| 40 | ## Section 2 -- Required inputs and refusal catalogue |
| 41 | |
| 42 | ### Required inputs |
| 43 | |
| 44 | Before computing, you MUST obtain: |
| 45 | |
| 46 | 1. **Business registration** -- registered działalność gospodarcza? |
| 47 | 2. **Months in business** -- first 6 months (Ulga na start)? First 24 months after Ulga (Preferencyjne)? |
| 48 | 3. **Prior-year revenue** -- determines Mały ZUS Plus eligibility |
| 49 | 4. **Health insurance basis** -- which tax form (PIT-36, PIT-36L, PIT-28)? |
| 50 | 5. **Voluntary sickness insurance?** -- chorobowe is optional |
| 51 | 6. **Any concurrent employment?** -- may exempt from certain ZUS obligations |
| 52 | |
| 53 | **If months in business is unknown, STOP. Different regimes apply based on tenure.** |
| 54 | |
| 55 | ### Refusal catalogue |
| 56 | |
| 57 | **R-PL-ZUS-1 -- Cross-border EU worker.** Trigger: client works in Poland and another EU state. Message: "EU Regulation 883/2004 applies. A1 certificate required. Escalate to reviewer." |
| 58 | |
| 59 | ### Prohibitions |
| 60 | |
| 61 | - NEVER compute health insurance without knowing the tax form -- rates differ between PIT-36, PIT-36L, and PIT-28 |
| 62 | - NEVER apply Ulga na start or Preferencyjne to clients providing services to their former employer |
| 63 | - NEVER forget that sickness insurance (chorobowe) is VOLUNTARY for self-employed |
| 64 | - NEVER ignore the 36/60 month limit on Mały ZUS Plus usage |
| 65 | - NEVER state health contributions are fully tax-deductible -- deductibility depends on tax form |
| 66 | - NEVER apply Fundusz Pracy when the contribution base is below the minimum wage |
| 67 | - NEVER double social contributions for clients with multiple businesses |
| 68 | - NEVER present Ulga na start as risk-free -- the client has NO social coverage during this period |

| 118 | ### Step 5.1 -- Determine tier |
| 119 | |
| 120 | ``` |
| 121 | IF months_in_business <= 6 AND ulga_na_start_used: |
| 122 | tier = "ulga_na_start" |
| 123 | ELIF months_in_business <= 30 AND preferencyjne_eligible: |
| 124 | tier = "preferencyjne" |
| 125 | ELIF prior_year_revenue < 120,000 AND maly_zus_eligible: |
| 126 | tier = "maly_zus_plus" |
| 127 | ELSE: |
| 128 | tier = "standard" |

| 135 | retirement = social_base x 19.52% |
| 136 | disability = social_base x 8.00% |
| 137 | sickness = social_base x 2.45% (if opted in) |
| 138 | accident = social_base x 1.67% |
| 139 | fundusz_pracy = social_base x 2.45% (only if base >= minimum wage) |
| 140 | total_social = retirement + disability + sickness + accident + fundusz_pracy |
| 141 | ``` |
| 142 | |

| 144 | |
| 145 | ``` |

| 148 | health = health_base x 9% |
| 149 | ELIF tax_form == "PIT-36L": |
| 150 | health_base = max(actual_monthly_income, 75% of min_wage) |
| 151 | health = health_base x 4.9% |
| 152 | ELIF tax_form == "PIT-28": |
| 153 | health = ryczałt_bracket_amount |
| 154 | ``` |
| 155 | |
| 156 | ### Step 5.4 -- Mały ZUS Plus base |
| 157 | |
| 158 | ``` |
| 159 | annual_income = prior_year_income (profit, not revenue) |
| 160 | daily_base = annual_income x 30 / number_of_days_of_activity |
| 161 | monthly_base = daily_base x 30 |
| 162 | monthly_base = clamp(30% of min_wage, monthly_base, 60% of avg_wage) |
