Actually, if you crouch down and photograph them from the kerb, they probably will look better than they do in that aerial shot.

I think it applies to the whole year but don't over stress it because it's not relevant. That question is only relevant if you're trying to claim you are not UK resident. If you are claiming split year treatment (by putting an X in box 3) you can't have claimed to be non-resident for the whole year (by putting an X in box 1).

Probate (if it's needed) would be in Australia as that's where his assets (and will) are. If he still had assets in the UK it could need to be done in both countries. Probate isn't always needed. It comes down to whether or not any of the organisations that hold his assets need to see the grant of probate before they release the funds.

As you might be earning a lot of interest on those sale proceeds, make sure to let your bank know that you've left the country and are no longer tax resident in Australia. That way they'll deduct 10% tax from your interest (which you won't like) but (provided that's your only Australian income) you won't have an ongoing need to file Australian tax returns. You'll be able to use that Australian withholding tax to pay your UK tax bill. Beware that Australian taxes on non-residents selling Australian property can be onerous (plus there will UK tax to deal with to). You are definitely better to sell your property before you leave (if it entirely qualifies as your main residence, it'll be tax free).

There are no inheritance taxes in Australia and while there is IHT in the UK a SIPP is IHT Free. Take the money now. You'll only be taxed in Australia on any growth that occurred after you inherited it and (because it's a SIPP) there is no UK tax. If you leave it in a SIPP for the next 20 years, there is no UK tax (because a SIPP is tax free in the UK) but there will be a lot of Australian tax to pay when you cash it in (becaus a SIPP is not tax free in Australia). You'll have to pay tax in Australia on the growth of the SIPP over the next 20 years all in one lump year. Even if you are no working that could still be a lot of tax. If you want to keep the money for your retirement (I'm assuming you plan to do that in Australia) you should consider Super or other investments in Australia.

There is a question on every Australian tax return. Final Tax Return? Yes/No. If you've left the country and no longer have any Australian income, you should answer yes to that question and will not be troubled for another tax return. If you leave Australia in July 2024 then your final tax return will be FY2025, but you'll be entering the date that you left Australia as part of the return and your worldwide income only goes up to that date. Any UK income (or other foreign income) after that date isn't included on the return and isn't taxed. Similarly, your first UK tax return will run 6th April 2024 to 5th April 2025 but you'll include the date you returned to the UK on the return and won't need to report any Australian income (or any other foreign income) received before that date. Note that if you still have an interest-bearing Australian bank account, make sure they know you've left the country (provide them with your new address outside Australia) and have removed your TFN from the account details. You'll have 10% withholding tax levied on the interest (which you'll be able to claim on your UK tax return) but won't have any requirement to lodge an Australian tax return if that is your only Australian income. I've had client have to go the expense of lodging Australian tax returns because their bank didn't know they had left the country, and so were reporting their interest and TFN to the ATO triggering the demand for a tax return.

No. You can only have one property as your main residence at a time (other than for a short overlap period) but just because you are living in a house doesn't mean you have to choose that one to be your main residence at the time.

If it was the only property he owned (he said he used the money to buy a property in Australia so I'm assuming he didn't already have one) then provided he lived there within the last 6 years, it was still his main residence and so CGT exempt regardless of being rented out.

Did you live in the property at any point? You can still claim the main residence exemption for up to 6 years after you ceased to live there. You can only claim the main residence on one property at a time though, so it depends upon what other properties you own.

I think the problem might be that when you get a new passport it has a new number. The system ought to recognise the passport number if you previously had a visa on it (and if that visa was cancelled because you became a citizen it ought to know you are a citizen) but harder to catch if it's a new passport.

No. Between those dates is after the Initial Entry Date and if you wait until then you'll invalidate the visa.

That is just wishful thinking. You would still be viewed as having received the pension and taxed on it before you deposited it in the trust. You can't turn your income into trust income. You could turn an asset into a trust asset and then the income from that asset becomes trust income, but to do that you'd need to convert your entire pension fund into a trust asset which would trigger a host of tax issues in both the UK and Australia. If you have any spare cash to invest you might want to put it into accounts opened only in your wife's name as the interest/dividends paid will effectively be tax free.

She has, but the point is that thousands (perhaps tens of thousands) of other people are doing the same thing and don't have a spouse with the political exposure to force them to change.

Normally neither need to pay it back (the only exception is if you paid them too much) since only one will take tax at source. If you have an Australian employer they'll have paid PAYGW, but nothing will have gone to HMRC. If your Australian employment income is taxable in the UK it will need to be reported on a Self Assessment Tax Return. The foreign income pages of the Return (section SA106) have all the boxes necessary to report the amount of tax you have paid in Australia. Only if UK tax due is higher than the tax you paid in Australia will you have to pay any UK tax. If the UK tax is lower you will not get a refund (although if you've been taxed at source on other UK income you might get that tax refunded). It works the same when it's the other way around (e.g. if you have UK income that is taxable in Australia) however as you are on a temporary visa that does not apply to you. If split treatment applies (which is the case if you've permanently moved to Australia) then only your Australian income (and Australian tax paid) for the part of the year you were UK resident is entered on your UK tax return (but UK income for the full year). This might get you a refund of UK tax withheld back from HMRC (if you've paid too much), but there wouldn't be any Australian employment income taxed in the UK so your question about claiming tax back is irrelevant.

Absolutely everything to do with the double taxation system. The Double Taxation Agreement (DTA) between the UK and Australia specifically allocates the taxation of pension income only to the country where the pensioner is resident. This is different to the rules on all other income.
