S-Corp Accumulated Adjustments Account (AAA) Explained

AAA basics:

What AAA is:

• A corporate-level running total (not per-shareholder)
• Tracks cumulative S-Corp income minus distributions since the S election date
• Reported on Form 1120-S, Schedule M-2

AAA increases for:

• Ordinary business income
• Separately stated income items (capital gains, interest, etc.)
• Does NOT increase for tax-exempt income (that goes to the Other Adjustments Account, OAA)

AAA decreases for:

• Distributions to shareholders (but not below zero for distribution purposes)
• Ordinary business deductions and losses
• Separately stated deduction items
• Non-deductible expenses related to tax-exempt income: NO (those reduce OAA)
• Non-deductible expenses NOT related to tax-exempt income: YES (reduces AAA)

AAA can go negative (from losses exceeding prior income), but distributions cannot reduce AAA below zero. A negative AAA means losses have exceeded the S-Corp’s accumulated income (distributions alone can’t push it below zero). While AAA is zero or negative, distributions come from E&P (if any) and then from remaining stock basis.

Distribution ordering rules (when E&P exists):

Source	Tax Treatment
1. AAA	Tax-free (to the extent of shareholder stock basis)
2. E&P (if any from C-Corp years)	Taxed as qualified dividends
3. Remaining stock basis	Tax-free return of capital
4. Excess over basis	Capital gain

If no E&P exists (always been an S-Corp): All distributions are tax-free to the extent of stock basis, then capital gains. AAA is still tracked but the E&P layer doesn’t apply.

Election to bypass AAA: The S-Corp can elect under IRC 1368(e)(3) to treat distributions as coming from E&P first (bypassing AAA). This is useful when the corporation WANTS distributions taxed as qualified dividends (for example, to clear out C-Corp E&P so the corporation isn’t exposed to the passive investment income tax, or to losing its S status after three years of E&P plus passive income over 25% of gross receipts).
