New York Gov. Andrew Cuomo on Tuesday filed for retirement as he prepares to leave office in one week, Comptroller Tom DiNapoli's office confirmed. 

Cuomo's retirement will take effect on September 1 in keeping with a state pension requirement that an application for retirement must be on file for at least 15 days, but not more than 90 days, before it can occur.

Cuomo's pension benefit could be worth as much as $50,000 a year, according to the Empire Center, an Albany-based think tank. 

Cuomo's pension benefits would be unaffected if he were to be impeached and convicted by lawmakers.

The comptroller's office last week said as of July 31, Cuomo has accrued 14.56 years of service credit under the Tier 4 pension plan in New York. The time includes his 10 years as governor, along with the four years he served as state attorney general. 

Cuomo's current salary is $225,000 a year.
