03FAQs

Goods & Services Tax — frequently asked questions

Who must register for GST in India?
Businesses with turnover above ₹40 lakh (goods) or ₹20 lakh (services), inter-state suppliers, and e-commerce sellers must register — in some cases regardless of turnover. We'll confirm your obligation free.
How long does GST registration take?
Usually 3–7 working days after a complete application, subject to Aadhaar authentication and departmental verification.
What are the GST return due dates?
GSTR-1 and GSTR-3B are typically due on the 11th and 20th of the following month; QRMP taxpayers file quarterly. We track every deadline so you never miss one.
What happens if I miss a GST return?
Late filing attracts a late fee (₹50/day, ₹20 for nil returns) plus 18% interest, and can block your e-way bills and input tax credit until you file.
Should I register for GST voluntarily?
Voluntary registration lets you claim input tax credit and sell to GST-registered buyers who prefer compliant vendors — often worth it even below the threshold.
What is a LUT and who needs to file it?
A Letter of Undertaking lets exporters and SEZ suppliers ship goods/services without paying IGST. It's filed annually at the start of each financial year.
What is GSTR-9 and who files it?
GSTR-9 is the annual GST return consolidating all monthly/quarterly returns, mandatory for regular taxpayers above the prescribed turnover limit.
