Structures the tax questions a growing business faces — corporate income, sales and use, payroll, nexus, and the obligations created by hiring or selling somewhere new. Use this to work out what a new state or country obligates you to, prepare for a tax filing or audit, understand sales tax on your product, or check what a remote hire or new market triggers.
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
# Tax Tax obligations are created by facts — where you sell, where people work, what you sell — not by decisions anyone consciously makes. The characteristic failure is discovering an obligation years after it began, with penalties and interest attached. **This structures the question and tells you what to ask. Tax is technical, jurisdiction-specific, and changes frequently. Positions on anything material belong with a qualified tax adviser or CPA, not a checklist.** ## Nexus: the thing that creates obligations quietly Nexus is the connection that gives a jurisdiction the right to tax you. It is established by activities most companies do not think of as tax events: - **An employee working somewhere.** One remote hire in a new state commonly creates payroll registration, income tax withholding, and often corporate income tax nexus. - **Economic activity without physical presence.** Since *Wayfair*, US states set sales-tax nexus on revenue or transaction thresholds — a few hundred thousand dollars, or a couple of hundred transactions, with the numbers differing by state. - **Inventory held somewhere**, including in a third-party fulfillment warehouse you never visit. …

How to install
mdr add cbrock84/headcount/tax@sha256:cf6d604e114e0adeThe line at the top of this page pins the label git:20260916.0e7cd01, 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.
