The form that the government requires a taxpayer to file with the appropriate official by a designated date to disclose and detail income subject to taxation and eligibility for deductions and exemptions, along with a remittance of the tax due or a claim for a refund of taxes that were overpaid.
The federal and state governments specify the deadlines for filing tax returns without incurring any additional interest or penalties for lateness. For most income taxpayers, the deadline of April 15 of the year following the close of the tax year for which the report is filed applies to both federal and many state returns. For persons who have made taxable gifts, the federal gift tax return is due annually on or before April 15 of the year following the tax year (as opposed to the former requirement of quarterly filing). For executors or administrators of estates that owe estate tax, a federal estate tax return must be filed within nine months of the date of death of the decedent. States may have comparable deadlines for gift and estate tax returns.
n. the form to be filed with a taxing authority by a taxpayer which details his/her/their income, expenses, exemptions, deductions, and calculation of taxes which are chargeable to the taxpayer. (See: tax)
