Hi,
Further to my reply, something I should have posted at the first instance - If the employer pays for a private travel undertaken by the employee & his dependants, for example, a private trip awarded as recognition for superior performance, then this private travel is taxable under FBT. The difference between LTA and private travel is if the conditions of LTA are not fulfilled during the private trip, then those trip expenses are taxable.
If the employee undertakes 2 trips in a year, and both meet the LTA conditions, then I guess it is up to the employee to declare which trip is under LTA and which is a private trip paid for by the employer. Obviously, in my opinion, in this case, the more expensive trip should be declared as LTA, since LTA is non-taxable.
