Collin County's Seat
McKinney, the seat of Collin County, had about 236,000 residents in the Census Bureau's 2025 estimate. It combines a historic courthouse square and Victorian neighbourhoods with fast-growing subdivisions, a corporate corridor along State Highway 121 and farmland on its eastern and northern edges. McKinney National Airport began commercial passenger service on November 11, 2026, with an Avelo flight to Fort Myers. BOMCAS works with McKinney clients remotely.

McKinney Taxes
Texas has no income tax. Companies file the franchise tax report, and sales are taxed at 8.25 percent: 6.25 percent for the state, 1 percent for the city and half a cent each for the McKinney Economic Development Corporation and Community Development Corporation. McKinney is not in DART. Hotel stays carry 7 percent city tax and 6 percent state tax. Property is appraised by the Collin Central Appraisal District, and much land on the city's edges carries agricultural or open-space valuation.
Our McKinney Clients
We work with shops and restaurants on the square, breweries, event and wedding venues, homebuilders and contractors, aviation businesses at the airport, professional practices, ranchers and landowners, corporate employees, retirees and families who have moved from other states or countries.
Parts of the City
The downtown square, with the old Collin County Courthouse at its centre, holds shops, restaurants and the cultural district. Craig Ranch and the Highway 121 corridor in the southwest hold offices, medical buildings and newer housing. Stonebridge Ranch and Eldorado are established master-planned areas, and the airport lies to the southeast, with new subdivisions spreading east and north toward the county line.
Typical First Questions
A family offered a price for their grazing land. A pilot who bought a plane in another state and has a letter from the Comptroller. A venue unsure what to tax in its wedding packages. A brewery whose excise reports and books disagree. We start by reviewing recent filings and records and agreeing on priorities.

Working With BOMCAS
All our work with McKinney clients happens remotely, through secure uploads, video calls and shared cloud books. We prepare returns, keep books, run payroll and plan. Legal documents, appraisals and representation in hearings are matters for your attorney or appraiser.
How BOMCAS Helps in McKinney
For most McKinney businesses the base is bookkeeping that tracks inventory, jobs and deposits, payroll for crews, taproom staff and, on the edges of town, ranch hands, and sales tax on venues, aircraft and retail. From those records come the business return and franchise tax report and the owners' personal returns, and tax planning turns them into decisions about land sales, aircraft and estates. Unfiled years or assessments are handled under back taxes and late filing, and newcomers and investors from abroad use our cross-border tax service.
Statewide detail on business tax, personal returns, sales and use tax, bookkeeping, payroll, tax planning, back taxes and cross-border matters is on our Texas pages.
