"This letter presents our estimates of the effects on the OASI and DI Trust Funds of enacting the temporary reallocation of the payroll tax rate proposed in the President's Fiscal Year 2016 Budget. We estimate this reallocation will equalize the projected years of reserve depletion for the two trust funds to 2033.... The President's proposal would increase the total (employee plus employer) payroll tax rate for the DI Trust Fund by 0.9 percentage points, from 1.8 to 2.7 percent, for calendar years 2016 through 2020. The payroll tax rate for the OASI Trust Fund would be reduced by an equal amount so that the total OASDI payroll tax rate for these years would be unchanged."
