Hi all,

I’m a Dutch tax resident using an Interactive Brokers account based in Ireland, and I’ve run into an issue with Irish withholding tax (DIRT) on interest.

From what I understand:

• I need to use Form IC5 to reclaim DIRT already paid
• I need to submit Form 8-3-6 to prevent future withholding (treaty relief)
• Both forms seem to require certification/signature from the Dutch tax authorities (Belastingdienst)

However, I’m reading mixed things online and hitting a wall:

• Belastingdienst seems to not want to sign foreign tax forms
• Some sources say you need a “woonplaatsverklaring” (certificate of tax residence) instead
• It’s unclear whether Irish Revenue accepts that in place of signatures on these forms

Questions:

1. Has anyone here (NL resident) successfully:
   • reclaimed Irish DIRT using IC5?
   • submitted Form 8-3-6 for treaty relief?
2. Did Belastingdienst actually sign/stamp the forms for you, or did you:
   • attach a separate woonplaatsverklaring?
3. If you used a residence certificate instead:
   • was it accepted by Irish Revenue without issues?
   • did you need to resubmit or clarify anything?
4. Any tips on the exact process with Belastingdienst? (email, wording, specific department, etc.)
5. Bonus: did anyone manage to fix this at IBKR level so DIRT isn’t withheld going forward?

Would really appreciate hearing from someone who’s actually gone through this
