Tax Days vs. TaxDay
First, the obvious thing: TaxDay and Tax Days are not the same app, and not the same company. TaxDay is built by TaxDay LLC and sold at $9.99/month for US multi-state tracking. Tax Days is this app: $29.99/year, 200+ countries plus all 50 US states, with your location history staying on your iPhone. If you searched for one and landed on the other, here is the honest head-to-head. (TaxDay's pricing and features below are taken from taxday.com and its App Store listing as of August 2026, confirm the current numbers there before buying.)

Which one is right for you?
Tax Days is best for…
- Anyone whose travel crosses an international border, not just a state line.
- People who would rather pay once a year than $9.99 every month.
- Anyone who wants the location record to stay on their own phone.
- People who want a permanent free tier rather than a trial that expires.
TaxDay is best for…
- Android users (Tax Days is iPhone-only).
- Anyone who needs a web portal as well as a phone app.
- People who need work days and non-work days classified separately.
- Purely domestic US multi-state workers with no international travel.
Bottom line: TaxDay is a competent US-only tracker, and if you are on Android or need a web portal it is the more practical pick. But it is a monthly subscription that works out around four times the price of Tax Days over a year, it keeps your travel history in its cloud, and its published rule set stops at the US border. Tax Days covers the 50 states plus the federal Substantial Presence Test, Schengen 90/180, the UK SRT, and international country rules for $29.99/year, on-device.
Frequently asked questions
Is TaxDay the same app as Tax Days?
No. They are separate apps from separate companies, and the similar names are a coincidence rather than a rebrand. TaxDay is published by TaxDay LLC at taxday.com and focuses on US multi-state residency. Tax Days is this app, an iPhone app covering US states, the federal Substantial Presence Test, Schengen, the UK SRT, and international country rules. Neither company is affiliated with the other.
How much does TaxDay cost compared to Tax Days?
TaxDay is listed at $9.99 per month, which works out to roughly $120 over a year, following a free trial. Tax Days is $29.99 per year with a free tier that has no time limit. Check taxday.com for their current pricing before you decide, since subscription prices change.
Does TaxDay track international tax residency rules?
TaxDay is sold as a tool for people who work or reside in multiple US states, and the rule set it advertises is the 50 states. Its materials mention recording travel outside the US, but it does not publish Schengen 90/180, the UK Statutory Residence Test, or per-country residency rules as features. Tax Days runs all three explicitly, so if your day-count problem is international, that is the clearest reason to pick it.
Which app is better for privacy?
Tax Days stores everything on your iPhone with optional iCloud sync through Apple's CloudKit and runs no servers of its own, so there is no account and no copy of your location history on a vendor's infrastructure. TaxDay is account-based and describes secure cloud storage for your data; its App Store privacy label reports collecting contact info and identifiers linked to your identity, plus precise location. Both are legitimate designs, they just put the record in different places.
Is TaxDay available on Android?
Yes. TaxDay ships on iOS and Android and offers a web portal. Tax Days is iPhone-only, with a Mac build via Catalyst, so Android users should look at TaxDay or another cross-platform option.
When is TaxDay the better choice?
If you are on Android, if you want a web portal alongside the app, or if you need work days and non-work days classified separately for a state audit, TaxDay does things Tax Days does not. Tax Days is the better fit once international rules matter, when you want a lower annual price, or when you would rather your location history never left your phone.
