Cross-border tax accountants for the US and Canada.

One team coordinates your US and Canadian returns, applying available foreign tax credits and treaty relief to reduce double taxation. Nine US offices, serving every state and province.

49° Nthe line we work either side of
01

American living in Canada

US citizens report worldwide income, so a 1040 can fall due alongside your T1 whenever a filing threshold or other rule applies, plus account reporting and the credits that reduce the double charge.

Start here
02

Canadian living in the US

Residency ties, departure tax, RRSPs held from abroad, and whether the CRA still counts you as resident.

Start here
03

Moving across the border

The year you move is the year that costs the most. Plan the exit and the arrival before you go, not after.

Start here
04

Snowbirds and property owners

Days counted, closer connection filings, rental income on a place across the border, and the tax on selling it.

Start here
05

Years behind on filing

Most people reach us late and expecting the worst. There are catch-up routes that can reduce penalties, but eligibility depends on residency and conduct and has to be assessed first.

Start here
06

Business and contractors

Hiring or selling across the border, permanent establishment risk, payroll in two systems, sales tax and GST.

Do you have to file in both countries?

Three questions, no email address, no sign up. It flags the topics your situation raises. It does not decide which returns are due, because that needs more information than three questions can carry.

This tool is for guidance only. Call for a free consultation.

What is your status in the US?

About twenty seconds. Nothing you tap here is stored, sent or tied to you.

The dates that matter, both sides

Two tax years, two sets of deadlines, and they do not line up. These are the ones people miss.

United States
15 April 2026Regular individual filing and payment deadline. Qualifying overseas taxpayers have a two month extension, but interest on unpaid tax runs from this date
15 June 2026Filing and payment deadline for qualifying citizens and resident aliens abroad. Attach the required eligibility statement
15 June 2026Second instalment of current year estimated tax, separate from the prior year return
15 October 2026Individual return deadline with a valid extension. FBARs receive an automatic extension to this date
15 December 2026Possible discretionary extension for qualifying taxpayers abroad, requested by letter by 15 October
Canada
2 March 2026RRSP contribution deadline for the 2025 tax year. This date moves with the calendar, so check it each year
30 April 2026T1 filing and balance due for most 2025 returns
15 June 2026T1 filing deadline for qualifying self employed filers and their spouse or common-law partner. The balance is generally still due in April
30 June 2026Section 216 return for 2025 where CRA approved Form NR6. Without that arrangement the ordinary election period is generally two years after the income year
31 December 2026Charitable giving cut off. Arrange tax-loss sales early enough to settle by year end, since Canadian securities reporting uses settlement date

How working with us goes

Three stages, one point of contact, and a fixed quote agreed before anything begins.

01

A call, and a straight answer

Twenty minutes with an advisor who does this every day. You leave with an initial assessment of your likely obligations, the next steps and what the work will cost.

02

Documents, once

One encrypted upload covering both countries. We chase the missing pieces, so you are not managing two firms.

03

Filed, and planned forward

Both returns filed and reviewed together, plus a note on what to change before next year.

Roughly what it costs

Every situation differs, so these are ranges rather than prices, quoted in US dollars and exclusive of any applicable sales tax, GST or HST. Representation in an audit or enquiry is quoted separately. You get a fixed quote in writing after the first call, before any work begins.

Straightforward

$900 to $1,600
per year, both countries

Employment income, one or two accounts, no property or investments across the border.

Layered

$1,600 to $3,500
per year, both countries

Rental property, investment accounts, TFSAs or RESPs, self employment, or a move mid year.

Catch up and complex

From $3,500
project priced

Several late years, amnesty filings, corporations, trusts, expatriation, or an estate.

How we approach these

Three situations we handle often. Anonymised client examples will be added here once outcomes and consent are confirmed.

Late years

Where returns have not been filed for several years, we scope the open years first, then assess whether a streamlined or voluntary disclosure route fits the residency and conduct facts.

Years behind on filing
Missed credits

Where foreign tax credits were missed on an earlier return, we check whether the years are still open to amendment and whether the credit limits allow a claim.

Foreign tax credits
Assignments

Before a US assignment, we assess residence in each country, treaty eligibility and the returns required for the assignment and move years.

Questions we get every week

This is general guidance rather than advice on your situation.

I am a US citizen and have not filed since I moved. How much trouble am I in?

Often less than you fear. A streamlined procedure may be available where the failure to file was non-willful. Eligible foreign offshore submissions can receive relief from specified penalties; domestic offshore submissions generally carry a 5% offshore penalty. Tax and interest may still be due. We assess eligibility, residency and conduct before recommending a route. The options narrow once a tax authority makes contact, so the useful time to deal with it is now.

Will I be taxed twice on the same income?

Preparing both returns together lets us apply the foreign tax credits and treaty relief available to you, which reduces double taxation. It does not guarantee that every overlapping charge disappears. Credits have limits tied to the tax, the income category, the source and the timing, and state rules can differ from federal treaty treatment. The result depends on your income, residency and the rules that apply to you.

Is my TFSA a problem?

For a US person it needs a decision. The IRS does not treat it as tax free, so the income is generally reportable. A TFSA or RESP label does not by itself create a Form 3520 obligation, and relief may be available for qualifying education savings trusts and eligible individuals. Trust reporting relief does not remove income tax, FBAR, Form 8938 or PFIC analysis. We assess the account structure and any available exemption separately.

How many days can I spend across the border before it changes anything?

The US substantial presence test uses the current calendar year and the two preceding calendar years, weighting the earlier ones, so people cross the line without noticing. It generally needs at least 31 days in the current year and 183 weighted days. Certain days are excluded and exceptions apply. Canada looks at residential ties, has its own 183 day deemed resident rule and applies treaty residence rules where relevant. Track actual days rather than estimating months, and call before the year ends rather than after.

Do you work with people who are not near your offices?

Yes. The practice is remote by default across every state and province, with video calls and an encrypted document portal. The offices are there for people who would rather sit down with someone.

Lay out your problem and we will do the work to fix it.

Twenty minutes, no charge, and a written fixed quote afterwards. Evening slots on both time zones.
