You have people on both sides of a border. Cousins in Split who ask you which insurance to take, colleagues in Munich or Dublin who ask which bank works when they move back, a group chat that treats you as the person who knows how things are done in Croatia. That is a referral network, whether or not you have ever called it one. Turning it into income is less about audience size than about three unglamorous decisions taken before the first euro moves: how you declare the money, which account receives it, and what the programme actually promised in writing. Get those wrong and a commission either never arrives or costs more than it pays. This guide works through them in the order you will meet them, with the Croatian rules that apply and the ones that do not exist at all. Because commissions arrive late and in uneven lumps, some people bridge the wait with I am Beezy, an app that pays a small amount for each video, article or advert consulted, sent to the payment method they already use.
What referral income really is, and why a diaspora network suits it
Commission, finder's fee, and the difference that matters
Affiliate income pays you a share when someone you sent completes an action: opens an account, buys a policy, books a stay. A finder's fee pays you for the introduction itself, whether or not the deal closes. The two look similar on a landing page and behave completely differently in your bank statement. Affiliate commissions are small, frequent and dependent on someone else's conversion rate. Finder's fees are rarer, larger and dependent on a relationship you can name. Before you sign anything, write down which of the two you are being offered, because it changes how long you wait to be paid. A programme that will not answer that question clearly is telling you something.
Two markets, one contact list
Croatia is a small, older country: the national statistics office puts the population at 3,866,233 in the middle of 2024, with an average age of 44.5 years. A domestic-only referral audience is therefore limited by arithmetic, not by your effort. A diaspora list is different because it spans two price levels and two sets of habits at once. The people who move back ask about banks, insurers, energy suppliers and mobile plans in a compressed window of a few weeks, which is exactly when a referral is useful rather than annoying. That timing, not volume, is the asset you are working with.
Where the seasons put your audience
The Croatian calendar splits the country in two. In 2025 the national statistics office counted 26,711,796 overnight stays in August against 650,315 in January. Anything you promote around travel, short-term rental, insurance or car rental has a demand curve that follows that shape. Anything you promote around banking, tax or employment does not. Knowing which of the two your programme belongs to tells you when to send an email and when to leave people alone.
Which declaration route should you take before the first payout?
Drugi dohodak: the payer does the paperwork
If you do not open a business, occasional income falls into the category the tax administration calls drugi dohodak. Its defining feature is who handles the declaration: the Porezna uprava states that the person or company paying you is the one obliged to calculate, withhold and pay the tax and contributions. Pension contribution is 10% of the gross amount for someone insured in the first pillar only, and 7.5% for someone also enrolled in the individual capitalised second pillar. Income tax then applies to the amount received after that contribution. The exact percentage is not national, and there is no single Croatian rate to quote — see below.
Paušalni obrt: a fixed monthly cost whatever you earn
The standard route for a declared small activity is the paušalni obrt, the flat-rate craft business. Its ceiling is 60,000.00 euros of receipts in the previous year, and the taxable base is a flat figure per bracket rather than a percentage: 1,695 euros of base under 11,300 euros of receipts, rising through 2,295, 2,985, 4,590, 6,000 and 7,500 to 9,000 euros for receipts between 50,000 and 60,000 euros. The part people miss is the contributions. They are calculated on a fixed monthly base of 797.20 euros no matter which bracket you land in. That is 119.58 euros a month for the first pension pillar at 15%, 39.86 euros for the second at 5% and 131.54 euros for health cover at 16.5% — close to 291 euros every month, earned or not.
The 60,000 euro line that moves two things at once
The same 60,000 euros is also the threshold above which registration for VAT becomes compulsory, at a standard rate of 25%. Crossing it therefore changes two regimes in a single step, which is why the figure is worth writing on a sticky note rather than remembering vaguely. On timing: a new craft business has eight days from starting to opt for the flat-rate regime, an existing one must request the switch before 31 December for the following year, the annual return is due by 15 January, and contributions are payable by the fifteenth of the following month.
| Question | Drugi dohodak | Paušalni obrt |
|---|---|---|
| Who declares | The payer withholds and pays | You, with an annual return by 15 January |
| Fixed monthly cost | None | Contributions on a base of 797.20 euros |
| Pension contribution | 10%, or 7.5% with second pillar | 15% first pillar plus 5% second pillar |
| Ceiling | Not a flat-rate ceiling | 60,000.00 euros of receipts |
| Suits | Irregular, small amounts | Steady receipts that cover the fixed cost |
One caution that matters more than any calculation: income tax rates in Croatia are set by each municipality and town, by a decision published before the end of November for the following year. There are two rates, a lower one applying up to 60,000 euros a year and a higher one above that, but the percentages themselves are local. Anyone quoting you a single national Croatian income tax rate is guessing.
