Still unclear whether you are asking about IRS form 7203 S Corporation Shareholder Stock and Debt Basis Limitations. Please clarify.
The instructions do not make any reference to a separate AMT calculation.
Form 7203 is filed by S corporation shareholders who:
- Are claiming a deduction for their share of an aggregate loss from an S corporation (including an aggregate loss not allowed last year because of basis limitations),
- Received a non-dividend distribution from an S corporation,
- Disposed of stock in an S corporation (whether or not gain is recognized), or
- Received a loan repayment from an S corporation.
