Tax & Compliance Due Dates in India
Keeping track of income tax, GST, TDS, MCA and other statutory deadlines is essential for individuals, businesses, companies and professionals in India. Missing a compliance due date can result in late fees, interest, penalties, loss of certain tax benefits or additional regulatory complications.
The Shahnawaz and Associates Due Date Calendar brings important monthly tax and compliance deadlines together in one place. Use this page as a central reference to find the latest monthly due dates and then open the relevant month for detailed filing requirements, forms, payment deadlines and compliance categories.
What Compliance Due Dates Are Covered?
The monthly calendars published by Shahnawaz and Associates cover a range of commonly applicable Indian tax and regulatory obligations, including:
Income Tax Due Dates
Important income tax deadlines may include income tax return filing, advance tax instalments, tax payments, audit-related requirements and other applicable income-tax compliances.
The exact deadline depends on the taxpayer’s status, nature of income, applicable provisions and whether the taxpayer is subject to tax audit or other reporting requirements.
GST Due Dates
GST-registered businesses may have recurring filing and payment obligations such as GSTR-1, GSTR-3B and other GST-related returns or statements.
The applicable due date can vary depending on the taxpayer’s registration, filing frequency, scheme and other applicable conditions.
TDS and TCS Due Dates
Businesses and other persons responsible for deducting or collecting tax may need to deposit TDS or TCS within the prescribed time and complete the related return or statement filing requirements.
Keeping track of both payment and return-filing deadlines is important because these are separate compliance obligations.
MCA and Company Law Due Dates
Companies and LLPs may have additional compliance requirements under the Companies Act, LLP Act and related regulatory frameworks.
Depending on the entity and applicable circumstances, these may include annual filings, director-related compliances, declarations, event-based filings and other statutory forms.
PF, ESI and Labour Compliance
Eligible employers may also have recurring obligations relating to provident fund, ESI and other employment-related statutory compliances.
The applicable deadlines depend on the nature of the establishment and the relevant registration or regulatory requirement.
Important Recurring Tax Deadlines in India
Some compliance deadlines occur regularly during the year. However, the actual due date can change because of government notifications, extensions, taxpayer categories or changes in applicable law.
Common recurring compliance dates include:
- 7th of the month: Certain TDS/TCS payment obligations
- 11th of the month: GSTR-1 for many monthly GST filers
- 15th of the month: Certain TDS certificates, PF-related or other recurring compliance obligations
- 20th of the month: GSTR-3B and related GST payment obligations for applicable taxpayers
- Quarterly advance tax dates: Generally June, September, December and March
- Annual income tax return deadlines: Depend on taxpayer category and whether audit or other conditions apply
MCA annual filing deadlines: Depend on the entity type, financial year and applicable statutory requirements
These dates are provided as general guidance. Always check the detailed monthly calendar and the latest notification applicable to your particular compliance.
Why Should You Track Tax Due Dates?
Tax and regulatory compliance is not limited to filing a return before its deadline. Businesses often need to complete several connected activities before the final filing date, including collecting documents, reconciling accounts, verifying transactions, calculating tax liability and reviewing supporting information.
A compliance calendar helps taxpayers and businesses:
- Plan filings and payments in advance
- Avoid unnecessary late fees and interest
- Organise accounting and tax records
- Track multiple statutory obligations
- Identify upcoming deadlines before they become urgent
- Coordinate GST, TDS, income tax and other compliance work
- Reduce the risk of missing important regulatory filings
For businesses with multiple registrations or compliance requirements, maintaining a monthly checklist can make the compliance process considerably easier.
How to Use This Due Date Calendar
Start by selecting the month you want to review. Each monthly calendar provides a detailed list of important compliance dates along with the relevant form, compliance category and applicable description.
Before acting on any deadline, consider whether the requirement applies to your specific taxpayer or business category. Not every deadline applies to every taxpayer.
Where a deadline has been extended or modified by a government notification, the latest applicable notification should be considered.
Important Note About Compliance Deadlines
Tax and regulatory due dates can change because of notifications, circulars, legislative amendments, court decisions, technical issues on government portals or extensions granted by the relevant authorities.
