I'm hoping I can get some simple guidance here on the the Streamlined Filing process for my twin daughters. Up to and including 2017 they were included in my own return as dependants - full supported living at home post university (yes, boomerang kids!). In 2018 they had lower earnings (less than $4,000) as they started their own business - still supported financially but consequently I didn't claim them as dependants. They didn't file 2018 US returns - probably in error - and they certainly won't have tax to pay.
What's the easiest way for them to 'come clean' and file? Streamlined Filing process, but just for 2 years? - no FBAR filing surely?. I'm keen to get them sorted as they may even be eligible for stimulus checks!!
Thanks for advice here.
