August 2026: 5 Tax Deadlines You Cannot Miss
August 2026 is packed with income tax, GST, and other compliance deadlines. Missing them means late fees, penalties, and interest. Here are the key dates every salaried person and small business owner must track.
One missed GST filing can attract a ₹50/day penalty — that's more than your morning chai budget adding up fast.
Missing even one compliance deadline in August could cost you penalties
Key Takeaways
Mark August 7 in your calendar as TDS deposit day — if you run a business or are responsible for deducting tax, ensure payment reaches the government before this date to avoid 1.5% monthly interest.
Check whether you owe advance tax for the July–September quarter — if your total tax liability exceeds ₹10,000 this year from any source beyond salary, pay 45% of the estimated amount by August 15.
If you are GST-registered, file GSTR-1 by August 11 and GSTR-3B by August 20 — keep your invoices reconciled in advance to avoid last-minute errors and the ₹50-per-day late fee.
