CardUp
from 1.73% feeMost Visa / Mastercard cards (some exclusions)
CardUp lets you charge bills that don't normally take cards — income tax, rent, insurance, school fees — to your credit card for an admin fee. You earn the card's miles or cashback; whether it's worth it depends on whether your reward rate beats the fee.

How it works
Schedule a payment in CardUp and pay the biller from your credit card for a percentage admin fee (lower with a promo code). For a miles card, the play works when miles-value-per-dollar exceeds the fee — e.g. a 1.4 mpd card at 1.5¢/mile earns 2.1¢/$ against a ~1.75% income-tax fee.
- •Standard fee rises 2.6%→2.9% on 13 Jun 2026 (one-off + recurring); scheduled payments charged on/after that date pay the new rate.
- •Fees are promo-code driven and change seasonally — check the current code before paying.
- •DBS/UOB cards on the American Express network stopped earning via CardUp in Mar 2026 — use their Visa/Mastercard variant.
- •Worth it only when your card's reward value per dollar beats the admin fee.
