tax credits- the salary limit for qualifying for working tax credits as well as child tax credits?

[Linnet]

To qualify for Child tax credits and Working tax credits you have to have a joint income of under a certain amount, does anyone know what this amount is? I've been trying to google it but I'm very confused and don't seem to be getting anywhere.

If anyone knows or manages to come across it at any point could you maybe let me know please?

Thanks

WTC for a couple with children is payable where the joint salary is less than £17.8k approx from memory.

CTC is payable upto around £50k (may be a little higher) but obviously tapers - usually over £25k you only get the bare minimum of £42 a month.
