This 8938 vs FBAR line table matches aligned foreign account entry fields for official IRS reporting requirements. Both forms mandate disclosure of foreign financial assets held by U.S. persons, and mismatched values or account details across the two filings are one of the most common triggers for IRS follow-up correspondence and audit scrutiny. This reference guide maps corresponding entry lines across both forms to reduce manual entry error, ensure consistent reporting, and simplify record keeping for your tax year files. All guidance on this page is for educational purposes only; you should confirm all entries with a licensed tax preparer before submission, as Field Ledger does not provide tax preparation or filing services.
Form 8938 account value entry column
Form 8938, officially titled Statement of Specified Foreign Financial Assets, requires filers to report account values in dedicated columns tied to the type of asset being disclosed. For depository accounts including checking, savings, and time deposit accounts held at foreign financial institutions, values are entered in Part II, Column (d), which captures the maximum value of the account during the applicable tax year. For custodial accounts holding stocks, bonds, mutual funds, or digital asset holdings on foreign exchanges, values are entered in Part II, Column (g), also reflecting the maximum annual value. For other specified foreign assets including foreign pension accounts, life insurance contracts with cash value, and holdings in foreign entities, values are entered in Part II, Column (j). All values must be converted to U.S. dollars using the IRS-endorsed end-of-year exchange rate for the tax year, or the exchange rate in effect on the date the asset reached its maximum value during the year, if that rate is consistently applied across all reported assets for that tax year. You must retain copies of the exchange rate source materials used for these calculations in your filing folder to support your entries if requested.
FBAR account line corresponding input box
The FBAR, or FinCEN Form 114, Report of Foreign Bank and Financial Accounts, requires the same maximum annual account value disclosure for all reportable foreign accounts, with the corresponding input box located in Part II, Item 15a for individual accounts held directly by the filer, and Part III, Item 24a for accounts held by entities owned or controlled by the filer. Like Form 8938, the FBAR requires values to be converted to U.S. dollars using a consistent, documented exchange rate source, so entries for the same account should match exactly unless there is a legitimate, documentable reason for a discrepancy. Before aligning values, cross-check the corresponding account identifiers on both forms: confirm the foreign financial institution name, address, and account number listed on Form 8938 match the entries in FBAR Part II, Items 12 through 14 for individual accounts, or Part III, Items 21 through 23 for entity-held accounts, to ensure you are mapping values for the same account, not a separate account held at the same institution. If you are filing a consolidated FBAR for a business with multiple foreign accounts, you will need to map each individual account line to its corresponding Form 8938 entry if the entity is classified as a specified foreign financial asset required to be reported on your personal 8938 filing.
Cross-reference entry note attachment section
Both the IRS and FinCEN allow filers to attach explanatory notes to their filings if the reported values for the same account differ across Form 8938 and the FBAR. This section of your filing folder should hold all dated, signed explanatory notes that clearly outline the rationale for any value discrepancy, with each note tied to a specific account number and line number on both forms for easy reference. You do not need to attach notes for accounts where values match exactly, but you should still mark those accounts as aligned on your line comparison table for your own record keeping. Illustrative example: a note for a custodial account holding digital assets might read “Account #78901 at KuCoin: 8938 value is $217,000, FBAR value is $222,000, difference due to 8938 excluding $5,000 in non-reportable physical hardware wallet holdings linked to the same custodial account per IRS Publication 54 guidelines.” All notes should be written in clear, plain language, avoid jargon, and reference specific IRS or FinCEN guidance to support the discrepancy rationale where possible. You should retain one copy of each note in your 8938 filing section and one copy in your FBAR filing section, so you can quickly produce supporting materials if either agency requests clarification.
Line comparison table filing deadline schedule
The line comparison table below maps corresponding entry lines across Form 8938 and the FBAR, along with allowed discrepancy rationale codes to standardize your record keeping. You should complete this table no later than 2 weeks before your earliest filing deadline to give yourself time to resolve discrepancies, gather supporting documentation, or prepare explanatory notes as needed. Form 8938 is filed alongside your individual income tax return, with a standard deadline of April 15, and the same extension options available for your Form 1040, pushing the deadline to October 15 if you file for an extension. The FBAR has a standard deadline of April 15, with an automatic 6-month extension to October 15, no separate extension request required. If you file for an extension for your income tax return, you should align your 8938 and FBAR filing dates to ensure consistency across both submissions.
| Form 8938 Line Location | Form 8938 Value Column | FBAR Form 114 Value Line Location | Account Type | Allowed Discrepancy Rationale Code |
|---|---|---|---|---|
| Part II, Line 1a | Column d | Part II, Item 15a | Foreign depository account (checking, savings, CD) | D1 (no discrepancy allowed unless exchange rate source is formally documented) |
| Part II, Line 1b | Column g | Part II, Item 15a | Foreign custodial account (stocks, bonds, digital assets) | D2 (discrepancy allowed if non-reportable assets are held in the same custodial wrapper) |
| Part II, Line 1c | Column j | Part II, Item 15a | Foreign pension or deferred compensation account | D3 (discrepancy allowed if Form 8938 only reports the vested portion of the account balance) |
| Part II, Line 2a | Column d | Part III, Item 24a | Foreign depository account held by a filer-owned disregarded entity | D1 (no discrepancy allowed unless exchange rate source is formally documented) |
| Part II, Line 2b | Column g | Part III, Item 24a | Foreign custodial account held by a filer-controlled foreign grantor trust | D4 (discrepancy allowed if partial trust assets are excluded from Form 8938 per grantor trust reporting rules) |
You should save a dated copy of the completed table in both your current tax year filing folder and your permanent foreign asset records folder, so you can reference prior year mappings to ensure consistent reporting for accounts you hold for multiple tax years.
Submission document folder labeled divider tab
Create a dedicated divider tab in your tax year filing folder labeled “8938/FBAR Line Comparison” to store all relevant supporting materials for your aligned filings. Place this tab between your main Form 1040 supporting documents tab and your other foreign reporting forms tab, so you can quickly locate the comparison materials if you receive an inquiry from the IRS or FinCEN. Behind the tab, store the following items: a printed copy of the completed line comparison table, copies of all cross-reference explanatory notes for accounts with value discrepancies, exchange rate source documentation used to convert foreign currency values to U.S. dollars, official account statements showing the maximum value of each reported account during the tax year, and confirmation receipts for both your filed Form 8938 and filed FBAR. If you use a digital filing system, create a dedicated password-protected folder with the same label, and save scanned copies of all physical materials alongside digital copies of your filed forms. You should retain these materials for a minimum of 7 years from the date of your filing, per IRS record retention requirements for foreign financial asset reporting. Pre-formatted divider tab labels for this section are available for download as part of Field Ledger’s free tax record keeping template pack.
Print a copy of your completed line comparison table and cross-reference it against your draft Form 8938 and draft FBAR entries before submitting either form to the IRS or FinCEN.
