Why am I not getting tax credits for the social security tax and medicare in box 4 and 6 withheld on my 2017 W-2 and why ampaying taxes on our social security benefits?

[DoninGA · Accepted solution]

Social Security and Medicare taxes withheld on a W-2 are not reported on nor deductible on a tax return.  There is no age limit for the payment of FICA taxes on earned income.

Up to 85% of Social Security Retirement/Disability/Survivors benefits 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
