# Form 56A - Instructions
Carryback or Carryover of Idaho NOL
For a corporation with multiple entities operating in Idaho, each entity with Idaho activity can carryback $100,000 of Net Operating Loss (NOL), up to the amount of Idaho taxable income per entity in the year carried back. Each member of a unitary group must complete a separate Form 56A to carryback and carryforward Idaho NOL.
For an affected business entity (ABE), the entity must carry forward an Idaho NOL to succeeding taxable years. If the entity doesn't make the election to be an ABE in any succeeding taxable year, the unused Idaho NOL will flow through to the members.
For losses commencing on or after January 1,
2013, you only have one year from the end of the loss year to file an amended return to carry back the
Application of an NOL (Example)
Idaho NOL and apply it to the prior two years. After that, you must carry the Idaho NOL forward. You can carry forward the remaining amount and apply it to the next 20 years until the NOL is fully absorbed.
For Idaho NOL incurred in any taxable year commencing on and after January 1, 2000 but before January 1, 2013, you must carry back the Idaho NOL and apply it to the prior two years. You can carry forward the remaining amount and apply it to the next 20 years until the NOL is fully absorbed.
You can carry back a maximum of $100,000 ($50,000 if you're filing as married filing separately) of Idaho NOL. You must carry forward any Idaho NOL in excess of $100,000.
In this example, 2025 is the loss year. The loss amount is ($249,000) (shown on line 7). The taxpayer has Idaho absorption income of $73,500 in 2023 and $44,900 in 2024 (shown on line 8). The taxpayer used $73,500 of the ($249,000) loss is used in 2023. The taxpayer can use only $26,500 of the loss in 2024 because the carryback is limited to $100,000. The taxpayer can use the remainder of the loss ($149,000) in the next 20 years.
