The trio were among 12 players handed test contracts, which ensures that they will have their salaries paid in full by the ECB, and are first time recipients after all three scored their maiden centuries in the longest format in the last 12 months.
"In light of the impact of COVID-19 on the finances of the game, the Team England Player Partnership, on behalf of the players, and the ECB are currently finalising the levels of player remuneration for the next 12 months," the ECB said.
"A further statement will be made once these discussions have concluded."
The ECB said that test players will continue to be rewarded significantly higher pay compared to white ball players.
Players in both formats are ranked based on performances on the pitch, as well as off-field contributions, fielding and fitness before their remuneration is decided, the ECB added.