Getting paid: the account decides, not the app
A Croatian IBAN or a passported one
The Croatian central bank keeps a public register of licensed credit institutions, and its update of 18 May 2026 lists 19 banks. Those banks issue an IBAN beginning with HR. Revolut, N26 and Wise are not on that register: they operate in Croatia under freedom of services with an IBAN issued elsewhere. Inside the single euro payments area that is perfectly legal, but some payers and administrations still prefer a domestic account. If a programme is your main income line, open the account that no counterparty can refuse rather than the one that opened fastest.
KEKS Pay and Aircash, and what they are for
Two Croatian applications matter for moving small amounts between people. KEKS Pay is published by Erste but usable without an Erste account, handles transfers and QR payments, and its publisher claims more than 500,000 users. Aircash is a Croatian electronic money institution offering a wallet, a prepaid Mastercard and cash top-ups at partners, and claims more than a million and a half users. Neither is a universal interbank scheme, and neither replaces a bank account for receiving commissions. Treat them as the last leg, not the rail.
No currency conversion to worry about
Croatia is in the euro area, so a euro transfer to an HR IBAN involves no conversion at all. This is worth stating plainly because so much affiliate advice is written for countries outside the euro, where comparing exchange rates is a genuine part of the job. Here it is not. The comparison that stays useful concerns fees on incoming transfers from outside the single euro payments area, and the delay before the money is available — ask your bank for the full price list rather than the headline.
How do you separate a serious programme from a dressed-up scam?
The questions to ask before signing
Ask who the contracting entity is and in which country it is registered. Ask what triggers the commission and how long the attribution window lasts. Ask when payment is released, what the minimum payout is, and what happens to earned amounts if you stop promoting. Ask whether the programme can change the rate retroactively. A programme that answers all five questions in writing is behaving normally, and one that answers none is not a programme but a pitch. None of this requires legal expertise, only the patience to send the email before rather than after.
The shapes that should stop you
Two structures deserve immediate suspicion. The first is any arrangement where you pay to join, buy a starter pack, or must recruit other participants to unlock your own earnings — that is recruitment income wearing an affiliate badge. The second is the guaranteed return: no legitimate programme knows in advance what your audience will do. Add a third, quieter warning sign: a programme that pays only in credit, points or vouchers redeemable on its own site, which converts your work into a purchase obligation. Regulated financial products carry their own rule, and the supervisor is not always who you expect — banks answer to the Croatian National Bank, while insurance, capital markets and pension funds fall under HANFA.
| Signal | Serious programme | Walk away |
|---|---|---|
| Joining | Free, with a named legal entity | Entry fee or compulsory pack |
| Earnings | Paid on a defined action | Paid for recruiting others |
| Terms | Written, dated, downloadable | Explained only in a chat message |
| Payment | Bank transfer on a stated schedule | Internal credit or vouchers only |
Bridging the wait between commissions with I am Beezy
What the application actually pays for
I am Beezy is an application where you consult content — videos, articles, advertising — and each consultation generates a payment sent to your local payment method. Across the platform the realistic range is between 5 and 15 euros a day. It is not a replacement for a referral programme and it does not scale with a contact list; it is a small, regular amount that does not depend on anyone else converting.
Where it fits in a referral plan
The hardest part of building referral income is the first quarter, when the work is done and nothing has yet been paid. Attribution windows, minimum payout thresholds and monthly payment runs can push your first real transfer several months out. A small daily amount arriving in that window changes your behaviour: you keep sending the useful recommendations instead of abandoning the whole idea in week six. That is the only role it needs to play.
The first three months, step by step
Weeks one to four
Pick one sector you can genuinely advise on and one programme inside it. Read the terms, ask the five questions, and keep the answers. Decide your declaration route before you promote anything, using the fixed monthly cost of a flat-rate craft business as the deciding number: if your realistic first-year receipts do not comfortably exceed roughly 291 euros a month of contributions plus the tax due on the flat base, the occasional-income route is the honest starting point.
Weeks five to twelve
Send recommendations only where they are asked for, and log every one with a date. At the end of the quarter compare your log against the programme's dashboard: the gap between the two tells you whether the attribution actually works. If the gap is large and unexplained, change programme rather than change effort. Keep every payout confirmation in a single folder from day one, because reconstructing a year of small transfers in January is the part everyone underestimates. When the arithmetic starts to hold together, revisit the declaration decision — the ceiling and the VAT threshold sit at the same 60,000 euros, and it is far easier to plan for that line than to discover it. If you want a small daily amount arriving while the referral side matures, I am Beezy is one way to keep the months in between from feeling empty.
