At present, transgender people over the age of 18 can change their gender on their official documents without the need for medical documentation.
As is sometimes the case in some countries, it is also possible for 16-year-old trans people to recognize their gender, but they must get a legal order.
However, this legislation does not apply to non-binary people who are forced to choose between male or female.
Irish Social Protection Minister Regina Doherty is reviewing Ireland's gender identity law and may change it this year to recognize non-binary people as she said in an interview with The Times.
"While the terms of reference and the composition of the review group have yet to be finalized, I would like to assure you that the views of the transgender community and non-binary community will be essential in informing the review," she said.
Earlier this year, a bill was also introduced in the Irish parliament to allow gender recognition for transgender people under the age of 18. Self-determination would be 16 years old.
It would also allow transgender children under the age of 16 to get legal recognition of their true gender identity.
The Irish government has already said it will support the bill.
