The introduction of Turkish electronic VAT invoices has been delayed until 1 April 2014 due to continuing teething problems.  Until this date, tax registered persons may continue to use paper-based VAT invoices. The original edict (Tax Procedural Law Communiqué No.421) for the implementation of VAT e-invoices in Turkey was issued last year with a target date of 31 December 2013. This contained rules on VAT compliance and accounting relating to the new regime including the maintenance of supporting accounting bookkeeping electronically from 2015 at the latest on approved software.

Companies must apply secure digital signatures to their invoices. There are special electronic bookkeeping regimes for the tobacco, oil, gas and LPG industries, conforming to standard government formats, Records to be maintained include: sales invoices, purchase invoices, inventories, production records as well as import/export details.
