Pro forma Form 1120

A near-blank Form 1120 filed by foreign-owned single-member LLCs as the filing vehicle for Form 5472.

Definition

Pro forma Form 1120 is a Form 1120 filed by foreign-owned single-member US LLCs that are treated as disregarded entities. The form is mostly blank (no income tax computation) and exists solely to provide a vehicle for the attached Form 5472. Required by Treas. Reg. § 1.6038A-1(c).

Context

Pro forma Form 1120 is filed annually with Form 5472 by April 15. Filing Form 5472 alone without the pro forma Form 1120 is not compliant.

Example

A Bangladeshi founder's single-member Delaware LLC files Form 5472 + pro forma Form 1120 each April 15. The pro forma Form 1120 has the LLC's name, EIN, address, and tax year. Most income/deduction lines are blank or marked N/A.

Common pitfalls

Treating the pro forma Form 1120 as a full corporate return is wrong; it is a different filing.
CPA fees for Form 5472 + pro forma Form 1120 typically run $200-$500 per year.

What pro forma actually means in this filing

The phrase pro forma is Latin for as a matter of form, and that meaning is the whole point of this filing. When a foreign-owned single-member Delaware LLC submits a pro forma Form 1120, it is not reporting corporate income, computing a tax liability, or claiming deductions in the way a real C corporation would. The LLC is a disregarded entity for federal income tax purposes, which means the IRS does not see it as a taxpayer separate from its single foreign owner. So why use a corporate income tax form at all? Because the IRS needed an existing document to carry the real attachment, Form 5472, and the regulations chose Form 1120 as that carrier.

In practice the pro forma Form 1120 is a cover sheet with identity information rather than a financial statement. It shows the LLC's legal name, its Employer Identification Number, its mailing address, and the tax year being reported. The income and deduction lines that dominate a normal corporate return stay blank or get marked as not applicable. The written instruction from the IRS is to enter the words Foreign-owned U.S. DE across the top of the form so that a person processing it understands immediately that this is a disregarded entity filing and not a genuine corporate tax return.

Understanding this distinction early saves a non-resident founder a lot of anxiety. Seeing the words corporate income tax return on the form can make a single-member owner assume they suddenly owe corporate tax or have to elect C corporation status. Neither is true. The pro forma copy exists only to give Form 5472 a recognized place to live in the IRS filing system, and it does not change how the LLC's profits are taxed.

Why the IRS requires it at all

Before 2017, foreign-owned single-member US LLCs that were disregarded entities often had no federal filing obligation if they earned no US-source income. That created a transparency gap. A non-resident could form a US LLC, move money through it, and leave almost no federal paper trail because the entity was invisible for income tax and had no separate return. Treasury closed that gap by reclassifying these disregarded entities as domestic corporations for the limited purpose of the reporting and record-keeping rules under section 6038A.

That reclassification is narrow and deliberate. It does not turn the LLC into a real corporation for income tax. It only borrows the corporate reporting machinery so that the entity becomes a reporting corporation that must disclose certain transactions with its foreign owner and related parties. The disclosure happens on Form 5472. Because Form 5472 was designed as an attachment to a corporate return rather than a standalone document, the IRS requires it to ride along with a Form 1120. The pro forma version is how a disregarded entity satisfies that structural requirement without pretending to be a taxpaying corporation.

The legal anchor is Treasury Regulation section 1.6038A-1(c), which extends the reporting corporation definition to these foreign-owned disregarded entities. This is general information rather than legal advice, but the practical takeaway is consistent across the guidance: the pro forma Form 1120 and Form 5472 are two halves of a single annual compliance act, and the corporate form is the vehicle, not the substance.

How it applies to a single-member foreign-owned LLC

If you are a non-resident who owns 100% of a Delaware LLC and you have not filed an election to be taxed as a corporation, your entity is a foreign-owned single-member disregarded entity by default. That single sentence determines your filing path. You are the exact taxpayer profile the pro forma Form 1120 plus Form 5472 requirement was written for. It does not matter whether the LLC made a profit, lost money, or sat dormant with only a bank account. The reporting obligation is triggered by reportable transactions with related parties, and those transactions include things as basic as the capital you contributed to start the company.

Many founders are surprised that funding their own company counts. When you wire money from your personal account abroad into the LLC's US bank account to capitalize it, that movement between you and the entity is a reportable transaction between the foreign owner and the reporting corporation. The same applies when the LLC distributes money back to you, or when it pays you, or when a related company you also control transacts with the LLC. These flows get summarized on Form 5472, and the pro forma Form 1120 carries that 5472 to the IRS.

