A TCAS system check was performed before flight and indicated OK. During climb; a TCAS FAIL annunciation was noted by both crew members. I; the Second in Command and Pilot Monitoring; stated that a report to ATC was required for TCAS failure; which may or may not result in being unable to operate in RVSM airspace. The Pilot in Command declined to make a report; stating 'it does this sometimes; probably a weight-on-wheels switch'. I again insisted that it was a requirement; but he reiterated his position that he didn't want the hassle of reporting it and getting it on the record. He then asked what I would do if I were making an oceanic crossing and TCAS failed. I stated that I would report it to ATC as required; which if before coast-out may result in denial of entry into oceanic airspace. He questioned my judgement on this; saying 'sometimes you gotta do what you gotta do for the flight; and just keep quiet.' I then stated that we needed to file a report via the company; which he dismissed. I'm filing this report independently for my own protection.
Air taxi First Officer reported the Captain did not report to ATC a malfunctioning TCAS system.
