I was an international employee, that company was deducting money for retirement as per its international plan, I was not working in the US neither holding any green card or citizenship for the US. I moved to US, contributions stopped, I start paying income taxes from 2010 to 2022, I was hired by another company in 2023 and this company as expected closed my international account and sent the money (2003- 2010) contributions to my US checking .. is this money consider income I have to pay taxes ? Considering that it was generated before my time in the US and before I become US resident.
