AND
not to miss out on the potential for rollover,
You are at 11k short of the 50k needed for the 2nd bonus on the Delta Amex
If you spend 11k in 3 weeks, you will get 11k miles, 10k bonus miles & 10k MQMs
Value = 210$ + at least 300$ for the MQMs = 500$ min
Take out a 10k home equity loan for 3 months = 10k at 3% x 3/12 = 75$ cost
Go to officialpayments.com and pay the 10k for your taxes.
It does not all have to be federal, it can be your real estate taxes, your state taxes, estimated taxes etc etc even if an overpayment.
You will spend 235$ in fees and 75$ in loans fees= 310$ for 510$ value back.
Good luck
It is not worth paying taxes for the miles or points, but just like a Mileage run when you are close but short of a real useful target like 1k/PM/EXP, it is worth paying the fees for taxes. Usually a very bad idea, esp for DL, getting miles at 2.4c each is NOT a good idea.
