How does AMT paid on ISO exercise affect taxes on sale?

If a taxpayer exercises an ISO in 2001 and sells the shares in 2004, is the cost basis of the shares increased by any AMT paid in 2001?

Hello Dave,

No. The AMT might be partially recovered through the minimum tax credit. See Federal Form 8801 and the related instructions. The tax basis of the stock is adjusted for the additional income reported on the 2001 AMT schedule to prepare an AMT Schedule D, thus creating an AMT vs. regular tax difference to report at line 16 of Form 6251, so the regular tax will exceed the tentative minimum tax, permitting part of the minimum tax credit carryover to be used.

Good luck!
