As a tax preparer, it is important to know how different business entities report and pay taxes. Partnerships can be especially complex. Their complexity comes from the fact that they generally do not pay income taxes at an entity level. Instead, they pass income, deductions, and credits through to their partners.
Even though partnerships do not typically pay income taxes directly, they must report their activity each year via Form 1065 and Schedule K-1s to the Internal Revenue Service (IRS). Form 1065 declares profits, losses, deductions, and credits. As you a tax preparer, you’ll typically prepare this form for your clients with domestic partnerships, foreign partnerships earning income in the United States, and nonprofit religious organizations.
What is the purpose of Form 1065?
Form 1065, US Return of Partnership Income, is an informational tax form filled out by partnerships to provide a financial performance and position statement, including profits, losses, deductions, and credits, to the IRS each tax year. A partnership doesn’t pay income taxes. Instead, any profit or loss is passed on to the partners using Schedule K-1, prepared for each partner using the information on Form 1065. The partners must report and pay taxes on their partnership income on their individual tax returns and pay income tax on their earnings. If you prepare Form 1065 for your clients, you must also prepare Schedule K-1 for each partner.
How partnerships are taxed as pass-through entities
Partnerships are considered pass-through entities, sometimes called flow-through entities, because they do not pay income tax at the entity level. Instead, the partnership’s taxable earnings move through the business and are reported by the individual partners on their own individual income tax returns.
In a pass-through structure, the partnership calculates its income, deductions, credits, and other tax items for the year. These amounts are then allocated to each partner based on the partnership agreement. The allocation is reported on Schedule K‑1, which shows each partner’s share of ordinary business income, rental income, guaranteed payments, credits, and other tax items.
Since the partnership itself does not pay income tax, the partners are responsible for reporting the amounts from Schedule K‑1 on their personal or corporate returns. This can create situations where a partner owes tax on income the partnership retained or reinvested.
Which clients should I file Form 1065 for?
Generally, you must file Form 1065 for any client whose business is classified as a partnership. The IRS defines a partnership as two or more people who carry a trade or business together and share profits, losses, and responsibilities. . Partnerships can take several legal forms, including:
- domestic partnerships
- general partnerships
- limited partnerships
- limited liability corporation (LLC)
- nonprofit religious organizations
- foreign partnerships
Domestic partnerships
All domestic business partnerships headquartered in the US must file Form 1065 annually. This requirement applies to any partnerships that have income, deductions, or credits to report. However, if a partnership does not receive income or incur expenses qualifying it to claim credits or deductions, it may not be required to file Form 1065.
Multi‑member limited liability companies (LLCs) also fall into this category. By default, a multi‑member LLC is taxed as a partnership unless it elects to be treated as a corporation by filing Form 8832 or Form 2553. If it remains under the default classification, it must file Form 1065.
Nonprofit religious organizations with a 501(d) classification also file as a partnership. They are responsible for showing that profits were given to their members as dividends.
Foreign partnerships
Foreign partnerships that have gross income connected to a U.S. trade or business generally must file Form 1065 and report how that income is allocated to partners.
A foreign partnership may not be required to file Form 1065 if it meets one of the following exceptions:
- No income effectively connected with a U.S. trade or business during the tax year
- U.S.-source income of $20,000 or less during the tax year
- Less than 1% of any partnership income, gain, loss, deduction, or credit is allocable to direct U.S. partners at any time during the tax year
- The partnership is not a withholding foreign partnership
What is included in the client’s Form 1065?
When preparing Form 1065, have your clients gather the following information and documents:
Business identification
- Employer Identification Number (EIN)
- Business start date
- Total number of partners
Partner information
- Partner names and contact details
- Partner Tax Identification Numbers (SSN or EIN)
- Each partner’s percentage of ownership and profit‑loss allocation
Financial information
- Year‑end financial statements
- Profit and loss statement showing revenue and net income
- List of deductible expenses
- Beginning‑of‑year and end‑of‑year balance sheets
TaxSlayer Pro will guide you through entering this information and ensure it is allocated correctly on Form 1065.
When and how to file a 1065 for your clients
Form 1065 is generally due March 15 for calendar‑year partnerships. This deadline represents the 15th day of the third month after the end of the partnership’s tax year. Fiscal‑year partnerships follow the same rule and must file by the 15th day of the third month after the close of their fiscal year.
If a partnership needs more time, it may request an extension by filing Form 7004, which grants an additional six‑month extension to submit Form 1065.
Partnerships may file electronically or by paper. However, the Internal Revenue Service (IRS) requires most partnerships that file 10 or more returns of any type during the tax year to e‑file Form 1065, with limited exceptions. Paper filing remains available for partnerships that do not meet electronic filing requirements or qualify for an exception.

Are there penalties for failing to file a 1065 on behalf of clients?
As a tax preparer, you are not personally penalized for a client’s late partnership return. However, the partnership can incur significant penalties if Form 1065 or partner Schedule K-1s are not filed and furnished on time.
If a partnership does not file Form 1065 by the deadline, it may face a late filing penalty. The penalty is typically $255 monthly (for a maximum of 12 months) not filed. This penalty is charged per partner who has not filed. You can request an extension for your clients who need more time to file to avoid this penalty.
If your partnership client fails to file and send Schedule K-1 to their partners by the deadline, they will also face a penalty. The IRS may impose a $340 penalty for each Schedule K-1 not filed. The maximum penalty is $3,783,000.
If your partnership client fails to file and receives a notice from the IRS, the partnership (or you as the tax preparer on their behalf) can send the IRS an explanation of why they were unable to file on time. The IRS can then determine if the reason for not filing a partnership tax return is sufficient and remove the penalty.
What’s the difference between Schedule K-1 and Form 1065?
Form 1065 reports the partnership’s annual results to the Internal Revenue Service (IRS), while Schedule K‑1 reports each partner’s share of those results to the partner.
Form 1065 is the first step in paying taxes on income earned by a partnership. Once you’ve prepared Form 1065 for your client, prepare Schedule K-1s for each partner.
Each Schedule K-1 identifies the partner’s allocated profits and losses for the tax year. This form is sent to the partners and used to prepare their personal income tax returns. These two tax forms work in tandem with each other to successfully report and help partners pay taxes on any income or loss experienced by the partnership.
