Anthony Weiner’s going to score again.

The taxpayers will have to shell out up to $1.3 million to the randy rep over the course of his post-Congress career.

Under federal pension rules, Weiner can start collecting reduced pension benefits of up to $32,357 a year as early as 2021, when he turns 56, according to the National Taxpayers Union.

Based on cost-of-living adjustments and life expectancy, that could run up to $1.12 million, the watchdog group said.

If he waits until he turns 62, he could get the full pension of up to $46,224 a year, or $1.28 million, it said.

The tax union said congressional pensions are typically two or three times more generous than for workers earning comparable salaries in the private sector. Also, all members of Congress are enrolled in Social Security.
