Do I file Form T400A even if no tax is owed?
Objection, appeal or adjustment obligations of this kind are generally required on the facts rather than on the tax result, so a nil position does not remove one. Taxpayers who disagree with a Canadian assessment, including residency determinations and foreign-reporting penalties.
What happens if I have missed Form T400A for several years?
Missed years are dealt with as a package rather than one at a time, because the route chosen for the first year affects the relief available for the rest. We map the years and the obligations before anything is filed.
Is Form T400A the same as the other reports I already file?
No. The formal objection that disputes an assessment or reassessment and starts the appeals process. Satisfying a different obligation, even one covering the same accounts or entity, does nothing for this one.
How do I dispute a CRA reassessment I disagree with?
You file a notice of objection. Form T400A is the formal document that puts an assessment or reassessment in dispute and starts the appeals process, and it has to be filed within the objection deadline for that assessment. The objection should set out the facts you rely on, the reasons you say the assessment is wrong, and the documents supporting each point. Vague disagreement gets a vague answer. Where the dispute turns on residency, on the source of an amount, or on a penalty, the evidence attached at this stage is usually the evidence the appeals review is decided on, so it is worth assembling properly before filing rather than promising it later.
What happens if I miss the notice of objection deadline?
The objection route closes on its own terms and two narrower doors remain. The first is an application to extend the time to object, which asks for a late objection to be accepted and carries conditions of its own. The second is a request for relief, which does not overturn the assessment but can address penalties and interest. Neither is as good as an objection filed in time, because an in-time objection puts the assessment itself in dispute as of right. If the deadline has passed, say so at the outset rather than filing as though it has not. An extension application is different work, and it starts with explaining the delay.
Does filing an objection stop the CRA collecting the amount?
Objecting changes the collection position, which is one of the practical reasons to file rather than argue informally. The change is not the same for every type of taxpayer or every type of amount, so the answer for a large corporate assessment is not the answer for an individual, and some amounts remain collectible while the objection is outstanding. Interest also keeps running on whatever is ultimately owing. Where the balance is large enough that collection matters, settle that question at the same time as the objection is drafted, and decide deliberately whether to pay, to post security, or to let the balance stand.
Can I object to the CRA deciding I stayed resident?
Yes. A residency determination reaches you as an assessment or reassessment, and an assessment can be objected to. These files are decided on facts rather than argument: where your home was, where your family lived, where your belongings and accounts sat, what ties were kept and what were closed, and when each of those changed. The objection is the place to put that record in order, dated and documented, rather than described in general terms. Because the finding usually affects more than one year and can carry reporting consequences alongside the tax, work out at the start which years are open and which are being decided by this objection.
Do I need a lawyer to file a notice of objection?
No. An objection is a filing, not a court proceeding, and it can be prepared and filed by the taxpayer or by a representative you authorise. What it needs is not advocacy but precision: the assessment identified correctly, the years identified correctly, the facts stated in a way that matches the documents behind them, and each ground tied to the part of the assessment it disputes. If the objection is not resolved at that stage the file can go further, and a well-built objection is what the later steps are built on. We prepare objections on a fixed fee agreed in writing before any work starts.
Can I object to a penalty for late foreign reporting?
A penalty assessed against you comes in an assessment, and that assessment can be objected to. The objection has to engage the basis of the penalty rather than the fairness of it, which usually means addressing what was filed, when, what was known at the time, and what was done once the omission came to light. There is a separate relief route aimed at penalties and interest, and the two are not alternatives to be chosen casually. An objection preserves the dispute over whether the penalty is properly assessed at all; relief asks for it to be waived or cancelled. Which fits depends on the facts and on where the deadline stands.
Do Canada and the United States share tax information?
Yes, through more than one channel. The treaty has an exchange-of-information article that supports both routine and on-request exchange. Separately, an intergovernmental agreement has Canadian financial institutions identify US-reportable accounts and report them to the CRA, which passes them to the IRS, with the reverse flow for Canadian residents. Most other country pairs use the Common Reporting Standard for the same purpose. See FATCA reporting.
How does cross-border tax planning work?
It starts with facts rather than structures: which countries have a claim on you, what each one taxes, and where the two overlap. From there the decisions are about order and timing — which country taxes first, where relief is claimed, and whether a filing or a certificate has to be in place before money moves rather than after. Most of the value is in the sequencing, because relief claimed late is usually relief recovered slowly. See international tax planning.
