Virtual mailbox for expats: keeping a U.S. address the right way
Updated October 28, 2026 · 31 CFR 1020.220, IRS instructions and Publication 54, FVAP, California FTB, USPS DMM 508 and provider pricing pages checked on that date unless a row shows its own date · Affiliate disclosure
If you move abroad, you'll probably still get U.S. mail: bank and brokerage letters, IRS notices, card replacements, jury or DMV mail. A U.S. virtual mailbox gives that mail a home and lets you read scans of it from overseas. But a mailbox only works in the right fields. Banks, the IRS, your election office and your old state each ask a different address question. This guide quotes what each one actually says.
Short answer (checked October 28, 2026)
📬 Good fit: a U.S. mailing address for statements, IRS letters and packages. The IRS also accepts a foreign address on your return, and Form 8822 changes it.
🏦 Not a residential address at a bank: the federal CIP rule asks for a residential or business street address. If you have neither, it allows an APO/FPO box or a relative's or contact's street address. A virtual mailbox isn't on that list.
🗳️ Voting: overseas, your voting residence is the state where you last lived before leaving, not your mailbox's state (FVAP).
🧾 State tax: a mailbox in your old state can be one more tie to it. California, for example, treats someone domiciled there who is away "for a temporary or transitory purpose" as a resident.
Which address fields an expat has to fill
U.S. mailing address
Virtual mailbox fits. Mail is received at a USPS-registered CMRA and held, scanned or remailed (USPS DMM 508.1.8). Where a form asks only where to send mail, this is what it's for.
Bank residential address
Street address expected. 31 CFR 1020.220 asks banks to collect a residential or business street address. Many banks accept a foreign street address, but the bank decides. See the bank account guide.
IRS address
Foreign or U.S. mailing address. Form 1040 has foreign country, province and postal code fields. Form 8822 updates your address.
Voting residence
Your last U.S. home address. FVAP says it's the state where you last lived before leaving, even if you no longer have ties there.
State tax domicile
Facts and intent, not mail. State rules differ. A mailbox in your old state is not a way to leave or keep that state's tax residency.
PS Form 1583
Your own home address. The mailbox application asks for your permanent residential or business address and an ID that proves it. See below.
Keeping U.S. bank accounts: the CIP rule
Every U.S. bank runs a Customer Identification Program under 31 CFR 1020.220. For an individual, the address the bank must collect is:
"(i) For an individual, a residential or business street address; (ii) For an individual who does not have a residential or business street address, an Army Post Office (APO) or Fleet Post Office (FPO) box number, or the residential or business street address of next of kin or of another contact individual"
Three things follow from that text. First, the rule asks for a street address. It doesn't say the street address must be in the United States, but whether a given bank accepts a foreign one is that bank's policy. Second, a virtual mailbox isn't one of the fallback options; a next-of-kin or contact person's street address is. Third, a bank can still let you add your virtual mailbox as a separate mailing address. Mercury, for example, rejects virtual addresses for its physical address field but has a separate mailing address (see the table below). For bank-by-bank rules, see the virtual mailbox for bank account guide.
IRS: foreign address, Form 8822 and the 2-month extension
Foreign address on your return. The Form 1040 instructions say: "If you have a foreign address, enter the city name on the appropriate line. Don't enter any other information on that line, but do complete the spaces below that line (Foreign country name, Foreign province/state/county, and Foreign postal code). Don't abbreviate the country name."
P.O. boxes. The same instructions say to enter a box number "only if your post office doesn't deliver mail to your home." They don't mention CMRAs or virtual mailboxes either way.
Changing your address. "If you plan to move after filing your return, use Form 8822 to notify the IRS of your new address." Form 8822 has foreign country, province and postal code fields for both old and new addresses.
Extra time to file. Publication 54 says U.S. citizens and resident aliens get "an automatic 2-month extension to file your income tax return and pay federal income tax" if, on the regular due date, they are "living outside the United States and Puerto Rico" and their main place of business or post of duty is outside the U.S. and Puerto Rico. (Interest still applies to unpaid tax; see Pub. 54.)
