GSTR-3B & GSTR-5A Returns
These monthly GST returns are crucial for paying taxes and summarizing business transactions completed during May 2026.

1. GSTR-3B (Monthly Summary Return)
Who files it ? Regular taxpayers with an aggregate turnover exceeding Rs 5 Crore, or those with a lower turnover who opted out of the quarterly QRMP scheme.

What is it for ? A self-declared monthly summary return used to report outward supplies (sales), claim Input Tax Credit (ITC), and deposit the final net GST liability.

2. GSTR-5A (For OIDAR Service Providers)
Who files it? Online Information and Database Access or Retrieval (OIDAR) service providers located outside India who provide digital services (like cloud storage, streaming, or online gaming) to unregistered clients in India.

What is it? A simplified monthly return used to declare and pay tax on digital services delivered to Indian consumers.

Penalty for Delay: Missing the June 20 deadline attracts a statutory late fee of Rs 50 per day (Rs 20 per day for NIL returns) for each form. Additionally, delayed tax payments incur interest at 18% per annum on the unpaid tax liability.
