Q.  Is it true that if you contracted covid and missed work, you can file it on your taxes and get up to $500 per day of work missed?

A.  No.  There is no such provision on the federal tax return.  Some states have some tax benefits, but there's none that  generous.  Anything available in your state will come up in the state interview.  

As the other answer indicates: those kind of benefits are separate  from the tax filing system. For more info "google" (your state name) Covid 19 tax relief
