What This Tax Compliance Calendar Covers

India’s tax system runs across multiple departments and regulators. A single business might be filing with the Income Tax Department, GST authorities, the Registrar of Companies, EPFO, and ESIC, all in the same month. That’s a lot to track.

This calendar brings it all into one place.

Who Should Use This Calendar

This resource is built for:

• Business owners managing their own compliance
• CFOs and finance managers at small and mid-sized companies
• Chartered accountants and tax consultants handling multiple clients
• Company secretaries tracking ROC deadlines
• Startup founders who need to know what filings apply to them

How to Read This Guide

The calendar is split by tax category first, then by month. You don’t need to read everything. Jump to the section that’s relevant to your business type. Proprietorships, partnerships, LLPs, and companies each have different obligations, and this guide flags which deadlines apply to whom.

How to Use This Compliance Calendar Tool

The interactive calendar tool at the top of this page lets you filter deadlines by business type, tax category, and month. Here’s how to get the most out of it.

Step 1: Pick Your Business Type

Select from the dropdown: Proprietorship, Partnership/LLP, Private Limited Company, or Public Limited Company. The tool will hide deadlines that don’t apply to your structure. Quick example: a sole proprietor doesn’t need to track ROC filings, so those drop off automatically.

Step 2: Filter by Tax Category

You can view all deadlines together, or filter by:

• Income Tax (ITR, Advance Tax, TDS)
• GST (GSTR-1, GSTR-3B, GSTR-9)
• ROC Filings
• PF and ESI

If you’re an accountant reviewing a client’s GST calendar for the month, filter to GST only. It’s cleaner that way.

Step 3: Set Your Reminders

Use the “Add to Calendar” button next to any due date to export it to Google Calendar or Outlook. Pro tip: set the reminder 7 days before the actual due date. That gives you buffer time if there’s a technical glitch on the portal or if your client takes time to share documents.

Monthly Tax Due Dates at a Glance

Here’s a high-level view of what’s due each quarter in 2026. Detailed breakdowns follow in the category-specific sections below.

January to March 2026

July to September 2026

October to December 2026

Income Tax Due Dates 2026

ITR Filing Deadlines

The standard ITR filing deadline for individuals, HUFs, and firms not requiring audit is 31 July 2026. For companies and taxpayers whose accounts need to be audited, the deadline extends to 30 September 2026. And if you’ve missed those, a belated return can still be filed by 31 December 2026, though you’ll pay a penalty of ₹5,000 under Section 234F.

Advance Tax Installments

Advance tax applies to anyone whose estimated tax liability exceeds ₹10,000 for the year. The schedule runs like this:

• 15 June 2026: At least 15% of annual tax liability
• 15 September 2026: At least 45% of annual tax liability (cumulative)
• 15 December 2026: At least 75% of annual tax liability (cumulative)
• 15 March 2027: 100% of annual tax liability

Missing these installments means you’ll owe interest under Sections 234B and 234C. It adds up fast.

TDS Payment and Return Deadlines

TDS deducted in any month must be deposited by the 7th of the following month. The only exception is TDS deducted in March, which must be paid by 30 April.

Quarterly TDS returns:

• Q1 (Apr-Jun): Due 31 July 2026
• Q2 (Jul-Sep): Due 31 October 2026
• Q3 (Oct-Dec): Due 31 January 2027
• Q4 (Jan-Mar): Due 31 May 2027

Form 16 and Form 16A

Form 16 (for salaried employees) must be issued by employers by 15 June 2026 for FY 2025-26. Form 16A (for non-salary TDS) must be issued within 15 days from the TDS return due date for each quarter. Don’t forget these. Employees need them to file their own returns.

GST Due Dates 2026

GSTR-1 Monthly and Quarterly

GSTR-1 reports your outward supplies. Monthly filers must file by the 11th of the following month. Quarterly filers under QRMP scheme file within 13 days after the end of each quarter.

GSTR-3B Filing Schedule

GSTR-3B is your monthly summary return. It’s due by the 20th of the following month for most taxpayers. Taxpayers in certain states with turnover below ₹5 crore may get extended deadlines of the 22nd or 24th depending on their state classification.

Honestly, just file by the 20th to be safe. The interest at 18% per annum on delayed tax payments isn’t worth it.

GSTR-9 Annual Return

GSTR-9 is the annual GST return covering all of FY 2025-26. The due date for filing is 31 December 2026 for most registered taxpayers. GSTR-9C (reconciliation statement) applies to taxpayers whose turnover exceeds ₹5 crore and is due on the same date.

