Credit Cards Deals

CardUp extends 1.75% fee for income tax payment to October

You can continue to 'buy' miles from 1.07 cents each when paying your income tax this year, now including an extended reader offer from CardUp

It’s been a great 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. This was initially for payments made by 23rd June 2020, then extended to 25th August 2020.

The promotion has been extended further

We know that some of you are still waiting on your IRAS Notice of Assessment 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 26th October 2020, for payments due on or before 29th October 2020.

No 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, however these restrictions were lifted in June 2020.

That means you can continue to use any Singapore-issued Visa or Mastercard when making your payment and still enjoy the discounted rate.

Payments must be scheduled by 26th October 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.

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 MM175TAX20 for Visa and Mastercard payments.


Remember you’ll be looking to use the following promo code 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.
