Postal tax stamp

A postal tax stamp refers to a stamp which raises revenue for charity or war related projects.Cabeen, Richard McP.; The Standard Handbook of Stamp Collecting, Rev.Ed. (1986). Postal tax stamps are similar to semi-postals, except their use is mandatory instead of voluntary. They are used to show payment of a compulsory tax on mailing letters and parcels. The taxes often go to a charitable institution or fund.{{cite web | last = Klug | first = Janet | title = Inexpensive postal tax stamps offer a collecting challenge | work = Refresher Course | publisher = Linn's Stamp News | date = | url = http://www.linns.com/howto/refresher/inexpensive_20080728/refreshercourse.aspx | accessdate = | archive-url = https://web.archive.org/web/20101228095214/http://linns.com/howto/refresher/inexpensive_20080728/refreshercourse.aspx | archive-date = 2010-12-28 | url-status = dead }}
