What is the deadline for partnership tax returns?

Partnership tax returns (Form 1065) are due March 16, 2026 for calendar-year partnerships. Partnerships can request an automatic 6-month extension using Form 7004, extending the deadline to September 15, 2026. Extensions grant more time to file but don’t extend the time to pay any tax owed by partners.

Do partnerships pay federal income tax?

No, partnerships do not pay federal income tax. Partnerships are pass-through entities that report income, deductions, gains, and losses on Form 1065, but the partnership itself doesn’t pay tax. Instead, income and deductions pass through to partners via Schedule K-1, and partners report their share on individual or corporate tax returns.

How are partnership distributions taxed?

Partnership distributions are generally not taxable if they don’t exceed the partner’s tax basis in the partnership. Distributions become taxable gain only when they exceed basis. This differs from guaranteed payments, which are always taxable to the receiving partner and deductible by the partnership.

What is Form 1065 used for?

Form 1065 (U.S. Return of Partnership Income) is an information return that partnerships file annually to report the partnership’s income, deductions, gains, losses, and other tax items. The form calculates each partner’s distributive share of income and generates Schedule K-1s showing each partner’s allocated amounts.

What is a K-1 form?

Schedule K-1 (Form 1065) reports each partner’s share of partnership income, deductions, credits, and other tax items. Partners receive K-1s annually and use them to report partnership activity on their individual or corporate tax returns. K-1s show the partner’s distributive share regardless of whether distributions were actually made.

What are guaranteed payments?

Guaranteed payments are payments to partners for services or use of capital that are determined without regard to partnership income. Unlike profit distributions, guaranteed payments are deductible by the partnership and taxable to the receiving partner, similar to W-2 wages. They’re subject to self-employment tax for active partners.

How is partner basis calculated?

Partner basis starts with the partner’s initial capital contribution plus any additional contributions. Basis increases with the partner’s share of partnership income and decreases with distributions and the partner’s share of losses. Basis determines whether distributions are taxable and whether the partner can deduct losses.

How much does partnership tax preparation cost?

Partnership tax preparation costs typically range from $1,800 to $4,500 depending on complexity. Factors include number of partners, number of states, special allocations, and whether prior returns need correction. At SDO CPA, we provide upfront estimates after reviewing your partnership structure.

Do I need a CPA for my partnership?

While partnerships can file Form 1065 themselves, partnership taxation is complex. Issues like basis tracking, substantial economic effect allocations, multi-state compliance, and Section 754 elections require specialized expertise. A CPA specializing in partnerships prevents costly mistakes and identifies tax-saving opportunities.

Can I convert my partnership to an S-Corporation?

Yes, partnerships can elect S-Corporation status, but it requires terminating the partnership and forming a corporation. Alternatively, you can contribute partnership interests to a new corporation and elect S-Corp status. We analyze whether S-Corp election makes sense based on your self-employment tax exposure and administrative burden. Learn more about LLC vs S-Corp.

What happens if I miss the partnership tax deadline?

Missing the Form 1065 deadline triggers penalties of $220 per partner per month (or partial month), up to 12 months. A 10-partner partnership filing 3 months late faces $6,600 in penalties. We help partnerships file late returns and request penalty abatement when reasonable cause exists.

Do partnerships need to file state returns?

Yes, most states require partnership returns if the partnership has nexus (business activity) in the state. Multi-state partnerships may need to file in multiple states and handle withholding obligations. Some states require composite returns that pay tax on behalf of nonresident partners.

What is a Section 754 election?

A Section 754 election allows partnerships to adjust the basis of partnership assets when a partner sells their interest or receives a distribution. This prevents new partners from being taxed on built-in gains they didn’t economically enjoy. The election remains in effect for all future years once made.
