If you have an IRAS tax bill to pay in Singapore, whether it be property tax, stamp duty or income tax, there’s a new offer from card payments provider CardUp with a discounted 1.8% admin fee offer for payments made between now and the end of March 2025, using locally-issued Visa cards.

This can reduce the cost per mile to as low as 1.11 cents in some cases – an attractive rate to ‘buy’ miles.

Here’s how the deal is structured.

1.8% fee for tax payments

This tax deal offers a 1.8% admin fee using promo code TAX18 and is running for payment due dates from now until 31st March 2025. To allow for processing time, you must schedule your payment by 26th March 2025 at 6pm Singapore Time, to be eligible.

The following tax payments to IRAS are eligible for the promotion:

• Personal and business property tax
• Personal stamp duty
• Personal income tax
• Business GST and corporate tax

TAX18

Fee: 1.8%

One-time or recurring payment New & Existing users All tax categories S$10,000 cap per month Singapore Visa cards Charge by 26th March 2025 Terms

There is no minimum payment, but the maximum per month is S$10,000. If your monthly payments using this promo code exceed S$10,000, CardUp’s regular 2.6% fee will apply to the amount over and above S$10,000.

Note that CardUp is restricting the offer to Singapore-issued Visa cards. A full list of the platform’s eligible miles-earning cards is available here.

Bear in mind that there will probably be a specific income tax promotion code offered by CardUp and other providers for income tax payment season, usually released around late March.

In recent years, this has allowed income tax payments at a discounted fee of 1.75% for Visa cards, and 1.99% for Mastercard payments, so look out for that.

What’s the cost per mile?

Here’s how the all-important cost per mile looks for some popular Visa credit cards issued in Singapore under this offer..

2025 Tax payment promo
Cost per mile

Card	Mpd	Cost per mile (1.8% fee)
Citi ULTIMA	1.6	1.11¢
DBS Insignia	1.6	1.11¢
UOB Reserve	1.6	1.11¢
DBS Vantage	1.5	1.18¢
UOB PRVI Miles Visa	1.4	1.26¢
SCVI	1.4*	1.26¢*
UOB VI Metal	1.4	1.26¢
DBS Altitude Visa	1.3	1.36¢
OCBC 90ºN Visa	1.3	1.36¢
OCBC Voyage Visa	1.3	1.36¢
Citi PremierMiles Visa	1.2	1.47¢
SC Journey Card	1.2	1.47¢

* For SCVI 1.4 mpd is subject to a minimum spend of S$2,000 in the same statement cycle, otherwise 1 mpd. CardUp payments do count towards the minimum.

Even with one of the widely-held 1.2 mpd cards like the Citi PremierMiles Visa, an effective cost per mile of 1.47 cents is quite competitive.

For those lucky enough to have 1.6 mpd earning cards, the cost per mile drops to an excellent 1.11 cents.

How it works

CardUp has a self-explanatory user interface for setting up payments, just be sure to input the promo code at the appropriate stage, as shown below.

Note that the regular 2.6% fee shows initially, but once you proceed to the payment stage the discount will be reflected.

You will also have to upload your IRAS tax statement, to verify the payment.

Terms and conditions

The terms and conditions for the TAX18 offer can be found here.

CardUp is offering new and existing customers using local Visa cards a discounted fee of 1.8% when making both one-time and recurring IRAS tax payments between now and the end of March 2025, allowing you to ‘buy’ miles from 1.11 cents each for a range of tax payment categories.

This is the cheapest current deal for tax payments, though we do expect other offers to appear in the coming weeks and months as personal income tax season will be upon us once again – so stay tuned for hopefully even better offers, also including Mastercard and Amex cards.
