Accounting and VAT compliance for Abu Dhabi businesses

Abu Dhabi's economy is weighted toward energy services, government and semi-government contracting, construction, healthcare and education, plus the financial-services cluster in ADGM. That mix shapes the accounting: long project cycles, milestone billing, retention amounts held back for months, and buyers — ADNOC group companies, Aldar, government departments — who enforce strict invoice formats and purchase-order matching before payment.

For VAT, retention and advance payments are where Abu Dhabi contractors most often get the timing wrong. The tax point follows the earlier of the invoice date, payment received or the date of supply, so an advance received in one quarter must be declared in that quarter even if the work runs into the next. DocMakBooks handles milestone and retention billing as separate documents with their own tax points, and maps everything into the VAT 201 boxes for the 28th-of-the-month FTA deadline.

ADGM entities have an extra consideration: financial statements are prepared under IFRS and, depending on the licence, may require audit. Keeping projects, cost centres and intercompany balances separated from day one makes both the corporate tax return and the audit dramatically cheaper than a year-end clean-up.
