Reverse Charge VAT: When and How to Use It

If you work in construction, trade in metals, electronics, or grain, you probably encounter the reverse charge VAT mechanism on a daily basis. This special VAT regime transfers the obligation to declare and pay VAT from the supplier to the customer. For many business owners, it's a confusing mechanism that leads to mistakes in invoicing and VAT returns. In this article, we'll take a detailed look at when the regime applies, how to issue an invoice correctly, and everything you need to report to the tax authority.

What Is Reverse Charge VAT?

Under the standard VAT regime, the principle is straightforward: the supplier issues an invoice with VAT, collects the VAT from the customer, and remits it to the tax authority. Under the reverse charge mechanism, this process is flipped.

Why This Regime Exists

The reverse charge mechanism was introduced as a tool to combat VAT fraud, particularly so-called carousel fraud. In these schemes, a supplier collects VAT from the customer but never remits it to the state, while the customer claims it as a deduction — leaving the state out of pocket. By shifting the obligation to the customer, the risk of fraud is eliminated — there's nothing to withhold, because the supplier never collects VAT in the first place.

Legal Basis

The domestic reverse charge mechanism is governed by Act No. 235/2004 Coll., on VAT, specifically Sections 92a to 92i. The basic conditions are set out in Section 92a:

• The regime applies only between VAT-registered entities
• The supply must have its place of supply in the Czech Republic
• The supply must be one of those explicitly listed in the law

Which Sectors Use Reverse Charge

The VAT Act distinguishes between a permanent and a temporary reverse charge regime. Let's walk through both.

Permanent Regime (§ 92b – § 92d)

These commodities fall under reverse charge on a permanent basis, with no time limit:

Temporary Regime (§ 92e – § 92g)

The temporary regime is established by government decree and its validity depends on authorisation from the EU Council. It is currently extended until the end of 2026.

Construction and Assembly Work — The Most Common Case of Reverse Charge

Construction is by far the most common sector where reverse charge is applied in practice. Let's look at it in detail.

What Counts as Construction Work

The reverse charge regime covers work classified under the CZ-CPA (Classification of Products by Activity) codes 41 to 43:

Section 41 — Buildings and building construction:

• Construction of residential and non-residential buildings
• Property development

Section 42 — Civil engineering works and their construction:

• Roads, railways, bridges, and tunnels
• Utility networks (electricity, gas, water)
• Other civil engineering structures

Section 43 — Specialised construction activities:

• Demolition and site preparation
• Electrical installation, plumbing, and other installation work
• Plastering, painting, and glazing
• Floor and wall tiling and covering
• Steel structural element assembly
• Building insulation
• Roofing

What Does NOT Count as Construction Work

Be careful with supplies that may look like construction work at first glance but do not fall under reverse charge:

• Supply of building materials without installation (this is a supply of goods, not construction work)
• Project documentation and construction supervision (services, not construction work)
• Cleaning services after construction
• Manufacturing of building components in a workshop (e.g. window manufacturing), unless it also involves on-site installation
• Architect and engineer services
• Rental of construction equipment without an operator

Practical Examples from the Construction Sector

How to Issue an Invoice Under Reverse Charge

A reverse charge invoice differs from a standard invoice in several important ways.

Mandatory Invoice Requirements

Recommended Invoice Wording

The following text is recommended for inclusion on the invoice:

"Reverse charge regime. The recipient of the supply is required to calculate and declare the VAT amount under Section 92a of Act No. 235/2004 Coll., on Value Added Tax."

Obligations of the Supplier

As the supplier under the reverse charge regime, you have the following obligations:

1. Issue the Invoice

Issue an invoice without VAT, but with all mandatory details, including the reverse charge statement and the applicable VAT rate.

2. Record for the VAT Control Statement

Report the reverse charge supply in the VAT control statement under section A.1. (supplies made under the reverse charge regime).

3. VAT Return

Report reverse charge supplies in your VAT return on line 25 (tax base for supplies where the recipient is obliged to declare VAT).

4. VAT Records

Maintain VAT records under Section 92a(5), which must include:

• Customer's VAT number (DIČ)
• Date of taxable supply
• Tax base
• Scope and subject of supply

Obligations of the Customer (Recipient)

As the customer receiving a reverse charge supply, you have the following obligations:

1. Calculate the VAT

On the received document (or in your own records), calculate the VAT amount based on the applicable rate.

2. Declare Output VAT

Declare the VAT in your VAT return as output tax — lines 10 and 11 (depending on the rate).

3. Claim Input VAT Deduction

If you are entitled to deduct, simultaneously claim the VAT as input tax — lines 43 and 44.

4. Record for the VAT Control Statement

Report the supply in the VAT control statement under section B.1. (supplies received under the reverse charge regime).

VAT Control Statement and Reverse Charge

The VAT control statement is the key document in which reverse charge supplies are reported. Completing it correctly is essential, as the tax administration matches data from suppliers and customers.

Control Statement Sections for Reverse Charge

Mandatory Information in the Control Statement

For each reverse charge supply, you must include:

• VAT number (DIČ) of the trading partner
• Tax document reference number
• Date of taxable supply
• Tax base
• Supply type code (important for correct classification)

Supply Type Codes

Cross-Border Reverse Charge

In addition to the domestic reverse charge, there is also a cross-border reverse charge that applies to trade between EU member states.