Withholding because of a foreign address. Publication 54 notes that if 30% tax is withheld in error from a U.S. citizen or resident alien "because you have a foreign address, you should notify the payer of the income to stop the withholding. Use Form W-9 to notify the payer."
Voting and state residency caveats
Voting. The Federal Voting Assistance Program says: "Your voting residence is the State in which you last resided immediately prior to your departure from the United States." That stays valid even if you no longer own property there, your intent to return is uncertain, or the old address is no longer a recognized residential address. Your mailbox's state doesn't change it.
State taxes. FVAP also says voting in federal elections "may not be used as the sole basis to determine residency for the purpose of imposing State and local taxes," but that if you have other ties to the state, "you may be liable for State and local taxation, depending on that particular State law." California is one example of why this matters. Its Franchise Tax Board says you're a California resident if you're present in California for other than a temporary or transitory purpose, or "domiciled in California, but outside California for a temporary or transitory purpose" (details in FTB Publication 1031). We haven't sourced other states. Ask a tax professional before you keep or drop ties to your old state.
Setting up the mailbox from abroad (Form 1583)
Every U.S. virtual mailbox needs a USPS PS Form 1583 on file, with two IDs. Our Form 1583 explainer lists the IDs USPS accepts under DMM 608.10: a foreign passport is on the primary photo ID list, and the secondary ID must prove the permanent residential or business address you put on the form. The CMRA must keep each customer's Form 1583 current in the USPS CMRA Customer Registration Database, and "any expired, illegible, or unclear identification or address documents" count as non-compliant (DMM 508.1.8). If you're abroad, check how your provider handles remote notarization or verification before you sign up. iPostal1, for example, says on its RV page that it offers an online notary for $25.

Mercury Bank / fintech
Legal address, physical (day-to-day) address, beneficial owner home address (mailing/card address is separate)
Accepted in some fields only
Mercury's Company address requirements article says the physical address (where you and your team work day-to-day) cannot be a P.O. box, virtual address, commercial mail receiving agency, mail center or registered agent address. Its legal-address article says P.O. boxes and virtual offices/workspaces are not accepted as the legal address, and its eligibility article says registered agent addresses, P.O. boxes and UPS Store addresses are not accepted for the principal place of business. Each beneficial owner's home address cannot be a PO box, mail drop, or commercial mail-receiving or virtual address service. The mailing address (where physical cards are sent) must be a physical, USPS-deliverable address; Mercury's help pages do not name CMRAs for that field.
“We don't accept a P.O. box, virtual address, commercial mail receiving agency, mail center, or registered agent address.”
Federal bank CIP rule: individual address (31 CFR 1020.220) Regulation
Personal address a bank must collect
Physical address required (CMRA not named)
For an individual customer, a U.S. bank's Customer Identification Program must collect a residential or business street address. Only if the person has neither may the bank take an APO/FPO box or the street address of next of kin or another contact individual. A virtual mailbox is not on that list, which is why banks ask expats and full-time travelers for a street address in addition to any mailing address.
“For an individual who does not have a residential or business street address, an Army Post Office (APO) or Fleet Post Office (FPO) box number, or the residential or business street address of next of kin or of another contact individual”
IRS (Form 1040 address & Form 8822) Federal agency
Individual tax return mailing address
No restriction stated
The Form 1040 instructions tell filers with a foreign address to fill in the foreign country, province and postal code fields, and to enter a P.O. box only if the post office doesn't deliver mail to their home. They say to use Form 8822 to notify the IRS of a new address. They don't mention CMRAs or virtual mailboxes either way.
