State Tax Impact Calculator
See the whole picture.
Use our state tax impact calculator to compare income, property and sales taxes before you move. Start with your own estimates, then see the monthly and five-year difference.
Free manual estimator · No signup · Reviewed October 5, 2026
How do you compare taxes before moving? Add your estimated annual state and local income tax, property tax and sales tax for each location. Subtract the destination total from the current total. A positive difference means lower selected taxes at the destination under those assumptions.
Start with what you know
Use a recent tax return, property-tax bill and a rough spending budget.
Fill the gaps carefully
Enter your own estimates. A labeled example shows how the numbers work.
Compare the difference
See the annual cost, monthly equivalent and five full years side by side.
Build your state tax estimate
Choose two states, then enter three types of household costs. State names label your comparison; they do not load rates or calculate tax brackets.
Example-based scenario: these are invented demonstration figures, not current state rates or a prediction of your tax bill.
Your saved state tax map
Each calculation adds its two state estimates. The map compares saved entries with the same income, income type and planning year. Keep household assumptions consistent.
Select a state to prepare another comparison. Unknown figures stay blank.
How to use the state tax impact calculator
Income tax
First, find total state and local income-tax liability on a recent return or a current estimate. Do not enter only the refund, balance due or paycheck withholding.
For the destination, use its official tax instructions or a household estimate. The optional helper multiplies annual income by your own effective-rate assumption.
Property tax
Next, use the expected annual bill for the home you would occupy. Check exemptions, assessment rules and local charges with the relevant tax office.
If you rent and pay no property-tax bill directly, use zero here. Then compare rent separately. A seller’s current bill may not match a new owner’s future bill.
Sales tax
Finally, estimate purchases subject to sales tax and enter a matching combined state and local rate. Leave exempt spending out of that amount.
For example, $1,500 of taxable purchases each month at an assumed 7% rate equals $105 monthly, or $1,260 annually. This is arithmetic, not a quoted local rate.

State tax impact calculator examples
Both examples use invented numbers. State names are scenario labels, and none of the rates or bills below is a verified state average.
Lower income tax, higher property tax
Current: $8,000 income tax + $6,000 property tax + $1,200 sales tax = $15,200 a year.
Destination: $0 income tax + $12,000 property tax + $1,600 sales tax = $13,600 a year.
$1,600 lower each yearThat is about $133 a month and $8,000 over five years at 0% change. Higher property tax offsets much of the income-tax reduction.
Keep housing in the wider budget
Current: $4,000 income tax + $0 direct property tax + $900 sales tax = $4,900 a year.
Destination: $2,000 income tax + $0 direct property tax + $1,050 sales tax = $3,050 a year.
$1,850 lower each yearThat is about $154 a month. However, a $200 monthly rent increase would cost $2,400 a year and outweigh this tax saving.
What the estimate includes
Annual selected taxes = income tax + property tax + (taxable spending × sales-tax rate ÷ 100)
The state tax impact calculator subtracts the destination total from your current total. It divides that difference by 12 for a monthly equivalent. Therefore, this number is not a prediction of when bills will arrive.
For five full years, year one uses your starting totals. Each later year multiplies both totals by one plus your annual change assumption. We then add the five annual differences. At 0%, five-year savings equal annual savings multiplied by five.
The tool excludes federal income tax, payroll and self-employment taxes, business entity taxes, estate taxes, vehicle taxes, transfer taxes and fees. Capital gains and retirement rules are included only to the extent that your own income-tax entry reflects them. It does not calculate deductions, exemptions, credits or tax brackets.

What if you move halfway through the year?
A full-year comparison helps with future budgets. However, it does not determine the tax you owe in the moving year. Residency, work location, income source and timing can affect both state returns.
For example, California’s part-year guidance distinguishes income received while resident from California-source income while nonresident. Other states have their own rules. Simply multiplying a full-year bill by months lived in a state can give the wrong answer.
Keep move dates, work-location records and income documents. Then use the state tax-residency change checklist and new-resident guides to plan the next steps.
Common tax comparison questions
Does moving to a state with no income tax always save money?
No. A higher property-tax bill or more sales tax can offset the income-tax reduction. Compare all three amounts, then check housing, insurance and moving costs in your wider budget.
Can I use estimated values if I do not know my tax bill?
Yes. Enter your own estimates, use the optional effective-rate helper, or load a labeled example to learn the tool. Replace the sample figures before making a decision. The calculator does not fetch live tax rates.
What is the difference between withholding and tax owed?
Withholding is money paid toward your tax during the year. Your final liability is the tax owed after applicable deductions and credits. A refund or balance due is only the difference between payments and that liability.
How should renters enter property tax?
Enter zero if you do not pay a property-tax bill directly. Rent may still reflect the landlord’s costs, so compare the full rent payment separately in your housing budget.
Does this calculate retirement or self-employment taxes?
No. Those modes change the guidance and keep saved scenarios separate. Supply the state and local income-tax estimate for your income mix. Federal income tax, payroll tax and federal self-employment tax are outside this tool.
Can I calculate taxes for the year I move?
This calculator compares full years. A midyear move may involve residency, work location and income-source rules in both states. Use the tax-residency checklist and official state instructions for the moving year.
Are the five-year results a forecast?
No. They extend your starting estimates using one annual change assumption for both states. A zero percent change keeps all amounts constant. Changes in tax law, income or property assessments are not predicted.
Why are some states grey on the map?
Grey means there is no comparable saved estimate for the selected income, income type and planning year. It never means tax-free. The map displays your saved inputs, not an automatic ranking of state tax laws.
