it has not been working since last year vs it is not working since last year

The correct phrase is "it has not been working since last year." This construction uses the present perfect continuous tense to indicate an action that started in the past and is still ongoing. The phrase "it is not working since last year" is incorrect because it combines the present tense with the past time reference 'since last year,' which is not grammatically accurate.
