Tax Implications of Moving to a New State
Quick Answer
Moving to a new state changes your state income tax obligation, potentially saving or costing you thousands per year. In the year you move, you typically file part-year returns in both states. The biggest tax savings come from moving from a high-tax state to a no-income-tax state. A $100,000 earner moving from California to Texas can save over $5,000 annually in state income tax alone.
Filing in the Year of Your Move
Part-Year Resident Returns
Most states require you to file a part-year resident return, reporting income earned while you were a resident:
- Old state: Report income from January 1 through your move date
- New state: Report income from your move date through December 31
Your employer should switch state withholding when you notify them of your new address. If they do not, you may be over-withheld in one state and under-withheld in the other.
When Both States Claim You
Some states are aggressive about residency. If you move from New York to Florida in March but keep a New York apartment, New York may argue you are still a resident. To clearly establish your new domicile:
- Get a new driver's license
- Register to vote in the new state
- Update your address with your employer, bank, and the IRS
- Sell or lease your old home
- Spend the majority of your time in the new state
Real Example With Actual Numbers
Amy earns $120,000 and moves from California to Texas on July 1.
Part-Year California Return (Jan 1 - Jun 30)
- Income earned in CA: $60,000 (half the year)
- California tax on $60,000: ~$2,400
- CA SDI (1.1% on $60K): $660
- California total: ~$3,060
Part-Year Texas Return (Jul 1 - Dec 31)
- Income earned in TX: $60,000
- Texas tax: $0
Full-Year Comparison
| Scenario | Annual State Tax |
|---|---|
| Full year in California | ~$6,300 + ~$1,320 SDI = ~$7,620 |
| Full year in Texas | $0 |
| Moved July 1 | ~$3,060 |
| First-year savings | ~$4,560 |
| Ongoing annual savings | ~$7,620 |
By the second year (full year in Texas), Amy saves the full $7,620. Over 10 years, that is $76,200 in state tax savings. Use the relocation tool to calculate your savings.
Best State Moves for Tax Savings
| From | To | Savings on $100K Income |
|---|---|---|
| California | Texas | ~$5,500/year |
| New York (state) | Florida | ~$5,200/year |
| NYC (state + city) | Florida | ~$9,000/year |
| Oregon | Nevada | ~$7,500/year |
| New Jersey | Florida | ~$4,200/year |
| Minnesota | Texas | ~$5,000/year |
Beyond Income Tax: Other Costs
State tax is just one factor. Consider:
Property Taxes
- Texas has much higher property taxes (1.6%) than California (0.7%)
- A $400,000 home in Texas costs $6,400/year vs $2,800 in California
- This offsets about $3,600 of the income tax savings for homeowners
Sales Tax
- Texas: up to 8.25% combined
- California: up to 10.25% combined
- Florida: up to 7.5% combined
- Oregon: 0%
Cost of Living
Housing costs vary enormously within states. Moving from San Francisco to Austin might save on state tax AND reduce your rent by $1,500/month. Moving from rural New York to Miami might save on state tax but increase housing costs.

Special Considerations
Remote Workers
If you move but keep the same employer, make sure they update your state withholding. Some employers may need to register in your new state before they can pay you there. See remote work tax rules.
State Retirement Income Taxes
If you are approaching retirement, check whether your new state taxes pensions, Social Security, and 401(k)/IRA distributions. Some states exempt all retirement income.
Timing Your Move
Moving in January means you file a part-year return for only a few days in the old state. Moving in December means you spent nearly the whole year in the old state and may not see significant savings until the following year.
