This thread got me researching as I'm in same boat. On page 4 of T1135 PDF (page 1 of instructions) it says

in case that helps

I think you only have to submit a UK tax return if they ask you to. We’ve done the non-resident bit to HMRC and they send a form to my husband, but not me - I assume it’s because of different tax brackets. Having said that, his is always a nil return anyway.

Cheers, as per your last comment. I only benefit when I go back to the UK and do not have to convert currency. The money stays in the UK and has never left the UK.

HRMC has told me I do not have to submit tax returns now and declared me tax excempt. I have not submitted a tax return to the UK for the last 6 years.

Couple of options, see an accountant and get their advice ( I can take a wild guess on the outcome).

Write to CRA, outline the situation and ask for a determination. This should be done in writing, if there is a problem down the road, this letter is useful support for your actions. Again, I can take a wild guess on the outcome.

Deliberately not declaring income, not a good choice in my mind.

Leaving money in a foreign currency, earnings on this need to be reported as well, such as interest or investment income. If you bring any of the funds to Canada in CAD, any gains in the value due to an improved FX rate needs reporting as a capital gain. Disposal of the property, presumably you had a valuation before you left the UK (converted to CAD using the BOC rate on the day you became tax resident). If you sell the property, any increase in value at the time of disposal (converted to CAD at the time of disposal), is subject to capital gains tax.

Might be worth a read?

So looking at it from a tax office point of view, when you go back to the UK you don't use your Canadian income when there because you left UK income there for that purpose. So overall, you would be gaining - including in Canada because you can leave Canadian income in Canada, untouched, if you see what I mean.

For you it makes sense to leave the money there to avoid currency exchange costs - as well as potential fees having the money sent to Canada - but the tax office view will be that you still have the money, however you arrange it.

That is only during the tax year in which they become tax resident. If one became tax resident on December 31, 2017, a T1135 is required for the 2018 tax year.

It was the trust bit that screwed me. I benefit from one. The size of my stake in the trust is anyone's guess. All it does is divvy up dividend income from shares it owns. Pretty much impossible to put a value on that.

I put a link in this post for taxation for new residents to Canada.

It may be of help to you.

Yes, I'm on it! Thank you! Following your link is where I found the above rule.

There appears to be less lag in the system than in the UK... maybe that's just because year end seems to be calendar ye. Feels like I'm reporting UK income a year too early!

Does this declaration include monies kept in non interest bearing bank accounts ?

We still declare a share of a foreign property to CRA every year, despite no income coming from it.

In Canada, you have to report income in the calendar year it was earned (anywhere in the world).

Asset reporting and income reporting are separate. If you have £100k in a UK bank, non interest bearing account (although I cannot imagine why one would do that), this is reported on a T1135. Only interest earned, or capital gain on any FX is reported on a T1.

I wish, no it's just a couple of grand from birthday/christmas gifts etc people put there instead of sending money over.

Canadian taxes have nothing to do with UK taxes. If you are resident in Canada, Canadian tax law applies.
