An individual taxpayer owns 100% of the stock of an S corporation. At the beginning of the current tax year, the shareholder's adjusted basis in the corporation's stock was $75,000. During the year, the S corporation reported the following operational and investment items:
• Ordinary business loss: $15,000
• Municipal bond interest income: $8,000
• Long-term capital gain: $5,000
• Short-term capital loss: $12,000
What is the shareholder's total adjusted stock basis at the end of the tax year?
❓ WHY OPTIONS ARE CORRECT/INCORRECT:
✅ Option 4 (Correct): An S corporation shareholder adjusts their stock basis annually by adding all income items (including tax-exempt income like municipal interest) and subtracting all loss and deduction items passed through. The basis cannot be reduced below zero. Basis is increased first by the $8,000 municipal interest and the $5,000 long-term capital gain, bringing it to $88,000. It is then reduced by the $15,000 ordinary business loss and the $12,000 short-term capital loss, resulting in a year-end basis of $61,000.
❌ Option 1 (Incorrect): This option incorrectly omits the $8,000 municipal interest income from the basis calculations. Tax-exempt income must increase basis to ensure that the distribution of those funds remains tax-free to the shareholder in the future.
❌ Option 2 (Incorrect): This option miscalculates the adjustment by treating the short-term capital loss as non-deductible or omitting it entirely, which leaves the ending basis artificially high.
❌ Option 3 (Incorrect): This choice represents a computational error where ordinary and capital items are blended incorrectly, or where tax-exempt interest is treated as a deduction instead of an upward adjustment.
📊 SUMMARY CALCULATIONS:
- Beginning Stock Basis: $75,000
- Add: Municipal Interest Income (Tax-Exempt): +$8,000
- Add: Long-Term Capital Gain: +$5,000
- Less: Ordinary Business Loss: -$15,000
- Less: Short-Term Capital Loss: -$12,000
- Year-End Adjusted Basis: $75,000 + $8,000 + $5,000 - $15,000 - $12,000 = $61,000
