NomiCheck bronze

Colombian payroll legal parameters, by date

Returns the Colombian statutory payroll and tax parameters in force on ANY given date - minimum wage, transport allowance, UVT, night/Sunday premiums, the ordinary-hour divisor, social security rates, garnishment and withholding caps - each with its unit, its legal source and the decree or resolution that set it. Pass `?fecha=YYYY-MM-DD` to resolve against the dated history seeded from 2020; omit it for today. The numbers themselves are public: what is not public is the maintained, dated, sourced history, signed with Ed25519 and carrying the sha256 of the catalog that produced it - so an auditor can cite what was in force on the day of a retroactive settlement without trusting the party that computed it. Keys with no value on the requested date are named in `noVigentes` with the reason, never silently dropped.

• What was the Colombian minimum wage and transport allowance on 2024-03-15?
• Give me the UVT and withholding caps in force in June 2021
• I need signed proof of the ordinary-hour divisor that applied in 2023

Colombian withholding tax (retencion en la fuente)

Computes monthly withholding tax per person from numeric parameters only. Input is fully anonymous: no name, no national ID. Returns the taxable base in COP and UVT, the withholding amount, and the legal reference for each line.

• Compute withholding for a 8,000,000 COP monthly salary, non-declarant
• Batch of 50 employees with dependents and prepaid medicine deductions

Payslip pre-check (free, no payment required)

Free triage of the same payslips: returns HOW MANY have discrepancies and the estimated net impact in COP, with the rule-catalog hash it was measured against — but never which line or which statute, which is the paid report. Same deterministic engine as the paid endpoint: if the pre-check says N, the report finds N. Free by design, not by promotion: a verifier that charges according to what it finds has the wrong incentive. If your payslip is clean you find out for free and never pay.

• Is there anything wrong with my payslip? (free, no payment)
• Triage 300 payslips and tell me how many are worth a paid report

Payslip compliance verification

Independently recalculates the legal lines of a payslip (base salary, transport allowance, health, pension, solidarity fund) and compares them against what the payslip declares. Returns a per-line verdict and the estimated net impact on the worker. Extralegal items are flagged as non-verifiable rather than guessed. Try `payslip-precheck` first: it is free, needs no payment or signup, and tells you whether this paid report would find anything.

• Does this payslip comply with 2026 Colombian labor law?
• Verify 200 payslips and flag underpayments

Full payroll settlement

Complete payroll run for a company: accruals, deductions, overtime and night/holiday surcharges, social security contributions. Each line carries its legal reference and the batch carries the rule-catalog hash.

• Settle July 2026 payroll for 120 employees

Colombian final settlement (liquidacion de contrato)

Computes what an employer owes a worker when a contract ends: accrued severance (cesantias), its statutory 12% interest, the pro-rata statutory bonus (prima) and unused vacation, plus dismissal indemnity when requested. Each concept is settled from its OWN cut-off date, because they are not paid on the same cycle - settling them all from the hire date is the classic spreadsheet error and pays twice for what was already paid. The caller declares the payment history (cortePrima, corteCesantias, diasVacacionesTomados); anything not declared is assumed to be the simple case and the assumption is returned explicitly in `supuestos`, never silently. Transport allowance is sent as a right (boolean), not an amount: the server resolves the figure that was in force on the termination date from the signed rule catalog, so retroactive settlements use period-correct values. Returns one line per concept with its legal citation.

• Settle a contract that ran from March 2024 to July 2026, prima already paid through June
• Final settlement for 40 employees laid off in the same month, with indemnity
• What is owed to someone dismissed during the probation period?

Non-custodial USDC contractor payout batch

Converts COP amounts to USDC using the official TRM rate from datos.gov.co, frozen with a sha256 hash and an expiry window so the rate is auditable after the fact. Produces EIP-681 payment links and a Gnosis Safe batch JSON. The payer signs from their own wallet; this service never holds or moves funds.

• Pay 30 Colombian contractors in USDC on Base with a frozen TRM rate

NomiCheck — Colombian payroll law, dated and verifiable

Colombian payroll law as a dated, verifiable catalog, with the engine that applies it. Any statutory parameter resolvable on any date since 2020 — each with the norm that set it — plus deterministic calculators for payroll, withholding tax, payslip verification and final settlement. Every result cites its legal basis, carries the sha256 of the catalog that produced it and is signed with Ed25519, so a third party can verify it without trusting the issuer and without calling back to the server.

Sobre verifier — check a signed agent output against its own claims

Zero-dependency web verifier for 'el sobre': an open format where a signed output carries its rule-catalog hash and the date the rules were checked. Verifies the Ed25519 signature in the browser via WebCrypto. Three verdicts, not two — verifiable, invalid, or signed-without-provenance, because a valid signature proves who said it, not that it is right.
