Knoxville draws plenty of new residents comparing notes with pricier cities, and the sticker shock usually runs in a happy direction. A mortgage payment alone rarely tells the full story once property taxes, utilities, and Tennessee's sales tax structure enter the picture. Newcomers who budget only for principal and interest often find their first full year of ownership more expensive than expected.
What follows breaks down the recurring costs that shape a realistic Knoxville budget.
Key Takeaways
- Property taxes: Knox County's 2026 rate sits at $1.5540 per $100 of assessed value, split between general fund, debt service, and schools.
- No state income tax: Tennessee collects no state income tax, which changes the math on take-home pay compared to many relocation markets.
- Sales tax: Knoxville's combined state and local sales tax rate runs close to 9.25 percent on most purchases.
- Utilities: KUB bills electric by the kilowatt-hour and water by the CCF, with slightly higher water rates for homes outside city limits.
Property Taxes and What They Fund
How the Rate Breaks Down
- General fund: Roughly 43 percent of the total rate covers day-to-day county operations.
- Debt service: About 26 percent goes toward paying down county bond obligations.
- School funding: The remaining 31 percent supports the general purpose school fund.
Tennessee's Tax Structure Changes the Math
Where Tennessee Collects Instead
- State sales tax: Tennessee applies a 7 percent base rate on most retail purchases statewide.
- Local option tax: Knox County adds its own local rate, pushing the combined total close to 9.25 percent.
- Grocery exceptions: Food items carry a reduced state rate compared to general merchandise.
Utility Costs Through KUB
Rate Details Worth Knowing
- Electric usage: Standard service runs about 12.6 cents per kilowatt-hour on top of the monthly basic charge.
- Water inside city limits: Homes billed at $2.80 per CCF for the first two units, then $4.55 per CCF beyond that.
- Water outside city limits: Rates run slightly higher, at $3.05 and $5.35 per CCF, with a higher basic charge too.
Everyday Costs That Add Up
Categories Worth Budgeting For Early
- Homeowners insurance: Rates depend on a home's age, roof condition, and distance from a fire station.
- HOA dues: Some newer subdivisions carry monthly or annual dues that cover shared amenities.
- Vehicle costs: Fuel and vehicle wear add up differently depending on which side of Knoxville a household calls home.
How to Put Together a Realistic Monthly Budget
A Simple Budgeting Checklist
- Fixed costs: Mortgage, property tax, and insurance premiums that stay consistent month to month.
- Variable utilities: Electric, water, and any additional services like trash or stormwater fees.
- Discretionary spending: Groceries, dining, and the everyday costs that shift with lifestyle and neighborhood.
