I am working f/t (approx £33k/year) and partner unemployed (currently receiving benefits, but not living together yet) and was looking to see what might be eligible for. Under 'old' tax credits system the calculator suggests that if partner received JSA or similar then as a household could claim £256 child tax credit, and £367 working tax credit. Are in a full U/C area though and input same details (so partner on U/C already) and apparently not eligible for anything! Any idea why the difference?
