Belgian tax on US state/gov't pension?

Hi All,

Looking for answers from anyone who has been in this situation, or is a tax expert.

If my only income is, say, 20 thousand EUR from a non-corporate (i.e. state/government/university) US pension, and I'm a registered resident of Belgium, am I liable for ANY taxes to Belgium? I've read the U.S.-Belgium Tax Treaty of 2006, and the U.S. IRS tax treaty table from 2019, and my impression is that I pay NO tax at all to Belgium, only to the U.S..

Curious if there are any U.S. expat retirees here in Belgium that has any experience with this. Note, that I own no property in either country, do not have a Belgian bank account, and do not generate employment income at all from either country; just a retirement pension.

Thanks in advance.
