Taxes owed for contracting in MN
I am doing contract work in MN. I have not been paying estimated taxes, but I have additional taxes taken out of my paycheck from my full-time job. First question is will I get penalized for not paying estimated taxes? Second question is how do I estimate how much I'm going to owe? Trying to make sure I'm having enough deducted right now so I don't have to pay in.
Thank you!
