Why are you getting a refund? Trump doesn’t need a loan.
I make quarterly payments and keep my taxable income as low as possible. I rarely have any Federal income tax liability until 3Q and can usually extend it all the way to 4Q when I recognize about 75% of my annual income. I then write a check for about 92% of the annual total tax as the 4Q estimated tax payment and settle the balance on April 15th.
Keep your money working for you.
