Looking for opinions here on what to do next.
I paid for a specialist accountant to calculate my tax on a capital gain.
They advised me of the tax due and asked my to approve the amount so they could upload it to HMRC website.
No calculation was supplied to me just the total tax I owed.
I queried it as it was more than I was expecting and the accountant said sorry she had forgotten to update one of the figures and the correct amount was £1,700 less than she originally said.
I nearly said ok to the original figure as I figured she was a professional and knew what she was doing. I have now asked to see the detailed calculation and it looks right to me.
Given that I nearly paid £1700 in tax that wasn't due to to her mistake would I be reasonable in asking for a discount on the fee (which they made me pay upfront)?
