Just wanted a bit of clarification. The tax credits cap of two children that starts in April. Is it right that this will only affect families who have a third child born after April 2017 and not parents who already have three children? Only I have three children and my youngest is disabled. I have spoken with a few people and they say it won't affect existing tax credit claimants who have three children but then I read online that when existing tax credit claimants are transferred onto universal credit this would be classed as a new claim and the entitlement for the third child would stop. Then again I was told by another person that a move from tax credits to UC wouldn't be classed as a new claim and would be a migrated move so it wouldn't affect existing tax credit claimants who already have three children (born before 2017). Does anyone know?
