How to pay UK income tax on Swiss Pillar 1 and Pillar 2 (occupational) pensions?

Later this month my husband and I will return to live in UK after 25 years as an expat.
We will both be 66 years age.
We will both have partial Swiss Pillar 1 and Pillar 2 (occupational pensions) which are paid monthly.
How do we pay income tax on these Swiss pensions as we cannot do PAYE?
Do we pay annually after filling in a self assessment form each year, as the exchange rate will change each year?

Hi Jennifer Sims
Please see the guidance at: Tax on foreign income: Overview 
Thank you.
 

Not HMRC...on the basis that you become UK tax resident under SRT and lose SRT Swiss tax residence the pensions are solely liable in the UK (article 18 DTA), you will convert the amounts to £ and declare on SA as foreign income, and pay tax to HMRC via SA. You cannot claim any tax credit from Switzerland so they should not tax the pensions. If you retain Swiss tax residence (so are SRT resident in both countries) then you need to determine the country of treaty residence (article 4) per the DTA.

Thanks, this agrees with what I expected that we pay tax following SA each year and there is no way to ask Swiss pension provider to do the PAYE which is what would happen if UK pensions Is there a published annual exchange rate to use or do I need to convert the Swiss Franc value to GBP every month?

HMRC publish monthly averages and annual averages (to December and March)...but do not define them as "official". https://www.gov.uk/government/collections/exchange-rates-for-customs-and-vat, you can use those (if you keep it consistent each year) or if you want to do it on actual exchange each month then thats ok too...it just needs to be consistent.

I have a similar question. I would like to take my Swiss pillar 2 pension as a lump sum. As I am a UK resident this is possible (age 63). The double taxation agreement article 18 (2) states: Notwithstanding the provisions of paragraph 1, a lump sum payment derived from a pension scheme established in a Contracting State and beneficially owned by a resident of the other Contracting State shall be taxable only in the first-mentioned State. This implies that the lump sum payment shoudl only be taxed in Switzerland. Could you confirm that this is correct?

Hi,
You can do the exchange at the end of the year.
HMRC rates are at:
HMRC currency exchange average rates
Thank you.

Hi Derek Cornes,
You need to refer to the whole article 18 as certain provisions apply.
It is then applied to your personal circumstances which we cannot confirm on this forum.
Thank you. 

Is there anyway to discuss this with HMRC as it is not very clear
