Does anyone have a specific way of handling tax-deductible transactions?

Does anyone do something to keep track things you can write off your taxes, like charitable donations? Right now I just note it in my notes column and ctrl+f when I need to go looking but it seems like there’s gotta be a better way.

You could add a ‘Tags’ column and create a tag that you use on all of those. That would allow you to filter on that sheet, or better still, use the Tags Report template.
