This could happen for multiple reasons:
- If payments made to you were subject to withholding of Social Security and Medicare taxes, they would be reported on a W-2 rather than the 1099-R.
- Workers compensation and Department of Veterans Affairs payments are generally tax exempt and wouldn’t get reported on the 1099-R.
- The payer might not have been required to calculate taxable income for you, or it didn’t have enough information to do so. Credit Karma Tax can help you determine the taxable amount with just a few questions.
