If you freelance across borders — or even locally once you cross a turnover threshold — GST/VAT becomes your quiet side-job. This is the minimum you actually need to know, without the legalese.
Adding tax vs removing tax (the part everyone gets wrong)
Adding (exclusive pricing): price × (1 + rate). A ₹10,000 project at 18% GST bills ₹11,800.
Removing (inclusive pricing): the tax inside a gross price is gross ÷ (1 + rate) × rate. A $1,180 invoice at 18% contains $180 tax — NOT $212.40. Dividing by (1 + rate) is called the reverse charge calculation, and forgetting it is the most common invoicing mistake we see. Our GST/VAT calculator does both directions, including removing tax from gross amounts.
What your invoice must legally show
- Your business name, address and tax number (GSTIN/VAT number).
- The client's details (and their VAT number for EU B2B reverse-charge).
- Invoice date + sequential invoice number.
- Description, quantity, unit price, net amount, tax rate per line, tax amount, gross total.
- For EU reverse-charge: the phrase "Reverse charge — VAT to be accounted for by the recipient".
You can produce a compliant invoice in two minutes with our free invoice generator — it handles net/tax/gross math live and prints clean PDFs, entirely in your browser.
Thresholds: when registration becomes mandatory
Thresholds vary by country and scheme (India GST registration is turnover-based; the UK's VAT threshold is £90,000 as of 2024; many EU states sit around €35,000–50,000 for domestic supply). Above the threshold, registration isn't optional — and late registration penalties exceed what you saved. When in doubt, ask a local accountant once; it's cheaper than one penalty letter.
Three habits that save freelancers real money
- Separate net and tax from day one — track them in different columns (a spreadsheet or margin calculator helps) so tax money isn't accidentally spent.
- Quote inclusive prices to consumers, exclusive to businesses — and say which one you're quoting in writing.
- Keep invoices sequential and unedited — gaps and doctored PDFs are the first thing audits flag.
