Quinn Moran
Co-founder, iReside
Quinn Moran is a co-founder of iReside, the iPhone app that counts the days you spend in each US state, Canadian province and country by GPS, so tax residency thresholds and visa stay limits are tracked without logging anything by hand. Quinn writes most of the guides on this site.
What Quinn writes about
- State tax residency: the 183-day rule, domicile, and how states like New York and California audit people who move away (see the state-by-state rules).
- Proving residency: what records count as evidence, and why a day-by-day log beats a calendar reconstructed after the fact.
- Visa day limits: the Schengen 90/180 rule and other countries’ visa-free stays (see the visa rules index).
How these guides are written
- Every day threshold, rate or rule cites the statute, regulation or agency page it comes from, with the year.
- Tax numbers are signed off by Quinn before they are published.
- Each guide shows when it was published and when it was last updated.
- The guides are general information, not tax, legal or financial advice. Confirm anything you plan to rely on with a qualified professional.
