If it has been a while since you checked your aircraft timeshare agreements and how your accounting personnel are billing for timeshare flights, give yourself a check-up. Also check-in with the tax advisor to make sure the federal excise tax (FET) has been collected and remitted to the IRS for timeshare flights.
Also, check your insurance policy to make sure your current policy provides coverage for timeshare operations. If you changed insurance agents or insurance underwriters your timeshare flights may have inadvertently been left out of the new coverage.
