I subscribed to receive a weekly torah study booklet (Chayenu) but was forced to cancel the subscription a few weeks in due to certain circumstances.
Can the money i paid for the year subscription be taken off my maaser money being that i will not receive the booklets anymore and the money was technically given to a torah organization which relies on donations?
It depends if you are halachically entitled to get your money back or not. If you are entitled to get your money back, then it is essentially owed to you, and you can take it off as maaser instead of taking it back. However if you are not halachically entitled to that money, then it was given for a service for which you had to give them the money, and then you would not be able to take it off ma’aser.
