The means test for ESA(IR) is as follows
24 hour work rule for ESA(IR) Asset rule for ESA(IR) Income rule for ESA(IR) If you are asking if your husbands income will count with regard to Carers Allowance, then this will depend.
First, your husband needs to be providing you with 35 hours care a week to be eligible for CA. He can earn wages from an additional "job", but not more than £100/w.
The rules regarding what is and is not included in the £100 are complicated and beyond what we can comment on in the forum. You should seek face to face advice with your local CAB or Welfare Rights office for more details on this.
