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.

# Estimated Tax Payments Calculate and schedule quarterly estimated tax payments to avoid underpayment penalties. Essential for self-employed individuals, freelancers, and small business owners who don't have taxes withheld from a paycheck. ## Why you need to pay quarterly Employees have taxes withheld every paycheck. Self-employed people don't. The IRS expects to receive tax payments throughout the year, not one lump sum in April.

How to install
mdr add receiptor-ai/bookkeeping-skills/estimated-taxes@sha256:32edd14270517609The line at the top of this page pins the label git:20260324.5e6a98c, 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.
