That's a good point. I just checked and his withholding from the first job was about 8.5% of his gross income. That does seem a bit low now that you mention it. Could that be contributing to the problem as well?

Yes, 8.5% is definitely on the low side for federal withholding. For someone making around $38,000, you'd typically expect to see closer to 10-12% withheld for federal taxes, assuming standard deduction and no special circumstances. This confirms that both employers were under-withholding. The first wasn't withholding quite enough, and then the second one withheld almost nothing because of the single paycheck issue. When combined, this created the unexpected tax bill. For 2025, he should definitely update his W-4 with his current employer to request additional withholding - maybe an extra $20-30 per paycheck to make up for the shortfall.

This is so helpful! My parents have been dealing with the exact same issue and I couldn't figure out why. Dad works at two different places and every year they owe a bit even though both jobs withhold taxes. Now I understand it's because neither employer knows about the other income.

Thank you! I tried going back through the Form 8863 section specifically and I think I found the issue. There was a checkbox asking if my expenses were for "qualified education expenses" that I had missed. After checking that and going through that section again, it's now showing I owe $0 instead of $817! I understand now about the non-refundable part. I wasn't expecting to get money back, just wanted to not owe anything. This is such a relief!

Great to hear you got it figured out! Yes, that checkbox is crucial - it's easy to miss but makes all the difference. The tax software can't apply the credit if it doesn't know your expenses qualify. That's exactly right about non-refundable credits - they can bring your tax liability down to zero but no further. For future reference, if you expect to have tax liability again next year, you might want to consider making estimated tax payments throughout the year since you're self-employed. It can help avoid a surprise bill come tax time, even with credits applied.

This is a good point. You can check if your school is eligible by looking up its Federal School Code on the FAFSA website. Almost all accredited universities and colleges qualify, but some vocational programs or non-degree programs might not.

I hadn't even thought about Section 179 for the yard improvements! Would that be instead of including the square footage in my home office calculation, or could I possibly do both? The improvements cost about $4,800 total.

You generally can't double-dip by claiming the same expenses two different ways. The home office deduction would let you deduct a percentage of all household expenses including utilities, insurance, mortgage interest, etc. based on square footage used for business. If you instead use Section 179 for the improvements, you could potentially deduct the full $4,800 immediately rather than depreciating it over time, but you wouldn't include that outdoor space in your home office square footage calculation. It often comes down to which method gives you the better deduction in your specific situation.

The simplified option is definitely easier but it's generally not great for this situation. It's capped at 300 sq ft which is probably less than your combined indoor office and outdoor dog area. Plus, as you mentioned, there's no provision for including outdoor space. I'd stick with the regular Form 8829 if you want to include that yard space.

Thanks for confirming my suspicion. The simplified method seems too limiting for my situation. I'll go with Form 8829 so I can properly document all the space I'm using for business.

The "pennies on the dollar" marketing is mostly hype, but Offers in Compromise are legitimate. The IRS accepts about 40% of OICs submitted, but they use a very specific formula: they look at your assets, income, and future earning potential to determine what they call your "reasonable collection potential." It's not about what percentage of the debt you're offering, but whether your offer matches what the IRS calculates they could reasonably collect from you over the remaining collection statute (usually 10 years from assessment). Some people qualify for significant reductions, while others might not qualify at all if they have substantial equity in assets or high income. The key to success is having the OIC properly prepared with thorough documentation of your financial situation. The application (Form 656) requires detailed financial disclosure, and the IRS verifies everything.

Yes, they're definitely related. Banks are required to get your TIN (your SSN in this case) for tax reporting purposes. The backup withholding you heard about happens if you don't provide a TIN or if the IRS notifies the bank that you provided an incorrect TIN.

Which tax software do you recommend that's actually affordable? I used FreeTaxUSA last year but wasn't super impressed with how they handled my 1099 income.
