The phrase *in regards to (with a plural -s) seems to appear frequently. Even if it is common in texts by both native and non-native English writers, it is not correct.

When you want to refer to something, you can write in regard to or with regard to. Both phrases mean concerning. However, you have other alternatives:

in this regard
as regards
in respect of
with respect to
with reference to
relating to
on the subject of
in connection with
as for

The verb regard can also mean look at, have or show respect for, think of with a particular feeling. The corresponding noun is used in phrases like the following:

I have great regard for his work.
Give my regards to your family.
Best regards.
