@fredmach The deemed disposal calculation in the update is not correct, it's far too big.
At the first disposal only the growth on the initial 6000 and first 6000 of monthly contributions should be taxed.
The following year the growth on the next 6000 of monthly contributions should be taxed. And so on.
The file is counting all the monthly contributions made in the first 8 years as part of the growth of the initial 6000. This
significantly overstates the tax (by about 650%) and decreases the ETF value.
The IT has the same problem, 33% tax is applied to the total value of the fund, not the growth of the fund.
