Executive Summary
Are RSUs taxed at vest in Poland?
Typically yes for Polish employment: RSU benefits are included in salary income subject to PIT and ZUS when shares are delivered or forfeiture ends—subject to plan design and employer valuation.
Do US citizens in Warsaw pay US tax on equity?
US citizens remain taxable on worldwide income and may claim foreign tax credits for Polish tax paid—subject to limitations and timing differences.
Does a flat tax regime automatically apply to tech expats?
Not automatically. Certain historical or transitional regimes for qualifying inbound workers may exist in specific years—verify current law with a Polish tax advisor. Do not rely on forum posts.
Warsaw and Krakow host major engineering centers for US and EU parents.
Use relocating with equity, Germany guide for border comparison, non-US sourcing.
The bottom line: Verify whether any inbound relief applies to your facts — not your colleague’s LinkedIn post.
