Should i have any withholding on my social security for 2018? All my other income will remain the same as 2017, but i will be receiving a full 12 months of SS in 2018.

Maybe, it depends on the rest of your income. Your social security may be taxable up to 85% or not at all depending on how much other income is reported. You can withhold the first year if you want to be safe and either discontinue or withhold less depending on how the year end looks.

Social Security Disability income can be taxable based upon the other income that is reported on your tax return.

Up to 85% of Social Security becomes taxable when all your other income plus 1/2 your social security reaches:

• Married Filing Jointly - $32,000
• Single or Head of Household - $25,000
• Married Filing Separately - 0
