Frequently Asked Questions
Are my invoice numbers or calculation inputs stored on your servers?
No. Every calculation runs locally in your browser using client-side JavaScript. None of the figures you enter are sent to or stored on our servers.
Why does my reverse GST calculation differ by 1 rupee from a printed invoice?
Under Section 170 of the Indian CGST Act, tax amounts are rounded to the nearest rupee (50 paise or more rounds up). Discrepancies usually happen when billing software rounds line items individually rather than at the invoice subtotal level.
Can you provide personalized tax advice or file returns for my business?
No. TrueGST is strictly an arithmetic estimation tool. We do not provide formal tax or accounting advice. For statutory filings or compliance disputes, please consult a licensed Chartered Accountant or tax professional.
