Most tax preparers are honest, but some are engaging in refund fraud, identity theft or other illegal scams.

When using preparers make sure they:

Have a Preparer Tax Identification Number (PTIN) for 2015. This certifies the person is authorized to prepare federal tax returns.

Don't base their fees on your refund. And always have your refund sent directly to you or your bank account.

Can e-file returns. Tax professionals who prepare more than 10 returns must be able to file returns electronically.

Are available after April 15. You may need to contact your preparer if questions about your return arise.

Sign your return. Paid preparers are required to and must include their PTIN. They should also give you a copy of what she sent to the IRS.

And you should never sign a blank or incomplete return since you're legally responsible for the information. So check that there are no error and get all your questions answered before signing it.

If you think you've been had, report it to the IRS using Form 14157 and Form 14157-A.
