It's pretty common to use present tenses in US English for events in the future or past. E.g. "I'm at the store the other day, and this guy comes up to me...", "I'm visiting the store later"
Perfect tense is common. Future is occasionally avoided like above. Pluperfect and future perfect are almost never used, and most speakers would convey that meaning a different way. E.g. "I'll visit the store before then" rather than "I'll have visited the store". There is also some pseudo future tenses related to "going/gonna" (e.g. "I'm going to do that").
I think tenses are probably taught in some schools, but I didn't learn any of this until I took other languages. The average US English speaker probably doesn't know the names of all the tenses and doesn't even know what subjunctive, indicative, etc. mean.
