The budget, approved last week on the third attempt by the slimmest of parliamentary majorities, sets the deficit at 2.5 percent of gross domestic product.
The bill sets revenues at 124.9 billion hryvnias ($24.7 billion) and spending at 137.1 billion hryvnias.
The budget was criticised by opposition deputies, who wanted to increase spending on social issues as Ukraine gears up for a March parliamentary election.
A total of 52 political parties and blocs plan to contest the poll, the first public test for Yushchenko's liberal administration which took power after a peaceful revolution against electoral fraud.
