Convertible note

A short-term debt instrument that converts to equity on specified triggers (typically priced equity round).

Definition

Convertible note is debt that converts to equity at a future priced equity round, typically at a discount and with a valuation cap. Common in seed-stage fundraising. Issuance is a regulated securities offering.

Context

More common with C-corp structure than LLC; LLCs can issue convertible notes via Operating Agreement amendment.

Example

A SaaS LLC raises $250K via convertible notes with $5M valuation cap and 20% discount. Notes convert to equity at next priced round.

Common pitfalls

Securities regulation (Reg D or Reg S) applies.
LLC equity conversion has tax implications.
Convertible notes are debt until conversion; interest accrues.

What a convertible note really does in practice

A convertible note starts its life as a loan. The investor wires money to the company, and on paper the company owes that money back with interest. What makes the instrument different from an ordinary loan is the expectation that almost nobody intends repayment in cash. Instead, both sides agree the debt will turn into ownership at a later moment, usually when the company raises a larger priced equity round and a real per-share or per-unit value has been negotiated. The note is a bridge built to be crossed once, and the crossing point is conversion.

For a non-resident founder running a Delaware entity, the practical effect is that you receive working capital early, before anyone has settled on what the business is worth. That timing is the entire point. Negotiating a precise valuation for a company with little revenue and no track record is slow and contentious, so a note lets you defer that argument while still funding payroll, software, or a first product build. The valuation cap and discount, both already described in the core entry, are the tools that protect the early investor from being diluted by their own willingness to take that risk.

It helps to think of the note as a placeholder for equity rather than as financing in the traditional sense. The interest rate is often modest and is calculated to add to the converted amount rather than to be paid in cash. The maturity date exists mostly as a backstop in case no priced round ever happens. Understanding this dual nature, debt today and ownership tomorrow, is the foundation for everything else a founder needs to know about handling the instrument inside a Delaware LLC.

Why founders reach for a note before a priced round

The most common reason a founder chooses a convertible note is speed. A priced equity round requires a negotiated valuation, a full set of investment documents, and often legal counsel on both sides reviewing share or membership-interest terms in detail. A note collapses much of that work. Many early notes are a handful of pages and reuse standard language, which means a founder can close a check in days rather than weeks. For a company burning through its initial runway, that difference can decide whether the business survives long enough to reach its next milestone.

A second reason is leverage over valuation. When a company is very young, founders frequently believe the business will be worth far more in six to twelve months once a product ships or early customers sign on. Setting a price today would lock in a low number and hand away more ownership than necessary. By deferring the price to a future round, the founder bets that the company will be worth more then, and the note holder accepts that bet in exchange for the cap and discount. Both sides are trading certainty for optionality.

A third reason, particularly relevant for non-resident founders, is that notes can be raised from a small, dispersed group of supporters who already know the founder. An early note round often draws on personal networks, former colleagues, or angels in the founder's home country. Because the mechanics are simpler than a full equity round, it is easier to bring in several smaller checks without coordinating a single closing. The simplicity that makes notes attractive, however, does not remove the securities obligations described elsewhere in this entry, and a founder should treat every dollar raised as a regulated transaction.

How the instrument interacts with a single-member foreign-owned LLC

The core entry already notes that convertible notes are more common with a C-corporation than with an LLC, and that an LLC can issue them through an Operating Agreement amendment. For a single-member foreign-owned LLC, that observation has sharp consequences. A single-member LLC by definition has one owner. The moment a note converts into equity, the company gains a second member, and the entity stops being a single-member LLC for tax purposes. That transition is not a small administrative footnote. It changes the federal tax classification of the company.

By default, a domestic single-member LLC owned by a foreign person is a disregarded entity that files Form 5472 along with a pro forma Form 1120, where the missed or late filing carries a $25,000 penalty. When a second member arrives through conversion, the default classification flips to a partnership, which carries an entirely different return, partnership-level reporting, and withholding considerations on income allocated to foreign partners. A founder who issues notes without planning for this shift can be caught filing the wrong forms in the year conversion happens. The instrument that felt simple at issuance becomes the trigger for a structural change in how the business is taxed.

This is why many advisors steer founders who expect to raise priced equity toward a corporation rather than an LLC from the outset, or toward a conversion of the LLC into a Delaware C-corporation before notes convert. None of this makes a note impossible inside an LLC. It means the Operating Agreement must anticipate new members, the membership-interest classes that conversion will create, and the tax filings that follow. General planning here is information, not legal or tax advice, and the specifics depend on the founder's residency and treaty situation.

