Tax Residency for Cross-Border Residents: A CRS-Focused Checklist

Introduction

For cross-border residents, especially high-net-worth individuals, determining personal tax residency is a foundational step before any CRS-related reporting. Residency rules vary by country, and your status under each relevant jurisdiction affects what you disclose and to whom.

This article outlines a general approach to determining tax residency, compares the rules in Singapore, Canada, and Australia, and offers a practical self-review checklist to help organize your CRS planning.

General Steps in Determining Tax Residency

While specific tests differ, most countries assess residency based on factors such as physical presence, permanent home, family and economic ties, and intent. A typical process involves:

Reviewing domestic tax law definitions of resident and non-resident.
Counting days of physical presence in the relevant country according to that country's rules.
Considering secondary factors like the location of your permanent home, spouse, dependents, business interests, and social ties.
Applying any tax treaty tie-breaker rules if you are considered resident in more than one country.
Documenting your analysis and conclusions for each jurisdiction.

Always apply the specific tests of each country, as they can differ significantly.

Comparing Residency Rules in Singapore, Canada, and Australia

Singapore

Singapore does not tax on the basis of residency for individuals; instead, it taxes income sourced in Singapore and certain foreign income received in Singapore. However, tax residency status for individuals is based on the number of days spent in Singapore in a year:

Resident: If you are in Singapore for 183 days or more in a calendar year.
Resident de facto: If you are in Singapore for at least 183 days over two consecutive years, you may be considered a resident for both years.
Non-resident: If you are in Singapore for less than 183 days in a year, with some exceptions.

For CRS purposes, your tax residency status in Singapore is determined by these criteria.

Canada

Canada's tax residency is not based solely on a day count. You may be considered a factual resident if you maintain significant residential ties with Canada, even if you are not physically present. Primary ties include your dwelling place, spouse or common-law partner, and dependants. Secondary ties include personal property, social ties, economic activities, and a Canadian passport or health insurance.

There are also special rules for sojourners (temporary residents) and deemed residents. In general, if you maintain a permanent home in Canada and spend more than 183 days in a year there, you are likely a resident.

Australia

Australia uses a residency test based on four factors: the resides test, the domicile test, the 183-day test, and the Commonwealth superannuation test. Under the resides test, you are a resident if you reside in Australia, considering your physical presence, intention, family ties, and business/employment ties. Under the 183-day test, you are a resident if you are present in Australia for 183 days or more in an income year, unless your usual residence is overseas and you do not intend to reside in Australia.

The domicile test considers your domicile and whether you have a permanent place of abode in Australia. Each test must be applied in order.

Practical Self-Review Checklist Before CRS Filing

Use this checklist to organize your residency assessment before CRS reporting:

For each jurisdiction where you have tax connections (e.g., citizenship, residence, work, or significant assets), identify the relevant residency rules.
Count your days of physical presence in each jurisdiction according to each country's specific counting method.
Note other ties you have to each country, such as a permanent home, family, business, or social connections.
If you qualify as a resident in more than one country, review any applicable tax treaty to determine your residence for treaty purposes.
Document your conclusion and the reasons, as financial institutions may ask for proof of your residency status.
Keep records of travel dates and ties for each jurisdiction.

Frequently Asked Questions

Do I need to determine tax residency in every country I visit? You generally need to determine residency in each country where you have significant connections that could trigger tax or reporting obligations. This requires applying each country's tests.

Can I be a tax resident in more than one country? Yes, you can be considered a tax resident in more than one country under domestic laws. Tax treaties often contain tie-breaker rules to decide which country has primary taxing rights.

Is CRS reporting based on tax residency? CRS reporting generally requires financial institutions to report accounts held by tax residents of reportable jurisdictions. Your tax residency status determines which jurisdiction's authorities receive the information.

Always consult a qualified tax adviser for your specific situation.
