They can derive that info from your tax return in a brutal DARPA-ish database. Your charitable contributions will be noted for your deduction. Your credit card records, too, might tell the tale...or your bank statements. All of this can be researched and pinged without the intervention of a human, to be pulled up by a screener/profiler if it marries up with suspicious travel, unearned income, or some other aspect that causes concern.

In Germany, people do declare their religion. And the government takes the cash out of your paycheck FOR you, to give to your church. It's why so many Germans have no religious preference. They're cheap, ya see.
