Why is my Ssocial Securty being taxed

[19Dan53]

This year my $15,000 of my $1,7800 social is being taxable why?

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

The amount of your Soc Sec that is taxed is dependent upon your other (Joint) income (which can change from year to year).
