It’s the Truth. It’s Actual.

Quick writing tip:

It’s a fact of life that people get confused about the contraction for “it is” and/or “it has.” Just remember the apostrophe in “it’s” represents the “i” of “it is” and/or the “ha” of “it has.”

It’s the truth. (It is the truth.)

Its, on the other hand, is a possessive pronoun–signifying ownership or belonging.

The monster bared its teeth in anger, and I nearly lost my nerve. (The teeth belong to the monster.)

So, that’s it. It’s a simple rule, and you are responsible for its proper use.
