Form 706-NA (2024): Nonresident Estate Tax Checklist
Purpose and Scope
Form 706-NA is used to compute federal estate taxes and, when applicable, generation-skipping transfer tax for nonresident alien decedents who were neither domiciled in the United States nor U.S. citizens at death. This Estate Tax Return applies when U.S. assets create transfer taxes under applicable Internal Revenue Code provisions.
Although Form 706-NA focuses on U.S.-situated property for taxability, worldwide gross estate values must still be determined for reporting and deduction computations. This requirement affects filing requirements, proportional deductions, and treaty-based estate planning positions.
Core Concepts to Apply Before Starting
Estate Tax Nonresident Status Is Based on Domicile
For estate tax purposes, nonresident classification depends on citizenship and domicile rather than income tax residency concepts such as the substantial presence test or green card status.
Immigration indicators such as an immigrant visa, a driver's license, or voter registration are evaluated only as factual evidence of domicile.
This distinction is critical for nonresident alien decedents whose ties to the United States may appear substantial but do not establish estate tax residency. Misapplying income tax standards can result in incorrect estate tax inclusion.
U.S.-Situated Property Rules Include Key Exceptions
Not all assets connected to the United States are treated as U.S. situs property for Form
706-NA reporting. Certain deposits, debt obligations, and financial accounts may be excluded depending on statutory exceptions and Treasury regulations.
Each asset must be classified using the specific location rules for estate tax purposes. Incorrect situs assumptions frequently cause errors in gross estate asset reporting and estate tax lien exposure.
Worldwide Gross Estate Must Be Determined
Even though only U.S.-situated property appears on the U.S. asset schedules, worldwide gross estate determination remains mandatory. Foreign values directly affect deduction limits, tax credits, and treaty relief calculations.
Failure to determine worldwide values may result in disallowed deductions or delayed issuance of an estate tax closing letter. Proper documentation supports accurate estate management and
IRS review.
Credits and Exclusion Rules Differ From Form 706
The unified credit exemption and federal estate tax exemption applicable to U.S. citizens do not apply in the same manner to Form 706-NA filings. NRNC estate tax computations rely on specific statutory credits rather than the annual exclusion framework.
Assuming portability election availability or the Deceased Spousal Unused Exclusion application is incorrect for nonresident estates. Credit computations must follow the Form 706-NA structure.
Ten-Step Checklist
Step 1: Confirm filing category and identity documentation
Confirm the decedent qualifies as a nonresident alien based on citizenship and domicile at death. Collect documentation supporting domicile, citizenship, community affiliations, and executor authority.
Evaluate whether treaty relief under Death Tax Treaties will be claimed. Treaty positions require clearly labeled statements and supporting computations.
Step 2: Determine the entire gross estate worldwide
Compile a complete worldwide inventory including real estate, securities, business interests, trust corpus interests, annuities, life insurance, and tangible personal property. This inventory establishes the estate tax inclusion period for Form 706-NA purposes.
Worldwide valuation is required even when tax liability arises only from U.S. assets. The Internal
Revenue Service relies on worldwide disclosure to validate proportional deductions.
Step 3: Identify U.S.-situated assets
From the worldwide inventory, determine which assets are U.S.-situated under Form 706-NA location rules. Standard inclusions involve U.S. real estate, tangible personal property in the
United States, and U.S. corporate stock.
Apply statutory exceptions carefully, particularly for bank deposits and certain debt obligations.
Incorrect classification can inflate the taxable estate.
Step 4: Prepare U.S.-situs schedules and required Form 706 schedules
Complete Schedule A and other relevant schedules for U.S.-situated property using applicable valuation methods. Attach Form 706 schedules when required for marital deduction, charitable deduction, or prior transfer credit claims.
Follow Form 706 valuation rules when instructions direct cross-reference usage. Supporting documentation must align with fair market value requirements.
Step 5: Report foreign totals where required
Report the total value of non-U.S. assets in the appropriate section of the return. Maintain reconciliation between worldwide inventory and reported U.S. and non-U.S. totals.
Foreign documentation may include foreign estate filings, asset statements, or appraisals.
These records support deduction eligibility and treaty relief positions.
Step 6: Compute allowable deductions using NRNC proportional rules
Compute deductions using the proportional method required for nonresident estates.
Administration expenses, debts, and losses are generally limited based on the ratio of U.S.
assets to the worldwide gross estate.
Complete worldwide disclosure is essential for deduction allowance. Missing foreign values may cause procedural denial regardless of substantive eligibility.
Step 7: Compute tax and apply available credits
Compute estate taxes using the applicable rate schedule and NRNC credit framework. Avoid mischaracterizing credits as prohibited under Internal Revenue Code section 2102(b).
Apply tax credits only where permitted and supported. Unified credit exemption rules differ materially from Form 706 citizen filings.
Step 8: Apply credit for tax on prior transfers correctly
If claiming credit for tax on prior transfers, apply the timing rule covering deaths within ten years before or two years after the decedent’s death. Percentage scaling depends on statutory timing intervals.
Attach required schedules and supporting documentation. Failure to apply timing rules correctly may invalidate the credit.
Step 9: Complete signature and identification requirements
Sign and date the return as executor or authorized representative. Enter a Social Security number only when applicable, or follow instructions when no SSN or ITIN exists.
Do not assume an identification number must be created. Improper entries delay processing and the issuance of IRS transfer certificates.

Step 10: Assemble, review, and file using current instructions
Review the return for internal consistency, attachment completeness, and reconciliation accuracy. Attach required documents, including death certificate, treaty statements, and Form
706 schedules.
File using the current Internal Revenue Service address for Form 706-NA. Confirm filing deadline compliance and request an extension of time using Form 4768 if needed.
Form-Specific Limitations and Reminders
Worldwide estate workpapers must be retained even though only U.S.-situated assets appear on the primary schedules. Omission of worldwide values commonly results in deduction denial.
Do not default to the federal estate tax exemption or the portability election. NRNC estates are subject to a distinct statutory framework.
Form 5173 and other certifications should be included only when required. Avoid unnecessary attachments.
Final Quality-Control Review
Confirm all U.S.-situated assets are properly classified and valued using accepted valuation methods. Ensure foreign totals are reported where required and supported.
Verify deductions, credits, and treaty positions are correctly computed and documented. Proper review supports timely filing and reduces the service's time to issue an estate tax closing letter or TC 421 account transcript.
