Voter Registration
Voter Registration
Registering to vote after moving is one of the simplest updates you’ll make during the relocation process. Unlike other services, you do not need to cancel your old voter registration. Once you register at your new address, your previous registration automatically becomes inactive.
If you’ve registered to vote before, the process will feel familiar, the only difference is that you’ll be registering in a new state.

You must be at least 18 years old to register.
Registration methods vary by state. Depending on where you move, you may be able to register online, by mail, or in person. To find out which options your state offers, visit vote.gov and select your new state.
Complete your state’s voter registration form and submit it before the deadline. Deadlines vary widely by state; to check them, visit vote.org for a full list.
After you register, you can verify that everything processed correctly by checking your voter registration status online through your state’s election website.
State Taxes & Residency Requirements
State Taxes & Residency Requirements
Understanding state taxes and residency requirements is a foundational step in navigating the tax implications of an interstate move. These rules determine which state has the right to tax your income and how to file correctly when transitioning from one state to another.
Establishing Residency in Your New State
Establishing Residency in Your New State
Before you can correctly file taxes in a new state, you must establish residency there. This includes both physical presence (actually living in the state) and intent (showing that this is now your permanent home).
Steps that help establish residency include:
Tracking the exact date(s) of your move and when your address officially changes
Keeping a log of how many days you spend in your old state vs. your new state
Changing your mailing address (covered in Phase 3.1)
Updating your driver’s license and vehicle registration (covered in Phase 3.3)
Registering to vote in your new state
Opening and using bank accounts in your new state, and closing old-state accounts
Buying or leasing a residence in the new state, and selling or renting out your former home
Updating addresses on important documents such as insurance, passports, wills, and other legal records
The more steps you take to establish residency, the harder it is for your old state to argue that you are still a resident for tax purposes.
Understanding How Your State Taxes Will Change
Understanding How Your State Taxes Will Change
Every state follows different tax rules, and your tax obligations depend on whether your old and new states collect state income tax. These are the four possible scenarios:
Old state has state income tax → new state has state income tax
You will file part-year state income tax returns in both states.
Each state only taxes the income earned while you lived there.Old state does NOT have state income tax → new state DOES have state income tax
You will file one part-year tax return for your new state.
Nothing is required for your old state.Old state does NOT have state income tax → new state does NOT have state income tax
You do not need to file any state income tax returns.
(But you still must establish residency for legal and tax purposes.)Old state DOES have state income tax → new state does NOT have state income tax
You will file one part-year tax return for your old state.
Nothing is required for your new state in terms of state income tax.
How Part-Year Taxes Work
How Part-Year Taxes Work
When filing part-year returns, you report only the income earned while living in each state.
Your W-2 forms, employer payroll records, and dates of residency will help you determine what income belongs to which state.
It may also be necessary to update your state tax withholding with your employer so the correct state is receiving taxes after your move.
Other Important Considerations
Other Important Considerations
Property tax laws differ significantly between states and even between counties or cities.
Make sure you understand:
New rates
Exemptions
Deadlines
How your property should be assessed
Estate and inheritance laws vary from state to state.
Your will, trust, power of attorney, and medical directives may need updates.
It is recommended to have documents reviewed by an attorney licensed in your new state.
By taking the necessary steps to establish residency and understanding how to file taxes correctly, you can avoid:
Accidental tax fraud
Double taxation (two states claiming you owe them)
Legal or financial penalties
Establishing clear residency protects you and ensures you are only taxed by the state that legally has the right to tax you.
