The VakilKaro Brief
The Update
April 2026 brings a packed compliance schedule under both GST and Income Tax laws, with multiple overlapping deadlines.
The Impact
Delays in filings can lead to penalties, ITC blockage, e-way bill restrictions, and even registration issues.
The Action
Plan filings in advance, track key dates, and avoid last-minute rush, especially towards the end of the month.
Income Tax Compliance Deadlines
April begins with immediate obligations, especially for those handling TDS and reporting requirements. The first important date is 7 April 2026. By this date, businesses must upload declarations received in Form 27C and deposit TDS or TCS for March where applicable. For government offices, there is an added requirement that tax deducted without challan must be deposited on the same day.
As the month progresses, compliance becomes more layered. By 14 April 2026, TDS certificates for transactions under sections 194-IA, 194-IB, 194M, and 194S must be issued. These typically relate to property transactions, rent payments, and certain contractual payments, and delays here often lead to disputes with counterparties.
The next set of deadlines falls on 15 April 2026. This includes filing Form 3BB by stock exchanges for client code modifications and similar reporting by recognized associations. In addition, authorized dealers must submit Form 15CC for foreign remittances for the March quarter. These are not routine filings for everyone, but for those covered, they are critical.
The most intense compliance pressure comes at the end of the month. By 30 April 2026, multiple obligations converge. These include filing Form 24G where TDS is deposited without challan, submission of challan-cum-statements for certain TDS sections, and deposit of TDS for the March period by non-government deductors. Uploading of Form 15G and 15H declarations also falls on this date.
Apart from this, there are disclosure requirements for pension funds and sovereign wealth funds, along with filing of Form 61 for reporting Form 60 transactions. The clustering of these deadlines makes the last week of April extremely sensitive from a compliance perspective.
GST Compliance Deadlines
On the GST side, the timeline is structured but equally demanding. The first major deadline is 11 April 2026 for filing GSTR-1 for March. This return captures outward supplies and is the foundation for ITC claims by recipients. Any delay here directly affects buyers and can lead to reconciliation issues.
Following this, attention shifts to GSTR-3B. For taxpayers with turnover exceeding 5 crore, the due date is 20 April 2026. For smaller taxpayers under the QRMP scheme, the due dates differ based on geographical grouping. Group A taxpayers must file by 22 April, while Group B taxpayers have time until 24 April.
Parallel to this, there are other routine but important filings. GSTR-7 and GSTR-8, relating to TDS and TCS under GST, are due on 10 April. Input Service Distributors must file GSTR-6 by 13 April. Non-resident taxpayers providing OIDAR services must file GSTR-5 or 5A by 20 April.
For taxpayers under the composition scheme, CMP-08 for the January to March quarter must be filed by 18 April 2026. Those under QRMP must ensure tax payment through PMT-06 by 25 April.
Towards the end of the month, GSTR-11 must be filed by 28 April by entities holding a Unique Identity Number. Though this applies to a limited category, missing it can delay refunds.
Key Compliance Insights
One of the most important aspects to understand is how interconnected GST filings have become. Filing of GSTR-1 is not just a standalone obligation. It directly feeds into GSTR-3B through auto-population of tax liability and ITC. This means any delay or error in GSTR-1 flows into the next return.
Another important point is system-driven enforcement. Non-filing of returns can lead to blocking of e-way bills, suspension of registration, and restrictions on generating invoices. These are not theoretical consequences anymore; they are automated in the system.
On the income tax side, TDS compliance continues to be closely monitored. Delays not only attract interest and penalties but can also impact deductibility of expenses and trigger notices.
Practical Implications
April is not just about compliance, it is about discipline.
The biggest challenge is not the complexity of individual filings but the clustering of deadlines. Many important due dates fall within a span of ten days. If planning is not done in advance, it becomes very easy to miss something.
Another issue is dependency. GST filings depend on accurate data, reconciliations, and coordination with vendors and clients. Similarly, TDS compliance depends on proper tracking of transactions and timely documentation.
For businesses, the solution is simple but often ignored. Do not wait for deadlines. Spread the work across the month, prepare data early, and keep buffer time for corrections.
Conclusion
April 2026 is a heavy compliance month with very little room for error.
Both GST and Income Tax deadlines are tightly packed, and delays can have cascading effects. From penalties to operational disruptions, the cost of non-compliance is much higher than the effort required to stay compliant.
The takeaway is straightforward. Plan early, file on time, and treat compliance as a continuous process rather than a last-minute task.
