@askc-treasurer ,
Because QBO budgets use monthly amounts or a calculation using the months of the report period vs the quarterly or annual budgets, to get the comparison you want, it appears that it'll involve two reports and exporting to Excel. I would be thrilled if I was wrong, but here's what I see as the workaround:
Prepare a Budget v Actual for the whole year, export to Excel, then again for the partial year, export to Excel. Copy/paste so they're next to one another, and hide some columns.
