GST Return Filing Checklist for June 2026 | Future Tax

GST compliance checklist for Indian businesses

Every GST-registered person must issue valid tax invoices, file GSTR-1 and GSTR-3B on time, reconcile purchases with GSTR-2B, and pay tax after claiming eligible input tax credit. Annual returns (GSTR-9) summarise the year for many taxpayers.

Common GST mistakes

• Wrong HSN or tax rate on invoices
• Claiming ITC on blocked credits
• Missing reverse-charge entries
• Late filing of returns

Coimbatore businesses in manufacturing and trade should maintain e-way bills and job-work documentation where applicable. Our GST team files returns monthly and supports notice replies.

Due dates and tools

Use the tax calendar 2026 for GSTR-1, GSTR-3B, and annual return deadlines. Estimate invoice tax with the GST calculator before issuing bills to customers.

When to consult a CA

Register before crossing turnover limits, when starting interstate sales, or when buyers require a GSTIN on invoices. Future Tax offers registration, bookkeeping, and return filing from Singanallur with WhatsApp document support.
