitations provision that used to govern tax audits and assessments has also been formally repealed as part of the same package.
A correction, not a new tax: Salik and Parkin
From 1 June 2026, Dubai's Salik toll system and Parkin parking service began applying 5% VAT to their charges — peak tolls rising from Dh6 to Dh6.30, off-peak from Dh4 to Dh4.20, tag activation fees from Dh100 to Dh105. The notable part isn't the 5% itself; it's how the change arrived. Salik's own disclosure indicates these charges were, in its assessment, always within scope of VAT under the law as it has existed since 2018 — the prior practice of not charging it appears to have been a treatment position rather than a change in the underlying law. Salik applied VAT retrospectively to toll revenue going back to July 2022, totaling roughly Dh471 million including penalties. Motorists won't be charged that retrospective amount; Dubai's Roads and Transport Authority is covering it under a pre-existing arrangement with Salik. Going forward from June, the VAT is simply part of the published charge.
VAT refunds for citizens building homes — wider scope, larger numbers
From 1 January 2026, the FTA expanded the list of construction expenses eligible for VAT refunds available to UAE nationals building new homes. Newly eligible categories include staff accommodation for domestic workers, home gyms, integrated smart-home and security systems, swimming pools, landscaping, and full reconstruction costs including demolition. The FTA projects the expansion will generate roughly AED 200 million in additional savings, at an average of about AED 25,000 per claim, with total approved claims for 2026 expected to exceed AED 1 billion — up from AED 754 million in 2025.
Smaller items, and a regional pattern
A reverse-charge mechanism for scrap-metal trading between VAT-registered businesses took effect 14 January 2026 under Cabinet Decision No. 153 of 2025, shifting VAT accounting from seller to buyer to address fraud risk in a sector where material often passes through several intermediaries — bringing scrap metal in line with the UAE's existing reverse-charge treatment of electronics and precious metals. Separately, the UAE introduced a sugar-based excise tax on sweetened beverages from 1 January 2026, replacing a flat rate with one tied to actual sugar content — the same change Saudi Arabia made on the same date, both following a coordinated GCC committee decision; Qatar adopted its own version of the same model later, effective July 2026.
What it adds up to
Three of these five threads point the same direction: closing gaps between what the law has technically required and what was actually being collected or enforced. The Salik correction is the clearest case — a tax that was arguably always due, simply not charged for years, now corrected without retroactively burdening the people who didn't pay it. The VAT law amendments work similarly in spirit on enforcement: a five-year refund limit closes an open-ended carry-forward that had let credit balances accumulate indefinitely, and the new evidentiary standard closes the gap between a business accepting an invoice and a business actually being entitled to rely on it. The e-invoicing mandate is infrastructure for the same underlying goal, built differently than its neighbors' versions but aimed at the same outcome: real-time visibility into transactions that used to be reconstructed after the fact. Against that backdrop, the home-refund expansion and the scrap-metal reverse charge read as narrower, complementary moves — one extending a citizen benefit, the other patching a known fraud vector — rather than part of the same enforcement push.
