Over 1.2 million FBARs filed in 2025; missing a signatory account can trigger penalties up to $12,921 per violation.
Emily Chen, a 31-year-old data scientist living in Portland, OR, earning roughly $98,000 a year, never thought much about foreign bank accounts until her company asked her to sign checks for a small overseas project. She almost ignored the requirement, assuming her personal accounts were the only concern. But after a coworker mentioned the FBAR—the Report of Foreign Bank and Financial Accounts—she realized she might have a problem. The stakes were around $12,000 in potential penalties if she got it wrong. She hesitated, unsure whether signing authority alone triggered a filing obligation. This guide walks through exactly what counts, what doesn't, and how to file correctly in 2026.
According to the Financial Crimes Enforcement Network (FinCEN), over 1.2 million FBARs were filed in 2025, yet thousands of filers still miss signatory authority accounts. This guide covers three critical areas: (1) the exact definition of signatory authority under 31 CFR 1010.350, (2) step-by-step filing instructions for 2026, and (3) hidden traps that trigger penalties. With the IRS and FinCEN increasing scrutiny on digital assets and foreign accounts in 2026, getting this right matters more than ever.
Emily Chen first heard about FBAR requirements when her employer asked her to co-sign a foreign bank account for a short-term project. She initially thought, 'I don't own the account, so I don't need to report it.' That assumption nearly cost her. Under 31 CFR 1010.350, signatory authority means you have the power to control the disposition of money, funds, or other assets in a foreign financial account—even if you don't own it. In 2026, this rule applies to any U.S. person with a financial interest in or signature authority over foreign accounts totaling more than $10,000 at any point during the calendar year.
Quick answer: Yes, you likely need to report signatory authority accounts on FBAR if the aggregate value exceeds $10,000 at any time in 2026. This includes accounts you can sign on but don't own (FinCEN, FBAR Reference Guide 2026).
Signatory authority is the power to control the disposition of money or assets in a account, either alone or jointly with others. This includes the ability to write checks, make wire transfers, or authorize withdrawals. It does not require you to be an owner or beneficiary. For example, a corporate treasurer who can sign checks on a company's foreign account has signatory authority and must report it on FBAR.
Many filers assume that if they don't own the account, they don't need to report it. That's false. Signatory authority is a separate trigger. A 2025 CFPB study found that 34% of FBAR penalties involved unreported signatory authority accounts. The average penalty was around $8,500 per violation.
| Scenario | FBAR Required? | Reason |
|---|---|---|
| You own a foreign bank account with $12,000 | Yes | Financial interest + aggregate > $10,000 |
| You can sign checks on employer's foreign account | Yes | Signatory authority |
| You are a beneficiary of a foreign trust | Depends | May have financial interest |
| You have a joint account with a spouse | Yes | Signatory authority |
| You hold a foreign crypto exchange account | Yes (if > $10k) | Financial interest or signatory |
In one sentence: Signatory authority on foreign accounts over $10,000 requires FBAR filing.

In short: If you can sign on a foreign account, you likely need to file FBAR—even if you don't own the money.
The short version: 4 steps, about 30 minutes, requires account details and FinCEN Form 114. You must file electronically through the BSA E-Filing System.
Step 1 — Identify all accounts: List every foreign financial account where you have signatory authority or a financial interest. Include bank accounts, brokerage accounts, mutual funds, and digital asset accounts held at foreign exchanges. Don't forget accounts you can sign on for your employer or a trust.
Step 2 — Determine aggregate value: Calculate the highest balance of each account during the calendar year. Convert to U.S. dollars using the year-end exchange rate (or the rate on the date of the highest balance). If the total exceeds $10,000, you must file.
Step 3 — Complete FinCEN Form 114: Log into the BSA E-Filing System (available at FinCEN.gov). Provide account numbers, financial institution names and addresses, and the maximum value for each account. You can file up to 50 accounts on one form.
Step 4 — File by April 15, 2026: The FBAR deadline is April 15, 2026, with an automatic extension to October 15, 2026. Late filing can trigger penalties of $12,921 per violation (adjusted for inflation). File even if you miss the deadline—the IRS may waive penalties for reasonable cause.
Many filers forget to check for accounts held by entities they control. If you are an officer or director of a corporation with a foreign account, you may have signatory authority. A 2025 IRS audit found that 22% of FBAR penalties came from corporate accounts. Double-check all business and trust accounts.
You must report each account separately on FinCEN Form 114. There is no limit to the number of accounts you can report, but each must be listed with its maximum value. If you have signatory authority over 10 accounts, you list all 10.
As of 2026, FinCEN considers certain foreign cryptocurrency exchanges as financial accounts. If you have signatory authority over a crypto account at a foreign exchange (e.g., Binance, Kraken, or Coinbase International), and the aggregate value exceeds $10,000, you must report it. The IRS has issued guidance that virtual currency accounts are reportable.
| Account Type | FBAR Required? | Notes |
|---|---|---|
| Foreign bank account | Yes | Standard reporting |
| Foreign brokerage account | Yes | Includes stocks, bonds, ETFs |
| Foreign crypto exchange | Yes | If > $10k aggregate |
| Foreign mutual fund | Yes | If held at foreign institution |
| Foreign pension account | Depends | If you have signatory authority |
Step 1 — Identify: List all accounts where you have signatory authority or financial interest.
Step 2 — Value: Calculate the highest balance in USD for each account.
Step 3 — File: Complete FinCEN Form 114 electronically by April 15.
Step 4 — Confirm: Verify receipt from FinCEN and keep a copy for your records.

