This is the general edition of this guide for Türkiye. It explains how the Tax number (VKN), KDV and annual filing work and names Revenue Administration (GİB) as the place to confirm thresholds and dates. Country-specific figures are added as each edition is reviewed.
The rate
The standard rate in Türkiye is 20%. Some goods and services carry reduced or zero rates and others are exempt. The difference matters: zero-rated sales still let you reclaim the tax on your purchases, exempt sales do not.
Who must register
Registration becomes compulsory once taxable turnover passes the threshold Revenue Administration (GİB) sets, measured over a rolling period. Below it, registration is usually voluntary, which makes sense if your customers are registered businesses that can reclaim what you charge.
How to register
Register with Revenue Administration (GİB) using your Tax number (VKN). Once registered you receive a KDV registration number or certificate, and from that date you must charge KDV on taxable sales, issue compliant invoices and file returns even when nothing is due.
Charging KDV on an invoice
Show the net amount, the KDV rate, the KDV amount and the gross total, with your registration number in the header. Prices quoted to consumers should include KDV; prices quoted to businesses usually exclude it and say so. The Türkiye calculator adds or removes KDV and shows the arithmetic.
Filing and paying
Returns are periodic, most often monthly or quarterly, and report the KDV you charged less the KDV you paid on purchases. The difference is paid to Revenue Administration (GİB) by the return deadline; a repayment is claimed when purchases exceed sales.
Penalties for getting it wrong
Late registration, late returns and late payment each attract penalties and interest with Revenue Administration (GİB). Charging KDV while unregistered is an offence in most countries. If you missed the threshold, register now and declare the back period.
Questions people ask
How do I add KDV to a price?
Multiply the net price by 1.2. A ₺100 sale at 20% carries ₺20 of KDV and totals ₺120.
How do I remove KDV from a total?
Divide the gross by 1.2 to get the net, then subtract to find the tax. Dividing, not taking a percentage off, is the step people get wrong.
Should I register voluntarily?
If most of your customers are registered businesses, yes: they reclaim what you charge and you reclaim what you pay. If your customers are consumers, registration raises your prices by the tax rate or cuts your margin.
What if I am not registered?
Do not charge KDV and do not show a KDV line. State on the invoice that no KDV was charged. The generator prints that line when the toggle is off.
