How to Calculate Earnings and Profits for Corporations

To calculate earnings and profits for a corporation, start with taxable income from Form 1120, Line 30, then add back income the corporation received tax-free, reverse deductions and carryovers that don’t reflect current-year cash outflows, subtract expenses that were paid but not deductible (federal income tax chief among them), and apply the timing adjustments the tax code requires for depreciation, expensing elections, installment sales, and long-term contracts. The resulting figure is current E&P, and it determines whether distributions to shareholders are taxable dividends, tax-free returns of capital, or capital gains.

Why the Calculation Matters

A “dividend” under federal tax law is any distribution made out of a corporation’s current or accumulated earnings and profits.¹ Section 301(c) then orders every distribution: dividend to the extent of E&P, return of capital against stock basis, then capital gain.² Without a current E&P figure and a running accumulated balance, no one can tell which tier applies. That is the whole reason the calculation exists.

Starting Point and Records You Need

The calculation begins with taxable income on Form 1120, Line 30.³ To make the required adjustments, pull together:

Financial statements and general ledger detail, which surface items that hit the books but not the return.
Schedule M-1 or, for corporations with total assets of $10 million or more, Schedule M-3.³
Tax-exempt income records: municipal bond statements, life insurance policy documents including cash surrender values and premiums paid.
Both regular tax depreciation schedules and Alternative Depreciation System (ADS) schedules.
Prior-year E&P workpapers, because accumulated E&P rolls forward from the corporation’s formation.

E&P is cumulative from inception, so older records stay relevant. The IRS advises keeping property-basis records until the statute of limitations expires for the year the property is disposed of.⁴ In practice, keep E&P workpapers for the life of the corporation.

Add Back Non-Taxable Income

Taxable income leaves out amounts the corporation actually received and could hand to shareholders. Those get added back.⁵ The common items:

Tax-exempt municipal bond interest.
Life insurance proceeds received on a policy where the corporation was the beneficiary.
For corporate-owned life insurance, the annual increase in the policy’s cash surrender value to the extent it exceeds the premium paid that year. That excess is economic income even though it never appears on the return.

Reverse Deductions That Don’t Reflect Current Cash Out

Some deductions reduce taxable income without any current-year outflow. Add them back.

Dividends Received Deduction

When one corporation receives dividends from another domestic corporation, a percentage is deductible to avoid multiple layers of corporate tax.⁶ For E&P, the full deduction is added back. The corporation still has the entire dividend in its account; the deduction is tax policy, not a cash reduction.

NOL and Charitable Contribution Carryovers

Net operating loss carryovers and charitable contribution carryovers used to reduce current taxable income are added back. They already reduced E&P in the year they arose, so letting them reduce E&P again would double-count. The calculation is meant to isolate what the corporation actually earned this year.

Subtract Non-Deductible Cash Outflows

The mirror of non-taxable income: expenses the corporation paid but couldn’t deduct. The cash is gone and can’t be distributed.

The largest item for most corporations is federal income tax. State and local taxes were deducted on Form 1120, but federal income taxes are never deductible for regular tax. For E&P, federal tax payments reduce the balance because they’re real outflows.⁵ Also subtract penalties and fines paid to government agencies, disallowed entertainment expenses, and any executive compensation above statutory deduction limits.

Timing Adjustments

This is where E&P diverges most sharply from the tax return, and where the biggest dollar swings usually sit.

Depreciation Under ADS

For tangible property, E&P depreciation must use the Alternative Depreciation System rather than the accelerated method used on the return.⁷ ADS generally applies straight-line over longer recovery periods. The difference between what was deducted on the return (MACRS or another accelerated method) and what ADS would allow gets added back to E&P. Total depreciation is the same over the asset’s life; only timing shifts.

Bonus Depreciation

The gap has widened. Under the One Big Beautiful Bill enacted in 2025, 100% bonus depreciation is permanent for qualifying property acquired after January 19, 2025.⁸ A corporation that expenses a $1 million asset entirely in year one for tax must still spread E&P depreciation straight-line over the ADS life. That produces a large year-one add-back and smaller subtractions in later years.

Section 179

Section 179 lets a corporation deduct the full cost of qualifying property in the year placed in service, up to $2,560,000 for 2026. For E&P, the Section 179 amount is spread ratably over five taxable years.⁹ A $500,000 Section 179 deduction reduces E&P by $100,000 in year one and $100,000 in each of the next four years.

Installment Sales

If the corporation used the installment method to recognize gain gradually as payments come in, E&P ignores the election. Compute E&P as if the full gain were recognized in the year of sale.¹⁰ Economic wealth increased at closing.

Long-Term Contracts

If the corporation uses the completed contract method for tax, E&P must use percentage-of-completion.¹¹ Income is recognized as work is performed rather than bunched at contract close.

Assembling Current E&P and Rolling to Accumulated E&P

The formula:

Taxable income (Form 1120, Line 30) + non-taxable income + reversed special deductions and carryovers − non-deductible expenses − federal income taxes paid ± depreciation and accounting method adjustments = Current E&P.

Current E&P is measured at the close of the taxable year and allocated pro rata across every distribution made during that year, regardless of whether a distribution went out in January or December.¹ Distributions exceeding current E&P then draw from accumulated E&P in reverse chronological order, most recent earnings first.

Whatever current E&P is not distributed at year-end rolls into accumulated E&P, a running total of undistributed earnings since formation. Current E&P is this year’s paycheck; accumulated E&P is the savings account.

When Accumulated E&P Is Negative

A corporation can have positive current E&P and a negative accumulated balance, for example after several loss years followed by a profitable one. Distributions are still dividends to the extent of positive current E&P. The negative accumulated balance does not offset the current year. Once current E&P is exhausted, there is no E&P left to support dividend treatment, and the remaining distribution falls into return of capital and capital gain.²

Redemptions and Liquidations

Ordinary distributions aren’t the only thing that moves the E&P balance. When a corporation buys back its own stock in a redemption treated as an exchange under Section 302(a), the reduction to E&P is limited to the ratable share of accumulated E&P attributable to the redeemed shares, not the full amount paid.¹² Redeem 10 of 100 outstanding shares, and only 10% of accumulated E&P is charged against the balance, regardless of the redemption price.

In a complete liquidation, shareholders treat the distribution as a stock exchange and the corporation’s E&P balance drops out of the shareholder-tax calculation. The exception is a parent-subsidiary liquidation: when an 80%-or-more-owned subsidiary liquidates into its parent, the parent inherits a proportionate share of the subsidiary’s accumulated E&P rather than recognizing gain.

Reporting When Distributions Exceed E&P

If distributions exceed E&P, meaning some or all of the payments are nondividend distributions, the corporation files Form 5452, Corporate Report of Nondividend Distributions.¹³ The form attaches to the corporation’s income tax return for the year of the nondividend distributions.¹⁴ Fiscal-year corporations attach it to the return for the first fiscal year ending after the calendar year of the distribution.

Form 5452 requires the E&P computation itself and a demonstration of how much of each distribution qualifies as a dividend versus a return of capital. The annual calculation cannot be skipped or estimated; the IRS expects the math when distributions exceed the balance. Even corporations that make no distributions benefit from maintaining the workpapers, because reconstructing years of E&P after the fact is expensive and error-prone.
