When Your Parents Send Money: Form 3520 and the Reporting Threshold

The money is not the problem. The silence is.

The Down Payment

Your parents want to help with the house. They have been saving for years with something like this in mind, and now you are buying in a city where the deposit is a number they find hard to believe. So they wire it.

Or you get married and the customary gifts from both families arrive at once. Or a grandparent dies and a share of a modest estate abroad reaches you months later.

None of this feels like a tax event. It is family money, moving between people who love each other, arising from a life that has nothing to do with the United States. In every emotional sense it is entirely private.

It is also, past a certain size, a U.S. filing obligation.

The Gift Is Not Taxable

Start here, because most people arrive at this topic with the wrong fear.

A gift you receive from a foreign individual is generally not income to you. You do not add it to your return. You do not pay U.S. income tax on it. The same is generally true of an inheritance from a family member abroad. And U.S. gift tax is a tax on the giver, not the recipient — a parent who is not a U.S. person, giving assets located outside the United States, is generally outside its reach.

So the amount you owe on a genuine gift from your parents abroad is, in the ordinary case, nothing.

What is required is disclosure. The U.S. wants to know that a large sum arrived from abroad and what it was. That is the whole of the obligation: a form, filed on time, reporting an amount you do not owe tax on. Form 3520 is that form.

(One caveat worth stating plainly: it must actually be a gift. Money that is really payment for work you did, or a distribution from a foreign trust or company rather than from a person, is a different question with a different answer.)

The Threshold

Reporting is required once gifts from a nonresident individual exceed a set dollar threshold in a calendar year. The current figure is published in the Form 3520 instructions, and it is high enough that ordinary support from family does not come near it.

Two features of the threshold catch people out.

Gifts aggregate across the year. It is not tested transfer by transfer. Three payments in March, July, and November are added together and compared to the threshold once.

Gifts aggregate across related donors. Your father and your mother are related parties. So is a grandparent, in most family situations. Two transfers, one from each parent, each comfortably below the line, can cross it jointly. This is the single most common way people miss the requirement: each individual amount looked unremarkable, and nobody added them up.

Separately, gifts from foreign entities — a company or a partnership rather than an individual — carry a much lower threshold, adjusted annually. If money arrives from a family business rather than a family member, treat that as a different question.

The Penalty

Here is why this small form matters so much.

The penalty for failing to report a reportable foreign gift is calculated as a percentage of the amount received, accruing while the failure continues, up to a substantial fraction of the gift. On money that was never taxable in the first place.

Set the two sides next to each other, because the asymmetry is the entire point:

Reporting it costs you a form. Form 3520 is not attached to your 1040 — it is filed on its own, mailed to the IRS service center in Ogden, Utah, and only its due date tracks your return. Tax owed: none.
Not reporting it can cost a meaningful fraction of a gift your parents spent a working life accumulating.

There is no version of this where staying quiet is cheaper. It is one of the highest-return pieces of paperwork in the U.S. tax system.

Where It Gets More Complicated

Not everything that looks like a gift is one.

Some home-country structures — family holding arrangements, certain foundations, some inheritance and succession vehicles, and a number of retirement and education savings products — are treated as foreign trusts under U.S. rules, even when nobody involved has ever used the word "trust". Money coming out of one of those is not a gift from an individual. It is a distribution from a trust.

That changes the regime substantially. Trust reporting brings Form 3520-A alongside Form 3520, obligations that can fall on you as an owner or beneficiary rather than only as a recipient, and its own penalty structure. Narrow relief exists for certain tax-favoured foreign retirement and savings arrangements, but it is conditional and does not reach everything.

If the money came from an arrangement rather than from a person, that is worth establishing before you file, not after.

The Paper Trail

Practical habits that cost nothing at the time and are invaluable later:

Keep the wire records. The sending bank's confirmation, the receiving statement, and the dates. Reconstructing a transfer from four years ago is unpleasant.
Get a short note from the donor. Two or three sentences from your parents saying what the money is, that it is a gift, that no repayment is expected, and when it was sent. An email is fine. Its value is that it exists and is contemporaneous.
Expect your bank to ask questions. A large inbound international transfer may prompt a call, a form, or a request for the source of funds. This is anti-money-laundering monitoring, required of the bank and applied to everybody. It is not a tax enquiry and it is not the IRS. The two get conflated constantly, and the conflation causes a great deal of unnecessary fear.

If You Already Received One and Did Not Report It

This happens often, for the most ordinary reason: nobody told you. The gift was not taxable, so it never came up when the return was prepared, and nobody asked whether family abroad had sent money.

Late Form 3520 filings are commonly made with a reasonable cause statement — a plain explanation of what happened and why the form was not filed on time. Reasonable cause is a real standard with a real record of being accepted, and there are established procedures for submitting delinquent international information returns. As with most of this, correcting it yourself, before anyone asks, is treated very differently from having it found.

If a transfer is sitting unreported, or one is on its way and you would rather get it right the first time, our foreign asset reporting work covers exactly this.
