This thread has been incredibly helpful! I've been making estimated tax payments for years but never fully understood the safe harbor calculation. The key insight that it's based on Line 24 (total tax AFTER credits) rather than before credits makes a huge difference in my situation. I have substantial credits from solar panels and energy-efficient home improvements, so my Line 24 was significantly lower than my pre-credit tax amount. I've been overestimating my safe harbor requirement and essentially giving the government an interest-free loan. For anyone else reading this - definitely make sure you're using the right line from your 1040. It's Line 24 "Total Tax" after all credits have been applied. Then apply either 100% or 110% depending on whether your AGI was above or below $150k. Simple once you know which number to use!

This discussion has been incredibly enlightening! I'm a newcomer to the community and have been struggling with estimated tax payments for my freelance work. Reading through all these explanations about using Line 24 (total tax after credits) for the safe harbor calculation has saved me from making a costly mistake. I was about to base my calculation on my pre-credit tax amount, which would have resulted in significant overpayment. The distinction between 100% vs 110% based on the $150k AGI threshold is also crystal clear now. One follow-up question for the group: if you're self-employed and your income varies dramatically month to month, is it better to make equal quarterly payments based on the safe harbor amount, or should you try to match your payments to your actual income flow throughout the year? I've heard the IRS prefers even payments, but I'm curious about practical experiences with uneven payment schedules. Thanks to everyone who shared their knowledge and experiences - this community is incredibly valuable for navigating these complex tax situations!

I had this exact same problem last month! The trick that finally worked for me was looking for a small "More Details" or "Advanced" link on the investment entry screen. In H&R Block, after you enter the basic 1099-B information, there's usually a tiny link (easy to miss) that expands the form to show additional fields including the acquisition date. Also, if you're entering multiple sales of the same stock purchased at different times, H&R Block sometimes requires you to enter each lot separately with its own acquisition date. This might be why the error keeps appearing - the software is expecting individual entries for each purchase date rather than a single combined entry. Try scrolling all the way to the bottom of the investment entry screen and look for any "Show Additional Fields" or similar options. The acquisition date field is often hidden in these expanded sections.

I've been following this thread because I had the exact same H&R Block error message last week. What finally worked for me was a combination of the solutions mentioned here. First, I found that "More Details" link that Liam mentioned - it was hiding at the bottom of the screen and I had missed it completely. But even after finding the acquisition date field, I was still getting errors because I had some really old stocks where I honestly couldn't remember the exact purchase dates. That's when Eleanor's advice about calling the IRS became really helpful. I didn't use the Claimyr service, but I did eventually get through to an IRS agent (after waiting about 90 minutes on hold). The agent confirmed that for old stocks where you don't have exact dates, you can use January 1st of the year you know you purchased them, or if you have records showing it was held for more than a year, you can use the "date acquired not available" option that Kai mentioned. The key thing the IRS agent told me was that as long as you're correctly categorizing the gain as short-term vs long-term, the exact acquisition date isn't as critical as H&R Block makes it seem. The software is just being overly cautious about requiring that field. For anyone still stuck: try the "More Details" approach first, then use January 1st of the purchase year if you're unsure of exact dates, and don't be afraid to use the "date not available" checkbox if your stocks were clearly held long-term.

I've been dealing with this same ID.me nightmare for the past month! What finally broke me out of the loop was using a completely fresh approach: I borrowed my neighbor's tablet, connected it to the coffee shop wifi down the street, and created a brand new ID.me account with my old college email address. The key was using a phone number I'd never used with ID.me before (my work cell). The whole verification process went smoothly since their system didn't have any failed attempt flags on that combination. Took about 20 minutes total and I finally got access to my transcripts. Sometimes you just have to outsmart their security system by starting completely clean. Also learned that if you've failed too many times from the same device/network combo, you're basically blacklisted for a while. Hope this helps someone else avoid the weeks of frustration I went through!

Ugh, I feel your pain! I went through this exact same ID.me disaster about 6 months ago and it nearly drove me insane. What finally worked for me was the "nuclear option" - I had to use a completely different device (borrowed my brother's computer), connect through a different network (used my phone's mobile hotspot), and most importantly, use a phone number that I had NEVER used with ID.me before (ended up using my mom's cell phone for the verification codes). The whole thing took maybe 30 minutes once I stopped trying to fix my "flagged" setup. It's ridiculous that we have to jump through these hoops just to see our own tax information, but ID.me apparently blacklists your device/network combo after too many failed attempts. The system is totally broken but this workaround should get you unstuck. Also, make sure you're not using any browser extensions or VPN when you try - those can interfere with their verification process. Good luck!

Has anyone noticed that TurboTax seems especially glitchy with child tax credits this year? I've had similar issues where it zeroed out my credits, then they reappeared when I went back and re-entered the exact same information!

I'm glad you were able to resolve this issue! Your experience highlights a really important point about tax software - sometimes the smallest input errors can have huge impacts on your return. For future reference, one thing that might help others avoid this is to always do a final review of the "Review Your Return" or summary section before filing. Most tax software will show you a breakdown of all your credits and deductions there, which makes it easier to spot when something looks wrong (like $0 child tax credits when you clearly have qualifying children). Also, if anyone else runs into similar issues, try using the "Forms Mode" or "Detailed View" in your tax software if available. Sometimes the interview-style questions can lead to these kinds of dropdown errors, but looking at the actual tax forms can make it clearer what information is being entered where. Thanks for sharing your solution - I'm sure this will help other parents who encounter the same problem!

For US-Australia tax treaty resources, I'd recommend starting with IRS Publication 597 (Information on the United States-Canada Income Tax Treaty) as a reference point, then look at the actual US-Australia tax treaty text on the IRS website under "Tax Treaties." The Australian Taxation Office also has guidance on their website about US tax obligations for Australian residents. A few practical tips as you get started: **Documentation to keep**: Australian tax returns, payment summaries, bank statements, and any records of taxes paid to Australia. You'll need these for Foreign Tax Credit calculations. **Timing**: US tax year runs January-December, while Australian tax year is July-June. This can create some complexity in matching up income and tax payments between the two systems. **Professional help**: Even if you use software or AI tools, consider getting professional advice for your first filing to establish the correct approach. Many expat tax specialists offer consultations to review your specific situation. **FBAR reminder**: Don't forget that if your Australian accounts (including savings, super, investment accounts) total more than $10,000 USD at any point during the year, you need to file FinCEN Form 114 separately from your tax return. The most important thing is not to let perfect be the enemy of good - start with basic compliance and refine your approach over time. You're asking the right questions at the right age!

As someone who went through this exact situation, I can't stress enough how important it is to get proper guidance early! I'm a dual Australian-US citizen who waited until I was 25 to sort out my US tax obligations, and I really wish I had started at 18 like you're doing. The main thing to understand is that while the compliance requirements might seem overwhelming, the actual tax burden is usually minimal or zero thanks to the Foreign Tax Credit and Foreign Earned Income Exclusion. Australia's tax rates are generally higher than US rates, so you'll typically get full credit for taxes paid here. Here's my practical advice: - Start filing US returns even if you don't owe anything - it establishes your compliance history - Keep detailed records of ALL Australian tax documents and payments - Don't forget about FBAR if your Australian accounts exceed $10,000 USD - Consider using the Streamlined Filing Compliance Procedures if you haven't been filing The peace of mind from being compliant is worth the annual hassle. Plus, having both passports has been incredibly valuable for travel, work opportunities, and just keeping your options open. I've worked in both countries and the flexibility has been amazing. Your parents mean well, but renouncing is irreversible and unnecessary for most people in our situation. The annual filing becomes routine once you establish the process!
