August often brings a heavy compliance load for Indian businesses. Multiple statutory deadlines fall within a single month. Missing even one date can trigger penalties or interest. This calendar consolidates every major due date for August 2026. It covers GST, ESI, PF, FEMA, Income Tax, MCA, TDS/TCS, and SEBI. Use it to plan filings well in advance.

Why This Month Needs Extra Attention

August 2026 carries added complexity this year. Independence Day falls on 15th August, a Saturday. Consequently, three important deadlines shift to 17th August. Additionally, two new income tax forms apply for the first time. Form 131 replaces the old Form 16A. Form 141 replaces four separate TDS forms. Businesses must update their filing workflows accordingly.

GST Compliance Deadlines

GST remains the busiest compliance area every month. Several returns and payments fall due throughout August.

• 7 August: Due date for depositing TDS and TCS under GST provisions, where applicable.
• 10 August: GSTR-7 and GSTR-8 become due for July 2026 transactions.
• 11 August: Monthly GSTR-1 is due for regular taxpayers above the turnover threshold.
• 13 August: GSTR-5 and GSTR-6 fall due. QRMP taxpayers can optionally use the IFF facility.
• 20 August: Monthly GSTR-3B and GSTR-5A become due for July 2026.
• 25 August: QRMP taxpayers with insufficient input tax credit must pay tax through Form PMT-06.

Notably, QRMP taxpayers do not file GSTR-3B in August. Their quarterly return falls due in October instead. However, they must still clear any tax shortfall through PMT-06. Skipping this step attracts interest, even without a monthly return obligation.

TDS and TCS Deadlines

Tax deducted and collected at source requires timely deposit and reporting.

• 7 August: Deposit of TDS and TCS collected during July 2026.
• 17 August (shifted from 15 August): Issue Form 131, the new TDS certificate for non-salary payments made during April to June 2026.
• 31 August (shifted from 30 August): File Form 141, the unified challan-cum-statement covering property purchases, high rent payments, and contractor or professional payments.

Form 131 now replaces the familiar Form 16A. Similarly, Form 141 merges four older forms into one. These include Forms 26QB, 26QC, 26QD, and 26QE. Businesses should update their internal references immediately. Otherwise, teams risk filing under outdated form numbers.

Income Tax Deadlines

Income tax obligations extend beyond TDS deposits this month.

• 31 August: Income Tax Return filing deadline for non-audit business taxpayers. This includes individuals, HUFs, firms, and LLPs filing ITR-3 or ITR-4 for FY 2025-26.

This deadline shifted from the earlier 31 July date. Consequently, many taxpayers now have extra preparation time. Still, businesses should reconcile their books early. They must also match TDS records with Form 26AS and the AIS. Waiting until the last week increases the risk of portal congestion.

ESI and PF Deadlines

Employers registered under labour welfare schemes must meet monthly obligations.

• 17 August (shifted from 15 August): Deposit Provident Fund contributions and file the Electronic Challan-cum-Return for July 2026.
• 17 August (shifted from 15 August): Deposit ESI contributions and file the corresponding return for July 2026.

Both deadlines originally fall on 15 August. However, this date coincides with a national holiday. Therefore, the effective deadline moves to the next working day. Employers should reconcile payroll data well before this shifted date. Waiting until the last moment could create banking delays.

FEMA Compliance Deadlines

Companies with foreign borrowings must also report their transactions.

• Within 7 working days of month-end: Borrowers must submit Form ECB-2 through their authorised dealer bank. This form reports actual external commercial borrowing transactions for July 2026.

Businesses should confirm the exact working-day count carefully. The Independence Day holiday may affect this calculation. Local bank holidays could further adjust the reporting window. Therefore, companies should coordinate closely with their authorised dealer bank.

Companies Act and MCA Deadlines

Corporate compliance under the Companies Act depends heavily on individual triggers.

• Ongoing: Companies whose Annual General Meetings fell in June or July 2026 should track their AOC-4 and MGT-7 filing timelines. Both forms are generally due within 60 days of the AGM date.
• 31 August: The Companies Compliance Facilitation Scheme, 2026 window closes. This scheme offers reduced additional fees for specified delayed filings.

Corporate filing dates vary based on entity type and AGM timing. Therefore, companies should verify their specific deadlines individually. This section works best as a planning reminder, not a fixed date list.

SEBI Compliance Deadlines

Listed entities face additional disclosure requirements under SEBI regulations.

• 14 August (subject to confirmation): Quarterly financial results for April to June 2026 are generally due within 45 days of quarter-end under Regulation 33.

Since Independence Day falls close to this date, listed companies should confirm the exact deadline. Consulting compliance counsel helps avoid last-minute confusion. Additionally, companies should review Regulation 32(1) deviation or variation statements if applicable.

Key Date Shifts to Remember

Three deadlines move this month due to holidays and weekends.

• Form 131, PF deposit, and ESI deposit shift from 15 August to 17 August.
• Form 141 shifts from 30 August, a Sunday, to 31 August.
• The non-audit ITR deadline remains fixed at 31 August, coinciding with Form 141.

This overlap creates a compressed final week. Businesses should avoid clustering all filings into the last two days.

Practical Tips for Smooth Compliance

Careful planning prevents last-minute compliance stress. Consider these practical steps throughout August.

• File GSTR-1 before attempting GSTR-3B, since the latter auto-populates from the former.
• Treat 13 August as an internal deadline for PF, ESI, and Form 131 preparation.
• Reconcile payroll data early to avoid banking delays around the shifted 17 August date.
• Confirm your applicable GSTR-3B filing group, since some taxpayers follow staggered schedules.
• Track official portal notifications for GSTN, Income Tax, EPFO, ESIC, and MCA21 throughout the month.

Conclusion

August 2026 combines routine monthly filings with new procedural changes. Businesses must track GST, TDS, ESI, PF, FEMA, MCA, and SEBI deadlines carefully. Holiday-related shifts add extra complexity this year. Preparing early, verifying official notifications, and avoiding last-minute filings remain the safest approach. Consulting a qualified tax or compliance professional can further reduce risk.
