You Have More Than $10,000 in Mexican Bank Accounts—Do You Need to File an FBAR?

Imagine you live in Texas but still have several bank accounts in Mexico. None of the accounts individually has more than $10,000, so you assume there is nothing to report. Then your CPA adds the accounts together and tells you that you may have an FBAR filing requirement. How does that work?

Imagine this.

You are a U.S. citizen or U.S. tax resident with family and business connections in Mexico.

You maintain several Mexican accounts.

One checking account reached $4,000 during the year. A savings account reached $6,000. A small investment account reached $5,000.

You look at each account individually and think: “They're all under $10,000. I don't need an FBAR.”

But your CPA adds them together: $4,000 + $6,000 + $5,000 = $15,000.

Now we have an FBAR conversation.

The threshold generally looks at the aggregate value of qualifying foreign financial accounts—not simply whether one account exceeded $10,000.

What Is an FBAR?

FBAR stands for Report of Foreign Bank and Financial Accounts.

The official report is FinCEN Form 114.

The FBAR is separate from your Form 1040 and is filed electronically with the Financial Crimes Enforcement Network, commonly called FinCEN.

For taxpayers with international financial accounts, it can be an extremely important part of annual U.S. compliance.

Who Can Have an FBAR Filing Requirement?

Generally, FBAR rules can apply to a U.S. person who has a financial interest in or signature or other authority over qualifying foreign financial accounts when the applicable aggregate threshold is exceeded.

For individuals, this can include U.S. citizens and U.S. residents under applicable rules.

Someone does not necessarily need to have been born in the United States to enter the FBAR reporting system.

The $10,000 Threshold Is Aggregate

This is probably the most important concept.

The general threshold is not $10,000 per account.

Imagine Account A reaches $3,000, Account B reaches $4,000, and Account C reaches $5,000.

None individually exceeds $10,000.

Together they total $12,000.

The aggregate threshold may therefore be exceeded.

This is why your CPA needs to know about all of your foreign accounts—not simply the largest one.

It Is Not Based on Your December 31 Balance

Imagine your Mexican bank account had $75,000 in June.

You later used the money to purchase property.

By December 31, the account has only $2,000.

Telling your CPA only the year-end balance is not enough.

FBAR reporting generally looks at the maximum value during the calendar year, not simply the December 31 balance.

That $75,000 June balance can therefore be extremely important.

Imagine Moving the Same $50,000 Between Accounts

Suppose you have $50,000 in Mexican Bank A, transfer it to Mexican Bank B, and later transfer it into an investment account.

Economically, you may have had only $50,000 total.

But each account can have its own maximum value for FBAR reporting.

The reported maximum balances can therefore add up to more than your actual total wealth.

That is not necessarily an error. FBAR asks for account information and maximum values—not your net worth.

Which Accounts Can Count?

People hear “foreign bank account” and think only about checking and savings.

The rules can apply more broadly to qualifying foreign financial accounts.

Depending on the facts, this can potentially include checking accounts, savings accounts, certain brokerage accounts, securities accounts, investment accounts, and other qualifying financial accounts maintained outside the United States.

Give your CPA the complete account list rather than deciding which accounts count yourself.

What About Mexican Brokerage Accounts?

Imagine you have an investment account with a Mexican financial institution worth $250,000.

The account itself may need to be considered for FBAR purposes.

Separately, investments inside the account may create income-tax or other international reporting issues.

For example, certain foreign investment funds can potentially create PFIC reporting.

One brokerage account can therefore create more than one international tax question.

What About Cryptocurrency?

Foreign-account reporting involving digital assets can depend on the type of account, custodian, and rules applicable to the reporting year.

If you hold cryptocurrency through a foreign financial institution, exchange, or other foreign arrangement, tell your CPA.

Do not assume: “It's crypto, so FBAR never applies.”

The specific arrangement and current reporting rules should be reviewed.

What Does “Financial Interest” Mean?

