My partner is recently a legal resident of Costa Rica and is a Canadian citizen; she has no income in Costa Rica but does have income from Canada and the US.
We plan to rent an apartment in the US and need proof of her income. She is preparing her very complicated tax situation for Canada Costa Rica and the US, but has decided to file in Costa Rica her personal income for the purposes of having income proof.
Where are the forms on the Ministerio de Hacienda for filling out a declaration of income for the tributacion? I am also planning on contacting tax attorneys here in San Jose but it will be a lot easier if I can just download the Costa Rican equivalent of a Protected content the US for her to prepare.
