Required inputs before computing
Before computing, you MUST obtain: 1. Self-employment type -- egyéni vállalkozó (sole proprietor) vs KATA taxpayer vs freelancer? 2. Monthly income / chosen contribution base 3. Is the client full-time (főállású) or part-time (mellékállású)? -- minimum base rules differ 4. Does the client opt for itemized or flat-rate taxation? 5. Any concurrent employment? -- affects minimum base. If self-employment type is unknown, STOP.
R-HU-SOC-1 -- Cross-border worker
Trigger: client works in Hungary and another EU state. Message: "EU Regulation 883/2004 requires A1 certificate determination. Escalate."
Prohibitions list
NEVER compute without knowing főállású vs mellékállású -- minimum base rules differ completely. NEVER apply a cap on TB or SZOCHO -- there is no upper ceiling. NEVER confuse SZOCHO (13%, tax) with TB járulék (18.5%, insurance contribution). NEVER advise a KATA taxpayer to invoice companies -- only natural persons since September 2022. NEVER forget the minimum base is minimum wage (HUF 266,800) or guaranteed minimum (HUF 326,000). NEVER state that mellékállású has a minimum base -- it does not. NEVER present KATA as available for B2B freelancers. NEVER ignore pro-rating for partial months.
