How can I submit an amendment to K-1's I generated for my partnership return?
So I'm in a bit of a tax mess. Last year my buddy and I started what we thought was just a fun side project, but apparently we accidentally created a partnership for tax purposes (yay!). I managed to file the partnership return by the March 15th deadline, but now there's a problem. My personal accountant (who doesn't handle partnerships) just pointed out that I completely missed filling in box 14 on the Schedule K-1 forms. He's refusing to start on my personal taxes until I fix this partnership return issue. I've been searching all over trying to figure out how to submit an amended return for a partnership. Most resources I find only talk about amending Form 1065, but I specifically need to know how to amend the K-1s for both myself and my partner. For context, this is a really small operation - the partnership had less than $6,500 in gross income and about $6,000 in expenses for the year. I'd like to handle this with minimal time and expense if possible. Anyone have experience with amending partnership returns? Any guidance would be seriously appreciated!

You'll need to file an amended Form 1065 using Form 1065X to correct the Schedule K-1s. The K-1s are generated as part of the 1065, so you can't just amend the K-1s separately - you have to amend the entire partnership return. To amend a partnership return, follow these steps: 1. Complete a new Form 1065 with the corrected information (marking it as "Amended Return") 2. Generate new Schedule K-1s with the correct box 14 information 3. Include a statement explaining the specific changes you're making to the return 4. File Form 8977 (Partnership Representative Revocation/Designation) if needed Most tax software should allow you to prepare an amended return. Since your partnership is small, this shouldn't be too complex - you're just adding information to box 14, not changing any financial data. Box 14 is for self-employment tax information, which your personal accountant likely needs to properly complete your individual return.

AuthorThanks for this! Quick follow-up: so I just need to check the "Amended Return" box on a new 1065 form and include all the same info as before but with box 14 completed? Do I need to include any forms specifically stating what changed between filings? Also, is this something that tax software like TurboTax can handle, or am I better off going to a professional? I'm just worried about the cost.

Yes, you'll check the "Amended Return" box on a new 1065 and include all the same information as before, but with box 14 properly completed. You should also attach a statement explaining exactly what changes you made (in your case, "Added self-employment tax information to Box 14 of Schedule K-1"). Most tax software can handle partnership amendments, including TurboTax Business or H&R Block Premium & Business. Since you're only making a simple change to Box 14 without altering any financial information, you could reasonably do this yourself with tax software if you're comfortable with it. The software will walk you through generating the corrected K-1s. If your partnership is truly small with straightforward income and expenses as you mentioned, DIY with tax software might be the most cost-effective option. However, if you're uncertain, a one-time consultation with a CPA who handles partnerships might be worth the peace of mind.

After struggling with a similar partnership amendment situation last year, I discovered taxr.ai (https://taxr.ai) which was super helpful for figuring out exactly what forms I needed and how to file them correctly. It analyzes your specific tax documents and explains what you need to do in plain language. I used it when I had to amend our Schedule K-1s because we messed up some passive activity codes. It guided me through the whole amendment process, explained which boxes needed to be fixed, and helped me understand what statements needed to be attached to avoid issues with the IRS.

Does taxr.ai work with partnership returns? I've used other tax help services before but they usually only cover basic individual returns. The partnership stuff seems way more complicated. Can it actually help with amending a 1065 and K-1s?

I'm skeptical about these AI tax tools. How does it actually work with partnership returns? Does it just give generic advice or does it actually look at your specific forms? My accountant charges $300 just to look at an amendment, so I'd consider alternatives if they actually work.

The service analyzes partnership returns including Form 1065 and Schedule K-1s. It's not just for basic individual returns - it specializes in more complex situations like partnerships, S-corps, and other business entities. It's not generic advice - you upload your specific tax documents and it analyzes your actual forms to identify what needs to be fixed. For my K-1 amendment, it pinpointed exactly which boxes were incorrect and the specific information needed to correct them, then guided me through completing the amended return properly.