This is why the filing applies even to a first year LLC that has not yet earned a single dollar of revenue. The act of forming the company, opening the account, and putting in startup capital can be enough to create the duty to file. A non-resident owner should plan from day one to file the pair every year, rather than assuming the obligation begins only once the business becomes profitable.

A worked example: a quiet first year

Consider a founder in Bangladesh who forms a Delaware LLC by paying the $110 Certificate of Formation fee, obtains a free EIN by filing Form SS-4 (which usually takes about 8 to 10 business days when the application has no SSN), and opens a US business account with a provider like Mercury or Wise. They wire $2,000 from their personal account to capitalize the LLC. The company spends the year building a product and earns no revenue. On the surface nothing taxable happened, and a beginner might assume there is no filing to do.

The reality is different. The $2,000 capital contribution is a reportable transaction between the foreign owner and the disregarded entity. The LLC must file Form 5472 reporting that contribution, and it must attach the 5472 to a pro forma Form 1120. The 1120 carries the company name, the EIN, the Delaware address, and the calendar tax year. Across the top the preparer writes Foreign-owned U.S. DE. The income and deduction lines are blank or marked not applicable. Part of Form 5472 records the founder as the 25% foreign owner and lists the contribution amount.

The cost of this in a quiet year is mostly time and modest preparer fees rather than tax. A CPA handling Form 5472 plus the pro forma Form 1120 typically charges in the range noted for this entry, roughly $200 to $500 per year. The lesson is that a year with no profit is still a filing year, and skipping it because nothing seemed to happen is one of the most common and most expensive mistakes a non-resident founder makes.

A worked example: an active trading year

Now picture the same founder a year later. The LLC has paying customers, collects revenue through Stripe into its Mercury account, pays software subscriptions, and at year end the owner draws $15,000 out to their personal account abroad. There were several flows between the owner and the entity over the year: an additional $3,000 capital top-up early on, the $15,000 distribution at year end, and a payment the LLC made to a separate company the founder also owns in their home country.

Each of these owner and related-party flows is summarized on Form 5472. The reportable amounts are reported in the relevant parts of the 5472, and the pro forma Form 1120 again serves only as the carrier with identity details. Importantly, the customer revenue itself is not reported as corporate income on the pro forma 1120, because the LLC is still a disregarded entity and the 1120 is not a real income tax computation. Whether and where that business income is actually taxed depends on the owner's own tax situation, US-source income analysis, and any treaty, which is a separate question from this reporting filing.

This example shows the dividing line clearly. The pro forma Form 1120 plus Form 5472 is an information report about money moving between the foreign owner and the entity and its related parties. It is not the place where business profit is taxed. A founder who confuses the two may either overstate things on the wrong form or, worse, assume the 5472 filing replaces any personal tax analysis they may owe. The two analyses are distinct and both deserve attention.

How it connects to formation and getting started

The duty to file this pair flows directly out of the formation steps a non-resident already completes. Filing the Certificate of Formation with Delaware for $110 creates the legal entity. Applying for an EIN through Form SS-4, which is free and usually issued in about 8 to 10 business days for applicants without an SSN, gives the LLC the federal identification number that the pro forma Form 1120 and Form 5472 both require in their identity fields. Without an EIN you cannot complete either form, so the EIN step is a prerequisite for the entire compliance chain.

The formation choices also lock in which filing path applies. A single-member LLC that takes no corporate election lands on the pro forma Form 1120 plus Form 5472 route described in this entry. If instead the LLC had multiple members, it would generally file a partnership return rather than a 5472. And if the owner elected C corporation taxation, the entity would file a genuine, fully completed Form 1120 with an actual tax computation rather than a near-blank pro forma copy. So the structure you pick at formation determines the form you live with each year.

For a typical non-resident founder forming a single-member Delaware LLC, the practical sequence is: pay the $110 formation fee, get the free EIN, open a US bank account, capitalize the company, and then mark the calendar for the annual pro forma Form 1120 plus Form 5472 filing. Treating these as one connected workflow, rather than separate surprises, is how founders avoid scrambling at deadline time.

