The Social Security Administration says most won’t pay federal income taxes on their benefits. But Congress didn’t directly exempt those payments from taxes.

The emails say nearly 9 in 10 Social Security beneficiaries won’t pay income taxes on their benefits in the future. But the Trump tax law did not directly address Social Security.

The Social Security Administration reportedly sent out an email claiming the policy bill “eliminates federal income taxes on Social Security benefits for most beneficiaries”—but that’s not true.
