What This Move Means for You
Lower cost of living
Montana is about 25% cheaper than California overall, so your budget should stretch noticeably further — especially on housing.
Lower income tax
Montana's top income tax rate (~5.65%) is lower than California's (~13.3%), leaving a little more in each paycheck.
Colder winters ahead
Montana averages 16°F cooler than California. Pack cold-weather clothing and expect higher heating bills through the winter.
Before You Leave California
Report the address change to DMV within 10 days
The 10-day deadline applies whether or not the car moves with you. It covers your license, vehicle, and vessel records. If a registration renewal notice reaches you after the move, do not ignore it. On the back of the stub, write the date the vehicle left the state and the state where it is now registered. Mail it in to close the record.
Source: California DMV, Moving Out of StateYour last return is Form 540NR, not Form 540
A part-year resident was a resident for part of the year and a nonresident for the rest. For the year of the move, you file Form 540NR. The filing thresholds use the same gross income and adjusted gross income tables as for full-year residents. You may still have to file even below them.

Residency depends on where your closest connections are. The Franchise Tax Board looks at where your family lives, where you keep bank accounts, where your doctors and attorneys are, where you own real property, and how permanent your work here was. In its own example, a taxpayer declared residency in another state and moved the bank accounts. That taxpayer was still a resident, because the home, the social ties, and most of the year stayed here. A separate safe harbor covers people who leave under an employment contract. It requires an uninterrupted absence of at least 546 days. It does not apply if intangible income tops $200,000 in a covered year, or if the main purpose of leaving was to avoid the tax.

The exemption stays on the roll until someone removes it, and the claimant must report that they no longer qualify. December 10 is the last day to end it without a penalty. Even if you move early in the year, send the notice before that date.
