FBAR joint filing for married couples: rules, Form 114a, and joint accounts

FinCEN Form 114, better known as the FBAR, requires US persons to report their foreign financial accounts to the Treasury each year.

If you are married, one thing to get straight early: your Form 1040 filing status – MFJ or MFS – has no bearing on the FBAR threshold, who must file, or how accounts get reported.

The FBAR is a FinCEN report, not an IRS tax return. FBAR rules come from the Treasury’s Bank Secrecy Act framework, administered by FinCEN – with the IRS playing a major role in compliance and enforcement.

Spouses may use one FBAR only when the narrow spouse exception applies. When it does not, each spouse files separately and reports every joint account at its full maximum value – not a 50/50 split.

At a glance:

• One spouse can file on behalf of both only with written authorization on Form 114a, and only when every reportable account of the non-filing spouse is jointly owned with the filing spouse.
• Each spouse still reports their own separately held accounts on their own FBAR.
• Joint accounts are reported at 100% of the maximum balance by each filer – the duplication is by design.
• The FBAR threshold is $10,000 in aggregate across all foreign financial accounts at any point during the year. This threshold applies the same way regardless of marital or filing status.

Does “Married filing jointly” change FBAR requirements?

No. Married filing jointly is an IRS income-tax filing status that applies to your Form 1040. FBAR for married filing jointly is a separate matter entirely – the FBAR is a FinCEN report, and the two systems operate on different rules.

The FBAR threshold for married couples is the same as for anyone else: $10,000 in aggregate maximum value across all reportable foreign financial accounts. There is no higher limit because you are married, no combined threshold for spouses, and no exemption based on how you filed your taxes.

If the aggregate maximum value of your foreign accounts exceeded $10,000 at any point during 2025, you have an FBAR filing obligation regardless of your Form 1040 status.

The following table shows how the two systems differ:

 

US citizens married to nonresident alien spouses face a separate set of filing status decisions on their Form 1040 – but none of those choices affect FBAR.

What counts as a joint account for FBAR purposes?

A joint account for FBAR purposes is any foreign financial account with more than one owner listed on the account documentation at the financial institution. Legal account ownership determines whether the spouse exception can apply – not who deposited the money or who uses the account day to day.

The distinction between joint ownership and mere signature authority matters here. Signature authority means you can direct the bank to move funds, but you are not an owner of record. Joint ownership means both names appear on the account as holders.

Common foreign accounts that may be jointly held:

• Checking and savings accounts at a foreign bank
• Brokerage and investment accounts
• Term deposits and certificates of deposit
• Cash-value life insurance policies at foreign institutions
• Fintech accounts at foreign-located entities, such as Wise or Revolut

Joint owner or signatory?

 

The $10,000 threshold is based on the aggregate maximum value of all your reportable foreign financial accounts – including accounts where you hold only signature authority.

Once the aggregate exceeds $10,000, every reportable account must appear on the FBAR, regardless of its individual balance.

Review your bank account titles and account agreements to confirm whether both spouses are listed as owners or whether one spouse has only signing rights.

When can spouses file one FBAR together? (the spouse “joint filing” exception)

Filing an FBAR jointly is possible, but only under a narrow set of conditions. FinCEN allows spouses to consolidate their FBAR obligations into a single filing when all three of the following are true:

1. All the foreign financial accounts that the non-filing spouse is required to report are jointly owned with the filing spouse.
2. The filing spouse reports the jointly owned accounts on a timely filed FBAR, electronically signed.
3. Both spouses have completed and signed Form 114a, Record of Authorization to Electronically File FBARs, and keep it on file. Form 114a is never submitted to FinCEN – it must be produced only if requested.

If even one of those conditions is not met, each spouse must file separately.

The exception only matters when the non-filing spouse has their own FBAR obligation – meaning they are a US person. A non-US citizen spouse who is not a green card holder or resident alien generally has no FBAR requirement in the first place, so the exception does not come into play.

The FBAR requirements for married filing jointly do not change these conditions in any way. Your Form 1040 status – MFJ, MFS, or any other – has no effect on whether you qualify for the spouse exception.

Who can and cannot use the spouse exception:

 

When the conditions are satisfied, one spouse e-files the FBAR through the BSA E-Filing System and signs using their PIN. That filing covers both spouses. The other spouse does not file separately.

When you cannot file jointly (and must file two FBARs)

The spouse exception does not fit every situation. The following triggers each require separate filings:

• One spouse holds an individually owned foreign account. That spouse must file their own FBAR. The other spouse may still be covered by the exception if all of their reportable accounts are jointly owned with the filing spouse.
• Form 114a was not completed or signed. Without the authorization form on file, a joint filing is not valid.
• Late or amended filings. FinCEN’s joint filing exception applies to timely, original filings. If you are filing late or amending, each spouse generally files their own FBAR.
• Non-spouse joint owners. Parents, siblings, or business partners cannot use the spouse exception. There is no joint FBAR filing option for anyone other than married spouses.

