Tennessee calendar and forms

Tennessee has no individual income tax return, so there is no state due date, no state extension and no state estimated payment. Form 1040 is due Thursday, April 15, 2027, the extension runs to Friday, October 15, and the four estimated payments fall on the federal dates. Tennessee adds two calendars of its own. The county property tax year bills in the fall, comes due at the end of February, goes delinquent March 1 in most counties, and gives homeowners 65 or older 35 days after that to apply for the relief credit and the freeze (verify dates). And the Department of Revenue’s year, for anyone who owns an LLC, limited partnership or corporation or grosses $100,000 in a business, lands on the same April 15 as the federal return: Form FAE 170 or FAE 183 for the franchise and excise tax, and the business tax return, both on the TNTAP portal.

The forms list is short. The Department of Revenue, the Department from here on, has nothing to do with an individual who does not own a registered entity or run a business. The forms a household meets are filed with the county trustee, the county clerk, or, for the LLC owner, the Department online.

The 2027 season, dated

How the property tax year works

The county assessor values property as of January 1, the county and city set their rates in the summer, and the trustee mails one bill for the calendar year in the fall. The bill is payable through the end of February with no discount for paying early; on March 1 it is delinquent and interest begins (verify). The relief and freeze applications are tied to that date: 35 days after delinquency, with the tax paid. A homeowner who disagrees with the appraisal does not argue with the bill; the appeal is to the county board of equalization in the spring, before the bill exists.

For the federal return the question is which year the payment falls in. A homeowner who pays the October bill in December deducts it on the 2026 Schedule A; one who waits until February deducts it in 2027. Because a Tennessee SALT line has no state income tax in it, few households itemize, but a household near the line can pay two bills in one calendar year, December 2026 and December 2027, to bunch deductions into one year. Run the arithmetic once; for most Tennessee households the standard deduction wins either way.

Filing the federal return from Tennessee

The federal return is filed from Tennessee as from anywhere, electronically, through a preparer, commercial software or the IRS Free File partners for those under the income limit. Tennessee was part of the IRS Direct File program for the 2025 filing season, federal return only; the IRS has since ended the program. The one thing a Tennessee return does differently is the SALT line: with no state income tax, the deduction is property tax plus the sales tax election, from the IRS tables at 7% plus the local rate, with the actual tax on a car or other large purchase added on top. Keep the county clerk’s receipt for any vehicle bought in 2026.

Federal estimated payments matter more here than in a state with withholding on pensions, because a Tennessee retiree’s only withholding is what the custodian takes for the IRS. A household living on Social Security, an IRA and a brokerage account with no withholding meets the underpayment penalty in April unless it pays estimates or has tax withheld from the IRA withdrawal. The safe harbors are in Estimated payments; the simplest Tennessee fix is to have the custodian withhold enough in December to cover the year.

The Department is reached through its TNTAP portal for franchise and excise, business and sales tax accounts, and its help articles at revenue.support.tn.gov answer most questions in a paragraph. Property tax questions go to the county trustee and assessor, not the Department; the Comptroller’s Division of Property Assessments runs the relief and freeze programs and has a status search for relief applications at tncot.cc/taxrelief.
