sad to say until now the final regulation for the implementation of RA 9504 has not yet come out...
maybe the law was hastily passed and they didn't expect the various negative impact it would cause upon implementing it... anyways, since many of us are still waiting, we were just contented with applying the provisions of the draft regulation that BIR people thinks as final ones, and try to shy away (for the moment) for those gray areas...
anyways, saddened with this news, i would like to share to you an article shared by Mr. Ganhinhin of P&A entitled "Deductibility of losses due to a typhoon". we know the vast losses that typhoon frank leave in it's tracks. so to those accounting people out there, kindly access the link to be able to know how losses due to typhoon will be treated and does BIR allows it.
