The Gender Pay Gap Information Bill was passed on Monday.
A law that will force companies to report pay differences between men and women will be voted on in the Dáil today.
It's after the Gender Pay Gap Information Bill was passed in the Seanad on Monday.
The bill was originally published in April 2019.
But it lapsed with the dissolution of the Dáil in 2020, and was restored later that year.
It'll require employers over a certain size to publish pay differences between female and male employees, including any bonuses.
The government's legislation will initially apply to businesses with over 250 staff, extending to smaller companies over time.
But Fine Gael senator and former minister, Regina Doherty, says it doesn't go far enough.
"We could've been far more ambitious here. We need to make that women and men get treated equally, that isn't and hasn't always been the way," she said.
Regina added that so few companies employ 250 people or more, so this is only a "very small" start.
The unadjusted gender pay gap in Ireland was 14.4% in 2017 (latest CSO stats available).
It'd slightly lower than the EU average.
