Young couples in Singapore often find themselves at a crossroads: you want to live together, property prices are rising, and waiting until marriage feels like leaving money on the table. The good news is that Singapore private property has no marriage requirement: you can buy a condo with a partner, friend, or sibling without being married. The important work is understanding how ownership structure today affects your ABSD options tomorrow.

The Basics: Private Property Has No Marriage Requirement

Unlike HDB flats which require a family nucleus (married couple, parent and child, siblings) or a single SC aged 35 and above, Singapore private residential property can be purchased by any combination of eligible buyers regardless of their relationship status.

Two unmarried SC individuals can:

• Purchase a private condo together under joint tenancy or tenancy in common
• Each use their own CPF OA for the purchase (up to their individual CPF Valuation Limit)
• Each take a share of the mortgage, assessed on their combined income
• Each benefit from first time buyer 0% ABSD on their respective interest in the property

ABSD Assessment for Unmarried Co-Purchasers

ABSD is assessed on each purchaser's profile individually, based on their residential status and existing property count at the time of purchase. For a joint purchase, each owner is assessed on their proportionate share but in practice, IRAS applies the higher profile rate to the entire purchase if any owner attracts ABSD.

Ownership Structures: Which to Choose

The 99/1 Structure for Unmarried Couples

A tenancy in common with 99% to one partner and 1% to the other is sometimes used to give both partners nominal ownership while minimising the ABSD exposure of the 1% owner for future purchases. Note: IRAS has scrutinised 99/1 arrangements where the 1% owner later buys another property if IRAS determines the 99/1 was structured to artificially preserve first timer status, they may re assess ABSD. Seek legal and tax advice before using this structure as an ABSD planning tool.

What Changes After Marriage

Marriage itself does not trigger ABSD, stamp duty, or any automatic change to your property title. Your ownership structure the day before marriage is identical to the day after. What changes is the ABSD remission available to you and how your combined property count affects future purchases.

ABSD Remission for Married SC Couples

If a married SC couple buys a second property (incurring 20% ABSD) and then sells their first property within 6 months of purchasing the second, they can apply to IRAS for an ABSD refund. This remission is only available to married couples; it was not available if the purchase was made while unmarried, even if you subsequently married.

CPF Usage for Unmarried Co-Purchasers

Each co-purchaser can use their own CPF OA for the purchase. CPF usage is governed by the individual CPF member's account, not the relationship status of the buyers. The CPF withdrawal limit is based on the Valuation Limit (lower of purchase price or valuation), pro rated by ownership share for tenancy in common, or at the full limit for joint tenancy (each member can use CPF up to the full Valuation Limit).

CPF accrued interest: each CPF member's CPF principal plus accrued interest at 2.5% per annum must be refunded to their own CPF OA when the property is sold, regardless of relationship status or whether they are still together.

Practical Checklist for Unmarried Couples Buying Property

• Confirm both partners' ABSD status: Check existing property ownership for each individually. One existing property triggers 20% ABSD on a joint purchase.
• Decide on ownership structure before signing OTP: Joint tenancy vs tenancy in common (and what split) affects both ABSD and succession. Changes after purchase require a separate legal transfer and stamp duty.
• Consider a co-ownership agreement: An unmarried couple should document: what happens to the property if you break up, how mortgage is split, who manages rental income, and exit mechanisms. This is a private agreement: HDB or URA do not require it for private property, but it protects both parties.
• Mortgage assessment: Banks assess the loan on both borrowers' income (Total Debt Servicing Ratio, TDSR at 55% of gross income). Both will be co-borrowers on the mortgage, which affects each person's future borrowing capacity.
• CPF nomination: If one partner dies, their CPF (used for the mortgage) goes to their CPF nominees which may not be you if you are unmarried. Make a CPF nomination if you want your partner to receive your CPF balance.

Frequently asked questions

Can an unmarried couple buy a condo together in Singapore?

Yes. Singapore private property has no requirement that buyers be married. An unmarried couple can purchase a private condo jointly (joint tenancy or tenancy in common) without any marriage prerequisite. Each buyer's ABSD status is assessed individually based on their property ownership count. If both are first time buyers (SC), neither pays ABSD.

What happens to our property ownership ABSD status when we get married?

Marriage itself does not trigger any ABSD. If you both already own property jointly, after marriage you are both treated as having one property in joint names. When you want to buy your next property, both of you will be assessed as having an existing property, meaning 20% ABSD on the second purchase (SC). Planning ahead: if you anticipate buying a second property post marriage, consider whether one partner should buy in sole name initially so the other retains first timer status.
