I had a similar situation with mixed income sources and was initially confused about my QBI calculation too. After reading through all these responses, I realize I should have done more research upfront about the SSTB vs non-SSTB distinction. For anyone else in this situation, I'd recommend documenting your income split from day one. I wish I had kept better records showing the time and effort I spend on different business activities. It would have made tax time much less stressful. One thing that helped me was creating a simple spreadsheet tracking which clients pay for consulting services versus which ones buy my software products. Even though some clients do both, I can clearly show the revenue breakdown and the different types of work involved. This kind of contemporaneous record-keeping seems like it would be valuable if the IRS ever had questions. The phase-out calculation is definitely more nuanced than I originally thought. Thanks to everyone who shared their experiences - it's really helpful to know I'm not the only one who found this confusing!

As someone who's been through QBI calculations for a mixed consulting/product business, I can confirm your software is likely correct! The phase-out rules are really complex when you have multiple income streams like yours. The key insight that helped me understand my situation was realizing that IT consulting is typically considered a Specified Service Trade or Business (SSTB) and subject to the $170,050-$220,050 phase-out range for 2024, but software product sales are generally NOT considered SSTB income. This means you can reasonably allocate your $178,000 between these two categories. For your consulting income portion, you'd face the gradual phase-out since you're in that range. But for your software sales portion, you'd get the full 20% QBI deduction with no income-based limitations. If a significant chunk of your $178,000 comes from software sales, this could easily explain why your deduction is higher than expected. The most important thing is having good documentation to support this split. Keep separate invoices, track time spent on each activity, and maintain records showing these are distinct business operations. I learned this the hard way when I realized my record-keeping wasn't as detailed as it should have been! Your $25,600 deduction sounds reasonable if you have a good mix of SSTB and non-SSTB income. The tax software likely made this allocation automatically based on how you categorized your revenue streams.

Has anyone tried checking the "Married filing separately" box on the W4 but still filing jointly on the actual tax return? My tax guy suggested this for my situation where my wife makes 3x what I make.

I went through this exact same situation last year! The multiple jobs worksheet can be brutal when there's a huge income gap like yours. Here's what worked for me: Instead of using the multiple jobs worksheet on your W-4, try this approach: Keep your W-4 simple (just check "Married filing jointly" and claim your standard withholding), then have your spouse add extra withholding on their W-4 using line 4(c). Since they make $350k, even a few hundred extra per paycheck won't hurt them as much as it's hurting your $45k paychecks. To estimate the right amount: Take last year's total tax liability, subtract what would normally be withheld from both your paychecks with standard withholding, and divide that difference by your spouse's number of pay periods. Add that amount to line 4(c) on their W-4. This way you keep most of your paycheck while still covering the extra tax burden from your combined high income. You can always fine-tune it once the IRS calculator comes back online, but this should give you immediate relief from having empty paychecks.

Has anyone dealt with a situation where they're a member of a multi-member LLC taxed as a partnership, but have different liability allocations for different LLC debts? I guarantee some loans but not others, and I'm not sure how to calculate my basis correctly.

This is a great discussion that highlights how confusing partnership basis can be! I've been dealing with similar issues with my LLC interest. One thing I learned from my CPA is that the software warnings are often overly cautious because they can't analyze the specific terms of your operating agreement. The reality is that many LLCs have hybrid structures where members might have limited liability for some debts but economic risk of loss for others. Your basis calculation needs to reflect your actual economic exposure, not just your legal classification as a "limited partner." I'd recommend getting a copy of your LLC's operating agreement and looking for any sections about guarantees, capital calls, or deficit restoration obligations. These provisions can significantly impact how partnership liabilities affect your outside basis, even if you're technically a limited member. Also, don't forget that if you've been understating your basis due to software limitations, you might be able to amend prior returns to claim losses that were previously suspended. The statute of limitations for claiming refunds is generally three years, so it's worth reviewing your last few returns if you think you've been missing out on legitimate loss deductions.

I'm wondering if something fishy is happening with your therapist's taxes. My wife is a private practice therapist, and she's REQUIRED to provide documentation of payments to clients. For cash payments, she gives a receipt at each session and provides year-end statements in January. The fact your therapist is charging extra for this basic business function suggests either extremely poor business practices or possibly tax evasion. Neither is good. If you continue with her, I'd strongly suggest switching to checks or electronic payments and getting receipts for EVERY payment going forward.

As someone who's navigated similar documentation challenges with healthcare providers, I'd recommend taking a two-pronged approach. First, create your own detailed payment log immediately using your calendar, bank withdrawal records, and any text/email communications about appointments. This shows good faith effort to maintain records. Second, send your therapist a formal written request (email is fine) stating that you need payment documentation for legitimate tax purposes. Offer to pay reasonable administrative costs if needed, but emphasize this is standard business practice. If she continues to resist, consider that this may indicate larger issues with her business practices. For future payments, absolutely switch to checks or electronic transfers that create automatic paper trails. You shouldn't have to chase down basic payment records from any professional service provider. The IRS accepts various forms of documentation for medical expenses, but having a clear paper trail makes everything much smoother during tax preparation and potential audits.

maybe a dumb q but does anyone know if vanguard's incentive offer for ira transfers counts as income? got $450 for moving my rollover and wondering if i'll owe taxes on that bonus

Great breakdown in the comments so far! Just want to add one more consideration for your partner's backdoor Roth situation. Even though she hasn't done any rollovers this year, she'll still need to watch out for the pro-rata rule if she has any existing pre-tax IRA balances. The rule applies per person, so your rollover activity won't affect her calculations, but any Traditional/SEP/SIMPLE IRAs in her name will. Also, regarding your question about people who do backdoor Roths annually - most don't worry about timing it around a specific date each year since conversions aren't subject to the once-per-12-month rollover rule. You can do a backdoor Roth in January every single year if you want. The key is just making sure you don't have other pre-tax IRA money mucking up the pro-rata calculation. One last tip: if you do decide to move your Rollover IRA into a current employer's 401(k) to clean up the pro-rata issue, make sure your plan accepts rollovers first. Not all employers allow incoming transfers.
