My wife's parents passed away and left her one condos and one commercial property in Taiwan. Both were fully paid. 100% ownership. Taxes were paid in Taiwan for both. This was in 2016. The commercial property had a tenant and is the tenant is still there. The condo has since been rented and has a current tenant.
I'm now filing 2023 taxes. What forms or process do I need to take to account for any income received for these two properties? How far back do I need to report? I see that I can only amend my taxes for the past 3 years.
