Work out a GCC deadline

Many GCC deadlines depend on the tax period or financial year assigned to your business. UAE VAT periods, for example, are staggered by the Federal Tax Authority. Choose an obligation, enter your period end date, and we'll apply the published rule.

How deadlines work in each country

There is no single GCC-wide tax deadline system. Each country sets its own taxes, periods and portals, so treat each one separately.

Please read. This calendar is general information, not tax advice, and not a substitute for the official notifications. Dates can be extended or changed by the authorities at short notice, and a weekend or holiday does not automatically extend an Indian due date unless notified. Always confirm the date and conditions that apply to you on the official portal before filing or paying.

ADR Financial Consultancy is independent and is not affiliated with the Income Tax Department, GSTN or any GCC tax authority. GST and TDS support from ADR relates to India only. We do not file returns in GCC countries.

Nothing you select here is stored or sent anywhere. Calendar files are created in your browser. The optional full Income Tax Department list is loaded from ADR’s calendar service, which copies the official e-filing portal calendar each day. Official wording is reproduced, and each entry has its own conditions.
