1. VAT — change to the registration threshold
What's changing?
The threshold for mandatory VAT registration is increasing from 1 million CZK to 2 million CZK over the previous 12 months.
Who does this affect?
Positive impact: OSVČ with turnover between 1–2 million CZK no longer need to be VAT payers Potential complications: Loss of entitlement to deduct input VAT
Practical example:
Situation: A graphic design studio with annual turnover of 1.5 million CZK
Before 2025: Mandatory VAT registration
- Output VAT: 315,000 CZK (21%)
- Input VAT: −45,000 CZK (computers, software)
- Amount payable: 270,000 CZK
From 2025: Registration not required
- No output VAT: 0 CZK
- Cannot deduct input VAT
- Saving: approx. 250,000 CZK per year
VAT decision calculator:
STAY NON-VAT REGISTERED IF:
- Turnover < 2 million CZK
- Low input VAT costs (up to 50,000 CZK/year)
- Customers are mostly B2C (non-VAT payers)
REGISTER VOLUNTARILY IF:
- High input VAT costs (100,000+ CZK/year)
- Customers are mostly businesses (VAT payers)
- You're planning investment in machinery/technology