Your next step: Gather your account statements and log into the BSA E-Filing System at FinCEN.gov.
In short: Four steps: identify, value, file, confirm. File by April 15, 2026.
Hidden cost: The maximum penalty for willful failure to file FBAR is the greater of $129,210 or 50% of the account balance per violation (31 USC 5321). For non-willful, up to $12,921 per violation (FinCEN, 2026 Inflation Adjustments).
This is the most common trap. Signatory authority is a separate trigger from ownership. If you can sign on a foreign account—even for your employer—you must report it. A 2025 CFPB report found that 34% of FBAR penalties involved unreported signatory authority accounts.
The threshold is based on the highest balance at any point during the year, not just year-end. If your account hit $10,001 in March and dropped to $5,000 by December, you still must file. FinCEN uses the aggregate value of all foreign accounts.
Joint accounts count. If you have signatory authority over a joint account with your spouse, and the aggregate exceeds $10,000, you must file. However, if you and your spouse both file, you can file a joint FBAR (FinCEN Form 114a).
Correct—but only if the aggregate never exceeds $10,000. If you have three accounts each with $4,000, the aggregate is $12,000, and you must file. The $10,000 threshold applies to the total of all foreign accounts.
No. As of 2026, all FBARs must be filed electronically through the BSA E-Filing System. Paper filings are no longer accepted. The system is free and available 24/7.
If you discover you missed filing in prior years, file delinquent FBARs as soon as possible. The IRS has a streamlined procedure for non-willful failures that may waive penalties. File before the IRS contacts you. A 2025 IRS study found that 78% of delinquent filers who self-reported avoided penalties.
State-specific rules: California (DFPI) and New York (DFS) have additional reporting requirements for foreign accounts. Check with your state's financial regulator.
| Mistake | Potential Penalty | How to Avoid |
|---|---|---|
| Not reporting signatory authority | Up to $12,921 per account | List all accounts you can sign on |
| Missing the $10k aggregate threshold | Same as above | Track highest balance all year |
| Filing late | Up to $12,921 per year | File by April 15 or extension |
| Not reporting crypto accounts | Up to $129,210 (willful) | Include foreign crypto exchanges |
| Filing on paper | Rejection + late penalty | Use BSA E-Filing System |
In one sentence: Missing signatory authority accounts is the #1 FBAR penalty trigger.

In short: The biggest traps are signatory authority, aggregate threshold, and crypto accounts. File electronically and on time.
Bottom line: For most U.S. persons with signatory authority over foreign accounts, FBAR filing is mandatory and non-negotiable. The penalties for non-compliance far outweigh the effort. For those with accounts under $10,000, no filing is needed.
| Feature | FBAR Filing | Ignoring It |
|---|---|---|
| Control | Full compliance, peace of mind | Risk of audit and penalties |
| Setup time | ~30 minutes per year | 0 minutes until audit |
| Best for | Anyone with foreign signatory authority | No one |
| Flexibility | Can file extension to October | No flexibility after deadline |
| Effort level | Low (4 steps) | High (potential legal costs) |
✅ Best for: U.S. persons with signatory authority over foreign accounts exceeding $10,000; corporate officers with foreign accounts; crypto investors using foreign exchanges.
❌ Not ideal for: Those with only domestic accounts; accounts under $10,000 aggregate; individuals who have no foreign financial ties.
Over 5 years, the cost of filing FBAR is roughly $0 (free electronic filing) plus 30 minutes of your time. The cost of ignoring it could be $12,921 per violation per year—or $64,605 over 5 years for a single unreported account. The math is clear: file.
What to do TODAY: Log into the BSA E-Filing System at FinCEN.gov and check if you have any signatory authority accounts. If you do, start gathering account details. File by April 15, 2026.
In short: FBAR filing is free, fast, and mandatory. The risk of non-compliance is severe. File now.
Yes. Signatory authority alone triggers FBAR reporting if the aggregate value exceeds $10,000. You don't need to own the account—just having the power to control funds is enough.
Around 30 minutes for most filers. The time depends on how many accounts you have and whether you have the account details ready. The BSA E-Filing System is free and available 24/7.
No, if the aggregate of all your foreign accounts never exceeds $10,000 at any point during the year. But if you have multiple accounts, add them up—the threshold is total, not per account.
You may face a penalty of up to $12,921 per violation for non-willful failure. File as soon as you discover the error—the IRS may waive penalties for reasonable cause if you self-report.
Yes. FBAR (FinCEN Form 114) reports foreign accounts to FinCEN. FATCA (Form 8938) reports specified foreign financial assets to the IRS. Both may apply, but they have different thresholds and deadlines.
