Description
From the marketplace listing
OmniFlag answers two questions people ask before they move abroad: how much income tax another country would charge on what I earn now, and which countries fit my situation.
Tax Delta compares the statutory income tax on a salary or self-employed income between where you pay tax today and each destination OmniFlag carries, or one destination you name. It covers Ontario, Quebec, British Columbia and Alberta (or federal only for other provinces), the United Kingdom, Germany, the Netherlands and Ireland. It is income tax only, with social contributions left out, and it shows the difference between two tax systems, never a promise about your own outcome. A US citizen or green card holder gets the citizenship-based taxation notice instead of a figure, because the United States taxes its citizens wherever they live. A Scottish taxpayer is told the Scottish bands are not carried yet rather than shown the rest-of-UK figure.
Destination match takes your citizenships, where you live now, your income band, what matters most to you and your hard noes, and returns the closest destinations, each with its key cited figures and one honest downside.
Every figure links to its OmniFlag dossier, which lists the primary government sources and the date they were last verified. Each destination's full write-up, with every route and its requirements, is on omniflag.app. OmniFlag never asks for your name or email inside ChatGPT, and it stores nothing you type. Confirm anything you act on with a licensed professional.
