FAQ: Compliance Workflow

What is the GST Compliance Hub?

The GST Compliance Hub is a central dashboard and knowledge base on TheGSTCalculator.in that organizes all Phase 6 evergreen guides, checklists, and calculators into a unified workflow for Indian taxpayers.

Is this an official GST portal?

No. TheGSTCalculator.in is an educational platform. All final filings, registrations, and official document generation must be performed on government-notified portals such as the GST Portal, E-Way Bill Portal, and IRP.

Which GST guide should I start with?

If you are new to compliance, start with the "GST Invoice Checklist" for documentation or the "GSTR-3B Checklist" for monthly return filing preparation.

How do I check if e-invoice applies to me?

E-invoicing depends on your aggregate annual turnover (AATO). Use our "E-Invoice Limit Checker" tool to review your applicability based on current government notifications.

How do I review ITC before filing GSTR-3B?

Start by reconciling your purchase register with GSTR-2B using our "2B Reconciler," then check for blocked credits using the "Blocked ITC" guide before claiming credit in GSTR-3B.

What tools can help with GST compliance?

Key tools include the GST Invoice Generator, GSTR-2B Reconciler, ITC Set-Off Calculator, E-Invoice Limit Checker, and GSTR Due Date Finder.

Should I verify details on the official GST portal?

Yes. While our tools provide practical guidance and estimates, official tax liability, credit availability, and due dates should always be verified on official government portals.

Sources & Methodology

This hub provides practical workflows, educational comparisons, and compliance estimates. All calculations and guidance should be verified against official notifications.
