A New Financing Opportunity for Taxpayers? Looking Beyond the Reduction in Türkiye's Tax Deferral Interest Rate

One of the most notable recent developments in the Turkish tax landscape has been the reduction of the annual tax deferral interest rate from 39% to 29%. At first glance, this may appear to be merely a technical amendment reducing the cost of deferring outstanding tax liabilities.

However, the General Communiqué on Collection Procedures (Series B, No. 20), published on 16 June 2026, introduces changes that extend well beyond the interest rate itself.

Most notably, eligible taxpayers may now benefit from repayment periods of up to 72 months, compared to the standard maximum period of 36 months. In today's environment of elevated borrowing costs, this development may enable companies to reassess outstanding tax liabilities not merely as overdue obligations, but as part of their broader financing and cash flow management strategy.

That said, the new framework should not be viewed as a permanent change to the Turkish tax collection system. Rather, it provides a time-limited opportunity for eligible taxpayers to benefit from more favourable payment terms.

Why Is the Deferral Mechanism Back in Focus?

Tax deferrals are governed by Article 48 of the Law on the Collection Procedure of Public Receivables (Law No. 6183). Unlike tax amnesties or restructuring programmes introduced through temporary legislation, the deferral mechanism is a permanent legal instrument designed to facilitate the collection of public receivables while allowing taxpayers experiencing temporary financial hardship to continue their business operations.

Historically, however, relatively high deferral interest rates have limited its attractiveness compared to conventional financing alternatives.

The recent amendments may significantly alter this assessment.

The Real Change Is Not Only the Interest Rate

While public attention has primarily focused on the reduction of the annual deferral interest rate to 29%, the most significant aspect of the new Communiqué may be the extension of repayment periods.

Under the ordinary rules, tax liabilities could generally be deferred for a maximum period of 36 months. Under the new framework, active taxpayers maintaining statutory books on a balance sheet basis may qualify for repayment periods of up to 72 months, depending on their liquidity ratio.

Accordingly:

• Taxpayers with a liquidity ratio of 0.50 or above may defer payments for up to 36 months
• Those with a ratio between 0.30 and 0.50 may qualify for up to 48 months, and
• Taxpayers with a liquidity ratio of 0.30 or below may benefit from repayment periods of up to 72 months

Consequently, two companies with identical tax liabilities may ultimately qualify for substantially different repayment schedules based solely on their financial position.

In this respect, the Communiqué introduces a more tailored, financially driven approach to tax debt management.

The 72-Month Repayment Period Is Not Universally Available

Another point that deserves particular attention is that the widely discussed 72-month repayment period does not apply to all types of tax liabilities.

For certain public receivables—most notably Value Added Tax (VAT) and Banking and Insurance Transactions Tax (BITT)—the maximum repayment period generally remains 12 months.

Accordingly, both the nature of the liability and the taxpayer's financial indicators must be assessed before determining the available repayment period.

This Is a Temporary Opportunity

Perhaps the most important practical aspect of the new Communiqué is that it does not permanently amend the general tax deferral regime under Article 48 of Law No. 6183.

Instead, it applies only to eligible public receivables that became overdue on or before 5 June 2026, provided that the taxpayer submits an application by 31 August 2026.

For many businesses, therefore, the principal risk may not be failing to qualify for the new regime, but failing to apply before the statutory deadline expires.

Existing Deferral Arrangements Should Also Be Reviewed

The Communiqué is relevant not only for new applications.

Existing deferral arrangements that remain valid and are being complied with may also benefit from the reduced 29% annual deferral interest rate for future instalments.

However, taxpayers wishing to benefit from the extended repayment periods introduced by the Communiqué may need to submit a new application within the applicable deadline.

Accordingly, existing tax deferral arrangements should also be reassessed in light of the new framework.

Final Remarks

Although the reduction of the annual deferral interest rate has attracted considerable attention, the new Communiqué represents a broader shift in the way tax liabilities may be managed.

For eligible taxpayers, a lower financing cost combined with repayment periods of up to 72 months may provide an opportunity to revisit existing tax debt strategies and cash flow planning.

Nevertheless, this opportunity is neither universal nor permanent. Eligibility depends on the type of tax liability, the taxpayer's financial position and compliance with the application requirements, including the 31 August 2026 filing deadline.

Against this backdrop, companies may wish to ask a broader strategic question:

Could outstanding tax liabilities now represent a financing opportunity that deserves to be reassessed under the new rules?
