Personal Guarantees and Partnership Tax: How They Affect Your K-1

Roger Ledbetter, CPA · 2026-02-26 · 4 min read

A personal guarantee on a partnership loan changes how that debt is allocated on the K-1. It converts nonrecourse debt into recourse debt for the guaranteeing partner, which increases their outside basis. This affects their ability to deduct losses and can be a useful planning tool when coordinated with the operating agreement.

How Do Personal Guarantees Work in Partnerships?

When a partner provides a personal guarantee on a partnership loan, they are agreeing to repay the lender if the partnership cannot. From the IRS's perspective, that partner now bears the economic risk of loss on the guaranteed portion of the debt.

This changes the debt classification. Without the guarantee, a typical commercial real estate loan secured only by the property is nonrecourse. With the guarantee, it becomes recourse to the extent of the guarantee, and the guaranteeing partner receives the liability allocation.

How Does This Affect the K-1?

The K-1 reports each partner's share of partnership liabilities in three categories: recourse, qualified nonrecourse, and nonrecourse. The guaranteed portion shifts from nonrecourse to recourse for the guaranteeing partner.

This matters because a partner's share of partnership liabilities is part of their outside basis. Higher basis means the partner can deduct more losses. In a real estate partnership with significant depreciation deductions, the additional basis from a personal guarantee can make the difference between deductible and suspended losses.

When Are Personal Guarantees Used as a Planning Tool?

The most common scenario is a partner who needs additional basis to deduct accelerated depreciation from a cost segregation study. The cost segregation generates large deductions in the early years of the deal. If the partner's basis from capital contributions and nonrecourse debt allocation is not sufficient, those deductions get suspended.

By providing a personal guarantee, the partner increases their recourse liability allocation, which increases their outside basis, which allows them to deduct the losses currently.

The operating agreement should address how personal guarantees interact with the partnership's economics. If one partner guarantees a loan, their increased liability allocation may affect the distribution waterfall and the allocation of income or loss to other partners.

What Are the Considerations?

Real economic risk. A personal guarantee is not just a tax planning tool. It is a real obligation. If the partnership defaults on the loan, the guaranteeing partner is personally liable. The tax benefit should be weighed against the actual risk.

Guarantee structure. Not all guarantees are the same. A full guarantee, a partial guarantee, a "bad boy" carve-out guarantee, and an environmental indemnity each have different implications for whether the debt is treated as recourse and how much liability is allocated.

Coordination with cost segregation. If the partnership is planning a cost segregation study, the timing of the personal guarantee relative to the study affects whether the partner has sufficient basis to deduct the accelerated depreciation in the first year.
