Did you work for an employer who withheld your taxes on your behalf, or were you self employed and paid your own estimate taxes throughout the year? It also depends how old your kids are too. Not to mention whether you own a house or had any major tax deductible expenses, deductions, or credits, and so on. I'd recommend seeking an accountant if your financial matters are pretty complex, and if you're doubtful or unsure on how to do it yourself. If it's pretty simple, you can probably get by on TurboTax or TaxAct yourself.
