What Is the Form 3520 Foreign Gift Threshold?

The Form 3520 foreign gift threshold is the dollar amount that triggers your obligation to report foreign gifts to the IRS. For 2026, the threshold is $100,000 for gifts from foreign individuals and estates, and $20,573 for gifts from foreign corporations and partnerships. These are reporting thresholds, not tax thresholds — you do not owe gift tax on foreign gifts you receive.

You must file Form 3520 if the total value of foreign gifts you receive in a single tax year exceeds either threshold. The threshold applies to aggregate gifts — you combine all gifts from a single donor and from their related parties to determine if you exceed the limit.

The legal authority for this requirement is IRC § 6039F. Congress enacted this law to give the IRS visibility into foreign wealth transfers, not to tax recipients. The penalty for failing to file is based on the gift amount, not because tax is owed, but because the information is required for tax administration.

The individual threshold ($100,000) is statutorily fixed and does not adjust for inflation. The corporate/partnership threshold adjusts annually based on the Chained CPI-U and is announced in a Revenue Procedure each fall. The 2026 threshold of $20,573 was calculated using the inflation adjustment formula in IRC § 6039F and confirmed by Revenue Procedure 2024-40.

If you receive gifts from both individuals and entities in the same year, you must check both thresholds separately. Crossing either threshold triggers the filing requirement. The tracker above handles both automatically.

Foreign Individual Gifts: The $100,000 Threshold

The $100,000 threshold applies to gifts from foreign individuals, estates, and other natural persons who are not U.S. citizens or residents. This threshold is per donor, aggregated with gifts from that donor's related parties.

You must aggregate all gifts from a single donor in a single tax year. If the total exceeds $100,000, you must file Form 3520 and report the gifts. The $100,000 threshold applies to each individual donor separately — not the total of all gifts from all donors.

Example: Your father gives you $60,000 and your mother gives you $50,000 in the same year. Your parents are related parties, so their gifts are aggregated: $60,000 + $50,000 = $110,000. You must file Form 3520 because $110,000 exceeds $100,000. If your uncle (unrelated) gives you $90,000 separately, you check his gifts alone against the $100,000 threshold.

What Counts as a "Foreign Individual"?

• Nonresident alien (NRA): Any individual who is not a U.S. citizen or U.S. resident for tax purposes
• Foreign estate: An estate of a decedent who was not a U.S. citizen or resident
• Foreign trust: Different rules apply (see special situations section)

Foreign Corporation / Partnership Gifts: The $20,573 Threshold (2026)

The $20,573 threshold applies to gifts from foreign corporations and foreign partnerships. This threshold is significantly lower than the individual threshold because Congress intended closer scrutiny of gifts from foreign entities.

Unlike the individual threshold, the corporate/partnership threshold is aggregated across all foreign corporations and partnerships — not per donor. You combine all gifts from all foreign corporations and partnerships in a single tax year. If the total exceeds $20,573, you must file Form 3520.

The threshold adjusts annually for inflation using the Chained CPI-U. The 2026 amount of $20,573 represents a $457 increase from 2025.

What Counts as a Foreign Corporation or Partnership?

• Foreign corporation: Any corporation incorporated outside the United States
• Foreign partnership: Any partnership organized outside the United States
• Gifts from foreign estates are treated under the individual threshold ($100,000), not the entity threshold

The $5,000 Itemization Rule: When and How to Apply

Once you cross the aggregate Form 3520 threshold ($100,000 for individuals or $20,573 for corporations), you must itemize each individual gift valued at $5,000 or more on Form 3520 Part IV, line 54. Gifts under $5,000 are aggregated and reported as a single total.

This rule applies only after the filing threshold is crossed. If you are below the aggregate threshold, you do not need to itemize — you simply report no gifts. The $5,000 rule is an itemization rule, not an additional threshold.

The tracker above automatically flags which of your gifts exceed $5,000 once the aggregate threshold is crossed. Use this list to complete Form 3520 Part IV accurately.