A worked example of conversion math

Imagine a non-resident founder forms a Delaware LLC and raises $100,000 on a convertible note carrying a $4,000,000 valuation cap and a 20% discount, with 5% simple interest. Eighteen months later the company raises a priced round at a $6,000,000 pre-money valuation, with new investors paying a price that works out to $1.00 per membership unit. The note now has to convert, and the founder needs to know how many units the original investor receives.

First, interest accrues. Over eighteen months at 5% simple interest, the $100,000 grows by $7,500, so the converting balance is $107,500. Next, the note holder gets the better of the cap price or the discount price. The discount price is 80% of $1.00, which is $0.80 per unit. The cap price is calculated by dividing the $4,000,000 cap by the company's pre-money unit count to get an effective price, and because the round priced the company above the cap, the cap produces a lower per-unit price than the discount does. Suppose the cap price works out to $0.667 per unit. The note holder converts at the lower of the two, $0.667, and receives roughly 161,169 units.

Compare that to a new investor putting in the same $100,000 at the full $1.00 round price, who would receive only 100,000 units. The note holder ends up with about 61% more ownership for the same dollars, which is the reward for taking early risk. For the founder, the lesson is that the cap and discount together determine real dilution, and a low cap on a successful company can transfer far more ownership than the headline loan amount suggests. Running this math before signing, not after, is how founders avoid unpleasant surprises at the conversion table.

Valuation cap and discount, and why they pull in different directions

The valuation cap and the discount are the two levers that decide how a note converts, and they often compete with each other. The discount is the simpler of the two. It gives the note holder a fixed percentage off the price the new round investors pay, rewarding them for committing earlier. A 20% discount means the note holder buys at 80% of the round price no matter how high or low that price turns out to be. It scales with the round and never fully decouples the early investor from the later valuation.

The valuation cap behaves differently. It sets a ceiling on the company value used to convert the note, regardless of how high the priced round values the business. If the company raises at a valuation far above the cap, the cap becomes the dominant term because it can deliver a per-unit price well below even the discounted round price. The cap protects the early investor against the scenario they are betting on, namely that the company becomes much more valuable. When both a cap and a discount exist, standard notes convert at whichever produces more units for the investor, which is usually the lower implied price.

For a founder, the interaction matters because a generous-looking discount can be almost irrelevant if the cap is low and the company performs well. The two terms should be negotiated together, with an eye on the realistic range of future valuations. Setting a cap is effectively naming a soft valuation today, the very thing the note was supposed to defer, so founders sometimes negotiate uncapped notes or notes with only a discount when they have strong leverage. Each choice shifts dilution and should be modeled across several outcomes before agreeing to terms.

Maturity, interest, and what happens if no round arrives

Every convertible note has a maturity date, and most founders treat it as a formality until it is not. The maturity date is the day the loan technically comes due if no qualifying priced round has triggered conversion. Notes commonly run twelve to twenty-four months. If the company has raised its next round before that date, the note simply converts and the maturity clause never bites. The trouble starts when the deadline arrives and the company has neither raised a priced round nor repaid the principal.

At maturity, the note's fallback terms govern. Some notes convert automatically at the cap or at a stated default valuation. Others give the note holder the right to demand repayment in cash, which an early-stage company rarely has on hand. Still others extend automatically or require renegotiation. Because the company is usually short of cash, a maturing note often becomes a pressure point where the investor holds real leverage. A founder who has not read the maturity clause closely can find themselves negotiating from weakness exactly when the business is most fragile.

Interest compounds this dynamic in a small way. Although the rate is usually low and is meant to be added to the converted amount rather than paid in cash, it accrues for the life of the note and modestly increases the investor's eventual ownership or repayment claim. For a non-resident founder, interest paid to a foreign lender can also raise its own tax and withholding questions, which is one more reason to understand the full clause rather than focusing only on the cap and discount. The maturity and interest terms are the quiet parts of the note that decide what happens when the optimistic plan does not unfold on schedule.

Securities law sits underneath every note you issue

The core entry is direct about this, and it deserves expansion because founders routinely underestimate it. A convertible note is a security. Selling it is a securities offering subject to federal and state rules in the United States, and to the rules of any country where an investor resides. The fact that the document is short and the amount is small does not change that classification. The two exemptions most relevant to a small private raise are Regulation D, used for sales to qualifying United States investors, and Regulation S, used for offers made outside the United States.

