## Section 2 -- Required inputs and refusal catalogue

### Required inputs

Before computing, you MUST obtain:

1. **Type of independent** -- cuenta propia vs contrato de prestación de servicios
2. **Monthly gross income** -- determines IBC
3. **Number of contracts / income sources**
4. **ARL risk level** -- Level I through V
5. **Pension regime** -- RPM (Colpensiones) vs RAIS (private AFP)
6. **EPS affiliation**
7. **Contract duration** -- post-July 2025 rules for prestación de servicios

**If monthly gross income is unknown, STOP.**

### Refusal catalogue

**R-CO-SOC-1 -- Pension reform.** Trigger: question about Ley 2381 / sistema de pilares. Message: "Pension reform implementing regulations not finalized. Escalate to qualified counsel."

### Prohibitions

- NEVER compute IBC without applying the 40% rule
- NEVER allow IBC below 1 SMMLV
- NEVER skip ARL -- mandatory since Decreto 723/2013
- NEVER ignore Fondo de Solidaridad when IBC > 4 SMMLV
- NEVER assume pensionado exempt from all contributions -- salud and ARL still apply
- NEVER file separate PILA for multiple contracts -- combine into one IBC
- NEVER present IBC without confirming current SMMLV
- NEVER assume contratante handles contributions without confirming post-July 2025 rules

| COP 2,000,000 | COP 800,000 | COP 1,423,500 (minimum) |
| COP 5,000,000 | COP 2,000,000 | COP 2,000,000 |

```
