Your code it's a bit strange,but here's a possible fix:

pawn Код:

forward Taxes(playerid);
new SetTax[MAX_PLAYERS];

OnPlayerConnect(playerid)
{
   SetTax[playerid]=SetTimerEx("Taxes",30000,true,"i",playerid);
   return 1;
}

OnPlayerDisconnect(playerid)
{
   KillTimer(SetTax[playerid]);
   return 1;
}

public Taxes(playerid)
{
   //code
   return 1;
}

Don't use SetPVarInt with a timer anymore...try to adapt your code following the example I gave you
