Putting money into your own company can be a reportable transfer

The colonnade of a neoclassical federal building at dusk, illustrating Form 926: funding a UK company
An American in London capitalizes the UK company she just set up. No gain, no income, nothing to tax. There is still a form, and missing it keeps the year open.

Form 926 is the filing people discover a year late. An American living in London sets up a UK limited company and puts money in to get it trading. Nothing is sold, nothing is earned, and no tax is due on the movement.

That last point is what misleads. The reporting rule does not follow the tax. It follows the transfer.

So a capital injection into your own company can be reportable even though it changes nothing about what you owe. Cash is property for this purpose, and the thresholds are lower than people expect.

The consequences of missing it are worse than the form deserves. There is a percentage penalty rather than a flat one, and the limitation period for the year stops running until the information arrives.

So this guide covers who files, what the cash rule actually says, the exceptions that survive, and what the repeal of the business exception changed for anybody moving assets rather than money.

What is Form 926?

A reporting return for transfers of property to a foreign corporation. Form 926 reports transfers described in the relevant Code sections, and its purpose is disclosure rather than computing a liability.

So it is an information return. It tells the IRS something happened, and it is filed with your return.

Who has to file it?

US citizens and residents file it, and so do domestic corporations, estates and trusts. The instructions set out that list, and the first entry catches a great many people living abroad.

So American citizenship is enough. Living in London and running a British company does not take you outside the rule.

Partnerships work differently. Where a partnership transfers, the domestic partners file rather than the partnership, each treated as transferring a proportionate share.

So check citizenship before anything else. Form 926 follows the person rather than the place they happen to live.

Why cash catches people

Because nobody thinks of money as property being transferred. You are funding your own company, not disposing of anything, and no gain arises anywhere.

The rule does not care. A US person transferring cash to a foreign corporation reports it where either of two tests is met.

Those two tests sit at a lower level than most founders assume. Ordinary working capital clears them easily.

So treat every injection as a potential filing. Form 926 does not wait for a gain to appear.

The two cash tests

The first looks at ownership immediately after. You report where a tenth or more of the company then belongs to you, measured either by voting power or by value, and counting indirect holdings.

The second looks at the amount. You report where cash transferred to that corporation during the twelve-month period ending on the date of the transfer comes to more than $100,000.

Note the word or. Either test on its own brings the transfer inside the rule, so a sole shareholder funding a company meets the first whatever the sum.

Record the date of each payment. Both tests turn on when, not only on how much.

Does the twelve months follow the tax year?

No, and that is the detail that trips people. The period runs for twelve months ending on the date of the transfer, which is a rolling measure rather than a calendar or tax year.

So several modest injections can aggregate. Three payments of forty thousand dollars across eleven months reach the threshold, even though no single one comes close.

So keep a running total rather than an annual one. The window moves with every payment you make.

What value do you report?

Whatever the property was worth on the day it moved, which is the same measure the penalty uses. For cash that is simply the amount, and for anything else somebody has to establish it.

So keep the valuation working papers with the filing. The form asks you to state a figure, and the exposure scales directly with it.

What the penalty actually is

A percentage, not a fixed sum, which is what makes it serious. Failing to comply costs a tenth of whatever the property was worth on the day it moved.

A cap applies, and an exception sits alongside it. The penalty is limited to $100,000 unless the failure was due to intentional disregard, and it does not apply where the failure was due to reasonable cause and not willful neglect.

So the exposure scales with what you moved. A large capitalization produces a large number very quickly.

So the arithmetic rewards filing late over not filing at all. A late Form 926 still starts the clock running.

The part that outlasts the penalty

An unfiled form keeps the year alive. Where the required information is not provided, the period of limitations for assessing tax on that transfer extends to three years after the information is eventually supplied.

Read that carefully. The clock does not start until you file, so a transfer from years ago can still sit inside an open window.

In our practice that consequence worries clients far more than the penalty does, and reasonably so.

  1. List every movement of cash or property into the foreign company for the year.
  2. For each one, look back twelve months and total the cash transferred.
  3. Check your holding immediately after each transfer against the 10% test.
  4. Establish the fair market value of any non-cash property at the transfer date.
  5. Check whether a listed exception genuinely applies before concluding you need not file.
  6. File with the return for the year, and keep the valuation working papers.

There is a second penalty too

A separate provision addresses the tax rather than the reporting. A 40% penalty may apply to an underpayment resulting from an undisclosed foreign financial asset understatement.

It has its own defense. No penalty applies to a portion of an underpayment where the taxpayer shows reasonable cause and acted in good faith on that portion.

What changed for property after 2017

What changed for property after 2017 — Form 926
From our guide to Form 926: funding a UK company.

The escape route closed. Legislation repealed the active trade or business exception, so transfers occurring after 2017 no longer rely on it.

The consequence is substantial. Transfers of tangible property, other than certain stock transfers, fall under the general rule and attract full gain recognition.

