New Mexico specifics that change the number
New Mexico is a community property state. In community property states, income earned during marriage is generally owned equally by both spouses. This affects QJV eligibility, MFS filing strategies, and retirement account contribution rules.
New Mexico is one of the twelve states that still taxes Social Security benefits, which matters if you are drawing benefits alongside self-employment income.
Selling into and out of New Mexico
Income tax follows you: New Mexico taxes your profit wherever the buyer was. Sales tax does not. Marketplace facilitator laws make the platform collect and remit sales tax on your behalf in most states, which is why a seller can have customers in all fifty and still file only one income tax return. Selling off-platform is where that stops being true.
