The sugar tax will come into effect on May 1st.
It's after the European Commission approved the levy today.
The Commission says the tax is consistent with the government's health objectives to tackle obesity and other sugar related diseases.
It'll apply to water and juice based drinks with too much added sugar.
The tax was announced in the last budget to tackle obesity and other sugar related diseases.
