Well Fargo has revealed that the primary residence, or home, can significantly impact your taxes. The company's advisory suggests that this is a financial force, not just salary, but also a significant financial factor. State income taxes can significantly reduce wages and investment income in certain high-tax states, such as New York or California, according to Wells Fargo. For households with multiple homes, the state you legally call home outranks almost every other tax decision in a single year. Moving from a top-bracket state to Florida can save significant five-figure amounts yearly. However, physical presence or other evidence will not satisfy a residency review, as tax authorities examine the new state's lifestyle and ties. Tax authorities also consider the primary doctor, dentist, place of worship, civic memberships, and club affiliations as indicators of permanent domicile.
