A lot of people planning an international relocation plan for the normal things. Everyone plans for visas, moving, etc. Very few plan for the thing that usually creates the most headaches in the beginning; this being the address they use on their brokerage account.
The problem usually appears at the worst time. You try to get into your account to rebalance it or sell something in it and find out that it is locked. There may have even been a message asking for verification of your address. Sometimes by the time you figure out what happened, the sale has already occurred. In virtually every case (of course I'm sure there's always one) it wasn't the trade. It was the address.
When you own U.S. investment accounts from outside of the United States, the address you put in when you open your brokerage account is a financial decision as well as just administrative work. Below are five options you can consider, along with their performance characteristics.
Why Brokers Care About Your Home Address
U.S. banks were required to develop a Customer Identification Program under the USA PATRIOT Act. Part of that requirement is obtaining and verifying a physical residential street address for every client. A residential address is defined as such, not a mailing address.
Brokers collect and verify addresses through various methods, but most rely on existing databases of commercial addresses. That matters because of a piece of postal classification most investors are unfamiliar with.
Mailbox services require completion of USPS Form 1583 when you register. That document serves two purposes. First, it provides authorization for the service provider to receive mail addressed to you. Second, it designates the address within postal data as a Commercial Mail Receiving Agency, or CMRA. So when a broker verifies your address and it returns as a CMRA, the system recognizes it as a commercial mail drop where a residential address should be. Broker policies range widely and can change over time, which is why establishing the right address before relocating is preferable to trying to fix it afterwards.
Underneath that sits a second concern. The address you give your bank, your broker and your state revenue department is a strong indicator of your domicile, and domicile determines whether you continue to owe state income tax on worldwide income while living internationally. States including California, New York and New Jersey tend to hold on to domicile very closely.
With that in mind, here are the five available choices.
1. Using a Family Member’s Address
What it is: a legitimate residential street address obtained by using a parent, sibling or friend’s home as your address of record.
Where it holds: it is completely free. It is a genuine residential address, and it will pass a CMRA check because it is not one. Many people will find this is the best solution, and it is worth saying so plainly before spending money on any of the alternatives.
Where it fails: its success depends on another person staying put, remaining willing, and telling you when items arrive. Time-sensitive mail is the usual failure point, because a tax notice sitting on a kitchen counter for three weeks is a real cost. There is also the potential for creating the wrong impression about your domicile if that address sits in a high-tax state you were trying to leave.
Best for: people with a stable family base in a state they are content to be associated with.
2. Virtual Mailboxes (Digital Mailboxes)
What it is: a service that receives your mail at their physical address, scans the envelopes, and gives you access to the images through an application. Well-known providers include US Global Mail, Traveling Mailbox, iPostal1 and Anytime Mailbox. Of those, iPostal1 and Anytime Mailbox each operate some of the largest networks of physical locations available.
Where it holds: as far as mail processing is concerned, these services are very good and relatively inexpensive. Their scanning capabilities are quick. Their forwarding capabilities are flexible. The better quality providers will bundle packages together, and they will even deposit checks into your checking account. If your primary issue is receiving your mail while abroad, this is the least expensive viable option and the other four options on this list would be overkill.
Where it fails: classification as a CMRA. This does not make the service illegitimate, but it does mean the address may be flagged during a broker’s review, and state motor vehicle agencies typically will not recognize it as proof of residency for a license. If you are using the service simply to receive mail, neither issue is relevant. If you intend to use the address as your address of record on financial accounts, either could create a problem.
Best for: managing your mail, not establishing identity.
3. Maintaining Property Ownership
What it is: you keep ownership of a property, such as a house or condominium, and continue to use it as your address.
Where it holds: using a property you own creates the most robust proof of a U.S. residential connection. Nothing surpasses a deed and a utility bill in your own name.
Where it fails: cost, obviously. Beyond that, many people fail to realize that maintaining property in a high-tax state creates a particularly hard-to-break tie when an auditor is deciding whether you truly relocated.
In the 2025 New York Tax Appeals Tribunal decision in Matter of Hoff, although a couple had registered as voters in Florida and had obtained Florida driver's licenses and filed a Declaration of Domicile in Florida, they were still assessed nearly $60,000. The reason was that they maintained both a residence and business in NY and stayed in Florida fewer days each year than in NY. Although their paperwork indicated domicile in Florida, the evidence behind it simply wasn't enough.
Best for: people who want to retain the property for reasons unrelated to establishing an address.
4. A Residential Address With a Lease and Utility Accounts
What it is: an actual dwelling where you hold a lease and utility account in your own name, provided as a service. Your Tax Base provides this type of service to fill the gap the other options leave.
Where it holds: it is residential rather than commercial in postal data, and the supporting documents are the ones institutions ask for when they want proof rather than an address on a form. A lease and utility bills in your name are what a bank, a broker or a DMV will actually accept. Pairing it with a state that has no income tax addresses the domicile problem at the same time, which is why Florida is the common choice.
Where it fails: it costs more than a mailbox, and it is unnecessary if all you need is mail scanning. It also only works if the underlying move is real. Documents corroborate a genuine change of domicile. They do not manufacture one, and anyone selling it as a way to claim a state you have no connection to is selling you an audit.
Best for: people whose financial accounts, license or state tax position depend on the address holding up.
5. Using a Professional’s Business Address as Your Primary Contact Address
What it is: using a professional’s business address as your contact address of record.
Where it works: it may be useful for receiving official communications. A formally appointed daily money manager or adviser can handle time-sensitive matters properly.
Where it fails: it is a commercial address, so it runs into the same classification issue as option two. It also places another person between you and your mail.
Best for: limited circumstances where a professional already manages your affairs.
What to Verify Before Committing
Three questions. Get the answers in writing.
-
Is the address classified as residential or as a CMRA? Ask directly. Any provider who cannot clearly answer this has given you your answer.
-
Can you provide me with a lease and a utility bill in my name? If not, the address will not meet the requirements of any request for verification of residency.
-
Will my broker accept this as a valid address? Policies vary by firm, so consult your own custodian rather than relying on a general claim.
The Component That Costs More Than the Limitation Imposed by the Account
A frozen brokerage account is an inconvenience that can usually be resolved with a telephone conversation and the submission of some documentation. The risk of a significant state tax liability resulting from domicile misclassification is much greater, because the silent compounding of additional years of tax liability increases until you discover it during an audit.
Residency and domicile are two distinct legal statuses. Residency is primarily about the number of days spent in a particular jurisdiction. Domicile is your single permanent legal home, and it does not change simply because you left. It changes once you establish a new permanent home and demonstrate abandonment of the previous one.
Although the Foreign Earned Income Exclusion might seem like it could assist in this area, state laws do not follow this format.

Determine the validity of your mailing address prior to departing. It belongs in the same planning pass as building an investment budget that balances saving and investing. Correctly establishing a mailing address is likely the least costly item on your checklist, but may prove to be the most costly if done incorrectly.
