Common questions
- Is Tax Residency & Double Taxation Checker legal or immigration advice?
- No. SetTern tools screen cited government and catalog data for planning only. Confirm eligibility, fees, and deadlines on the official portals linked on this page.
- Can this determine my tax residency?
- No. It flags tests you may meet under HMRC SRT, IRS SPT, CRA, BZSt, or ATO rules — consult a tax adviser.
- Does it use live OECD treaty data?
- No. Treaty relief references a static five-country pair catalog, not the OECD API.
