Hi csmerenda
An IVA can be structured in a variety of differing ways, so in principle your suggestion would work. The problem is, however, that there does not appear to be any certainty about your increased earnings at the end of this forthcoming year.
An insolvency practitioner and your creditors would be very nervous about accepting an IVA on such unconfirmed terms. How much is your disposable income now, and how much are your debts in total? It may be possible that you can do an IVA now, without worrying about having to increase payments at a later stage?
