When you buy or sell a Singapore home, check the outstanding property tax before legal completion and ask how the current year’s bill will be split. IRAS warns buyers that outstanding tax can remain payable after a transfer, even if the previous owner should have paid it. Your conveyancing lawyer or HDB officer can check the balance and help settle it.
The split between seller and buyer is a private arrangement reflected in the conveyancing documents. IRAS does not work out that split or arbitrate it. After completion, verify that the Notice of Transfer has been filed, check the buyer’s first assessment and review the seller’s GIRO separately.
- Check the property tax balance before legal completion.
- Confirm the contract’s apportionment and which amounts were paid.
- Check who files the Notice of Transfer and when.
- Review the first bill, rate and effective dates after transfer.
- Close or update GIRO only after checking the outstanding balance.

Start with the pre-completion checks. If the home has already changed hands, go to the Notice of Transfer and GIRO chapters.
Chapters 1–3
IRAS’s buyer guidance says outstanding property tax can remain payable after the property transfers, including arrears the previous owner should have paid. For a private residential purchase, ask your lawyer about the legal requisition to check the tax position. For an HDB purchase, check the position with the HDB officer or solicitor acting. Obtain the actual balance rather than assuming a recent bill has been paid.
Separate a bill from evidence of payment
A seller may show an annual bill or a schedule of deductions. Ask what has been paid, what remains outstanding and whether there are arrears. Give the records to the conveyancing contact and ask how each amount will be dealt with. A recent GIRO payment could be only one instalment. Check the account rather than assuming it covers the full year.
Record the relevant property and period
Match the address and bill period to the home being transferred. If the seller owns more than one property, check that a receipt or account entry actually refers to this one. Keep the balance date and the completion date visible. Ask for an updated check if the timing changes or a new bill is issued.
Resolve a difference before assuming it will disappear
If the seller’s figures differ from the official result, ask for the documents that explain the difference. It might be a recent payment, a changed assessment or an amount attributed to another period. Ask the lawyer how the difference will be handled at completion. Do not count a promised payment as settled until the appropriate person can verify it.
Tell your conveyancing contact if a bill has just been issued
If a new property tax notice arrives between the initial check and completion, give it to the person handling the transfer. Ask whether the current account balance and apportionment should be updated. Compare the issue date, period and property address with the earlier record. If a payment has recently been made, keep its reference and ask when it is reflected. An up-to-date account helps the parties reconcile a late notice without treating it as proof that either side has already paid.
Ask who is meant to receive notices during the handover
If the parties will move shortly before or after completion, check where tax correspondence will go and who should be notified. Keep the solicitor’s or HDB officer’s contact and the official property reference. If a notice reaches the seller after the transfer, verify its period before forwarding or acting on it. A bill delivered to an old address does not tell you who bears the charge under the settlement.
| When | What to check |
|---|---|
| Before completion | Outstanding tax and apportionment |
| At completion | Settlement entries and who bears each period |
| After transfer | Notice of Transfer and IRAS acknowledgement or bill |
| When closing payment arrangements | Old GIRO, current balance and new owner’s payment setup |

