This is not the "should you outsource" question; that decision belongs on our page comparing [in-house, software and outsourced payroll](/insights/payroll-in-house-software-or-outsourced-singapore). This is what to check once you have decided to look at providers: who actually files CPF and IR8A, who is accountable when a deadline slips, what happens the week your contact is on leave, and how your data comes back if you leave.

## How do I choose a payroll provider in Singapore?

A good Singapore payroll provider files CPF and IR8A directly under its own Corppass access, not a file handed back for you to submit. Before signing, confirm who is contractually accountable when a deadline slips, what happens when your named contact is away, and exactly how your payroll data and records return to you if you switch providers later.

## Key points

- The biggest split between providers is whether they file CPF and IR8A directly under their own Corppass authorisation, or return a file for someone on your team to upload. Ask this before you ask about price.
- The CPF Submission Number and Corppass access stay registered to your entity regardless of who operates them day to day. Outsourcing the work does not outsource the employer's legal responsibility.
- A named contact going on leave, or leaving the firm, is one of the most ordinary causes of a missed cycle. Ask what cover looks like before you need it, not after a deadline has already passed.
- Accountability for a missed deadline belongs in the service agreement, in writing. CPF Board and IRAS hold the employer liable either way; a provider's internal service standard only decides whether you have recourse against the provider afterward.
- Confirm before signing, not during an exit, what format your payroll history, CPF records and IR8A data come back in if the relationship ends.

A shortlist of three payroll providers can look almost identical from their websites: same software logos, same promise of "full compliance", same generic case study about a growing SME. The differences that actually matter only show up once you ask five specific questions, and most employers only find out the answers the hard way, after a deadline slips or a contact goes quiet. Ask these before you sign, not after: who actually files CPF and IR8A, who is on the hook when a deadline is missed, what happens the week your contact is on leave, and how your data comes back if you ever leave.

This is a narrower question than whether to outsource payroll at all. If that decision is still open, our comparison of [running payroll in-house, on software, or through an outsourced provider](/insights/payroll-in-house-software-or-outsourced-singapore) covers it properly and is not repeated here. This page assumes you have decided to look at providers, and is about telling a genuinely accountable one from a well-marketed one.

## Does the provider file CPF and IR8A directly, or hand you a file to submit?

This is the single question that separates two different services being sold under the same word, "payroll".

One model: the provider holds its own Corppass authorisation and submits CPF contributions and IR8A filings directly to CPF Board and IRAS, on your behalf, under your entity's registration. Your team reviews and approves what goes in each cycle, but does not physically submit it. The other model: the provider calculates the numbers and hands back a file, a report, or a set of figures, and someone in your own organisation performs the actual submission through your CPF Submission Number and your myTax Portal login.

Neither model is wrong, but they carry different risk. In the first, the last person to touch a filing before it reaches the regulator works for the provider. In the second, it is you, which means an error the provider made can still be caught, or missed, by whoever on your team does the upload. Providers rarely volunteer which model they are, because "we handle your payroll" sounds identical either way in a sales conversation. Ask directly, and ask to see the submission step described, not just the payroll calculation.

## How does Corppass third-party authorisation actually work?

Whichever model the provider uses, the mechanics run through Corppass, not around it. CPF Board requires an employer to set up the relevant CPF e-service (the one covering CPF services for employers and business partners) in the Corppass portal and assign authorised users before anyone, staff or provider, can transact on the employer's behalf. That authorisation is granted and can be revoked by your own Corppass administrator, which is worth confirming yourself rather than taking a provider's word for how it works.

Here is a limit worth stating plainly: neither CPF Board's published guidance nor IRAS's makes explicit exactly which Corppass role or permission level a third-party provider needs, or whether the CPF Submission Number itself can sit with a vendor rather than the employer. What is clear is that the underlying registration, the CSN and the entity's Corppass account, stays yours. What is less clear, and worth asking the provider to demonstrate rather than describe, is precisely what access they are requesting and for how long. A provider that can walk you through the exact Corppass role it needs, and is comfortable with you revoking it on notice, is behaving the way a provider that expects to be trusted with statutory filings should behave.

## Who is accountable when a deadline slips?

Start from the fact CPF Board and IRAS will not change for you: the employer is liable, not the provider. CPF contributions are due on the last day of the calendar month, and enforcement action follows if payment is not made by the 14th of the following month (or the next working day if the 14th falls on a weekend or public holiday). Interest runs separately from that enforcement date: 1.5% per month, starting the day after the actual due date, with a minimum charge of S$5. Those are two different dates doing two different jobs, and a provider that only tracks the 14th, treating it as the deadline rather than the enforcement trigger, is already running your compliance on the wrong calendar. Our page on [CPF late payment penalties](/insights/cpf-late-payment-penalty-singapore) sets out the full ladder, interest, composition, and prosecution, if you want the detail behind what "late" actually costs.

The annual filing carries its own exposure. Once an employer has five or more employees, participation in the Auto-Inclusion Scheme is compulsory, with submission due by 1 March; missing it carries a fine of up to S$5,000 under section 94(1) of the Income Tax Act 1947, and directors who ignore IRAS's own notices face personal exposure of up to S$10,000 and up to 12 months' imprisonment. IRAS reported over 900 employers prosecuted for this in Year of Assessment 2023 alone, with penalties exceeding S$1 million in total. None of that liability moves to a provider by virtue of a service agreement.

What a service agreement can do is decide whether you have any recourse afterward. If the contract is silent on what happens when the provider causes a missed deadline, you are relying on goodwill, not a remedy. Ask, plainly, before signing: if a deadline is missed because of an error on your side, what happens; and if it happens because of an error on theirs, what happens. If the second answer is vaguer than the first, that is worth noticing. A provider unwilling to put its own accountability in writing is, in practice, telling you it expects the fallout to land on you regardless of whose mistake it was.

