Overtime and bonuses should be dealt with as they are received and should not lead to an increase at the annual review. Provided you pay whatever is required once you receive the overtime your payments should not go up.

You need to pay in accordance with whatever your IVA proposal states. If you are not sure, check with your IP to ensure that you remain fully compliant.
