Closing a Convertible Note or SAFE Round in Singapore: The Corporate Secretarial and Tax Checklist

Short answer: When a Singapore startup converts a convertible note or SAFE into shares, directors need prior shareholder approval under section 161 of the Companies Act, must deal with pre-emption rights in the constitution, and must file a return of allotment with ACRA. For a private company, the shares exist only once ACRA updates its register of members.

Our earlier articles explain what convertible notes and SAFEs are and how their commercial terms work; start with convertible notes and SAFE agreements for Singapore startups if you need that background. This guide covers the part founders tend to leave until the last minute: the resolutions, filings, registers and tax points that make the round legally effective, from signing through to conversion.

What approvals do I need when I sign a convertible note or SAFE?

A board resolution approving the instrument, and in most cases a shareholders’ resolution under section 161 at the same time. Getting member approval at signing avoids a scramble when conversion is triggered.

Section 161 of the Companies Act 1967 says that despite anything in a company’s constitution, directors must not exercise any power to issue shares without the prior approval of the company in general meeting. Approval can be specific to one issue or general, and can be unconditional or subject to conditions.

Timing matters because a general approval does not last indefinitely. It continues until the conclusion of the next AGM or the end of the period within which that AGM must be held, whichever is earlier, unless revoked or varied sooner. However, directors may still issue shares after the approval lapses if the shares are issued under an offer, agreement or option made while the approval was in force and which the approval authorised. A convertible note or SAFE is exactly that kind of agreement, so a specific approval passed at signing, expressly authorising the issue of conversion shares, gives the cleanest audit trail.

Do I need to change the constitution?

Check three things before signing:

• Share classes. If the instrument converts into preference shares or a new series, the constitution must provide for that class. Amending the constitution needs a special resolution and an ACRA lodgement; your company secretary can prepare the resolution and filing.
• Pre-emption. The model constitution for private companies requires new shares to be offered first to existing members in proportion to their holdings, unless the company in general meeting directs otherwise. Many startups have a bespoke constitution or a shareholders’ agreement with similar rights.
• Directors’ powers to borrow and grant options, and any investor consent rights in an existing shareholders’ agreement.

How do I deal with pre-emption rights on conversion?

Either offer the shares to existing members pro rata, or obtain a direction or waiver from the members disapplying pre-emption for this issue. Most rounds do the second, in the same resolution that gives section 161 approval.

Under the model constitution, the pro rata offer must be made by notice stating the number of shares and a time limit for acceptance; only after it lapses or is declined can the directors dispose of the shares. That is impractical when a note converts automatically at a priced round, so the usual approach is a members’ resolution directing that the conversion shares are issued to the noteholders, combined with signed waivers from any shareholder who has contractual pre-emption rights. Our article on pre-emptive rights in Singapore companies explains the mechanics.

What must be filed with ACRA, and when?

Nothing is filed with ACRA when a note or SAFE is signed, because no shares are issued. On conversion, the company must lodge a return of allotment on Bizfile, and for a private company the shares only exist on the register once that filing is made.

ACRA’s guidance is that a private company’s allotment takes effect on the date of filing, once its electronic register of members (EROM) is updated, and that backdating is generally not allowed. Public companies must file within 14 days of the allotment date. The filing is free and processed immediately. If the section 161 resolution has not already been lodged, Bizfile asks you to upload it during the return of allotment. Our step-by-step guide to filing a return of allotment covers the Bizfile screens.

Registers that are easy to forget

If a conversion makes an investor a registrable controller, the company must update its own register of registrable controllers within seven days of being told of the change and then file with ACRA’s central register within two business days. Share certificates must also be issued under section 130AE of the Companies Act. And keep an eye on the 50-member limit for private companies; our article on hitting 50 shareholders explains the employee carve-out.

Do securities laws apply to a small convertible note round?

Yes. Convertible notes, SAFEs and shares are securities, so an offer of them must either come with a prospectus or fit an exemption under the Securities and Futures Act 2001.

