Do exports count towards the GST threshold?

Yes. Export turnover is part of aggregate turnover even though it is zero-rated.

Is turnover counted per state or for the whole PAN?

For the whole PAN across India. Separate registrations are needed in each state where you supply from, but the threshold is tested on the combined turnover.

When is e-invoicing mandatory?

For businesses whose aggregate turnover exceeded ₹5 crore in any financial year from 2017-18 onwards, for B2B invoices and exports.

Can I rely on this calculator's result for filing?

Use it as a planning estimate. The final figure depends on the tax year's rules and your exact documents, so a CA should review it before you file or pay.

Does the calculator store my data?

No. The calculation runs in your browser and nothing you type is saved. If you want a CA to review it, share your documents through our checklist-led process.

GST Annual Turnover Checker

Aggregate turnover — all taxable, exempt, export and inter-state supplies under the same PAN across India, excluding GST — decides whether you must register and which returns and obligations apply. The registration threshold is ₹40 lakh for suppliers of goods and ₹20 lakh for services (lower in some special-category states), and many businesses must register regardless of turnover.

Registration — goods: ₹40 lakh
Registration — services: ₹20 lakh
QRMP scheme up to: ₹5 crore
