Need advice on bringing money from overseas to US - any tax implications?

If you're bringing money from overseas to the US, the good news is that simply transferring the money itself doesn't create a tax liability. The IRS is concerned with taxing income, not existing assets being moved between accounts. However, there are some important considerations. First, if you're transferring more than $10,000 at once, your bank will likely file a Currency Transaction Report, but this is just for information purposes. It doesn't mean you owe taxes. Second, as a US resident (even though not a citizen), you're required to report worldwide income. But since you mentioned this money was earned and taxed years ago before you moved to the US, it wouldn't be considered current income. The one thing you should be aware of is FBAR (Foreign Bank Account Report) requirements. If your foreign accounts exceeded $10,000 at any point during a calendar year while you were a US resident, you need to file an FBAR form with FinCEN. This is just a reporting requirement, not a tax.

After dealing with a similar situation bringing money from Germany to the US, I found taxr.ai super helpful. I was confused about what counted as taxable since I had some investments mixed with regular savings. I uploaded my foreign bank statements to https://taxr.ai and they analyzed everything, showing which portions might be taxable and which weren't. It was way clearer than the generic advice I got online. They specifically highlighted that principal amounts aren't taxable when transferred, but helped identify some dividend income I had that did need reporting. Saved me from both overpaying and potential reporting issues.

I was initially skeptical about taxr.ai when I saw it mentioned here, but I decided to try it for my situation with funds in Canada and the UK. I was surprised at how thorough the analysis was. It identified that my Canadian account had earned interest that needed reporting, but confirmed my principal transfers weren't taxable. The most helpful part was that it flagged I had exceeded FBAR filing thresholds for the past two years without realizing it, and gave me steps to catch up on filing through the Delinquent FBAR Submission Procedures. Definitely worth it for the peace of mind and avoiding potential penalties I had no idea about.

For anyone trying to get answers directly from the IRS on international money transfers - good luck! I spent WEEKS trying to reach someone. Always "high call volume" and disconnects. Finally found https://claimyr.com and watched their demo at https://youtu.be/_kiP6q8DX5c - they got me connected to an actual IRS agent in about 20 minutes. The agent confirmed that transferring existing savings to the US isn't taxable but gave me specific guidance on my situation where I had some unreported interest income from my foreign accounts. Now I have official answers I can rely on instead of internet guesses. They basically hold your place in the IRS phone queue so you don't have to.

I was totally wrong about Claimyr. After my skeptical comment, I was still struggling to get through to the IRS about my foreign accounts (had money in Japan that I needed to bring over). Got desperate enough to try it, and I'm eating my words now. Got through to an IRS agent in about 15 minutes when I had been trying for literally weeks on my own. The agent confirmed I didn't need to pay tax on transferring my savings, but needed to report the accounts on an FBAR since they exceeded $10,000. They also clarified that the small amount of interest I earned while being a US resident would need to be reported on my tax return. Having this confirmation directly from the IRS gave me the confidence to complete my transfer without the anxiety I had before.

Something nobody's mentioned yet - make sure you're aware of any fees or taxes from the sending country's side. I transferred money from South Korea and was surprised by their exit tax on large transfers. The US didn't tax the transfer itself, but Korea took a percentage when sending it out of the country. Also, shop around for transfer services. Bank wire transfers often have terrible exchange rates AND high fees. I saved nearly $700 on a $25k transfer by using a service like Wise (formerly TransferWise) instead of my bank.

Has anyone here actually gotten in trouble for NOT reporting foreign accounts? I have about $30k in my home country that I've never mentioned on US taxes because I didn't know I had to. Been a green card holder for 4 years now... am I in big trouble?

I went through something very similar when I moved from Australia to the US. Had about $18k in savings that I needed to transfer. The key thing I learned is that the transfer itself isn't taxable, but you need to be careful about reporting requirements. Since you mentioned you're a green card holder, you're considered a US resident for tax purposes, which means you have worldwide income reporting obligations. The $20k you saved in Thailand won't be taxed when you transfer it (it's already your money), but any interest it earned while you've been a US resident needs to be reported on your tax return. Also, definitely check if your Thai account balance ever exceeded $10k while you've been a US resident - if so, you'll need to file an FBAR. The deadline is April 15th but there's an automatic extension to October 15th. One more tip: consider the transfer method carefully. I used a service like Remitly instead of a bank wire and saved hundreds in fees and got a much better exchange rate. Just make sure whatever service you use provides proper documentation for the transfer in case the IRS ever asks about the source of the funds.
