Is the AAA the same as the corporation's retained earnings?

Conceptually similar but mechanically distinct. Retained earnings is a GAAP balance-sheet account; the AAA is a tax-specific notional account. The two often differ because of book-tax differences (timing of depreciation, non-deductible expenses, etc.). The AAA matters for tax purposes; retained earnings matters for financial-statement purposes.

What happens to the AAA when an S corp terminates?

The AAA balance becomes irrelevant for future distributions because the S election is gone. If the corporation converts to a C corp, future distributions are taxed as C corp dividends. If the corporation liquidates, the AAA helps establish the basis recovery and capital-gain treatment for shareholders.

Can multiple shareholders have different AAA balances?

No. The AAA is a corporate-level account, not per-shareholder. Each shareholder's individual stock basis is separate. The AAA tells you what's available for tax-free distribution; basis tells you whether a particular shareholder can receive that distribution tax-free.

How does the AAA differ from the Canadian CDA?

Different purposes. The CDA holds tax-free dividends arising from specific items (capital gains, life insurance proceeds). The AAA holds taxable income that has already been passed through to S corp shareholders and can be distributed tax-free (because it's already been taxed). The mechanics are different but both serve to prevent double taxation.

Compliance & tax

Accumulated Adjustment Account (AAA)

S corp notional tax account tracking pass-through earnings available for tax-free distribution to shareholders.

Definition

The Accumulated Adjustment Account (AAA) is a notional tax account maintained by S corporations under IRC § 1368(e)(1). It tracks the corporation's accumulated taxable income (less prior distributions) since electing S status. Distributions from a S corp first reduce the AAA balance and are tax-free to shareholders up to their stock basis. AAA tracking is critical for S corps that were previously C corps, where the distribution may instead come out of accumulated earnings and profits (E&P) and be taxed as a dividend.

How the AAA works

The AAA is a running balance tracking the S corp's cumulative taxable income since electing S status:

Increases AAA: ordinary taxable income, separately stated income items, tax-exempt income (in some cases), gains
Decreases AAA: ordinary losses, separately stated loss items, non-deductible expenses (in some cases)
Distributions: tax-free up to the AAA balance. Excess distributions are first taxed as dividend (from accumulated E&P, if any), then as capital gain (return of basis), then as ordinary income

Distribution ordering under § 1368(c)

For an S corp with prior C corp history, distributions are taxed in this order:

1. From AAA: tax-free to shareholders, up to their stock basis
2. From accumulated E&P: taxed as a dividend (from the C corp years)
3. From other adjustments account (OAA): tax-free distributions of items like tax-exempt income
4. From shareholder basis: return of capital, tax-free up to basis
5. Capital gain: any excess is treated as gain from sale of stock

AAA and S corp without prior C corp history

If an S corp never had C corp earnings (e.g., elected S from inception), the AAA tracking is straightforward and distributions are simply tax-free up to shareholder basis. The AAA matters most when:

The S corp was previously a C corp (with E&P that pre-dates the S election)
Shareholders have varying tax basis (the AAA establishes the corporate-level pool)
Multiple shareholders are paid different amounts (allocation rules apply)
Conversion or termination is contemplated (final AAA balance is relevant)
