Claiming Foreign Tax credit rate

Hi All I’m trying to fill in the foreign tax section of the HMRC online tax return. When I choose Yes in “Do you wish to claim foreign tax credit relief?” I have to chose a % tax rate. I know the amount of tax payable in Australia but to get the % what Income amount do I use ? It might be easier to state some numbers to see what I mean. Assume (not accurate): 8k Australian earned income 5k Australian franking credits on dividends 7k UK income taxable in Australia and UK 35k UK income taxable in Australia but not in UK (pension lump sum) -30k pension contribution in Australia (Also complicating matters in the tax free threshold in Australia of 9k which I think I ignore) My net taxable income (on which I pay tax) in Australia would be 25k (8+5+7+35-30). Is this the amount to use as income in calculating the foreign tax credit % ? So if I pay 5k tax in Australia, the % is 20% ?? Or do I ignore all of the UK income, or the UK non taxable income ? Also, when filling out the section there is a field “Foreign tax taken off or paid: (optional)”. Do I put the tax paid against the particular income in here (as well as in the foreign tax credit area) ? Thanks for any help Ellen

Pls ignore this. I think I understand better now - the tax rate used is that specified in the DTA with Australia and the UK, 10% for interest, 15% for dividends. Thanks

Hi Ellenbf42 F,
Please have a look at the double taxation tax treaty between the UK and Australia:
2003 Australia-UK Double Taxation Convention - in force Updated 31 May 2021
Article 10 covers dividends.
For most individuals the relief rate is 15%.
You can find tax treaties for the UK and other countries on this internet.
Search for 'tax treaties uk / xxxx'.
The FTCR will be up to a maximum of 15% of the Australian dividend received, depending on how much UK tax is payable on all of the dividends in the tax return.
Thank you.