TDS and TCS Compliance Dates

Here’s a clean summary of recurring TDS/TCS obligations:

Late TDS deposits attract interest at 1.5% per month from deduction date to deposit date. Late filing of returns attracts a fee of ₹200 per day under Section 234E, capped at the TDS amount. These numbers are small per day, but they compound if you’re running multiple deductees.

ROC, PF and ESI Filing Deadlines

ROC Annual Filings

Private limited companies and public limited companies must file annual returns with the Registrar of Companies. The key forms are:

• AOC-4:Filing of financial statements, due within 30 days of the AGM
• MGT-7:Annual return, due within 60 days of the AGM
• ADT-1:Auditor appointment, due within 15 days of AGM

For companies whose AGM falls in September 2026, AOC-4 is typically due by 30 October 2026 and MGT-7 by 29 November 2026. Late filing attracts additional fees that increase over time, so don’t put these off.

PF and ESI Monthly Due Dates

These two are monthly obligations for employers with eligible employees.

Missing PF or ESI payments triggers penalties and damages your employees’ social security records. That’s a compliance risk that goes beyond just money.

Tips for Staying on Top of Tax Deadlines

Here are practical ways to make sure you never miss a date:

1. Build a 7-day buffer.Always target filing 7 days before the actual due date. Portals crash. Clients don’t respond in time. That buffer saves you.
2. Use a shared compliance tracker.A shared Google Sheet or compliance software visible to your whole finance team prevents “I thought you filed it” situations.
3. Set up email and SMS alerts.Most CA firms and compliance tools (including Legalxindia) send reminders automatically. Use them.
4. Reconcile TDS monthly.Don’t wait for quarterly return time to figure out discrepancies. Reconcile Form 26AS every month.
5. Keep a document checklist per filing.Know what documents you need for each return before the due date approaches. Chasing invoices at the last minute is avoidable stress.
6. Track extension notifications from CBDT and GSTN.Deadlines do get extended occasionally. Following official channels means you’ll know before your competitors do.

Pro tip: assign a “compliance owner” for each category in your finance team. One person owns GST. Another owns TDS. No overlap, no confusion.

Frequently Asked Questions

1. What is the last date to file ITR for individuals in 2026?

The standard deadline is 31 July 2026 for individuals, HUFs, and non-audit cases. If your accounts need to be audited, the deadline is 30 September 2026. A belated return can be filed up to 31 December 2026 with a late fee.

2. What happens if I miss the GSTR-3B due date?

You’ll owe interest at 18% per annum on any unpaid tax from the due date. There’s also a late fee of ₹50 per day (₹20 per day for nil returns), subject to a maximum cap. File as soon as possible to minimize the damage.

3. When is the TDS return due for Q1 of 2026?

The TDS return for Q1 (April to June 2026) is due by 31 July 2026. This applies to both Form 24Q (salary TDS) and Form 26Q (non-salary TDS).

4. Do all companies need to file GSTR-9?

GSTR-9 is mandatory for most GST-registered taxpayers. However, taxpayers with annual aggregate turnover up to ₹2 crore have the option to skip it in some years based on government notifications. Always check the latest GSTN circular to confirm applicability for your turnover slab.

5. What is the penalty for not depositing PF on time?

Late PF deposits attract damages ranging from 5% to 25% per annum depending on how delayed the payment is. There’s also a penalty under Section 14B of the EPF Act. On top of that, your employees’ UAN records get impacted.

6. Is there a difference between the GSTR-1 due date for monthly and quarterly filers?

Yes. Monthly filers submit GSTR-1 by the 11th of the following month. Quarterly filers under the QRMP scheme file GSTR-1 by the 13th of the month after the quarter ends. Their monthly invoice uploading happens through IFF (Invoice Furnishing Facility) for the first two months of the quarter.

7. How accurate is this tax compliance calendar?

This calendar is based on current provisions under the Income Tax Act 1961, GST laws, Companies Act 2013, and EPFO/ESIC regulations. Legalxindia’s team updates this page when CBDT, GSTN, or MCA issues extensions or changes. That said, always cross-check critical deadlines with official portals before filing.

8. What is Form 16 and when must employers issue it?

Form 16 is the TDS certificate that employers give to salaried employees. It shows the total salary paid and tax deducted at source during the financial year. Employers must issue Form 16 by 15 June 2026 for FY 2025-26. Employees need it to file their income tax returns accurately.

9. Can I file my ROC returns after the due date?

Yes, but late ROC filings attract additional fees. The MCA charges extra per day of delay on forms like AOC-4 and MGT-7. If a company skips ROC filings for two consecutive years, it risks being struck off the register, which is a much bigger problem to fix.

10. How can Legalxindia help with my tax compliance calendar?

Whether you’re a startup, an LLP, or an established private limited company, the team maps your obligations and sends timely alerts so you don’t have to monitor every portal manually.
