Social security and Medicare taxes have different rates and only the social security tax has a wage base limit. The wage base limit is the maximum wage subject to the tax for the year. Determine the amount of withholding for social security and Medicare taxes by multiplying each payment by the employee tax rate. There are no withholding allowances for social security and Medicare taxes.
In determining whether your Social Security benefits are subject to income tax, the IRS uses combined income. To figure your combined income, start with your adjusted gross income, and then add your nontaxable interest and dividends plus half of that year's Social Security benefit amount.he Social Security Administration does not count traditional IRA distributions as income in calculating your annual benefit amounts, but the Internal Revenue Service does count the same distributions in figuring your tax liability. Neither agency counts Roth IRA distributions as income.