IRAS describes property tax as payable yearly in advance and says sellers are required to pay the full year before selling, with separate guidance to consult the lawyer where payment is by GIRO. The current year’s tax can then be apportioned between the parties under the purchase arrangements. The conveyancing lawyer or HDB officer will usually help with the figures.
Check the period in the settlement statement
If the seller has paid tax for a period the buyer will own the property, the buyer may reimburse the relevant share. Ask which dates and calculation the lawyer used. Check whether the settlement line is a reimbursement, a payment of an outstanding amount or an adjustment. Keep it separate from Buyer’s Stamp Duty and other completion costs.
A simple example of an agreed reimbursement
Assume the completion statement allocates $900 of an already-paid annual bill to the buyer. That $900 is a private settlement amount between the parties on the assumptions used. It does not mean the buyer pays the same $900 to IRAS again. Check the actual account and the lawyer’s statement. If an assessment is later revised, ask how the documents handle any further adjustment.
If the parties disagree about the split
IRAS says it does not apportion or arbitrate property tax liabilities between seller and buyer. Ask the conveyancing contact to explain the relevant agreement and dates. Keep the calculation and any correspondence. If the bill appears incorrect for another reason, such as the tax rate or assessed value, take that issue to IRAS through the appropriate process.
Check what the settlement does with an unpaid amount
Suppose the seller pays by instalments and part of the annual tax remains unpaid at completion. Ask the lawyer whether the statement provides for payment to IRAS, a private adjustment or another settlement arrangement. Confirm which portion relates to the seller and which relates to the buyer under the agreement. Keep proof of any payment actually made. A line that allocates the cost between the parties does not by itself prove the account has been paid.
Compare the relevant periods if the bill changes
If IRAS changes the assessment after completion, check the property, period and effective date. Ask whether the private agreement requires any later adjustment and who will handle it. If the new charge or refund is linked to an occupancy decision, verify the actual rate with IRAS separately. Keep the original calculation and the revised bill so the change is traceable.

IRAS says the conveyancing lawyer usually notifies it of the sale or transfer within one month by filing a Notice of Transfer. Ask who is doing this for the actual transaction. Keep the completion and notification records. If you do not receive the expected acknowledgement or the account still shows the old details, ask the lawyer or HDB officer to check the status.
Check the name and address on the acknowledgement
Verify the property and ownership details and check who is to receive the bills. If the home is jointly owned, make sure the household knows who will monitor the account and pay. Keep the official records accessible so that a notice is not missed during a move. A privately agreed handover date and an IRAS update may occur on different dates.
Check owner-occupier rates separately
If you intend to live in the home, review the rate indicator and the relevant IRAS guidance. Some purchases may have owner-occupier rates applied automatically under specified conditions. Check the actual facts if another home already receives the concession, if there is a tenant or if you will not move in immediately. Use the IRAS process for a status change rather than trying to fix it through the apportionment calculation.
Verify what happens if no first bill appears
Check your official account and ask who received any notice. Confirm the date of transfer and whether the ownership update has been processed. Do not assume that no bill means no tax. Keep the completion instructions and any evidence of payments already made available when asking about the account.

The seller should check the actual balance and settle overdue tax before terminating GIRO, following IRAS guidance. If the GIRO arrangement only covers the sold property, IRAS directs sellers to contact their bank. If it covers other taxes or properties, check IRAS’s instructions so that payments you still need are preserved. Discuss the remainder of the year with the lawyer when the tax is being paid by instalments.
Check the timing of a cancellation
IRAS asks taxpayers who are informing it to allow at least one week before the end of the month to stop the following month’s deduction. Check the current instructions for your arrangement and monitor the next account entry. If a deduction still occurs, ask which property and period it relates to. Do not assume every existing GIRO payment should be stopped immediately on transfer.
A buyer should set up their own payment arrangements
Check the payment deadline and whether you intend to use GIRO for the new property. Confirm the account and effective date using official channels. A seller’s arrangement is not a payment plan for the buyer. Keep receipts or confirmations for any one-off payment during the transition.
Reconcile a deduction that follows completion
If the seller sees another deduction after transfer, check whether the account remained active, the deduction relates to an earlier period or the conveyancing settlement already accounted for it. Give the payment date and transaction details to the relevant party. Keep IRAS’s account treatment separate from any reimbursement agreed between the seller and buyer.
A GIRO arrangement covers two properties
A seller may keep a second property or use one arrangement for other taxes. Before cancelling anything, check the IRAS account and follow the instructions for a multi-property or multi-tax arrangement. Ask which deduction is due next and which part you want to change. Retain the confirmation and check the following month’s transactions. This reduces the risk of stopping a payment that still needs to continue.
A joint buyer sets up the first payment
Agree who will monitor the bill and pay while the household is moving. Check which account and property the payment relates to, and verify any GIRO activation through the official service. If the first bill is due before the new arrangement takes effect, ask what payment is required in the meantime. Keep the payment proof with the acknowledgement and transfer details.

