A $250,000 Memphis house is not taxed on $250,000 — Tennessee only taxes a quarter of it. The state’s 25% residential assessment ratio, combined with the stacked Memphis-city and Shelby-County levies quoted per $100 of assessed value, makes the headline rate almost useless for comparing Memphis against cities that quote a simple percentage of market value. This estimator does the conversion for you: enter the appraised value and the combined rate, and it returns the annual bill and the true effective rate on market value (about 1.52% at the default rate).
Tennessee’s assessment system, decoded
Unlike states that tax a property at close to its full market value, Tennessee requires a formal appraisal by the county assessor and then taxes only a fraction of it. For residential and farm property, that fraction is 25% (commercial and industrial property is assessed at 40%, and public utility property at 55%). The ratios are set by state law and applied uniformly across all 95 counties — the framework is administered by the Tennessee Comptroller’s Division of Property Assessments.
The result is that the headline “tax rate” you see quoted in Memphis is a per-$100-of-assessed-value figure, not a percentage of market price. To compare it to other cities that advertise effective rates (as a percentage of market value), you need to apply the 25% ratio first.
The calculation step by step
assessed value = appraised value × 0.25
annual tax = assessed value × (combined rate ÷ 100)
effective rate = annual tax ÷ appraised value
The combined rate defaults to about $6.09 per $100, which represents the Memphis city rate plus the Shelby County rate. Adjust it to the current certified rate for the most accurate estimate.
Worked example
A Memphis home appraised at $250,000:
- Assessed value: $250,000 × 25% = $62,500
- Annual tax at $6.09 per $100: $62,500 × 0.0609 = $3,806
- Effective rate on market value: $3,806 ÷ $250,000 = 1.52%
For a second example, a lower-priced home at $150,000:
- Assessed value: $150,000 × 25% = $37,500
- Annual tax at $6.09 per $100: $37,500 × 0.0609 = $2,284
- Effective rate: $2,284 ÷ $150,000 = 1.52%
The effective rate is consistent because the 25% ratio and per-$100 rate are uniform — only the absolute dollar amount changes with home value:
| Appraised value | Assessed (25%) | Annual tax @ $6.09/$100 | Monthly escrow |
|---|---|---|---|
| $150,000 | $37,500 | $2,284 | $190 |
| $250,000 | $62,500 | $3,806 | $317 |
| $400,000 | $100,000 | $6,090 | $508 |
| $600,000 | $150,000 | $9,135 | $761 |
The monthly column is the number mortgage lenders fold into an escrowed payment — on a mid-priced Memphis home, property tax adds several hundred dollars a month to the true cost of ownership.
Reappraisal and why the rate moves
Shelby County reappraises property on a four-year cycle. When appraisals jump, Tennessee’s truth-in-taxation rules require each taxing body to calculate a certified tax rate — the rate that would produce the same total revenue on the new, higher appraisals. Rates therefore tend to fall in reappraisal years even as individual bills rise or fall with each home’s relative change. Practical consequence: never carry a rate from a news article across a reappraisal year; pull the current certified rate from the Shelby County Trustee and type it into the rate field — the tool recomputes instantly.
Who pays what in Shelby County
Memphis proper sits inside both the Memphis city limits and Shelby County, so city homeowners pay two distinct tax levies — one to each government. Properties in unincorporated Shelby County (outside city limits) pay only the county portion, making their effective rate lower than that of city homeowners.
A handful of smaller municipalities like Germantown, Collierville, and Bartlett also have their own city rates layered on top of the county rate, separate from Memphis’s city rate.
Exemptions and relief programs that reduce the bill
Tennessee offers several programs that can significantly cut or cap a Memphis property tax bill:
- Tax Relief: Available to elderly homeowners (65+), disabled homeowners, and disabled veterans below income thresholds. Provides a reimbursement of a portion of taxes paid. Administered by the Shelby County Trustee.
- Tax Freeze: Freezes the tax amount for qualifying seniors, so increases in appraised value do not increase the bill. Income limits apply.
- Greenbelt: Agricultural or open-space land can qualify for assessment at agricultural value rather than market value, dramatically lowering the bill.
This estimator computes the standard amount without any relief. Contact the Shelby County Assessor or Trustee to determine which programs apply to your situation.
