Almost every K-1 season, a passive LP looks at their tax documents, sees a six-figure number in Box K, and asks the question this article is named for: does a partner get basis for nonrecourse debt — and if so, why doesn't that basis match the cash they actually wired into the deal? Box K shows their share of partnership liabilities. Box L shows their capital account, typically equal to their wired contribution. The two are not the same, they're not supposed to be, and the rules governing how nonrecourse debt flows into a partner's basis are why.

Basis matters because it controls two things that drive an LP's real-world tax outcome: how much partnership loss they can deduct against other passive income, and how distributions get taxed when they exceed cumulative capital invested. Nonrecourse debt — the kind that backs almost every agency-financed multifamily syndication — adds to basis for one of those purposes but not the other. That asymmetry, plus the partner-versus-LLC-member question that surfaces alongside it, is where most LPs (and a fair number of CPAs) lose the thread.

This article walks the framework from an operator's perspective: how basis works, the distinction between recourse, qualified nonrecourse, and plain nonrecourse debt, how each flows through to a limited partner, and where Willowdale's actual debt structures land. The goal is a working mental model — not tax advice. Specific situations always go to your CPA.

What is Basis?

Basis is the IRS's record of what the partner has “invested” in the partnership for tax purposes — but the definition is broader than the cash they wired in. It starts with the contribution (cash plus the tax basis of any property contributed), and then it moves: it goes up when the partnership earns income, when the partner makes additional contributions, and when their allocable share of partnership debt increases. It goes down when they take distributions, when the partnership loses money, and when their share of debt drops. At any given moment, a partner's basis is the running sum of those events.

Two things make basis worth tracking for a limited partner. First, it caps the amount of partnership loss the partner can claim on their personal return in any given year. Pass-through losses — including the large depreciation losses that make multifamily syndication tax-efficient in the first place — can't exceed basis. Second, it controls how distributions are taxed: distributions up to basis are a tax-free return of capital; distributions in excess of basis are taxable as capital gain. The IRS publishes the rules in Topic 703 and Publication 541, but the practical version for an LP is shorter — basis is the ledger that determines whether your losses pass through and whether your cash distributions stay nontaxable.

One detail that catches LPs reading their K-1 for the first time: basis is not the same as the capital account shown in Box L, and it is not the same as the partner's share of liabilities shown in Box K. Capital account follows book accounting (partnership-agreement-driven). Basis follows tax accounting. The two start at the same place — the contribution — and drift apart almost immediately, mostly because of debt allocations.

What is Qualified Non-Recourse Debt?

Partnership debt falls into three tax buckets that determine how it flows to partners' basis: recourse, qualified nonrecourse, and plain nonrecourse. The dividing line is who bears the economic risk of loss if the loan defaults — the partnership, a specific partner, or no individual at all.

Recourse debt is debt where at least one partner bears the economic risk of loss — meaning if the partnership defaults, the lender can pursue that partner's personal assets. Recourse debt allocates entirely to the partner who bears the risk, and it raises both that partner's distribution basis and their at-risk basis.

Qualified nonrecourse debt is the carve-out that makes leveraged real estate work for LPs. To qualify under IRC §465(b)(6), the debt has to be (a) secured by real property used in the activity, (b) borrowed from a qualified person — an unrelated commercial lender, an insurance company, or a government agency — and (c) on terms where no individual is personally liable. Almost every agency loan from Fannie Mae or Freddie Mac on a multifamily property qualifies, which is why this category dominates the multifamily syndication landscape. Qualified nonrecourse debt allocates to partners by profit-sharing ratio and — critically — raises both distribution basis AND at-risk basis. That second piece is what lets LPs deduct depreciation losses that exceed their cash investment.

Plain nonrecourse debt — nonrecourse debt that is not qualified — is the residual: secured loans where no individual bears liability but the lender or the loan terms don't meet the §465(b)(6) tests (loans from a related party, loans secured by personal-use property, certain seller-financed structures). It allocates to partners by profit-sharing ratio and raises distribution basis, but it does NOT raise at-risk basis. That's the asymmetry referenced in the intro, and it's the reason LPs occasionally see their depreciation losses suspended at the at-risk wall instead of flowing through.

Does a Partner get Basis for Nonrecourse Debt?

Yes, a partner gets basis for nonrecourse debt — but the type of basis the debt creates depends on whether the debt is qualified, and that distinction has real consequences for what shows up on the LP's tax return.

For distribution purposes — meaning whether a cash distribution is tax-free or taxable as capital gain — both qualified nonrecourse and plain nonrecourse debt increase the partner's basis. The LP's share of the loan is treated as a deemed contribution. If the partnership refinances and pulls out equity to distribute pro-rata to LPs, that distribution is tax-free to the LP as long as their basis (including their share of nonrecourse debt) covers it. Mill Gardens, our 69-unit Warner Robins property and Willowdale's first multifamily, is the textbook example — we refinanced the property roughly 15 months post-close and returned 62.5% of investor capital. That distribution was nontaxable to the LPs because their basis, properly inclusive of their pro-rata share of the new agency loan, well exceeded the cash they received.

For loss-deduction purposes — meaning whether the LP can use a depreciation pass-through to shelter other passive income — the answer narrows. Only qualified nonrecourse debt raises at-risk basis. Plain (non-qualified) nonrecourse debt does not. If the partnership's debt is a regular agency loan from Fannie or Freddie, it qualifies, at-risk basis rises with it, and the LP can usually deduct their full share of pass-through losses (subject to the separate passive-activity rules under §469, which is a different limitation). If the debt is non-qualified, the at-risk rules in §465 cap losses at the cash-plus-recourse-debt the LP actually has on the line.

