### Calculating Donation Portion of Invoice
As described in
[IRS 501(c)(3) rules](https://www.irs.gov/charities-non-profits/substantiating-charitable-contributions),
a charity must substantiate portions of a contribution that are RBI, and
portions that are donations separately and inform the donor which portion was
a donation that may be eligible for tax deduction. Use of the `IncomeType`
tag facilities collection of the necessary data to determine the total, and
the following command line will total up all the donation portions for a
particular invoice:
$ entity=BigCorp; program=Foo.*Conf.*2017; invoice=2016-01-30
$ ledger -f accounts/books.ledger -V --sort d --limit 'tag("IncomeType") =~ /Donation/ and tag("Entity") =~ /'$entity'/ and tag("Program") =~ /'$program'/ and tag("Invoice") =~ /'$invoice'/' reg
