How this works

The calendar holds every recurring statutory date for a Private Limited Company, an LLP, a GST-registered business under monthly filing or QRMP, an employer deducting TDS and an individual taxpayer, taken from the Companies Act, the LLP Act, the GST rules and the Income-tax Act 2025 as they stand in September 2026.

When you select an entity and your registrations, it filters to the dates that apply to you and groups them by month, showing the form, who must file it, the penalty and a link to the service that handles it.

Statutory dates that fall on a Sunday or a holiday are shown as the statutory date, because extensions are announced case by case and cannot be assumed; event-driven dates such as AOC-4 and MGT-7A are shown assuming an AGM on 30 September and shift if your AGM is earlier.

The calendar does not know your AGM date, your auditor's timeline or any extension notified after publication, so treat it as the baseline and confirm anything close to the wire with our team.

Questions founders ask about the compliance calendar

Does a company with no revenue need to follow all these dates?

Yes for the ROC and income tax dates: AOC-4, MGT-7A, DIR-3 KYC, DPT-3 where applicable and the income tax return are due regardless of turnover, and the accounts must be audited. GST dates apply only if you are registered, and TDS dates only once you deduct tax.

What if a due date falls on a Sunday?

The statutory date stands unless the department announces an extension, which it sometimes does for portal outages or holidays. File before the weekend rather than relying on an extension; late fees are computed from the statutory date and are rarely waived.

How do the AOC-4 and MGT-7A dates work?

They run from your AGM date: AOC-4 within 30 days and MGT-7A or MGT-7 within 60 days. The calendar assumes an AGM on 30 September, giving 29 October and 28 November. If your AGM is earlier, count from that date instead.

Can I get these dates as reminders?

Clients on our annual filing and GST plans receive reminders and a monthly checklist by WhatsApp and email, and we file most of the forms on this calendar for them. The tool is free to use whether or not you work with us.