How the $5,000 Rule Works

1. Step 1: Determine if your aggregate foreign gifts exceed the $100,000 individual or $20,573 corporate threshold.
2. Step 2: If the threshold is crossed, review each individual gift you received from foreign donors.
3. Step 3: For each gift valued at $5,000 or more, list it separately on Form 3520 Part IV, line 54 with the donor name, amount, and date.
4. Step 4: Gifts under $5,000 are combined into a single total and reported in aggregate on the same line.

What Counts as a "Gift" for Itemization?

• Cash or currency — The full USD value on the date received
• Property — The fair market value (FMV) on the date received
• Securities or stock — The FMV on the date received
• Cryptocurrency — The FMV in USD on the date received
• Real estate — The FMV on the date received (appraisal recommended)
• Forgiveness of debt — The amount of debt forgiven by a foreign party

Example: Itemization in Action

Total gifts from related parents exceed $100,000. Gifts over $5,000 must be listed individually. Gifts under $5,000 are aggregated and reported as a single total.

Related Donors: Who Counts for Aggregation?

Related-party aggregation is the most misunderstood rule on Form 3520. For threshold purposes, you must combine gifts from donors who are related to each other — not donors who are related to you.

The aggregation rule requires you to combine gifts from donors who are related to one another under IRC § 267(b). This means if your parents (who are married) both give you gifts, their gifts are aggregated into a single total. The definition of "related" is specific and does not include all family members.

Related Parties — Defined (IRC § 267(b))

The following relationships require aggregation:

How Aggregation Works — Step by Step

1. Identify all foreign donors who gave you gifts in the tax year.
2. Determine the relationship between each pair of donors.
3. Group donors who are related to each other (spouses, parents/children, siblings, etc.).
4. Sum all gifts within each related group.
5. Compare each group's total against the $100,000 individual threshold.
6. If any group exceeds $100,000, you must file Form 3520.
7. Unrelated donors are checked individually against $100,000.

Form 3520 Penalties: What You Need to Know

The penalty for failing to file Form 3520 is 5% of the gift amount per month, capped at 25% of the total gift value. This means if you file late, the penalty can reach up to one-quarter of the gift amount — even when no tax is owed. In 2025, the IRS announced they will no longer automatically assert these penalties, but they can still be imposed if you lack reasonable cause.

The penalty applies to the total value of the gifts that triggered the filing requirement. For example, if you received $100,000 in foreign gifts and file 5 months late, the penalty could be $25,000 (5% × 5 months = 25% × $100,000). The penalty is capped at 25% regardless of how many months late you file.

Penalty Calculation — Month by Month

2025 IRS Policy Change — No More Automatic Penalties

In 2025, the IRS changed its enforcement approach for Form 3520 penalties. The agency announced it will no longer automatically assert the 5% per month penalty against taxpayers who are not willfully avoiding reporting. However, this does not mean penalties are eliminated — they can still be imposed if the IRS determines you lack "reasonable cause."

Key takeaways from the IRS policy shift:

• Automatic penalties are suspended — The IRS will no longer automatically apply the 25% penalty in every case.
• Reasonable cause is now more important — If you can demonstrate a good-faith effort to comply, penalties may be abated.
• Willful non-compliance is still penalized — If the IRS determines you knowingly failed to file, the full penalty can still apply.
• Filing late is still better than not filing — Even with the policy change, filing late demonstrates good-faith compliance.

How to Fight Form 3520 Penalties — Reasonable Cause Defense

If the IRS asserts a Form 3520 penalty against you, you can fight it by demonstrating reasonable cause. This means showing that you exercised "ordinary business care and prudence" but still failed to file on time. The IRS considers factors such as:

• Your knowledge and experience — Were you a first-time filer or a sophisticated taxpayer?
• Reliance on a professional — Did a CPA or tax attorney provide incorrect advice?
• Documentation efforts — Did you attempt to gather the necessary information but were delayed?
• Good-faith compliance — Have you been compliant in prior years?
• Prompt filing after discovering the requirement — Did you file as soon as you became aware?

If you face a penalty, consider working with a tax professional experienced in international reporting. The cost of professional representation is often far less than the penalty amount.

Filing Deadlines: April 15 vs. June 15 vs. October 15

Form 3520 is due by April 15 for most U.S. taxpayers. If you are a U.S. citizen or resident living abroad, the due date is June 15. You can request an extension to October 15 by filing Form 4868 (the same extension form used for your income tax return).

