Tax Forms a Syndication Investor Receives and Files Each Year
On this page
A syndication investor usually receives one core tax document each year: the Schedule K-1 (Form 1065) from the deal company, sometimes with state K-1s. Distributions are not on a 1099. You use the K-1 to complete your own return, and depending on your numbers you may also file forms for passive loss limits, at-risk limits and, in a sale year, the sale.
If you are the sponsor, we built DoorRaise to deliver K-1s to investors once the deal's accountant prepares them. This guide is for investors who want to know what to expect. See also our K-1 explainer.
What forms come from the syndication?
| Form | What it is | When |
|---|---|---|
| Schedule K-1 (Form 1065) | Your share of the company's income, deductions, credits and distributions | After the company files, often March to September |
| State K-1 or composite statement | Your share of state-sourced income, if the property state requires one | With or after the federal K-1 |
| Annual or quarterly report | Operating results, not a tax form | Throughout the year |
| Distribution statement | Cash paid to you | Each distribution |
The deal company files Form 1065 by March 15 for a calendar year, or by September 15 with an extension. K-1s often follow the company's return. See why K-1s run late.
What forms might I file on my own return?
| Form | Why you might need it |
|---|---|
| Form 1040 with Schedule E, Part II | Reports income or loss from a partnership |
| Form 8582 | Limits passive losses. See passive loss carryovers |
| Form 6198 | Limits losses to the amount you have at risk. See at-risk rules |
| Form 8960 | Net investment income tax for higher incomes. See NIIT |
| Form 4797 | Sale of business or rental property, including recapture and Section 1231 gain |
| Schedule D and Form 8949 | Capital gain if you sell your interest or the property is treated that way |
| Form 8995 or 8995-A | The qualified business income deduction, when the K-1 reports it. See Section 199A |
| Nonresident state return | Required in some states where the property sits. See state returns |
| Form 990-T | Filed by an IRA that owns the interest and has UBTI. See self-directed IRAs |
Whether you need each form depends on your income, basis and other passive activity. A CPA decides.
How do distributions show up?
Cash you receive appears on the K-1 as a distribution, in Box 19 on the federal form, and in the capital account section. It is generally not taxed as income when received, but it reduces your basis, and a distribution above basis can create gain. See Box 19 explained and return of capital.
You can have taxable income without receiving cash. Your share of income is taxed as it is earned by the company, whether or not it is distributed. See phantom income.
A rough yearly calendar
| When | What happens |
|---|---|
| January | Gather year-end distribution totals and keep records |
| By March 15 | Deal company's return is due, or an extension is filed |
| March to September | K-1s arrive, often late in this window |
| April | Personal return due, or file an extension |
| Quarterly | Estimated tax payments if you owe. See estimated taxes |
| October | Extended personal return due |
Many investors file an extension and send the return after the K-1 arrives. Interest on any tax owed runs from April regardless.
How to stay ready
- Keep every distribution statement and the capital account statements. See capital account statements.
- Ask the sponsor when K-1s will be ready and which accountant prepares them.
- Tell your CPA about the investment at the start of the year, not in March.
- Check whether the property state requires a nonresident return.
- Decide whether to pay estimated tax if the K-1 will show income.
- Keep your basis worksheet. See outside basis vs capital account.
Frequently asked questions
Will I get a 1099 from the syndication?
Usually not for distributions. The company reports through the K-1. Some payments, such as guaranteed payments, still go through the K-1. Occasionally a 1099 may be issued for other items, so read the K-1 package.
What if my K-1 is late?
File an extension and wait for the K-1 rather than guessing the numbers. If you file without it and must amend, that adds work.
Do I report distributions as income?
Not simply. You report your share of income or loss from the K-1. The cash distributions reduce basis.
Do I need a CPA?
Many investors use one, because passive loss, basis and state rules are involved.
Does the sponsor give tax advice?
No. The sponsor delivers the K-1. Your CPA advises on your return.
