Get your taxes done using TurboTax

@pk, thank you so much for your reply, very helpful. I had intended to purchase TurboTax on Amazon, but you have to be physically present in the US to purchase and download through them - or use a vpn that makes it seem like you’re located in the States. I ended up purchasing directly from TurboTax and was able to download and use the software, no problems. I used a US based credit card, did not even try my foreign based one. I plan on keeping my US account and any refunds or payments will go through it.
I haven’t submitted my returns yet, but I did change my address to Ireland in the forms, which I think I need to do to access the tax treaty between the two countries that prevents double taxation - could be wrong, as 2025 was my first year living outside the US. Thank you again for your help!
