Thank you for the advice! I've already started working on my 2022 return and will file it this week. Is there any way to reduce the penalties since this is my first time making this mistake?

You can request penalty abatement under the IRS First Time Penalty Abatement policy if you haven't had any significant penalties in the past 3 tax years and have filed (or filed extensions for) all required returns. Call the IRS after you file and pay or set up a payment plan. Tell them you want to request "first-time penalty abatement" for reasonable cause. Explain that you misunderstood the withholding requirements with multiple jobs and that you've taken steps to correct it for the future. Many people get approved, especially for first-time mistakes.

You might want to update your W4 instead of just asking for extra withholding. If you use the IRS Tax Withholding Estimator online it'll tell you exactly how to fill it out for multiple jobs.

This is a really good point! In Texas they wanted an actual signed affidavit from the doctor instead of just a letter, and my friend almost got her state return rejected because of this difference.

I logged into my account and there's nothing about an outstanding balance or pending charges. Just looks normal. I've checked all email folders including spam - absolutely nothing from them requesting payment. My contact info is all current too. It's just weird that they haven't made any attempt to collect.

That's definitely unusual. Their automated system should have flagged your account by now. Most likely explanations: There's a glitch in their system that failed to flag your account as unpaid. This happens sometimes when the IRS changes delivery method without proper notification codes to the software company. The best ethical approach would be to contact them, but realistically, if you don't, there are two possible outcomes: either they'll eventually discover the error and bill you (could be weeks or even months), or it falls through the cracks permanently. I've seen both happen.

Do tax prep companies really send unpaid fees to collections? Seems excessive for what, like a $100 charge?

That's the kind of thing I'm worried about! I don't mind paying what I owe, but it's weird they haven't contacted me at all. Maybe I should just call them before it gets worse. Thanks for sharing what happened to your friend - definitely don't want collections involvement.

Oh this is a great point I hadn't even considered! I do arrange installation through subcontractors for about 60% of my projects. Would that still count as me providing installation services even though I'm subcontracting it out? Or does it matter that I'm including it as one bill to the client?

Generally what matters is how you present it to the client. If you're billing the client for a single transaction that includes both products and installation (even if subcontracted), most states will look at the entire transaction as a whole when determining tax treatment. If you separately state the charges on the invoice, some states will allow you to collect tax only on the product portion. But this varies dramatically by state. In some states like California, even separated charges might be considered part of a "bundled transaction" if they're part of the same project.

Yep, Colorado is especially bad with this! Almost 100 different local tax jurisdictions, many with their own rules. Louisiana is another nightmare state for local taxes. That's why I ended up using a sales tax compliance service rather than trying to figure it all out myself.

How do you track this yourself? My syndicator doesn't provide any details beyond the K-1 and when I asked about my carryover basis after our 1031, they just said "talk to your CPA." But my CPA wants documentation from THEM about how they calculated everything.

You need to maintain your own parallel records. Start with your original capital contribution, then add income reported on K-1s each year and subtract losses and distributions. This is your "outside basis" tracking. When the 1031 exchange happens, this basis should transfer to your interest in the new property, with adjustments if there was any boot or mortgage relief that triggered gain recognition. If your syndicator won't provide the calculations, you can derive them by comparing the final K-1 from the old partnership with the initial K-1 from the new one. The capital account sections should show how your investment transferred.

California is notorious for this. They consider it a sale if property leaves CA, even if it qualifies for 1031 treatment federally. Had the same issue when our syndication sold CA property and bought in Arizona. We all had to file nonresident CA returns and pay tax on the gain.
