§ 290.32 — Taxes for Part of Year, Computation

Plain-Language Summary

When a taxpayer files a return for less than a full year (such as when changing accounting periods), the tax is calculated by annualizing the income and then taking a proportional amount. Special rules apply for 52-53 week fiscal year changes resulting in very short periods.

Practical Notes
Relevant if you are changing your tax year (for example, from a calendar year to a fiscal year) – you must file a short-period return with the income annualized.
