Tax year rates for capitial gains tax

Hi, I've in May this year I received an asset from selling shares. I am aware I need to pay CGT by Jan 2026, however if the government do decide to increase CGT, do I pay the rates currently for this tax year as the assest was sold in this tax year or are rates based on the tax year the submission is made. Wanting to see if its best I pay my bill early

Hi
This would be entirely dependant on what the government decide to do at the Autumn Budget.
