CardUp extends 1.75% fee for tax payment to August, removes card exclusions

Buy miles from 1.07 cents each when paying your income tax this year, now including an extended offer from CardUp

CardUp IT2020 v4 MM

It’s been a bumper year for those of you settling your income tax bill by credit card to earn extra miles in 2020, with some of the most competitive deals we’ve ever seen from the card payment providers and the banks themselves.

One of those is our Mainly Miles reader offer with CardUp, allowing you to make this one-time payment for a fee of just 1.75% using most Singapore-issued Visa and Mastercards, though it was initially for payments made by 23rd June 2020.

The promotion has been extended

I only received my income tax bill from IRAS last week, and we’re aware that many of you are still waiting on yours to come through, so the good news is the CardUp offer isn’t going away so quickly.

The team have kindly extended our offer code for two more months, so it’s now valid until 25th August 2020, for payments due on or before 28th August 2020.

No more card exclusions

When this offer was first launched by CardUp it was not applicable for Citi or Standard Chartered credit cards, which instead had a 2.25% fee using the GET225 promo code.

For most of our readers that meant searching for an alternative option when using the following cards:

  • Citi ULTIMA
  • Citi PremierMiles
  • Standard Chartered X Card
  • Standard Chartered PBVI
  • Standard Chartered Visa Infinite

The good news here is that CardUp has removed these exclusions in this extension to the 1.75% fee offer, meaning you can use any Singapore-issued Visa or Mastercard when making your payment and still enjoy the discounted rate.

Payments must be scheduled by 25th August 2020.

This offer has the potential with some 1.6 mpd local earn rate cards to allow you to ‘buy’ miles of 1.07 cents each, a market-leading rate.

Even general spend cards at lower rates, like the UOB PRVI Miles Visa (1.4 mpd) come in at 1.23 cents per mile in cost terms.

What about the MM189TAX20 and MM199TAX20 codes?

If you used our first CardUp promo codes in early May 2020, with 1.89% or 1.99% fee rates, don’t worry.

The CardUp team should already have been in touch with you to offer additional discounts to make up for the difference in the fee you paid already, compared to the latest 1.75% special reader rate.

Amex income tax promo fee of 2.4%

As you may have noticed in the graphic above, CardUp is continuing to offer a discounted fee if you want to use your Singapore-issued American Express card to pay your income tax bill, at 2.4% fee (usually 2.6%).

Cost per mile

Here’s how the cost per mile stacks up for some popular miles-earning Visa and Mastercard credit cards in Singapore.

2020 Income tax payment
Visa / MC via CardUp
Card Miles per S$1 Cost per mile
1.75% fee
Citi Ultima Trans
1.6 1.07¢

HSBCviNEW.pngHSBC VI 1.0 1.72¢

* 1.4 mpd earn rate for the SCVI card is subject to a minimum spend of S$2,000 in the same statement cycle as your income tax payment. The income tax payment does count towards the minimum.

There’s some value here too for American Express cards, with the Platinum Charge card currently boasting a double miles promotional rate between now and 20th July 2020.

* Until 20th July 2020

As you can see you’ll want to avoid using the Amex KrisFlyer co-brand cards if you can – the cost per mile is too high to guarantee good value from your miles in most cases.

How to pay

The process is straightforward, to pay your income tax bill first select the ‘Taxes & Stamp Duty’ icon.


You then need to enter your payment amount as per the outstanding tax balance as shown in your IRAS Statement of Account.

Remember paying through CardUp is a one-off tax payment offer, so you won’t be able to pay IRAS by monthly GIRO instalment this way.


Next you’ll have to select your tax due date. Note that specific fixed periods are used each month depending on your IRAS bill due date to allow your payment to be processed in sufficient time, as explained here.


Your payment reference number is automatically pulled from the NRIC number registered on your CardUp account. This prevents any erroneous payments to the wrong tax accounts not tied to your own NRIC.

You are also required to upload an up-to-date copy of your Statement of Account, showing your Name, NRIC, Outstanding balance and date of outstanding balance for CardUp to verify your payment.


Finally it’s the all-important PROMO CODE, where you can enter one of the codes above – MM175TAX20 for eligible Visa and Mastercard payments and AMEXTAX24 for eligible Amex payments.


Remember you’ll be looking to use one of the following promo codes when making your payment if you can:

Other income tax payment methods

Before you take the plunge with CardUp, there are a number of other methods for earning miles when paying your income tax by credit card, some of which offer a lower cost per mile and/or offer you the flexibility of monthly GIRO payment.

One of those is taking advantage of this 1.5 mpd Citi PayAll offer for income tax payments with the Citi PremierMiles card.

Our guide 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.

Other CardUp offers

CardUp has also extended some of its offers for other personal payment types:

  • General Payments: 2.6% 2.25% extended until 31st December 2020 (code GET225)
  • Rent: 2.6% 1.9% extended until 31st December 2020

One of the options you’ll see in the full analysis of the best value income tax payment options for 2020 is ipaymy. That payment provider was the first to launch its 2020 income tax payment offer with the same fee of 1.75% for both new and existing users, though there are some card exclusions to be aware of.

These include Mastercards issued by Citi, OCBC and UOB, so look to CardUp for those options, otherwise you’ll pay a 2.25% fee with ipaymy.


Good news on two fronts from CardUp – an extension to our reader offer for a 1.75% fee when making your income tax payment plus the removal of card exclusions which unlock some Citi and Standard Chartered credit card options.

Though CardUp doesn’t support monthly GIRO payments to IRAS, if you usually pay by one-time instalment then it’s an option well worth considering.
