Is the correct English idiom "in regard(s)" or "with regard(s)"?

Question

I know there are a load of combinations and I need to know exactly when you should use which and under which circumstances. If you do GMAT, I'm sure you might know...

Which ones are correct?
- In regards to...
- In regard to...
- With regard to...
- With regard to...

Answer 1

Depends on how you use it.

IF you are, for example, writing a letter and talking about a certain subject, say, "ant farming" you might say:

In regard to your questions on ant farming, I would have to refer you to our local expert, Philip A. Wheeler, author of The Non-Toxic Farming Handbook.

If you were signing said letter, your closing could be:

With Regards,

Here's what Bartleby has to say:

In and with regard to, regarding, and as regards are all Standard, synonymous prepositions, slightly longer and more varied than but meaning much the same as about and concerning: I spoke to him regarding [as regards, in regard to, with regard to] his future. With regards to is Nonstandard and frequently functions as a shibboleth, although it can be Standard and idiomatic in complimentary closes to letters: With [my] regards to your family…. In regards to, however, is both Substandard and Vulgar, although it appears unfortunately often in the spoken language of some people who otherwise use Standard. It never appears in Edited English.

Here's a good reference:

“As regards your downsizing plan . . .” is acceptable, if stiff. “In regard to . . .” is also correct. But don’t confuse the two by writing “In regards to.”

Answer 2

In Regard To Your Question

Answer 3

With regard to -

Answer 4

The correct answer is "with regards to".

Answer 5

Its both "in regard to" or "with regard to". No "s". Compare "as regards"

Answer 6

'With regards to' is correct, 'with regard to' will do. The others with in, do not make sense.
They are a formal way of saying 're:' as when replying to emails.
