Answer: 40.65%
Step-by-step explanation:
The Effective Marginal Tax rate is the amount of a person's additional dollar in income that is taken as taxes.
This means therefore, that all the taxes applicable to an additional dollar are added up to find the Effective Marginal Tax Rate.
= Marginal tax rate + State income tax rate + City income tax rate + Social Security and Medicare
= 28 + 4 + 1 + 7.65
= 40.65%
