I'd really appreciate any help/advice here. Tis a pretty straightforward one;
I'm helping a couple; wife is a british citizen and husband is australian with indefinite leave to remain - no public funds.
Can the wife claim working tax credits and does she have to include husband on claim form?

Yes she can claim Working Tax Credit and they will need to make a claim as a couple, so his details will need to be included.

If her husband has ILR( indefinite leave to remain) there is no restriction on him claiming benefits. However, you have to make sure that is the case (ILR), because if someone has limited leave to remain which is usually 2 years before the ILR this will be with no Recourse to Public Funds which means he is subject to immigration rules and claiming benefits will potentionally jeopardise his stay.

Hope this helps


P.S if you check hisVisa Status let us know if it is ILR or LLR
