Sorry Hotguess must be my calculator. I gather you agree with Crashy’s calculations.
I don’t know what BTW means
If you are asking me a question regarding tax credits in the UK I don’t know and I don’t know if tax credits are transferable between Australia and wherever you live. I am guessing you live somewhere other than Australia? From memory some governments have arrangements between one another regarding this issue but I don’t’ know who has what with who.
I appreciate your assistance if I have been presumptuous I apologize.
