Frequently asked questions
Is Tax Days cheaper than Monaeo?
Yes, by a wide margin. Tax Days is $29.99/year. Monaeo's individual plan is $99/month or $999/year, roughly 33x the cost.
Why is Monaeo so much more expensive than other trackers?
Monaeo targets ultra-high-net-worth individuals and family offices with high-touch support and audit-tested reports, not just day counting. That service layer, not the underlying tracking technology, is what the price mostly pays for.
Does Monaeo cover international rules like Schengen or the UK SRT?
Yes, Monaeo tracks Schengen and UK SRT alongside hundreds of jurisdiction-specific rules, built for clients with complex multi-country exposure. Tax Days covers the same core rules (Schengen, UK SRT, 80+ rules across many countries) at a fraction of the price, without the enterprise support layer.
Does Monaeo use background GPS?
Yes, Monaeo runs continuous background GPS tracking to build audit-grade evidence. Tax Days tracks automatically too, free, using significant-change monitoring rather than continuous GPS, and your location history stays on your iPhone and in your own iCloud. Manual entry remains available if you would rather not grant location access at all.
Who should actually use Monaeo instead of Tax Days?
Ultra-mobile individuals with multi-million-dollar tax exposure across many jurisdictions, or single-family offices managing tax for multiple principals, where a high-touch vendor relationship justifies the price.
Is Tax Days audit-ready like Monaeo?
Tax Days exports a contemporaneous PDF with day counts per jurisdiction, the same kind of evidence auditors look for. It doesn't include Monaeo's high-touch support, just the underlying records.
