Tax FBAR Document
What the Tax FBAR Document Is
Why the FBAR Matters for U.S. Tax Compliance
Accurate FBAR reporting helps satisfy federal disclosure obligations, reduce exposure to civil and criminal enforcement by FinCEN and the IRS, and supports correct tax administration for foreign-held assets.
Who Typically Prepares and Files an FBAR
The FBAR is prepared by the U.S. person or an authorized filer (tax professional or corporate officer) responsible for foreign account reporting.
- Individual taxpayers with foreign bank or brokerage accounts
- Tax professionals and enrolled agents filing on behalf of clients
- Corporate officers or treasurers for entity-level account disclosures
Common preparers include individual taxpayers, CPAs, enrolled agents, corporate compliance teams, and international payroll or treasury personnel.
Who Signs or Authorizes an FBAR Filing
Individual Filer
A U.S. person (citizen or resident) who directly owns or has signature authority over foreign accounts. The filer must ensure accurate account details and may authorize a tax professional to e-file on their behalf, retaining proof of authorization.
Authorized Filer
A tax professional, CPA, or corporate officer who registers as an authorized e-filer in the BSA E-Filing System. The authorized filer submits Form 114 electronically and must keep client consent and filing confirmations for records.