When both spouses file separately, each one reports the full maximum balance of any joint account – not a 50/50 split, regardless of the number of owners. FinCEN wants complete visibility over every account, and each owner is independently responsible for accurate reporting.

FBAR deadline and late-filing consequences for spouses

The FBAR for tax year 2025 is due April 15, 2026, with an automatic extension to October 15, 2026. No form or request is needed for the extension – it applies to every FBAR filer. Filing any time before October 15 is timely and carries no penalty.

Each spouse who must file separately is independently responsible for meeting the deadline. One spouse’s timely filing does not cover the other.

The FBAR limit for married filing jointly is the same $10,000 aggregate threshold that applies to all filers. If either spouse independently crosses that threshold, they have their own filing obligation and their own deadline.

FBAR deadline timeline for tax year 2025:

 

If you missed both deadlines, the following paths may be available depending on your situation:

• Only FBAR missed, all income reported. File the delinquent FBAR through the BSA E-Filing System with a statement explaining the reason for the late filing. As of July 2026, the IRS no longer publishes a no-penalty assurance for delinquent FBARs – penalty relief now depends on reasonable cause. See our guide to delinquent FBAR submission for the current options.
• Returns and FBARs both missed, non-willful. The Streamlined Filing Compliance Procedures let non-willful filers submit three years of returns and six years of FBARs. The foreign offshore track generally eliminates all penalties.
• Willfulness concern or prior IRS contact. Streamlined is generally unavailable. The IRS Criminal Investigation Voluntary Disclosure Practice may apply.
• Filed but inaccurate. File a corrected FinCEN Form 114 with the “amended” box checked, and the original BSA tracking ID entered.

How to report a joint account on FBAR (report 100% of max balance)

The FBAR is an information report, not a tax return. FinCEN’s goal is visibility – they want to know about every foreign account you can access, control, or benefit from.

That logic drives the 100% reporting rule: each US person who files separately reports the full maximum value of a joint account, not a fractional share.

Example: A US couple living in the UK holds a joint savings account at a British bank. The account’s maximum balance during 2025 was £50,000. Using an illustrative rate in place of the Treasury Reporting Rates of Exchange for December 31, 2025, that converts to roughly $63,500.

Because the couple also holds a separately owned account, they must each file their own FBAR. Each spouse reports the full $63,500 on their individual FBAR – not $31,750.

What to report vs. what not to report:

 

This rule applies whether the joint account is a checking account, savings account, brokerage account, or any other qualifying foreign financial account.

See our guide to FBAR maximum account value for the full calculation method.

Common FBAR joint filing mistakes to avoid

The following errors are the ones TFX CPAs see most often in FBAR filings from married couples. Each is paired with the correct action.

Common mistakes for joint FBAR filers:

 

Pre-filing checklist:

• Confirmed all reportable accounts of the non-filing spouse are jointly owned
• Form 114a completed, signed by both spouses, and stored in records
• Maximum value identified for each account – peak during the year, not the December 31 balance
• All values converted to USD using the December 31, 2025, Treasury rate
• Closed accounts included with their pre-closure maximum value
• Each separately owned account reported on the owning spouse’s individual FBAR

Principal joint owner information (Part III): what it means and how to fill it out

When you report a jointly owned foreign account on your FBAR, Part III asks for two specific pieces of information. These fields trip up a lot of filers.

• Number of joint owners – Item 24: Enter the total count of other people who own the account, excluding yourself. The FinCEN FBAR Line Item Filing Instructions say: “Do not count the filer when determining the number of joint owners.” If you and your spouse share an account and no one else is on it, you enter “1.”
• Principal joint owner information – Items 25–33: Enter the details of the main joint owner other than the filer: name, address, and taxpayer identification number.

If the filer’s spouse has an interest in the account, the spouse is the principal joint owner. Enter the joint owner’s SSN, ITIN, or EIN if known. If no US TIN exists, enter a foreign TIN if available. If no TIN is known, the field may be left blank.

Part III field-by-field guidance:

 

Make sure the name and identifying details you enter match the account documentation at the financial institution exactly. Discrepancies between your FBAR and the bank’s records can create complications during any future review.

Examples for Part III fields

The following three scenarios show how to apply the Part III rules in practice.

Part III examples for joint FBAR accounts:

 

In Scenario 3, note that a business partner cannot use the spouse exception – both of you file your own FBARs, and each reports the full account value. For FBAR principal joint owner information, enter the identifying details of whichever other owner you choose to list as the principal joint owner.

