It's a pass-through tax. Once registered, you collect VAT/GST from clients on your invoices (output tax), reclaim the VAT/GST you paid on business expenses (input tax), and remit the difference to the tax authority. The end consumer bears the cost; you're the collection agent. The golden rule: registered freelancers should never let VAT come out of their margin — it's added to prices or already inside them by design.

It depends on turnover and country. Mandatory once you cross the threshold: UK £90,000 (rolling 12 months), Canada C$30,000, Australia A$75,000, India ₹20 lakh (services), UAE AED 375,000, Pakistan PKR 10,000,000 (general threshold). Below that, registration is usually voluntary — and often worthwhile, because it lets you reclaim input tax on equipment and software. The calculator's verdict compares your turnover to the threshold automatically.

Input VAT is the tax embedded in things you buy for the business: laptops, monitors, software subscriptions, subcontractor invoices, coworking fees. Once registered, you claim it back on your VAT/GST return, offsetting it against the output tax you collected. Keep every receipt — no receipt, no reclaim. This is why the calculator asks for it: £2,000 of input VAT is £2,000 off your bill, which for many freelancers exceeds the admin cost of filing.

Often yes, if you have significant input VAT (big equipment purchases, paid subcontractors, software stack) or your clients are mostly VAT-registered businesses who reclaim the tax anyway — they don't care that you charge it. Usually no, if your clients are private individuals (they feel the full price increase) and your expenses are minimal. The UAE explicitly offers voluntary registration from AED 187,500. Run both scenarios in the calculator and compare the net payable.

B2B: quote exclusive. Business clients reclaim the tax, so "£5,000 + VAT" is transparent and standard. B2C: quote inclusive. Consumers can't reclaim it, and in many countries consumer prices must legally include tax — "£6,000 including VAT" is what they compare. The danger is quoting inclusive without doing the math: at 20%, a £72,000 inclusive price contains £12,000 of tax you owe. Use the calculator's inclusive mode to see what's really yours.

Exports are usually zero-rated (0%) or out of scope — you don't charge your local VAT/GST, but you can still reclaim input tax. India explicitly zero-rates service exports (with a Letter of Undertaking). Within the EU, the reverse charge often applies to B2B services: the client accounts for the VAT in their country. Rules vary by jurisdiction and client type, so cross-border invoicing is exactly where a local tax professional earns their fee — this calculator models domestic supplies.

You must register when your taxable turnover exceeds £90,000 in any rolling 12-month period — not the tax year, a rolling window, which catches growing freelancers by surprise. You then have 30 days to register and must start charging 20% VAT. The Flat Rate Scheme (a simplified alternative) exists for small businesses but often costs service freelancers more than standard VAT once input tax is reclaimed — model both before choosing.

The federal rate is 5% GST, but most Canadians pay more: Ontario and Atlantic provinces use harmonized HST (13–15%) combining federal and provincial tax, while Quebec adds separate 9.975% QST. You must register once worldwide taxable supplies exceed C$30,000 in a calendar quarter or four rolling quarters. Below that you're a "small supplier" — you can't charge GST/HST but can't claim input credits either. Sources: HelloBooks, TurboTax Canada.

Not necessarily — and this is the calculator's most important caveat. The 18% federal sales tax applies to goods; services in Pakistan are taxed provincially (Punjab, Sindh, KP, Balochistan each have their own sales-tax-on-services regime with different rates and thresholds). Many freelance services fall under provincial rules, and IT/export services often enjoy exemptions. The calculator uses 18% as the headline figure but flags this clearly: verify your province's services rate with a local tax professional before invoicing.

Most freelance services fall under the 18% GST slab. Registration is mandatory above ₹20 lakh aggregate annual turnover (₹10 lakh in special-category states). Services to foreign clients are exports — zero-rated, so you charge 0% but can claim input credits, typically via a Letter of Undertaking (LUT). You'll file GSTR-1 (sales) and GSTR-3B (summary) returns, and e-invoicing applies at higher turnovers. Sources: Taxscan.

The UAE has charged 5% VAT since 2018. Registration is mandatory at AED 375,000 of taxable supplies in 12 months (apply within 30 days — late registration risks a AED 10,000 penalty) and voluntary from AED 187,500. Most freelancers file quarterly on the EmaraTax portal within 28 days of period end. Note 2026 brought a new penalty regime (late payment now 14% per annum under Cabinet Decision 129/2025), so file on time. Sources: Fastlane, Hisabi.

Generally three consequences: (1) the tax authority can demand the uncollected tax out of your own pocket — you can't go back and bill old clients; (2) penalties and interest (the UAE's AED 10,000 late-registration penalty is a vivid example; the UK and others add surcharges); (3) you lose the input tax you could have reclaimed all along. If your turnover is approaching a threshold, track it monthly — the calculator's registration verdict is a good monthly checkpoint, not a substitute for professional advice.
