The FAI will receive $1.5m (€1.2m) as part of FIFA's Covid-19 Relief Plan which has been approved by the Bureau of the FIFA Council.
As part of the plan, $1.5bn (€1.28bn) is being made available to support all 211 FIFA member associations - including the Republic of Ireland - and the six confederations to help offset the huge financial impact of the pandemic.
The package, which was drawn up last month, has now been rubberstamped.
A grant of $1m is being made to each member associations, with an additional grant of $500,000 allocated specifically for the women's game. The money will be made available by January 2021.
The associations will also be able to apply for interest-free loans amounting to up to 35% of their audited annual revenues, up to $5m (€4.25m).
In a statement, FIFA said that countries will be able to use the funds to help "the restart of competitions, the implementation of return-to-play protocols, the participation of national teams in competitions, the hiring and re-hiring of staff, the maintenance of football infrastructure, and general administration and operating costs".
"This relief plan is a great example of football's solidarity and commitment in such unprecedented times," added FIFA President Gianni Infantino.
"I would like to thank my colleagues of the Bureau of the Council for approving the decision to move forward with such an important initiative for the benefit of all member associations and confederations."
