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%.
In addition, some staff will be furloughed in the coming days.
The package of measures follows this week’s cancellation of Wimbledon and all the LTA’s summer grass court events.
“This pandemic has the potential to put the continued future growth of tennis at significant risk,” Lloyd said.
“Our primary objective in announcing these unprecedented measures is to ensure clubs and venues remain viable, and coaches and officials are not lost to the sport.”
Venues will be able to access interest-free loans of up to £5,000 from a hardship fund, while full-time LTA accredited coaches and licensed officials will be eligible to apply for grants.
Support grants will also be available to singles players ranked between 101 and 750, and doubles players from 101 to 250, who are not currently in receipt of LTA funding.
