There's no need to take a college-level course; H&R Block ( HRB), Jackson Hewitt ( JTX) and other firms offer classes that tell you all you need to know about taxes. Best of all: The cost of the course is deductible. Here are five reasons to take a tax class before next year's filing season: Learn about tax breaks you're missing: You probably missed out on deductions this year because you didn't save the necessary documents.

Once you understand common tax terms, you'll realize how easy it is to complete your filing yourself. Earn extra income: If you pass the course, you can earn extra money by preparing other people's taxes. These tax chains usually offer the courses to recruit and train potential employees.
