Tax residency tracker apps 2026: seven day counters compared

Before the table, our position, because it matters more here than anywhere else. Taxlag comes from the same publisher as this site, Radif Partners, so we have an interest in you choosing it. To limit that effect, here is what we did: for the other apps, we report only what their publisher writes on its own download listing, read on 3 November 2026. We have not installed or tested them, so we make no claim that they work well or badly. For Taxlag, we describe the product as it exists today, including what is missing. The simulator above has nothing to do with any of these apps: it is this site's free counter, with no account. It simply shows why keeping a running count can help: 142 days in 2025 and 140 days in 2026 stay under 183 each year, yet together they pass the 280 days of Ireland's two-year rule.

The comparison, from what each one states

"Not stated" means the listing we read does not mention it, not that the feature is missing. Features and prices change, so check before you commit.

The list makes no claim to be complete: these are the apps of this kind whose listing we could read. The order is not a ranking, except that Taxlag comes first so that our interest shows straight away.

What Taxlag does, and what it does not do yet

Taxlag keeps a presence log: for each signal, the date, time, country, nearby city and source. A correction is added to the log without erasing the original, and it shows in the report. On the web, which is where you use it today, you can note where you are right now, rebuild the past from a Google Maps export or your photos, and ask whether a planned trip crosses a threshold. It produces a signed PDF that can be checked on a dedicated page, a CSV file, and a read-only link for an accountant, valid for 30 days and revocable. Alerts go out by email when a threshold changes level.

Automatic tracking depends on the iPhone app, which has not been released. Until then, do not count on a continuous record: on the web, what is not noted does not exist. Android and payment are not built, so we cannot give a price.

Choosing by your real constraint

If privacy comes first. Look at where your location goes. Several listings state on-device storage and no account. Pebbles does without GPS. Taxlag works differently: it has a server and an email account, and keeps only the country and city, discarding the coordinates. Read the privacy policy of whichever you pick, since a listing is only a statement.

If you may have to show the count one day. An exported file is not worth the same as a record where any change shows. Domicile365 and Taxlag both speak of a signed, verifiable PDF. To our knowledge no authority has endorsed this kind of document, and an app's record remains one item among others: the Czech authority, for instance, names bank statements, personal records and travel or accommodation documents, and recalls that the burden of proof is on the taxpayer.

If your rule is unusual. A generic 183-day count is no help in the UK, which counts midnights from 6 April, or in the US, which weights three years. Tax Residency Tracker states several counting modes. Domicile365 states tools for the UK and US tests. Check that the app can set your country's window, way of counting, and operator, "more than" or "at least".

If you only want to know where you stand. You may not need an app at all. The counters on this site work with no account, from the trips you enter, and your dates go to no server. That is enough for a simple year, as long as you keep your dates somewhere.

What none of these apps can do

An app sees your movements. It does not see your home, your family, your centre of economic interests, or the treaty between two countries. Yet those often decide: France sets no number of days in the sources we read, and the dual residency test starts with the permanent home. So a counter in the green does not tell you that you are in the clear. It answers the question of days alone, which assumes you have checked in the country table that days are the question.

Add the quality of the record itself. All location tracking depends on the phone, its settings and the network: days can go missing or be wrong. Read through your log from time to time, and keep your boarding passes alongside it. To try our tool, the Taxlag app opens in your browser.