Two exemptions are most relevant to early-stage rounds. Section 272A covers personal offers raising up to S$5 million in any 12-month period, made to people likely to be interested because of a previous contact or connection. Section 272B covers private placements to no more than 50 offerees in any 12-month period. MAS applies aggregation rules so that one offer cannot be split up to stay under the limits. Each exemption carries conditions, including restrictions on advertising, so take legal advice before you pitch widely or use a platform.

How are convertible notes and SAFEs treated for tax?

IRAS characterises a hybrid instrument as debt or equity by looking at the legal rights and obligations it creates, not just its label. The answer affects whether returns are treated as interest or as distributions on equity.

IRAS’s e-Tax Guide on hybrid instruments lists factors that point towards debt, such as a fixed repayment date, a non-contingent obligation to pay a pre-determined return and an investor’s right to enforce payment. Factors pointing towards equity include voting rights, subordination to general creditors, participation in the business and an obligation to bear losses through write-down or conversion into shares. No single factor decides the matter; IRAS weighs the combination. A traditional note with a coupon and a maturity date tends to look like debt. A SAFE, which usually has no interest, no maturity and only a right to future shares, has more equity features. If the characterisation matters to your numbers, consider asking IRAS for an advance ruling.

What are the ESOP basics a founder should know?

Employee share options are taxed in the employee’s hands, generally when the options are exercised, and the company has reporting duties. The company’s own tax deduction depends on where the shares come from.

• IRAS generally taxes ESOP gains when options are exercised, and shares under other employee share ownership plans when they vest. Where the plan restricts sale, the gain is taxed when the restriction ends.
• The taxable gain is the open market value of the shares at that point less the amount the employee paid.
• Employers report the gains on Form IR8A with Appendix 8B.
• Under IRAS’s e-Tax Guide published on 30 September 2025, no tax deduction is allowed where a company issues its own new shares to meet its obligations under an employee equity-based remuneration scheme. From YA 2026, a company may claim a deduction for payments to its holding company (or a special purpose vehicle) for newly issued holding company shares. See our article on the YA 2026 deduction for newly issued shares.

Corporate secretarially, an option pool is just another agreement that may require shares to be issued, so the same section 161 and pre-emption analysis applies when options are granted and exercised.

How do I keep the cap table clean?

Treat ACRA’s EROM as the legal record of who owns shares, and make your spreadsheet agree with it after every allotment.

1. Keep a fully diluted cap table showing issued shares, outstanding notes and SAFEs (with discount, cap and maturity) and the option pool.
2. File every section 161 resolution, pre-emption waiver and directors’ resolution in the minute book in date order.
3. After each conversion, compare the EROM extract from Bizfile against the cap table, share by share.
4. Issue share certificates and update the controllers register in the same week as the allotment.
5. Before the next priced round, ask your company secretary to run a diligence check so investors’ counsel finds nothing to fix.

RCS charges S$350 for existing clients (S$500 for new clients) for an allotment of shares, including the subscription agreement, shareholders’ resolutions and filings, and S$100 (S$200 for new clients) for a directors’ resolution. Startups with several changes a year often add the Annual Corporate Package Add On at S$750 a year to the S$600 Annual Corporate Package.

Frequently asked questions

Do I need shareholder approval to sign a SAFE?

Signing creates an agreement that may require shares to be issued, so you should have section 161 approval in place either at signing or before conversion. Approving it at signing, specifically for the conversion shares, is the more robust approach.

Can I backdate the allotment to the date the note converted?

Generally not. ACRA states that for private companies an allotment only takes effect once the return is filed and the EROM is updated, and backdating is generally not allowed.

Is there an ACRA fee for a return of allotment?

No. ACRA lists the return of allotment as free, with immediate processing.

Does a convertible note count towards the 50-shareholder limit?

A noteholder is not a member until the note converts and the shares are allotted. Once converted, each new member counts towards the 50-member limit for a private company, subject to the employee carve-out.

Is interest on a convertible note deductible for the startup?

It depends on whether IRAS characterises the note as debt or equity, based on its legal terms. Notes with a fixed maturity and an enforceable obligation to pay interest are more likely to be treated as debt.
