Rules and decisions to review
- The calculation generally considers one-half of benefits plus other income, including certain tax-exempt interest.
- Depending on the result, up to 85% of benefits may be included in taxable income. This does not mean an 85% tax rate.
- IRA withdrawals, pensions, investment gains and employment income can affect the calculation.
- Voluntary federal withholding on benefits or estimated payments may help cover the resulting tax. A deduction available to some older taxpayers does not repeal the Social Security taxation rules.
A practical example
A retiree who receives only Social Security may have a different result from a retiree who also takes a large traditional IRA distribution. The withdrawal can change the amount of benefits included on the return.
Records to gather
Gather Form SSA-1099, pension and IRA Forms 1099-R, investment statements and withholding totals.
Your next step
Project total annual income before changing Social Security withholding or taking a large retirement distribution. Review the taxable-benefit calculation alongside the rest of the return rather than examining benefits alone.
