Every Dubai startup must file — whether profitable or not. Here are the exact deadlines, the rates that apply to your stage, and the penalties for missing either filing.
UAE VAT was introduced in January 2018 at a standard rate of 5%. As a Dubai startup, you need to understand three things: when you must register, when you must file, and what VAT you can claim back.
Once your taxable turnover in any 12-month period exceeds this amount, you must register for VAT within 30 days.
Below AED 375,000 but above AED 187,500, you can choose to register voluntarily — useful for reclaiming input VAT on startup costs.
Should you register voluntarily? If your startup has significant upfront costs — equipment, fit-out, marketing spend — voluntary registration lets you claim back the 5% VAT paid on those costs. For many early-stage businesses, this generates a VAT refund in the first year. Fastlane handles VAT registration as part of our accounting service.
UAE VAT returns are filed quarterly via EmaraTax. The return covers the preceding 3-month period and is due on the 28th of the month following the end of the VAT quarter.
| VAT Quarter | Quarter End | Filing Deadline |
|---|---|---|
| Q1 | 31 March | 28 April |
| Q2 | 30 June | 28 July |
| Q3 | 30 September | 28 October |
| Q4 | 31 December | 28 January |
| Offence | Penalty |
|---|---|
| Late VAT return — 1st offence | AED 1,000 |
| Late VAT return — subsequent offence within 24 months | AED 2,000 |
| Late VAT payment — immediate | 2% of unpaid VAT |
| Late VAT payment — after 7 days | 4% of unpaid VAT |
| Late VAT payment — daily after 1 month | 1% daily (max 300%) |
| Failure to register for VAT when required | AED 20,000 |
The late payment daily penalty accumulates fast. On an unpaid VAT liability of AED 50,000, the 1% daily penalty adds AED 500/day after the first month — reaching AED 15,000 in additional penalties within 30 days. The message: never miss a VAT payment date even if you file on time.
UAE Corporate Tax applies to all UAE businesses for financial years starting on or after 1 June 2023. Every UAE company must register for CT and file an annual return — including startups with zero revenue.
| Taxable Income | CT Rate | Notes |
|---|---|---|
| AED 0 – AED 375,000 | 0% | Zero rate band — most early-stage startups pay nothing |
| Above AED 375,000 | 9% | Standard rate on income above the threshold |
| Revenue under AED 3M (any level) | 0% (SBR) | Small Business Relief election available — nil CT liability |
Small Business Relief (SBR): If your startup's revenue is under AED 3 million, you can elect SBR — resulting in zero CT liability for that year. You still need to file the CT return and make the SBR election. Fastlane checks SBR eligibility for every client and makes the election automatically where it applies.
Your Corporate Tax return must be filed within 9 months of your financial year-end. For most companies with a 31 December year-end, this means a 30 September deadline for the previous year's return.
| Offence | Penalty |
|---|---|
| Failure to register for CT | AED 10,000 |
| Late CT return filing | AED 500/month (max AED 20,000) |
| Understated taxable income | 50% of unpaid CT |
| Failure to maintain adequate records | AED 10,000 – AED 50,000 |
Yes. All UAE companies must file a CT return regardless of whether they made a profit or a loss. If you made a loss, the return documents that loss — which can be carried forward to offset future taxable income. Failure to file even a nil or loss return can still trigger penalties.
Yes — but only if they are an FTA-registered tax agent. Fastlane is FTA-registered (TRN: 104218042400003) and files both VAT returns and CT returns on behalf of clients directly via EmaraTax. Always verify that your accounting provider holds a valid FTA registration before authorising them to file on your behalf.
Services provided to clients outside the UAE are generally zero-rated for VAT purposes — meaning you charge 0% VAT and can still recover input VAT on your costs. However, the rules around place of supply are complex, and not all export services automatically qualify for zero-rating. Fastlane reviews your specific business model as part of VAT registration and ongoing filing.
Yes. Free zone companies are subject to the same VAT and CT registration and filing obligations as mainland companies. Free zone companies may qualify for a 0% CT rate on qualifying income as a Qualifying Free Zone Person, but they must still register for CT and file an annual return declaring their qualifying status.
