Finance Secretary Derek Mackay has rejected calls by Aberdeen City Council to match-fund a business rates relief scheme.
The authority was offering £3m to help local firms struggling with a rise in their payments.
However, it was conditional on the Scottish government committed to spending the same amount.
Mr Mackay said an extra £7.5m had already been committed to companies in the city.
Businesses in the north east have complained that they are being hit particularly hard because the valuations predated the slump in the price of oil which had an impact on the local economy.
