Frequently Asked Questions

How often is VAT filed in Croatia?
This calendar shows a monthly VAT filing — 12 of them across the 2026 calendar. Each one falls on the 20th of the month. Filing frequency depends on the turnover band and the scheme a business is registered under, so a smaller business may report less often than the monthly cycle listed here. Confirm your own frequency with Porezna uprava.
When is the personal income tax return due in Croatia?
Apr 30, 2026 (Personal Income Tax Return — Filing Deadline). Extensions and agent-filed deadlines can differ; the dates above are the ones shown on this calendar.
How often are payroll and social security contributions paid in Croatia?
The calendar lists 1 social security deadline for the 2026 period — see the months listed below. Employer obligations depend on headcount and payroll size.
What does this Croatia tax calendar cover?
14 filing and payment deadlines for 2026, grouped by month: vat, personal income tax and social security. Each entry names the form where one applies and flags public holidays that fall near a deadline. The authority behind these dates is Porezna uprava.
Is this calendar official Porezna uprava guidance?
No. It is a plain-English summary built to help you plan, and it is not tax advice. Dates can change, and your own obligations depend on your registration, turnover and scheme. Always confirm against Porezna uprava before you rely on a date, and speak to a qualified adviser about your own situation.
Do EU-wide VAT rules change these Croatia dates?
The EU VAT Directive sets a common framework, but each member state keeps its own filing calendar, thresholds and rates — which is why Croatia has its own page here rather than a shared EU one. If you sell across borders, the One-Stop Shop lets you declare VAT centrally instead of registering in each country.

Before you file or pay

How to verify a Croatia tax deadline

1. Match the obligation. Check the tax type, period, registration and filing method. A VAT, payroll or income-tax date may not apply to every taxpayer.
2. Check the live notice. Public holidays, agent arrangements, extensions and account-specific instructions can change the operational due date.
3. Keep proof. Save the submission receipt and payment confirmation. Filing and paying can be separate actions with separate cut-off times.

Why this matters: missed dates can lead to late filing charges, interest, loss of a relief or an avoidable compliance review. This page is a planning aid, not a legal determination. It was last content-reviewed on 2026-08-14; verify the live rule with Porezna uprava before acting.
