This is really helpful! How did you calculate the value of housing and food to determine that you provided more than half her support? I'm trying to figure out how to quantify that properly.

For housing, I used the fair rental value of the room she stayed in (looked at comparable rooms for rent in our area) plus a percentage of utilities based on our household size. For food, I tracked grocery expenses for a couple months and calculated her portion based on that. I also included car insurance since we added her to our policy, cell phone costs since she was on our family plan, and medical expenses we covered. For her part of the support equation, I included her earnings from her part-time job, scholarships that covered room and board (not tuition), and any other financial help she received. The IRS has a worksheet in Publication 501 that helps with this calculation. The key is being able to show that your contribution exceeded 50% of her total support from all sources. In our case, the housing value alone was significant enough to clearly demonstrate we provided most of her support.

On TurboTax you should select "Other" when it asks for the relationship. Then when it asks if this person lived with you all year, select "Yes" (assuming they did, or if they were away at college but your home was their main residence). There's also a section where it will ask you to verify that you provided more than half their support.

Oh crap, I had no idea there was a 3-year deadline on refunds! That's really good to know. Do you think we should use a tax service like Jackson Hewitt at this point or just try to do it ourselves with tax software?

For a simple tax situation, tax software should work fine and save you money compared to Jackson Hewitt. Something like TurboTax or FreeTaxUSA can handle late filings easily. If her taxes are more complicated (self-employment, multiple income sources, investments, etc.), then a professional service might be worth the cost. They sometimes catch deductions or credits you might miss on your own. But for basic W-2 income, the software should be more than adequate and much cheaper.

Exactly! IRS is the worst bank ever... they take your money all year and don't even pay interest when they owe you a refund, but they sure charge interest when you owe them 😑

What about medical expense deductions? My husband has a lot of medical costs but I don't. Does filing jointly or separately matter for that?

Medical expense deductions are definitely impacted by filing status. For 2025, you can only deduct medical expenses that exceed 7.5% of your adjusted gross income (AGI). If you file separately, only your husband's medical expenses and AGI would be considered for his return. Here's a simple example: If your husband's AGI is $40,000 with $10,000 in medical expenses, and yours is $80,000 with minimal medical expenses, filing separately would let him deduct anything over $3,000 (7.5% of $40,000). So he could deduct $7,000. But filing jointly with a combined AGI of $120,000 means you'd only deduct expenses over $9,000 (7.5% of $120,000), reducing your deduction to just $1,000. In cases with large medical expenses, running calculations both ways is definitely worth it.

I've used FreeTaxUSA for the last few years - it's free for federal and like $15 for state. It handles all the married filing jointly stuff perfectly and lets you compare filing jointly vs separately to see which saves more. WAY cheaper than TurboTax and does basically everything the paid version does.

Do you know where I can find info about tax treaties? My in-laws are from India and I've wondered about this too.

You can find tax treaties on the IRS website - search for "United States Income Tax Treaties A to Z" and you'll find a list of all countries with treaties. For more detailed information, look for IRS Publication 901 (U.S. Tax Treaties). For India specifically, there is a tax treaty, but dependency rules are complex. The treaty mainly covers things like double taxation of income, but personal exemptions and dependent status are usually determined by the regular IRS rules I mentioned earlier.

Good point! I think the substantial presence test is 183 days (about 6 months) in a calendar year, so at 8 months she'd likely meet that. Would that make her ineligible as a dependent?

Thanks for the notebook tip - that's a great idea! I'll definitely start doing that. But what's this Section 1244 thing you mentioned? Is that something that would apply to my situation with just selling stuff online as a side thing?

I misspoke about Section 1244 - that's actually for losses on small business stock and wouldn't apply here. What I meant was that resellers can use the "Cost of Goods Sold" section on Schedule C to account for your inventory costs. The notebook method works great for casual sellers. I recommend categorizing items by type and condition, which helps establish a pattern. For example, "vintage t-shirts - good condition - $3-5 each" or "collectible figurines - mint condition - $10-15 each." This creates a reasonable framework for your estimates. Starting this practice now will make next year's taxes much easier, and having some documentation is always better than none.

TurboTax works ok for this but isn't great. It asks for cost of goods sold as a total number rather than helping you itemize. I found FreeTaxUSA actually handled my small eBay business better and asked more relevant questions about inventory and costs. Plus it's way cheaper.

I used TurboTax last year for my Etsy 1099-K. It was decent but I had to manually create my own spreadsheet for tracking cost of goods sold. It doesn't really help with estimating costs when you don't have receipts - you just enter your total estimate. If you're worried about documentation, you might want something more specialized or at least create your own tracking system alongside TurboTax.
