Calculate gross pay, withholdings, employer contributions and net pay per employee, with total payroll cost and upcoming tax deposit deadlines. Use when the user runs payroll for employees and wants the period's pay, deductions and employer obligations worked out.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Payroll

Track employee wages, deductions, and payroll obligations for "$ARGUMENTS". Calculate gross and net pay, withholdings, and employer contributions.

**Arguments.** `$ARGUMENTS` may contain the project name and optional flags. Take the first token as `<project>` and treat `--skip-checks` as a flag; never include flags in file paths. All paths below use `<project>`. If `--skip-checks` is present, skip the prerequisite check and, **before writing any artifact**, append one line to `.singularskills/log.jsonl`: `{"ts":"<ISO timestamp>","skill":"bookkeeping-payroll","workflow":"bookkeeping","phase":null,"project":"<project>","event":"skipped","artifact":"<artifact file>","note":"<reason or \"none given\">"}`.

**Compute with code.** Perform every calculation (totals, balances, ratios, variances, projections) with a script — Bash, Python or a spreadsheet formula written to a file — and include the computation alongside the result. Never do arithmetic mentally.

## Prerequisites

None — utility skill, run anytime.

## Process

1. **Gather employee information:**
   - List all employees and contractors
   - Record: name, role, pay type (salary, hourly), rate, pay frequency
…

How to install

The exact contents, by fingerprint

mdr add bromso/singularskills/bookkeeping-payroll@sha256:b7bc3886aa9ab703

The line at the top of this page pins the label git:20261029.7f379ee, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
