Tennessee Department of Revenue: Taxes, Licensing, and Collections

The Tennessee Department of Revenue (TDOR) administers the state's tax laws, issues business licenses, and enforces collections against delinquent taxpayers and entities. Its authority spans individual consumers, businesses, and nonprofit organizations operating within Tennessee's borders. The department operates under Title 67 of the Tennessee Code Annotated, which governs the full range of state tax obligations. Understanding TDOR's structure, enforcement mechanisms, and jurisdictional limits is essential for any entity conducting taxable activity in Tennessee.

Definition and scope

The Tennessee Department of Revenue is a cabinet-level executive agency responsible for collecting state and local taxes, administering licensing programs, and enforcing compliance through audit and collections activity. The department's statutory authority is established under Tennessee Code Annotated Title 67.

TDOR's primary revenue instruments include:

  1. Sales and Use Tax — The state base rate is 7%, with an additional local option rate up to 2.75%, for a maximum combined rate of 9.75% (Tennessee Department of Revenue, Sales Tax Overview).
  2. Franchise and Excise Tax — A two-part tax applied to corporations and certain other entities doing business in Tennessee; the excise tax rate is 6.5% of net earnings, and the franchise tax rate is $0.25 per $100 of net worth or real and tangible property in Tennessee (TDOR, Franchise and Excise Tax).
  3. Business Tax — A gross receipts tax imposed on most businesses selling goods or services in Tennessee, classified across five rate classifications.
  4. Hall Income Tax — Tennessee phased this tax out completely as of January 1, 2021, eliminating the state's tax on interest and dividend income (TDOR, Hall Income Tax).
  5. Motor Fuel Taxes — Collected at the point of distribution and applied per gallon to gasoline, diesel, and alternative fuels.
  6. Tobacco and Alcoholic Beverage Taxes — Excise taxes collected at the wholesale level.

The department also administers the issuance and renewal of business licenses required under state law, including standard business licenses and specialized permits for regulated industries.

How it works

TDOR operates through three functional divisions: Tax Administration, Motor Carrier and International Registration, and Office of General Counsel. Tax Administration handles returns processing, audits, and taxpayer services. The Motor Carrier division manages the International Fuel Tax Agreement (IFTA) and the International Registration Plan (IRP) for commercial vehicles.

Taxpayers file returns and remit payments through the Tennessee Taxpayer Access Point (TNTAP), the department's online portal. Electronic filing is mandatory for most business tax types once a business exceeds defined filing thresholds. Audit selection is risk-based, drawing on discrepancies between filed returns, third-party data, and industry norms.

When a taxpayer fails to file or underpays, TDOR issues a notice of assessment. The taxpayer has 30 days to either pay or file a written protest. Protests are reviewed by the Office of Appeals within TDOR before any case proceeds to the Tennessee State Board of Equalization or chancery court.

Collections enforcement includes liens against real and personal property, levy of bank accounts, garnishment of wages, and revocation of business licenses. TDOR may also refer cases to the Tennessee Attorney General for civil action.

Common scenarios

Business registration and initial licensing — A new entity registering with the Tennessee Secretary of State must separately obtain a business license from the local county clerk and register with TDOR for applicable tax accounts. The standard business license threshold is gross receipts exceeding $10,000 (TDOR, Business Tax Guide).

Sales tax nexus disputes — Following the U.S. Supreme Court's decision in South Dakota v. Wayfair (2018), Tennessee enforces an economic nexus standard requiring out-of-state sellers with more than $100,000 in Tennessee sales or 200 transactions to collect and remit sales tax.

Audit of franchise and excise tax — Multistate corporations are subject to apportionment audits. Tennessee applies a single-sales-factor apportionment formula for most industries under Tenn. Code Ann. § 67-4-2012.

Delinquent collections — A business that fails to remit collected sales tax is subject to a penalty of 5% of the unpaid tax per month, up to 25% of the total liability, plus interest (TDOR, Penalty and Interest).

Taxpayer protest and appeals — A taxpayer disputing an assessment files a written protest with the Commissioner of Revenue within 30 days of receiving the assessment notice, initiating the administrative appeals process.

Decision boundaries

Scope and coverage — TDOR's authority applies exclusively to taxes and fees imposed under Tennessee state law. Federal tax obligations — including federal income tax, federal payroll taxes, and excise taxes administered by the Internal Revenue Service — fall outside TDOR's jurisdiction entirely. Interstate commerce disputes involving apportionment may involve coordination with revenue agencies in other states but are resolved under Tennessee law as applied to multistate entities.

What TDOR does not administer — Property taxes in Tennessee are administered at the county level through county assessors and county trustees, not TDOR. Local business license fees collected by county clerks are distinct from state business tax accounts. Licensing for professions such as medicine, law, and contracting is handled by the Tennessee Department of Commerce and Insurance, not TDOR.

Entity type distinctions — Sole proprietors and general partnerships are subject to business tax but are not subject to franchise and excise tax unless they elect corporate treatment. LLCs with a single member treated as a disregarded entity follow different filing protocols than multi-member LLCs taxed as partnerships or corporations.
