Do you have one of those awesome 2% cash back credit cards (CapitalOne Venture, Barclay Arrival+, Chase Saphire Preferred, etc.)?
Do you owe some US tax money for last year or need to make estimated tax payments?
Try this link out. If you use the first link, they’ll charge you a 1.87% fee but then you credit card will pay you 2%. I hope for your sake that only amounts to some change in your pocket. The less you gain on this exchange, the less you had to pay in taxes.
