Book a callOne document request, one team, one set of numbers that agree with each other.
One encrypted upload covering both countries. We work out what is missing and chase it, rather than sending you between two firms.
We determine the taxing rights and relief for each income item first, because which country supplies the primary tax and which grants relief depends on the income and the treaty rules. The reporting forms are prepared alongside both returns rather than bolted on at the end.
A second pair of eyes checks the two returns against each other before anything is filed, which is the step that catches what nobody else is looking for.
They are returns that were each individually correct and inconsistent with one another, reporting forms nobody knew were due, and positions that were assumed rather than filed. You can only see all three if you are holding both files.
Not all of these will apply to you. Establishing which do is the first half of the job.
It is tempting to think of preparation as mechanical, where the risk is a mistyped number. In cross-border work it almost never is.
The failures we are called in to correct fall into three groups. Returns that were each individually correct but inconsistent with one another, so the credits did not reconcile. Reporting forms that nobody realised were due, carrying penalties that apply whether or not tax was owed. And positions that were assumed rather than filed, which offer no protection when they are eventually questioned.
None of those are arithmetic errors. All three come from looking at one system at a time.
That is the whole argument for one firm holding both files. Not that we can add up better, but that the mistakes in this field live in the space between two returns, and you can only see that space if you are holding both.

Things we do not charge separately for, because they are part of doing the job properly.
Every figure appearing on both sides is traced through. The amounts need not match mechanically, because currencies, sourcing, income categories, paid or accrued treatment and credit limits can differ, so the reconciliation is to the tax actually paid rather than to a matching number. A prepared return is not itself proof that a tax was paid.
Account and asset reporting obligations are assessed every year as part of the engagement, not only when a client thinks to raise them.
A short written note at the end of every engagement covering anything that would produce a better result if handled differently.
This is general guidance rather than advice on your situation.
Yes, and it is common. We will usually want to look at the last two or three years first, partly to understand the positions already taken and partly because inconsistencies are worth finding before another year is added to them.
That is a catch up engagement rather than a preparation one, and there are established amnesty routes on both sides. It usually ends better than people expect.
Two to three weeks from complete documents for a straightforward pair. Anything involving foreign funds, registered plans or a mid year move takes longer, and we will tell you which you are at the quoting stage.
Yes. State residency is its own problem, and a few states are notably aggressive about continuing to tax people who have left.
Every one of these carries a different set of forms.
Twenty minutes, no charge, and a written fixed quote afterwards.
