Schedule M‑3 (Form 1065) is required for partnerships with $10 million or more in total assets or $35 million or more in total receipts for the tax year. This schedule plays a critical role in reconciling net income (loss) reported on a financial statement with net income (loss) reported on Form 1065. It applies to complex partnerships subject to greater transparency requirements and provides the IRS with a clearer view of book-tax differences across multiple financial dimensions.The form is divided into three parts:
  1. Part I identifies the type of income statement used (e.g., GAAP, IFRS, tax basis), whether the statement is audited, and establishes a starting point for reconciliation.
  2. Part II lists income and loss reconciliation items — these include adjustments for items such as unrealized gains, intercompany transactions, and differences in income recognition.
  3. Part III details expense and deduction items that differ between book and tax accounting, such as depreciation, penalties, fines, and nondeductible expenses.
Each entry is categorized across four columns:
Net Income (Loss) Reconciliation for Certain Partnerships
The amount of the partnership’s total assets at the end of the tax year is equal to $10 million or more.
The amount of the partnership’s adjusted total assets for the tax year is equal to $10 million or more. If box B is checked, enter the amount of adjusted total assets for the tax year
The amount of total receipts for the tax year is equal to $35 million or more. If box C is checked, enter the total receipts for the tax year
An entity that is a reportable entity partner with respect to the partnership owns or is deemed to own an interest of 50 percent or more in the partnership’s capital, profit, or loss, on any day during the tax year of the partnership.

Schedule M‑3 is typically used in place of Schedule M‑1. However, if a partnership chooses to complete only Part I of Schedule M‑3 and meets the requirements, it may file Schedule M‑1 instead of Parts II and III. In such cases, the value reported on line 11 of Schedule M‑3 Part I must match line 1 of Schedule M‑1. Attach all supporting documentation where appropriate, particularly when reporting significant book-tax differences. Partnerships under common control or with foreign activities must also disclose additional detail.

Schedule M‑3 improves tax compliance by providing greater clarity on the timing and nature of income and expense reporting. Partnerships in sectors such as real estate, private equity, and professional services frequently use this schedule. If your partnership is filing consolidated returns, ensure each entity files a separate Schedule M‑3 unless otherwise directed. For lower-asset partnerships, refer to Schedule M‑1 (Form 1065) and Schedule M‑2 for simplified reporting. Use this tool to automate reconciliation and avoid common errors in column misalignment or omitted line entries.
