[solved]American questions for British people

Stanley Franklin's mascot was a little man called Raspberry, who appeared as a spectator or commentator in many of his cartoons. Franklin described him as "a little bald-headed, big-nosed, one-toothed, pot-bellied dwarf". When Franklin joined the Sun he added a pigeon - named Percy - as a second mascot.

bbc wrote:At present, people receive the maximum level of tax credits if their annual household income is below a threshold of £6,420. From April, that income threshold will go down to £3,850.
So, when household income goes over £3,850, tax credits start to be withdrawn for every extra pound earned.
Tax credit entitlement for those with an income of above £3,850 will be taken away quicker as their income rises. In technical terms, the taper rate will change from 41% to 48%.
In addition, claimants whose household income increases by up to £5,000 during the tax year currently have that rise ignored when entitlement is calculated for that year. From April, this will be reduced so that any increase in income of more than £2,500 will be taken into account.
In a year there will be further changes. Any family which has a third or subsequent child born after April 2017 will not qualify for more child tax credit.
