Before You Leave Illinois
File a part-year IL-1040 with Schedule NR
For the year you move, file Form IL-1040 with Schedule NR. Illinois taxes all income you received while you lived here. After you move, it taxes only income from Illinois sources. On Schedule NR, enter the dates you lived in Illinois and in your new state. If your new state also taxed income you earned as an Illinois resident, you may get a credit on Schedule CR.

After you move, keep reporting net income from real estate located in Illinois on Schedule NR. If you sell Illinois real estate, report that gain too. Illinois does not tax a nonresident on nonbusiness gains from intangibles, such as stock.

You can get a homestead exemption only on your main residence. If the house is no longer your main residence, apply to the Cook County Assessor to remove the exemption. The Assessor audits exemptions. If you kept one you were not entitled to, it bills the tax, interest, and penalties. It can also put a lien on the property.

If you sell your vehicle, tell the Secretary of State. Do it at a DMV, or mail the Seller's Report of Sale form. Until the record changes, emissions test notices keep coming to you.

Your new state may ask for proof that your Illinois license is valid. Illinois stopped issuing clearance letters in 1997. Other states check your record through the Problem Driver Pointer System. If your new state still wants written proof, order a copy of your Illinois driving record.

A FOID card can be revoked when the holder no longer lives in Illinois. If yours is revoked for that reason, destroy the card. Follow the firearm laws of your new state.

Get a California driver license within 10 days
You can drive on an out-of-state license for no more than 10 days after you establish residence here. Once you are a resident, you cannot drive for work at all until DMV issues your California license. Plan the DMV visit for your first week.
Source: California Vehicle Code 12505Expect a knowledge test at the counter
A valid license from another state does not transfer automatically. You complete the DL/ID application and visit a field office. There you give your Social Security number, prove your identity and residency, and pay a nonrefundable application fee. The fee stays valid for 12 months. You also get a thumbprint scan and photo, and pass a vision exam and the knowledge test. You get three attempts at each required knowledge test. After that, the application expires and you must reapply. Offices do not start a test within 30 minutes of closing.
Source: California DMV, Driver LicensesRegister the vehicle within 20 days
You have 20 days to apply. The clock starts when you accept a job here or establish residency, whichever comes first. Bring the last out-of-state title and registration certificate, a completed Application for Title or Registration (REG 343), and the out-of-state plates. You also need a Verification of Vehicle (REG 31) signed by an authorized verifier. Gasoline models from 1976 onward need a smog certificate from a California station. So do diesel models from 1998 onward under 14,001 pounds GVWR. If a document is missing, submit the application and fees on time anyway. The penalty is tied to the deadline, not to the missing document.

The state minimums are $30,000 for injury or death to one person, $60,000 for injury or death to more than one person, and $15,000 for property damage. Comprehensive and collision coverage do not count toward the requirement. If DMV never receives proof of insurance for the vehicle, it suspends the registration. The car then cannot legally be driven or parked on a public road until you submit proof.
Source: California DMV, Insurance RequirementsCheck whether you owe use tax on a recently bought vehicle
Use tax applies to a vehicle bought and first used outside the state and brought here within 12 months of purchase. The law presumes you bought it for use here. Any one of several conditions triggers this. Examples are registering the vehicle here in the first 12 months of ownership, or keeping it here for more than half of that period. You can rebut the presumption with documents such as out-of-state registration, insurance records, fuel and lodging receipts, and proof of where you first used it. The use tax rate matches the sales tax rate at the address where you register the vehicle.

If you buy a home and live in it, the state constitution takes $7,000 off its taxable value. File form BOE-266 once with the county assessor. The home must be your principal residence on the January 1 lien date. File by February 15 to get the full exemption for that year.
