1. Chart of Various Fiscal Years

2. Tax Year

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.^[1] 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.^[2] However, short years are permitted as the first year or when changing tax years.^[3]

Most countries require all individuals to pay income tax based on the calendar year. Significant exceptions include:

• Australia: individuals pay income tax based on the financial year of 1 July until 30 June.^[4]
• United Kingdom: the tax year for individuals begins on 6 April. This is due to Britain historically having a calendar year starting on Lady Day (25 March) in the Julian calendar, which translated to 5 April when the Gregorian calendar was adopted in 1752, and which then became 6 April in 1800. (In 1900 keeping the tax year synchronised to the Julian calendar was abandoned).
• United States: individuals may (but rarely do) elect any tax year, subject to IRS approval.^[5]

Many jurisdictions require that the tax year conform to the taxpayer's fiscal year for financial reporting. The United States is a notable exception: taxpayers may choose any tax year, but must keep books and records for such year.^[2]

3. Operation in Various Countries/region

In some jurisdictions, particularly those that permit tax consolidation, companies that are part of a group of businesses must use nearly the same fiscal year (differences of up to three months are permitted in some jurisdictions, such as the U.S. and Japan), with consolidating entries to adjust for transactions between units with different fiscal years, so the same resources will not be counted more than once or not at all.

3.1. Afghanistan

In Afghanistan, the fiscal year was changed from 1 Hamal – 29 Hoot (21 March – 20 March) to 1 Jadi – 30 Qaws (21 December – 20 December) in 2011.^[6] The fiscal year runs with the Afghan or Solar Hijri calendar, because of the differing cycle of leap years in the Gregorian and Afghan calendars, there can be slight differences in the start date of fiscal (and calendar) years. As shown in the chart below, leap years will coincide in 2020 and 2024 but will desynchronize with the Gregorian calendar having a leap year in 2028 as opposed to the Afghan calendar's leap year of 2029.

3.2. Australia

In Australia , a fiscal year is commonly called a "financial year" (FY) and starts on 1 July and ends on the next 30 June. Financial years are designated by the calendar year of the second half of the period. For example, financial year 2017 is the 12-month period ending on 30 June 2017 and can be referred to as FY2016/17. It is used for official purposes, by individual taxpayers and by the overwhelming majority of business enterprises.^[4] Business enterprises may opt to use a financial year that ends at the end of a week (e.g., 52 or 53 weeks in length, and therefore is not exactly one calendar year in length), or opt for its financial year to end on a date that matches the reporting cycle of its foreign parent. All entities within the one group must use the same financial year.

For government accounting and budget purposes, pre-Federation colonies changed the financial year from the calendar year to a year ending 30 June on the following dates: Victoria changed in 1870, South Australia in 1874, Queensland in 1875, Western Australia in 1892, New South Wales in 1895 and Tasmania in 1904. The Commonwealth adopted the near-ubiquitous financial year standard since its inception in 1901.^[9] The reason given for the change was for convenience, as Parliament typically sits during May and June, while it was difficult for it to meet in November and December to pass a budget.^[9]

The Financial year is split into the following four quarters^[10]

Companies following Indian fiscal year get to know their economical health on 31 March of every Indian financial or fiscal year.

The current fiscal year was adopted by the colonial British government in 1867 to align India's financial year with that of the British Empire.^[22][23] Prior to 1867, India followed a fiscal year that ran from 1 May to 30 April.^[24]

In 1984, the LK Jha committee recommended adopting a fiscal year that ran from 1 January to 31 December. However, this proposal was not adopted by the government fearing possible issues during the transition period.^[24] A panel set up by the NITI Aayog in July 2016, recommended starting the next fiscal year from 1 January to 31 December after the end of the current five-year plan.^[25]

The year of assessment for individuals covers twelve months, 1 March to the final day of February the following year. The Act also provides for certain classes of taxpayers to have a year of assessment ending on a day other than the last day of February. Companies are permitted to have a tax year ending on a date that coincides with their financial year. Many older companies still use a tax year that runs from 1 July to 30 June, inherited from the British system. A common practice for newer companies is to run their tax year from 1 March to the final day of February following, to synchronize with the tax year for individuals.

Although United Kingdom corporation tax is charged by reference to the government's financial year, companies can adopt any year as their accounting year: if there is a change in tax rate, the taxable profit is apportioned to financial years on a time basis.^[61]

A number of major corporations that were once government-owned, such as BT Group and the National Grid, continue to use the government's financial year, which ends on the last day of March, as they have found no reason to change since privatisation.

The 5 April year end for income tax reflects the old civil and ecclesiastical calendar under which New Year began on 25 March (Lady Day). The difference between the two dates is accounted for by the eleven days omitted when Great Britain converted from the Julian Calendar to the Gregorian Calendar in September 1752. At first sight the addition of eleven days to 25 March results in a tax year beginning on 5 April. However, the tax year previously actually began on 26 March. The taxes charged by the year (Land Tax and Window Tax) applied to a year "from" 25 March and, under a legal rule of interpretation dating back to at least 1628, this meant the tax year began a day later on 26 March.

For a fuller explanation about the origin of the United Kingdom income tax year see the article on the Calendar (New Style) Act 1750 under the heading Other effects: Why the United Kingdom income tax year begins on 6 April.

3.46. United States

3.46.1. Federal Government

The United States federal government's fiscal year is the 12-month period beginning 1 October and ending 30 September the following year. The identification of a fiscal year is the calendar year in which it ends; thus, the current fiscal year is 2022, often written as "FY2022" or "FY22", which began on 1 October 2021 and will end on 30 September 2022. By Wikideas1 - Own work https://www.cnsnews.com/news/article/terence-p-jeffrey/4155323000000-federal-spending-sets-record-through-augusthttps://fiscal.treasury.gov/files/reports-statements/mts/mts0921.pdfLiberationreport.com, CC0, https://commons.wikimedia.org/w/index.php?curid=82142934

Prior to 1976, the fiscal year began on 1 July and ended on 30 June. The Congressional Budget and Impoundment Control Act of 1974 made the change to allow Congress more time to arrive at a budget each year, and provided for what is known as the "transitional quarter" from 1 July 1976 to 30 September 1976. An earlier shift in the federal government's fiscal year was made in 1843, shifting the fiscal year from a calendar year to one starting on 1 July.^[62]

For example, the United States government fiscal year for 2022 is:

• 1st quarter: 1 October 2021 – 31 December 2021
• 2nd quarter: 1 January 2022 – 31 March 2022
• 3rd quarter: 1 April 2022 – 30 June 2022
• 4th quarter: 1 July 2022 – 30 September 2022

3.46.2. State Governments

State governments set their own fiscal year. Forty-six of the fifty states set their fiscal year to end on 30 June.^[63] Four states have fiscal years that end on a different date:

• Alabama, ends 30 September
• Michigan, ends 30 September
• New York, ends 31 March
• Texas , ends 31 August

The fiscal year for the Washington, D.C., government ends on 30 September.^[64]

Among the inhabited territories of the United States, most align with the federal fiscal year, ending on 30 September. These include American Samoa, Guam, the Northern Mariana Islands and the U.S. Virgin Islands.^[63] Puerto Rico is the exception, with its fiscal year ending on 30 June.

3.46.3. Businesses and Organizations

The tax year for a business is governed by the fiscal year it chooses. A business may choose any consistent fiscal year that it wants; however, for seasonal businesses such as farming and retail, a good account practice is to end the fiscal year shortly after the highest revenue time of year. Consequently, most large agriculture companies end their fiscal years after the harvest season, and most retailers end their fiscal years shortly after the Christmas shopping season.
