<prompt> Human: Ive been thinking about the pros and cons to changing my W-4 to allow me to take less out for taxes. I know some people like to over pay and have the windfall ever year, while others like my sisters boyfriend. Hes a cpa like to pay exactly whats due reason being its stupid to over pay what are some benefits and draw backs to doing that? If it helps. My current financial goal is to pay off a 3100 dollar credit card. Could the extra money help in the long run or is it better to wait for the tax return every year?  <response>: I knew a guy who would withhold a ton of money, it was the ONLY way he could save, and every year hed get a large check each tax season 5-6K when I knew him 10 years ago. He knew that he had little discipline to put the money away, and that his wife would usually grab extra too.He credits this saving plan with how he was able to take his kids to Florida every year for 20 years.On the other side is me, I have them withold exactly what I owe, often times I will owe a couple of bucks because I sold some stock or even just from bank interest. Yeah, its painful to write a check every year especially if its a few hundred, but I think Id rather have that then have 100-200mo missing from my net paycheck going off to the government to be returned--with no interest--the next year.
