Outsourced bookkeeping for Denver companies, including the per-employee occupational privilege tax that has nothing to do with income.
At a glance
Colorado's state corporate tax is refreshingly simple: a flat rate rather than brackets, which makes reserving straightforward. Denver adds something less obvious.
The Occupational Privilege Tax is charged per employee per month as a flat dollar amount, split into an employee portion withheld from pay and an employer portion the company owes on top. It scales with headcount, not with revenue or profit.
Because it is a flat per-head charge rather than a percentage, it does not fall out of a standard payroll calculation the way income tax withholding does. It has to be configured deliberately, and it is one of the more common things we find missing when we take over a Denver company's books.
Hiring in Denver adds a small, predictable, recurring liability per person. It is never large enough to change a hiring decision, and it is exactly the kind of thing that quietly accrues unfiled if nobody set it up.
Daily categorisation, a monthly close with a named accountant, payroll configured so the OPT is actually withheld and remitted, and burn and runway kept current as headcount grows. Delaware C-corps get the franchise tax alongside.
