Interactive Guide to Form 1065
The Basics of Partnership Taxation
A partnership tax return is an informational filing; the partnership itself doesn't pay tax. Instead, it passes income and deduction items to its partners. Understanding this "pass-through" principle is the start of every strategy.

Ordinary Business Income
This is the net profit or loss from the partnership's core business activities. It's calculated by subtracting ordinary business expenses from gross receipts and is reported in Box 1 of Schedule K-1, directly affecting a partner's taxable income.
Separately Stated Items
These are items subject to special tax rules, like capital gains, interest income, and charitable contributions. They retain their unique character and are passed through to partners to be treated differently based on each partner's individual tax situation. This is where tax planning happens.

Correctly classifying income and strategically using deductions can significantly reduce a partner's tax burden. See the effects for yourself with the scenarios below.
Capital Gains vs. Ordinary Income: Tax Impact Analysis
The same amount of profit can result in a lower tax bill if it qualifies as a long-term capital gain, which is taxed at a lower rate. Use the slider to see the tax difference at various profit levels.
Estimated Tax Savings from Proper Classification:
Using the Section 179 Deduction
This powerful benefit allows for the immediate deduction of asset purchase costs. However, it's limited by the partner's total business income.
Charitable Contribution Deductions
A partnership's donations are passed through to partners for deduction on their personal returns. The savings depend on the partner's tax rate.
Strategic Insights & Case Studies
Tax filing isn't just an annual chore. It's a strategic activity that should align with business operations, entity structure, and long-term planning to create value. Explore the cases below for ideas.
Depreciation and passive activity losses from real estate can offset a partner's other passive income, reducing taxes. This becomes a very powerful strategy if a partner qualifies as a "real estate professional," as loss deduction limits are removed. This is a crucial factor to consider when structuring the partnership.
Early-stage tech startups should aggressively pursue the Research & Development (R&D) tax credit. This credit passes through to partners, providing a direct, dollar-for-dollar tax reduction. Furthermore, it's vital to accurately track each partner's basis (their investment in the partnership) from day one. This is fundamental for calculating capital gains when the company is eventually sold.
"Guaranteed payments" can be used to provide a stable income to family members active in the business, regardless of the partnership's profitability. Conversely, charitable contribution deductions can be strategically allocated to family members in higher tax brackets to optimize the family's overall tax burden. This flexibility can be defined in the partnership agreement.