FinCEN’s instructions specify the filer’s spouse as principal when the spouse is a co-owner, but they don’t set a selection order among non-spousal co-owners. Many filers default to whoever is listed first on the account agreement for consistency, but any of the other owners can be used.

When the joint owner is a non-US spouse with no SSN or ITIN, enter a foreign TIN if available. If no TIN is known, you may leave that field blank – but complete all other identifying fields: name and address.

Joint account with a non-US citizen spouse: who files FBAR and what gets reported

If you are a US citizen or resident alien married to a foreign national, the reporting rules follow the same aggregate-threshold logic as any other FBAR situation.

As a US person, you must file an FBAR if the aggregate maximum value of all your reportable foreign financial accounts exceeded $10,000 at any point during 2025.

Once the aggregate crosses $10,000, you report every reportable account – including a joint account whose individual value may be well below $10,000.

Your non-US citizen spouse generally has no FBAR obligation, because the FBAR requirement applies only to “US persons” – a category that includes US citizens, green card holders, and resident aliens, but not foreign nationals who do not otherwise meet that definition.

If your spouse holds a green card or meets the substantial presence test, they may qualify as a US person and would then have their own filing obligation.

Example: You hold a joint savings account with your non-US spouse with a maximum value of $8,000, plus an individual checking account abroad with a maximum value of $5,000. Your aggregate is $13,000 – above $10,000. You must file an FBAR and report both accounts. Your non-US spouse has no FBAR filing obligation.

Who files and what gets reported – mixed-citizenship couples:

 

Common mistakes for mixed-citizenship couples:

• Assuming your non-US spouse’s individual accounts never appear on your FBAR. You do not report your spouse’s individual accounts unless you have a financial interest in them or signature authority over them. Being married alone does not create a reporting obligation for accounts held solely in your spouse’s name.
• Applying the $10,000 test per account instead of in aggregate.
• Assuming the non-US spouse is automatically exempt – check whether they hold a green card or meet the substantial presence test.

See our guide to reporting Wise and Revolut accounts on FBAR for fintech accounts commonly held by mixed-citizenship couples.

Joint accounts with parents or other relatives: do you “file jointly”?

There is no joint FBAR filing option for parents, siblings, or any other relative who is not your spouse. That option exists only for married couples, and even then, only under the conditions described above.

Each US person files only if that person’s aggregate maximum value of reportable foreign accounts exceeded $10,000 during the year.

If you and a parent share a foreign account and you both qualify as US persons, each of you files your own FBAR and reports the full maximum balance of that account independently.

Who the co-owner is – and what to do:

 

A common expat scenario: An adult child returns to the US after years abroad and remains on a joint bank account with a parent in the home country. If the parent is also a US person, both must file – each reporting the account’s full value. The joint account does not reduce either person’s reporting obligation.

Currency conversion for joint accounts (which rate to use)

Use the Treasury Reporting Rates of Exchange for December 31 of the year being reported. For tax year 2025, that means the rate published for December 31, 2025.

Apply the same rate consistently to all accounts being reported on the same FBAR – do not mix rates from different dates. Use the year-end rate even if the account peaked at a different time during the year.

If Treasury does not publish a rate for a particular currency, you may use another verifiable exchange rate and must retain records supporting that rate. Document the source, the rate applied, and the date.

Worked example:

 

Both accounts exceed $10,000 in aggregate. Each US-person filer reports both accounts at their full USD-converted maximum value.

Round each converted amount up to the next whole dollar. See our guide to FBAR exchange rates for the full conversion rules and where to find the rates.

Records to keep after filing a joint FBAR

FinCEN requires FBAR-related records to be retained for at least five years from the FBAR due date. For tax year 2025 accounts, that means keeping records until at least April 15, 2031.

Records must be available for inspection by FinCEN or the IRS on request.

Document retention checklist:

 

Work with a tax professional

Professional help adds the most value in specific situations – not every joint FBAR needs it.

When professional review is worth considering:

• Mixed-citizenship couples where one spouse is a US person and the other is not – reporting obligations and thresholds need careful analysis
• Missing records or incomplete bank statements for prior years
• Late FBARs or years of unfiled reports that may qualify for Streamlined Filing
• Multiple foreign accounts across several countries with different currencies
• Accounts involving signature authority, trusts, or foreign business entities

TFX has helped thousands of Americans abroad with FBAR filings, amendments, and late filings – including cases involving joint accounts, non-US spouses, and complex ownership structures.

Bring these to your consultation:

• Account statements for each foreign account, covering the full reporting year
• Account ownership documents showing who is listed on each account
• Prior-year FBARs and tax returns, if available
• Form 114a, if you have previously filed jointly
• Any IRS correspondence related to foreign account reporting
