Who handles property taxes in Gallatin?

Sumner County Assessor of Property

The Sumner County Assessor determines the value and classification of taxable property, except for property assessed by the State of Tennessee. The assessor’s office maintains property information, supports the county’s GIS and assessment systems, administers programs such as Greenbelt applications and provides the first step for owners who believe a value or classification is incorrect.

The assessor’s office is listed at 355 N. Belvedere Drive, Room 206, Gallatin, TN 37066, with a published phone number of 615-452-2412 and regular hours of Monday through Friday, 8 a.m. to 4:30 p.m. Verify hours before visiting.

Sumner County Trustee

The Sumner County Trustee collects county property taxes, provides payment options and administers or assists with certain tax-relief and tax-freeze applications. The trustee’s published contact number is 615-452-1260. County tax payments may be made online, by mail, in person, by telephone or through listed local banks, although card and other processing fees may apply.

City of Gallatin Recorder’s Office

The City of Gallatin Recorder’s Office collects city property taxes for property within the city. The city’s published 2026 tax ordinance sets the Gallatin municipal property-tax rate at $0.5295 per $100 of taxable property. The city identifies the Sumner County Assessor as the official responsible for assessing property within Gallatin’s corporate limits.

The Recorder’s Office is listed at 132 W. Main Street, Room 111, Gallatin, TN 37066, with a published phone number of 615-451-5895 and hours of Monday through Friday, 7:30 a.m. to 4:30 p.m. The city provides online links for searching or paying city real-estate and personal-property taxes. Confirm the current payment links and office availability before submitting a payment.

How Tennessee property taxes are calculated

Tennessee uses four basic steps:

1. The county assessor determines an appraised value.
2. State law applies an assessment ratio based on the property class.
3. The appraised value multiplied by the ratio produces the assessed value.
4. The local tax rate is applied to the assessed value.

For example, a residential property appraised at $400,000 has an assessed value of $100,000 because residential property is assessed at 25%. A tax rate of $2.50 per $100 of assessed value would produce a $2,500 tax amount for that rate. The example is provided by the Tennessee Comptroller and is not a Gallatin tax estimate.

Common assessment ratios

Property class — State assessment ratio

Residential property — 25%

Farm property — 25%

Commercial and industrial real property — 40%

Business personal property — 30%

Public utility property — 55%

A business owner should not assume that a residential calculation applies to commercial real estate, equipment, furniture, computers or other tangible personal property. Classification errors can affect the tax bill and may be a basis for an appeal.

City versus county taxes

A Gallatin property may receive separate county and city tax charges because the county and municipality fund different services and adopt their own rates. The combined amount depends on the property’s assessed value, jurisdiction, classification and applicable tax districts. Do not calculate a final bill using only the City of Gallatin rate or only a county rate.

The official county rate for the applicable tax year should be confirmed through the Sumner County Commission, Trustee or current tax bill. This is especially important after a reappraisal or budget action.

How to look up a Sumner County property assessment

Use the Sumner County Assessor’s property-information, GIS or Tennessee Property Assessment Data search tools to locate a parcel. Search information may include the owner of record, parcel identifier, property address, appraised value, assessed value, classification, land and improvement information and sales history, depending on the system.

When reviewing a record, check:

• The property address and parcel number.
• Ownership and mailing information.
• Land and improvement values.
• Property classification.
• Exemptions, Greenbelt or other status indicators.
• The tax year shown by the search tool.
• Whether the value is an estimate, an assessment-roll value or a final tax amount.

The assessor’s office says Sumner County operates on a five-year reappraisal cycle and identifies 2029 as the next scheduled reappraisal after the current cycle. Individual values can still change because of appeals, corrections, new construction, additions, removals or changes in property characteristics.

How to pay property taxes in Gallatin

Sumner County property taxes

The Sumner County Trustee lists online, mail, in-person, telephone and participating-bank payment options. Online card payments may carry a processing fee. The trustee also states that up to five partial payments may be made by check or cash, but any unpaid portion is subject to interest beginning March 1. Confirm current rules, payment limits and fees before relying on a partial-payment plan.

For a payment question, contact the Sumner County Trustee. For a mailing-address change, contact the Assessor of Property because the assessor maintains the tax roll used to print and mail bills.

City of Gallatin property taxes

City property taxes may be searched and paid through the City of Gallatin Recorder’s Office. The city also lists payment by mail, in person and through its online payment links. If a property owner is unsure whether a bill is a city or county obligation, compare the bill’s issuing office and contact the relevant collector before paying.

Property-tax deadlines and delinquency

Sumner County’s assessment schedule identifies February 28 as the last day to pay the preceding year’s taxes without interest. The City of Gallatin states that taxes are due by the last day of February and begin accruing interest on March 1. Tennessee law does not require a tax notice to be mailed, so failure to receive a bill does not eliminate the payment obligation.

Because deadlines can be affected by weekends, holidays, payment-posting rules or updated local instructions, verify the exact deadline on the current bill or with the collecting office.

What to do if you disagree with an assessment

An assessment appeal is different from a complaint about a tax rate or a payment-processing problem. The assessor determines value and classification; the county commission and city council establish local rates.

Step 1: Request an informal review

Contact the Sumner County Assessor’s Office or submit the office’s current informal-review request. Useful evidence may include recent sales of comparable properties, a private appraisal, photographs and documentation showing a physical or classification issue. The assessor’s office says informal reviews are the first step for owners who believe the value is inaccurate.

Step 2: Appeal to the Board of Equalization

If the informal review does not resolve the issue, an owner may appeal to the Sumner County Board of Equalization during the applicable appeal period. The assessor’s published schedule stated that informal reviews for tax year 2026 began May 4, 2026, ended May 29, 2026, and that the Board of Equalization would begin meeting June 1, 2026. These dates should be rechecked before publication or use because appeal windows are time-sensitive.

Continue paying any undisputed tax amount by the deadline unless the responsible office or qualified adviser gives different instructions. An appeal does not automatically suspend all payment obligations.

Property-tax relief, tax freeze and Greenbelt programs

Tennessee’s Property Tax Relief Program may assist qualifying low-income elderly and disabled homeowners, disabled veterans and certain surviving spouses. It is a state reimbursement program—not a general exemption—and eligible applicants remain responsible for receiving and paying their tax bills according to local requirements. Applications are handled through local collecting officials, including county trustees and city collecting officials.

Tennessee also authorizes participating counties and municipalities to offer a Property Tax Freeze for qualifying homeowners age 65 or older who meet ownership, principal-residence and income requirements. The Comptroller lists Sumner County’s 2026 income limit as $48,550. Confirm whether the specific city portion of a bill participates and whether the applicant meets all current requirements..

Disabled-veteran relief has separate eligibility rules, including qualifying service-connected disability categories and use of the property as a primary residence. Applicants should work through the Sumner County Trustee or city collecting official and use current state forms and documentation.

For agricultural, forest or open-space land, the Greenbelt program may value qualifying land according to present use rather than highest and best use. Greenbelt eligibility, deadlines and rollback-tax consequences should be confirmed with the Sumner County Assessor before changing the property’s use or status.

Guidance for business owners

Businesses in Gallatin and Sumner County should distinguish among real property, business personal property and any other taxable classifications. The Sumner County Assessor states that business owners are required to file a tangible personal-property schedule annually for the county where the business is located. The assessor’s office can explain the current filing process, deadlines and documentation.

Keep records for equipment purchases, disposals, transfers, leases and business locations. If an assessment appears to include property that was sold or removed, contact the assessor promptly and retain supporting documentation.
