IRS Publication 5035 – In the world of tax statistics, IRS Publication 5035 stands out as a vital resource for understanding the intricacies of partnership tax returns. Released by the Internal Revenue Service’s Statistics of Income (SOI) Division, this publication offers detailed estimates on line items from U.S. partnership returns for Tax Year 2023. Whether you’re a tax professional, researcher, or business owner, this guide breaks down what Publication 5035 entails, its purpose, methodology, and key insights to help optimize your understanding of partnership taxation.
What Is IRS Publication 5035?
IRS Publication 5035, titled “Partnership Returns Line Item Estimates,” provides estimated frequencies and dollar amounts for entries on various forms and schedules associated with Form 1065, the U.S. Return of Partnership Income. First introduced for Tax Year 2010, it compiles data from a sample of partnership returns processed by the IRS, offering a snapshot of how partnerships report income, deductions, credits, and other items. The 2023 edition, revised in December 2025, focuses on returns filed during Calendar Year 2024 and is available as a free PDF download from the IRS website.
This publication is part of the broader SOI Tax Stats series, which aids in tax policy analysis, compliance monitoring, and economic research. It complements other IRS resources like the SOI Bulletin, which includes articles on partnership trends for specific tax years.
Purpose of Publication 5035
The primary goal of Publication 5035 is to present estimates of taxpayer entries on partnership forms, including frequency counts (how many returns report a specific line) and population estimates of dollar amounts (where applicable). It helps stakeholders analyze trends in partnership filings, such as income sources, deduction patterns, and credit utilization. For instance, it supports identifying common reporting practices in sectors like real estate or finance, which dominate partnership activity.
Unlike actual tax return counts, these are statistical estimates derived from samples, making them useful for high-level insights rather than precise audits. The data also informs projections for future tax years and assists in understanding economic shifts, such as changes in business structures or investment behaviors.
Methodology Behind the Estimates
Publication 5035 relies on a stratified probability sample of partnership returns processed by the IRS. This sampling approach ensures representation across different partnership sizes, industries, and filing types. Estimates include:
- Frequency Counts: Rounded to whole numbers, indicating how often a line item is used.
- Dollar Amounts: Rounded to the nearest $1,000 (with $500 or more rounded up), shown in thousands.
- Sampling Variability Measures: Coefficients of variation (CV) and 95% confidence intervals for key totals to assess estimate reliability.
- Caveats: Items based on fewer than 10 returns are marked as unreliable (*), and some data is deleted [d] to protect confidentiality. Certain forms may be excluded if sample sizes are insufficient.
For Tax Year 2023, the methodology mirrors previous years, focusing on forms like Form 1065, Schedules K, L, M-1, M-2, M-3, and attachments such as Form 4562 (Depreciation) and Form 8825 (Rental Real Estate). Electronic filings dominate, representing about 98.1% of partners, 98.0% of total assets, and 98.0% of total income minus deductions in 2023.
Key Forms and Sections Covered in Publication 5035
The publication breaks down line item estimates across core partnership forms and schedules. Based on the structure from recent editions, it includes:
- Form 1065: Covers gross receipts, cost of goods sold, ordinary business income/loss, deductions (e.g., salaries, depreciation, interest), and taxes.
- Schedule K (Partners’ Distributive Share Items): Details income types (e.g., rental income, capital gains), deductions, credits, and international items.

Key Insights and Statistics from 2023 Partnership Returns
While Publication 5035 offers detailed line-by-line estimates, broader SOI data reveals significant trends for Tax Year 2023:
- Number of Returns and Partners: Partnerships filed approximately 4.5 million returns, a slight increase from prior years. The number of partners grew 5.0% to 30,239,463 from 28,797,574 in 2022, reflecting ongoing growth in pass-through entities. Partnerships with fewer than three partners comprised a substantial portion of filings.
- Sector Breakdown: The real estate, rental, and leasing sector accounted for about half of all partnerships (49.6%-50.7%) and a third of partners (32.3%-33.9%). Finance and insurance led in total assets (58.8%) and pass-through income (54.2%).
- Assets and Receipts: Total assets reached new highs, building on the 3.3% increase to $52.5 trillion in 2022. Receipts totaled around $12.5 trillion or more, up from previous years.
- Income and Deductions: Pass-through income (total income minus deductions) was substantial, with partnerships allocating significant amounts to partners. For context, 2022 saw $2.6 trillion in pass-through income, a 34.3% decrease from 2021, but 2023 showed recovery with increased partner counts. Key items include ordinary business income, rental real estate income/loss, and interest income.
- Notable Changes: Electronic filing continued to rise, covering nearly all major metrics. Partnerships classified as other partnerships received the largest income allocations. Limited liability companies (LLCs) dominated, making up over 72% of returns for recent years.
These estimates highlight the growing role of partnerships in the U.S. economy, particularly in real estate and finance.
