Understanding Schedule M-2 on IRS Forms 1120 and 1120-S is being brought to you from the rear passenger seat of my Toyota Sienna while commuting back to Fort Collins, Colorado, where my eldest is navigating CSU’s new Agricultural Biology program.

To assuage pending separation anxiety, jotting notes on Schedule M-2 seemed better than barraging the lad with copious and purportedly repeated questions. After all, the M-2 is getting more attention these days as one of the places where non-taxable income is reported, which, incidentally, has arrived in droves due to the plethora of PPP loan forgiveness programs available to small business owners.

For the following 6000 words or so, this post addresses accounting for income taxes and Schedule M-2 of Form 1120-S for S-Corp shareholders, including LLC members electing to be treated as S-corporations, including:

Learning about temporary and permanent differences between book and taxable income is challenging but not necessarily daunting. It most certainly separates the tax pros from transactional tax form processors and makes those of us armed with this knowledge a hit at the #nerdfests.

The Internal Revenue Code determines taxable income, whereas book income is determined by applying generally accepted accounting principles (GAAP). This causes differences, sometimes significant, between taxable income for IRS (& state) purposes and book income (aka pretax financial income for shareholder purposes) due to MANY underlying differences in the rules for determining these amounts.

The big one I see a lot of is using different accounting methods for book and tax purposes. Whereas a cash-basis taxpayer recognizes expenses on the tax return when paid, an accrual-basis taxpayer deducts expenses when incurred. There can be a big difference in income for reporting purposes based on when an expenditure is recognized as a deductible expense for income tax purposes.

In addition to reconciling financial net income to taxable income on Schedule M-1, the corporation is often required to complete Schedule M-2, Analysis of Unappropriated Retained Earnings per Books. Schedule M-2 reconciles the corporation’s unappropriated retained earnings account as found on the beginning-of-the-year and end-of-the-year balance sheets, both of which are listed on Schedule L. An analysis of unappropriated retained earnings may be presented as a statement of retained earnings for financial reporting purposes.

Reconciling Beginning and Ending Unappropriated Retained Earnings

To analyze the changes in unappropriated retained earnings during the year, the following items are added to the beginning of the year balance of unappropriated retained earnings:

To reconcile the beginning unappropriated retained earnings balance to the ending balance, the following items are subtracted:

Other Increases in Unappropriated Retained Earnings

The following are examples of items other than net income that are added to the beginning unappropriated retained earnings balance on Schedule M-2:

Prior-Period Adjustments

Prior-period adjustments are included in the items that affect retained earnings (unappropriated) per books, are primarily corrections of errors in the financial statements of prior periods, and may either increase or decrease retained earnings in the year of the adjustment. They are reported as direct adjustments of the beginning balance of retained earnings and are shown net of tax effect.

Tax Deductible Expenses

Two conditions must be met for tax purposes before an expense can be deducted.