Acquisition of Goods from the EU

If, as a VAT-registered entity, you acquire goods from another EU member state from a person VAT-registered in that other state, you declare VAT in the Czech Republic (reverse charge). The EU supplier invoices without VAT, and you declare Czech VAT as output tax while simultaneously claiming it as a deduction.

Receipt of Services from the EU

Similarly, when receiving a service from a person not established in the Czech Republic (an EU supplier), where the place of supply is in the Czech Republic under Section 9(1) (the basic rule for B2B services), you declare VAT in the Czech Republic.

Differences from Domestic Reverse Charge

Common Mistakes and Pitfalls

1. Applying Reverse Charge to a Non-VAT-Registered Customer

The most common mistake is issuing an invoice without VAT to a customer who is not VAT-registered. If the customer is not registered for VAT, you MUST invoice using the standard regime with VAT.

Prevention: Always verify the customer's VAT registration status in the VAT payer register on the Financial Administration website before issuing an invoice.

2. Incorrectly Showing VAT on the Invoice

If you mistakenly show a VAT amount on a reverse charge invoice, that tax becomes incorrectly charged VAT and the supplier must remit it. However, the customer cannot deduct it.

3. Incorrect Classification of Construction Work

Some work on the borderline between construction and non-construction activities creates uncertainty about whether to apply reverse charge. Typical edge cases include:

• Supply with installation — if the installation takes place on the property and is the main element of the supply, it is generally treated as construction work
• Post-construction cleaning — removal of construction debris may qualify as construction work; routine cleaning does not
• Repairs and maintenance — repairs to immovable property (painting, door replacement, roof repair) fall under reverse charge; repairs to movable goods do not

4. Wrong Code in the Control Statement

Using the wrong supply type code in the VAT control statement leads to mismatches during reconciliation and subsequent queries from the tax authority.

5. Customer Failing to Declare VAT

A customer who receives a reverse charge invoice must actively declare the VAT as output tax. Overlooking this creates a risk of additional tax assessments and penalties.

When Reverse Charge Does NOT Apply

For completeness, it's important to note the situations where reverse charge does not apply, even if it might seem relevant at first glance:

• The customer is not VAT-registered — the regime applies exclusively between VAT-registered entities
• Place of supply is outside the Czech Republic — domestic reverse charge does not apply to supplies with a place of supply in another country
• Supply falls below the price threshold — for electronics, cereals, and metals, reverse charge only applies above CZK 100,000 excl. VAT on a single document
• The supplier is not VAT-registered — if the supplier is not a VAT payer, VAT is not in play at all
• Supply for the customer's private use — reverse charge only applies to the customer's economic activities

Frequently Asked Questions

Do I, as a self-employed tradesperson (OSVČ), need to know about reverse charge?

If you are VAT-registered and carry out construction or assembly work, then yes — it is your legal obligation. If you are not VAT-registered, reverse charge doesn't affect you and you invoice without VAT as usual.

What if I'm not sure whether my work counts as construction?

In cases of doubt, consult the CZ-CPA classification. If you're still unsure, contact the Czech Statistical Office to request a formal classification ruling, or consult your tax adviser. The Financial Administration has also published guidance materials on this topic.

How does it work with subcontractors?

The same way. If a main contractor subcontracts work to a subcontractor, and both are VAT-registered, the subcontractor invoices the main contractor under reverse charge. The main contractor then invoices the client under reverse charge as well (provided the client is VAT-registered).

Does reverse charge on construction work still apply in 2026?

Yes. The temporary regime for construction and assembly work (§ 92e) has been extended until the end of 2026 under EU Council authorisation. Any further extension will be decided during the course of 2026.

What happens if I invoice incorrectly?

If you mistakenly invoice with VAT instead of using reverse charge, the customer has no right to deduct that VAT and you are obliged to remit it. Conversely, if you mistakenly invoice without VAT (as reverse charge) when you should have used the standard regime, the customer will have incorrectly declared VAT, which can cause problems for both parties upon audit. In either case, a corrective tax document must be issued.

Can the supplier and customer agree to opt out of reverse charge?

No. The reverse charge regime is a statutory obligation, not an option. If a supply meets the conditions for reverse charge, it must be applied. Any agreement between the parties to do otherwise has no legal effect.

Summary Table

Conclusion: Reverse Charge Isn't Complicated Once You Know the Rules

The reverse charge VAT mechanism may seem complex at first, but in practice it's a fairly straightforward system. The key is knowing when to apply it, issuing invoices correctly, and keeping careful records in your VAT control statement and return.

Key principles:

1. Always verify the customer's VAT registration status
2. Correctly classify the supply (CZ-CPA for construction, relevant annexes for commodities)
3. Never show a VAT amount on the invoice — include only the tax base and rate
4. Always include the mandatory reverse charge statement
5. Complete the VAT control statement correctly with the appropriate supply type code
6. As the customer, don't forget to declare the VAT and simultaneously claim the deduction