So moving business assets into a UK company is a taxable event rather than a neutral reorganization. Moving cash is not taxable, but it is still reportable.

So value the assets before moving them. The tax consequence arrives whether or not anybody expected it.

Which exceptions survive?

Several of them, and they are specific rather than general in nature. A US person need not file for certain exchanges, including where they exchange stock of a foreign corporation in a recapitalization.

Another covers asset reorganizations. Exchanging stock of a domestic or foreign corporation for stock of a foreign corporation under a qualifying asset reorganization can fall outside, where it is not treated as an indirect stock transfer.

A further exception turns on size. A transferor of stock or securities can be outside the requirement where they owned less than 5% of both the total voting power and the total value of the transferee.

Check each one against your own facts. They are drafted narrowly, and none of them is a general let-out.

Can spouses file one form?

Yes, on a single condition that is either easy to satisfy or easy to miss entirely. Spouses may file Form 926 jointly, but only where they file a joint income tax return.

So the filing status drives it. Couples filing separately, which is common where one spouse is not American, each handle their own transfers.

How it sits with the other company forms

It reports an event, while the others report a year. Form 926 covers the transfer itself, and the annual position goes elsewhere.

A US owner of a foreign corporation usually meets Form 5471 for the ongoing reporting, which our guide to Form 5471 and a UK company covers.

So the two run alongside each other. Filing one does not discharge the other.

Does an entity election change anything?

It can change what America sees, and therefore whether a transfer to a foreign corporation has happened at all. Classification decides whether there is a corporation on the receiving end.

Our guide to the entity classification election covers how a UK company is classified and when you can change it. Settle that question before working through the reporting.

What if it is not a corporation?

Then this may well not be the right form at all, because it reports transfers made to a foreign corporation specifically. Classification decides which reporting regime you are in, and it has to be settled first.

A foreign partnership carries its own reporting instead, and our guide to Form 8865 covers that. Settle the classification first and the form follows from it.

What the underlying regulation says

The detail sits in the regulations rather than the form. Regulation 1.6038B-1 contains the reporting rules, including the cash provision the instructions point to.

So go there when the instructions seem ambiguous. The form summarizes, and the regulation governs.

An illustrative example

Take an illustrative case. An American living in London incorporates a UK company, owns all the shares, and pays in 60,000 dollars in March and a further 70,000 in October.

Neither payment alone exceeds the cash threshold. Looking back twelve months from October, though, the total reaches 130,000 dollars.

The ownership test was met from the first day in any event, since she holds the whole company. Two reportable transfers, and the year stays open until the form arrives.

Notice that no tax arose on either payment. The filing duty was never about tax in the first place.

Common mistakes we see

The commonest is treating cash as outside the rule. It is property for this purpose, and the instructions address it directly.

The second is counting against the tax year rather than the rolling twelve months ending on the transfer date.

After those comes the belief that no tax means no filing. The reporting duty attaches to the transfer, and the penalty attaches to the failure.

A fourth is assuming a small company is too small to matter. Form 926 sets no minimum at all for the ownership test.

How US UK Tax Hub helps with Form 926

First we map every movement into the company across the year, because the rolling window means the dates matter as much as the amounts. Then we test each one against both cash rules.

Where a filing was missed, we look at reasonable cause before anything else. Start with our US federal returns service, or reach us through our contact page.

Questions this raises for readers

Yes, where either test is met. A US person reports a cash transfer to a foreign corporation where, straight afterward, a tenth or more of it belongs to them by voting power or by value. The same applies where cash moved in the twelve months ending on that date exceeds $100,000. No gain or income is needed for the duty to arise.


It ends on the date of the transfer and runs back twelve months from there. That is a rolling period rather than a tax year, so separate injections can aggregate across a year end. Three payments well under the threshold can combine into one that exceeds it.


Two things. The penalty takes a tenth of whatever the property was worth on the day it moved, capped at $100,000 unless the failure was due to intentional disregard. Separately, the assessment period for tax on that transfer extends to three years after the information is finally provided, so the year stays open.


Yes. The penalty does not apply where the failure to comply was due to reasonable cause and not to willful neglect. That is worth establishing properly rather than asserting, because the cap on the penalty disappears entirely where the failure was due to intentional disregard.


Not for transfers after 2017. Legislation repealed that exception, and transfers of tangible property other than certain stock transfers now fall under the general rule with full gain recognition. Moving operating assets into a foreign company is therefore a taxable event rather than a neutral step.


Not necessarily. Spouses may file one form jointly, but only where they file a joint income tax return. Where they file separately, which is common when one spouse is not a US person, each deals with their own transfers on their own return.


The reporting duty has nothing to do with the company's results. It attaches to the transfer of property into the corporation, measured by what you moved and what you hold afterward. A company that trades at a loss, or does not trade at all, changes none of that analysis.
