Sign-ups open before the January filing window.
Nassau County posts new assessments on 2 January, and applications for the 2028/29 tax year are expected to close at the beginning of March. We open sign-ups ahead of that, so there is time to look at your assessment properly rather than in the last week of the window.
While you wait
Two things worth knowing now.
Filing an application cannot raise your assessment, and you are free to file with the county yourself at no cost. Areas we servecarries the county's published figures for your village.