The simplest example is an account you personally own.

Your name is on the account and the money belongs to you.

But financial interest can extend beyond the most obvious personal checking account.

Ownership through entities, nominees, agents, and other arrangements can potentially affect the analysis.

This is why business owners need to pay special attention.

What If Your Mexican Company Has a Bank Account?

Imagine you own 100% of a Mexican corporation.

The corporation has an operating account with $500,000, payroll account with $150,000, and investment account with $200,000.

You say: “Those aren't my accounts. They belong to the corporation.”

That is an important fact, but it does not automatically end the FBAR analysis.

Depending on your ownership and applicable rules, your relationship with the foreign entity and its accounts may need to be considered.

You may also have signature authority.

Your CPA needs the full structure.

Signature Authority Can Create FBAR Reporting

Imagine you do not own the Mexican company. You are simply its CFO.

The company has a Mexican bank account with $2 million and you are authorized to direct the bank to make payments.

Could the account matter to you for FBAR purposes? Potentially.

FBAR can apply not only when you have a financial interest in an account but also in certain situations involving signature or other authority.

It is not always enough to say: “It's not my money.”

What If You Have Signature Authority but Never Use It?

Suppose your name was added to a Mexican corporate bank account years ago.

You have never signed a check, initiated a wire, or logged into online banking, but legally you still have authority over the account.

The fact that you never exercised the authority does not necessarily mean it can be ignored.

We need to understand what authority you actually have.

What About Joint Accounts With Your Spouse?

Imagine you and your spouse jointly own a Mexican savings account that reaches $100,000.

If both spouses are U.S. persons, each spouse's FBAR obligation needs to be considered.

There are rules that can sometimes simplify reporting for spouses when specific requirements are satisfied, but do not simply assume: “We file a joint tax return, so one FBAR covers both of us.”

FBAR and Form 1040 are separate filing systems.

What If Your Spouse Is Not a U.S. Person?

Imagine you are a U.S. citizen and your spouse is a Mexican citizen who is not a U.S. person.

You jointly own a Mexican bank account.

Your spouse's U.S. reporting situation may differ from yours, but your own interest in the joint foreign account can still create an FBAR question.

The other owner's foreign status does not automatically make the account disappear from your reporting.

What If You Inherited the Account?

Imagine your father passes away in Mexico and you inherit a Mexican bank account containing $300,000.

Several questions may arise.

When did you legally obtain an interest in the account? What was its maximum value during the period you owned it? Was foreign inheritance reporting required? Did the account generate interest? Does Form 8938 apply?

FBAR may be only one piece of the inheritance analysis.

What If the Account Doesn't Earn Any Interest?

FBAR is an information-reporting regime.

An account does not necessarily need to generate taxable income to be reportable.

You can potentially have an FBAR requirement for an account that earns $0 of income.

Taxability and reporting are separate questions.

“But I Reported the Interest on My Tax Return.”

Reporting foreign interest on Form 1040 does not automatically satisfy the FBAR requirement.

And filing an FBAR does not automatically report interest income on your Form 1040.

They are separate obligations.

One reports income. The other reports qualifying foreign financial accounts.

You may need both.

What About Form 8938?

Form 8938 and FBAR are separate reporting regimes.

They have different thresholds, definitions, filing procedures, and potentially different assets covered.

Form 8938 is generally filed with the federal income-tax return.

FBAR is filed separately with FinCEN.

Filing one does not automatically replace the other.

Why Form 8938 Thresholds Can Be Much Higher

Form 8938 thresholds vary depending on factors such as filing status, whether you live in the United States or abroad, and the value of specified foreign financial assets.

That means someone can potentially have an FBAR requirement but no Form 8938 requirement—or potentially both.

Your CPA should evaluate them separately.

What If You Own Foreign Company Shares but No Foreign Account?

Imagine you directly own 30% of a Mexican company but do not personally own its bank account.

Form 8938 may potentially consider certain foreign financial assets beyond bank accounts, depending on applicable rules and thresholds.

