Moving to Guam

Every US move

These are the steps that prove a move in any state: a new main home, your family, your address, your voter registration, your day-to-day providers and your records. State and territory lists add their own steps.

Arriving in Guam

On Guam, a bona fide resident files one return with the Department of Revenue and Taxation instead of with the IRS, so the residence tests decide who you file with. The required admin is the Guam license within 90 days and vehicle registration.

Before you move

First 90 days

  • Get a Guam driver's license within 90 days of arriving

    Required

    Applies if you drive

    Deadline: Within 90 days of arriving on Guam (extendable up to 1 year by registering your out-of-Guam license)

    Under 16 GCA sec. 3101(d), a valid license from another US state, territory or commonwealth lets you drive on Guam for up to 90 days from arrival. After that you must hold a Guam license; you are exempt from the written test and the demonstration test, and you surrender the old license unless DRT has adopted other procedures. The 90 days can be extended to the earlier of 1 year from arrival or your old license's expiry if you register the license with DRT and pay a fee of up to $25. Active-duty military and their dependents are exempt. DRT takes appointments at myid.guam.gov. DRT's Real ID policy page asks for originals of proof of identity, date of birth, US citizenship or lawful status, Social Security number, and residency: two documents showing your name and residential address, or a mayor's letter or military housing verification dated within the last 30 days and addressed to DRT.

    Keep as proof: Copy of the Guam license and DRT receipt; the Certificate of Registration if you extended

  • Register your vehicle with the Guam DRT

    Required

    Applies if you own a vehicle

    Guam requires every motor vehicle driven on a highway to be registered unless exempted (16 GCA sec. 7101-7102). The vehicle must be on Guam when you apply for original registration (sec. 7107). For a vehicle registered elsewhere, your application states where and when it was last registered, and you surrender the unexpired out-of-Guam plates and registration papers to DRT, which returns the plates to the issuing state or territory (sec. 7108). DRT refers an original application to the Guam Police Department for an inspection before it registers the vehicle (sec. 7106). A special permit from the Chief of Police lets you move a vehicle not previously registered from the port to your home or the place of registration (sec. 7103). The sections reviewed give no deadline for a new resident to register.

    Keep as proof: Guam registration and plate paperwork

  • Move your voter registration to Guam

    Applies if you are a registered voter

    Where you vote is a closer-connection factor in Pub. 570, and being registered to vote in a US political subdivision counts as a 'significant connection' to the US under Treas. Reg. 1.937-1(c)(5). Cancel your old state registration and register with Guam's election office if you are eligible.

    Keep as proof: Confirmation of the cancelled state registration and the new Guam registration

Leaving Guam

Every US move

These are the steps that end your ties to the place you are leaving: the old home, your belongings, your mail, your voter registration and your memberships. States weigh the strength of your ties, so keep a record of the move. The old state's list covers its own rules.

Before you move

Move week

  • Move your treasured belongings to the new home

    New York's guidelines treat the location of items you hold near and dear (family heirlooms, art, collections, photo albums, pets) as a primary factor, and note that a mover's bill of lading or an insurance statement can document the move. Items left behind in the old state can suggest you have not given it up.

    Keep as proof: Mover's bill of lading or inventory, and an insurance policy showing the new address

  • Forward your mail before you leave

    File a permanent change of address at the Official USPS Change of Address site (identity verification required) or at a Post Office. USPS says to allow at least 7 to 10 business days after approval for it to start, so file before moving day.

    Keep as proof: USPS confirmation email

Leaving Guam

Leaving Guam, check the year-of-move rules before deciding whether Guam or the IRS gets your return.

Before you move

Move week

  • Send your Guam plates to DRT when you sell a vehicle

    Required

    Applies if you own a vehicle

    Deadline: When you transfer the vehicle; the new owner has 10 days to register it

    Under 16 GCA sec. 7146, a Guam vehicle registration expires when the owner transfers the title or any interest. The owner must remove the plates and forward them to DRT, or have the plate number assigned to another vehicle. The new owner may drive the vehicle for 10 days after the transfer and must register it within 10 days. The owner and buyer endorse the certificate of ownership (sec. 7144).

    Keep as proof: Endorsed certificate of ownership and DRT receipt for the plates
