How VAT registration works in Czechia
Everything a business owner needs to know about Czech VAT: when registration becomes mandatory, how to register voluntarily, and what filing obligations follow once you are a payer.
01When registration is mandatory
You must register once your turnover exceeds 2 million CZK over 12 consecutive calendar months. You file the application by the 15th of the following month and become a payer from the first day of the second following month.
02Voluntary registration
You can register voluntarily even below the threshold. This is common when your clients are VAT payers who reclaim the tax, so charging VAT does not raise your price for them while you gain the input VAT deduction.
03Filing obligations
As a payer you file a VAT return and a control statement, usually monthly at first. Both are due on the 25th day after the period, and late control statements carry heavy fixed penalties.
04Input and output VAT
You charge output VAT on your sales and deduct input VAT on your business purchases. You pay the difference to the state, or claim a refund when input exceeds output.
