I LOVE this idea! I think that's what I'm going to do, also. However, I have a question about the subcategories. For example: Part of our !@#$ refund will go to paying our 2009 personal property !@#$. I know that after they are paid, I will divide it up into the number of months left until December and just budget a monthly amount (for the rest of this year) but for now, would I put Personal Property Taxes under this Master Category of Tax Refund Allocation or just budget the amount into my regular Personal Property Taxes category under my Transportation Master Category?
I hope I'm being clear enough.
You could do it however you wanted. I wanted to keep a fairly accurate record of where the money went, because big money like that has a tendency to 'leak away' on little things in our bank account ~ pre YNAB, of course!
What I would probably do is budget the money under the Tax Refund category for this month, then negative budget it out of there in the month I needed it to pay the taxes and budget it to the regular property tax budget line. This is just to keep a record or 'money trail' for myself that this is where the money went.
Another way it could be done is with a split transaction when entering your refund to your account register. Split X amount to the property tax category directly as an "inflow" and the rest to your Tax Refund category or various other categories, wherever you need it to go.
