Spremni za eRačunRequest service
For flat-rate sole traders (paušalni obrt), freelancers and small companies in Croatia outside VAT

Croatian eRačun ready before 1 January 2027, without the guesswork

Croatian income-tax and profit-tax payers who are not registered for VAT, including flat-rate sole traders, must issue and fiscalise eRačun e-invoices to other businesses from 1 January 2027, and have had to receive them since 1 January 2026. Spremni za eRačun sets up the Tax Administration's free MIKROeRAČUN app or your current software in one video call, checks receiving and issues your first eRačun with you. The first step, a check of what applies to you, costs €5 and is credited in full against setup if you order within 30 days.

Why now

From 1 January 2027 a PDF sent by email is no longer enough

Croatia's Fiscalisation Act (Zakon o fiskalizaciji, NN 89/2025) introduced Fiskalizacija 2.0. VAT-registered businesses have issued and fiscalised eRačun since 1 January 2026. Income-tax payers from self-employment and profit-tax payers who are not on the VAT register have had to receive eRačun since 1 January 2026, and must also issue and fiscalise them from 1 January 2027. The law does not name flat-rate sole traders (paušalisti), but they pay income tax from self-employment, so the obligation covers them too.

It applies to invoices to other businesses in Croatia. Invoices to consumers are not eRačun; they are fiscalised as ordinary invoices, which since 1 January 2026 applies whatever the payment method, bank transfers included. The Tax Administration offers a free app, MIKROeRAČUN, which has been able to issue eRačun since 20 October 2026, and the paid tools we checked start at €8 a month excluding VAT.

None of the steps is hard, but they are scattered across ePorezna, the NIAS login, MIKROeRAČUN's terms of use, FiskAplikacija and, if you use other software, authorising an information intermediary, and the official guidance is in Croatian. Spremni za eRačun goes through them with you in one call and checks everything works before January.

How it works

How it works

  1. 1

    A short questionnaire

    Your legal form, whether you are VAT-registered, what you invoice with today, how many invoices you send to businesses each month and who keeps your books. Five minutes.

  2. 2

    Written check

    Within one business day we send a written answer: what applies to you, from when, and which route to take, MIKROeRAČUN, your current software or something else. If the free route without us is enough, we say so.

  3. 3

    Video call with screen share

    You log in to ePorezna through NIAS; we guide each step: MIKROeRAČUN or your software, the FiskAplikacija check, receiving, and your first eRačun to one of your business customers. About 45 minutes, in English or Croatian.

  4. 4

    Summary

    One page: what was set up, where incoming eRačun arrive, how to issue the next one and what to do if a customer has no eRačun address.

What it does

Features

Obligation check

A written answer on what applies to you: whether you are VAT-registered, whether you invoice businesses and from when you must issue eRačun. If the free route is enough, we say so.

MIKROeRAČUN set up

ePorezna login through NIAS, terms of use accepted, MIKROeRAČUN confirmed as your information intermediary in FiskAplikacija, and email alerts for new eRačun.

Or your current software

If you already invoice with software that supports eRačun, we connect it and check its information intermediary's authorisation in FiskAplikacija.

Receiving checked

Where incoming eRačun arrive, how to view, accept or reject them and who forwards them to your bookkeeper. This obligation has applied since 1 January 2026.

First eRačun issued with you

We issue your first eRačun to one of your business customers together, so next time you know every step.

Plan for when things go wrong

What to do if a customer has no address for receiving eRačun: the law then allows a paper invoice, with the data sent through e-reporting (eIzvještavanje). We explain how that works in your tool.

One-page summary

What was set up, where invoices arrive, who has access and which dates apply to you. For you and your bookkeeper.

Who it's for

Foreign founders with a Croatian obrt or company

A flat-rate sole trader or small company in Croatia run in English, where the Croatian-only guidance is the main obstacle. We work in English.

Flat-rate sole traders (paušalni obrt)

A few invoices a month to companies and other sole traders, made in Word, Excel or a simple tool. From 1 January 2027 they must be eRačun.

Freelancers and sole traders on income tax outside VAT

Designers, translators, consultants and tradespeople not registered for VAT: the same obligation and the same free route as flat-rate traders.

Small companies outside VAT

A d.o.o. or j.d.o.o. that pays profit tax but is not VAT-registered also issues eRačun from 1 January 2027.

Compared with the alternatives

On your own, with MIKROeRAČUN and the official guides
Free: the Tax Administration provides MIKROeRAČUN, user instructions and leaflets, in Croatian. For many flat-rate traders that is enough with a little time and patience; we shorten it to one call.
Invoicing software (for example Solo or mer)
Solo offers a free plan for up to 3 invoices or quotes a month with sending and receiving eRačun, and its solo plan costs €10 a month including VAT. mer has BASIC MICRO plans from €8 a month excluding VAT plus a €29 activation fee. A good choice if you issue more invoices; if your software already does it, we will tell you straight away.
Your bookkeeping firm
The right choice if your bookkeeper offers the setup and has time before year end. We can also work for the bookkeeping firm, with its clients, on the Bookkeeping firm plan.

Questions

I have a flat-rate sole trade (paušalni obrt). Must I issue eRačun from 2027?

If you are not VAT-registered, yes, for invoices to other businesses in Croatia. The Fiscalisation Act requires income-tax payers from self-employment outside VAT to issue and fiscalise eRačun from 1 January 2027, and they have had to receive them since 1 January 2026.

Do I have to send eRačun to consumers?

No. eRačun is issued to businesses in Croatia, and invoices to consumers are fiscalised as ordinary invoices, since 1 January 2026 whatever the payment method. A transaction with a business paid in cash or by card can be exempt if a fiscalised receipt was issued for it.

Is MIKROeRAČUN really free?

Yes. The Tax Administration describes it as a free app for issuers and recipients who are not VAT-registered and are not public contracting authorities. You log in to ePorezna through NIAS, with no digital certificate.

Why pay you if the app is free?

You do not have to. Our €5 check tells you whether you need help at all, and is credited in full if you then order setup within 30 days. The €9 setup makes sense if you want everything done together in one call, in English, and your first eRačun issued with someone beside you.

What are the fines?

For not issuing or not receiving eRačun, or not fiscalising them, the Fiscalisation Act sets a fine of €3,980 to €39,810 for a sole trader who is a natural person (Article 71).

Do you need my passwords or NIAS login?

No. You always log in to ePorezna yourself, and we guide you over screen share. We do not store your credentials or invoices.

Is this tax advice?

No. Spremni za eRačun is a technical setup service. For tax questions about your business, your bookkeeper, tax adviser or the Tax Administration has the final word.
