What is the ruling on a person taking money to smuggle gold from the airport, knowing that the state does not implement the legitimate tax law and Islamic Sharia, and what is the ruling on taxes paid to the state?

You must pay the amount estimated as customs or taxes on gold, unless it is proven that these fees are illegitimate, unjust, and not spent on lawful purposes. In that case, there is no blame upon you for evading their payment, even if that involves paying a sum to a person of influence to facilitate the import of gold.
