Tekalif-i örfiye was a type of taxation in the Ottoman Empire.
[1][2] Tekalif-i orfiye was a blanket terms for several different ad hoc charges which were, initially, extraordinary taxes raised in war-time.
They were variously paid in cash or in kind, and rates could vary (to an extent), depending on the community's ability to pay.
[3] By the time of the Tanzimat reforms, tekalif-i orfiye included ninety different excise taxes.
[5] However, the Ottoman Empire's complex web of tax exemptions also touched on tekalif; taxpayers could be exempted for public service (for instance, by running a hostel for pilgrims), and sometimes a district's could be exempted due to exceptional hardship (for instance, if the district had already paid heavily towards other taxes, or been ravaged by warfare).
