Thanks for this perspective! I definitely won't go back to H&R Block after that experience. Do you have any tips on finding a good CPA who knows how to handle these interstate moves and stock issues? Is there anything specific I should look for or ask when I'm interviewing them?

Look for a CPA who specializes in individual taxes rather than business taxes. Ask specifically about their experience with interstate moves and stock compensation (RSUs, options, etc). A good question is "how would you handle allocation of income between California and Oregon for a mid-year move?" Also ask about their approach to organizing those old 401ks - a good tax professional thinks beyond just this year's return. Check Google reviews, but also ask for referrals from colleagues in similar situations. Since you work for a large company, there might be others who've dealt with the same stock and relocation issues who can recommend someone.

I'll second FreeTaxUSA. It handled my interstate move and stock sales for $15 (for the state return). Federal filing is completely free regardless of complexity. TurboTax would have charged me $120+ for the same forms.

Thanks for confirming! I felt like I was taking a risk trying a less-known software but it worked perfectly. The interface isn't as pretty as TurboTax but it asks all the right questions and handles the complex scenarios at a fraction of the cost.

How exactly did you format your response? Did you use any specific IRS forms or just write a letter explaining the situation?

I wrote a formal letter that referenced the notice number and my tax ID at the top. I didn't use a specific IRS form, but made sure my letter was very clear and organized. I started with a direct statement: "I am writing to request abatement of the substantial understatement penalty because all income was properly reported on my original return." Then I included a table showing exactly where each item appeared on my return with line numbers and amounts. I attached highlighted copies of both my filed return and the 1099 forms, with the relevant numbers circled. I find that making it super easy for them to see the evidence increases your chances of success. Don't make them hunt for information or they might just deny your request due to lack of clear documentation.

Most tax software doesn't have great features for handling notices after filing. TurboTax has an "audit support" feature but it's pretty basic - mostly just gives you general guidance. H&R Block offers actual representation if you pay for their Peace of Mind extended service, but that's something you have to purchase when you file, not after you get a notice.

Yes, S-Corps are eligible for the 20% Qualified Business Income deduction. The same income thresholds apply ($170,050 for single filers and $340,100 for joint filers in 2025). Above those thresholds, limitations based on W-2 wages and qualified property start to phase in. Actually, this is where S-Corps can have an advantage over sole props for high earners. Since you're paying yourself a W-2 salary, that can help you qualify for larger QBI deductions if you're over the income threshold. It's a bit complicated but basically your W-2 wages to yourself can help satisfy the wage limitation tests.

Thanks for mentioning this! What exactly are the Excess Business Loss limits for 2025? I've been so focused on the passive vs non-passive issue that I totally overlooked this potential limitation.

For 2025, the Excess Business Loss limitation is $300,000 for single filers and $600,000 for joint filers. This means if your total business losses exceed your business income by more than these thresholds, the excess gets carried forward to future years. For most people with a single vacation rental property, this limit isn't an issue. But if you have multiple properties or other business losses, it could come into play. The At-Risk Rules are potentially more relevant in your case - they limit your deductible losses to the amount you have "at risk" in the activity, which typically includes your cash investment, the portion of loans you're personally liable for, and certain qualified non-recourse financing.

Totally agree! I feel like half of tax law is hidden in obscure regulations that normal people would never find. It seems like they make it intentionally complicated.

Thanks for the suggestion! My health insurance premium did actually increase slightly during this period, but the pretax deduction amount seems correct. I'll definitely double-check my state withholding though - I hadn't even thought to look at that separately! I'm in Minnesota, and now that you mention it, the state withholding does look a bit different on the new paystubs compared to federal. I'll compare the percentages to make sure everything adds up.

This is good advice. I work in HR and I can tell you we WANT to know about these issues. Sometimes during system migrations, default settings get applied instead of employee-specific ones. We can't fix what we don't know about!
