I have the AMEX Delta Platinum Card. They just changed it to get 1.5 points per dollar if I make purchases over 5K in one shot.
I was thinking of intentionally overpaying the IRS by 10K or 15K and then getting the refund, in order to get close to the 25K needed to get 10,000 MQM's and achieve status on Delta.
The way I figure it, at 1.5 points per dollar and a 1.87% charge from the cheapest IRS CC processor, I only need to value Delta miles at 1.247 cents a point to break even. I usually get more than that when I redeem miles. And for sure once I factor in the MQM's I'm doing fine.
What worries me is how the IRS will react to an overpayment and then refund that big. Do you think it will raise flags? Get me audited? I'm more worried about getting such a big refund than the initial overpayment.
Does anyone know if there are thresholds that cause them to be flagged? I know there's a 10K threshold for bank transfers that gets their attention. What about this??
