K-1 income for investors

The Schedule K-1 is a tax form that reports pass-through income from partnerships, S-corporations, and other pass-through entities to individual investors. As an investor, you receive a K-1 showing your share of the entity’s income, deductions, capital gains, and credits. You must report this K-1 income on your personal return and pay tax at your individual rate, even if the entity did not distribute cash. K-1 income is one of the most complex areas of tax filing.

How K-1 works: partnership example

You invest $100,000 in a real estate partnership. The partnership earns $500,000 in rental income and takes $200,000 in expenses (including depreciation). Net taxable income is $300,000.

If you own 25% of the partnership, your K-1 shows:

• Your share of income: $75,000
• Your share of depreciation deduction: $50,000 (if 25% of total)
• Your share of net income: $25,000

You report $25,000 on your personal return and pay tax at your marginal rate. If you are in the 32% bracket, you owe $8,000 in federal tax on K-1 income—even if the partnership did not distribute any cash to you.

This is different from dividends, where you pay tax only on amounts actually distributed.

Income vs. distributions

K-1 income and distributions are separate. You pay tax on K-1 income even if you receive no distribution. Conversely, if you receive a large distribution, it is not additional taxable income (unless it exceeds your cost basis, in which case it is a return of capital).

Example: K-1 shows $25,000 income, but the partnership distributes nothing to you. You owe tax on $25,000. The next year, the partnership distributes $50,000 cash to you. This distribution is not taxable (it is a return of your accumulated equity).

The complexity: multiple items

A K-1 does not just report net income. It breaks down the income and deductions into categories:

• Ordinary business income (or loss)
• Rental real estate income (or loss)
• Guaranteed payments (if you are a working partner)
• Capital gains (may be long-term or short-term)
• Depreciation deductions (which trigger recapture)
• Charitable contribution deductions
• Tax credits (foreign tax credits, etc.)

Each category is reported separately and has different tax treatment. You must track these across multiple lines on your return.

Timing issue: the K-1 delay

The partnership or S-corp must file its return and issue K-1s by March 15 (or later if an extension is filed). You then have until April 15 to file your personal return. In reality, K-1s often arrive late (April or May), making it hard to file on time. You can file with an estimate if the K-1 is late and amend later.

Self-employment tax

Some K-1 income is subject to self-employment tax (15.3% for Social Security and Medicare). Passive K-1 income (from rental real estate, for instance) is generally not self-employment taxable. Active business income or guaranteed payments usually are.

Rules are complex; consult a tax professional.

Losses and limitations

If the partnership has a loss, you receive a K-1 showing a loss that you can deduct. However, passive loss limitations apply: you can deduct losses only to the extent of passive income you received that year (or $25,000 if you actively participate in rental real estate). Excess losses are carried forward.

Active business losses may be deductible without limitation, but you must prove active participation.

Depreciation recapture and K-1

If the partnership owns real estate or equipment, depreciation deductions flow through on the K-1. You reduce your cost basis by those deductions. When the partnership eventually sells the property, depreciation recapture also flows through on K-1, and you pay tax on the recapture portion.

This is one of the most common sources of K-1 complexity for real estate investors.

Alternative Minimum Tax

Large K-1 income and certain deductions (like depreciation) can trigger alternative minimum tax (AMT) for high-income investors. This is an additional tax calculation required for some individuals.