How it connects to banking and recordkeeping

Banking is where most of the reportable transactions on Form 5472 actually originate, which makes the bank account the center of gravity for this filing. When a founder funds the LLC through Mercury, Wise, Relay, Lili, or Payoneer, the incoming capital wire is a reportable owner contribution. When the LLC sends money back to the owner, that distribution is reportable too. Because the pro forma Form 1120 carries the 5472, keeping clean banking records all year is what makes the annual filing straightforward instead of a reconstruction exercise.

A practical habit is to label every transfer between the owner and the LLC at the moment it happens. Note the date, the amount, the direction, and whether it was a capital contribution, a distribution, a loan, or a payment. Keep these separate from ordinary business income and expenses, because the 5472 cares specifically about owner and related-party flows, not about routine customer revenue or vendor payments. The regulation underlying this filing also imposes record-keeping duties, so retaining bank statements and a simple ledger is part of compliance, not just good hygiene.

Mixing personal and business money makes this filing much harder and can blur the very line the form is meant to capture. A founder who runs personal expenses through the LLC account, or who moves money in and out without records, will struggle to identify what is reportable. Maintaining a dedicated business account with one of the named providers and treating it strictly as the company's money keeps the annual pro forma Form 1120 and Form 5472 exercise manageable.

The annual deadline and what late looks like

The pro forma Form 1120 with the attached Form 5472 is filed annually, and for a calendar-year LLC the due date is April 15 following the end of the tax year. Filing the Form 5472 by itself, without the pro forma Form 1120 wrapped around it, is not considered compliant. The two are a unit. Equally, sending in a pro forma Form 1120 with no 5472 attached defeats the purpose, because the whole reason the corporate form is used is to deliver the 5472. Treat them as inseparable.

The penalty exposure for getting this wrong is significant and is the main reason founders take the filing seriously. The statutory penalty associated with failing to file Form 5472, or filing it substantially incomplete or late, is $25,000. That penalty can apply even when the LLC earned nothing and owed no tax, because it is a reporting penalty rather than a tax penalty. The amount does not scale down for a small or dormant company, which is why a quiet first year still warrants a timely, complete filing.

If a deadline is missed, the situation is not automatically hopeless, but it does call for prompt attention rather than avoidance. There are recognized procedures for late and reasonable-cause situations, and a qualified preparer can advise on the specific path. This entry is general information and not tax advice, so a founder facing a missed or incomplete filing should consult a professional familiar with foreign-owned disregarded entity reporting rather than guessing at the remedy.

Related terms a founder should know

Several terms cluster around this filing, and keeping them straight prevents confusion. Form 5472 is the actual information return that the pro forma Form 1120 carries. A full Form 1120 is the genuine corporate income tax return that a real C corporation files with a complete tax computation, which is a different animal from the near-blank pro forma copy. A disregarded entity is the tax status that makes a single-member LLC invisible for income tax and routes it onto this reporting path. A single-member LLC is the structure that, when foreign-owned and unelected, lands precisely here.

The EIN connects to this filing as the identifier on both forms, and it is obtained for free through Form SS-4 in roughly 8 to 10 business days for applicants without an SSN. Reportable transaction is the technical trigger that creates the duty to file, covering owner contributions, distributions, loans, and related-party dealings. Reporting corporation is the borrowed status that a foreign-owned disregarded entity takes on solely for these reporting rules. Each of these terms describes one gear in the same machine, and seeing how they mesh helps a founder understand why the filing exists.

It also helps to separate this filing from things that are not part of it. The Delaware franchise tax, a $300 flat amount due each June 1, is a state obligation that has nothing to do with the federal pro forma Form 1120. Beneficial ownership reporting is yet another separate topic. Grouping every annual obligation into one mental bucket is a common error, and untangling them makes each one easier to handle on its own schedule.

Edge cases: dormant, dissolved, and partial years

A dormant LLC that did nothing all year still has to think about this filing, because the trigger is reportable transactions rather than business activity. If even one owner contribution or distribution touched the account during the year, the 5472 and its pro forma 1120 are generally required. The cleanest edge case is an LLC with truly zero owner and related-party transactions for the entire tax year, where the reporting obligation may not arise, but founders should confirm that with a preparer rather than assume it, because the capital that started the company often counts.

Dissolution creates its own timing question. If a founder closes the LLC partway through a year, there is typically a final-year filing covering the period the entity existed, including any final distributions of remaining funds back to the owner. Walking away from a US LLC without formally dissolving it and without handling the final reporting can leave open obligations and franchise tax accruals behind, so closing the company properly matters as much as opening it. A short or partial tax year is reported as such on the forms, with the correct dates in the identity section.

