ABSD in Singapore: Rates, Refunds and How Buyers Plan Around It

ABSD is the largest single number in most second-property calculations, and the tax with the least room for error: it falls due 14 days after you exercise a purchase, computed on the full price, before any of your other plans unfold. Buyers who learn the rules after signing pay six figures for the lesson, and IRAS does not accept ignorance as grounds for a refund. The rates, the one meaningful refund, and the structures buyers use around it, in that order.

The rates since April 2023

Buyer profile	1st property	2nd property	3rd and beyond
Singapore Citizen	0%	20%	30%
Permanent Resident	5%	30%	35%
Foreigner	60%	60%	60%
Entities and trusts	65%	65%	65%

Rates per IRAS, unchanged since the April 2023 revision. Three computation rules do most of the damage in practice:

• ABSD applies to the higher of price or market value, so a below-valuation "deal" saves you nothing on the tax.
• Joint purchases take the worst profile. A citizen buying with a foreigner pays the foreigner's rate on the entire property, not half. Nationals of a handful of countries, including the US, are treated as citizens under free trade agreements; verify against IRAS's remission list rather than assuming.
• The count includes what you already hold. An inherited share of a property, an overseas-exempt assumption that turns out wrong, or a gifted interest all move you up the schedule. Count before you offer.

Payment is due within 14 days of exercising, in cash or CPF for most HDB and citizen purchases (private purchases pay cash first and claim CPF reimbursement). The financing mechanics sit alongside the rest of the CPF rules in our guide to using CPF for property.

The duty underneath: BSD applies to everyone

ABSD stacks on top of ordinary Buyer's Stamp Duty, which every purchase pays regardless of profile or property count. BSD is tiered by price, with the top residential tier reaching 6% on the portion of the price above $3 million; the full schedule is on IRAS's BSD page. On a mid-seven-figure purchase the two duties together can approach the size of the downpayment, which is why any second-property budget starts with the tax line, not the price.

Timing follows the same 14-day rule as ABSD, and both are assessed at the date you exercise the purchase. That date also fixes your property count: a buyer who completes the sale of an existing home before exercising the next purchase is a first-timer again in IRAS's eyes, which is the logic of the sell-first sequence.

The spousal refund: the one real escape hatch

A married couple with at least one Singapore Citizen spouse, buying a second residential property together, can apply for a full ABSD refund if they sell the first property within 6 months of the new purchase, or within 6 months of its TOP for an uncompleted unit.

The conditions are strict and the sequence unforgiving: the couple must front the full ABSD first, both must be parties to the new purchase, and a first home that fails to sell inside the window kills the refund, and IRAS grants no extensions. For upgraders, this refund is the whole financial case for the buy-first sequence, and its risks are the reason most upgraders sell first instead; we weigh the two in should you sell your HDB before buying a condo.

A worked example: the upgrading couple

A citizen couple owns an HDB flat and exercises the purchase of a $1.6 million condo before selling it. The sequence of their money:

1. Day of exercise: they are second-property owners. ABSD of 20%, $320,000, plus tiered BSD, falls due within 14 days, in cash or CPF.
2. The next 6 months: the refund clock runs. They must complete the sale of the flat inside the window, so the flat needs to be priced to transact inside it.
3. After the flat sells: they apply to IRAS for the full $320,000 refund. BSD is not refunded; it was always payable.

The same couple selling the flat before exercising would have paid no ABSD at all, at the cost of arranging interim housing. That $320,000 of working capital, parked for half a year against a deadline, is the real price of skipping the double move.

Structures buyers use, and what each actually costs

• One name from the start. A couple who can qualify for the loan on a single income buys the first home under one spouse. The other remains a first-timer, able to buy a second property later at 0%. The cost is borrowing power: one income services the first mortgage, and the 55% TDSR binds earlier.
• Decoupling. One spouse buys out the other's share of an existing joint property, freeing the exiting spouse to purchase again at first-timer rates. The buyout itself is a part-purchase: it attracts BSD (and ABSD if the buying spouse holds other property), plus legal fees, and CPF used by the exiting spouse must be refunded with accrued interest. Decoupling pays off when the future ABSD saved exceeds today's transfer costs, which takes an actual calculation on your numbers. HDB flats broadly cannot be decoupled between spouses; the route is a private-property one.
• Buying under a trust for a child. Residential property held on trust attracts the 65% entity rate upfront, with a refund path to the beneficiary's rate only under strict conditions. This corner of the regime changes often enough that current IRAS guidance should be read before any planning conversation.
• Simply not holding two. Selling before buying keeps every purchase at first-timer rates and remains, unglamorously, the cheapest structure available to most households.

What does not work: nominee arrangements and undeclared beneficial ownership. IRAS looks through the paperwork to the substance of ownership, and the penalties for avoidance sit far above the tax avoided.

Where ABSD bites hardest in practice

Three situations produce most of the expensive surprises we see:

1. The upgrader who exercises before selling. The 20% hits at exercise, not at completion. A $1.6 million condo demands $320,000 within 14 days, months before any refund application can even begin.
2. The couple with a small inherited stake. A one-eighth share of a parent's flat counts as a property; the "second" home is taxed as one. Check every name on every title before offering.
3. The investor who assumes rates will soften. ABSD rates have risen at every revision since 2011. Budget on today's rates.

Know your profile, your property count and your sequence before you commit to anything. If you want your own structure checked against the current rules, that is a conversation we have every week.
