[Mormon Red Death]

As a financial clerk I have to say this -

If you don't get reimbursed you are stupid. The church has plenty of money and doesnt want you to unfairly foot the bill.

However, If you decide not to be reimbursed you can deduct it for your taxes. If you deduct it from your tithing it just makes your tax bill higher. Another thing you can do is deduct mileage on your taxes (you generally dont get reimbursed unless its a big trip). Everytime you drive to the church for a meeting see how many miles that is and deduct those on your taxes.
