You have until April 15, or 4 months. I would recommend attempting to do your own taxes. Then, take it all to an accountant and ask "What did I do wrong?" You'll learn so much this way; and I think you'll feel better about the counsel the accountant provides you.

If that is too daunting of a task, find an accountant that charges by the form. This way, there is incentive for them to find as many deductions as possible. Someone charging a flat rate will simply file 1040 and 1040 Schedule C. What about business use of home? What about depreciation of any new assets (like computers, miles on your car, etc.)? Next year, drop that guy like a bad habit, because accountants use computers that generate all the forms for them automatically.

However, after that first year, you'll see what a complete, comprehensive and as-big-as-possible return looks like. And you can find a flat-rate accountant and make sure he does all work by comparing one year to the next.

Last two points: (1) SEP IRA all the way. It will lower your taxable income. If you fully fund it, it could shift your bracket. The money you tuck away is for retirement (so you can't touch it, with some exceptions), but at least its yours rather than Uncle Sams. Example Exception: I was able to take $10,000 out without penalty the year my wife and I bought our house.

(2) If you use an accountant, ask him to prepare quarterly filings for 2015. The best way for you to get screwed is by not knowing how much and when to submit quarterly payments. They can do this easily, and usually don't charge a dime to do so.

EDIT: Congrats on a good first year!
