I'm a few years out of college now. I've filled out my W4 accurately and I still get a tax refund every year of a pretty sizable sum. The thing is, I have student loans and I would much rather have been paying that extra money on a monthly basis (to prevent interest charges) than have given it to the government to 'hold' for me.
I've spoken to the HR department about lowering my tax deductions and they suggest putting more exemptions on my W4. However this seems off because I would essentially be purposely filling out a form incorrectly. Also, I don't see anything on this one sheet to take into consideration my student loan interest deduction, which is a large part of where my refund comes from.
How do I pay my taxes correctly throughout the year so that I don't owe or receive any money when I file?
