Avoid Void Conversions Under Section 161: Convertible Notes in Singapore

A convertible note is a short-term loan that converts into equity at a priced round, usually with a cap, a discount, or both. It suits founders raising a bridge before they can price a full round and investors who want debt-style downside protection. Before signing anything, secure shareholder authority under section 161 of the Companies Act. Skip that step, and your conversion can be void.
TL;DR:
- Use a convertible note when the investor requires interest, a maturity date, or the next financing is more than 18 months away, and consider SAFE or CARE for faster, low-cost options without downside protection.
- Secure shareholder authority under Section 161 of the Companies Act before converting notes into shares to avoid the allotment becoming void and ensure legal compliance.
- Model your cap table at multiple future valuations and understand the impact of caps, discounts, interest, and maturity terms to prevent unintended dilution.
- Avoid multi-tranche notes without proper intercreditor agreements, as conflicting terms can cause disputes over conversion priorities and repayment order.
- Consider alternative funding methods like brokered loans for immediate cash needs if waiting for a priced round is unnecessary or if fundraising coordination risks delaying your raise.

What Is a Convertible Note vs SAFE vs CARE in Singapore?
A convertible note is a debt instrument. It carries interest, a maturity date, and a legal claim against the company if things go wrong. A SAFE (Simple Agreement for Future Equity) and its Singapore-law cousin, CARE (Convertible Agreement Regarding Equity), are not debt at all. They are contractual rights to receive shares later, with no interest and no repayment deadline hanging over the company.
That distinction changes who reaches for which tool. Investors writing smaller checks into very early rounds often accept a SAFE or CARE because it is quick to paper and cheap to negotiate. Investors writing larger checks, or those who want a fallback claim if the startup never raises a priced round, tend to push for a note with real interest and a real maturity date.
Singapore convertible notes typically carry 4% to 8% interest with an 18 to 24 month maturity, while SAFEs and CARE agreements skip both. That gap is not cosmetic. A note with an 8% coupon sitting for 20 months accrues real value that converts into extra shares, while a SAFE holder gets nothing beyond the agreed cap or discount.
Quick numeric example: an investor puts in $200,000 on a note with a $4 million cap and a 20% discount. If the priced round values the company at $6 million per share price, the discount alone would put the investor's conversion price 20% below the round price. The cap sets a ceiling of $4 million regardless of where the round lands, so whichever mechanism produces the lower price for the investor is the one that applies.
Here is the rough shape of the decision:
- Choose a note when the investor wants interest, a maturity backstop, or your last round is more than 18 months away.
- Choose a SAFE or CARE when speed and low legal cost matter more than downside protection, and the investor is comfortable with no maturity date.
- Choose CARE over a US-style SAFE when your investor base is local and you want a document already drafted under Singapore law rather than one written for Delaware.
A CARE agreement drafted under Singapore law reduces friction on governing law and dispute resolution compared to importing a YC SAFE wholesale.
How Do Cap, Discount, Interest, and Maturity Actually Work?
Every convertible note lives or dies on four terms. Get the math wrong and you either give away more equity than you meant to, or you hand your investor a worse deal than they thought they signed up for.
- Valuation cap. This sets the maximum company valuation used to calculate the investor's conversion price, protecting early money from paying a later-round price. If your seed note has a $5 million cap and your Series A prices the company at $10 million, the noteholder converts as if the company were still worth $5 million, doubling their effective share count relative to new investors.
- Discount. This gives the noteholder a percentage off the price new investors pay in the priced round, commonly 15% to 25%. A $300,000 note with a 20% discount converting into a round priced at $1.00 per share buys shares at $0.80, turning that $300,000 into 375,000 shares instead of 300,000.
- Interest. Most Singapore notes carry 4% to 8% annual interest, and that interest almost always accrues rather than gets paid in cash. At conversion, accrued interest adds to the principal amount converting into shares, so a note holder rarely walks away with fewer shares than the headline check size suggests.
- Maturity. The note matures 18 to 24 months in most Singapore deals. At maturity, three things typically happen: the parties extend the term, the company repays the note in cash, or the note converts automatically at the cap (sometimes with a bump, like a 1.2x multiple) if no priced round has occurred.
