Question about portfolio deduction with K-1

I received a K-1 for an exchange fund where I contributed appreciated stock with low basis to diversify them. My K-1 shows interest income, dividend income, capital loss(9a), investment expense (line 13 code H) , portfolio deduction (line 13 code AE).

 

Initially Turobtax did at-risk calculations Form 6198.  The Part 1 Line 4 showed  capital loss + investment expense. The portfolio deduction was not part of it, as I understand they used to be deductible with 2% AGI floor but recent law prohibits it, so makes sense not to include it in Line 4.

 

However, during final checks, Turbotax flagged that portfolio deduction amount (K-1 line 13 with code AE) should be accounted for in the K-1 additional worksheet. This worksheet seems to have gotten added during this final check. Box 13 line 9 (under other deductions) showed this amount, so I selected line 2 for itemized misc deduction 2% floor. This resolved the flag but my Form 6198 got updated and its Part 1 Line 4 now includes portfolio deduction amount. This results in lowering my refund, it seems allowed loss against at-risk gets allocated towards portfolio deduction which is anyways not deductible. So in other words portfolio deduction is being allocated the allowed loss part which I can not deduct anyways.

 

Any ideas how to resolve this? If Turbotax did not flag during final review - it was how I expected. Am I missing something?

I believe that’s for the At-Risk worksheet (Form 6198). Do you have Form 6198 in your list of forms?

You are right, Turbotax has opened Form 6198 for doing at-risk calculation(I had a typo in my original post, but fixed it now).

 This form initially looked fine only including loss + investment expense in Part 1 line 4. Later when Turbotax flagged about portfolio deduction amount in the additional K-1 worksheet (which it added on final review initially it was not there), I was forced to add the portfolio deduction amount in Box 13 line 2 - but it changed 6198 to include portfolio deduction in Part 1 Line 4 resulting in my refund going down.

 

The portfolio deduction is not deductible anymore (used to be it seems), why is it getting added in Part Line 4 of form 6198. Can I avoid it?

OK, so did you have a loss where you were not at-risk? Otherwise, your refund should not have been impacted.

Yes, I had loss and not all my investment was at risk due to non-recourse loan addition.

 

The form 6198 can help Turbotax know at-risk limitation for how much loss is allowed. But for outside basis limitation for loss deduction, how does Turbotax find that out. The dialogue for K-1 only asks information I received in K-1 form, but it nowhere asks outside cost basis I am tracking. How would Turbotax know how much of loss specified in K-1 is limited by basis I am tracking?

The program wouldn’t know your outside basis automatically. I suppose it could calculate your outside basis if you fed it the correct and relevant information since the investment was initiated, such as your beginning basis, capital contributions, shares of your income/loss/liabilities, and distributions. Frankly, I’m not sure how much of that TurboTax tracks from year to year and then retains.

While the portfolio deductions may not be currently deductible, these do impact your basis and at-risk.  This is the same impact that other nondeductible items on the K-1 reduced basis and at-risk in past years as well (meal & entertainment, etc. your share reported on the K-1).

If the items are not deductible, then you should not be able to “increase” your basis and at-risk in order to be able to take additional ordinary losses (increase by not reducing your basis and at-risk).

Thanks for the response. Looks like portfolio deduction even if not deductible will eat into the allowed loss after at-risk limited allowed loss calculation.

Can you also please clarify when we enter the K-1 details into Turbotax, should we simply enter what numbers we see in received K-1? I track my outside cost basis, and Turbotax does not know it. One option that comes to my mind is that if my outside basis is 1000, I allocate this loss proportionally against all deductions (like actual loss, investment expense) and enter only the adjusted actual loss, investment expense into Turbotax, instead of directly copying these values from received K-1?  I am using TurboTax Premier, I wonder if this is not the right solution to handle K-1.

Glad to hear you track your tax basis separately.  Most don’t until it becomes a crisis.

We have to remember that TT is designed for the “masses” and when complicated situations arise, sometimes workarounds need to be used.  Having said that, it appears that once you entered the details and prepared form 6198, the software arrived at the appropriate allowable loss?

Using the TT software and form 6198 should provide you with the correct allowable loss and also tracks unallowed losses.  You appear to be sophisticated to where you can review your tax return to determine if TT is providing the correct end result.

You also have to keep in mind that when you are looking at “outside basis” you are most likely really looking at your “at-risk”.  This is because outside basis includes non recourse liabilities which is not included for your “at-risk”.

As a separate note, who is preparing the tax return for the exchange fund?

There is an exception for the usual nonrecognition of gain upon contributions of property to a partnership under Section 721.

Did anyone look at the impact of Section 721(b)?

It’s beyond the scope of a forum such as this, but definitely needs to be addressed.

13H is investment interest expense, which is deductible on schedule A, Form 4952 (you must itemize) but the deductible amount is limited to investment income any excess is a carryover. 13 AE is portfolio deductions which are no longer deductible for federal purpose but some states with a personal income tax still allow it. Input is done on the federal k-1.

at risk can at time be different than tax basis. net losses are limited to the lower of basis or your at-risk amount. Form 6198 only computes at-risk amount.

sorry basis and at-risk go down by non-deductible items like 13AE and even 13H if you don’t itemize or the deductible amount is limited. This which also include nondeductible expenses on line 18 and distributions on line 19  

Under IRC Sec 721 since no gain or loss is recognized upon acquiring the interest for that stock. That’s an issue that will be address later

TurboTax does not calculate basis only at-risk - Form 6198. 

