Before the passage of the tax bill, 64% of seniors didn’t pay taxes on their Social Security benefits, according to a June report from President Donald Trump’s Council of Economic Advisers. Under the new legislation, 88% won’t pay taxes on those benefits, the report estimated.

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.

The bill doesn't eliminate taxes on Social Security, but rather introduces a temporary deduction that beneficiaries can claim to lower their federal income tax.