MFN (most favored nation) clauses and pro rata rights round out the term sheet. An MFN clause lets an earlier investor swap into better terms if you later issue a note with a lower cap or bigger discount, which matters when you raise a multi-tranche bridge over several months at climbing valuations. Pro rata rights let the noteholder invest further in the priced round to maintain their percentage ownership, which affects how much room is left for new investors.
Pro Tip: Model your cap table at three different round valuations before you finalize a cap. Founders who only model the optimistic scenario are routinely blindsided by how much a low cap costs them when the actual round prices higher than expected.
What Singapore Company Law Requires Before You Convert
This is the part most founders get wrong, and it is the one that can unwind an otherwise clean raise. Converting a note into shares is a share allotment under Singapore law, and section 161 of the Companies Act requires directors to hold prior shareholder authority before allotting new shares. Without that authority in place, the allotment can be void, which means the shares you thought you issued may not legally exist.
The fix is straightforward but easy to forget under deal pressure:
- Pass an ordinary resolution granting directors authority to allot shares, ideally at the time you issue the note rather than waiting until conversion.
- Refresh that mandate if it has a time limit or if the number of authorized shares changes before conversion happens.
- Prepare board resolutions approving the note terms and, separately, resolutions approving the eventual allotment on conversion.
- File a Return of Allotment with ACRA within 14 days of the shares being issued, and update your electronic register of members immediately.
- Confirm which Securities and Futures Act exemption you are relying on, since offers of securities in Singapore fall under the SFA and most early-stage note issuances lean on the small offers or accredited investor exemptions.
Pro Tip: Draft the SFA exemption reference directly into your note agreement. Investors' lawyers ask for it during diligence, and having it written in from day one saves a scramble later.
Securing shareholder authority upfront, rather than scrambling for it at conversion, is standard practice among Singapore corporate counsel precisely because waiting until conversion risks a void allotment when a shareholder is unreachable or uncooperative months later.
Do You Owe Tax or Stamp Duty on a Convertible Note?
The allotment itself is the good news. When a note converts, the company issues brand-new shares, and stamp duty in Singapore applies to transfers of existing shares, not to new allotments. Conversion on its own typically triggers no stamp duty exposure.
Interest is where the traps live. Interest paid to non-resident noteholders can attract withholding tax under Section 45, at rates that depend on treaty relief and the specific terms of the note. Most Singapore notes sidestep the issue by accruing interest and converting it into equity alongside principal, which avoids the cash interest payment that would otherwise trigger withholding at the point of payment.
A short practical checklist:
- Confirm the noteholder's tax residency before drafting the interest clause.
- Structure interest to accrue and convert rather than pay out in cash, unless the investor specifically wants cash income.
- Check any applicable double tax treaty for reduced withholding rates before assuming the standard rate applies.
- Keep IRAS documentation on hand if a note ever does pay cash interest to a non-resident.
- Remember that stamp duty risk shifts to the transfer stage, not conversion, so flag it if a shareholder later sells converted shares.
Where Convertible Notes Go Wrong in Practice
Multi-tranche notes cause more disputes than any other structural choice. When you raise a bridge in stages, at $3 million, then $4 million, then $5 million caps, over eight months, each tranche has a different economic claim on the same future round. Without coordination, you get competing claims on conversion priority and repayment order if the company runs into trouble before a priced round happens.
- Fix multi-tranche conflicts with an intercreditor deed. An intercreditor deed or bespoke structuring document sets out ranking and sequencing across tranches, so noteholders and the company both know who gets paid first and how conversion order works if multiple caps are in play.
- Watch caps that are set too low. A founder who sets a $2 million cap to attract early money, then grows fast and prices a Series A at $15 million, can watch that early tranche convert into a disproportionate ownership slice, diluting the founder far more than a discount-only structure would have.
- Read every consent right in the note. Notes often bury investor veto rights over future financings, new debt, or option pool changes inside boilerplate language, and those rights function as governance control even though the investor holds no shares yet.
