Anyone else notice the IRS rules for retirement accounts seem designed to be confusing? Some random thoughts that might help: 1) if u have a 401k at work, the ira deduction phases out at high incomes 2) if ur over the limits, backdoor roth is usually better than non-deductible trad ira 3) dont forget u can do both 401k AND ira in same year, just might not get trad ira deduction 4) also check if ur 401k has after-tax contributions with in-plan roth conversions... thats the "mega backdoor roth" and is awesome if available!!

Great question! I was in a similar situation last year and learned this the hard way. Since you're covered by a 401(k) at work and earning $210k, you won't be able to deduct traditional IRA contributions at all - the deduction phases out completely for single filers around $90k and married filing jointly around $136k when you have workplace retirement coverage. Your strategy of splitting $17k traditional 401(k) + $7k traditional IRA wouldn't give you the full $24k in deductions you're hoping for. The $7k IRA contribution would be non-deductible. Instead, consider these options: 1) Max out traditional 401(k) at $24k for full deduction 2) Split between traditional and Roth 401(k) for tax diversification 3) Do backdoor Roth IRA with that extra $7k (but watch out for pro-rata rule with your existing rollover IRA) The backdoor Roth might be tricky since you mentioned having a rollover IRA. You'd either need to roll that into your current 401(k) first (if allowed) or deal with pro-rata taxation on the conversion. Definitely worth running the numbers on different scenarios to see what works best for your situation!

Actually, the IRS absolutely does care about correct employer attribution! 😂 Their matching system isn't just checking total income - it's verifying each specific W-2 against what employers reported. Think of it like your credit report - having the right total but wrong accounts would still be a problem. The good news is that since the total income is correct, this is a relatively simple amendment. Your preparer should file Form 1040-X showing the correct employer for each income amount. Since this doesn't change your tax liability, it's more of an administrative correction than a substantive one.

I completely understand your concern, especially with this being your first tax season filing separately after your divorce. The employer mismatch absolutely needs to be corrected - the IRS matching system will flag this even though your total income is accurate. Here's what you should do: Contact your tax preparer immediately and request they file Form 1040-X at no cost to you (since this was their error). Make sure to bring both W-2s and clearly show which income should be attributed to which employer. The amendment process typically takes 16-20 weeks, but since you're not changing your tax liability, there shouldn't be any penalties. Given your post-divorce situation, having accurate employer documentation is especially important for any potential support calculations or financial verifications you might need later. Don't let this stress you out too much - it's a common preparer error that's easily fixable!

One thing nobody's mentioned yet - the timing might matter here too. Were these Incentive Stock Options (ISOs) or Non-qualified Stock Options (NSOs)? Because if they were ISOs and you didn't hold them long enough after exercise (at least 1 year from exercise and 2 years from grant), they get disqualified and treated as NSOs which changes the tax treatment.

I've seen this happen a lot with my clients. Most tax software lets you make this adjustment pretty easily. Which tax program are you using to file?

Everyone's talking about refunds, but the real question is: could you have paid less in total taxes? Look into maximizing pre-tax contributions next year. You only put $2500 in your 401k, but the limit is $22,500 for 2023 and $23,000 for 2024. Even increasing to 10% of your salary would make a big difference in your tax bill. Also consider an HSA if you have an eligible health plan - that's another pre-tax contribution that reduces your taxable income. Between those two things, you could potentially reduce your taxable income by $10k+ and save thousands in taxes.

This is a really common misconception! The key thing to understand is that your refund amount doesn't reflect how much you paid in taxes - it only shows how much you overpaid during the year through withholding. Breaking down your situation: out of that ~$20k deducted from your paycheck, about $13,800 went to taxes that aren't refundable (Social Security $4,100 + Medicare $1,000 + actual federal income tax liability of ~$6,550 + state taxes of ~$2,000 + $150 you still owe). The remaining $6,200 was federal withholding that exceeded what you actually owed, hence your $1,150 refund. Your effective tax rate is actually quite reasonable for your income level. The "problem" isn't that you're being overtaxed - it's that your withholding was fairly accurate to your actual tax liability, which is actually a good thing! Getting a huge refund means you gave the government an interest-free loan all year. If you want more money in your pocket, consider increasing your 401k contribution (you're only doing $2,500 of the $23,000 limit) rather than trying to get a bigger refund.

Has anyone looked into whether it's better to take distributions from your S-Corp and then fund a backdoor Roth vs setting up these more complex retirement plans? Especially if you expect to be in a higher tax bracket in retirement?

This thread has been incredibly helpful! I'm in a similar situation but with one additional wrinkle - I'm also contributing to a HSA through my W-2 job. Does that impact any of the S-Corp retirement plan contribution limits mentioned here? Also, for those who mentioned taxr.ai - did their analysis include HSA optimization as part of the overall retirement planning strategy? I'm trying to figure out if I should prioritize maxing my HSA first before setting up the Solo 401k, or if they work completely independently of each other. One more question - if I set up a Solo 401k through my S-Corp this year, can I still make catch-up contributions when I turn 50 next year, or do those limits get complicated when you have multiple 401k accounts?
