Both working tax credit (WTC) and child tax credit (CTC) can include additional 'elements' due to disability, which can increase the amount of your award.
WTC - disabled worker element
This element is a significant one for disabled people. In addition to working at least 16 hours a week, you have to satisfy two other tests - a ‘work disadvantage test’, and be in receipt (or recent receipt) of a ‘qualifying benefit’.
It is the person who meets the work conditions who also has to meet the work disdadvantage and qualifying benefit tests.
So if you are working and not disabled , but have a disabled partner who is not working, you will not receive the disability element. You may however, receive the severe disability element
If you and you partner both meet the rules about working and about work disadvantage and qualifying benefits, you can receive two disability elements.
To get the disability element of WTC included in your assessment, you must have a ‘physical or mental disability which puts [you] at a disadvantage in getting a job’.
This is assessed by the work disadvantage test
You must also meet the required benefit conditions
This is assessed by the qualifying benefit test
How much additional premium is included in my Working Tax Credit?
If you satify the above rules for the Disability Element to be included in your Working Tax Credit an additional £2,790 (from April 2012) or £2,855 (from April 2013)
will be included in your tax credits.
HM Revenue and Customs may ask you to nominate a professional involved in your
care who can confirm how your disability affects you - for example, an
occupational therapist, community or district nurse or doctor.
