Any money received by a municipality from a state loan or grant may be expended without regard to budget limitations and over, above or outside the budget, and such expenditures shall not be charged against the budget. If a municipality temporarily finances the service or improvement from budgeted funds and later is reimbursed by the state loan or grant, such expenditures shall not be charged against the budget. If a municipality temporarily finances the service or improvement from budgeted funds and later is reimbursed by the state loan or grant, such expenditure from budgeted funds shall be a reimbursed expense, and if received after the budget year, shall increase the current budget to the same amount unless the budget had anticipated and included the reimbursement as income.
