Tax Days vs. TaxBird
TaxBird pioneered the snowbird-tracking category for individuals. Tax Days takes the same problem, adds international rules (Schengen, UK SRT, 200+ countries), keeps automatic tracking optional instead of mandatory, and cuts the price. Here's a head-to-head. (Pricing below is TaxBird's published rate as of mid-2026, confirm the current number on their site before buying.)

Which one is right for you?
Tax Days is best for…
- iPhone users who want privacy by design.
- Anyone with international travel patterns.
- Anyone who wants 0% data on a vendor's server.
- People who'd rather pay $20/year than $60.
TaxBird is best for…
- Android users (Tax Days is iPhone-only).
- Pure-domestic US snowbirds with no international travel.
- Anyone who needs a web dashboard.
Bottom line: If you're an international traveler, even occasionally, Tax Days is the only one of the two that runs the 90/180 Schengen calculation, the UK SRT, and 30+ international rules. For Android users on a US-only itinerary, TaxBird is a credible choice.
Frequently asked questions
Is Tax Days cheaper than TaxBird?
Yes. Tax Days is $19.99/year with a free tier for limited rules. TaxBird runs $39.99/year (or $4.99/month) with a 30-day trial rather than a permanent free tier.
Does TaxBird track international rules like Schengen or the UK SRT?
No. TaxBird is US-focused: it covers all 50 states but not the Schengen 90/180 window or the UK Statutory Residence Test. Tax Days covers all 50 states plus the federal Substantial Presence Test, Schengen, the UK SRT, and international country rules.
Does TaxBird use GPS to track my location?
Yes, TaxBird auto-detects state crossings using background location. Tax Days can track automatically too on Pro, but it is optional and works differently: it uses battery-efficient significant-change monitoring rather than continuous GPS, proposes trips for you to confirm, and keeps your location history on your iPhone. You can also skip location entirely and log trips by hand.
Which app is better for privacy?
Tax Days keeps all data on your iPhone with optional iCloud sync through Apple's CloudKit, and has no servers of its own. TaxBird is account-based and syncs your location history to its servers.
Is TaxBird available on Android?
Yes, TaxBird ships on iOS, Android, and the web. Tax Days is iPhone-only (with a Mac Catalyst build), so Android users will want TaxBird or another cross-platform option.
When is TaxBird the better choice?
TaxBird makes sense for Android users, US-only snowbirds who want automatic GPS tracking, and anyone who wants a web dashboard. Tax Days is the better fit once your travel crosses an international border.