FBAR generally focuses on foreign financial accounts.

Again, the two reporting regimes are not identical.

How Do We Determine the Maximum Balance?

For a bank account, we generally review statements or other reliable records to identify the maximum account value during the year.

For investment accounts, values can fluctuate.

Monthly or quarterly statements, transaction histories, year-end reports, and other financial records can be useful.

The goal is to determine a reasonable and supportable maximum value under the applicable rules.

Converting Pesos to Dollars

Your Mexican bank statements are likely denominated in pesos.

FBAR values are reported in U.S. dollars.

The applicable rules provide for converting the maximum foreign-currency value into dollars using the prescribed exchange-rate methodology.

Do not simply use today's exchange rate.

The reporting year matters.

When Is the FBAR Due?

The FBAR generally has an annual due date aligned with the individual income-tax filing season, with an automatic extension under current rules.

But do not think of FBAR as part of the Form 1040 extension process.

It is a separate filing and should be tracked separately.

What If You Forgot to File?

Imagine you had Mexican accounts for ten years and reported all interest income on Form 1040 but never filed an FBAR because nobody told you about it.

Now compare that with someone who knew about FBAR and intentionally concealed accounts.

Those are very different situations.

The appropriate correction strategy depends on whether income was properly reported, why the FBARs were missed, whether conduct was willful or non-willful, where the taxpayer lives, what other international forms were missed, and whether the IRS has already contacted the taxpayer.

Do not assume every late FBAR should be handled the same way.

Delinquent FBAR Procedures May Be Relevant in Some Cases

Certain taxpayers who properly reported and paid tax on income from foreign financial accounts but failed to file required FBARs may need to consider the applicable delinquent FBAR submission procedures, subject to their requirements.

Other taxpayers may need to consider streamlined procedures or another compliance path.

The correct approach depends on the complete facts.

Do not simply file years of late FBARs without first understanding the taxpayer's situation.

FBAR Penalties Can Be Significant

FBAR penalties can be serious, and the consequences can differ depending on the nature of the violation and facts.

That is why the distinction between willful and non-willful conduct can become extremely important in delinquent cases.

The correct approach is to determine what was required, what happened, why it happened, and then the proper correction procedure.

Don't Hide Accounts From Your CPA Because You're Embarrassed

Your CPA needs the complete account list.

Do not leave out an account because it was only open for two months, belongs to your company, was forgotten, is used by your spouse, does not earn income, has already been closed, has a low balance now, or is rarely used.

Tell your CPA.

Let the reporting rules determine whether it matters.

Create a Foreign Account Schedule Every Year

For clients with multiple foreign accounts, maintaining a simple annual schedule can make compliance much easier.

For each account, record the financial institution, country, account type, identifying information, owners, persons with signature authority, maximum annual value, currency, and whether the account was opened or closed during the year.

This makes annual FBAR preparation significantly easier.

Business Owners Need a Separate Account Review

If you own companies in Mexico, do not stop with personal accounts.

Review operating accounts, payroll accounts, savings, investment accounts, accounts of subsidiaries, and accounts where you have signature authority.

Then let your CPA determine which ones affect your personal FBAR.

Imagine Discovering the Problem Before the Deadline

Scenario One: Your CPA asks about foreign accounts during tax preparation. You provide the list, the aggregate threshold is reviewed, and the FBAR is filed on time.

Scenario Two: Ten years later, a new CPA asks: “Have you ever filed an FBAR?” You respond: “What's an FBAR?”

Now everyone is reconstructing years of account history and evaluating correction procedures.

The difference is simply asking the right question early.

A Simple Way to Remember the FBAR Rule

If you are a U.S. person with financial interests in or certain authority over accounts outside the United States, remember two things.

Do not look at only one account. Look at all qualifying foreign accounts together.

And do not look only at December 31. Look at maximum values during the year.

Those two concepts prevent many FBAR mistakes.
