Before you act

The draft’s ₹10-lakh/₹40-lakh summary is outdated and overbroad; thresholds vary by supply and notified State treatment.
Inter-State service suppliers below the notified threshold may be exempt from compulsory registration.
Small goods suppliers through e-commerce operators may qualify under notified conditions; the old blanket rule is unsafe.
The GST portal entity selection and prompts should be verified live rather than quoted from memory.

Controls

Practical evidence checklist

Keep the governing notification or rule, effective-date note, identity and authority documents, transaction records, calculations, filed forms, payment proof, acknowledgements, notices and responses. Add a short reconciliation explaining every material mismatch. Review continuing duties after approval or filing; many registrations, claims and licences fail later because renewal, reporting, display, record or change-notification duties were ignored.

Need a fact-specific review?

Confirm the effective law, documents, filing route and continuing obligations before relying on general guidance.

Practical questions

Frequently asked questions

Can I rely on the supplied older article?

Use it only as a topic prompt. Verify the law, form, rate, threshold and portal route effective on the relevant date.

What is the safest first step?

Identify the exact facts and search the responsible regulator’s current official material before preparing documents or making a claim.

Do portal acceptance and legal eligibility mean the same thing?

No. Technical acceptance does not cure an ineligible claim, wrong classification or missing evidence.

Should I keep supporting records?

Yes. Preserve calculations, source documents, authority, acknowledgements and later correspondence for the applicable retention period.

When is professional review sensible?

Use one where facts are disputed, money or penalties are material, a deadline is close, or the law has recently changed.
