About the Individual Income Tax

The IRS and most states collect a personal income tax, which is paid throughout the year via tax withholding or estimated income tax payments.

Most taxpayers are required to file a yearly income tax return in April to both the Internal Revenue Service and their state's revenue department, which will result in either a tax refund of excess withheld income or a tax payment if the withholding does not cover the taxpayer's entire liability. Every taxpayer's situation is different - please consult a CPA or licensed tax preparer to ensure that you are filing the correct tax forms!
