Form 1065 (2023) Tax Year Compliance Checklist
2023 Form 1065 Distinctiveness
Form 1065 for 2023 reflects the Tax Cuts and Jobs Act rules for passthrough entities (Section 199A qualified business income deduction) combined with expanded Schedule K-1 disregarded entity reporting requirements. New separation of cash versus noncash contributions on Schedules K and K-1, redesigned liability reporting (Items K1, K2, K3), and updated commercial clean vehicle credit reporting under Section 45W distinguish the 2023 filing.
Year-Specific Programs Applicable to 2023 Form 1065
The qualified business income (QBI) deduction under Section 199A continues to flow through partnerships to partners for the 2023 tax year. Form 1065 now requires expanded Schedule K-1 reporting to identify disregarded entity partners separately, improving IRS matching and verification of partner-level compliance.
Ten-Step 2023 Compliance Checklist
Step 1: Gather Required Source Documents
Obtain Forms W-2 for guaranteed payments made to partners serving as employees, all Forms 1099 (interest, dividends, ordinary business income), Schedule K-1s from tiered partnerships or S corporations in which the partnership holds interest, and Form 1098 series if the partnership made mortgage interest or charitable contributions.
Step 2: Complete Schedule B for All 31 Questions
For 2023, answer all questions, including expanded question 10 (now includes 10d regarding FDAP income), question 29 (business interest expense and BEAT), and new question 30 (digital assets). Answers determine whether Schedules L, M-1, and M-2 are required.
Step 3: Determine Simplified Filing Eligibility
Check all four thresholds on Schedule B, line 4: (a) total receipts are less than $250,000, (b) total assets are less than $1,000,000 at year-end, (c) K-1s are filed and furnished timely, and (d) the partnership is not filing Schedule M-3. If all four are yes, the partnership is exempt from Schedules L, M-1, M-2, and certain K-1 items.
Step 4: Prepare Schedule B-1 If Ownership Threshold Exceeded
If any partner owns 50% or more of partnership capital, profits, or losses (including constructive ownership), complete Schedule B-1 listing partner name, address, TIN, entity type, and ownership percentage by vote and value for each.
Step 5: Complete Schedule K with 2023 Line Separations
Line 13a: cash contributions only.
Line 13b: noncash contributions only (new 2023 separation).
Line 12: Section 179 deductions.
Line 15: Include new energy credits, including the Section 45W commercial clean vehicle credit (vehicles placed in service but acquired before September 30, 2025).
Line 20: Activate code X if payment obligations are subject to guarantees.
Step 6: Report Clean Vehicle Credits per Section 45W
If a partnership placed qualified commercial vehicles in service during 2023, report credit on Schedule K, line 15. Attach Form 8936. Credit not available for cars acquired after September 30, 2025. The credit amount is the lesser of 30% of the basis (100% EV) or 15% of the basis (PHEV), compared to the maximum amounts by vehicle class.
Step 7: Prepare Schedule K-1 for Each Partner
Distribute one K-1 to each partner owning an interest during 2023. If a partnership interest is held through a disregarded entity, check the new item H2 box and enter the DE partner’s TIN and name. Report the taxpayer partner’s information in items E and F (not DE information). Item J expanded: separate boxes for sale vs. exchange of partnership interest.
Step 8: Complete Schedules K-2 and K-3 for International Items
If the partnership has controlled foreign corporations, foreign partners, or foreign source income, complete Schedule K-2 and provide partner-specific Schedule K-3. These schedules are required unless the partnership has no foreign activity or meets the de minimis foreign activity test.
Step 9: Attach All Required Schedules and Forms
Include with Form 1065 page 1: Schedule D (capital gains/losses), Schedule K-1 for each partner, Form 8825 (net rental real estate income if applicable), Form 4562 (depreciation), Form 1125-A (cost of goods sold), Form 8936 (clean vehicle credits), Schedule B-1 (if applicable), Schedule K-2 and K-3 (if applicable), Form 8996 (if qualified opportunity fund). Missing attachments noted on Schedule B question responses.
Step 10: Sign, Date, and File per IRS Instructions
Form 1065 must be signed by any authorized partner (per IRC Section 6063)—date return. Verify partnership name, EIN, tax year, all Schedule K-1 totals equal Schedule K columns, Schedule L totals equal Schedule M-2 capital accounts, and Schedule M-1 line 9 agrees with Analysis of Net Income (Loss) per Return, line 1—file per 2023 Where to File location for Form 1065.
Lines Added, Removed, Redesigned, or Updated for 2023
Schedule K-1, Item J (Disposition of Partnership Interest): Prior year instruction used a single checkbox for sale or exchange. Current 2023 instruction provides two separate boxes—one for sale, one for exchange—with differentiated guidance on when each applies. This represents a redesigned provision.
Schedule K, Line 13 (Contributions): Prior year instruction reported contributions on a single line. The current 2023 instruction is separated into Line 13a for cash contributions and Line 13b for noncash contributions, with all subsequent lines renumbered. Partnership must itemize the property contributed and its basis. This represents a split/redesigned provision.
Schedule K-1, Item K (Partner Liabilities): Prior year instruction used a single item K encompassing all liability categories. Current 2023 instruction is separated into K1 (liability breakdown), K2 (checkbox indicating whether lower-tier partnerships are included), and K3 (new: checkbox indicating whether liabilities are subject to guarantees or payment obligations). This represents a redesigned provision.
Schedule K, Line 15 and Box 15, Schedule K-1 (Other Credits): The prior year instruction used a generic “other credits” category. Current 2023 instruction expanded to explicitly include Section 45W commercial clean vehicle credits, qualified rehabilitation credits, and additional energy credit categories aligned with the 2023 law. This represents an updated provision.
Form-Specific Limitations for Partnership Form 1065
Limitation 1—Foreign Partnership Filing Requirement Exception: Foreign partnerships that have U.S. source income must file Form 1065 unless one of the following two exceptions applies: (1) no effectively connected income AND U.S. source income $20,000 or less AND less than 1% of items to direct U.S. partners AND not withholding foreign partnership, or (2) no effectively connected income AND no U.S. partners at any time AND not withholding foreign partnership. Exception (2) rarely applies.
Limitation 2—Centralized Partnership Audit Regime Election-Out Restriction: Only partnerships with 100 or fewer eligible partners may elect out of the centralized audit regime under Section 6221(b). Eligible partners include individuals, C corporations, foreign C-equivalent entities, S corporations, and estates of deceased partners only. Partnerships with trusts, disregarded entities, other foreign entities, or non-deceased estates cannot make an election, regardless of the number of partners. Election requires completion of Schedule B-2 and answering “yes” to Schedule B, question 31, attached to Form 1065.
