How do I create a one-time category for one month?

@jeffmontague, I meant to say “Transactions sheet” there isn’t an account column in Categories. Good catch :wink:

You might want to check out the Savings Budget and Savings sheet for one time expense and savings. Not sure if it’s helpful in your scenario. Otherwise you can just customize the Categories list to include the category and only add budget amounts to the one month you need a budget for it.
