Thompson’s Station homes carry a combined rate of 1.403 per $100 of assessed value for tax year 2025. Of that, 1.30 is Williamson County’s rate and 0.103 is the town’s, a smaller city levy than Franklin, Brentwood, Nolensville or Fairview charge. Unincorporated Williamson County pays the county’s 1.30 alone, so living inside the town limits adds 0.103 per $100 assessed.

Assessor of Property Brad Coleman values homes from 1320 West Main Street, Suite 300, in Franklin, and Trustee Karen L. Paris bills and collects from Suite 203. For a household new to the town, the first bill comes from that Suite 203 office, and the closing papers from the purchase belong in the file for the personal return that year.

For tax year 2026 the standard deduction is $16,100 for single filers and married people filing separately, $32,200 for a married couple filing jointly, and $24,150 for a head of household. The amounts come from IRS Revenue Procedure 2025-32, released in October 2025.

Those figures are the baseline Haven measures a Thompson’s Station return against. A family that moved to town during the year, bought its first home or added a child can find its filing status or deduction picture different from the year before, and the planning that comes with each return asks whether withholding should change to match. With 1,643 more residents than at the 2020 census base, the town has plenty of households filing from a new address. Tax planning is where that first year gets set up properly.

Three years from filing is the IRS default, and some records need longer. If more than 25% of gross income was left off a return, the window stretches to six years; a claim for a worthless security or a bad debt calls for seven; and when no return was filed, or a fraudulent one was, there is no limit at all.

The practical problem is usually finding the paper, not knowing the rule. Documents a Thompson’s Station client sends through Haven’s secure client portal arrive in one place, and questions about an older year that is still open can go to the firm’s tax advisory side, which the old site says offers clear answers to tax questions. The town is 7.7 miles from Franklin’s center in a straight line.