- Take maturity seriously. If a note reaches maturity with no priced round in sight, the company faces repayment demand, forced conversion, or a renegotiation. Directors who keep operating without addressing an overdue note risk questions about their duties if the company later becomes insolvent.
Pro Tip: Before signing a second or third tranche, run all outstanding notes through one model showing combined dilution at your expected next-round valuation. Founders almost never do this until an investor's lawyer forces the exercise during Series A diligence, and by then the numbers are already locked in.
Which Instrument Should You Actually Choose?
Start with three questions: how far away is your priced round, how large is the check, and does your investor want a debt-style fallback? A bridge expected to close within six to nine months and a lead investor comfortable with contractual rights points toward a SAFE or CARE. A longer runway need, a larger check size, or an investor insisting on interest and a maturity date points toward a note.
A working checklist before you sign anything:
- Model the cap against at least two realistic future round valuations, not just your optimistic case.
- Confirm the qualified financing threshold that triggers automatic conversion, so everyone agrees on what counts as a "priced round."
- Check inter-tranche alignment if this is not your first convertible instrument outstanding.
- Confirm board and shareholder approvals are lined up before money changes hands, not after.
Negotiation usually comes down to trading one lever for another:
- A lower cap in exchange for no discount, or a discount in exchange for a higher cap.
- Interest that accrues and converts, rather than a demand for cash payments along the way.
- MFN protection in exchange for accepting a slightly higher cap than the investor originally wanted.
Your Conversion-Day Checklist
Conversion day runs smoothly when the paperwork was right from the start. Pull together the executed convertible agreement, the board resolution approving the allotment, the shareholder resolution granting section 161 authority, and an updated cap table showing post-conversion ownership before you touch ACRA.
Then work through the operational steps in order:
- File the Return of Allotment with ACRA within the 14-day window.
- Update the company's electronic register of members and register of allotments.
- Issue share certificates to the converting noteholder.
- Notify IRAS if the conversion involved a cash interest payment to a non-resident that triggered withholding.
For the agreement itself, Singapore-adapted CARE and convertible loan templates exist specifically to reference the section 161 mandate and the SFA exemption you are relying on. Practitioner-drafted convertible note and term sheet templates for Singapore companies are also worth reviewing for structure, but always have local counsel confirm the governing law and compliance clauses before using an imported US template as-is.
What This Advisory Sees Founders Get Wrong
Most founders treat the convertible note as a legal document problem and forget it is also a cash flow and coordination problem. The paperwork can be flawless and the round can still stall because nobody checked whether the company had the working capital to survive the 18 to 24 months until conversion, or whether three separate noteholders would agree on ranking when the term sheet was silent on it.
Coordinating multiple lenders or investors under time pressure is where a lot of raises quietly fail. Comparing terms across more than 30 lenders at once, rather than negotiating with one counterparty at a time, tends to produce faster, better-informed decisions, whether the question is a convertible instrument or a straight loan.

Not Every Funding Gap Needs a Convertible Note
A convertible note works well when you have time to wait for a priced round and do not mind the dilution math playing out later. If you need cash now, do not want to touch your cap table, or simply do not have a clean qualified-financing trigger lined up, a brokered loan solves the same runway problem without any conversion mechanics at all.

Kapvoy compares offers across 30+ banks and non-bank lenders simultaneously, rather than sending one application and waiting to hear back. That parallel approach is the real advantage over going it alone with a single bank: average approval runs 1 to 3 days, there is no upfront fee or consultation charge, and Kapvoy only gets paid once your funding is disbursed. For founders weighing a startup loan against a convertible raise, or checking whether a term loan fits better than issuing debt to investors, the fastest next step is to check your eligibility in a few minutes and compare real offers before committing to either path.
Where to Verify the Legal and Tax Details
Confirm allotment mechanics directly on ACRA's guidance on share allotment, and check IRAS stamp duty rules for shares before assuming a conversion is stamp-duty-free in your specific case. For securities exemptions, MAS's regulatory overview covers which offers require prospectus registration. For drafting, Singapore-adapted CARE and convertible loan templates and Cooley GO's Singapore convertible note template are useful starting points, always subject to local counsel review.
