The number of FSA staff earning more than £100,000 has almost trebled in the past four years.
Figures obtained by the Financial Times via a freedom of information request show the regulator has 241 members of staff on more than £100,000 a year - up from just 81 in March 2006.
The enforcement department saw the number of employees earning more than £100,000 jump to 35 from 10 four years ago - reflecting the regulator's crackdown on breaches of its rules.
The regulator also awarded bonuses to 2,785 members of staff - almost 85% of its workforce - with the largest payout being 35% of salary.
In the enforcement division, 194 people were granted a bonus of up to 15% of salary and 343 earned between 0% and 35% of their salary.
"The FSA needs to attract and retain high-quality people so needs to offer attractive packages, especially when competing with the private sector for specialist talent," FSA spokesperson Kirsty Clay says.
Hector Sants, the FSA's chief executive, was paid £742,000 in 2009/10, up from £623,000 in the previous year. He gave his £130,000 bonus to charity.
