Ours is means tested - I have my tax credits award in front of me. We get 5116.68 for two qualifying children, 2803.56 disability element and 545.34 basic element this totals 8465.58 with adjustment due to income (of 8465.58) equalling a big fat zero!
a disabled child element ( £2800) - for each child within the family on disability living allowance (DLA) or who is registered blind; a severely disabled child element (£1130) - for each child within the family on the highest rate care component of DLA
Sorry I was wrong I meant to right this - the £10k thing is if your salary goes up
The income limit for Child Tax Credit is going down from £50,000 to £40,000 from 6 April 2011. This change means if your income will be over the new limit, your basic Child Tax Credit payment of £545 will be reduced.
The rate at which tax credits are reduced The rate at which tax credits are reduced (known as 'withdrawal rates') as your income goes up will increase to a flat rate of 41 per cent from 6 April 2011. This change means your tax credits payments may go down.
see direct.gov.uk for example The 'elements' [child, disability etc] you're entitled to for a year are all added together and are then reduced if your gross income (before tax and National Insurance is taken off) goes above a certain level. The higher your income, the lower your tax credit payments will be.
As far as I understand, the £2800 e.g. for the disabled child element is simply the maximum you can get... but you might get nothing.
