Grab the appropriate paper work that usually comes in the mail and fill in the blanks. Then again, sometimes it is not so simple. That's why I love Accountants. They can whip through all the tax laws, tax breaks, income brackets, deductions, mumbo-jumbo and riggamarole. I love those deductions.
Accountants make it seem so easy.
Ignorance is no excuse, I guess. There is absolutely nothing wrong with leaving this serious matter in the trusted hands of your favorite neighborhood Accountant. They want to figure out how to get you a refund. It is good for everyone. They like their job so no paper cuts there.
