If you run a business in Singapore, you’ll hear Corppass a lot. It’s the corporate authorisation system that lets your team use government e-services on your company’s behalf.

In this guide, we’ll cover what Corppass is, who needs it, the key user roles, and how to set up an account. And if your business also deals in multiple currencies, we’ll show you how a Wise Business account can help you simplify international payments and lower your fees when handling them.

What is Corppass?

Corppass is Singapore’s authorisation system for business-to-government (and some partner) digital services¹. In plain English: your team members and service providers sign in with Singpass, and Corppass decides what each person is allowed to do for your entity. It’s operated by GovTech and built for secure, auditable access control.

Since 11 April 2021, the login journey for government e-services starts with Singpass (not a separate Corppass username/password)². Corppass remains the permissions layer sitting behind the scenes. Foreign users who don’t have a Singapore NRIC/FIN can use a Singpass Foreign user Account (SFA) to access selected services (including corporate tax on myTax Portal), then act under Corppass authorisations for the entity.

Corppass supports both Singapore-registered entities and foreign-registered entities that need to transact with agencies, centralising access to digital services across government portals.

Who needs a Corpass account?

Local and foreign identities³

Unique Entity Number (UEN) registered entities (Singapore-registered): If your entity transacts with the government, set up Corppass to authorise staff/agents. Users then log in with Singpass to access the e-services. If you need a refresher on UENs, read our guide to the company registration number (UEN) in Singapore.
Foreign entities without a Singapore UEN (but dealing with IRAS): You can register via IRAS’ foreign-entity Corppass process once you have an IRAS tax reference number.
Entities without a UEN: Don’t assume you’re out. Some non-UEN structures (e.g., REITs, trust funds, VCC sub-funds) can onboard (typically for IRAS services) using agency-specific guidance. Check the services you need first.
Individuals (e.g., self-employed in personal capacity): File with Singpass, not Corppass. Corppass is for entity authorisations.

A GST note (sole proprietors, groups, divisions): For IRAS GST e-services, you’ll use the GST Registration Number (GSTN, “M…”) as the Entity ID and appoint your GST Corppass Admin via IRAS.

This “GST Corppass” is distinct from any Corppass you use under your UEN⁴.

Corppass roles explained (RO, Admin, Sub-Admin, User/Enquiry User)⁵

Registered Officer (RO)

The Registered Officer is your ACRA-recorded key appointment holder (e.g., director, owner, partner).

Their job in Corppass is to approve and manage Administrators. The RO must have Singpass to approve Admins, but they don’t need a Corppass user account unless they also want to transact. An RO may choose to take on the Admin role as well.

Administrator (Admin)

The Admin runs your entity’s Corppass day to day, creating/terminating users and assigning the exact e-services people can access.

For Singapore-registered (UEN) entities, Admins must be NRIC/FIN holders.

Each entity, UEN or foreign, can appoint up to two Admins, and you should always keep at least one active; if both Admins lapse for over 30 days, the entity can be suspended until a new Admin is appointed.

Sub-Administrator (Sub-Admin)

A Sub-Admin helps the Admin manage accounts and permissions, but with a more limited scope defined by the Admin.

It’s helpful in delegating routine access admin to HR/Finance/IT without granting full control.

Here’s the best practice: appoint two Admins for continuity, and keep at least one Sub-Admin to handle day-to-day user management. This reduces lock-outs and avoids suspension if someone leaves suddenly.

The maximum number of Sub-Admin accounts for UEN and foreign entities is 25.

User

A User is any staff member (or appointed service provider) who needs to transact on the entity’s behalf. They can only access the specific e-services the Admin assigns to them (e.g., IRAS myTax, CPF employer services, MOM work pass portals).

There is no limit to the number of User accounts UEN entities can create. On the other hand, foreign entities can only create a maximum of 30 Corppass accounts spanning across all roles.

Enquiry User

An Enquiry User has view-only access — handy for auditors, external secretaries, or directors who need oversight without edit rights.

There is no limit to the number of Enquiry User accounts UEN entities can create. But again, foreign entities can only create a maximum of 30 Corppass accounts spanning across all roles.

How to set up your Corppass account (step-by-step)

What you’ll need first

For Singapore-registered entities (UEN holders)⁶: Your UEN, plus the Registered Officer (RO) and chosen Admin’s details (name, NRIC/FIN, email). You’ll authorise users in Corppass, and everyone signs in with Singpass.
For foreign-registered entities (no Singapore UEN)⁷: Basic business registration documents from your home country and your appointed Admin’s ID details. You can register the Admin either via Singpass (if eligible) or via Foreign ID, and foreign users without NRIC/FIN can log in using a Singpass Foreign user Account (SFA). If you’re setting up from overseas, you might find our guide to starting a business in Singapore for foreigners helpful.

Two key steps (post-2021 login flow)

Step 1: Appoint your Admin and get RO approval. Note that from 11 April 2021, the business login journey starts with Singpass (or SFA for eligible foreign users). Your RO approves the first Corppass Admin online; each entity can have up to two Admins, and you must always keep at least one active.
Step 2: Create users and assign e-services. Once the Admin is approved, they sign in and set up Sub-Admins, Users, or Enquiry Users, then assign the exact government digital services each person needs (e.g., IRAS myTax Portal, CPF EZPay, MOM work pass e-services). New users receive an activation email with a Reference ID; they activate their account using that Reference ID and the entity’s registration number, and thereafter log in with Singpass to transact.

Government services you’ll access with Corppass (ACRA, IRAS, MOM, CPF)

Once your Admin assigns the right e-services in Corppass, your users log in with Singpass (foreign users use SFA) and transact on these core portals⁸:

Accounting and Corporate Regulatory Authority or ACRA (Bizfile): Register a company, update particulars, and file routine submissions. If you’re new to ACRA, check out our quick explainer here
Inland Revenue Authority of Singapore or IRAS (myTax Portal): File corporate income tax, GST, and manage notices/payments. Employees and third parties (e.g., tax agents) must first be authorised via Corppass before they can access your entity’s myTax account. Foreign entities can onboard via IRAS’s Foreign Entity guide.
Ministry of Manpower or MOM (work pass & employer e-services): For managing work pass applications and other employment-related matters. Set up access (e.g., EP eService, Work Permit Online) in Corppass so HR can submit or manage applications. MOM’s guidance explicitly points admins to assign the relevant e-services in Corppass first.
Central Provident Fund or CPF Board (employer contributions): For all employee CPF contribution matters. Before your payroll team can submit contributions in CPF EZPay, your Corppass Admin or Sub-Admin must add your CPF Submission Number (CSN) to the CPF EZPay e-service in Corppass and assign it to the relevant users. CPF provides a step-by-step setup guide for assigning these e-services⁹.
More agency services (and third-party access): You can browse the official Digital Service List to see other agency e-services available via Corppass, and you can authorise third-party providers (e.g., your accounting/tax firm) to act on your behalf for selected services.

Conclusion

Setting up Corppass is a foundational step for running a compliant, low-friction business in Singapore.

Once your roles and permissions are in place, your team can handle ACRA filings, IRAS submissions, MOM work passes, and CPF contributions with the right access — securely, and without permission sprawl. The result: tighter controls, cleaner audit trails, and more time to focus on growth.

💡As you lock down your business foundations, it’s also worth considering how you can streamline your money operations too, especially if you pay overseas suppliers or get paid in multiple currencies from global clients.
