Mark Your Calendar: August 2026 Compliance Due Dates for GST, ITR, TDS & MCA
August 2026 Compliance Calendar: Major Income Tax, ITR, TDS, GST & MCA Deadlines
August 2026 is a crucial month for tax compliance, with several important statutory deadlines applicable to taxpayers, businesses, professionals, companies, and tax deductors. After the busy filing season in July, various obligations under the Income-tax Act, GST laws, MCA regulations, and labour legislations become due during August.
Failure to comply with these deadlines may lead to late filing fees, interest liabilities, penalties, delays in processing returns, or even the loss of certain tax benefits.
Below is a detailed compliance calendar highlighting the key due dates for August 2026.
Income Tax Compliance
7 August 2026 – Due Date for Deposit of TDS/TCS
Tax Deducted at Source (TDS) and Tax Collected at Source (TCS) deducted or collected during July 2026 should generally be deposited with the Central Government on or before 7 August 2026, unless a different timeline applies under the law.
This requirement generally applies to:
- Employers
- Companies
- Partnership firms
- Proprietorship businesses
- Government deductors and other entities responsible for TDS/TCS compliance
31 August 2026 – Last Date to File ITR-3 & ITR-4
The revised Income-tax framework prescribes a separate filing deadline for certain non-audit business taxpayers.
Accordingly, 31 August 2026 is the due date for filing:
- ITR-3 (for eligible taxpayers not subject to tax audit)
- ITR-4 (Sugam)
- Eligible working partners covered under the prescribed provisions
Taxpayers should carefully determine the due date applicable to their category rather than assuming that every return was due on 31 July.
Belated Return for ITR-1 & ITR-2
The original due date for filing ITR-1 and ITR-2 was 31 July 2026, and that deadline has already passed.
Those who could not file within the due date may still submit a Belated Return within the time permitted under the Income-tax Act. However, such filing may attract late filing fees, interest, and other statutory consequences wherever applicable.
Before submitting a belated return, taxpayers should reconcile and verify:
- Annual Information Statement (AIS)
- Form 26AS
- Taxpayer Information Summary (TIS)
- Any outstanding tax demand
- Bank account validation status
Updated Return (ITR-U)
Eligible taxpayers also have the option of filing an Updated Return (ITR-U), provided they satisfy the conditions specified under the Income-tax Act.
The amended provisions now allow updated returns to be filed for a longer period than earlier, subject to payment of the prescribed additional tax and compliance with other statutory requirements.
TDS/TCS Compliance
Quarter 1 TDS/TCS Statements
The due date for filing Quarter 1 TDS/TCS statements for FY 2026-27 was 31 July 2026.
If the statement has not yet been filed, deductors should complete the filing without further delay.
Delayed filing may result in:
- Late filing fee under Section 234E
- Interest, where applicable
- Additional penalties or other legal consequences in eligible cases
Important TRACES Portal Update
The TRACES Portal has introduced revised TDS certificate formats, including Form 131, for Tax Year 2026–27.
Deductors should use the updated portal functionality to download and issue the applicable TDS certificates wherever required.
GST Compliance
For GST-registered businesses, August 2026 is another important month with multiple return filing deadlines that must be monitored carefully.
10 August 2026
Due date for filing:
- GSTR-7
- GSTR-8
11 August 2026
Last date to file:
- Monthly GSTR-1 (for taxpayers filing returns on a monthly basis)
13 August 2026
Due date for:
- GSTR-5
- GSTR-6
20 August 2026
Due date for filing:
- Monthly GSTR-3B
- GSTR-5A (where applicable)
GST Update: E-Way Bill System Changes Postponed
GSTN has deferred the implementation of the proposed enhancements to the E-Way Bill system.
As a result, businesses are not required to make immediate changes to their ERP software or existing operational processes. The revised rollout timeline will be communicated separately by GSTN.
MCA (Ministry of Corporate Affairs)
Company Compliance Facilitation Scheme (CCFS) 2026
A significant MCA compliance opportunity continues to be available through the Company Compliance Facilitation Scheme (CCFS), 2026, which remains open until 31 August 2026.
The scheme allows eligible companies to regularize pending ROC filings and obtain the benefits offered under the scheme, subject to the prescribed conditions.
Companies with outstanding ROC compliances should complete the necessary filings before the scheme expires to avoid missing this one-time compliance opportunity.
Regular ROC Compliances
Apart from the special compliance schemes, companies should also ensure that all routine ROC filings are completed within the prescribed timelines under the Companies Act.
Depending on the nature of the transaction, the commonly applicable ROC forms include:
- DIR-12
- MGT-14
- INC-22
- SH-7
Companies should review their statutory obligations and file the relevant forms on time to avoid additional fees and regulatory non-compliance.
EPF & ESI Compliance
15 August 2026
Employers covered under the respective labour laws should ensure timely remittance of:
- EPF (Employees’ Provident Fund) contributions
- ESI (Employees’ State Insurance) contributions
Timely payment helps employers remain compliant and prevents interest and penalty liabilities.
Checklist Before Filing Your Income Tax Return
Whether filing your original Income Tax Return or submitting a belated return, it is advisable to verify the following documents and records before filing:
- ✅ Annual Information Statement (AIS)
- ✅ Form 26AS
- ✅ Taxpayer Information Summary (TIS)
- ✅ Form 16 or Form 16A (where applicable)
- ✅ Capital Gains Statement
- ✅ Interest Certificates
- ✅ Validated Bank Account Details
Cross-checking these documents helps ensure accurate reporting of income and reduces the chances of receiving tax notices or processing delays.
