Take a class. Boost your tax refund by up to $2,000 just by getting educated. You can learn a new career, update your job skills, or take a class on anything you want just for the heck of it. If your income is moderate you may be eligible for the Lifetime Learning Credit as well as college credits. You can claim a tax credit of 20% of all your tuition expenses, so taking courses that cost $500 in tuition will boost your tax refund by $100. You don’t need to be on track for a degree – the cost of any class that you take at the college level is eligible for the credit.
