Secondary or Main-Occupation Sole Proprietor?

Why does the status matter?

Under the Social Security Benefits Act, 2019. évi CXXII. törvény (Tbj.), every sole proprietor counts as insured through their business activity. But the type of status affects two separate things: how much social security contribution and social contribution tax is due (whether there's a minimum contribution base, or contributions are due only on actual income), and what benefits (like sick pay) can be claimed based on that specific status.

Main-occupation sole proprietor

By default, every sole proprietor counts as main-occupation unless one of the exceptions below applies. For a main-occupation proprietor, the monthly base for social security contribution and social contribution tax is at least the minimum wage, or, if the registered activity requires at least secondary education or a vocational qualification, the guaranteed wage minimum, even if actual income is lower or zero. If income exceeds that floor, contributions are due on the actual income instead. (See the flat-rate tax and VSZJA calculator articles for the exact HUF figures and how the calculation works, and the social contribution tax article for the szocho rules in detail.)

Secondary-occupation sole proprietor

Under Tbj. § 42 (2), a sole proprietor is not subject to the minimum contribution base if, alongside the business activity, they

• also hold employment of at least 36 hours a week, if there's more than one concurrent employment relationship, their weekly hours are added together, or
• are enrolled as a full-time student at a secondary or higher education institution.

In that case, social security contribution and social contribution tax are due only on income actually earned and taxable, with no minimum base: if there's no income in a given month, there's no contribution due either. Importantly, this more favorable rule doesn't mean the business activity stops being its own separate insured relationship: the proprietor is still insured through it, just at a lower contribution base.

Supplementary-activity (own-right pensioner) sole proprietor

The law treats a retired (own-right pensioner) sole proprietor as its own category: the formal term is "kiegészítő tevékenységet folytató személy" (person pursuing a supplementary activity). This covers someone receiving an old-age pension, or who has reached their applicable old-age pension age and receives another pension-type benefit. For them, the business activity is subject to neither social security contribution nor social contribution tax: only SZJA applies to the income.

Benefit eligibility isn't the same question as the tax base

Eligibility for sick pay (and other cash health-insurance benefits) is assessed separately, per insured relationship. That means a secondary-occupation sole proprietor can claim sick pay based on the business activity too, but only if they've actually paid enough contribution, for long enough, in that specific relationship (including the required prior insured period). If a secondary-occupation proprietor goes months without income, and therefore without paying social security contribution on the business activity, that relationship alone doesn't establish sick-pay eligibility: a question entirely separate from whatever eligibility comes from their main employment.

The health-service-contribution risk

If someone has no valid insured relationship at all, no employment, no full-time studies, no pension, and no business activity that actually generates contributions, the law requires paying a fixed, flat monthly health-service contribution (egészségügyi szolgáltatási járulék) to remain entitled to healthcare. In 2026, that's HUF 12,300 a month (HUF 410 a day for a partial month). This most often comes up when someone loses their job, and their secondary, low-income business activity alone isn't enough to maintain continuous insured coverage.

What to do if your status changes

If your insured status changes mid-year, you lose your job, finish full-time studies, or retire, you need to report it to NAV, since a different contribution-base rule applies from that month on. It's worth handling the change promptly: the tax authority checks contribution payments against the status on file, and an unreported change can lead to confusion or an underpayment.
