My wife gets social security disability and I need to know if I need to even have her on my tax return?

If you are legally married and living together you have to file as Married Filing Jointly or Married Filing Separately.  You should be filing as Married Filing Jointly even if one spouse has little or no income.

She would have received a Form SSA-1099 for the disability payments.  They have to be reported on a tax return.

To enter Social Security benefits reported on form SSA-1099

• Click on Federal Taxes (Personal using Home and Business)
• Click on Wages and Income (Personal Income using Home and Business)
• Click on I'll choose what I work on (if shown)
• Scroll down to Retirement Plans and Social Security
• On Social Security (SSA-1099, RRB-1099), click the start or update button

Or enter ssa-1099 in the Search box located in the upper right of the program screen. Click on Jump to ssa-1099

• Married Filing Jointly - $32,000
