Never miss a compliance deadline. Stay organized, stay compliant, and grow your business with HisabKitab.

Running a business involves much more than managing sales, inventory, and customers. Every month brings important compliance responsibilities, and missing even one statutory deadline can result in penalties, interest, or notices from government authorities.

To help businesses, accountants, finance professionals, and tax consultants stay on track, we've compiled the August 2026 Compliance Calendar, covering important GST, TDS, Professional Tax, Income Tax, and ROC due dates.

Whether you're an MSME, retailer, wholesaler, manufacturer, startup, or service provider, this calendar will help you plan your compliance activities efficiently.

August 2026 Compliance Calendar

Note: Professional Tax requirements and certain statutory deadlines may vary based on state regulations and applicable government notifications. Businesses should verify the relevant requirements before filing or making payments.

August 7 – TDS / TCS Payment

Businesses that have deducted TDS or collected TCS during July 2026 should complete the applicable payment by 7 August 2026.

Before making the payment, businesses should reconcile their accounting records with the relevant TDS/TCS information to minimize discrepancies.

Recommended check:
TDS/TCS records → Accounting entries → Reconciliation → Payment

August 10 – Professional Tax on Salaries

Businesses covered under Professional Tax should review and complete the applicable payment relating to July salaries.

Since Professional Tax is administered by individual states, the applicable due date and compliance requirements may differ across states.

Businesses should therefore verify their respective state requirements before making the payment.

August 11 – GSTR-1 for July 2026

GSTR-1 for July 2026 is due on 11 August 2026 for monthly GST taxpayers.

The return generally contains details relating to:

• Outward supplies

• Sales invoices

• Debit notes

• Credit notes

Maintaining accurate sales and invoice records throughout the month can make GST return preparation significantly more efficient.

August 13 – GSTR-1 IFF for July 2026

Eligible taxpayers registered under the Quarterly Return Monthly Payment (QRMP) Scheme should review their Invoice Furnishing Facility (IFF) requirements for July 2026.

IFF enables eligible QRMP taxpayers to furnish applicable B2B invoice details during the month.

Keeping invoice information updated helps maintain accurate GST records and supports timely availability of invoice details to recipients.

August 15 – TDS Certificates & PF/ESI Returns

15 August 2026 is an important compliance date highlighted in the calendar.

Businesses should review:

TDS Certificates

Issue Form 16A for the April – June 2026 quarter, wherever applicable.

PF & ESI Returns

Applicable employers should also ensure that their PF and ESI-related returns are reviewed and completed within the applicable timeline.

Accurate payroll and employee records are essential for completing these obligations efficiently.

August 20 – GSTR-3B for July 2026

Monthly GST taxpayers need to file GSTR-3B for July 2026 by 20 August 2026.

Businesses should review the following before filing:

• GST liability

• Input Tax Credit (ITC)

• Tax payment details

• Outward and inward supplies

A proper reconciliation of accounting and GST records can help identify discrepancies before the return is submitted.

August 25 – GST Challan Payment

For eligible taxpayers under the QRMP Scheme, 25 August 2026 is an important date for GST challan payment where sufficient ITC is not available for the applicable period.

Businesses should review their GST liability and available ITC in advance to determine the applicable payment requirement.

August 30 – Property TDS Forms

30 August 2026 is highlighted for applicable Property TDS Forms, including:

• Form 26QB

• Form 26QC

• Form 26QD

• Form 26QE – Crypto Assets

Taxpayers covered under these provisions should review the relevant transaction details and complete the applicable forms within the prescribed timeline.

August 31 – Income Tax Returns

The final major date in the August calendar is 31 August 2026, covering applicable Income Tax Returns for FY 2025-26.

The calendar includes returns applicable to:

• Individuals

• HUFs

• Firms not subject to audit

• Individuals/HUFs with business or professional income, where applicable

Before filing, taxpayers should ensure their income details, books of accounts, deductions, tax information, and supporting documents are properly organized.

Why Businesses Should Track Compliance Dates

Compliance management becomes easier when deadlines are planned rather than handled at the last minute.

A structured compliance process can help businesses:

• Reduce the risk of missed deadlines

• Minimize avoidable interest and late fees

• Maintain accurate GST and tax records

• Improve financial record keeping

• Simplify reconciliation before filing

• Keep important documents organized

• Reduce last minute compliance pressure

The key is simple: accurate accounting throughout the month makes compliance easier at the end of the month.
