LONDON - March 19, 2026 - PRLog -- Flamingo Compliance, a tax residency and visa tracking app for multistate and international professionals, has established itself as a leading solution since its launch two years ago. It ranks among the top-grossing iPhone apps in the travel category, including the USA's top 100 and the UK's top 50.
Developed in collaboration with legal and tax experts, Flamingo Compliance helps users automatically monitor and log days spent in different jurisdictions, creating a reliable record for residency, tax, visa, and travel compliance. With its latest upgrade, the app has evolved into a professional-grade platform and positions itself as the market's first comprehensive dual-state residency and tax compliance tool.
Flamingo's upgraded residency and tax tracking removes confusion from managing dual-state residency requirements. Users can set custom rules for each jurisdiction and receive personalized alerts before reaching critical residency thresholds. The app tracks day counts across U.S. states and cities, helping users manage complex tax rules and reduce the risk of unexpected liabilities.
For more complex scenarios, Flamingo Compliance supports advanced tax residency configurations that model multi-year residency tests using customizable rules, weights, and thresholds. This includes frameworks such as the U.S. Substantial Presence Test, as well as state-specific and hybrid residency rules. Pre-configured jurisdiction presets provide a practical starting point that users can tailor to their circumstances.
The app also supports city-level tracking. In many U.S. cities, spending a certain number of days can trigger local tax obligations, including withholding or income apportionment. Flamingo's day-counting tools help users stay informed and maintain cleaner records. Users can also categorize days as residency-related or unrelated based on work activity, improving tracking accuracy.
Flamingo Compliance includes reporting tools that generate clear movement summaries for sharing with tax advisors and legal professionals. The app also stores essential documents, including passports and digital travel records, in one secure place, giving users access to proof of presence without carrying physical copies.
Beyond U.S. state and city tracking, Flamingo Compliance offers international day tracking, long-term visa tracking, and future travel planning. Its enhanced Passport Index, synced in real time with the IATA database, helps users check visa requirements and stay compliant with entry rules worldwide. With bank-level security, user data is encrypted and stored only on the device and in iCloud, with no server access by Flamingo.
