Every Singapore company that wants to transact with government agencies — file taxes with IRAS, submit CPF for employees, lodge annual returns with ACRA, apply for grants with Enterprise Singapore, or renew work passes with MOM — needs a working CorpPass. It is the single sign-on that authenticates a business (rather than an individual) across the entire Singapore government digital ecosystem, and it is a compulsory step for every newly incorporated private limited company.
Yet CorpPass is one of the most common tripping points we see. New founders assume that having Singpass is enough, or that the company secretary handles it silently. Neither is true. Miss the CorpPass setup and you cannot file your first Estimated Chargeable Income return, cannot pay CPF, cannot even open certain corporate bank accounts. Here is what you need to know.
What is CorpPass?
CorpPass is the trusted digital identity for businesses transacting with the Singapore Government. Managed by GovTech Singapore, it replaced the older EASY, e-Services Authorisation System, and SingPass-for-business logins in 2018. Today, more than 260 government digital services require CorpPass authentication, including IRAS myTax Portal, ACRA BizFile+, CPF EZPay, MOM EPOnline, Enterprise Singapore’s grant portals, and MAS’s various filing systems.
CorpPass is issued at the entity level and mapped to individual Singpass holders who are appointed as Administrators or Users of the entity. This lets a company scale its digital operations: one person cannot bottleneck every filing, and departing staff can be off-boarded cleanly without changing anyone’s personal Singpass.
Who needs a CorpPass?
Every registered Singapore entity that transacts with the government needs CorpPass, including private limited companies (Pte Ltd), public companies, limited liability partnerships (LLPs), sole proprietorships, and foreign entities registered with ACRA. Even a dormant company will eventually need CorpPass to file its annual return, so treat it as part of the standard post-incorporation setup.
Roles: Administrator, Sub-Administrator, User, Enquiry User
CorpPass distinguishes four roles:
- CorpPass Administrator — the master account holder. Every entity must have at least one. The Administrator can grant e-service access to Users and appoint Sub-Administrators. Only the ACRA-registered director, sole proprietor, LLP partner or authorised officer can register as the first Administrator.
- CorpPass Sub-Administrator — a secondary Administrator with the same rights as the primary, useful for large organisations that need multiple people to manage roles.
- CorpPass User — an individual granted access to specific e-services (e.g. IRAS filing only). Users cannot grant rights to others.
- Enquiry User — read-only access to specific services. Common for accountants and tax agents needing to view but not transact.
Corporate services firms and accountants act on your behalf via the Third-Party Authorisation module, which lets your appointed corporate secretary or tax agent transact on your CorpPass without you having to add them as Users of your entity.
Step-by-step: Setting up CorpPass for a new company
Step 1: Confirm director eligibility
The individual registering as the first Administrator must be an ACRA-registered director, company secretary, or authorised representative of the entity. Foreign directors without Singpass can register using their FIN (Foreign Identification Number) if they hold a valid Employment Pass, EntrePass or Dependant Pass, or through the Foreign Persons workflow if they have no local pass.
Step 2: Log into CorpPass with Singpass
Go to corppass.gov.sg and click “Register for CorpPass”. Log in with Singpass (two-factor authentication required). If the individual is a foreign director without Singpass, use the “Foreign ID Login” pathway.
Step 3: Register the entity
Enter the entity’s UEN (Unique Entity Number), which appears on your ACRA business profile. The system automatically pulls the entity’s registered name and directors from ACRA. You may be asked to confirm your directorship or authorisation.
Step 4: Verify by ACRA cross-check
CorpPass performs a live verification against ACRA’s BizFile+ register. If your director details are up to date, this is instant. If ACRA has stale data (common right after incorporation), allow 1 to 2 working days for the register to sync.
Step 5: Set up e-service access
Once the entity is registered, add the e-services your company uses: IRAS Corporate Income Tax, IRAS GST, CPF, MOM EPOnline, ACRA BizFile+, and any grant portals. Assign each service to Users with appropriate access levels.
Step 6: Test the login
Before your first statutory filing, log into each e-service via CorpPass to confirm access. IRAS myTax Portal is a good first test — you should see the entity’s name at the top after login.
Common CorpPass mistakes to avoid
The five errors we see repeatedly are: (1) foreign directors trying to register before their EP is issued — you need the FIN to appear in Singpass first; (2) using a personal Singpass to file for the company instead of via CorpPass — IRAS will reject the filing; (3) failing to add e-services beyond IRAS, meaning payroll or grant applications later hit a wall; (4) not off-boarding staff on departure, leaving ex-employees with live filing access; and (5) forgetting to renew the Administrator role when the appointed director resigns — the entity can be locked out if all Administrators leave.
CorpPass and Third-Party Authorisation for accountants
If you engage a corporate services provider or tax agent, you should authorise them via CorpPass Third-Party Authorisation rather than adding them as internal Users. The workflow is: your Administrator logs into CorpPass, selects “Register Third Party”, enters the agent’s UEN, and grants specific e-services. The agent’s own CorpPass then shows your entity in their client list, and they can transact on your behalf without accessing your other services. This is the standard setup for filing corporate income tax, annual returns, and GST via a licensed tax agent.
What happens without CorpPass?
A new Singapore company without CorpPass cannot file its Estimated Chargeable Income (ECI) with IRAS, pay CPF for staff on time (attracting late-payment interest), lodge its annual return with ACRA, apply for grants, or renew work passes with MOM. Corporate bank onboarding is also affected because many banks now verify CorpPass status as part of KYC. The cost of delay compounds fast — a missed CPF deadline is a MOM enforcement matter; a missed IRAS ECI attracts a composition fee under section 65B of the Income Tax Act.
Ongoing CorpPass housekeeping
Treat CorpPass like any other statutory register — review it annually. At each AGM or year-end review, check: is the Administrator still an active director; are all Users still with the company; are Third-Party authorisations for the correct agent; and are e-service permissions still appropriate for each User’s role.
CorpPass looks like a five-minute setup and mostly is — but the five minutes you skip today can cost weeks of catch-up filings, penalties and remedial work later. Build it into your first-month post-incorporation checklist and revisit it annually. Your future self will thank you.
