Colorado · Sales tax registration
Colorado sales tax registration, done for you.
Colorado registers through MyBizColorado, which starts you with the Department of Revenue and, if you are hiring, the Department of Labor and Employment at the same time. What it does not do is keep them joined afterwards, which is the single most useful thing to understand about Colorado before you begin.
Who you are dealing with
Colorado Department of Revenue
- Handles:
- Sales tax account and licence
- System:
- MyBizColorado, then Revenue Online
- Form:
- Register through MyBizColorado. Account maintenance and closure afterwards run through Revenue Online, or on Form DR 1108
State fee. Colorado charges for a sales tax licence. We confirm the current amount with the Department of Revenue before filing and pass it through at cost.
When you have to register
Register before making taxable sales in Colorado. If you are also hiring, note that Colorado needs three payroll accounts rather than two, because FAMLI paid family leave sits alongside withholding and unemployment.
What comes next
Not applicable to a registration. Worth knowing now: the closure request is due within 30 days of closing, the final return itself must state that the business is closing with the effective date, and periods with no tax due still need a zero return.
How long it takes
Colorado does not publish a registration turnaround we could confirm. It does publish something rarer at the other end: a closure submitted through Revenue Online is effective the next business day, while the paper DR 1108 takes longer. Online is the better route in both directions.
What we do
We work out exactly which accounts you need, prepare and submit each registration, and hand you the account numbers, rates, and deposit schedules your payroll system asks for. One flat price per account, and any state fee passed through at cost.
What makes Colorado harder than average
- One registration, several separate closures. MyBizColorado can start Revenue and Labor and Employment together. Nothing closes them together, and that asymmetry catches people who remember signup being simple.
- Zero returns are not optional. Where no tax is due, Colorado still wants a return showing zero before an account will close cleanly. A business that stops filing when it stops selling builds a backlog.
- The state tells you which route is slower, which is unusual and worth acting on. Revenue Online closures are effective the next business day and the paper DR 1108 takes longer. Assume the same preference applies at registration.
- If you hire, count to three. Withholding at Revenue, unemployment at Labor and Employment, and FAMLI. Counting to two is how Colorado businesses end up partly registered.
Questions and answers
Is there a fee for a Colorado sales tax licence?
Yes. Colorado charges, unlike many states. We confirm the current amount with the Department of Revenue before filing and pass it through at cost.
Does one registration cover payroll too?
MyBizColorado can start the Department of Revenue and the Department of Labor and Employment together. Be aware that payroll in Colorado means three accounts, because FAMLI paid family leave is separate again.
What is the fastest way to handle this account?
Online, in both directions. Colorado states that a closure through Revenue Online is effective the next business day while the paper DR 1108 takes longer, which is a strong hint about how the systems are weighted.
Do I have to file if I had no sales?
Yes. Colorado requires a zero return where no tax is due, and an account will not close cleanly with those periods outstanding.
What do you need from me to start?
The legal name and FEIN, entity type, Colorado locations, what you sell, the date taxable sales begin, and whether you will also have employees.
