Other Legal Things to Check If You're Moving to New York

Before you move to New York, you need a plan to handle all your legal paperwork. That includes residency, insurance, and taxes. It also extends to common practices, like many buildings in New York City requiring certificates of insurance (COIs) for your movers to help.
In New York, you're considered a resident after 90 days, which means the clock starts ticking as soon as you arrive.
New York Driver's License and Car Registration
You have 30 days from becoming a resident in New York to update your driver's license. As long as your out-of-state license meets the requirements, it should transfer smoothly.
According to the New York DMV, your out-of-state license must:
- Have your photograph
- Be valid or less than 24 months expired
- Have been issued at least 6 months before applying for a New York license
Some states don't include an issue date on their licenses, which can complicate things. You'll need a certified driver's license record or a letter from the issuing state that confirms when your license was issued.
If you can't get that letter, you have to start the process all over as if you're getting your first one. That means retaking and passing the knowledge and road tests.
Registering your car in New York follows the same process as registering and titling a new car. Again, you have 30 days to register your vehicle after becoming a resident.
Submit a completed Vehicle Registration/Title Application, along with an original copy of proof of ownership. You also must provide proof of valid New York auto liability insurance and proof of your identity and age. Expect to pay taxes, including potential sales tax (or proof you've already paid it in your original state) and county use tax.
After your application is processed, you get updated registration documents and vehicle plates.
Voting and Taxes
If you plan on voting anytime soon, you need to update your registration. To qualify for voter registration in New York, you have to be a resident for at least 30 days and meet the same standards as you would in other states. Registered voters can't be in prison for a felony, deemed mentally incompetent by a court, or claim the right to vote anywhere else.
You can register online as long as you have a valid New York state driver's license, permit, or ID card and your ZIP code is currently on record with the DMV. You also need to verify your Social Security number (SSN).
Once you become a resident of New York, you start paying state taxes. While a handful of states don't impose income taxes, New York does.
If you live in New York City or Yonkers, you have to file city income taxes as well, so keep that in mind. If you're unsure about how you'll be taxed, seek guidance from a local tax professional. They know the laws and can help you avoid getting hit with financial penalties later.
