The King's staff are set to receive a bonus payment of up to £600 to help them with the cost of living crisis.
The Sun newspaper reported that the bonuses - to be paid on top of this month's salary to workers including cleaners - would amount to tens of thousands of pounds and would come from the King's private income.
Staff earning less than £30,000 will receive a single payment of £600, with staff earning more getting less.
Buckingham Palace declined to comment.
The BBC understands no taxpayers' money is being used and the bonus is being paid from the King's Privy Purse.
This is the money from a private estate known as the Duchy of Lancaster, which covers 18,000 hectares of land. It includes land in areas including Lancashire and Yorkshire, as well as property in central London. The Duchy of Lancaster usually makes a profit of about £20m a year.
