A friend has income substantially below $75K; and filed joint return with her husband in 2019. The combined income is over $200K. Accordingly, she received no stimulus check.
If she files separately from her husband for 2020, she should get her $1,400 if and when that is approved by Congress. Would she be able to also claim the 2 stimulus checks that were sent out in 2019 -- based on her 2020 income?
If not, can she amend her 2019 tax return to married, file separately for 2019? If yes, what is the requirements to file an amended return for 2019? e.g. does it require her spouse's consent to file separately?
