Quick heads up - something nobody mentioned yet is that if you go the Solo 401k route, once your account balance hits $250,000, you'll need to file Form 5500-SF annually. Not a huge deal but something to be aware of for future planning.

One thing I'd add that might be helpful - if your consulting income varies significantly year to year (like yours does between $55k-$105k), you might want to consider making quarterly estimated tax payments that include your retirement contributions. This helps with cash flow management and ensures you're not scrambling at year-end. Also, since you're already with Vanguard, their Solo 401(k) has really low fees and good investment options. When you call them, ask about their "Individual 401(k)" - that's what they call their Solo 401(k) product. They'll walk you through the whole process and can even help you figure out the optimal contribution strategy based on your projected income. One last tip: keep detailed records of all your business expenses from the consulting work. The more legitimate business expenses you can deduct, the higher your net profit will be, which means you can potentially contribute more to the retirement account (since it's based on that 25% of net self-employment income calculation).

I've been using QuickBooks for my online business, and they actually have a feature to help with inventory adjustments like this. If you're using QuickBooks or similar software, you might want to check if they have a specific process for handling inventory count corrections. In my case, I was able to make an inventory adjustment entry that clearly documented the reason for the change. This created a paper trail showing exactly what happened and when I discovered the error. My tax software then helped me address Line 35 appropriately with the correct wording.

I went through something very similar with my small retail business last year. One thing I'd add to the great advice already given here is to make sure you're prepared for potential follow-up questions if the IRS does review your return. In addition to the Line 35 explanation, I kept a simple spreadsheet showing the original count vs. corrected count for each affected item, along with the unit cost and total value difference. I also noted the date I discovered the error and what caused it (in my case, I had double-counted some items that were stored in two different locations). My CPA recommended keeping this documentation for at least 3 years in case of questions. She said having this level of detail ready actually reduces the chance of extended scrutiny because it shows you're being thorough and transparent about the correction. Also, since you mentioned you're behind on your inventory count - this might be a good time to implement a more systematic counting process for future years. I started doing quarterly spot checks on my highest-value items, which has helped me catch errors much earlier. Good luck with your filing!

Has anyone here actually been audited regarding prepaid expenses? My CPA is super conservative and basically refuses to let me prepay anything except trivial amounts. Says it's a "red flag" but I think he's being overly cautious.

Great question about prepaying expenses! I actually work as a tax preparer and see this situation all the time with small business clients. The key is understanding that legitimate prepayments are perfectly acceptable - it's not about gaming the system, it's about timing your cash flows strategically. One thing I'd add to the excellent advice already given: consider prepaying your quarterly estimated taxes for next year if you expect similar income levels. You can make your Q1 estimated payment in December and deduct it immediately, which can provide significant tax savings without any compliance risk. Also, don't overlook professional development expenses - conference fees, certification renewals, or training courses scheduled for early next year can often be prepaid in December. These are usually clear-cut deductions that auditors rarely question. Just make sure whatever you prepay represents a genuine business expense you would incur anyway. The IRS doesn't care about the timing strategy as long as the underlying expenses are legitimate and properly documented.

Just to add another data point - this EXACT issue is why I stopped using TurboTax for my foreign tax returns. I switched to TaxAct which actually lets you override the amount on line 19 without jumping through a million hoops.

I went through this exact same issue last year! The key thing to understand is that Form 1116 doesn't automatically force you to use all your foreign tax credits - you absolutely can elect to carry forward excess amounts. Here's what worked for me: On Form 1116 Part III, line 19 is where you enter the amount of foreign tax credit you want to claim for the current year. Most tax software defaults to the maximum allowable amount, but you can manually enter a lower amount if you want to preserve credits for future years when you might have higher tax liability. Since you mentioned having different categories (like passive income), make sure you're filling out separate Form 1116s for each category. The carryover election is made separately for each category. One tip - if your tax software won't let you override line 19, look for an "override" or "manual entry" option in the forms section. Every major tax software has this capability, though they sometimes hide it pretty well! If all else fails, you might need to file a paper return to have complete control over your foreign tax credit elections. Keep detailed records of your carryover amounts since they can be used for up to 10 years. Good luck with your return!

Has anyone used any of these online tax programs like TurboTax or H&R Block online? I've been thinking about just doing my taxes myself to avoid these kinds of issues with preparers, but I'm worried I'll miss deductions or make mistakes.

This is definitely not normal and I'd strongly advise against it. I'm a CPA and percentage-based fees tied to refund amounts are considered highly unethical in our profession. The National Association of Tax Professionals explicitly states that fees should be based on the complexity and time required for the work, not on the tax results. When a preparer's pay depends on maximizing your refund, they have a financial incentive to take aggressive positions that might not hold up under IRS scrutiny. I've seen clients get burned by this - they pay higher fees and then face audits because their preparer claimed questionable deductions to inflate the refund. A legitimate tax professional should charge a flat rate or hourly fee regardless of whether you owe money or get a refund. The fact that she's framing this as "aligning interests" is a red flag - a good preparer's interest should be preparing an accurate, compliant return, not maximizing your refund for their own benefit. I'd recommend shopping around for a new preparer who charges transparent, flat fees. Your $150 flat rate was actually quite reasonable for most returns.
