Bookkeeping Services in Denver

What Do Bookkeeping Services in Denver Include?

Bookkeeping services in Denver cover monthly categorization, bank reconciliation, payroll support and financial reporting, plus one thing most cities never require: a sales tax return filed directly with the City and County of Denver. Denver is a home rule jurisdiction, so it collects its own tax and runs its own filing system. That local layer is the only real difference between bookkeeping services Denver Colorado businesses need and bookkeeping anywhere else. Underneath sits the same outsourced bookkeeping process we run nationally.

What Does a Bookkeeper in Denver Cost?

A bookkeeper in Denver earns an average of $59,520 a year, or $28.62 an hour, according to the Bureau of Labor Statistics survey published in May 2025. Across Colorado the average is $27.19 an hour. Add the employer share of Social Security and Medicare at 7.65 percent and the 0.44 percent employer FAMLI premium, and one in-house bookkeeper passes $64,000 before software or health insurance.

What Makes Bookkeeping in Denver Different?

Denver CO bookkeeping runs on two calendars, the City’s and the State’s, and missing either creates a penalty. Colorado adds two statewide charges that catch new employers and online sellers by surprise.

Denver Home Rule Sales Tax

Denver is a home rule city, so it administers its own sales tax instead of letting Colorado collect it. The combined rate on a general Denver sale is 9.15 percent: 5.15 percent Denver, 2.90 percent State, 1.00 percent RTD and 0.10 percent Cultural Facilities District. Current periods file through Denver’s eBiz Tax Center, but refund claims, amendments and delinquent periods must go directly to the City.

Denver Occupational Privilege Tax

Denver Occupational Privilege Tax is a flat monthly charge on every employee earning at least $500 in a month for work performed in Denver. The employee pays $5.75 and the employer pays $4.00. Owners and partners owe the employer portion even when they earn less than $500.

Colorado Retail Delivery Fee (New Rate 2026)

The Colorado Retail Delivery Fee is $0.31 on every retail delivery to a Colorado address from July 2026 through June 2027, up from $0.28. It applies per delivery, not per item. The fee escapes State sales tax, but home rule cities including Denver may tax it, so one delivery can carry both the fee and tax on the fee.

Colorado FAMLI Premiums

Colorado Family and Medical Leave Insurance takes 0.88 percent of each employee’s wages, split evenly at 0.44 percent employer and 0.44 percent employee. Businesses with nine or fewer employees send only the employee share. Premiums apply to wages up to the federal Social Security wage cap.

Industries We Support in Denver

Local bookkeeping services Denver owners search for usually means someone who knows the City’s filing system, not someone with a desk on Colfax. We work remotely across Denver, Aurora, Lakewood, Littleton and Centennial, including construction and restaurant operators.

Real Estate and Property Management

Denver rental portfolios need rent roll reconciled to the bank, deposits held separately, and capital improvements split from repairs before year end. Our property management accounting team maps every property to its own profit and loss statement.

E-commerce and Retail

Bookkeeping in Denver: Frequently Asked Questions

How much do bookkeeping services cost in Denver?

Outsourced bookkeeping in Denver costs less than hiring in house, where the average bookkeeper earns $59,520 a year in base pay alone. Our plans start under $250 a month and include the Denver City sales tax filing most providers charge extra for.

Monthly rates are set by transaction volume, number of accounts, and whether payroll and sales tax filing are included. The monthly bookkeeping packages Denver owners choose most often bundle all three into one fee.

The mean hourly wage is $28.62 in the Denver metro and $27.19 across Colorado, according to the Bureau of Labor Statistics May 2025 survey. An independent bookkeeper charges above that because their rate covers their own taxes, software and unbilled time.

Check whether they file directly with the City and County of Denver, not only with the State, because that gap causes most Denver penalties. Any bookkeeper Denver businesses hire should also handle Occupational Privilege Tax registration.

Hire one as soon as you register for Denver sales tax or run your first payroll, because both create a filing obligation immediately. Waiting until tax season means paying catch up bookkeeping Denver rates on a year of unreconciled transactions.

Yes. Small business bookkeeping Denver clients make up most of our Colorado work, from shops in Littleton to service firms staffed across Aurora and Lakewood. We price bookkeeping services for small business Denver owners on the same fixed fee basis as larger accounts.

Yes. Online bookkeeping in Denver works because the filings are already electronic, with the eBiz Tax Center taking sales tax and Occupational Privilege Tax returns and QuickBooks Online or Xero syncing your bank feed.

No. Software can categorize a transaction, but it cannot decide whether a shipment into Colorado carries the retail delivery fee or whether a part time employee crossed the $500 Occupational Privilege Tax threshold.
