The fiscal year for individuals and entities to report and pay income taxes is often known as the taxpayer's tax year or taxable year. Taxpayers in many jurisdictions may choose their tax year. Some federal countries, such as Canada and Switzerland, require the provincial or cantonal tax year to align with the federal year. In the United States, most states retained a 30 June fiscal year-end date when the federal government switched to 30 September in 1976. Nearly all jurisdictions require that the tax year be 12 months or 52/53 weeks. However, short years are permitted as the first year or when changing tax years.
