Payment Services Act Singapore: Does Your App or Platform Need a License?

If you are building a payments app, digital wallet, remittance tool, merchant payment platform, or anything involving moving or storing value in Singapore, one of the first questions you will face is whether you need a licence under the Payment Services Act 2019 (PSA). The Monetary Authority of Singapore (MAS) regulates a wide range of payment activities, and operating without the right authorisation can lead to criminal enforcement action like fines, imprisonment, and forced shutdown.

This article breaks down which activities trigger licensing, which licence class fits your business, the exact thresholds separating a Standard Payment Institution from a Major Payment Institution, and what the MAS licensing process actually looks like end to end.

The Payment Services Act at a Glance

The PSA brought a unified, risk-based licensing regime for payment services in Singapore. Before it, different activities were governed by separate laws like the Payment Systems (Oversight) Act ,2007 and the Money-changing and Remittance Businesses Act, 1996 among them. The PSA consolidated everything into one framework and has been progressively strengthened, with significant amendments taking effect on 4 April 2024.

The core prohibition is in Section 5: a person may not carry on a business of providing any regulated payment service in Singapore unless licensed or exempt. Importantly, the legislation can treat the provision of a payment service as a separate regulated business even where it is embedded within a company's main product. That in-app wallet your e-commerce platform offers? It counts.

The Payment Services Act, 2019 (PSA) administered by the MAS, brought a unified, risk-based licensing regime for payment services in Singapore. Before the PSA, different payment activities were regulated under separate laws (like the Payment Systems (Oversight) Act, 2007 and the Money-changing and Remittance Businesses Act, 1996). The PSA consolidated everything into a single framework.

Section 5 of the PSA generally prohibits a person from carrying on a business of providing a regulated payment service in Singapore unless they hold an appropriate licence or are exempt. Importantly, the provision of a payment service can be treated as a separate business even when it is connected with your company’s main business. So if your app facilitates payments as part of a marketplace or a SaaS platform, you may still need a licence.

Which Activities Trigger Licensing?

If your business provides any of the following “in or from Singapore,” licensing is required:

• Account issuance service: Issuing payment accounts (e-wallets, stored value cards, non-bank credit cards) or any service required to operate them.
• Domestic money transfer service: Local fund transfers within Singapore, including payment gateways and kiosk services.
• Cross-border money transfer service: Inbound or outbound remittances, including facilitating transfers between entities in different countries even if no money is accepted in Singapore.
• Merchant acquisition service: Processing payment transactions for merchants, including providing POS terminals or online payment gateways.
• E-money issuance service: Issuing e-money that users can spend at merchants or transfer to other individuals.
• Digital payment token (DPT) service: Buying or selling digital payment tokens, operating exchange platforms, custodian wallet services, or actively facilitating DPT trades without holding the assets.
• Money-changing service: Buying or selling foreign currency notes.

Three Types of Licences

Based on the risks associated with the scope of payment services a person offers, unless exempt, the person must hold a licence under one of the three licence classes listed in Section 6 the PS Act. These are:

1. Money-Changing Licence (MCL)

For businesses that only exchange physical foreign currency notes and do nothing else. If your app includes any other regulated payment activity, you need an SPI or MPI licence. Most founders can move past this class quickly.

2. Standard Payment Institution (SPI) Licence

Designed for startups and growth-stage businesses operating below specified volume thresholds. An SPI may provide one or more of the seven regulated services but is subject to hard monthly transaction caps (more on these below). Minimum base capital: S$100,000.

3. Major Payment Institution (MPI) Licence

The full-scale licence for businesses that exceed SPI thresholds or those that want to operate without volume restrictions from day one. MPIs can conduct multiple regulated activities at unrestricted scale. Minimum base capital: S$250,000 for most services, rising to S$500,000 for DPT services or cross-border money transfer.

The SPI vs MPI Thresholds

Section 6(5) of the PSA sets the following thresholds. If you exceed any of these, you must hold MPI license.

Do You Actually Need a Licence? Checking the Exemptions

Before applying, you need to confirm your activities are regulated in the first place. Several exemptions exist:

• Banks licensed under the Banking Act do not need a separate PSA licence, though they must notify MAS before offering DPT services.
• Certain low-value or closed-loop systems may fall under the exemptions listed in Part 2, First Schedule of the PSA.
• Transitional provisions under the Payment Services (Amendment) Act 2021 (Saving and Transitional Provisions) Regulations 2024 gave some entities a grace period to apply.

The MAS Licensing Process

Since the revised Guidelines (PS-G01) took effect on 26 August 2024, the process has become more structured. Here is how it works in plain English:

1. Map Your Services

List every activity your platform performs that could constitute a regulated payment service. Cross-reference each against the PSA's seven categories. Many apps trigger multiple service types, for example, an e-wallet with a top-up feature and a peer-to-peer transfer function may simultaneously involve account issuance, e-money issuance, and domestic money transfer services.

2. Commission a Legal Opinion

Engage a Singapore-qualified law firm to produce a legal opinion confirming which regulated services you provide, whether any exemptions apply, and which licence class is appropriate. MAS retains the right to request a second opinion if the first lacks clarity.

3. Build Your Compliance Framework

MAS assesses operational readiness, not just paperwork. Before submission, you must have your AML/CFT programme documented and functional, a compliance officer identified and appointed (or at minimum identified), KYC procedures evidenced in practice, and a transaction monitoring system in place. Frameworks that are documented on paper but not operationally live are one of the most common reasons for rejection or extended processing.

4. Satisfy Capital and Safeguarding Requirements

Confirm your base capital position (S$100,000 for SPI, S$250,000 for MPI). MPI holders must also lodge a security deposit with MAS: S$100,000 if projected monthly transaction value is below S$6 million, or S$200,000 if at or above that level. MPIs conducting e-money issuance must additionally safeguard customer float under MAS Notice PSN07, typically via a trust account at a Singapore bank.

5. Submit the Application

Applications are submitted through GoBusiness, Singapore's centralised business licensing portal. The core document is Form 1 (Application for a Payment Service Provider Licence), accompanied by Form 3 for approval of key appointment holders (CEO, directors), the legal opinion, a detailed business plan, financial projections, and your AML/CFT documentation. For DPT service applicants, an Independent External Auditor (EA) Assessment is also required, covering AML/CFT compliance and consumer protection obligations.

6. MAS Review and Decision

MAS assesses your application against the "fit and proper" criteria: your track record, financial soundness, governance structure, operational readiness, and whether granting the licence would serve the public interest. If material gaps are identified, MAS may place your application on hold for up to six months under the case-on-hold process introduced in August 2024. If gaps cannot be resolved, the application is rejected.

7. Licence Issuance

Once approved, the annual licence fee is paid and MAS issues your e-licence by email.

Conclusion

The Payment Services Act is a mandatory framework that touches almost every consumer and business payment flow in Singapore. For app and platform founders the essential tasks are to identify which of the seven regulated services your product actually performs, estimate scale honestly against the SPI thresholds, and choose the correct licence class from day one.

The SPI licence exists precisely to give smaller players a gentler on-ramp, but it has hard legal boundaries. Plan your growth, anticipate when you might cross the S$3 million or S$5 million thresholds, and start your application early. With a clear business case, solid compliance foundations, and a realistic timeline, getting your MAS licence is very achievable and it is the foundation for building trust with users, banking partners, and institutional counterparties in one of the world's most respected financial hubs
