What a US citizen resident in Canada needs to gather before both returns can be prepared in the right order.
The account and asset lists are the ones that take longest and matter most, because the reporting is tested on facts rather than on tax owing. The plan types decide whether an ordinary Canadian saving vehicle is a US reporting problem, and the last filed returns tell us whether a catch-up route is in play before anything is filed.
Send what you have and we will tell you what is missing. A complete pack is usually the difference between a filing that takes a fortnight and one that takes a season. If you already have an adviser, we will tell you what they should be asking rather than replacing them.

The search that brings most people to this page is international taxes for US citizens. It is answered here for US citizen in Canada: what creates the obligation, which filings discharge it, and the fee agreed before the work starts.
The engagement runs to submission and to the correspondence that follows it, including the queries that arrive months later.
Nothing is priced from a phone call. We read what you have first, then the fee is set — so the scope and the number are agreed on the same evidence.
The heaviest exposure on a cross-border file is usually a disclosure form, not the tax. We identify which ones apply before a deadline turns into a penalty.
Which return goes first decides whether relief can be claimed at all. That sequence is worked out before anything is submitted.
A long-settled Canadian resident learned of the American filing requirement from a bank form asking for a tax identification number. We began with the document pack rather than with a return: slips for the open years, account statements showing peak balances, and the plan papers for every registered account. That produced a written picture of which years were exposed and which were quiet. The engagement ended with prepared returns and information reports filed under a catch-up route suited to the facts, and a document schedule the client now works through each spring before anything is prepared.
The client arrived with a completed Canadian return and wanted the American one built on top of it. We worked the checklist first instead. The exercise surfaced accounts in a third country and a pension left with a former employer overseas, neither of which the Canadian return had any reason to mention. Had the US return gone out ahead of that, an amendment and further information reporting would have followed. The work produced a complete account and asset listing, agreed in writing, from which both returns were then prepared in the right order.
The client had opened a Canadian registered account on ordinary financial advice, with no thought given to the American side. We asked for the plan documents rather than the balance, because the plan type decides whether the account is recognised on the US return. Here it was not. The work consisted of establishing how the plan is characterised for American purposes, what has to be reported while it is held, and what the position would be if it were collapsed. The client received a written note on all three points and made the decision with the cost in front of them.
The client described themselves as an employee with a side business. The side business was an incorporated company, which turned a personal filing into an ownership reporting exercise as well. We collected the incorporation papers, the share register and the financial statements before touching either return. The engagement produced the personal returns for both countries together with the reporting the shareholding required, and a note explaining which of the company's own decisions, from salary to dividend to retained profit, now carry a consequence on the American side.
Only one of the couple held US citizenship, and the household had treated that as a detail. It is not, because joint accounts, jointly owned property and any election to bring a non-citizen spouse into the American return all move the reporting. We took the checklist household-wide, separated what each spouse owned alone from what they owned together, and set out the choices on the joint accounts. The work produced separate document packs, a written recommendation on the spousal election, and returns prepared on the basis the couple chose.
The client could not say which years had been filed in either country, and the account given had already shifted during the first conversation. Rather than ask again, we worked from documents: the assessments still held, transcripts requested from the authorities, and slips reissued where the originals were lost. That produced a year-by-year table of what exists, what was filed and what is open. The catch-up route was chosen from the table rather than from memory, and the returns and account reports followed in the order the table set.
A trust settled in one country and a beneficiary living in another produces reporting for the trust, the settlor and the beneficiary, on different forms and different dates. The engagement maps who files what before anything is prepared.
Read how this one runsWhere the income was on the return and only the account report was missed, a narrow route allows late filing with a reason attached. It is open only while no income is unreported and no examination has begun, which is why it is checked first.

Strategy and compliance for income, assets and families spread across borders.
Foreign property income and sales are taxed in both countries by default; Section 216, FIRPTA and treaty credits are the standing toolkit.
Property is taxed where it sits, which is the one rule no treaty overrides. What the treaty does decide is the credit, the rate on the rent and what happens on the sale — and the clearance certificate on a disposition is applied for before closing, not after the buyer has already held the money back.
Order tax return transcripts from the IRS covering the missing years, and pair them with year-end statements from any accounts you held at the time. Reconstructing the record this way is normal for citizens who moved without keeping copies, and it lets the current filing tie back to what was reported before, rather than starting the file from a blank slate.
Yes. Both accounts are visible to the US side of the return even though they're routine on the Canadian side, so gather opening statements, annual statements, and any withdrawal or contribution records. The account type determines which additional US reporting applies, and that determination is made from the paperwork, not from how the account is normally treated at home.
The Canadian return generally needs to be substantially complete first, because the US return relies on the Canadian tax paid to calculate the foreign tax credit that prevents double taxation. Preparing them in the reverse order usually means redoing the US calculation once the Canadian numbers are final, so gathering both sets of documents together avoids that rework.
Joint accounts still need to be documented in full, not split in half by assumption. Gather statements showing both names and, where the institution records it, each person's share of contributions. How the account is characterized for the citizen spouse's filing depends on that detail, and guessing at the split is one of the more common sources of amended returns.
