Thanks for mentioning this! You're right - there were actually a few extra pages that came with the K-1 that I ignored because they looked like gibberish to me. Just checked and they do have some explanations about the passive activity stuff. Would you recommend I still get professional help or is this something I can handle with tax software if I'm careful?

For a relatively simple K-1 showing only $3,800 in income, you can probably handle it with good tax software if you're careful. Since this is your first K-1, learning how to report it properly now will help you in future years. If the investment becomes more complex or involves much larger amounts, then professional help would be worthwhile. Just make sure you keep copies of all K-1s and supplemental information, as you'll need them if you ever sell your interest in the partnership to calculate your basis.

This is so important! I learned this the hard way too. Also worth noting that some states require estimated payments even if federal doesn't. My state has a much lower threshold for when you need to start making estimated payments.

Do you need to attach any kind of explanation to your return if you're reporting an amount different from the 1099? Or just be ready to explain if they ask later?

You don't need to attach an explanation to your electronic filing. Just be ready to explain if they ask later. The best approach is to keep detailed records of all your income - bank deposits, invoices, payment confirmations - so if there is a discrepancy, you can easily show why your reported amount is correct. For significant discrepancies (I'd say anything over $500), you might want to reach out to the company first to see if they'll issue a corrected 1099-NEC. But if they won't or you can't reach them, filing with your accurate records is the right move.

Use the most recent one they sent, but double-check it against your own records. Companies can issue corrected 1099s (they should be marked as "CORRECTED" on the form), but multiple corrections is definitely unusual and annoying.

That's a really good point I hadn't considered. So even though some of the partnership income was earned in 2023, I'm reporting all of it on my 2024 personal return because the partnership's fiscal year ended within my 2024 tax year? Does this create any issues if I also have to file foreign bank account reports (FBARs) or Form 8938? Do those forms follow the same rules?

Yes, that's exactly right. All of the partnership income from their complete fiscal year (June 2023-May 2024) goes on your 2024 personal return. That's just how partnership taxation works. For FBARs and Form 8938, those follow different rules. Those forms are based on the calendar year reporting and the maximum value of accounts during that calendar year. So your FBAR and 8938 for 2024 would cover January 1 to December 31, 2024, regardless of any partnership fiscal years.

The Taxpayer Advocate Service is really only for when you have an actual tax problem that hasn't been resolved through normal IRS channels. They probably won't help with just form questions unless you've already filed incorrectly and are having issues. Your best bet for form questions is either the regular IRS help line (if you can get through) or a qualified tax professional who specializes in international taxation.

Would you recommend mailing it certified so I have proof they received it? I've had stuff "lost" by the IRS before.

Absolutely use certified mail with return receipt. That gives you proof of when it was received and by whom. Keep a complete copy of everything you send (EVERYTHING) including the certified mail receipt. Also good practice to follow up by phone about 30 days after sending to confirm it's been received and assigned to someone. Ask for the status and document who you speak with. If you get nowhere with that call, wait 2 weeks and try again.

I did it in 2022 and got approved! The key is showing that you've been consistently treating the business as an S-corp in all your filings and operations. In my case I had filed corporate returns, taken reasonable salary, etc. They approved it retroactively even though I was like 18 months late with the election.

22 Thanks for the terminology correction! I always mess that up 🤦‍♂️ So to get a bigger refund, do I just put a specific dollar amount on line 4(c) of the W-4? Or do I need to change other parts of the form too?

7 Yes, line 4(c) on the W-4 is exactly where you'd put additional withholding. You can specify an extra amount to be withheld from each paycheck. As for how much to add, a rough calculation would be to decide how much extra refund you want, then divide by the number of pay periods remaining in the year. For example, if you want an extra $1,200 in your refund and get paid twice a month, you might put $50 in line 4(c) ($1,200 ÷ 24 pay periods = $50 per paycheck).

16 The standard deduction actually does increase with inflation each year. For 2025 it's $14,600 for single filers, up from $14,350 in 2024. The problem is that tax brackets also adjust with inflation, but when you get a big raise that outpaces inflation, you still move into higher brackets regardless. What really doesn't scale well are certain credits and deductions that start to phase out at higher income levels. That could be another factor in why OP's refund was smaller despite paying more tax.
