How you can resist funding the government → a survey of tactics of historical tax resistance campaigns → reach out to potential resisters at the time and place of payment → Tax Day actions → 1972

And here is an example of a tax day action from days of yore. From the Troy, New York Times Record of 15 April 1972:

Plan Protest Of Spending For Military

Albany peace workers will demonstrate outside the Internal Revenue Service office Monday noon in their third successive tax day protest against military spending.

The demonstration, arranged by Albany SANE (Citizens Organization for a Sane World) and the Capital Area Tax Resistance Center, will take place on the sidewalk outside the IRS building at 161 Washington Ave., Albany, from 11:30 a.m. to 1:30 p.m.

The demonstrators will offer passersby slices of apple pie of a size to suggest how little is left over for welfare programs after the military takes its share of the national budget.
