To calculate your taxable income, add up all income earned in the calendar year, including items such as salary, investment gains and rental income. Your tax liability is then reduced by adjustments to income, deductions and exemptions.

If you are not repaid, your Form W2 will reflect the full amount actually withheld. If you claim exemption from withholding, your employer will not withhold federal income tax from your wages. The exemption applies only to income tax, not to Social Security or Medicare tax.

You can easily find cars for sale by owners online. Autotrader, Hertz Car Sales, Craigslist, CarDaddy, Edmunds, eBay and Cars.com are some popular websites selling used cars.