A new HDB flat
IRAS says property tax for newly constructed HDB flats starts from the date the buyer takes possession. Keep the handover record and check the first bill. If you bought resale instead, ask about the current year apportionment with the seller. The source documents and the relevant date can differ between the two transactions.
A new private condo
The assessment for a newly completed private property can begin at the earlier of Temporary Occupation Permit (TOP) or Certificate of Statutory Completion (CSC), even if the buyer receives keys or moves in later. Ask your lawyer or the developer how the contract allocates the tax. Check occupation and the rate separately. The building assessment date and what the buyer must reimburse are distinct questions.
A resale home with a tenant
If you buy a tenanted home, check when the tenancy ends and how the current rate applies. Ask the lawyer about the tax split at completion and ask IRAS what to do if you later move in. Keep the tenancy and occupation dates in the same file, with each event clearly named. A change from seller to buyer does not itself establish that the home is owner-occupied.
A move across the end of the year
If legal completion falls near the end of December, check which annual bill the settlement covers and whether the following year’s bill has been issued. Verify which period the buyer and seller each bear and whether the next assessment uses the same rate. Ask for an explanation of any overlapping figures before assuming they represent a duplicate charge.
A seller pays a bill that overlaps the buyer’s ownership
Consider a seller who has paid the annual bill in full and completes the sale halfway through the year. The conveyancing contact can explain the portion the buyer is expected to reimburse under the purchase terms. Ask what happens if the applicable rate changes after transfer or the bill is later revised. Verify which amounts are final and which may be adjusted. Do not treat the annual amount as a second payment due to IRAS if the account already records it as paid.
A buyer gets a different figure after moving in
Compare the new bill with the completion statement and note whether the difference is due to the rate, Annual Value, tax period or a payment already credited. Ask IRAS about the assessment and the conveyancing contact about the private settlement. If the records cover different periods, make separate entries in the household budget. This helps you identify whether you are looking at a new charge, a reimbursement or simply a different way of presenting the same amounts.

If the seller was eligible for owner-occupier rates but has not applied, IRAS’s seller guidance says to apply at least six weeks before transfer. It says it does not accept such an application after the seller stops being the owner. Check the requirements and do not wait for completion to ask. IRAS also states a five-year limit from excess tax paid for a successful applicant’s refund claim under the described process.
Identify the issue before choosing a route
If the amount is disputed because the rate appears wrong, ask IRAS about the rate and the relevant dates. If the issue is the private split, ask the lawyer. If there is an outstanding payment, verify the current account and how the settlement handled it. A short chronology with the transfer date, bill period and payment makes each question easier to resolve.
Keep a file after the sale or purchase
Retain the settlement statement, annual bill, notices, receipts and any GIRO confirmation. Give each record a date. If a bill is revised, compare it with the earlier one and ask what changed. Keep any refund or apportionment discussion with the specific account and property rather than combining it with other homes or taxes.
Keep a dated handover note for tax as well as keys
Write the legal completion date, any later physical possession date and when the buyer actually began living in the home. Add the tax bill period and what the settlement statement says each party pays. If you bought with a tenant in place, include the tenancy dates too. When asking a question after the move, give the person who can answer it the dates and the relevant papers. This helps separate a missing transfer update, a change in rate and a private reimbursement.
Confirm that the last action really closed the issue
After a payment or revision, check the account for the correct property and period. If the lawyer settled a sum on completion, retain the evidence and compare it with the account record. If an application was submitted for the owner-occupier rate, keep the effective date in the response and compare it with the next bill. If one issue remains open, record who is following up and when you expect a reply.

Who files the Notice of Transfer?
IRAS says the conveyancing lawyer usually files it within one month. Check who is handling the notification for your transaction.
Should the seller cancel GIRO immediately?
Check the remaining balance and whether the arrangement covers other taxes or properties. Follow the bank or IRAS instructions for the actual arrangement.