The disconnect that confuses LPs in K-1 season is this: Box K shows the LP's share of partnership liabilities — frequently a six-figure number tied to the property's nonrecourse mortgage — but that number is not the LP's basis. It's an input to basis. Capital account in Box L is yet another number, tracking book contributions and distributions. None of the three figures equal each other after year one, and they're not supposed to. The LP's CPA reconciles the three to compute the tax-relevant basis that gets applied to losses and distributions on the personal return.

Can a Limited Partner Guarantee a Loan?

Yes — a limited partner can sign a personal guarantee that voluntarily exposes them to recourse on partnership debt. In practice, in a multifamily syndication, this almost never happens. The reason LPs are LPs is precisely because they want capped, defined-dollar exposure. The day an LP signs a personal guarantee, they've stepped outside the limited-liability shield the structure was built to provide.

The partners who do sign personal guarantees are the GPs — the general partners or managing members of the sponsor LLC. On agency-debt multifamily deals, the GPs typically sign a bad-boy carveout — a narrow guarantee that triggers only on specific bad acts (fraud, voluntary bankruptcy filing, environmental misrepresentation, lying on the loan application). The loan is nonrecourse to the partnership and to LPs in every normal scenario. On non-agency nonrecourse deals where Marco and I have personally signed bad-boy carveouts, the structure works the same way — a narrow trigger on specific bad acts, with LPs insulated from everything else by the LP form itself.

Can Recourse Debt Be Pursued in a Limited Partnership?

If a limited partnership defaults on a recourse loan, the lender can pursue (a) partnership assets and (b) any partner who has personally guaranteed the debt. The LPs who haven't signed a guarantee are protected — that's the entire structural purpose of the LP form. General partners or managing members of the sponsor entity, to the extent they've signed guarantees, are on the hook up to the guarantee amount.

The lender-by-lender posture varies more than the textbook treatment suggests. On the regional and community-bank side — the lenders that finance smaller multifamily deals, value-add bridges, and most rehab-heavy first acquisitions — the majority will ask any sponsor with more than 20% ownership in the deal to sign a personal recourse guarantee. That's a position both Marco and I have negotiated on Willowdale's debt repeatedly. Agency lenders (Fannie Mae and Freddie Mac, through the DUS and Optigo programs) are the cleaner counterparty here: they run nonrecourse across the board on the institutional product, with only the bad-boy carveouts described above. CMBS and life-company lenders sit somewhere in between, deal-by-deal. The lender choice on a given acquisition is partly a recourse-posture choice — which is one of the structural decisions that affects the LP's risk profile before the cap-rate and rent-growth assumptions ever enter the picture.

How to Avoid Personal Liability

The clean answer for a limited partner is: invest as an LP in a syndication where the sponsor signs the debt. Don't sign a personal guarantee. The capped-dollar exposure baked into the LP structure is the asset, and you defeat it the moment you put a personal signature on the loan documents. On the sponsor side, the answer is harder — most lenders won't finance a deal without some personal liability somewhere on the loan, and the trade-off is real.

The way an operating sponsor reduces (not eliminates) personal liability over time is by graduating from regional-bank recourse debt to agency nonrecourse debt as the track record builds. Agency lenders underwrite the property's NOI and the sponsor's experience; once a firm has executed business plans at scale, it qualifies for nonrecourse agency product where the only personal exposure is the bad-boy carveouts. Willowdale's current portfolio runs on agency-style nonrecourse debt — the structural move every sponsor makes as the firm scales, replacing the personal-guarantee-for-the-full-loan posture of early-stage deals with the narrow bad-boy carveout structure agency lenders require.

The other agency-side detail worth knowing for LPs: because the loan is nonrecourse to the partnership and not to any individual LP, the at-risk basis flow described earlier kicks in — the LP gets pass-through depreciation losses backed by qualified nonrecourse debt without having any actual recourse exposure on the loan. That asymmetry is the structural feature that makes leveraged multifamily syndication work as a tax-advantaged passive vehicle in the first place.

Bifurcated Liability

Some lenders structure debt as partially recourse and partially nonrecourse — bifurcated liability in tax parlance. A $1M loan might carry a $100K personal guarantee on the GP and be otherwise nonrecourse. The recourse slice flows to the guaranteeing partner's basis as recourse debt; the remainder flows to all partners pro-rata as nonrecourse. Bifurcated structures show up most often in bridge debt, recapitalization deals, and edge cases where a lender wants more skin in the game than a pure-nonrecourse loan would require but the sponsor isn't willing to guarantee the whole stack. For an LP, the practical implication is the same: the LP doesn't sign anything, the partial recourse rides on the GP, and the LP's basis treatment runs through the qualified-nonrecourse rules described above for the nonrecourse portion.

Frequently Asked Questions About Partners Getting Basis for Non-Recourse Debt

Nonrecourse Debt and Basis for Limited Partners - Conclusion

Basis for nonrecourse debt is the seam in the partnership tax code that makes leveraged multifamily syndication work as a tax-efficient passive vehicle. Qualified nonrecourse debt — almost always the agency loan secured by the property — flows into a limited partner's basis for both distribution and at-risk loss purposes, which is how an LP gets to deduct depreciation losses that exceed their cash investment AND receive nontaxable refinance distributions backed by that same loan. Plain nonrecourse and recourse debt sit on either side of that sweet spot. The category an investor sits in is determined by the sponsor's debt selection, not anything the LP signs.

For an LP reading their K-1 for the first time, the practical takeaways are: Box K is your share of partnership debt, Box L is your capital account, neither equals your basis, and your CPA reconciles all three to compute the real tax position. For a sponsor, the operating discipline is to graduate the firm's debt over time toward agency nonrecourse structures — which is what protects both the firm's personal balance sheet and its LPs' loss pass-through eligibility at the same time.
