Taxes erroneously paid within the meaning of this section shall include, but not be limited to, double payment, or overpayment, or payment on state, United States, vacant and exempt land, and the purchase paid for the redemption of lands erroneously sold for taxes.
All refunds under this provision shall be made out of any monies collected by the tax collector from the same source of revenue, or if such source of revenue no longer exists the refund shall come from the general fund collections. The tax collector shall issue a warrant to the claimant and deduct the proper amounts from his next settlement.
