Providing tax services for U.S. taxpayers with U.S. and Swiss ties.

Founded in 2009 to help Americans with offshore income and assets avoid costly tax reporting errors and increase their after-tax income.

About MHTax

Marina Hernandez founded MHTax in 2009 to help U.S. families with foreign ties simplify their taxes, legally reduce their taxes, and remedy tax reporting mistakes that got them in trouble with the IRS.


For the last fifteen years and counting, MHTax has provided tax preparation, tax representation, and tax consulting services to hundreds of foreign-born families living in the U.S.A. and hundreds of U.S. families living overseas.


In 2014, MHTax started focusing on serving U.S. households with financial and tax lives that crossed the border between the USA and Switzerland.


In 2020, Marina founded Swiss American Wealth Advisors (SAWA) to start providing integrated financial planning and wealth advisory services to these same families.
