CardUp has launched its income tax promotions for YA2024, and customers paying with a locally-issued Mastercard can enjoy a discounted 1.99% fee for payments scheduled by 31 August 2024.
This offer is valid for one-off payments only, and you could buy miles from 1.22 to 1.95 cents per mile depending on which card you hold. It’s a competitive price, but not the lowest possible- there’s a separate 1.75% offer for payments using Visa, available with the promo code MLTAX24.
Here’s how the two offers compare:
| Visa | Mastercard | |
| Code | MLTAX24 | MCTAX24 |
| Admin Fee | 1.75% | 1.99% |
| Schedule by | 31 Aug 24 | 31 Aug 24 |

CardUp users paying income tax can use the promo code MCTAX24 to enjoy a 1.99% fee, for payments scheduled by 31 August 2024 with due dates on or before 11 September 2024.
This code is valid for all locally-issued Mastercards. It can be redeemed once per customer, and only for one-off payments. If you want to take advantage of the interest-free instalments offered by IRAS, you’ll need to pay with a Visa using the MLTAX24 code, which is valid for both one-off and recurring payments.
Both new and existing CardUp users can use this promo code, but if you’re a new user, refer to the box below for a special offer.

If this is your first time using CardUp, use the code MILELION to save S$30 off your first transaction with no minimum spend required. This allows you to earn free miles on a payment of up to S$1,154 (based on CardUp’s regular admin fee of 2.6%). You can subsequently use the MCTAX24 code to pay the rest of your balance, since this code is valid for both new and existing customers. |
What’s the cost per mile?
Here’s the cost per mile for various Mastercards in Singapore, given the earn rates and a 1.99% admin fee.
| Card | Earn Rate | Cost Per Mile (1.99% fee) |
 Citi ULTIMA MC |
1.6 mpd | 1.22¢ |
 UOB PRVI Miles MC |
1.4 mpd | 1.39¢ |
 OCBC 90°N MC |
1.3 mpd | 1.50¢ |
 Citi Prestige |
1.3 mpd | 1.50¢ |
 Citi Premier Miles |
1.2 mpd | 1.63¢ |
 KrisFlyer UOB |
1.2 mpd | 1.63¢ |
 BOC Elite Miles |
1 mpd | 1.95¢ |
| 💳 OCBC customer? |
| OCBC 90°N Mastercard cardholders take advantage of a lower fee, provided they’re new to CardUp. Use the code OCBC90N15 for 1.5% fee, valid for first-time payments only. |
Remember, both the tax payment amount and the CardUp fee are eligible to earn miles.
For example, someone who pays a S$1,000 tax bill via CardUp would pay S$1019.99 after fees. If he uses a 1.4 mpd card, he will earn 1,428 miles (ignoring rounding), for which he has paid a fee of S$19.99. The cost per mile is therefore 1.39 cents each.
Depending on what card you use, the cost per mile can start from as low as 1.22 cents each. This isn’t the absolute lowest price you can manage— for that, you’d need to pay with a 1.6 mpd Visa card and a 1.75% fee — but it’s still quite compelling. Assuming your tax bill is large enough, you could be buying a Business Class ticket to Japan or South Korea for just over S$1,269 plus taxes (Business Saver @ 104,000 miles @ 1.22 cents each).

I’m putting the final touches on The MileLion’s Income Tax Guide 2024, which gives a rundown of options for earning miles when paying income tax with credit cards.
It should go live this weekend, so stay tuned!
Conclusion
CardUp is now offering a 1.99% fee with the code MCTAX24 for income tax payments made with Mastercard, for payments set up by 31 August 2024. However, the code is only valid for one-off payments, and you can get an even lower 1.75% fee with Visa.
Therefore, most miles chasers should prioritise the Visa code, unless they’re trying to meet the minimum spend for a welcome offer with a Mastercard.
Cpm using MCs – meh
