About this calculator
The Working for Families Tax Credits (WfFTC) 2011 calculator is no longer available. The calculator was accurate for calculating an entitlement for the period 1 October 2010 to 31 March 2011 but it will not correctly calculate an end of year entitlement.
If you file an Individual tax return (IR3) we will send you a notice of assessment advising you of your WfFTC entitlements after we have processed your details.
If you receive a personal tax summary we will send details of your entitlement in July 2011.
Use of this tool does not result in data being submitted to us.
