Trailside is one of Thornton's distinctive business communities. Fast-growing residential and retail communities north of 144th. Whether you run a storefront, a service company, or a home-based venture here, Tides Bookkeeping keeps your books accurate, categorized, and ready for tax season - without you ever leaving Trailside.
As part of the greater Thornton, CO economy within Adams County, Trailside businesses share the same Colorado tax and compliance landscape as the rest of the area. Our remote-first process means you get a dedicated bookkeeper and clean monthly financials no matter where in Thornton you are located - reconciled accounts, categorized transactions, and monthly profit-and-loss and balance-sheet reporting you can actually use.
Colorado has a low 2.9% state sales-tax base and a flat state income tax (4.4% as of 2026, subject to TABOR adjustment) - but the real complexity is its home-rule cities. Many Colorado municipalities administer and collect their own sales tax separately from the state, so businesses can owe filings to both. We track your revenue by jurisdiction and keep your books reconciled so your state and city sales-tax filings stay accurate and on time.
