Schedule M1 and M3 Differences
Corporations and partnerships use Schedule M-1 and M-3 to reconcile financial (book) income with taxable income. Both Schedule M-1 and M-3 have similar filing goals, but they differ considerably in terms of detail, level of complexity, and filing prerequisites.
Purpose of Both Schedules
Every business must explain the differences in the financial statement income and the income in the tax returns. Differences may arise due to varying the revenue recognition, depreciation rules, or the existence of tax-exempt items. Both Schedule M-1 and M-3 serve the purpose of helping the IRS understand these differences.
Who Uses Schedule M-1?
Schedules M-1 is the simplified reconciliation form for C corporations filing Form 1120, S corporations filing Form 1120S, and partnerships filing Form 1065. Generally M-1 is used for businesses with total assets of less than $10 million at the end of the tax year. It offers a summary of book-tax differences.
Who is Required to File Schedule M-3?
Schedule M-3 is mandatory for:
- Partnerships and Corporations with total asset exceeding 10 million dollars.
- Large consolidated groups and partnerships.
For these larger entities, it replaces Schedule M-1 and offers a comprehensive reconciliation including a detailed, line-by-line summary. The IRS closely scrutinizes M-3 for sophisticated financial transactions and aggressive tax maneuvers.
