Treasury Yields Climb, Social Security Taxable Before Collection

Retirees face unexpected Social Security taxes from inflation-linked bond growth.

In brief

Retirees face unexpected Social Security taxes from inflation-linked bond growth. Retirees with inflation-protected bonds may see more Social Security taxed before receiving payments due to annual inflation adjustments. Originally reported by 24/7 Wall St..

Social Security Tax Trap for Retirees

Retirees with inflation-protected bonds face unexpected Social Security taxes from annual inflation adjustments.

“She chose inflation-protected Treasury bonds to keep her savings safe, but a quirk in the tax code means the IRS collects on income she cannot spend”

TIPS Create Paper Income

TIPS bonds generate income that grows with inflation but remains uncollected until tax time.

“TIPS protect against inflation by raising their principal as consumer prices rise. Her interest, paid twice a year at a fixed rate, is figured on that larger amount.”

IRS Taxes Inflation Growth Immediately

IRS Taxes Inflation Growth Immediately

The IRS taxes inflation adjustments as interest before cash is received, creating taxable income.

“IRS Publication 550 says anyone holding inflation-indexed debt such as tips must report any increase in the inflation-adjusted principal as original issue discount.”

Taxable Threshold Impact

An extra $7,200 in paper income can push retirees over Social Security tax thresholds.

“On $200,000 of tips, that adds about $7,200 of reportable income. None of it lands in her checking account.”

Social Security Taxable Calculation

The IRS adds half of Social Security benefits to other income to determine taxable portions.

“To decide whether social security is taxable, the irs adds one-half of the social security benefits to her other income.”

Thresholds Trigger Taxable Portion

Retirees above $25,000 in other income see up to 85% of Social Security taxed.

“IRS Publication 915 sets the starting threshold for a single filer at $25,000. Once her combined total passes the thresholds, a growing piece of her benefits becomes taxable.”

TIPS in Taxable Accounts

TIPS in taxable accounts create immediate taxable income that affects Social Security calculations.

“Her bonds create income she never uses. That income can also raise the share of her social security check that gets taxed.”

Tax Planning for Retirees

Retirees should check Form 1099-OID and separate bond yields, inflation adjustments, and tax impacts.

“Each year, she should check box 8 of her form 1099-oid before calculating her taxes.”

What matters most

Retirees with inflation-protected bonds may see more Social Security taxed before receiving payments due to annual inflation adjustments.