Form 3520 cannot be filed electronically — it must be mailed to the IRS. This is a common source of confusion because most tax forms can now be e-filed. Plan ahead to ensure your paper filing is mailed by the deadline.

Deadline Rules at a Glance

Filing Addresses — Where to Mail Form 3520

The mailing address for Form 3520 depends on your state of residence. Use the addresses below — note that the addresses differ from the standard income tax return addresses.

Source: IRS Form 3520 Instructions. Confirm your correct mailing address before filing, as addresses can change. The IRS website has the most current information.

What If You Missed the Deadline?

If you missed the Form 3520 filing deadline, file as soon as possible. The penalty clock stops when the IRS receives your filing. Filing late is always better than not filing at all.

Consider these options if you're filing late:

• File immediately — Include a statement explaining why you're filing late
• Reasonable cause statement — Explain the circumstances that caused the delay
• Streamlined filing procedures — If you're an expat or offshore filer, you may qualify for reduced penalties under the IRS streamlined programs
• Work with a professional — International tax attorneys and CPAs can help you navigate late filing without triggering penalties

How to Track Gifts by Donor: A Step-by-Step System

No competitor provides a practical system for tracking gifts by donor. This section gives you a complete methodology that works alongside the tracker above. Follow these steps to ensure you never miss a filing requirement.

Step 1: Identify Every Foreign Donor

Start by listing every foreign person or entity that gave you a gift in the tax year. Create a separate record for each donor with these details:

• Full name — As it appears on any documentation
• Relationship to you — Parent, sibling, friend, business associate, etc.
• Donor type — Individual, corporation, partnership, or estate
• Country of residence — For currency conversion and documentation
• Contact information — In case you need to verify details later

Step 2: Record Every Gift with Date and Value

For each donor, record each gift you receive. This is the most important step for accurate threshold tracking.

• Date received — The day the gift was given to you (not when you deposited it)
• Amount — The value in the currency received
• USD equivalent — Convert using the exchange rate on the date of receipt
• Description — Cash, check, wire transfer, property, stock, etc.
• Form of transfer — Cash, bank transfer, property deed, etc.

Step 3: Aggregate Related Parties

Identify which donors are related to each other. Use the relationship definitions from IRC § 267(b) to determine aggregation.

Aggregation decision tree:

Once you've identified related groups, sum the gifts from each group. This total is what you compare against the $100,000 threshold. The tracker above does this automatically when you select relationships.

Step 4: Check Both Thresholds Separately

Run two separate threshold checks for every tax year:

1. Individual threshold test: For each related group and each unrelated individual, check if the total exceeds $100,000.
2. Entity threshold test: Sum all gifts from foreign corporations and partnerships. Check if the total exceeds $20,573.

If either test shows you're over the threshold, you must file Form 3520. The tracker above runs both tests automatically and shows your status in real-time.

Step 5: Determine If You Must Itemize Individual Gifts

If the aggregate threshold is crossed, review each gift you received. For every gift valued at $5,000 or more, you must list it separately on Form 3520 Part IV, line 54. Gifts under $5,000 are aggregated.

Create a separate list of all gifts over $5,000 with:

• Donor name
• Date received
• Amount in USD
• Brief description

This is exactly the format required on Form 3520. The tracker above flags which gifts need itemization when you run the calculation.

Step 6: Document Everything

Maintain records to support your tracking:

• Bank statements — Showing incoming transfers from foreign accounts
• Gift letters or emails — Written documentation from the donor
• Currency conversion records — Exchange rates used and sources
• Property appraisals — For non-cash gifts (real estate, art, securities)
• Form 3520 copy — Keep a copy of your filed form

The tracker above automates steps 1-5. Use it to maintain your records and check your status at any time.

Other IRS Forms You May Need to File

If you receive foreign gifts, you may also need to file other international information returns. These are separate requirements with different thresholds and deadlines.

Note: Each form has independent filing requirements. Filing Form 3520 does not satisfy FBAR or FATCA obligations, and vice versa. Consult a tax professional to determine all your filing obligations.
