Saudi Arabia is tripling its value added tax (VAT) as part of austerity measures to support its coronavirus-hit economy.
The government in Riyadh also said it will suspend its cost of living allowance to shore up state finances.
The oil-rich nation has seen its income plummet as the impact of the pandemic has forced down global energy prices.
The kingdom first introduced VAT two years ago as part of efforts to cut its reliance on world crude oil markets.
Saudi Arabia's state news agency said VAT will increase from 5% to 15% as of 1 July, while the cost of living allowance will be suspended from 1 June.
The allowance of 1,000 riyals ($267; 245 euros) per month to state employees was introduced in 2018 to help offset increased financial burdens including VAT and a rise in the price of petrol.
"These measures are painful but necessary to maintain financial and economic stability over [the] medium to long term... and overcome the unprecedented coronavirus crisis with the least damage possible," finance minister Mohammed al-Jadaan said in the statement.
