The package of tax cuts will total 15 billion Swedish crowns ($2.28 billion), comprising 12 billion in lower income taxes and 3 billion related to a raising of the threshold for incomes subject to central government as well as municipal taxation.
Sweden's four-party Alliance government has already cut income taxes four times since it took power while at the same time cutting welfare benefits.
The Nordic economy contracted unexpectedly in the second quarter, though the government has forecast growth of 1.2 percent this year.
Polls put the Alliance well behind the opposition ahead of an election, due at the latest in September 2014.
