Don't forget the deadline to establish a Solo 401k is December 31 of the tax year, even though you can actually fund it later (employee contributions by tax filing, employer contributions by business tax deadline)! I missed this subtlety last year and lost out on significant tax savings. Also, for the record, my CPA confirmed that with a partnership LLC, both spouses can have separate Solo 401ks as long as they're both partners in the business, but you need to be careful with the specific plan documents.

This is a complex situation that requires careful planning! I've been through something similar with my spouse and our consulting business. One key point that hasn't been fully addressed: when you have a partnership LLC, the income flows through to you as distributive shares reported on Schedule K-1, which is treated as self-employment income for retirement contribution purposes. This is different from W-2 wages or 1099 consulting income in how the contribution limits are calculated. For your husband's situation specifically - since he already maxes out his employee contribution at his day job, he can only make employer contributions through the LLC based on his share of the partnership's net earnings from self-employment. The 20% calculation applies to his net earnings after the self-employment tax deduction. Also worth noting: make sure your partnership agreement clearly defines each partner's role and compensation if you're both setting up Solo 401ks. The IRS will want to see that the contributions are reasonable based on actual services provided to the business. I'd strongly recommend getting a fee-only financial advisor who specializes in small business retirement planning to review your specific numbers before making final decisions. The interaction between partnership income, outside consulting, and existing employer plans can get tricky fast.

Has anyone used TurboSelf-Employed for this kind of situation? I'm trying to figure out the easiest way to file with all these business expenses.

One thing to keep in mind is that since you're dealing with expensive camera equipment, you might want to look into Section 179 deduction vs. depreciation. For 2024, you can deduct up to $1,220,000 worth of qualifying business equipment in the year you purchase it instead of depreciating it over several years. This could be really beneficial for your lenses and tripod since they're probably under that threshold. Also, make sure you can prove the business use percentage if you ever use that equipment for personal photography too. The IRS will want to see that you're only deducting the portion actually used for your paid gigs. Keep a log of when you use the equipment for business vs. personal use - it'll save you headaches if you ever get audited. Your $800 in income definitely qualifies this as a business activity, so you're good there. Just make sure to report everything properly on Schedule C.

The IRS also has a tool on their website where you can look up your advance Child Tax Credit payments if you can't find Letter 6419. Just go to IRS.gov and search for "Child Tax Credit Update Portal" - you can log in and see exactly how much you received in advance payments throughout the year. This is super important to get right because if you enter the wrong amount on Schedule 8812, it'll throw off your entire refund calculation. I learned this the hard way when I accidentally used the wrong number and ended up owing money when I should have gotten a refund!

I had this exact same confusion when I was doing my taxes! The key thing to remember is that Schedule 8812 is designed to work in stages. First it calculates your total eligible Child Tax Credit for the year (which is what you're seeing on line 14i), then it accounts for any advance payments you already received. So that $9,400 on line 14i isn't your final refund amount - it's just showing that based on your two qualifying children, you're eligible for that total credit. The form then subtracts your $3,600 in advance payments on line 14j to show your remaining credit. Make sure you have your Letter 6419 handy (or check the IRS Child Tax Credit Update Portal online) to get the exact advance payment amount. Getting that number wrong will definitely throw off your calculation. Once you enter the correct advance payment amount and complete the rest of the form, you should see your actual remaining credit amount, which should be much closer to what you were expecting.

Has anyone dealt with this by sending a letter through certified mail? I'm in a similar situation and wondering if regular mail is good enough or if I should spend the extra money on certified mail with return receipt.

I went through almost the exact same thing last year! The IRS penalty notice made no sense since I had clear proof of payment before the deadline. Here's what I learned from my experience: First, get your account transcript from the IRS website (irs.gov) - it's free and shows exactly how they've recorded your payments. In my case, the transcript revealed that my payment was applied to the wrong tax year due to a data entry error on their end. Second, gather ALL your payment documentation - bank statements, confirmation numbers, screenshots from your tax software, anything that shows the payment date and amount. The IRS will need this to correct their records. Third, respond to the notice in writing with copies of all your proof. I sent mine certified mail with return receipt (costs about $7 but gives you proof they received it). In my letter, I requested penalty abatement under "reasonable cause" since I had paid on time and it was their processing error. The whole process took about 6 weeks, but they completely removed the penalty and sent me a letter confirming the correction. Don't just ignore it hoping it goes away - these penalties can grow with interest if not addressed promptly. The frustrating part is that these processing errors happen more often than the IRS likes to admit, especially during busy filing season. But they will fix it once you provide the documentation.

Can someone explain if there's any difference in how Form 2555 should be filled out using TurboTax vs. H&R Block? I've been using TurboTax but it seems to be giving me weird results for my Housing Exclusion when I enter my Singapore housing expenses. I'm wondering if H&R Block handles Form 2555 better?

I've been through a similar situation with Form 2555 while working in South Korea, and I can confirm that TurboTax's interface for foreign income exclusions can be frustrating. Based on your circumstances, here are a few additional considerations: Since you left Japan on December 4th and your assignment was confirmed indefinite on October 18th, you're correct to only include the post-October 18th amounts for taxable fringe benefits. However, double-check that your 297 days calculation is accurate - make sure you're counting complete 24-hour periods outside the US, not partial days. For Line 21c (the rental car), if the vehicle was available for both business and personal use, you should include the full amount after October 18th ($1,700) as taxable income. The IRS generally treats employer-provided vehicles as taxable fringe benefits when the assignment exceeds one year. One thing I'd recommend: consider filing Form 2555 by paper rather than through TurboTax if the software keeps giving you strange results. The IRS processors are quite familiar with these forms, and sometimes the manual approach is more straightforward than fighting with software that doesn't handle complex expat situations well. Also, make sure you have documentation from your employer about the exact date your assignment status changed to indefinite. This will be crucial if the IRS has questions about your fringe benefit calculations.