I tried taxr.ai after my initial skepticism, and I have to admit it was surprisingly helpful. I uploaded my partnership return and it immediately identified the issue with box 14 missing on the K-1s and walked me through the exact amendment process. The document analysis pointed out that I needed to use Form 1065-X rather than just submitting a corrected 1065 (which is what I was planning to do incorrectly). It saved me from making an additional mistake! The step-by-step guidance for completing the forms with the proper codes for box 14 was clear and actually made sense. I was able to complete the amendment myself without paying my accountant the $300 consultation fee. Definitely worth checking out if you're dealing with partnership amendments.

If you're struggling to get through to the IRS for help with your partnership amendment, I had great success using Claimyr (https://claimyr.com). After spending hours on hold trying to get specific questions answered about my partnership amendment, I discovered this service through a YouTube demo (https://youtu.be/_kiP6q8DX5c). It got me connected to an actual IRS agent in about 20 minutes instead of the 2+ hours I was waiting before. The agent was able to confirm exactly what forms I needed for my partnership amendment and clarified some confusing instructions about box 14 reporting requirements.

Wait how does this even work? The IRS phone lines are notoriously impossible to get through. Is this service actually legitimate or just another scam trying to get money from desperate taxpayers?

This sounds too good to be true. I spent literally 3 hours on hold with the IRS last week trying to get help with a partnership issue and eventually gave up. There's no way something can just magically get you through the queue... the IRS phone system is a disaster.

It uses call technology that navigates the IRS phone system and waits on hold for you. Once an agent is about to pick up, it calls you and connects you directly with them. It's completely legitimate - it's just automating the hold process so you don't have to waste hours with a phone to your ear. I was skeptical too, but it literally saved me hours of wait time. The service doesn't access any of your personal tax information - it just handles the phone connection part. They use the same public IRS phone numbers anyone would call, they just have technology to manage the waiting for you.

I take back what I said earlier. After another failed 2-hour hold attempt with the IRS yesterday, I tried Claimyr out of desperation. Within 25 minutes I was talking to an actual IRS representative who walked me through exactly what I needed for my partnership amendment. The IRS agent confirmed I needed to file Form 1065-X for the amendment and explained exactly what to include in Box 14 for self-employment income. They also gave me the correct mailing address for partnership amendments and confirmed I didn't need to file Form 8977 since I wasn't changing the partnership representative. This saved me from hiring a professional and gave me the confidence to handle the amendment myself. After months of frustration, I finally have clear direction on exactly what to file.

Be really careful with amendments and make sure you're using the correct form. The IRS updated the amendment process for partnerships in recent years. For tax years beginning on or after 1/1/2018, you generally use Form 1065-X. For prior years, you file an amended Form 1065 with the "Amended Return" box checked. Also make sure you're using the correct income and expense codes for Box 14. That's probably what your accountant is concerned about - without proper coding in Box 14, your self-employment tax calculation could be wrong on your personal return.

AuthorThanks for the heads up! What specific codes should I be looking for in Box 14? My accountant wasn't super clear on what exactly was missing, just that Box 14 needed to be filled out. Our "business" is basically just selling handmade stuff online, if that helps.

For a small online selling business, you'll likely need code A for "Net earnings (loss) from self-employment" in Box 14. This is the most common code for small partnerships where the partners are actively involved in the business. If you have any guaranteed payments, those would be reported with code C. There are other codes for things like gross farming/fishing income, but for a simple online selling business, code A is typically what you need. Make sure the amount you enter matches the partner's share of ordinary business income from Box 1, minus any items that aren't subject to self-employment tax. Your tax software should calculate this correctly if you enter the information about your business activities properly.

As someone who made this exact mistake last year, let me tell you what worked for me. I used FreeTaxUSA which handles partnership returns for a reasonable price. To amend: 1. Create a new 1065 return in the software 2. Enter all the same info as your original return 3. Check the "Amended Return" box 4. Make sure to complete Box 14 this time 5. The software will generate the proper K-1s It's actually not as complicated as it seems. For a simple partnership with low income/expenses like yours, the amendment should be straightforward as long as you're just adding the Box 14 info and not changing any dollar amounts.

Did you file electronically or by mail? I've heard conflicting info about whether partnership amendments can be e-filed or if they have to be mailed in.

Partnership amendments generally need to be mailed - most tax software doesn't support e-filing for amended partnership returns yet. I had to print and mail mine to the IRS processing center. Make sure to use certified mail so you have proof of delivery, and keep copies of everything for your records. The IRS website has the specific mailing addresses for partnership returns by state.

