Did you change your filing status from Married Filing Jointly to Married Filing Separately? If so, that will cause your Social Security benefits to become 85% taxable.
The other reason could be a slight increase in income could have put you into the 85% taxable from the 50% taxable. Sometimes only a few dollars will make a difference.
If you fall into the following, 85% of your social security is taxable income
- Single with income above $34,000
- Married Filing Jointly with income above $44,000
- Married Filing Separate regardless of income
If you fall into the following, 50% of your social security is taxable income
- Single with combined income between $25,000-$34,000
- Married Filing Jointly with combined income between $32,000 and $44,000
Your combined income is calculated by adding your
- AGI plus
- Nontaxable Interest plus
- 1/2 of your social security Benefits
