IHS transfer from tier 4 Dependant visa to tier 2 ICT

Hi Everyone.

I got visa for tier 4 dependant visa and paid IHs fees while applying for this visa.
Now my current employee is offering me Tier 2 ICT. Can I use my IHS which I paid for the tier 4 dependant visa or do I need to pay IHS again on a new visa which I am going to apply

Now my current employee is offering me Tier 2 ICT.

Why Tier 2 ICT and not Tier 2 General? Are you still in the UK or abroad? You cannot switch to Tier 2 ICT within the UK. You also need to have worked for your sponsoring company abroad for 12 months to qualify for ICT.

Can I use my IHS which I paid for the tier 4 dependant visa

No. Note IHS for Tier 4 is cheaper than tier 2 IHS.

or do I need to pay IHS again on a new visa which I am going to apply

Yes.
