Help!- toilet flange lower than new flooring

i am redoing a bathroom in my house including the floor-

we installed 5/8" plywood and 3/4" hardwood - making the toilet flange lower than the floor.

will the wax compensate for the height difference or does the flange need to come up?

Please help

The toilet flange should sit flush on top of the finished hardwood floor and be bolted to it (with only the thickness of the flange above floor level), and the toilet leveled and bolted to the flange.
There are several ways you can handle it.
The best way, if the toilet closet bend (drain pipe) is accessible in a basement or crawlspace, is to cut the closet bend and raise the flange to the new floor level. If your pipe is plastic, you can easily hacksaw it and install a plastic coupling or a Fernco coupling to make up the difference.
A Fernco is a neoprene rubber sleeve with two stainless steel hose clamps. Easy to install.
If you can't easily get to the closet bend, you can either use one of the new type of Fluidmaster wax-free adjustable toilet seals, or double up two wax rings.
Or you can use flange extenders. Just check for these things at a plumbing store.
Good Luck!
