Our deficit is 1.5% of GDP so you can easily reduce that by 0.5% to 1% each year by just freezing spending.  As for tax cuts, I think the devil is in the details, but if backloaded to a later date could definitely work assuming they aren't too large and that the size of the tax cuts is below economic growth.  If it exceeds economic growth than it would require spending cuts.  Much of government spending is wages, so just freeze wages until the budget is balanced and then increase them at inflation rates after that.
