Pay Capital Gains declared in Self Assessment

From my self assessment I owed both tax and capital gains. Paying the tax was simple but I cannot see where to pay for the captial gains?

Hi,

If you have declared your Capital Gains in your Self Assessment Tax Return and not using the online service, then it is paid alongside your self assessment tax liability. 

Further guidance on paying Self Assessment Tax can be found at:

Pay your Self Assessment tax bill 

If you have used the online Capital Gains services, you can log into your Capital Gains account and pay the tax from there.

Thank you.