Just wanted to add my experience since I went through this same headache last year. The key thing that helped me was understanding that Box 14 is specifically for self-employment tax calculations - that's why your personal accountant won't touch your individual return until it's fixed. For a simple partnership like yours (selling stuff online), you'll most likely need to report your share of the partnership's net earnings in Box 14 with code "A". Since you mentioned $6,500 gross income and $6,000 expenses, your net earnings would be around $500, so each partner's Box 14 would show their respective share of that amount. I used TurboTax Business to handle my amendment and it was pretty straightforward. The software automatically calculated what needed to go in Box 14 based on the business income I'd already entered. Just make sure when you generate the new K-1s that both you and your partner get copies of the corrected versions for your personal returns. One tip: call the IRS processing center after you mail the amendment to confirm they received it. Mine got lost in the mail the first time and I had to resend everything.

This is really helpful! Just to clarify - when you say "each partner's Box 14 would show their respective share," how exactly is that calculated? Is it just split 50/50 since there are two partners, or does it depend on ownership percentages? Also, regarding calling the IRS processing center - do you happen to remember which number you called? I want to make sure I'm calling the right place once I send mine in. @Ravi Kapoor Thanks for sharing your experience with this!

The Box 14 allocation depends on each partner's ownership percentage in the partnership, which should match what you reported in the "Partner's Share of Profit, Loss, and Capital" section of the original K-1s. If you and your partner split everything 50/50, then yes, each Box 14 would show half of the net self-employment earnings. For the IRS processing center, I called the general partnership tax line at 1-800-829-0115, but honestly the wait times were brutal. That's actually why I ended up trying one of those callback services someone mentioned earlier - it saved me hours of sitting on hold just to confirm they received my paperwork. Make sure you keep detailed records of when you mailed the amendment and follow up if you don't hear anything within 8-12 weeks. The IRS processing times for partnership amendments can be really slow.

The calculation depends on your partnership agreement and ownership percentages. If you and your buddy are 50/50 partners, then yes, you'd each get half of the $500 net earnings ($250 each) in Box 14. But if your partnership agreement specifies different ownership percentages or profit-sharing arrangements, you'd use those instead. For the IRS processing center, I called the general partnership line at 1-800-829-4933 and asked to be transferred to the processing center that handles partnership returns for my state. They were able to track the status of my amendment and confirm receipt. You can also check the IRS website for the specific processing center address where you mailed your return - they usually have direct numbers listed. Just make sure you have your EIN and the date you mailed the amendment when you call. It can take 8-12 weeks for them to process partnership amendments, so don't panic if you don't hear back right away.

The share calculation depends on your partnership agreement and ownership percentages. If you and your buddy are equal partners (50/50), then yes, you'd each report half of the net earnings in Box 14. But if you have different ownership percentages (like 60/40), it would be split accordingly. Since you mentioned this started as an accidental partnership, you might not have a formal partnership agreement specifying ownership percentages. In that case, the IRS generally assumes equal partnership interests unless you can document otherwise. For the IRS processing center number, I called the general business tax line at 1-800-829-4933. They can look up your partnership by EIN and confirm receipt of amendments. Just be prepared for long hold times - that's where services like Claimyr that others mentioned can be helpful. @Noah huntAce420 Hope this helps clarify things!

The partnership share depends on how you set up the partnership agreement and what percentage each partner owns. If you're 50/50 partners (which sounds likely since you mentioned "my buddy and I"), then yes, you'd split the Box 14 amount equally. So if your net self-employment earnings are $500 total, each partner would show $250 in Box 14. However, if you have different ownership percentages or profit-sharing arrangements, it would be split accordingly. Check your partnership agreement or think about how you originally agreed to split profits/losses. For the IRS processing center, I called the general partnership line at 1-800-829-4933, but honestly I had better luck using the callback services others mentioned in this thread. The regular IRS lines are brutal to get through to. When you do get connected, ask for the "partnership unit" and have your EIN ready. @Noah huntAce420 No problem! This stuff is confusing enough without having to figure it out alone.
