When is the UAE Corporate Tax return due?

Within nine months of the end of the relevant tax period, and the tax is payable within the same window. A December year-end therefore files and pays by 30 September of the following year; a June year-end by 31 March. There are no provisional or instalment payments in the standard regime — one return, one payment, nine months. Diarise it from the financial-year end, not from any FTA reminder, because none is owed to you.

What is the penalty for late Corporate Tax registration?

AED 10,000. Every taxable person — including free-zone companies expecting to pay 0% and businesses with no profit — must register for Corporate Tax. Registration deadlines were staggered by licence-issuance month, and most have now passed, so an unregistered entity is typically already exposed. The FTA has run waiver windows for late registrants who file promptly; if you are unregistered, the cheapest moment to fix it is immediately.

What are the penalties for filing or paying late?

Late filing accrues a fixed monthly penalty — AED 500 per month (or part month) for the first twelve months, rising to AED 1,000 per month thereafter. Late payment separately accrues an annual-rate penalty on the unpaid tax (14% per annum, applied monthly). The two stack: a return that is both unfiled and unpaid builds fixed penalties and interest-style penalties simultaneously, which is why a return should be filed on time even when cash for the payment is tight.

Do I have to file if my company made no profit or pays 0%?

Yes. Registration and filing obligations apply regardless of the rate you expect to pay: loss-making companies file (and preserve their carried-forward losses by doing so), Qualifying Free Zone Persons file with audited accounts as a condition of the 0% rate, and Small Business Relief must be claimed in a filed return — it is an election, not an exemption that applies by silence.

What records must a UAE business keep for Corporate Tax?

Records and documents supporting the return for seven years from the end of the tax period — financial statements, ledgers, transfer-pricing documentation and the workings behind adjustments and elections. QFZPs must maintain audited financial statements, and audit requirements now extend to larger businesses generally. Penalties apply to record-keeping failures independently of whether any tax was underpaid.

What are the most common first-period mistakes?

Missing registration entirely (the AED 10,000 letter arrives eventually); assuming free-zone status means no obligations; electing Small Business Relief without checking eligibility or realising it forfeits loss carry-forward; filing without transfer-pricing disclosure when related-party dealings exist; and treating the nine-month deadline as movable. Every one is avoidable with a calendar and an hour of advice at year-end rather than an objection after assessment.

UAE Corporate Tax Deadlines & Penalties: The Compliance Calendar That Bites (2026)

In one line

Register (or it's AED 10,000), file and pay within nine months of year-end, keep records seven years — and file even at 0%, because QFZP status, loss carry-forward and Small Business Relief all live inside the return.

UAE Corporate Tax was designed to be light on rate and firm on process. Most of the money the FTA collects in these early years will come from process failures, not tax disputes.

The calendar

Obligation	Deadline	Failure costs
Registration	Staggered by licence month — mostly passed	AED 10,000
File return	9 months after tax-period end	AED 500/mo (yr 1), then AED 1,000/mo
Pay tax	Same 9-month window	14% p.a. on unpaid amounts
Keep records	7 years from period end	Independent penalties

File even when cash is tight. Filing and payment penalties are separate and stack. Filing on time stops the fixed monthly penalty even if payment follows late — the reverse order is the expensive one.

Registration: the AED 10,000 letter

Every taxable person registers — free-zone companies expecting 0%, dormant-ish entities, loss-makers, and natural persons over the AED 1m business-turnover line. Deadlines were staggered by licence-issuance month and have mostly passed; the FTA has periodically offered waivers for late registrants who file promptly. If you're unregistered, today is the cheap day. The mechanics are in our registration walkthrough.

Why 0% still means filing

QFZPs — the 0% rate is conditional on filing with audited accounts and full compliance.
Loss-makers — carried-forward losses are preserved through filed returns.
Small Business Relief — an election made in the return (and one that forfeits loss carry-forward — check before ticking; see the SBR guide).
Related-party dealings — the transfer-pricing disclosure travels with the return.

The first-period mistakes we keep seeing

Missing registration entirely; assuming free-zone means exempt; electing SBR without checking eligibility or consequences; omitting the TP disclosure; missing the nine-month date because "the accountant has it"; and discarding records that must live seven years. Each is an hour of prevention or a season of objection.
