GIRO is Singapore’s interbank direct debit and credit system that lets banks, government agencies and billers automatically deduct or credit money from a customer’s bank account on a recurring or one-off basis, once the customer has authorised a GIRO arrangement.

Key Takeaways
- GIRO is used for recurring payments such as utility bills, insurance premiums, loan instalments, CPF contributions, income tax and telco bills across Singapore’s local banks.
- Setting up GIRO requires signing a mandate, either on paper or digitally, authorising a specific biller to deduct funds from a nominated bank account.
- Unlike PayNow or FAST, GIRO transactions are batch-processed rather than instant, so payments typically take one to a few business days to reflect.
- Interbank GIRO (IBG) is the mechanism that allows one-off or recurring GIRO payments to move between accounts at different banks, not just within the same bank.
- GIRO arrangements can be cancelled by the customer directly with their bank or the biller, and unauthorised or incorrect deductions can usually be disputed through the bank.
What Is GIRO?
GIRO has long been the backbone of recurring bill payments in Singapore, used by government agencies such as IRAS, CPF Board and town councils, as well as private billers like insurers, telcos and utility providers. Rather than a customer manually paying each bill every month, a GIRO mandate authorises the biller to request payment directly from the customer’s designated bank account on a set schedule.
The system is administered through the local banking network, with Interbank GIRO (IBG) specifically enabling GIRO payments to be processed between different banks, rather than only within a single institution. This is what allows a customer with a DBS account, for instance, to pay a biller whose designated collecting bank is OCBC or UOB.
How Does GIRO Work in Singapore?
Setting up GIRO typically starts with a mandate form, either a physical form with a signature or, increasingly, a digital authorisation through internet banking or a biller’s online portal. Once the mandate is processed, usually within a few business days to a few weeks depending on the biller, recurring deductions begin automatically according to the agreed schedule, commonly monthly for bills and premiums.
| Feature | GIRO | PayNow |
|---|---|---|
| Speed | Batch-processed, 1–3 business days | Real-time, typically seconds |
| Setup | Requires signed mandate with biller | Link mobile number/NRIC to bank account |
| Typical use | Recurring bills, premiums, taxes, loans | Ad hoc person-to-person and person-to-business payments |
| Who initiates | Biller, based on mandate | Payer, per transaction |

GIRO Example
A homeowner sets up GIRO with their town council to pay monthly service and conservancy charges of S$80. After signing the GIRO mandate, either on paper at a service centre or digitally through internet banking, the town council automatically deducts S$80 from the homeowner’s nominated bank account each month, without the homeowner needing to log in and pay manually. If the homeowner later switches banks, they typically need to set up a new GIRO mandate with the updated account details, since GIRO arrangements are tied to a specific bank account.
Advantages of Using GIRO
- Avoids late payments. Automatic deduction removes the risk of forgetting a recurring bill, which can help avoid late fees or service disruptions.
- Works across banks. Interbank GIRO means the payer and the collecting biller do not need to use the same bank.
- Widely accepted for government and utility payments. IRAS, CPF Board, town councils and most utility providers support GIRO, often as their default or preferred payment method.
- Simple to set up once. A single mandate covers ongoing payments, rather than needing manual action every billing cycle.
Risks and Limitations
- Less control over timing. Deductions happen automatically on the biller’s schedule, which requires ensuring sufficient funds are available on the deduction date.
- Slower to set up than PayNow. A new GIRO mandate can take days to weeks to activate, unlike PayNow’s near-instant registration.
- Not designed for one-off, ad hoc payments. GIRO is built around recurring arrangements; for a single payment to a friend or vendor, PayNow or FAST is generally more practical.
- Disputing incorrect deductions takes time. Reversing an erroneous GIRO deduction usually requires raising a dispute with the bank or biller rather than an instant self-service reversal.
GIRO vs Interbank GIRO vs PayNow
| Aspect | GIRO (Intrabank) | Interbank GIRO (IBG) | PayNow |
|---|---|---|---|
| Banks involved | Same bank only | Different banks | Any participating bank |
| Speed | Batch | Batch | Real-time |
| Typical use case | Recurring bills | Recurring bills across banks | Instant transfers, ad hoc payments |
The Bottom Line
GIRO remains the default rail for recurring payments in Singapore precisely because it is simple to set up once and forget, even though it lacks the instant speed of PayNow. Understanding that GIRO is mandate-based and batch-processed, rather than real-time, helps set the right expectations for how quickly a new arrangement will take effect.
Frequently Asked Questions
What does GIRO stand for and what is it used for?
GIRO is Singapore’s interbank direct debit and credit system, commonly used for recurring payments such as utility bills, insurance premiums, loan instalments, CPF contributions and income tax.
How is GIRO different from PayNow?
GIRO is mandate-based and batch-processed, typically taking one to a few business days and used for recurring payments, while PayNow is real-time and typically used for instant, ad hoc transfers.
How long does it take to set up a GIRO arrangement?
Processing times vary by biller, but a new GIRO mandate commonly takes a few business days to a few weeks to become active, depending on whether it is submitted digitally or on paper.
What is Interbank GIRO (IBG)?
Interbank GIRO is the mechanism that allows GIRO payments to move between accounts held at different banks, rather than only within a single bank.
Can I cancel a GIRO arrangement?
Yes, GIRO mandates can generally be cancelled by contacting the bank or the biller directly, after which future automatic deductions under that mandate will stop.
