Czech VAT Return: deadlines, filing frequency and the three forms

Monthly or quarterly? How Czech VAT filing frequency works

Your Czech VAT return frequency depends on annual turnover. Taxable persons whose previous-year turnover exceeds CZK 10 million (around EUR 400,000) file monthly. Below that threshold, quarterly filing is allowed but optional: you may still choose monthly filing. If you operate without a local entity, you may be required to appoint a fiscal representative in the Czech Republic to act on your behalf.

Two exceptions matter. A newly registered VAT payer starts with mandatory monthly filing. Moving to quarterly filing is only possible from the second year of registration, on request to the Finanční správa, and only while you remain below the CZK 10 million threshold.

Your filing frequency appears on your VAT registration certificate. If you are not registered yet, read our guide to the Czech VAT number before going further.

The three Czech VAT forms foreign companies need to know

Czech VAT compliance is not limited to one return. For rates, thresholds and key rules, see the VAT in the Czech Republic fact sheet. Filing-wise, it relies on three separate forms, filed separately, each with its own penalty regime.

VAT return (Přiznání k DPH)

The main VAT return reports all taxable transactions for the period: output VAT on sales at the standard rate of 21% or the reduced rate of 12%, deductible input VAT on purchases and any adjustments. The balance determines the amount payable to the Finanční správa or the VAT credit to carry forward.

Deadline: the 25th day after the reporting period, monthly or quarterly. Format: electronic filing only through the Daňový portál, using a data box (datová schránka) or a qualified electronic signature. The official form is 25 5401/A.

VAT Control Statement (Kontrolní hlášení)

The Kontrolní hlášení is an analytical VAT listing that reports purchase and sales invoices line by line above the relevant thresholds. Introduced in January 2016, it allows the Finanční správa to cross-check your data against supplier and customer declarations and detect VAT fraud.

Specific frequency: monthly for legal entities, whatever the frequency chosen for the main VAT return. For natural persons, the Control Statement follows the VAT return frequency.

Deadline: the 25th day after the reporting period. After filing, the Finanční správa may issue a correction request (výzva), and you have 5 working days to respond.

EU Sales List (Souhrnné hlášení)

The EU Sales List is required when you make intra-Community supplies of goods or B2B services subject to reverse charge to customers in other EU Member States.

• Intra-Community supplies of goods: always monthly.
• Intra-EU B2B services: quarterly if you are a quarterly VAT filer providing services only; monthly as soon as goods are involved.

Deadline: the 25th day after the relevant period.

How to file Czech VAT returns through the Daňový portál

All Czech VAT filings are submitted online only. The official portal is the Daňový portál, managed by the Finanční správa. Two access methods are accepted:

• Electronic data box (datová schránka): mandatory for legal entities registered in the Czech Republic.
• Qualified electronic signature: used by foreign entities without a Czech data box.

Step-by-step filing process:

1. Log in to the Daňový portál with your credentials or datová schránka.
2. Select the tax period, month or quarter.
3. Enter output VAT, broken down by rate (21% and 12%).
4. Enter deductible input VAT on purchases.
5. Validate and sign electronically.
6. File the Kontrolní hlášení for the same period, where required.
7. File the Souhrnné hlášení if intra-EU transactions were carried out.

Reverse charge and advance payments: two rules often misapplied

Reverse charge

When you invoice a B2B service to a company registered in another Member State, you do not charge Czech VAT. The customer self-accounts for VAT in its own country. For your Czech filings, this means:

• No Czech output VAT is charged on the transaction.
• The transaction must be reported in your Souhrnné hlášení.
• Your invoice must state "Reverse Charge" or refer to Article 196 of the VAT Directive.

The mechanism also applies to some domestic Czech transactions, including construction, metals and cereals. Check the position with your tax adviser before invoicing.

The three-condition rule for advance payments

An advance payment received before delivery triggers Czech VAT only if, at the time of payment, three conditions are met at the same time:

1. The nature of the transaction is known, with the goods or service precisely identified.
2. The applicable VAT rate is known.
3. The place of taxation is known, in the Czech Republic.

If one of these conditions is missing, VAT becomes chargeable only when the goods are delivered or the service is actually performed. This differs from the French approach, where payment alone is usually enough.

Penalties for late Czech VAT filings

Czech penalties are significant and can stack quickly across the three forms.

Main VAT return (Přiznání k DPH): See our guide on invoicing in the Czech Republic.

• Late payment: 0.05% of the VAT due per day, capped at CZK 300,000.
• Missing return: the Finanční správa may assess the taxable base by default.
