Tips for compliance
- Keep invoice templates for both exclusive and inclusive scenarios—you'll need both for exports.
- Remember that discounts typically reduce the taxable value before GST/VAT is applied. Use the Discount Calculator first, then this tool.
- Create separate ledger entries for collected and input tax—your accountant will thank you.
Why this tax calculator is handy
Whether you're a freelancer billing international clients or a finance analyst computing GST returns, being able to swing between exclusive and inclusive tax calculations is essential. Drop in any amount, pick the applicable slab, and let the calculator show net receipts, tax collected, and total payable.
We include popular presets for GST and VAT regimes, but you can add your own percentage (for cess or state-level variations) and even compare scenarios at the same invoice total.
Workflow tips
- Quote clients exclusive of tax, then toggle to inclusive to double-check the amount they'll actually pay.
- When logging expenses, switch to inclusive mode to extract the eligible input tax credit.
- Combine with the investment calculators to estimate post-tax returns.
Common slabs included
India GST (18%), UK & EU VAT (20%), Australia GST (10%), Singapore GST (9%), Canada GST/HST (13%), plus a custom option. Need more? Duplicate a row with your local rate.
Example
Suppose you sell a $1,000 service in a region with 18% GST. In exclusive mode, gross payable becomes $1,180 and tax recorded is $180. If you must present a round $1,000 invoice inclusive of tax, net receipt drops to $847.46 and tax collected is $152.54. Switch between modes to communicate pricing clearly.
