IDAPA 35.01.01.025 — TAXABLE YEAR AND ACCOUNTING PERIOD (RULE 025)

Section 63-3010, Idaho Code
01.
In General. A taxpayer will file his Idaho return for the same taxable year as filed for federal
income tax purposes. If a federal return is not filed, the taxable year will be the taxable year required by the Internal
Revenue Code, any other period that may be required by law, or the calendar year. Taxable year generally
corresponds to the taxpayer's annual accounting period unless a short-period return is required.
(4-6-23)
02.
Change of Accounting Period.
(4-6-23)
a.
If a taxpayer changes his accounting period for federal income tax purposes, he will make the same
change for the same period for Idaho income tax purposes. If prior approval of the Commissioner of the Internal
Revenue Service is required, a copy of that approval will accompany the Idaho short-period return.
(4-6-23)
b.
If a change does not require prior approval of the Commissioner of the Internal Revenue Service,
the change will be noted on the Idaho short-period return, along with a statement that no prior approval was required
and the authority cited.