For a non-resident founder with a Delaware company, both can be in play at once. A founder living abroad who raises from angels in their home country is often operating under Regulation S for those investors, while any United States investor would typically need to fit within a Regulation D exemption, frequently as an accredited investor. Mixing these without care, for example by generally soliciting the offering on social media, can collapse an exemption and turn a routine raise into a compliance problem. The rules are about how the offering is conducted, not only about who ends up holding the note.

None of this is legal advice, and the right path depends on the specifics of each raise and each investor's location. The practical takeaway is that a note should be papered properly, with the exemption identified before money moves, and with records of who was offered the note and on what basis. Founders who treat the note as a casual handshake create a latent liability that can surface years later during a priced round, when sophisticated investors and their counsel review the company's earlier financings during due diligence.

How a note fits alongside formation and the franchise tax

Raising on a convertible note assumes the company legally exists and can enter contracts, which means formation comes first. A Delaware LLC is created by filing a Certificate of Formation, which carries a $110 state fee. Only once the entity is on record can it sign a note, receive funds into its own name, and hold the obligation as a company liability rather than a personal one. A founder who accepts investor money before the entity is formed risks commingling the raise with personal finances, which undermines the liability protection the LLC is supposed to provide.

After formation, the company owes Delaware a flat $300 franchise tax each year, due June 1. This obligation does not pause because a company is pre-revenue or because its only activity so far is a note round. An investor reviewing the company before a later priced round will check that franchise taxes are current, because a delinquent entity can lose good standing, which complicates conversion and any future financing. Keeping the $300 paid on time is a small housekeeping item that protects the value of everything the note is meant to enable.

The note round also intersects with the Operating Agreement, which is the document that governs membership interests. Because conversion will eventually create new members, the Operating Agreement should be drafted or amended to anticipate that event, defining how converted interests are issued and what rights they carry. A founder who closes notes against a bare-bones Operating Agreement may have to renegotiate the entire governance structure under time pressure at conversion. Aligning formation, the franchise tax, and the Operating Agreement early keeps the note from creating downstream friction.

Banking, the EIN, and getting investor money to land cleanly

Before a note can be funded, the company needs a way to receive money in its own name. That starts with an Employer Identification Number, which the company obtains for free by filing Form SS-4 with the IRS. For a foreign founder without a Social Security number, the EIN is typically issued in roughly 8 to 10 business days when filed by fax or mail. The EIN is the tax identity banks and investors expect to see, and it is the prerequisite for opening a company account that keeps the raise separate from personal funds.

With an EIN in hand, a non-resident founder can open a United States business account through providers that serve foreign-owned companies, such as Mercury, Wise, Relay, Lili, or Payoneer. Having the note proceeds land in a dedicated company account matters for more than tidiness. It establishes a clear record that the funds belong to the entity, supports the bookkeeping an investor will later scrutinize, and reinforces the separation between owner and company that protects limited liability. Investors increasingly ask where their money will sit before they wire it.

Cross-border wires add their own friction. An investor sending funds from abroad may face intermediary bank fees, currency conversion, and compliance checks that delay the deposit. Founders should confirm the exact account details, expected fees, and the entity name as registered before requesting a wire, because a mismatch between the wire instructions and the legal entity name can hold money in limbo. Treating the banking setup as a deliberate step, completed before the note closes, keeps the financing from stalling at the moment it should be simplest.

Tax reporting touchpoints for the foreign founder

A convertible note creates several reporting moments that a non-resident founder needs to track. While the company remains a single-member foreign-owned disregarded entity, the central federal obligation is Form 5472 paired with a pro forma Form 1120, reporting reportable transactions between the company and its foreign owner or related parties. The penalty for failing to file, or filing late, is $25,000. A note round can generate reportable transactions, for example if the foreign owner personally lends to or borrows from the company in connection with the financing, so the raise should be documented carefully enough to support the filing.

Interest is the other recurring touchpoint. Interest accruing on a note held by a foreign lender can raise United States withholding questions, because interest paid to a non-resident may be subject to withholding unless an exemption or treaty rate applies. Whether the portfolio interest exemption or a treaty reduces or eliminates that withholding depends on the lender's residency and the specifics of the note. Founders should flag interest terms to a qualified tax professional rather than assume the low headline rate makes the issue negligible.

