Answer:
Deficit budget
Step-by-step explanation:
Taxes are a form of generating income by governments all over the world to fund expenditure(both recurrent and capital).
Where the revenues generated are more than the expenditure, the budget is said to be surplus.
When it is the other way that is, the expenditure is more than the revenue, it is said to be a deficit budget.
As such, where government takes in $100 million in taxes, but has an obligation of $120 million in government services to provide, this is said to be a deficit budget.
