We only report data by three income groups because the number of sectors and more income groups together would produce a number of cells with to few observations to reveal.The "no income" group contains those corporations with income less than or equal to zero. The "positive income" group is those with income greater than zero but who still have an income so low they only pay a minimum tax. (Generally below $2,000, but it can be higher if the minimum tax is a multiple of $100 becasue the filing group contains more than one corporation.) The "taxable income" group is the remainder, those who are subject to the 5% coporate income tax.
Credits on these pages are reported in two ways. The amount reported on the form is designated as "claimed." But often times taxpayers will not have enough taxes to use the full credit, in which case we only report as “allowed” the amount that can be used. It should be noted in some cases that taxpayers will only claim the amount allowed, so the claimed amount may be lower than the amount earned.
