Denver, CO Bookkeeping Services — A Home-Rule City That Collects Its Own

Denver collects its own sales tax, and that one fact reshapes your bookkeeping. As a home-rule city, Denver administers its sales and use tax independently of the state — its own registration, its own return, its own rules about what is taxable. Sell into Denver, Aurora, Lakewood and Boulder and you may be dealing with the state plus several cities, each on its own cadence. Denver also levies an Occupational Privilege Tax, a per-employee head tax split between employer and employee for anyone earning above a monthly threshold in the city. Colorado’s flat 4.4% income tax is the easy part of the year.

Running the Numbers in Denver

Denver’s base has shifted hard over the last decade — aerospace and defence, a large and growing tech and software sector, outdoor and consumer brands, cannabis, construction riding sustained population growth, and a dense restaurant and brewery scene. Several of those come with bookkeeping quirks that generic providers handle badly.

Three recur. Multi-city selling, where a brand ships across the Front Range and has sales-tax obligations in several self-collecting cities. Project-based construction, where job costing and retainage need to be tracked properly or margin is invisible until a job closes. And cash-heavy hospitality, where tips, comps and daily deposits have to reconcile to the point-of-sale system rather than being plugged.

Denver Tax Cheat Sheet

City and County of Denver and Colorado Department of Revenue, checked 3 October 2026. Denver sets its own rates, thresholds and rules as a home-rule city and changes them independently — confirm current rates, the Occupational Privilege Tax threshold and your registrations with the city or your CPA.

Denver Collects Its Own — and So Do Its Neighbours

Filing Colorado state sales tax does not discharge your Denver obligation. Denver is self-collecting: separate registration, separate return, and its own view of what is taxable, which does not always match the state’s. Several neighbouring Front Range cities do the same, each independently.

For a business selling across the metro, that means a single month’s sales may need splitting between the state and several cities, each with a different rate and different rules. There is no reliable way to do that from a monthly revenue total. The destination jurisdiction has to be attached to the transaction when it is recorded.

We set books up so that happens automatically where the selling system supports it, and reconcile tax collected against tax remitted for each jurisdiction separately every month — so a city notice is answerable with a report rather than a reconstruction.

The Occupational Privilege Tax Is a Payroll-Records Problem

Denver’s Occupational Privilege Tax is charged per employee rather than on wages — a flat monthly amount for each employee earning above a threshold for work performed in the city, with a matching employer portion.

Because it keys off a monthly earnings threshold and work location, the number of chargeable employees can change month to month. Part-time staff crossing the threshold in a busy month, or hybrid staff whose Denver days vary, both change the figure. A fixed assumption set once and never revisited will drift.

The bookkeeping answer is to record payroll from actual runs with work location captured, and to track the OPT liability in its own account reconciled monthly. Our payroll processing is $50 per run plus $10 per employee. Confirm the current threshold and rates with the city — they set them, and they change them.

Job Costing for Front Range Construction

Denver’s sustained construction activity means a lot of our Colorado clients are contractors, and contractor books fail in a predictable way: costs go to general expense accounts instead of jobs, retainage is treated as a receivable that nobody chases, and margin on a job is unknown until long after it closes.

Proper job costing is not an upgrade in our pricing — it is bookkeeping done correctly. Costs coded to jobs as they are incurred, retainage tracked separately on both sides, progress billing matched to work performed. Job costing and class tracking sit on our Enterprise plan at $300/month for 20 hours, in whatever accounting system you already use.
