CardUp: New and Existing Users Get Discounted 1.75% Fee For Property Tax Payment
Until 31st January 2024, CardUp has a promo that works for existing users: get a reduced fee of 1.75% for making property tax payment with code SETHPROP175. This represents an opportunity to buy miles for cheap, or earn the difference between your cashback card and the fees paid.
While new users can also use this promo, you should use the new user promo first before using this code for property tax payment.

New users – get free cashback/miles for your first payment; guide available
If you are totally clueless to what CardUp can do, I have written a guide to introduce newcomers to the payment service. Also, new users get a promo code for fee waiver on their first payment, so it is an opportunity to get some miles and cashback for free.
Miles buying opportunity from 1.07 cents onwards
With the reduced fee comes cheaper cost to procure miles at:
| Earn Rate | Card(s) | Cost Per Mile (1.75% service fee) |
| 1.6 miles per dollar | DBS Insignia, Citi Ultima | 1.07¢ |
| 1.5 miles per dollar | DBS Vantage | 1.15¢ |
| 1.4 miles per dollar | UOB PRVI | 1.23¢ |
| 1.3 miles per dollar | Citi Prestige, DBS Altitude, OCBC 90°N | 1.32¢ |
| 1.2 miles per dollar | Citi PremierMiles, StanChart Journey | 1.43¢ |
My personal barometer is to buy miles at below 1.25 cents each as far as possible. CardUp’s promo hence makes sense for cards that earn at least 1.4 miles per dollar each.
Given that many miles cards require you to redeem in blocks of 10,000 miles, buying some miles above 1.25 cents each isn’t too bad an idea if you are short a few miles.
Cashback arbitrage
With a relatively low fee, you also get the chance to earn the difference between some card’s cashback rate and the 1.7% fee charged.
| Card | Cashback Rate |
| OCBC FRANK | Roughly 3.13%* |
| Bank of China Family | 3% |
| Maybank Platinum Visa | 3.33% (quarterly payments required) |
Good chance to score some rewards
For users who are already using CardUp to score card rewards, having fee discounts are always welcomed. Those who have yet to try the service out should really get started. (Cheap) business class beckons!
