Bookkeeping for DMCC-registered trading companies in the UAE has one obligation most free zones do not: DMCC requires every member company to upload audited financial statements to the Member Portal within six months of the financial year ending — on top of the Federal Tax Authority (FTA) rules on corporate tax registration, VAT and 7-year record retention that apply across the UAE as of October 2026.
TL;DR
- DMCC companies must submit audited financial statements within 6 months of the financial year end.
- Re-invoicing margins must be booked as revenue — the spread you charge, not the invoice total.
- VAT registration is mandatory above AED 375,000 of taxable supplies in 12 months.
- Register for corporate tax on time: the late-registration penalty is AED 10,000.
- Keep records at least 7 years after each tax period ends.
What DMCC adds on top of federal rules
DMCC is a free zone, but its bookkeeping calendar runs on two clocks. Federal rules — corporate tax, VAT, record retention — come from the FTA and apply to DMCC companies like any other UAE business. The free-zone layer adds the annual audit submission, which DMCC enforces through its Member Portal (DMCC, Guidelines – Submission of Audited Financial Statements, 29 April 2025).
- Your auditor must be from DMCC's approved auditors list.
- The auditor signs and stamps the Audited Financial Statements Summary Sheet on their letterhead.
- Both documents upload through a designated service request on the Member Portal within six months of the financial year end.
Missing the window puts the company's compliance record and licence renewals at risk — the audit deadline is a licence issue, not a tax one, and it lands before the corporate tax return for a December year end.
Step 1: Book re-invoicing margins correctly
The classic DMCC trading model is a re-invoice: the Dubai company buys from a supplier and sells to a customer, with goods moving directly between them. The revenue to book is your margin, not the gross invoice value — you are the principal in a sale of goods, so gross sales and cost of sales both hit the ledger, but the profit that drives tax is the spread.
- Book the purchase and the sale at gross values with cost of sales matching — never book only the margin as revenue in the sales ledger.
- Keep every supplier and customer contract: transfer-pricing questions start with the arm's-length character of your margin.
- For related-party re-invoicing, document how the margin was set. The corporate tax law's transfer-pricing rules apply to free zone companies too.
Step 2: Track VAT on imports, exports and re-exports
Trading companies hit VAT from several directions at once, and each direction has its own treatment:
- Goods imported into the UAE attract import VAT, recoverable as input tax where the supply chain supports it.
- Goods exported outside the UAE can qualify for the 0% rate with evidence of export; keep shipping documents with each invoice.
- Domestic UAE sales are standard-rated at 5%.
- Reverse charge applies on certain imports, so the return must show both output and input sides.
Registration itself is threshold-driven: mandatory above AED 375,000 of taxable supplies and imports over the previous 12 months, voluntary above AED 187,500 (FTA, Registration for VAT). A trading company's rolling 12-month test moves fast — check it monthly, not at year end. The registration process is covered step by step in VAT registration in the UAE: thresholds and deadlines.
Step 3: Meet the federal corporate tax calendar
Corporate tax registration and filing apply to DMCC companies regardless of free-zone status. The administrative penalty for late registration is AED 10,000 (FTA, Corporate Tax Registration); companies incorporated on or after 1 March 2024 had 3 months from incorporation to register, with staggered licence-month deadlines for earlier entities (FTA, Public Clarification on registration timelines). The FTA's waiver initiative can exempt the penalty where the first tax return or annual declaration is submitted within 7 months of the end of the first tax period (FTA, Waiver of Penalties).
Whether trading income qualifies for the free zone's 0% rate on qualifying income depends on DMCC's status as a designated zone and the qualifying activities rules — income that does not qualify falls to the standard 9% rate. That qualification is evidenced from the books, which is why the margin, the customer location and the goods flow must all be traceable ledger-to-contract.
| Obligation | Rule (as of October 2026) | Source |
|---|---|---|
| DMCC audit submission | Audited financial statements + summary sheet via Member Portal within 6 months of FY end | DMCC guidelines |
| Corporate tax registration | Deadline tied to incorporation/licence date; AED 10,000 late penalty | FTA services page |
| VAT registration | Mandatory above AED 375,000 taxable supplies/imports in 12 months; voluntary above AED 187,500 | FTA, Registration for VAT |
| Record retention | At least 7 years after the tax period ends | FTA, 28 Aug 2025 |
Step 4: Retain records for seven years
The FTA requires taxable persons and exempt persons to keep records for at least seven years following the end of the tax period they relate to (FTA, 28 August 2025). For a DMCC trading company that archive should include:
- Supplier and customer contracts, including related-party agreements and margin documentation.
- Shipping documents, customs declarations and proof of export for 0% VAT supplies.
- Bank statements and reconciliations for every currency account.
- The audited financial statements and DMCC summary sheet for each year.
Common mistakes DMCC trading companies make
- Treating the audit as a tax deadline. The DMCC submission is due at 6 months, before the corporate tax return at 9 months — a December year end means audit by 30 June and return by 30 September.
- Booking only the margin in the sales ledger. The purchase and sale are both real transactions; suppressing either breaks VAT returns and the audit trail.
- Ignoring the rolling VAT threshold. A strong quarter can push a 12-month total over AED 375,000 mid-year.
- Assuming all trading income is 0%. Qualifying-income rules decide; the books must evidence them either way.
FAQ
Do DMCC companies need audited financial statements?
Yes. DMCC requires every member company to upload auditor-signed and stamped audited financial statements and a summary sheet to the Member Portal within six months of the end of each financial year, using an auditor from DMCC's approved list.
What is the penalty for late corporate tax registration in the UAE?
AED 10,000. Under the FTA's waiver initiative, the penalty can be waived if the first tax return or annual declaration is submitted within 7 months of the end of the first tax period.
When does VAT registration become mandatory for a DMCC trading company?
When taxable supplies and imports exceed AED 375,000 over the previous 12 months, or are expected to exceed it within the next 30 days. Voluntary registration is available above AED 187,500.
How long must a DMCC company keep accounting records?
At least 7 years after the end of the tax period to which they relate, per FTA record-keeping requirements confirmed in August 2025.
Is trading income from DMCC automatically taxed at 0%?
No. The 0% rate applies to qualifying income of a Qualifying Free Zone Person; income that fails the qualifying conditions is taxed at the standard 9% rate, and the books must evidence the split.
