What types of taxes are commonly withheld from employee paychecks?

The correct answer is A, as federal and state income taxes are indeed the main types of taxes withheld from employee paychecks. Employers are required to deduct these taxes from employees' earnings to satisfy tax obligations for both the federal government and state authorities.

Federal income tax withholding is based on the employee's earnings and the information provided on their W-4 form, while state income tax withholding varies by state and is similarly based on earnings, filing status, and allowances claimed. This process ensures that employees effectively pay their income taxes gradually throughout the year rather than in a lump sum at the end of the tax year.

The other types of taxes mentioned, such as sales and property taxes, are not directly withheld from employee paychecks. Instead, sales taxes are collected at the point of sale when goods and services are purchased, and property taxes are levied on real estate properties. Investment and capital gains taxes relate to income earned from investments rather than earned income from employment, and gift and estate taxes pertain to transfers of wealth and assets, not regular income. Thus, they do not apply to paycheck withholding.
