I retired last year, and started receiving social security payments.
Do I have to pay taxes on my social security benefits?
To determine whether any of your benefits are taxable, compare the base
amount for your filing status with the total of one half of your social security
payments plus all your income from other sources, including tax exempt interest.
If you are married and file a joint return, you must combine your incomes
and your social security and equivalent tier 1 railroad retirement benefits
when figuring the taxable portion of the benefits.
The taxable amount of the benefits is figured on a worksheet in the Form
1040 or 1040A instruction book, or in Publication 915, Social Security
and Equivalent Railroad Retirement Benefits. Refer to Tax Topic 423, Social
Security and Equivalent Railroad Retirement Benefits, for base amounts,
and additional information regarding taxability and reporting requirements.