The most consequential reporting change arrives at conversion. When the note converts and a second member joins, the company's default classification shifts from disregarded entity to partnership, which means a different federal return and partnership reporting for the year of conversion, potentially including withholding on income allocated to foreign members. A founder who has been filing Form 5472 each year cannot simply continue that pattern after conversion. Anticipating the change keeps the company from filing the wrong forms in the very year its capital structure becomes more complex. This is general information and not a substitute for advice from a tax professional familiar with the founder's situation.

Convertible notes versus SAFEs, and other related terms

The instrument most often compared with a convertible note is the SAFE, covered in its own glossary entry. The defining difference is debt. A convertible note is a loan that accrues interest and carries a maturity date, while a SAFE is not debt at all and has neither interest nor a maturity deadline. That makes a SAFE lighter for the founder in some respects, because there is no looming repayment date to manage, but it also removes the pressure that sometimes pushes a company to close its next round. Many founders weigh the two based on how much structure and deadline pressure they want in the financing.

Both instruments share the same conversion vocabulary. A valuation cap and a discount appear in both, and the post-money versus pre-money distinction that the SAFE entry highlights has a parallel in how note conversions are calculated against the pre-money unit count. Both are securities, and both eventually convert into equity that creates new members in an LLC or new shareholders in a corporation. Understanding one instrument makes the other far easier to read, which is why founders comparing term sheets benefit from learning the shared mechanics rather than memorizing each document separately.

Beyond the SAFE, a founder will encounter related concepts that surround any note round. The Operating Agreement governs how converted interests are issued in an LLC. The priced round, sometimes called a Series A or seed equity round, is the triggering event most notes are written around. The capitalization table, or cap table, tracks who owns what before and after conversion. Knowing how a note connects to these neighboring terms turns an isolated document into a piece of a larger financing picture that the founder can navigate with more confidence.

Edge cases that catch founders off guard

Several edge cases deserve attention because they appear quietly and create outsized problems. The first is the stacked note round, where a founder raises multiple notes over many months at different caps and discounts. Each note converts on its own terms, and at the priced round the company can face a tangle of conversions producing different per-unit prices for different investors. Without careful tracking, the cap table at conversion looks nothing like what the founder expected, and reconciling it under deal pressure is stressful. Modeling the combined effect of all outstanding notes before adding a new one prevents this pileup.

A second edge case is the acquisition before a priced round. Many notes include a change-of-control provision that decides what happens if the company is sold while notes are still outstanding. Some notes convert at the cap, some pay a multiple of principal, and some give the holder a choice. A founder who has not read this clause can discover at a sale that note holders are entitled to terms that materially change the proceeds. The change-of-control language is easy to overlook precisely because it addresses an outcome the founder is not focused on at signing.

A third edge case is the note that never converts because the company plateaus into a modest, profitable business rather than raising another round. In that scenario the note simply matures as debt, and the company owes principal and accrued interest in cash it may not want to part with. For a non-resident founder running a lean LLC, this is a realistic outcome rather than a rare one, and it is exactly the situation the maturity clause governs. Planning for the case where the optimistic round never arrives is as important as planning for the case where it does.

Common misunderstandings to clear up

The most persistent misunderstanding is that a convertible note is equity from day one. It is not. Until conversion, the note is debt, the investor is a creditor rather than an owner, and they hold no membership interest, no vote, and no claim on profits beyond the interest the note accrues. Founders sometimes act as though early note holders are already partners, which can blur governance and create expectations the documents do not support. Treating note holders as lenders until the moment of conversion keeps the relationship aligned with what the paperwork actually says.

A second misunderstanding is that the headline loan amount measures the dilution. As the worked example showed, a low valuation cap on a successful company can hand a note holder far more ownership than the dollar figure implies. Founders who track only the cash raised, and not the implied ownership at various future valuations, can be surprised by how much of the company converts away. The cap and discount, not the principal, drive real dilution, and a founder should model that across a range of outcomes rather than anchoring on the amount wired.

A third misunderstanding is that the simplicity of the document means the obligations are simple too. A note may be short, but it sits on top of securities law, triggers tax classification changes when it converts inside an LLC, and can reshape the company's filings from Form 5472 to a partnership return. The brevity of the paperwork is not a measure of the weight it carries. Reading the full instrument, modeling the conversion, and planning the formation, banking, and tax steps around it is how a non-resident founder keeps a convertible note working as the bridge it was meant to be.
