Make sure you're not confusing margin interest with your line of credit interest! They're treated differently. Margin interest from a brokerage account is investment interest, but your line of credit interest is only deductible as investment interest if you can directly trace the funds to investment purposes.

One thing I'd add that hasn't been mentioned yet - if you're using the line of credit for rental property down payments, be careful about when you start deducting that interest. The IRS generally requires that rental property be "in service" (actively generating rental income or available for rent) before you can deduct related expenses on Schedule E. So if you use part of your credit line for a down payment in January but don't get the property ready for tenants until June, you might need to capitalize that interest as part of the property's basis rather than deduct it immediately. Once the property is in service, then future interest payments related to that portion become deductible rental expenses. This timing issue caught me off guard on my first rental property purchase. I'd recommend consulting with a tax professional if you have multiple properties at different stages, as the rules can get complex when you're juggling acquisition costs, improvements, and ongoing expenses.

Has anyone noticed if either option is better for catching audit red flags? My brother got audited last year using downloaded software and now I'm paranoid.

I've been wrestling with this exact same question! After reading through all these responses, I think I'm leaning toward online versions now. The point about frequent security updates really resonates with me - I'll admit I'm not great about manually updating software on my computer, so having that happen automatically in the cloud seems safer. One thing that's helping me feel better about the security aspect is that these companies are handling millions of tax returns, so they have a huge incentive to keep their systems secure. A data breach would literally destroy their business overnight. Meanwhile, my home computer security is only as good as my own tech skills, which honestly aren't that impressive. The convenience factor is also huge - being able to access my returns from anywhere and having automatic backups means I don't have to worry about losing everything if my computer crashes. Thanks everyone for the thoughtful discussion - this has been really helpful in making my decision!

I'm so confused about all this Premium Tax Credit stuff. This is my first year dealing with Marketplace insurance. So if my mom claimed me on her insurance for part of the year, do I need to fill out this 8962 form too even if I'm not claiming any of the credit? I didn't get a 1095-A form myself.

Just went through this exact same situation last month! The IRS letter can be scary but it's actually a pretty straightforward fix. Like others mentioned, you need to complete Part II of Form 8962 showing all the monthly calculations with your 0% allocation - even though it results in zeros, the IRS needs to see the work. Here's what worked for me: I filled out a new Form 8962 with "CORRECTED" written at the top, completed the monthly table in Part II showing the premium amounts from the 1095-A multiplied by 0%, attached a copy of the 1095-A that showed my name, and included a brief letter explaining the 100%/0% allocation agreement with the other taxpayer (including their name and last 4 of SSN). Sent it certified mail and got a letter back in about 6 weeks saying the matter was resolved. The key is showing the IRS that you properly reconciled with the 1095-A information they have on file, even with a 0% allocation.

lol irs making everything complicated as usual 🤡

Just went through this exact situation last year! Your 18-year-old definitely qualifies as a dependent since they're still in high school. The key things are: they lived with you more than half the year (check!), you provide more than half their support (sounds like it), and they're under 19 OR a full-time student under 24. High school senior absolutely counts as a student. You're totally fine to claim all 4 kids!

I'm still confused about one thing - if I can't create an online account because of the verification issues (I don't have a credit card or loan), is there any other way to get my transcripts quickly? Will calling the IRS help? And once I get the transcript, how do I know which codes to look for specifically for my amended return status?

If you can't create an online account due to verification issues, you have a few alternatives! You can request transcripts by mail using Form 4506-T (takes 5-10 business days), or call the automated transcript line at 1-800-908-9946. For phone requests, you'll need your SSN, date of birth, and filing status. For amended returns specifically, focus on these key codes on your Account Transcript: TC 971 (amended return received), TC 570 (account frozen for review - this is normal initially), TC 290/291 (adjustment made), and TC 846 (refund issued). The sequence typically goes 971 → 570 → 290 → 846. If you see 570 without movement for over 4-6 weeks, that might indicate additional review is needed. The "Where's My Amended Return" tool online can also give you basic status updates without needing full transcript access, though it's less detailed than the actual transcript codes.
