Tax & Visa Day Counter

Why Tracking Your Days Matters for Tax and Immigration

If you live, work, or travel across borders, the number of days you spend in each country has real consequences. Tax authorities use day counts to determine whether you're a tax resident — which decides whether they can tax your worldwide income. Immigration authorities use day counts to enforce visa limits — and overstaying can result in fines, deportation, or future entry bans.

For expats, digital nomads, and frequent travellers, these two concerns are tightly linked. The same trip data is relevant to both. Yet most tools only cover one or the other, forcing you to track your days twice in separate apps. This tool lets you enter your trips once and check both tax residency and visa compliance from the same dashboard.

Tax Residency Rules You Should Know

The 183-Day Rule is the global standard. Most countries — including Australia, Italy, Germany, France, Spain, and many others — consider you a tax resident if you spend 183 or more days within their borders during a tax year. Once you become a tax resident, you typically owe income tax on your worldwide earnings, not just income from that country.

New Zealand's 325-Day Absence Rule works in reverse. To become a non-resident for NZ tax purposes, you must be absent from New Zealand for more than 325 days in any 12-month period. This is critical for NZ citizens and residents who move overseas and want to stop being taxed on global income. The 12-month period is rolling — the IRD will find whatever consecutive 12-month window works.

The US Physical Presence Test matters for American expats. To qualify for the Foreign Earned Income Exclusion (FEIE) — which lets you exclude up to $132,900 of foreign-earned income from US federal tax in 2026 — you must be physically present outside the US for at least 330 full days in any 12-month period. Full days means midnight to midnight; travel days don't count.

The US Substantial Presence Test applies to foreign nationals in the US. It uses a weighted formula: 100% of days in the current year, plus one-third of prior-year days, plus one-sixth of days two years ago. If the weighted total hits 183 (and you had at least 31 days in the current year), the IRS treats you as a US tax resident.

The UK's Automatic Residence Test uses a midnight rule: if you are in the UK at midnight, that counts as a day of presence. Spend 183 or more such days in the UK tax year (6 April to 5 April), and you are automatically UK tax resident.

Visa Rules for Digital Nomads and Frequent Travellers

Schengen 90/180 Rule is the most complex and most frequently miscalculated. Non-EU nationals may stay in the Schengen zone for a maximum of 90 days within any rolling 180-day period. The "rolling" nature means it's not simply 90 days per half-year — every day you spend shifts the window. Overstaying can result in fines of €500 to €5,000, deportation, and multi-year entry bans.

Thailand has recently tightened its visa-exempt entries. As of 2025-2026, qualifying nationals receive 60 days per entry (down from the 2024 expansion, and potentially reverting to 30 days). A maximum of 2 visa-exempt entries per calendar year is now enforced. The Destination Thailand Visa (DTV), designed for digital nomads, allows 180 days per entry on a 5-year multiple-entry visa but requires proof of remote work and 500,000 THB in funds.

Vietnam's e-visa allows up to 90 days per entry. The multiple-entry version lets you leave and re-enter, effectively allowing consecutive 90-day stays. This has made Vietnam one of the most accessible countries for long-stay digital nomads in Southeast Asia.

Indonesia offers a 30-day visa on arrival extendable by another 30 days. Malaysia offers 90-day visa-free entry for most Western passport holders, plus the DE Rantau digital nomad pass for remote workers.

How to Use This Tool

Start by entering all your trips in the trip log — every country visit with arrival and departure dates. You only need to do this once.

Then switch between the Tax Rules tab and Visa Rules tab to check different rules against your travel history. The tool will count your days, compare them to the relevant threshold, and tell you whether you're compliant, approaching a limit, or over it.

For rolling-window rules like Schengen 90/180 or the NZ 325-day test, the tool automatically calculates the correct rolling period and shows where you stand as of today. For per-entry visa rules like Thailand or Vietnam, the tool looks at your most recent or current stay in that country and counts days against the per-entry limit. Use the Custom Rule option if your specific visa or tax rule isn't listed.

Tips for Staying Compliant

Keep records of every border crossing. Save boarding passes, passport stamps, flight confirmations, and hotel bookings. Tax authorities and immigration officers can request proof of your travel dates, and the burden of proof is on you.

Build a buffer. If your limit is 183 days, plan to stay under 170. Unexpected delays — cancelled flights, medical emergencies, weather events — can push you over. Getting stuck in a country for three extra days should not trigger a tax or immigration violation.
