Frequently asked questions
Is Tax Days cheaper than Domicile365?
Yes. Tax Days is $29.99/year flat. Domicile365's individual plan is $19.99/month, about $240/year, after a 60-day free trial (App Store listing, checked October 2026).
Does Domicile365 cover international rules like Schengen or the UK SRT?
Yes, as separate tools. Domicile365 counts days by country, state, province, and city, and offers dedicated Schengen, Substantial Presence Test, and UK SRT tools. Tax Days runs the Schengen 90/180 rolling window and the UK SRT day count in the same record as your US state and country rules.
Can I share my Domicile365 data with my accountant?
Yes. Domicile365 includes a read-only Advisor Portal so your CPA can see your records, and it produces a cryptographically signed PDF audit log. Tax Days exports a PDF with day counts per jurisdiction that you can hand to your accountant, but doesn't offer a live shared login today.
Does Domicile365 use background GPS?
Yes, Domicile365 records your location continuously in the background and saves it to your account in the cloud. Tax Days tracks automatically too, free, but it uses significant-change monitoring, proposes trips for you to confirm, and keeps the location history on your device. You can also turn location off entirely and log trips by hand.
Is Domicile365 available on Android and the web?
Yes, Domicile365 supports iOS, macOS, Android, and a Windows tray app, and its website shows your logs and signed PDFs. Tax Days is iPhone-only, so multi-platform households may prefer Domicile365.
When is Domicile365 the better choice?
Domicile365 makes sense if you want an accountant-shareable account, multi-platform access, or city-level day counts.
Does Domicile365 handle Puerto Rico residency?
Yes. Domicile365 has a dedicated Puerto Rico day-count test. Tax Days counts your Puerto Rico days toward the 183-day presence threshold, but it does not yet run the full bona fide residence test, so if Puerto Rico is your main concern Domicile365 is the more complete option today.
