Schedule L on Form 1065 is the partnership’s balance sheet: assets, liabilities, and partners’ capital at the start and end of the tax year, reported at book value. Most partnerships have to complete it, but small partnerships that meet all four conditions on Schedule B, Question 4 can skip it. When it is required, the ending capital figure has to tie to the combined capital reported across every partner’s Schedule K-1, and that tie-out is what the IRS looks at first.
Which Partnerships Have to Complete Schedule L
Schedule L, together with Schedules M-1 and M-2, can be left blank only if the partnership answers “Yes” to all four parts of Schedule B, Question 4 on Form 1065:
- Total receipts for the year were less than $250,000. Receipts include gross receipts or sales, other income from page 1, and income items reported on Schedule K and Form 8825.
- Total assets at year-end were less than $1 million, measured at book value (the amount that would appear in Item F on page 1).
- Every partner’s Schedule K-1 is furnished by the return due date, including extensions.
- The partnership is not filing, and is not required to file, Schedule M-3.
All four have to be true. Miss any one and Schedule L is required for that year.1Internal Revenue Service. Instructions for Form 1065 Partnerships that qualify for the exception still answer the Schedule B questions to document that they qualify.
What Goes on the Balance Sheet
Schedule L uses four columns to show beginning-of-year and end-of-year balances, and everything is reported on the partnership’s book basis: historical cost adjusted for accumulated depreciation, amortization, and depletion recorded on the books. Those book figures often diverge from what the partnership claims for tax, which is exactly why Schedules M-1 and M-3 exist.
Assets
The asset section runs from current items (cash, receivables net of allowance for doubtful accounts, inventories, other current assets) through longer-term holdings (investments, loans to partners, depreciable and depletable property net of accumulated book depreciation, land, and intangibles). Book depreciation on the balance sheet follows the partnership’s financial accounting method, so it typically will not match the accelerated depreciation, Section 179, or bonus depreciation running through Form 4562. The total of all assets on line 14 matters beyond Schedule L itself: it is one of the figures the IRS uses to test whether the partnership crosses the $10 million threshold that forces Schedule M-3 in place of M-1.2Internal Revenue Service. Instructions for Schedule M-3 (Form 1065)
Liabilities
Liabilities are grouped by maturity. Accounts payable and other current liabilities (accrued interest, payroll taxes owed, deferred revenue) come first. Mortgages, notes, and bonds are then split: those due within one year go on one line, those payable in one year or more go on another. A catch-all line picks up anything else outstanding.
Partners’ Capital Accounts
Line 21, Partners’ Capital Accounts, is total assets minus total liabilities. This is the number that has to tie out. The ending balance on line 21 must equal the combined ending capital reported across every partner’s Schedule K-1, Item L. If the two figures do not agree, something in the return is wrong, and it will draw IRS attention. The line 21 balance reflects everything partners have put in, everything income and loss has added or taken away, and everything distributed back out.
Reconciling Book Income to Tax Income
Because financial accounting and the tax code treat many items differently, the return needs a formal bridge from one to the other. Schedule M-1 does that job for most partnerships. Schedule M-3 replaces it for larger ones.
Schedule M-1
Schedule M-1 starts with net income per the books and adjusts it to the taxable income figure on Schedule K. Adjustments go in two directions.
Items added back are usually book expenses the tax code will not let the partnership deduct in full. The classic example is business meals: only 50% is deductible, so the other half gets added back.3Office of the Law Revision Counsel. 26 USC 274 – Disallowance of Certain Entertainment, Etc., Expenses Fines, penalties paid to government agencies, and certain lobbying costs are added back in full. On the other side of the reconciliation, a partnership claiming Section 179 or bonus depreciation on Form 4562 will show a bigger tax deduction than its books recognize, and that extra deduction reduces book income when arriving at tax income.
Subtractions from book income are for items that are real income for accounting but not taxable, most commonly interest earned on municipal bonds.
When Schedule M-3 Applies Instead
A partnership must file Schedule M-3 rather than M-1 if it meets any one of these tests:
- Total assets of $10 million or more at year-end (Schedule L, line 14).
