Identify what you actually own

A former employer's 401(k), a traditional IRA, and a Roth IRA should not be placed in one undifferentiated retirement category. Collect the account title, plan or custodian details, contribution history where relevant, and recent statements. If you have after-tax basis or a history of conversions, retain the records establishing it rather than expecting a current balance to tell the full story.

Tell the adviser whether the money is still invested, already paying distributions, or scheduled for a change. A rollover, Roth conversion, withdrawal, and transfer of cash after withdrawal are different events. They may look similar on a bank screen while raising different questions. Describing the sequence precisely helps avoid advice intended for a transaction you are not making.

Ask the custodian about living overseas

A brokerage or plan administrator sets its own service policies within the applicable rules. Ask how an Argentine residential address affects account maintenance, investment activity, distributions, and customer support. A familiar app continuing to work is not confirmation that every service remains available. Give accurate address information and distinguish a mailing address from where you actually live.

Establish a way to receive notices and complete authentication from Argentina. Check what happens if your phone is lost or a US number stops receiving messages. Keep official contact details accessible outside the account itself. The tax status of a retirement plan and the practical ability to direct a payment are separate issues; both need to work when you depend on the account for living costs.

US reporting does not end at departure

US citizens generally remain subject to US taxation on worldwide income while abroad, under the applicable filing rules. Retirement distributions keep their own US treatment rather than becoming foreign earned income simply because you receive them in Argentina. The foreign earned income exclusion should not be assumed to shelter pension or retirement-account withdrawals.

Required distributions, withholding, and possible additional taxes depend on account type and personal circumstances. Consult current IRS instructions rather than relying on an age or deadline remembered from an older retirement article. A foreign address does not itself cancel these rules. Make sure the administrator and preparer understand the intended payment schedule before using the net deposit as your available spending figure.

Argentine treatment needs its own analysis

ARCA (formerly AFIP) administers the Argentine side. Tax residence, account structure, and the character of a transaction can affect the analysis of foreign retirement assets and receipts. Do not assume that US tax deferral or qualified Roth treatment automatically carries across the border. Equally, do not infer a definite Argentine liability from the account name alone.

Ask the Argentine adviser what must be disclosed while funds remain inside the account and what changes when money is distributed, converted, or moved. Request the basis for the treatment and the records needed to support it. The correct answer may depend on details not visible on a summary statement. This guide does not assign a universal tax outcome to a 401(k), traditional IRA, or Roth IRA.

Do the cross-border review before moving the money

There is no US–Argentina income tax treaty. A pension article written for Americans in a treaty country may therefore describe protections or residence rules that are unavailable here. Domestic credits or other relief may still be relevant, but their availability and timing require review. One country's tax payment does not automatically erase the other country's entire calculation.

Give both advisers the proposed transaction date and amount before authorizing an irreversible change. Ask whether the countries recognize the event in the same period and how any relevant credit would be documented. Investment suitability is another question again. A rollover that is convenient for account management still deserves tax review, and a tax-driven change still needs to fit your income and risk needs.

Separate the distribution from the transfer to Argentina

The retirement account can distribute money into a US account before you arrange a separate transfer for Argentine expenses. Keep the records for each stage, including withholding, fees, and currency conversion. This makes it easier to distinguish the retirement receipt from the later movement of money you already own. It also helps explain the source of funds if a provider asks.

Foreign-account reporting is separate from the treatment of the US retirement account itself. If a distribution reaches an Argentine account, ask about the reporting rules applicable to that account and your broader holdings. Maintain beneficiary details and a secure document inventory as well. A family member helping during illness should be able to locate the institution and its formal assistance process without sharing or guessing your login.

The account may remain in the United States while the decisions around it become cross-border. Keep those decisions deliberate: verify the custodian's rules, understand the proposed transaction in both countries, and retain the evidence before the balance changes.

Questions worth checking

Is my Roth IRA automatically tax-free in Argentina?

Do not assume US Roth treatment is recognized identically in Argentina. Have an Argentine adviser review the account and planned transactions in light of your tax residence.

Does living abroad remove US retirement withdrawal rules?

No. Account-specific distribution, withholding, and reporting rules continue to require attention. Use current IRS guidance for your circumstances rather than an outdated age or deadline.

Can the foreign earned income exclusion cover IRA withdrawals?

Retirement distributions are not foreign earned income merely because you receive them abroad. Ask your preparer about the rules for the actual income type.

Should I roll over my 401(k) before moving?

There is no universal recommendation. Review custodian policies, investment needs, and both countries' treatment before making the change, especially around a change in tax residence.
