Taxes
Illinois has a flat 4.95% income tax (tax year 2026). Illinois generally does not tax retirement income such as Social Security and qualified pension distributions. Property taxes are set locally, and homeowners may qualify for a general homestead exemption, with additional exemptions for seniors. See the Illinois revenue department for current rules.
California's top marginal rate is 13.3% (tax year 2026). Illinois's published rate is lower, but brackets, deductions, credits and any local income taxes differ, so the real difference depends on income and situation. A CPA can run the numbers both ways.
Moving out of California generally doesn't take the sale of a California home out of California's tax reach. Our guide to selling your LA home and moving out of state covers withholding at closing, the capital gains exclusion and the questions to bring to a CPA.
What to check before you go
- Property tax. Rates and assessments are set locally in Illinois, and many places offer an exemption or credit on a primary residence. Look up the specific address with the county or local assessor before you budget.
- Homeowners insurance. Premiums depend on the address, the home and the coverage. Get quotes on a specific property early, before you commit to a purchase.
- Vehicle registration and license. New residents generally have a limited window to register a car and get a driver's license in Illinois. Check the deadline with the state motor vehicle agency.
- Your last California tax year. The year you move usually means a part-year California return, and the sale of a California home can still be taxed by California. Bring the dates to a CPA.
The full list, in the order people usually tackle it, is in our moving out of California checklist.
