When is VAT due on retention in the UAE?
Honestly: the treatment of retention specifically is interpretively contested, and anyone giving you a confident one-line answer is overselling their certainty. What is not contested is the broader timing — VAT on continuous construction supplies falls due at certification, invoice or payment, whichever is earliest. Which on a 90-day cycle means remitting tax on money you have not received. This is not tax advice. Take some.
The part that is clear
For continuous supplies, the tax point is triggered by the earliest of certification, the issue of a tax invoice, or receipt of payment. In construction, certification usually comes first — often by a wide margin.
So the contractor certifies in January, remits the VAT for that period, and receives the cash in April. The tax has been paid out of working capital for three months. That is not an edge case; on a 90-day payment cycle it is the normal case, and it is a genuine drain that most invoice systems do not model at all.
The part that is not clear
Retention is money certified but deliberately withheld, sometimes for years, and released against triggers that may never cleanly occur. Applying a timing rule designed for ordinary supplies to that is genuinely awkward, and practitioners do not all read it the same way.
We are not going to resolve that for you in a paragraph on a vendor’s website, and we would be suspicious of anyone who tried. The tension is real, the stakes are real, and the answer depends on facts we cannot see.
What to actually do
Confirm your treatment with a tax adviser, in writing, for your contracts. Then model it — certified against paid against VAT-due — so the working-capital position is visible in advance rather than experienced in arrears.
A system that does not show you the gap between what you have certified, what you have been paid, and what you owe the tax authority is not being neutral about that gap. It is hiding it.
