The LTA is putting aside up to £20m to help tennis venues, coaches, officials and players through the coronavirus pandemic.
Singles players ranked outside the top 100, who do not already receive funding from the governing body, will be eligible for grants.
Chief executive Scott Lloyd and the rest of his executive team will take temporary pay cuts of 20%.
The package of measures follows this week’s cancellation of Wimbledon and all the LTA’s summer grass court events.
