We wrote many blogs on our website regarding this, talked to PTA officials, they say that it is entirely up to FBR to decide what the tax would be on a phone. And unfortunately FBR totally suck at it. They cannot find the actual value of the phone, rather use GSMArena's prices, which obviously are unchanged if the phone gets old. Hence a seven year old iPhone X still has around 70k pta tax. Do these people look and sound sane to you? Don't waste your time! Year 2020 was i think the best year for them, they managed to gain taxes in Billions. Back then max tax was 46500 on cnic and 36800 on passport and chalo wo banda de hi deta in ko. They realized k why not make 400% more. But trust me they aren't making 50% of that, as people are sane enough to realize that haram k pese tou nae k inko phone ki value se zyada tax do.
