Invoicing in Croatia: Key Legal Requirements Every Business Should Know

Whether you run a small trade or a limited company, issuing correct invoices is a fundamental part of doing business in Croatia. Getting it right keeps your accounts in order, ensures you can reclaim VAT where applicable, and helps you avoid unnecessary penalties. Here is a practical guide to the key legal requirements.

Mandatory invoice elements

Under Croatian tax law, every invoice must contain certain information to be valid for tax purposes. These elements include:

• The word 'Invoice' (Račun) and a unique sequential number
• The date of issue and the date of supply of goods or services (if different)
• The seller's name, address, and VAT identification number (if applicable)
• The buyer's name and address, and VAT number if the buyer is liable for VAT
• A clear description of the goods or services supplied, including quantity and unit price
• The total amount due, broken down by VAT rate (if applicable)
• The applicable VAT rate and the VAT amount charged
• Any discounts or rebates, if not included in the unit price

For invoices below a certain threshold, some simplifications may apply, but it is generally best practice to include all the details above.

VAT on invoices

Croatia applies several VAT rates. The standard rate is 25%, with reduced rates of 13% and 5% for certain goods and services, such as some foodstuffs, medicines, books, and accommodation. When you issue an invoice for a taxable supply, you must clearly state the VAT rate and the amount of VAT charged. If your business is not registered for VAT, you must not charge VAT and should state that the supply is exempt.

For cross-border transactions within the EU, different rules apply depending on whether the customer is a business or a consumer. In business-to-business supplies, the reverse charge mechanism often shifts the VAT liability to the buyer. Invoices for such supplies should include a reference to the reverse charge.

Payment deadlines and retention

There is no universal statutory payment deadline for invoices, but Croatian commercial practice often uses 15, 30, or 60 days. The law does provide rules on late payment interest for commercial transactions, so it is wise to state your payment terms clearly on the invoice.

You are required to keep copies of all issued invoices for at least 11 years. This is important for tax audits and for proving your income and VAT position.

E-invoicing

Croatia has been moving towards electronic invoicing, particularly for public procurement. Since 2019, all suppliers to public sector bodies must issue e-invoices in a structured format. For private businesses, e-invoicing is not yet mandatory but is becoming increasingly common. If you choose to use e-invoices, they must meet the same legal requirements as paper invoices and be stored securely.

Penalties for non-compliance

Issuing invoices that do not meet the legal standards can result in fines. The exact amount depends on the nature of the violation, but it is best to ensure your invoices are always complete and accurate. Keeping proper invoicing records also supports your own financial management and helps you avoid disputes with customers.

By following these basic rules, you can keep your Croatian business compliant and your cash flow healthy. When in doubt, consult a local accountant or tax advisor who is familiar with the current regulations.
