How do I know my tax basis from final K-1?

I would really appreciate guidance from some of the K-1 experts here:

In 2025 I sold my entire interest in a partnership that invested in real estate. I'm unclear on how to compute the tax basis for my interest based on the info on the final K-1. I actually received 53,946 for the sale of my partnership interest. The K-1 reports the following as my capital account info for 2025:

Beginning capital account: -63,279

Current year net income (loss): -7,464

Other increase (decrease): 70,743 [the explanation for this amount is the sale of my interest, even though I actually received 53,946]

Ending capital account: 0

Is my tax basis the capital account balance immediately before the sale of my interest, i.e. -63,279 - 7,464 = -70743? So my gain on the sale of the interest is 53,946 - (-70743) = 124,689?? What am I missing?

Please also note that my share of the partnership's nonrecourse and qualified nonrecourse financing totaled 206,448 immediately prior to the sale of my interest. This matches a "distribution" of 206,448 reported in box 19D of the K-1, which I expect just offsets the basis I had due to my share of the partnership's liabilities -- in other words, it doesn't affect my basis for tax purposes.

I would appreciate any help or guidance! Thank you

1) You should have a calculation of your outside basis that would include the allocation of partnership liabilities. This is your beginning basis before the other changes.

2) The reduction in your share of the partnership liabilities would then reduce your basis in the same way that a cash distribution would. This is an adjustment to your outside basis.

3) The "deemed" distribution is another name for the reduction in liabilities. You would not account for this transaction twice. This is how the partnership records the adjustment to your inside basis.

If the reduction in liabilities brings your outside basis to zero, any additional reduction would be taxed as capital gain. Likewise, if you have no remaining basis, the entire amount of any sales proceeds would result in a capital gain as well.

See IRS Pub 541 Sale, Exchange or Other Transfer of Partnership Interest for a discussion of how to report this transaction.

The Capital Account Analysis shown on the final K-1 Section L is the "inside" basis, which may not be your actual "outside" basis. The partner's capital account measures the partner's equity investment in the partnership. The outside basis measures the adjusted basis of the partner's partnership interest.

A summary calculation of your outside adjusted basis would be:

+ contributions (including increases to the partner’s share of liabilities)

+ taxable income + tax-exempt income

– distributions (including decreases to the partner’s share of partnership liabilities)

– taxable losses + nondeductible expenses.

Your gain or loss on the sale would be:

+ sales proceeds

– selling expenses

– your outside basis.

You may wish to use the worksheet provide by the IRS to assist in tracking basis: Worksheet for Adjusting the Basis of a Partner's Interest in the Partnership.

This worksheet includes all elements that need to be included in the basis calculation, including those items that are not used by the partnership for Schedule K-1 Section L.

PatriciaV,

Thank you very much for your informative response -- this is very helpful. I have two follow-up questions if possible:

Because I sold my interest in the partnership, the final K-1 reports that my share of the partnership's liabilities went from $206k to zero, and the partnership made a "deemed" distribution of $206k to me (code 19D):

1) To calculate my basis for the purpose of determining my gain on the sale of my interest, do I use the basis immediately before my share of pship liabilities went to zero? Or should I take into account the reduction of my share of liabilities from $206k to zero? (The latter approach would leave me with an adjusted basis of zero, and in fact the 206k is more than what I believe my basis was.)

2) How do I handle the $206k "deemed" distribution? To the extent the $206k deemed distribution exceeds my final basis, do I treat this excess amount as "gain" in addition to the sale proceeds I actually received for the interest I sold?

Thank you!
