The government says the Island's egaming industry swelled its coffers by almost £20 million last year.
A freedom of information request asked how much the sector had brought in to the Isle of Man over the past 12 months.
In response, the Treasury says a total of £19.98 million was raised via income tax, National Insurance and gambling duty.
In its response, the government said more money was raised via the Gambling Supervision Commission.
