So why would you want to get such a large refund? I have never understood. Why wouldn't you want that money on your paycheck all through the year? Why not get it and put it into a savings account and earn a nice bit of interest instead of letting the government hold onto it for free? I'm not being mean or anything, just asking an honest question. It's up to everyone what they do with their own money but I think a lot of people don't quite get how the tax system works and think they HAVE to have a certain amount taken out of their paychecks and then they HAVE to wait until the end of the year to get it back. If that's what you like to do then fine, but it has never made much sense to me personally.
I pay a TON of tax and I do an estimate at the beginning of each year so I can get my withholdings almost dead on and get the largest paycheck possible. I want my money, I don't want the government holding onto any more of it than they have to. I get punished enough for working my ass off and not having kids or many other deductions, I'll be damned if I let them hold onto thousands more of my dollars. But that's just me, I'm an accountant and I want full control of my money at all times.
