What does the term '481 Adjustment' refer to?

The term '481 Adjustment' refers specifically to a change in taxable income that is necessary when there is a change in accounting methods.

Essentially, it allows for a one-time adjustment to prevent income from being double counted or overlooked during the transition from the old method to the new one.

When a taxpayer changes their accounting method, the IRS requires this adjustment to properly reflect the effects of the change on the taxpayer's income tax liability.
