Moving to Hungary: the first six things to sort out

The order matters more than most guides admit. Several of these steps depend on the previous one, and getting them out of sequence can cost weeks.

1. Address card (lakcímkártya). Registered at the district government office once you have a place to live and a landlord's declaration. Almost everything else depends on this.
2. Tax identification number (adóazonosító jel). Issued by the tax authority, free of charge. Your employer cannot legally pay you without it.
3. Social security number (TAJ). Gives access to healthcare. An employee normally receives it through their employer's registration; the self-employed apply themselves.
4. Ügyfélkapu / DÁP. The government's electronic identification. Without it you cannot see your tax return draft, your pension record, or most official correspondence.
5. Bank account. Hungarian employers can pay to a foreign account, but tax refunds are considerably simpler with a domestic one.
6. Determine your tax residency. Do this before your first payslip, not at the end of the year — it changes what is taxable and where.

The 183-day rule: what it does and does not mean

This is the single most misunderstood rule among newcomers. The 183 days do not decide whether you are a Hungarian tax resident. They decide something narrower: whether the country where you physically work may tax your employment income.

Under the standard treaty article, your employment income stays taxable only in your country of residence if all three of these hold:

• you spend fewer than 183 days in the other country within the relevant twelve-month period;
• your pay is not borne by an employer resident in that other country;
• your pay is not borne by a permanent establishment there.

Fail any one of them and the work country may tax the income. A common trap: a foreign employee working in Hungary for a Hungarian subsidiary is taxable here from day one, because the second condition fails — regardless of the day count.

Residency itself is decided separately, by the tie-breaker order: permanent home, then centre of vital interests, then habitual abode, then nationality. Someone can easily be resident in one country while their salary is taxed in another.

Which treaty method applies to your country?

Hungary has treaties with roughly eighty countries, and they do not all work the same way. Two mechanisms exist, and which one applies changes your outcome substantially.

Exemption. Income taxed abroad is exempt in Hungary. Most European treaties — including those with Germany and Austria — use this for employment income. Because Hungary applies a single 15 percent rate, there is no progression effect either, so in practice no Hungarian tax arises. You must still report the income.

Credit. Hungary taxes the income too, but the tax paid abroad is deductible. You pay the difference here. This appears in a minority of treaties.

No treaty at all. This became relevant for Americans in 2024, when the Hungary–United States treaty ceased to have effect. Without a treaty the domestic rule applies: 90 percent of the foreign tax paid can be credited, but the Hungarian tax cannot fall below 5 percent of the income. Anyone with US-source income should have this reviewed — the position changed materially and many people have not noticed.

Social security and the A1 certificate

Tax and social security are decided by different rules, and confusing them is expensive. Within the EU the basic principle is that you are insured in the country where you actually work — not where your employer is registered, and not where you pay income tax.

The exception is a posting. If your employer sends you to Hungary temporarily, an A1 certificate issued by your home country's institution keeps you in that country's social security system. Without it, Hungarian contributions become payable — 18.5 percent from the employee and 13 percent from the employer.

Two practical points. The A1 must be obtained before the posting begins; retrospective issue is possible but slow and not guaranteed. And an A1 says nothing about income tax — you can hold a valid A1 and still owe Hungarian income tax on the same work.

Common situations, and what actually happens

Deadlines worth putting in your calendar

• 20 May — annual return deadline, and the payment date for any tax due.
• Quarterly, by the 12th — tax advance if you have no Hungarian payer (January, April, July, October).
• Five years — the limitation period. Missed allowances can be reclaimed by self-revision this far back, and the authority can audit this far back too.
• 30 days — payment deadline once a duty assessment arrives, which can be months after a property purchase.

What this site can and cannot do for you

These calculators apply the 2026 Hungarian rules and are useful for working out what a given salary, fee or transaction produces. They are built and maintained by one person, and they are not tax advice.

Cross-border situations in particular turn on facts a calculator cannot see: which treaty applies, where your centre of vital interests lies, whether an A1 exists, how your employment is structured. Where real money is at stake, the calculators are a good way to arrive at your accountant's office already knowing which questions to ask — not a substitute for asking them.
