Tax Day Planner
Day counts decide immigration permission and, in many places, tax residence. Project the year while it can still be changed rather than reconstructing it afterwards.
Day-counting methods, thresholds and the consequences of crossing them differ by country and by the test being applied. This is arithmetic on your own inputs, not legal or tax advice. Confirm the count and the rule with the official authority or a qualified adviser.
Two tests, two counts
Immigration permission and tax residence are separate questions. A visa may allow a stay that a tax rule treats as residence, or a tax treaty may apply a different count from the immigration one. The same day can matter to both, for different reasons.
Keep a dated log of entry and exit days rather than a rough total. If a count is ever questioned, the log is the evidence, and reconstructing it months later is unreliable.
Keep the buffer explicit
A buffer is not padding; it is room for a delayed flight, an unexpected trip or a rule that counts days differently from your calendar. Subtract it before you decide how many days are left.
The planner shows the margin, not permission to use it. Whether a given stay is allowed, and what it triggers, is a question for the authority and, where money or residence is at stake, for a qualified adviser.
Frequently asked questions
Is the 183-day figure a universal rule?
No. It is a common reference in tax systems and a common threshold in visa schemes, but the number, the method and the effect vary. Treat the field as an input, not a default truth.
Do partial days count?
That depends on the rule being applied. Some count any part of a day, some count nights, and some have special rules for transit. Check the definition before counting.
Should I count a visa run as leaving?
Physically yes, but the effect on the day count depends on the permission and on the tax rule. A short exit does not necessarily reset either.
