Tax preparation can be a daunting task, especially if you manage investments or rental property. While there are more and more do-it-yourself options for filing your taxes, working with a pro can help you save the most money while giving you the peace of mind that every detail is covered. However, it’s important to do your research before hiring a tax preparer.

For starters, you’ll want to choose a professional who’s properly certified in their field. A Preparer Tax Identification Number (PTIN) actually requires very little effort or experience to obtain, so make sure you choose someone with the best credentials. A CPA or a participant in the IRS’ Annual Filing Season Program has to undergo significant training and ongoing education, so you can rest assured you’re getting the experience and insight you need.
