Section 2 -- Required inputs and refusal catalogue
Required inputs
Before computing, you MUST obtain:
- Type of independent -- cuenta propia vs contrato de prestación de servicios
- Monthly gross income -- determines IBC
- Number of contracts / income sources
- ARL risk level -- Level I through V
- Pension regime -- RPM (Colpensiones) vs RAIS (private AFP)
- EPS affiliation
- 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 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
Section 3 -- IBC calculation
Legislation: Ley 100/1993, Decreto 1273/2018
IBC = monthly_gross_income x 40%
IBC = clamp(1_SMMLV, IBC, 25_SMMLV)

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

Section 5 -- Computation and PILA filing
Computation (Level I)
salud = IBC x 12.5%
pensión = IBC x 16%
ARL = IBC x 0.522%

total = salud + pensión + ARL + solidarity
