all states impose interest charges on late payments of tax, and generally also on additional taxes due upon adjustment by the taxing authority. Individual income tax Forty-three states impose a tax on the income of individuals, sometimes referred to as personal income tax. State income tax rates vary widely from state to state. States imposing an income tax on individuals tax all taxable income (as defined in the state) of residents. Such residents are allowed a credit for taxes paid to other states. Most states tax income of nonresidents earned within the state. Such income includes wages for services within the state as well as income from a business with operations in the state. Where income is from multiple sources, formulary apportionment may be required for nonresidents. Generally, wages are apportioned based on the ratio days worked in the state to total days worked. All states that impose an individual income tax allow most business deductions. However, many states impose different limits on certain deductions, especially depreciation of business assets. Most states allow non-business deductions in a manner similar to federal rules. Few allow a deduction for state income taxes, though some states allow a deduction for local income taxes. Six of the states allow a full or partial deduction for federal income tax. In addition, some states allow cities and/or counties to impose income taxes. For example, most Ohio cities and towns impose an income tax on individuals and corporations. By contrast, in New York, only New York City and Yonkers impose a municipal income tax. States with no individual income tax Eight U.S. states do not level a broad-based individual income tax. Some of these do tax certain forms of personal income: Alaska – no individual tax but has a state corporate income tax. Alaska has no state sales tax, but lets local governments collect their own sales taxes. Alaska has an annual Permanent Fund Dividend, derived from oil revenues, for all citizens living in Alaska after one calendar year, except for some convicted of criminal offenses. Florida – no individual income tax but has a 5.5% corporate income tax. The state once had a tax on "intangible personal property" held on the first day of the year (stocks, bonds, mutual funds, money market funds, etc.), but it was abolished at the start of 2007. Nevada – no individual or corporate income tax. Nevada gets most of its
