Section 382 limitation

The section 382 limitation caps annual use of a corporation's pre-change losses after an ownership change of more than 50 percentage points over three years, at the company's value times a long-term tax-exempt rate.

Definition

Section 382 limits the taxable income a loss corporation may offset with pre-change losses after an ownership change. An ownership change occurs when, after an owner shift or equity structure shift, the ownership of 5-percent shareholders has increased by more than 50 percentage points over the lowest percentage held during the testing period, generally three years. The annual limit is the value of the old loss corporation's stock immediately before the change times the long-term tax-exempt rate. Unused limit carries to the next year. If the business is not continued for two years after the change, the limit is zero.

Why it matters in an audit or review

Financing rounds, buyouts and share transfers can trigger an ownership change that strands part of a deferred tax asset. Auditors ask for the ownership study, evaluate whether the asset is still realizable, and consider the valuation allowance.

Example

Illustrative: a loss corporation is worth $4,000,000 before a change and the applicable rate is 3%. The annual limit is $4,000,000 x 3% = $120,000. Against $1,500,000 of pre-change NOLs, full use would take $1,500,000 / $120,000 = 12.5 years, apart from other planning.

Common mistakes

  • Missing small, cumulative transfers that add up inside the testing period.
  • Not updating the study after a new funding round.

  • Valuation allowance
    A valuation allowance reduces a deferred tax asset to the amount more likely than not to be realized, based on positive and negative evidence about future taxable income.
  • Deferred tax assets and liabilities
    Deferred tax assets and liabilities capture the future tax effects of temporary differences between book and tax bases, measured at enacted tax rates under ASC 740 and classified as noncurrent.