“If you have a foreign address, enter the city name on the appropriate line. Don't enter any other information on that line, but do complete the spaces below that line”
FVAP (overseas citizen voting residence) Federal agency
Voting residence for overseas citizens
Physical address required (CMRA not named)
The Federal Voting Assistance Program says an overseas U.S. citizen's voting residence is the state where they last resided immediately before leaving the U.S., even if they no longer own property there or their old address is no longer a recognized residential address. It also says voting for federal offices can't be the sole basis for state tax residency, but other ties may create state tax liability.
“Your voting residence is the State in which you last resided immediately prior to your departure from the United States.”

Homepage states 'Plans from $9.99 per month' and its FAQ says the cheapest plans are $4.99 and some vanity addresses cost up to $50. Its own FAQ says it does not recommend using the address as an official business address for LLC registration, IRS or banking without checking with the state/institution first.
Scanning matters more than forwarding. International postage is expensive, so look at how much content scanning costs per item and how many scans are included.
Pick the state on purpose. Your mailbox doesn't set your voting residence, but a mailbox in your former state is another tie to it. If you're trying to end state residency, talk to a tax adviser before you choose.
Check international shipping. Use each provider's shipping calculator. iPostal1 lists discounted international forwarding locations, and Earth Class Mail (LegalZoom Virtual Mail) lists international forwarding at $5 per shipment plus postage and $1 per item.
Check deposits. If you still get paper checks, compare check deposit fees (in the cards above).
Keep the ID current. Expired passports make your Form 1583 non-compliant, so update your provider when you renew.
Checklist
Before you leave, list every U.S. institution that mails you: banks, brokers, IRS, state tax agency, Social Security, insurers, DMV.
Ask each bank what address it needs from a customer living abroad, and add the mailbox as a mailing address only where allowed.
Open the mailbox and complete PS Form 1583 (passport plus an address ID). See Form 1583 explained.
File Form 8822 with the IRS (foreign or mailbox address), and file a USPS change of address from your old home.
Note your voting residence (your last U.S. address) and register to vote absentee from abroad through FVAP.
Get advice on your old state's residency rules before you keep a home, car registration or mailbox there.
Set a reminder to upload your renewed passport to your mailbox provider.
Frequently asked questions
Can I keep my U.S. bank account with a virtual mailbox address after moving abroad?
As a mailing address, often yes, but not as your residential address. The federal CIP rule (31 CFR 1020.220) asks banks to collect a residential or business street address for individuals, and if you have neither, an APO/FPO box or the street address of next of kin or another contact person. Whether a bank accepts a foreign street address is that bank's policy.
What address should I put on my tax return if I live abroad?
The Form 1040 instructions let you enter a foreign address using the foreign country, province and postal code fields. They say to use a P.O. box only if the post office doesn't deliver mail to your home, and to file Form 8822 if you move after filing. They don't mention virtual mailboxes either way.
Do expats get extra time to file U.S. taxes?
IRS Publication 54 gives U.S. citizens and resident aliens an automatic 2-month extension to file and pay if, on the regular due date, they live outside the United States and Puerto Rico and their main place of business or post of duty is outside the United States and Puerto Rico. Interest still runs on tax not paid by the regular due date.
Does a virtual mailbox change my voting residence?
No. The Federal Voting Assistance Program says an overseas citizen's voting residence is the state where they last resided immediately before leaving the United States, even if they no longer have property or other ties there.
Can a virtual mailbox in my old state keep me a state tax resident?
It can be one more tie to that state. FVAP notes that other ties beyond voting may make you liable for state and local taxes depending on state law, and California treats someone domiciled there but away for a temporary or transitory purpose as a resident. Get advice for your specific state.
Can I sign USPS Form 1583 with a foreign passport?
A foreign passport is on USPS's list of acceptable primary photo IDs under DMM 608.10. You also need a secondary ID proving the permanent address you list on the form. Our Form 1583 guide lists every accepted document.
Which virtual mailbox is best for expats?
Compare content scanning costs and international forwarding first, since postage abroad is expensive. Traveling Mailbox, iPostal1, Anytime Mailbox and PostScan Mail all market to expats on their own sites; our comparison table shows their dated entry prices and scanning fees.