- Adjusted total assets of $10 million or more for the year.
- Total receipts of $35 million or more for the year.
- A reportable entity partner owns 50% or more of the partnership’s capital, profit, or loss and was itself required to file Schedule M-3 on its own most recent return.
Meeting any one triggers the requirement.2Internal Revenue Service. Instructions for Schedule M-3 (Form 1065) Schedule M-3 asks for far more detail than M-1, breaking every reconciling item into temporary differences (which reverse later) and permanent differences (which never do).4Internal Revenue Service.

Schedule M-2 and Tax-Basis Capital Accounts
Schedule M-2 is a roll-forward of combined partners’ capital. It shows how the equity balance on Schedule L, line 21, moved from the beginning of the year to the end. Beginning capital, plus contributions during the year, plus net income per M-1 or M-3, minus distributions, minus net losses, equals ending capital. That ending figure must match line 21 of Schedule L and the combined Item L totals from all Schedules K-1.
The Tax-Basis Reporting Requirement
Beginning with the 2020 tax year, partnerships must report each partner’s capital account on Schedule K-1, Item L, using the tax basis method.5Internal Revenue Service. Notice 2021-13 – Relief for Partnerships from Certain Penalties Related to the Reporting of Partners Beginning Capital Account Balances That means using the transactional approach: every contribution, allocation, and distribution is recorded as it happens.6Internal Revenue Service. Partners Instructions for Schedule K-1 (Form 1065)
Tax-basis capital drives two calculations the partner cares about most: the gain or loss they recognize on selling their interest or on a liquidating distribution, and the loss limitation that caps how much partnership loss they can deduct on their own return. A partner’s Item L capital may not equal their full adjusted tax basis in the partnership interest, because basis also includes the partner’s share of partnership liabilities.
Negative Capital Accounts
A partner’s tax-basis capital can go negative when distributions and allocated losses over time exceed contributions and allocated income. This is common in leveraged partnerships, particularly real estate. The partnership reports the negative figure on the K-1 anyway. A negative Item L generally means the partner has taken more value out than they have put in, and additional distributions can trigger taxable gain.
Correcting a Schedule L That Was Filed Wrong
If errors turn up on a previously filed Schedule L, the fix is an amended return. Partnerships filing electronically use an amended Form 1065; paper filers use Form 1065-X.7Internal Revenue Service. Instructions for Form 1065-X
One boundary worth flagging: partnerships subject to the centralized audit regime under the Bipartisan Budget Act (BBA partnerships) generally cannot file a traditional amended return. They correct partnership-related items through an Administrative Adjustment Request (AAR) instead. Non-BBA partnerships can go either way.
An amendment attaches the corrected Schedule L and supporting schedules and explains each change with the computations behind the new figures. If the corrections shift any partner’s share of income, loss, or capital, the partnership issues corrected Schedules K-1 to those partners.
Deadlines and Penalties
Form 1065 is due on the 15th day of the third month after the tax year ends. For calendar-year partnerships that is March 15. Filing Form 7004 gets an automatic six-month extension to September 15.8Internal Revenue Service. Publication 509 (2026), Tax Calendars
Late filing is expensive. Under Section 6698, the IRS charges a penalty for each month (or partial month) the return is late, up to 12 months, calculated as a base amount of $195 (adjusted annually for inflation) times the number of partners during any part of the year.9Office of the Law Revision Counsel. 26 USC 6698 – Failure To File Partnership Return The IRS can waive it for reasonable cause; forgetfulness does not qualify.
Inaccurate balance sheet figures create a different exposure. If misstatements on Schedule L feed into underpayments on any partner’s personal return, the IRS can assess an accuracy-related penalty of 20% of the underpaid tax attributable to negligence or a substantial understatement of income.10Internal Revenue Service. Accuracy-Related Penalty That is the practical reason the K-1 tie-out to line 21 matters: a balance sheet that does not reconcile is a balance sheet the IRS will question.
