FBAR FinCEN 114 Preparation: 5 Essential Rules for CPA Firms

This post is general information, not legal or tax advice. Consult a qualified professional about your clients' specific FBAR situations.

The $10,000 aggregate threshold is where it starts. Your client holds a checking account in Germany with a $4,000 balance and a brokerage account in Canada worth $7,500. Neither triggers a filing obligation on its own. Together, they require a FinCEN 114. That distinction is exactly what FBAR FinCEN 114 preparation is designed to catch, and it's the kind of exposure clients consistently underreport because they don't know it applies to them.

At BusAcTa Advisors, our offshore tax preparation team flags FBAR exposure before the return is assembled, not after an IRS notice arrives. Effective FBAR FinCEN 114 preparation starts before the organizer goes out. Here are the five essential rules CPA firms need to build into their process.

Who Must File and the $10,000 Aggregate Rule

A US person must file FinCEN 114 if they had a financial interest in, or signature authority over, one or more foreign financial accounts, and the aggregate maximum balance across all those accounts exceeded $10,000 at any point during the calendar year.

US person is broader than most clients assume. It includes US citizens, green card holders, resident aliens, and domestic entities: corporations, partnerships, LLCs, trusts, and estates. Permanent resident status doesn't exempt them.

Two things catch people off guard on the threshold:

• Aggregate, not per account. The test is the combined maximum across all foreign accounts, not any individual account balance.

• Maximum balance, not year-end balance. If an account reached $11,000 in March and dropped to $2,000 by December, FBAR is required for that year.

What counts as a foreign financial account includes foreign bank accounts, brokerage and securities accounts, foreign mutual funds, foreign-issued life insurance with cash surrender value, and most foreign retirement accounts. This comes up regularly in individual tax preparation for clients with ties to multiple countries.

FBAR Penalties After Bittner v. United States

Penalty exposure is what makes FBAR FinCEN 114 preparation non-negotiable for every firm handling international clients. In Bittner v. United States, 598 U.S. 85 (2023), the Supreme Court held that non-willful FBAR penalties are assessed per report, not per account. That reversed what the government had argued in enforcement cases and significantly reduced exposure for clients with multiple unreported accounts.

The two penalty tiers:

• Non-willful: Up to $10,000 per unfiled annual report, at IRS discretion.

• Willful: The greater of $100,000 or 50% of the highest account balance per violation. Criminal penalties can also apply, including fines up to $250,000 and imprisonment up to five years.

Courts have defined "willful" to include willful blindness. A client who was generally aware of foreign account reporting obligations but didn't ask whether they applied can still be found to have acted willfully. That's a fact pattern worth knowing when a client discloses accounts late.

The Bittner decision means non-willful penalties attach per annual report, not per account. A client with five unreported foreign accounts faces one non-willful penalty of up to $10,000, not five.

For clients who discover past non-compliance, the IRS offers the Streamlined Filing Compliance Procedures and the Voluntary Disclosure Program. Neither eliminates liability, but both result in significantly lower penalties than an audit assessment.

Signature Authority: The FBAR Rule Clients Don't Know

Can your client be required to file FBAR without owning a foreign account? Yes. Signature authority over a foreign account creates a filing obligation even when the client has no financial interest in it.

Common signature authority scenarios that get missed:

• An employee authorized to direct payments from their employer's foreign operating account

• A US officer of a foreign subsidiary who can authorize wire transfers from the entity's account

• A US trustee of a foreign trust that holds accounts at foreign institutions

The client may see the account as "the company's" or "the trust's" money. The filing obligation doesn't require ownership, only authority to control.

FinCEN has historically granted blanket filing extensions for certain signature-authority-only filers. But those extensions aren't guaranteed each year and shouldn't be relied on without checking current FinCEN guidance.

Signature authority creates an FBAR filing obligation regardless of financial interest. Employees, officers, and trustees are the three most commonly missed categories.

FBAR FinCEN 114 Preparation: Filing Mechanics and Deadlines

FinCEN 114 is filed electronically through FinCEN's BSA E-Filing System. It's not attached to the tax return. Many clients don't realize this is a separate filing obligation with a separate deadline.

The deadline is April 15, with an automatic extension to October 15. No extension request is required. Before the Surface Transportation and Veterans Health Care Choice Improvement Act of 2015, the deadline was June 30 with no extension. The current rule has applied since the 2016 filing year.

FBAR is separate from FATCA Form 8938. Both may apply to the same accounts but with different thresholds. FBAR's aggregate threshold is $10,000. Form 8938's threshold starts at $50,000 for single filers residing in the US ($75,000 if that balance was reached at any point during the year). A client who must file Form 8938 may or may not also need to file FBAR. Many need both.

5 Intake Questions That Surface FBAR Exposure

Your client intake process is the most important FBAR FinCEN 114 preparation control. If the question doesn't get asked, the disclosure doesn't happen. Don't assume Schedule B Part III covers it. The question is frequently misread, and clients routinely leave foreign account disclosures blank on self-completed organizers.

Add these five questions to your intake workflow:

• Did you hold any financial accounts at foreign banks or institutions during the year, including bank, brokerage, retirement, or insurance accounts?

• Did any of those accounts have a combined balance exceeding $10,000 at any point, even temporarily?

• Do you have signature authority over any account held by a foreign company, employer, or trust, even if you have no personal funds in it?

• Are you a trustee, officer, or authorized signatory for any foreign entity that maintains bank or investment accounts outside the US?

• Have you received wire transfers from abroad that may be connected to a foreign account you haven't mentioned?

Any "yes" or "possibly" should trigger a deeper review before the return is prepared.

How Offshore Tax Prep Teams Catch What Clients Miss

When FBAR FinCEN 114 preparation is integrated into your offshore workflow, it creates a systematic checkpoint. Intake flags, foreign addresses, international wire transfers, or Schedule B Part III answers that require attention cause the file to be escalated before the return is assembled, not discovered during partner review.

BusAcTa's tax preparation process includes a preparer checklist that captures Schedule B Part III review on every return. Where Box 7a (interest from foreign accounts) or Box 7b (signature authority or financial interest in foreign accounts) indicates a "yes," the file is flagged before the return proceeds. Our quality control process ensures that step happens on every file, not just the ones that look international on the surface.

Does your current workflow include a structured FBAR checkpoint at the preparer level? If not, it's a gap worth closing before next filing season.

Conclusion

FBAR FinCEN 114 preparation is most valuable before the return is filed. The $10,000 aggregate threshold catches accounts clients don't think to mention. Signature authority creates obligations for employees and officers who never personally held foreign funds. And willful penalties, even after Bittner, can reach 50% of the highest account balance. The right intake questions and a structured preparer checkpoint catch most of these issues early, when the client still has options.

If your firm wants to build a more consistent FBAR checkpoint into your tax preparation process, schedule a call with BusAcTa Advisors. Our offshore tax preparation team works alongside your firm to surface foreign account exposure before the return reaches your desk.
