If you need extra money but don't want a staff job, freelance work may be the answer. These days, companies hire freelancers for everything from writing and design to delivery and sales.

You usually don't get benefits, but can often set your own schedule and may even be able to work from home. The pay is self-employment income, and is viewed differently than normal wages by the IRS. You'll need to file specific tax forms with your annual return – and, depending on what you earn, you might need to submit quarterly tax payments. On the plus side, you can deduct many of your expenses, and may qualify for the home office deduction.
