what if my wife apply for a tax credit for work or child does it affect my extension.
i am earning 29K annually whereas my wife earning is very low.
As Casa said, you apply jointly with both salaries counted. You earn too much for Working Tax Credits as the cut off for that is about 18k
For children (Child Tax Credits) the cutoff is about 26k for 1 child; about 31k for 2 children and about 36k for 3 children. From April there is a 2 child limit for new claims or new children added to claims.
If you both work at least 16(?) hours each, you might get some help with childcare costs via Working Tax Credits.
Tax Credits is based on the previous years earnings.
Universal Credit is replacing Tax Credits. If you are in an area where Universal Credit is already in for claimants with children, then you will be put on UC and it has different rules. As you both work, you might be better off on UC, but you don't get to choose if you can claim that instead of TCs as it is by areas at the moment, while it is being rolled out across the country.
Your wife can claim Child Benefit, but that cannot be in your name as it is a public fund.
Have you tried the benefit calculators?
https://www.gov.uk/benefits-calculators
These only calulate on the benefit rules for this tax year. The benefit reductions for the next tax year and some of the ones for the year after that, will be listed on those sites separately.
