## What the new CDTA with Slovenia entails On **4 September 2026**, Hong Kong and Slovenia signed a **Comprehensive Avoidance of Double Taxation Agreement (CDTA)**. This is Hong Kong’s 60th CDTA, set to reduce withholding tax rates for dividends, interest, and royalties for Hong Kong residents investing in Slovenia, and will help address permanent establishment (PE) risks when operating across both jurisdictions. ([ird.gov.hk](https://www.ird.gov.hk/eng/ppr/archives/26090401.htm?utm_source=openai)) Key changes: - Dividends withholding tax in Slovenia for Hong Kong residents will be reduced to a **maximum of 10%** (from up to 25%) ([ird.gov.hk](https://www.ird.gov.hk/eng/ppr/archives/26090401.htm?utm_source=openai)) - Withholding rates for interest and royalties will be **reduced to up to 5%** ([ird.gov.hk](https://www.ird.gov.hk/eng/ppr/archives/26090401.htm?utm_source=openai)) - The agreement will only take effect **after both governments complete their domestic ratification**, including Hong Kong passing an order under the Inland Revenue Ordinance, subject to negative vetting in the Legislative Council. ([ird.gov.hk](https://www.ird.gov.hk/eng/ppr/archives/26090401.htm?utm_source=openai)) ## Tax Planning Implications for Investors ### 1. Revisit your dividend and royalty structuring If you’re a Hong Kong resident or entity receiving dividends, royalties or interest **from Slovenia**, under the new CDTA your withholding tax burden will be **significantly reduced**. This opens opportunities to renegotiate contracts or restructure profit flows to benefit from the new rates. ### 2. Permanent Establishment (PE) risk management The CDTA will provide clearer rules around allocation of profits and PE thresholds. If you have operations in Slovenia or send agents from Hong Kong into Slovenia, ensure you assess the duration and nature of activities to avoid creating an unintended PE, which could bring your business under Slovenian taxation. ### 3. Use foreign tax credits wisely Slovenia tax paid on certain incomes may now be creditable against Hong Kong tax under the CDTA. Profile your streams of income to maximize available credits. Keep precise invoices, contracted rates, and source documents to substantiate claims. ### 4. Timing is critical The rates under the new CDTA will apply only to **income payable or taxable periods beginning on or after** the specified date once the agreement becomes operative. Delay of invoicing or adjusting payment schedules may push income into or out of the treaty’s effective period. Work with your accountant to map your fiscal year to avoid losing treaty benefits. ## Practical Example A Hong Kong-based software company licences IP to customers in Slovenia. Under the old system, Slovenia might have withheld up to **15% royalties tax**. Under the new CDTA, withholding is reduced to **5%**, giving a **10% tax savings**. Multiply this across many licensees, and savings add up meaningfully. On the flip side, if you send a Hong Kong employee to supervise operations in Slovenia for more than ~**183 days or under revised PE thresholds**, a PE may be triggered. It may then shift taxable profits into Slovenia—offset somewhat by treaty rates, but planning or limiting travel/duration could avoid this. ## Actionable Advice Checklist - Review existing contracts and agreements with Slovenian counterparties to adjust withholding and royalty terms. - Consult legal or tax advisors to assess your operations in Slovenia for PE risk before the CDTA becomes effective. - Maintain rigorous record-keeping to support foreign tax credit claims in both jurisdictions. - Align your fiscal and contract calendar to match treaty effective dates to optimize tax positions. - Monitor the ratification process in both Hong Kong and Slovenia to know when treaty benefits are available. --- **Category:** Tax Planning **TaxHome:** HKTaiwan **Author:** NomadicTax Research Team **ReadTime:** 5-8 min **Published:** true
