Note: CardUp has now extended its promo code for Mainly Miles users to 23rd August 2020, and also removed Citi and Standard Chartered exclusions from the offer so all Singapore-issued Visa and Mastercards are now eligible.

Another batch of IRAS Income Tax Notices of Assessment were sent out on Monday for your 2019 earnings. In fact I just got my own statement this week, which is payable by mid-July 2020.

If you’re in the same boat you will no doubt want to consider the various ways to earn the most miles with your payment this year, but don’t wait too long to think about it because one valuable option is set to disappear just a week from now.


CardUp’s 1.75% fee offer

CardUp’s special offer for Mainly Miles readers this year means you can enjoy a discounted 1.75% fee on income tax payments using most Singapore-issued Visa and Mastercard credit cards.

This offer allows you to buy miles from as little as 1.07 cents each when settling your income tax bill with IRAS.

As many of you will already know, ipaymy is also offering a 1.75% promotional rate for income tax payments this year. That offer runs until 31st July 2020, so what’s the rush to use CardUp?

Well ipaymy has some exclusions on the Mastercard side under its promotional offer, specifically for Citi, OCBC and UOB Mastercards.

That means there are three miles earning cards exclusive to CardUp for income tax payments this year (at a 1.75% fee):

Card MC UOB PRVI Miles Mastercard

1.23 cpm
Card 2 OCBC 90°N Mastercard

1.43 cpm
Card Trans KrisFlyer UOB Mastercard

1.43 cpm

If you’re planning to use one of these cards to settle your income tax bill this year then don’t forget to complete your payment using the MM175TAX20 code through CardUp before 23rd June 2020. Otherwise the rate will revert to 2.25% until 30th June, then 2.6% thereafter.

Full terms and conditions for the MM175TAX20 promo code are available here.

Another CardUp offer this year is for income tax payment using American Express cards with a 2.4% fee.

CardUp IT2020 Amex

This one runs for an additional month and is valid until 23rd July 2020, before reverting to the usual 2.6% fee.

Here are a few Amex options you can take advantage of with CardUp this year for income tax payment at the discounted 2.4% fee, though these are generally more expensive than the Visa and Mastercard options.

Card Amex Platinum Charge

1.50 cpm
Card Amex Big UOB PRVI Miles Amex

1.81 cpm
AscendCC small Amex KrisFlyer Ascend

1.95 cpm
AMEXKFblue Amex KrisFlyer

2.13 cpm


You can still use ipaymy’s promo code for a 1.75% rate on income tax payments until 31st July 2020, however do note that ipaymy does not support payments made using the cards we listed earlier – the UOB PRVI Miles Mastercard, OCBC 90°N Mastercard or KrisFlyer UOB Mastercard at the promotional rate (you’ll pay 2.25% instead), nor does it allow you to use Amex cards.

On the flip side there are some payment options offered by ipaymy but not supported by CardUp at their 1.75% promotional rate this year:

  • Citi ULTIMA
  • Citi PremierMiles (though this PayAll deal is cheaper)
  • Standard Chartered X Card
  • Standard Chartered PBVI
  • Standard Chartered Visa Infinite (though the card’s own facility is cheaper)

Comprehensive guide

Before you commit to any particular income tax payment method, don’t miss our comprehensive guide to all the options available this year.

This will help you navigate to which option is best value for the credit cards you hold, including using some of the bank’s own direct payment methods, which can also make sense in some cases.

  1. Is the discounted fee only applicable for a one-off 1st time payment to IRAS ? or do both CardUp & ipaymy support monthly giro deductions at their respective advertised discounted rates ?

  2. Does the credit card limit override the amount we can use ipay or cardup to pay income tax? For example, if my credit card limit is $10k and my income tax is $15k, does that mean I can only use ipay or cardup to pay $10k and the balance by cash?

    1. Yes the credit card limit will come into play. CardUp will only pay the whole IRAS NoA balance so that transaction would be rejected. I’m not sure if ipaymy allows partial payment.

      One option is to ask for a credit limit increase or pre-pay your credit card balance before making the transaction.

      For example pay $5,000 into your credit card so the balance is -$5,000, then a $15,000 transaction will be approved.
