All my income is self employed. Being that I anticipate that my 2013 tax return will me higher than 2012 I told the case worker I want to add 1000 dollars a month over my 2012 income. He told me we don't care what you write all we care is what it says on the tax return and if you only have 2012 that is what we go by. Well good for me because it probably got me an extra year of schip for my children.
