165## Section 4 -- Worked examples
166 
167### Example 1 -- Átalányadó IT consultant
168 
169**Input:** Revenue HUF 18,000,000, 40% cost ratio, single.
170**Computation:** Deemed costs = HUF 7,200,000. Taxable = HUF 10,800,000. SZJA = 15% = HUF 1,620,000. SZOCHO = 13% = HUF 1,404,000. TB = 18.5% = HUF 1,998,000.
171 
172### Example 2 -- KATA disqualification
173 
174**Input:** KATA freelancer invoices HUF 500,000 to a Kft. in March.
175**Result:** Immediate KATA loss for entire year. Must re-file under standard or átalányadó. All income re-taxed.
176 
177### Example 3 -- Standard regime, two-layer
178 
179**Input:** Revenue HUF 30,000,000, expenses HUF 12,000,000, withdraws HUF 10,000,000.
180**Computation:** Profit = HUF 18,000,000. Vállalkozói adó = 9% = HUF 1,620,000. SZJA on withdrawal = 15% x HUF 10,000,000 = HUF 1,500,000. SZOCHO on withdrawal = HUF 1,300,000. TB = HUF 1,850,000.
181 
182### Example 4 -- Minimum contribution trap
183 
184**Input:** Revenue HUF 1,500,000/year.
185**Computation:** Monthly income HUF 125,000. Minimum base HUF 290,800. SZOCHO = HUF 37,804/mo. TB = HUF 53,798/mo. Annual contributions = HUF 1,099,224. This is 73% of revenue -- flag as potentially unviable.
