EZ?! Count your blessings! Besides, it sounds like you set your W-4 perfectly. Sure it may seem like a windfall to get a large tax refund but once you've maximized your matching employer retirement contributions, your goal should really be to break even. If you're getting a refund, you've been loaning the government your money without interest. If you are going to say "yeah but it forces me to save a little" I would ask, how old [read; responsible] are you!? Much better in the long run to auto deduct the same bucks each pay period to an interest bearing 'personal year-end bonus account'. If your W-4 with holding falls a little short, you've got the shortfall covered. It you've over withheld, pay yourself a bonus or, better yet, add to a Roth IRA or your home down-payment piggy-bank. Of course, if you have itemized deductions above and beyond the Standard Deduction, claim 'em. If not, you DON'T want to start a 'business' just for expense write offs. The self-employment tax that a bona-fide sole proprietorship is required to pay will double your tax liability and, unless you have a whopping whole lot of verifiable legit deductions, you'd be better off pissing into the wind. Not to mention, be prepared to drop your drawers and grab your ankles for the IRS 'exam' as they ALWAYS audit a higher percentage of biz vs. personal returns for fraudulent write-offs. It always amuses me when folks recommend incurring $1.00 in additional expenses just to deduct $0.20... still $0.80 in the hole!
