Filing Corporate Tax on EmaraTax
To file UAE corporate tax on EmaraTax: log in with your registered credentials, open the corporate tax return for the correct tax period, and confirm the entity and period details before you touch a single field. Enter your taxable income after book-to-tax adjustments, work through the disclosure schedules that apply to your business (not every schedule appears for every taxpayer), apply any elections or reliefs you are claiming, then check the return against your financial statements before you submit and pay. Filing and payment share one deadline — nine months after your financial year-end, so a 31 December year-end usually means 30 September the following year — and there is no separate payment window afterwards. Building the support pack (financials, adjustment schedule, election evidence) before you open the portal is what turns filing into a routine task instead of a last-minute scramble.

Open the corporate tax return
The return sits under your corporate tax registration in EmaraTax, and the portal only shows you the correct filing once the entity and period are confirmed. Rushing this step is the single most common reason businesses end up editing the wrong period or duplicating a submission.
- Log in with your registered credentials and select the corporate tax service.
- Open the corporate tax return for the correct tax period — check the start and end dates match your financial year.
- Confirm entity details, trade licence and TRN before entering any figures.
- Have your computed taxable income and supporting schedules ready before you start.
- Save your progress; EmaraTax lets you return to an in-progress return without losing entries.
Enter, submit and settle
Accuracy in the disclosures matters as much as the totals, because the FTA can query a return long after it is submitted. Work from your finalised financial statements, not draft numbers, and treat every schedule as something to actively confirm rather than skip.
- Enter taxable income and complete every disclosure schedule relevant to your business.
- Apply elections or reliefs you are claiming, such as Small Business Relief, transitional relief or the realisation basis — most cannot be added retroactively.
- Review the return line by line against your financials and adjustment schedule before submitting.
- Submit, then save the acknowledgement — it is your proof of filing if a query arises later.
- Pay the liability at the same time; there is no separate, later payment window.
Build the filing pack first
Logging into EmaraTax before your documents are ready is one of the most common filing mistakes Exiloz sees. The portal moves quickly once you have the numbers, so the real work happens before you log in, not during the session.
- Trade licence, TRN and entity profile details, checked for accuracy.
- Financial statements for the period and the supporting ledgers behind them.
- A clean adjustment schedule reconciling accounting profit to taxable income.
- Free zone, related-party, relief or exemption documentation where any of these apply.
- A note of which schedules apply to your business, so you are not guessing inside the portal.
Common EmaraTax filing mistakes
Most filing problems are procedural, not legal — businesses understand the corporate tax rules but stumble on how EmaraTax presents them. The same handful of mistakes show up again and again.
- Understanding the law but not the portal workflow, which slows down an otherwise straightforward filing.
- Leaving the deadline calculation until the last few weeks before it is due.
- Assuming a nil return, free-zone status or the first-return waiver does not apply without actually checking the conditions.
- Logging into EmaraTax before the supporting documents and adjustment schedule are ready.
- Forgetting that certain elections — Small Business Relief, transitional relief, the realisation basis — must be made inside the return itself and cannot be added later.
Payment, corrections and records
Filing is not the final step. What you do after you submit protects the filing from turning into a penalty later.
- Pay with the return — the tax is due by the same nine-month deadline, and filing without paying still accrues payment penalties.
- If you find an error after submission, correct it through the voluntary disclosure mechanism rather than adjusting the next return quietly.
- Keep the computation, schedules and supporting records for seven years; they are the first thing an FTA audit requests.
- Diarise next year now — registration data, elections and accounting-period settings roll forward and should be reviewed, not assumed correct.
Frequently Asked Questions
For companies filing corporate tax on EmaraTax — from opening the return to settling what you owe.
Where do I file corporate tax?
On the EmaraTax portal, under your corporate tax registration for the relevant tax period. You need to be logged in with your registered credentials and have the correct period selected before you enter any figures.
When is the return due?
Nine months after the end of your financial year — so a 31 December year-end is usually due by 30 September the following year. Payment is due on the same date; there is no separate, later payment window.
Do I need financials first?
Yes. Prepare your financial statements and compute taxable income before you open the return. EmaraTax is built to record a return you have already worked out, not to calculate it for you.
What actually happens inside the EmaraTax return?
You confirm the taxpayer profile and tax period, enter taxable income from your adjustment schedule, work through only the disclosure schedules relevant to your business, apply any elections or reliefs, then review and submit before paying.
What if I discover a mistake after I have submitted?
Correct it through the voluntary disclosure mechanism rather than adjusting a later return. Voluntary disclosure is the formal route the FTA expects, and using it promptly generally limits the exposure compared with leaving an error uncorrected.
How long do I need to keep my filing records?
Seven years. Your computation, schedules and supporting documents are typically the first thing requested if the FTA opens an audit, so they need to be retrievable, not just filed away.
Can Exiloz file it for me?
Yes. We prepare the filing pack, complete every relevant schedule, apply the elections you are entitled to, and submit and settle the return end to end.
