What I'm looking for

I’m looking for a role where I can lead corporate tax compliance and advisory work across entities, strengthen internal controls, and use my tax audit and risk assessment experience to keep organizations audit-ready and compliant.

I’m a tax professional with 20+ years of experience in corporate taxation, tax audits, tax compliance, internal controls, and financial investigations. I’m a Sworn-In Certified Public Accountant (YMM) and a former Tax Inspector at the Turkish Ministry of Finance, bringing deep expertise in tax certification, VAT refunds, tax risk assessment, and regulatory compliance.

In my most recent role as Head of Tax & Internal Control, I managed the accurate preparation and filing of Payroll & Withholding Tax, VAT & Withholding VAT, and Advance Corporate & Corporate Tax Returns for holding companies comprising 14 entities. I reviewed internal tax control systems, coordinated tax provisions and year-end accruals with accounting managers, and advised executives on the tax implications of strategic initiatives.

As Founder of a tax certification and advisory firm, I conducted tax certification audits and prepared detailed certification reports in line with the Turkish Corporate Income Tax Code. I certified the accuracy of corporate tax filings and financial information, supported VAT refund claims with prepared reports submitted to the tax administration, and performed tax due diligence for mergers, acquisitions, and investments.

Earlier, as a Tax Inspector at the Republic of Turkey Ministry of Finance (Board of Tax Inspection), I led comprehensive tax audits, examined accounting records and supporting documentation, and investigated suspected tax evasion, fraud, and abusive practices. I also represented taxpayers before Turkish Tax Authorities and supported companies in administrative tax disputes, and later served as an Expert Witness at the Commercial Courts of Istanbul through expert reports on tax and receivables matters.
