Question 1

What types of tax attributes can be carried forward?

Accepted Answer

Common carryforward tax attributes include Net Operating Losses (NOLs), tax credits (general business credits, foreign tax credits), capital losses (3 years for individuals, indefinite for corporations), and charitable contribution deductions exceeding AGI limits (5 years).

Question 2

How long can NOLs be carried forward?

Accepted Answer

Pre-2018 NOLs can be carried forward for 20 years. Post-2017 NOLs under TCJA have unlimited carryforward (no expiration). However, post-2017 NOLs are limited to offsetting only 80% of taxable income, while pre-2018 NOLs can offset 100%.

Question 3

What happens if a carryover expires unused?

Accepted Answer

If a carryover expires before being fully utilized, the remaining amount is lost permanently. The tax benefit is forfeited. This is why it's important to track carryovers and plan utilization, especially when approaching expiration.

Question 4

Do states have different carryover rules?

Accepted Answer

Yes, state tax carryover rules often differ from federal rules. Some states don't allow NOL carryforwards at all, some have shorter carryforward periods, and some have different credit carryforward rules. Always check state-specific rules when planning.
