New launch discount stamp duty: cash rebate or freebie?

A cash discount stated in the document to be stamped can lower the price on which stamp duty is charged; a furniture voucher or a rental guarantee cannot. For a new launch discount, stamp duty turns on four tests taken from IRAS’s wording: is the benefit cash, is it stated in the document to be stamped, is it given on execution, and does the net price still reflect market value.

The Inland Revenue Authority of Singapore (IRAS) works out buyer’s stamp duty (BSD) and additional buyer’s stamp duty (ABSD) on the higher of the price in the document and the property’s market value. On an illustrative S$2,000,000 price, a S$40,000 benefit that passes all four tests lowers BSD by S$2,000 and, for a citizen buying a second home, ABSD by S$8,000. The same S$40,000 as a furniture voucher lowers neither.

This is general information from IRAS’s published guidance, not tax or legal advice, and no named project is said to offer any benefit below. Terms such as BSD, ABSD and option to purchase are in our new-launch glossary; the duty tiers are in our stamp duty guide.

Which developer benefits lower the price stamp duty is charged on?

IRAS’s BSD page (last updated 9 October 2026) sorts a benefit that comes with a purchase into three groups:

• May be deducted: a cash discount that is stated in the document to be stamped and given to the buyer on execution of the document, “and not later”. IRAS’s wording for the discount is “cash, non-post dated cashier’s order or cheque”. The discount may come off the purchase price when working out the duty, provided the “nett price is still reflective of market value”.
• Not deductible: a non-cash benefit stated in the document, for which IRAS gives the examples of a furniture voucher, rental guarantee, car or lucky draw.
• Not deductible: any benefit, cash or non-cash, not stated in the document to be stamped.

IRAS’s ABSD page (last updated 27 August 2026) answers an FAQ about a developer’s 15% direct cash discount that is stated in the document to be stamped in the same way: it may be deducted, provided the net price is still reflective of market value. The same page says BSD and ABSD are computed on the same figure, the higher of the price stated in the document and market value, so the answer applies to both.

Neither page says how close the net price must be to market value or gives a percentage. That test is IRAS’s to apply, so it is a question for your lawyer; the pages give no figure to rely on.

What does a S$40,000 benefit save? A worked example

Take an illustrative S$2,000,000 unit and a S$40,000 benefit offered two ways to a Singapore citizen buying a second residential property, so ABSD is 20% on the rates IRAS lists from 27 April 2023. For Route A, assume the discount is written into the document to be stamped, given on execution, and leaves a net price that reflects market value. The figures are invented for the arithmetic, not a developer’s offer.

Route A: S$40,000 written cash discount, given on execution

• Price charged to duty: S$2,000,000 less S$40,000 = S$1,960,000
• BSD: S$1,800 + S$3,600 + S$19,200 + S$20,000 + S$23,000 (5% of the last S$460,000) = S$67,600
• ABSD at 20%: S$392,000

Route B: S$40,000 furniture voucher, stated in the document

• Price charged to duty: S$2,000,000, because the voucher is not deducted
• BSD: S$1,800 + S$3,600 + S$19,200 + S$20,000 + S$25,000 = S$69,600
• ABSD at 20%: S$400,000

Route A saves S$2,000 of BSD and S$8,000 of ABSD, S$10,000 in all. Route B saves nothing, and neither would a benefit left out of the document.

Both prices sit inside the 5% BSD band, which runs from S$1.5 million to S$3 million when IRAS’s tiers (applying from 15 February 2023) are added up, so each S$1 of qualifying discount cuts BSD by 5 cents. ABSD falls by the buyer’s rate times the discount: on the same S$40,000, S$0 for a citizen’s first home, S$2,000 for a permanent resident’s first home (5%), S$12,000 for a permanent resident’s second home (30%) and S$24,000 for a foreigner (60%). This is our arithmetic from IRAS’s rates as read on 17 October 2026, and it holds only while they and the buyer’s profile stay the same.

