The Short Answer: Yes, Filing Is Mandatory — Even with Zero Activity
If your company is registered for corporate tax in the UAE, you must file a CT return for every single tax period — regardless of whether you had any revenue, any expenses, any employees, or any business activity whatsoever. Zero activity does not mean zero filing obligation.
This catches thousands of business owners every year. They set up a free zone company, got their trade licence, registered for corporate tax (because it's mandatory), and then either never started trading or paused operations. They assume that because nothing happened, there's nothing to file. Then the penalties start accumulating.
The late filing penalty for corporate tax is AED 500 per month starting from the day after the filing deadline. There is no warning, no reminder, and no grace period. The FTA's system auto-applies the penalty. After 12 months of not filing a nil return, you owe AED 6,000 in penalties — for a return that would have shown AED 0 in tax payable and taken 10 minutes to submit.
How the Penalty Accumulates — The Math
Let's say your company has a December year-end. Your FY2025 CT return (Jan–Dec 2025) is due by 30 September 2026. If you don't file:
| Month After Deadline | Date | Cumulative Penalty (AED) |
|---|---|---|
| Month 1 | October 2026 | 500 |
| Month 2 | November 2026 | 1,000 |
| Month 3 | December 2026 | 1,500 |
| Month 6 | March 2027 | 3,000 |
| Month 12 | September 2027 | 6,000 |
| Month 24 | September 2028 | 12,000 |
And if you have multiple unfiled periods — say FY2023 and FY2024 and FY2025 — each period has its own penalty running independently. Three years of unfiled nil returns can easily reach AED 18,000+ in penalties.
Compare that to the cost of actually filing: Fastlane files CT returns from AED 249 per period. The maths speaks for itself.
What to File: Small Business Relief (SBR) — The Zero-Tax Return
If your company had zero revenue — or revenue below AED 3 million — you can elect Small Business Relief (SBR) on your CT return. Here's what it does:
When you elect SBR, your taxable income is deemed to be zero. That means zero corporate tax payable, regardless of your actual profit or loss. It's essentially a nil return with a legal basis.
SBR Eligibility
To qualify for Small Business Relief, your company must meet these conditions:
Revenue threshold: Your total revenue for the tax period must be AED 3 million or less. For a company with zero activity, this is obviously met (AED 0 revenue).
UAE resident taxable person: Your company must be a UAE resident for corporate tax purposes. This covers all mainland and free zone companies.
Not a qualifying free zone person (QFZP): If your company has elected to be taxed as a Qualifying Free Zone Person at 0% on qualifying income, you cannot simultaneously elect SBR. However, most dormant free zone companies haven't elected QFZP status, so this isn't usually a barrier.
Tax period: SBR is available for tax periods starting on or after 1 June 2023 and applies until 31 December 2026 (based on current rules — may be extended).
✅ Dormant company? Zero revenue? No employees? No bank transactions? You almost certainly qualify for SBR. Elect it on your CT return, submit zeros across all fields, and you're compliant. No tax payable. No penalty. Takes 10 minutes with a tax agent or accountant.
How to File a Nil CT Return — Step by Step
Step 1: Log into EmaraTax (eservices.tax.gov.ae) and navigate to your Corporate Tax dashboard.
Step 2: Open the CT return for the relevant tax period. You'll see the return form with fields for revenue, expenses, taxable income, and tax payable.
Step 3: Elect Small Business Relief. There's a specific field/checkbox on the return to indicate you're electing SBR for this period.
Step 4: Enter zeros for revenue, cost of revenue, expenses, and other fields. With SBR elected, taxable income is deemed zero and tax payable is zero.
Step 5: Review and submit. The return is filed. No payment is due. You receive an FTA confirmation reference.
That's it. The entire process takes less time than reading about the penalty you'd face for not filing.

What If You've Already Missed the Deadline?
If you've missed one or more CT filing deadlines, here's what to do:
File immediately. The penalty accumulates monthly. Every day you wait adds to the total. Filing stops the clock for that tax period.
File all outstanding periods. Each unfiled period has its own independent penalty. If you have 2–3 periods outstanding, file them all in one go.
Consider a penalty waiver. If there are circumstances that justify a waiver — such as the FTA retroactively changing your first tax period, or you being a newly registered company that qualifies for the FTA's late registration waiver initiative — you may be able to get the penalties reversed.

Then decide: keep filing or deregister. If your company will remain dormant permanently, filing nil returns every year is an ongoing cost and hassle. CT deregistration (from AED 399) stops the filing obligation entirely. But you must file all outstanding returns and pay all penalties before the FTA will approve deregistration. Read: penalties must be paid before deregistration →
When Is the CT Filing Deadline?
The deadline is 9 months after the end of your financial year:
| Financial Year End | Filing Deadline |
|---|---|
| 31 December 2024 | 30 September 2025 |
| 31 December 2025 | 30 September 2026 |
| 31 March 2025 | 31 December 2025 |
| 30 June 2025 | 31 March 2026 |
The deadline is the same whether your company earned AED 10 million or AED 0. There is no "dormant company exemption" in UAE corporate tax law.
"But My Company Never Even Started Trading…"
We hear this constantly. Business owners set up a free zone company for a visa, or to hold assets, or with plans that never materialised. The company has a trade licence but has never issued an invoice, never hired anyone, and sometimes doesn't even have a bank account.
It doesn't matter. If the company is registered for corporate tax — which is mandatory for virtually all UAE companies — a CT return is due for every tax period. The FTA doesn't distinguish between "active trading company" and "dormant shell company." Both must file.
The silver lining: filing is easy and cheap for dormant companies. SBR election, zeros across the board, submit. AED 249 with Fastlane. Get it done today →
If your company should be registered but isn't, the late CT registration penalty is AED 10,000. However, the FTA's waiver initiative means this penalty is waived if you file your first CT return within 7 months of your first tax period end. Don't wait — register now and file.
