Nope, not so fast. Do your research before making claims, please. For example, if you have to pay $15K in taxes, you can sign up for a Chase Ink Business Preferred card, pay the $15K+1.85% = $15277, get the 100K bonus + 1X points on the $15277, which puts you at 115277 points, which is worth 1.25x in travel, which puts you at $1440 worth of air tickets or $1152 worth of cashback. Subtract the $277 extra you paid, subtract the $95 annual fee for one year (before which you'll cancel the card of course), and that leaves you with a net return of $1068 in air tickets or $780 in cash. There are quite a few other cards that you can come out ahead in as well, depending on how much tax you owe. And yes, I did this.
