This is my very first post after lurking since around January 2015. I have a rather specific question that I haven't seen a good answer to.
I am self-employed with a highly variable income. I am not yet an LLC or S-Corp, so I pay quarterly estimated taxes as an individual. Every time I get paid, I set aside 35% for my eventual tax bill. When the time rolls around for me to make my quarterly tax payments, I pull from that amount I've saved, but since my income is going up, I am finding that I have more saved than what my tax advisor set me up with as a "safe estimate" payment plan for this year.
My question is, where is the best, most mustachian place to park the extra money I have saved over and above my "safe-estimate* payments?
I am looking at the various pre-paid cards that have 5% interest rates associated with them, but they seem a little dauntingly difficult to actually get the money back out again. I've seen them recommended for an emergency fund, but this is money I will most likely need in a year's time.
I am still in the debt-repayment part of growing my stache, so every little bit of extra money earned in interest is helpful for me.
Thank you very much for your advice!
