Can VAT be backdated ?

In general, value-added tax (VAT) cannot be backdated. VAT is a consumption tax that is levied on goods and services at each stage of the supply chain, from production to final sale to the consumer. It is typically collected by the seller and remitted to the government on a regular basis. Once VAT has been collected, it cannot be refunded or credited unless it was collected in error. If a seller has made a mistake in calculating or collecting VAT, they may be able to request a correction from the tax authorities. However, in most cases, VAT cannot be backdated
