People working for MSPs will receive a one-off cost of living payment of between £300 and £600.
The extra payment will go to all staff who do not pay the highest rate of tax, meaning around 97% will qualify.
Staff earning the least will receive the largest payment.
The money was agreed by the Scottish Parliamentary Corporate Body (SPCB), which is run by a cross-party group of MSPs.
On Wednesday, the SPCB said the cost of living crisis was affecting MSP staff just as it is affecting wider society.
A Scottish Parliament spokesman said: “Similar to other employers in the public and private sector, the SPCB is taking steps to help low and middle-earning staff during the cost of living crisis.”
In April, the basic salary for an MSP increased by 3.4% to £66,662 after it had been frozen the previous year due to the pandemic.
Staff salaries went up by 4.5%.
