If you are a US person for tax purposes, you are required to report your foreign earned income and foreign financial assets if they have an aggregate balance higher than 10k at any time during the year.
If you have low income and low foreign financial assets, you may just be required to file a 1040 tax return. Many online services are cheap.
I’m not sure it would be prudent to recommend a do-it-yourself solution for complicated international tax reporting, but everybody has different needs.
