Remote bookkeeping — monthly close, cleanup, and books ready for your CPA.

Colorado taxes through the Colorado Department of Revenue at a 2.9% statewide base rate, with local rates stacking on top and economic nexus for remote sellers at $100,000 in sales. Filing runs monthly, quarterly, or annually by liability. Because Colorado runs an annual bracket, low-volume e-commerce and online sellers can go twelve months between returns — which is exactly how long a liability account can drift before anyone looks at it.

Employer registration runs through the Colorado Department of Labor and Employment, and the entity is registered with the Colorado Secretary of State. Home-rule cities administer their own sales tax separately from the state. The Sales and Use Tax System (SUTS) consolidates filing, but registration is still per-jurisdiction.

Marketplace sales vs. your own channels in Colorado

Marketplace facilitator rules mean large platforms generally collect and remit Colorado tax on sales made through them. Your own site, wholesale, and direct sales are a different matter — those remain yours to collect and report. Keeping the two streams separate in the books is what makes the Colorado Department of Revenue return match reality.

Colorado rates and sourcing

The Colorado statewide base rate is 2.9%. Taken alone that is low by national standards and it is genuinely misleading — local rates do most of the work in Colorado, and the combined figure at the delivery address is the only one that matters. Sourcing is where this is won or lost, and with economic nexus set at $100,000 in sales, it becomes your problem the moment that threshold is crossed.

Filing cadence in Colorado

Colorado assigns filing frequency by liability — monthly, quarterly, or annually by liability. Because Colorado includes an annual bracket, a low-volume seller here can go a full year between filings, which is exactly when a liability account drifts unnoticed. We reconcile it monthly regardless of when the return is due.

We keep the books. You run the business.

Categorization, reconciliation, month-end close, and clean financial statements — with nothing left for you to chase.

E-Commerce & Online Sellers Bookkeeping in Colorado — Frequently Asked Questions

Do e-commerce and online sellers need to register for sales tax in Colorado?

+
If you cross $100,000 in sales, Colorado generally expects you to register with the Colorado Department of Revenue and begin collecting. Physical presence also creates an obligation. We track your Colorado activity against the threshold and flag it as you approach — whether to register, and how to handle any prior period, is a decision to make with your CPA or a tax professional.

How often do e-commerce and online sellers file in Colorado?

+
Colorado sets it by liability — monthly, quarterly, or annually by liability — and moves you between brackets as volume changes, so it is worth confirming each year rather than assuming. We close the month against the Colorado Department of Revenue calendar you are actually on.

Which Colorado agencies do e-commerce and online sellers deal with?

+
Three: the Colorado Department of Revenue for sales tax, the Colorado Department of Labor and Employment for employer registration and unemployment, and the Colorado Secretary of State for the entity itself. Separate account numbers, separate portals, separate deadlines — and a notice from one tells you nothing about your standing with the other two.

Do e-commerce and online sellers pay Colorado state income tax?

+
Colorado does levy a state income tax, so there is a state return in addition to the federal one. We keep the books that those filings are built from and hand them to your CPA or tax preparer reconciled; we do not prepare or file income tax returns ourselves.

Do you prepare income tax returns for e-commerce and online sellers?

+
No. We are a bookkeeping firm, not a licensed CPA firm or a registered tax preparer, and we do not prepare or file income tax returns. We prepare and file sales and city tax returns and 1099 information returns, which are bookkeeping functions, and we hand off clean reconciled books to your CPA or tax preparer for anything income-tax related.