Another edge case is a change in ownership or structure during the year. If the LLC adds a second member and becomes a partnership, or if the owner makes a corporate election, the filing path can shift mid-stream, sometimes producing a split year with different forms for different periods. These transitions are exactly the moments to get professional input, because the right combination of forms depends on the specific dates and elections. This is general information and not advice tailored to any one situation.

Common misunderstandings

The single most common misunderstanding is believing that the pro forma Form 1120 means the LLC owes corporate income tax. It does not. The form is near-blank precisely because it is not computing any tax. A related misunderstanding is thinking that filing this form is the same as electing C corporation status. It is not an election and changes nothing about how the entity is taxed. The disregarded entity remains disregarded for income tax, and the pro forma copy is merely a delivery wrapper for Form 5472.

Another frequent error is assuming the filing only applies once the business makes money. As the quiet-first-year example showed, the obligation can arise from capital contributions alone, so a profitless or even revenue-free year is still a filing year. Founders also sometimes believe a registered agent or formation service automatically handles this federal filing as part of their package. Agent and formation services usually cover state matters and the formation paperwork, not the annual federal 5472 and pro forma 1120, so a founder should confirm exactly who is responsible rather than assume coverage.

A final misunderstanding is conflating this federal filing with the Delaware franchise tax. The $300 flat franchise tax due June 1 is a state obligation and is entirely separate from the April 15 federal pro forma Form 1120 and Form 5472. Paying one does not satisfy the other. Keeping the federal information filing and the state franchise tax on distinct mental tracks, with distinct deadlines, is how founders avoid missing one while attending to the other.

Practical preparation and getting help

Preparing this filing well starts long before April 15. Throughout the year, keep a running record of every transfer between you and the LLC and between the LLC and any other company you control. Note the EIN somewhere accessible, since both forms need it, and keep the Delaware formation documents and the LLC's mailing address handy for the identity fields. When deadline season arrives, a well-kept ledger turns the pro forma Form 1120 and Form 5472 into a quick assembly job rather than a stressful archaeology project.

Many non-resident founders choose to use a CPA or specialized preparer for this filing, both because the $25,000 penalty raises the stakes and because the forms are unfamiliar to those outside the US tax system. Fees for handling Form 5472 plus the pro forma Form 1120 commonly fall in the range cited in this entry, roughly $200 to $500 per year, depending on the complexity of the transactions. A founder with very simple flows and good records can sometimes prepare the forms themselves, but reviewing the IRS instructions carefully is essential before doing so.

Whichever route a founder takes, the goal is a complete and timely filing every year the LLC exists and has reportable transactions. Pair it with the separate state obligations, such as the $300 franchise tax due June 1, on their own schedules, and keep the federal and state duties from blurring together. This material is general information about how the pro forma Form 1120 works for a foreign-owned single-member Delaware LLC, and a qualified tax professional should be consulted for guidance on any specific situation.

Where this filing sits among other annual duties

A foreign-owned single-member Delaware LLC carries a small set of recurring obligations, and the pro forma Form 1120 with Form 5472 is the federal information piece of that set. The state piece is the $300 flat Delaware franchise tax due each June 1, which keeps the entity in good standing regardless of activity. Maintaining a registered agent in Delaware is a continuing requirement too. These items recur on their own calendars, and a founder who maps them out once tends to handle them smoothly year after year.

It is worth noting one obligation that does not apply here, to avoid wasted effort. Beneficial ownership information reporting under the Corporate Transparency Act was widely discussed, but under the FinCEN Interim Final Rule of March 26 2025, US-formed entities such as a Delaware LLC are exempt from that BOI reporting requirement. So a non-resident founder of a domestic Delaware LLC does not file a BOI report, which removes one item some founders mistakenly expect to handle. The pro forma Form 1120 and Form 5472 remain in place as the core federal filing.

Seeing the full landscape at once helps a founder budget time and money realistically. The recurring costs are modest and predictable: the $300 franchise tax, registered agent fees, and preparer fees for the annual federal information filing. Against the one-time formation outlays, such as the $110 Certificate of Formation and the $297 one-time formation pricing some services charge, these annual duties are the ongoing rhythm of keeping a compliant US LLC. Treating the pro forma Form 1120 as a routine, calendared part of that rhythm is the steadiest way to stay in good standing.
