Particularly in times of change like getting married, moving, changing jobs, and such it is often worth the money to meet with a CPA for some tax planning. If you don't have rental property, six part-time jobs, and a small business, it shouldn't take longer than a couple of appointments with a tax planner. Look for an older, experienced CPA with a very active individual income tax prep. practice, but don't go to some guy who ONLY does income tax. Now that the year is done, there isn't much you can really do about it, except maybe a last minute IRA contribution if you have some extra cash to stash.
When i was working two jobs and had a very predictable income stream, i managed to keep my federal and state income tax refunds under $5 for years. That means uncle fed didn't get to borrow my money all year for free.
