When you IVA is reviewed by you Insolvency Practitioner, your income forms part of the assessment and if you can pay more, you are likely to be asked to do so.

The IVA is reviewed regularly, some are done 3 monthly and some annually.
You submit wage slips and P60 to your IP so any income above what you are stated will be taken into consideration and a portion of it should be paid into the arrangement.

That portion varies from firm to firm. Usually between 40%-60% in my experience.

Speak to your IP (or staff) about the rules of your arrangement. It should all be set out in your proposal.

However, if your income rises, quite often your expenditure does too.

For example, if I do an extra shift at work it might mean I have to get a taxi home. I need a child minder etc etc. I've been promoted - I need to wear suits etc. So you need to consider those things as well.
