However, even after the Revolutionary War and the adoption of the . Constitution, the main source of revenue for the newly created states was money received from customs and excise taxes on items such as carriages, sugar, whiskey, and snuff. Ine tax first appeared in the United States in 1862, during the Civil War. At that time only about one percent of the population was required to pay the tax. A flatrate ine tax was imposed in 1867. The ine tax was repealed in its entirety in 1872. Ine tax was a rallying point for the Populist party in 1892, and had enough support two years later that Congress passed the Ine Tax Act of 1894. The tax at that time was two percent on individual ines in excess of $4,000, which meant that it reached only the wealthiest members of the population. The Supreme Court struck down the tax, holding that it violated the constitutional requirement that direct taxes be apportioned among the states by population (pollock v. farmers39。s gross ine to arrive at an adjusted gross ine, from which additional deductions are taken to arrive at the taxable ine. Once the amount of taxable ine has been determined, tax rate charts determine the exact amount of tax owed. If the amount of tax owed is less than the amount already paid through tax prepayment or the withholding of taxes from paychecks, the taxpayer is entitled to a refund from the IRS. If the amount of tax owed is more than what has already been paid, the taxpayer must pay the difference to the IRS. Calculating the gross ine of restaurant employees whose ine is partially derived from gratuities left by customers has led to disputes with the IRS and employers over how much they should contribute in federal insurance contribution act (fica) taxes. Although customers pay these tips directly to employees, federal law deems the tips to have been wages paid by the employer for FICA tax purposes. Employers are imputed to have paid large sums of m