So here’s how it works. you beginning basis and at-risk is your tax basis in the stock. You add net income and subtract net loss as reflected in the capital account analysis. You also subtract any distributions (this might create a problem because you stock basis and its FMV differ). Here’s what is not clear from the Form 6198. Since this seems to be the first year you invested in the partnership you at-risk amount goes up by your share of the ending liabilities of that partnership that qualify to be included in at-risk.

 

 Amounts Not at Risk You are not considered at risk for any of the following.

1. Nonrecourse loans used to finance the activity or to acquire property used in the activity. However, you are considered at risk for qualified nonrecourse financing secured by real property used in the activity of holding real property (other than mineral property).

2. Cash, property, or borrowed amounts used in the activity that are protected against loss by a guarantee, stop-loss agreement, or other similar arrangement (excluding casualty insurance and insurance against tort liability).

3. Amounts borrowed for use in the activity from a person who has an interest in the activity other than as a creditor or who is related under section 465(b)(3)(C) to a person (except you) having such an interest. However, this does not apply to (a) amounts borrowed by a corporation from a person whose only interest in the activity is as a shareholder of the corporation, or (b) amounts borrowed after May 3, 2004, and secured by real property used in the activity of holding real property (other than mineral property) that, if nonrecourse, would be qualified nonrecourse financing. See Pub. 925 for definitions.

4. Any cash or property contributed to the activity or to your interest in the activity that is: a. Financed through nonrecourse indebtedness or protected against loss through a guarantee, stop-loss agreement, or other similar arrangement; or b. Borrowed from a person who has an interest in the activity other than as a creditor or who is related under section 465(b)(3)(C) to a person (except you) having such an interest. However, this does not apply to (i) amounts borrowed by a corporation from a person whose only interest in the activity is as a shareholder of the corporation, or (ii) amounts borrowed after May 3, 2004, and secured by real property used in the activity of holding real property (other than mineral property) that, if nonrecourse, would be qualified nonrecourse financing. See Pub. 925 for definitions.

Built-In Gain and Loss Property - the difference between the contributing partner’s tax basis in the asset and it’s fair value
A “built-in” gain or loss is the difference between the fair market value (FMV) of property and its adjusted tax basis. By contributing property with a built-in gain or loss, the contributing partner effectively defers recognition until the property’s disposition or until another triggering event.

Built-In Gains
• Example: Partner A contributes stock with an FMV of $200,000 and a basis of $100,000; there is $100,000 of built-in gain. Under §721, no gain is recognized on contribution. If the partnership later sells the stock for $210,000, the built-in gain of $100,000 (plus any additional appreciation) is recognized and specially allocated back to Partner A under §704(c).
• Accelerated Recognition: Certain transactions (e.g., distributions to other partners or subsequent property sales) may trigger recognition of the built-in gain earlier than expected under regulations aiming to preclude shifting built-in gain to other partners.

Built-In Losses
• Example: Partner B contributes stock with an FMV of $80,000 and an adjusted basis of $120,000; there is a $40,000 built-in loss. The partnership’s inside basis remains $120,000, but for tax accounting and future allocations, that $40,000 built-in loss is associated with Partner B. Should the partnership sell the property at its contributed value of $80,000, that $40,000 loss is allocated to Partner B.
• Loss Limitation: If the partnership is unlikely ever to sell the property for an amount lower than $120,000, Partner B’s built-in loss essentially remains unrecognized (and effectively “stranded”) within the partnership. Additionally, Congress has enacted provisions to limit the recognition of a built-in loss if the property has significantly declined in value before contribution, restricting potential tax benefits.

To be honest with you, I did not have any non-recourse liability added in my K-1, so ideally I should not need to fill form 6198. I still went ahead and filled as it was the only way I could make Turbotax do some sort basis checks wrt how much loss/investment-expense I can deduct.

I wish Turbotax allowed us to enter tracked cost basis from our side so it would correctly calculate if there is any 704(d) suspended loss, and then 704(d) allowed loss could be subject to at-risk limitation ONLY IF form 6198 is required to be filled. One workaround in my mind was to adjust loss and investment expense on our own before entering into the Turbotax instead of directly copying these from K-1. Interestingly for Box 1 ordinary loss, Turbotax does say to adjust it to not exceed basis, but it does not say same when entering capital loss or 13AE investment expense or 13H portfolio deduction.

it doesn’t and probably never will(maybe) but Intuit’s professional software like Lacerte and ProSeries do, as does, most if not all, professional software. Most practitioners will even send out the basis calculation with the K-1. Probably the reason is Intuit doesn’t is because it doesn’t trust you to know all the rules that affect basis. and putting those questions into the app for some reason. The “maybe” is because the IRS at some point might require the calculation to be included with 1040s as it does for S-Corporations under certain conditions. You could also read the K-1 instructions which does provide instructions for calculating basis. THERE’S EVEN A WORKSHEET ON PAGE 6. LIABILITIES ARE THE TRICKY THING. 

INFO ON CALCULATING BASIS 2025 STARTING ON PAGE 

Schedule L on the k-1 is supposed to be tax basis so if this is true, then you take ending capital and add your share of ending liabilities (Part II section K) that you can include. In the following year, from ending capital you subtract those beginning liabilities and add the appropriate ending liabilities
