Compliance Calendar for Pvt Ltd Companies 2026#
The corporate veil of a Private Limited Company offers tremendous protection to its founders, limiting their personal liability. However, this protection is granted in exchange for radical transparency. A Private Limited Company is scrutinized by the Ministry of Corporate Affairs (MCA), the Income Tax Department (CBDT), the GST Network (CBIC), and labor authorities (EPFO/ESIC).
Missing deadlines across these silos results in a devastating combination of late fees, penal interest, disabled DINs, and blocked E-way bills.
To keep your business running smoothly, here is the master statutory compliance calendar for the calendar year 2026.
Part 1: Monthly Recurring Compliances#
These are the operational deadlines that your accounts team must hit every single month.
| Date | Authority | Compliance Requirement |
|---|---|---|
| 7th | TDS / TCS | Deposit the TDS/TCS deducted in the previous month. |
| 11th | GST | File GSTR-1 (Outward Supplies) for the previous month (for regular taxpayers). |
| 13th | GST | Upload B2B invoices via IFF (for QRMP scheme opt-ins). |
| 15th | Payroll | Deposit PF (Provident Fund) and ESI contributions for the previous month. |
| 20th | GST | File GSTR-3B (Summary and Tax Payment) for the previous month (for regular taxpayers). |
Part 2: Quarterly Recurring Compliances#
These deadlines close out the financial quarters (June, September, December, March).
| Quarter Ending | TDS Return (Form 24Q, 26Q, 27Q) Due Date | GST Return (GSTR-1 for QRMP) Due Date | Advance Tax Installment Due Date |
|---|---|---|---|
| Q1 (June 30) | July 31 | July 13 | June 15 (15% of total tax) |
| Q2 (Sept 30) | October 31 | October 13 | September 15 (45% of total tax) |
| Q3 (Dec 31) | January 31 | January 13 | December 15 (75% of total tax) |
| Q4 (Mar 31) | May 31 | April 13 | March 15 (100% of total tax) |
(Note: Issue Form 16A TDS certificates within 15 days of filing the quarterly TDS returns).

Conclusion#
Relying on memory to track these deadlines is a guaranteed recipe for failure. The most successful Private Limited companies integrate this calendar directly into their project management software (like Asana or Jira) and set automated alerts 15 days prior to the due date, ensuring their CAs have the necessary data well in advance.
