Federal authorities are investigating substantial payments made to the State Assembly speaker, Sheldon Silver, by a small law firm that seeks real estate tax reductions for commercial and residential properties in New York City, according to people with knowledge of the matter.

Prosecutors from the United States attorney’s office for the Southern District of New York and agents of the Federal Bureau of Investigation have found that the law firm, Goldberg & Iryami, P.C., has paid Mr. Silver the sums over roughly a decade, but that he did not list that income on his annual financial disclosure forms, as required, the people said.