To run your own price through IRAS’s tables, our free BSD and ABSD calculator takes one price: you choose which to enter, and it cannot tell you whether a benefit qualifies.

Two cautions. S$10,000 is the duty on S$40,000 of price, not the value of the benefit, so it does not show which offer is better; that depends on what the benefit is worth to your household. And ABSD is not always final: IRAS allows a refund in some cases, for example when a first home is sold within a set period, which our ABSD refund guide covers.

What four questions should you ask of a benefits clause?

Run each benefit in your paperwork through these, in order:

1. Is it cash? IRAS’s wording is “cash, non-post dated cashier’s order or cheque”. A furniture voucher, rental guarantee, car and lucky draw are IRAS’s examples of non-cash benefits. Our reading: “non-post dated” suggests that a post-dated cheque would not qualify, though IRAS does not spell this out.
2. Is it stated in the document to be stamped? IRAS says a benefit not stated in the document is not deductible, so a promise made at the showflat, in a brochure or in a message lowers the duty only if the document to be stamped itself states it. Which document is the one to be stamped is for your lawyer to say: IRAS notes that the first instrument executed for a sale and purchase carries the full duty and later documents for the same sale are not charged again. Our guide to what each option to purchase date starts covers the sequence.
3. Is it given on execution? IRAS’s words are “upon execution of the document (and not later)”. Our reading, not IRAS’s: a discount promised for a later date, for example on completion or as a credit against a later instalment, would not appear to fit that wording. IRAS’s pages do not address later credits, so ask your lawyer how one would be treated.
4. Does the net price still reflect market value? This sits on top of the other three. Neither page sets a threshold. Our reading: because duty is charged on the higher of the stated price and market value, a net price well below market value would not lower the duty base below market value.

If any answer is no, IRAS’s wording gives no deduction for that benefit, so the duty is worked out on the full price (or market value, if higher). A lawyer can confirm in writing which figure applies.

What happens if the paperwork does not match the deal?

IRAS’s FAQs are direct about documents and arrangements:

• Backdating: the BSD page says contracting parties cannot change the date of the instrument to avoid higher duty. The ABSD page says it is an offence under section 62 of the Stamp Duties Act to evade stamp duty by executing a document where facts and circumstances are not fully and truly set forth, with a fine of up to S$10,000, imprisonment of up to 3 years, or both.
• Arrangements: the Commissioner of Stamp Duties may disregard or vary arrangements meant to evade or reduce duty. For tax avoidance, the ABSD page adds a 50% surcharge on the additional duty, with further penalties of up to 4 times the outstanding amount if the duty and surcharge are not paid by the deadline.
• Underpayment and lateness: the ABSD page says inadequate or late payment of stamp duty is “tantamount to non-stamping” and penalties would apply. IRAS’s stamping deadlines page (last updated 5 February 2026) says to stamp a document before signing it and, if it is signed, within 14 days of signing in Singapore, or within 30 days of receipt in Singapore if signed overseas, to avoid a penalty.

Our reading: none of this suggests that a cash discount written into the document is a problem, since IRAS’s own FAQ says it may be deducted. The risk these FAQs describe lies in a document that does not set out the deal as actually agreed.

What should you ask your lawyer before you sign?

• Which document is the one to be stamped, and where is each benefit written in it?
• For a cash discount: the amount, the form it is paid in, the date, and the net price that will be stated.
• The duty worked out line by line, and the figure if the discount were not deductible.
• Each buyer’s ABSD profile on the date of purchase, and the rate that applies to the purchase.
• Whether any promised benefit is missing from the document, and what that means for the duty.
• The stamping deadline, and how the duty will be paid.

IRAS’s deadline is to stamp within 14 days of signing in Singapore, while the instalments described in our payment schedule guide, whose stage percentages are unverified, run through construction, so it helps to plan both together. For dated launch prices to test the arithmetic against, see our Lucerne Grand guide; nothing on this page says that project, or any other, offers a cash discount, voucher or guarantee.