## What happens when your named contact is on leave, or leaves the firm?

Most payroll relationships run through one named person: an account manager, a payroll executive, sometimes literally one freelancer. That works fine every month the person is available, and it is silent about what happens the one month they are not, whether that is annual leave, illness, or resignation from the provider.

This is where structure matters more than the sales pitch. A bureau with a team behind each account should be able to name a backup without hesitation, describe how handover works mid-cycle, and show that more than one person can see your data and your filing history. A single-operator arrangement, however competent day to day, has a bus factor of one, and a provider that cannot answer this question cleanly is showing you the gap before you have signed anything. Our piece on [payroll bureau versus software](/insights/managed-payroll-bureau-vs-software-singapore) goes further into where each model's characteristic failure actually sits, a bureau's tends to be a change nobody told it about in time, which is worth reading alongside this if a bureau is what you are evaluating.

## How does your data come back if you leave?

This is the question employers ask least and regret not asking most, because it only becomes urgent once you are already trying to leave, with a notice period running and a new provider waiting on records that have not arrived yet.

Ask for this in writing before signing, not during an exit: a complete export of payroll history, CPF contribution records, and past IR8A filings, for however many years you are required to keep them, in a format your next provider or your own team can actually use, not a locked PDF or a summary report that omits the underlying data. A provider confident in its own service should have no difficulty committing to this in the contract. One that hedges, or treats the question as unusual, is telling you something about how the eventual handover is likely to go.

## A short framework for the shortlist

Run each provider on your shortlist through the same five questions, in the same order, and write down the answers rather than relying on memory of the sales call:

1. Do they file CPF and IR8A directly under their own Corppass access, or return a file for your team to submit?
2. What Corppass access are they requesting, specifically, and are you comfortable granting and later revoking it?
3. What does the service agreement say about accountability when a deadline is missed, on either side?
4. Who covers your account if your named contact is on leave, or leaves the firm, and can they demonstrate it rather than just assert it?
5. What do you get back, in what format, if you switch providers later, and is that written into the contract now?

A provider that answers all five without hedging has probably run this due-diligence conversation before and expects to. One that can only really talk about its software dashboard, however polished, has not shown you it can run the compliance underneath it.

## Where this fits with the wider decision

If you are still deciding whether outsourcing payroll makes sense at all, that comparison lives on our [in-house, software or outsourced payroll](/insights/payroll-in-house-software-or-outsourced-singapore) page. If you have settled on outsourcing and are weighing a bureau against payroll software you would run yourself, see [payroll bureau vs software](/insights/managed-payroll-bureau-vs-software-singapore). And whichever provider you choose, or whether you stay in-house, the recurring obligations do not change, monthly CPF, annual AIS, event-triggered filings, all mapped out on our [Singapore payroll compliance calendar](/insights/singapore-employer-payroll-compliance-calendar).

We run [payroll processing](/services/payroll) for employers who would rather these five answers were settled once, in a written agreement, than reconstructed after something has already gone wrong. If you are mid-shortlist and want a second opinion on what a provider has told you, that conversation costs nothing to have before you sign anything.

## Frequently asked questions

### Should a payroll provider file CPF and IR8A directly, or is it fine if they hand back a file for us to submit?

Either can work, but the two are different services and should be priced and contracted as such. A provider that files directly needs its own Corppass authorisation and is closer to the process on filing day. A provider that calculates and hands back a file leaves the final submission, and the last chance to catch an error, with your own team. Ask which one you are actually buying before comparing quotes.

### Does using a payroll provider transfer legal responsibility for CPF or IR8A to them?

No. CPF Board and IRAS hold the employer responsible for accurate, on-time contributions and filings regardless of who operates the process. A provider can be contractually liable to you for its own errors, and that clause is worth negotiating, but it does not change who the regulator looks to first.

### How is Corppass access for a payroll provider actually set up?

The employer sets up the relevant CPF e-service in the Corppass portal and assigns authorised users before anyone, whether an internal staff member or a provider, can transact on the employer's behalf. Your own Corppass administrator grants and can revoke that access, which is worth confirming directly rather than taking a provider's description of the process at face value.

### What happens if our payroll provider's staff member handling our account leaves or is on leave?

That depends entirely on how the provider is structured, which is exactly why it belongs on your due-diligence list rather than being assumed. A bureau with a team behind each account should be able to name a backup without hesitation. A single freelance operator, or a provider that visibly cannot answer the question, is telling you where the risk sits before you have signed anything.

### Who pays the CPF late payment interest or AIS penalty if our provider misses a deadline?

CPF Board and IRAS bill the employer, not the provider, because the employer is the party registered with them. Whether you can then recover that cost from the provider depends entirely on what the service agreement says about missed deadlines. If it says nothing, you are relying on goodwill rather than a contractual remedy.

### What should we get back from a payroll provider if we switch to someone else?

At minimum, a complete, usable export of payroll history, CPF contribution records and past IR8A filings for however many years you are required to keep them, in a format your next provider or your own team can actually work with, not a locked PDF. Ask for this in writing before you sign, since it is a poor time to negotiate once notice has already been given.

### Is a cheaper payroll provider a red flag?

Not on price alone, but a quote that is unusually low is worth pressure-testing against the same questions as any other provider: does it include direct filing or only calculation, what cover exists if the named contact is unavailable, and what the service agreement says about a missed deadline. A lower fee that also means a leaner team behind your account is a trade-off, not automatically a saving.
