The HMRC are likely be to interested in the chart of accounts relating to:
Profit and Loss
Go to the accounts page > profit and loss > click to drill down into each of the income and expense accounts listed in the P&L report. These show all sales made and expenses incurred so are the most important items for tax reasons.
Each of the Income or Expense account can be individually found in Accounts > Chart of Accounts, and can be exported or printed out.
Fixed Assets
Accounts > Chart of Accounts > Drill down into the "Asset" type accounts, if you have configured any.
Since Fixed Assets are not shown in the P&L and may have also given an INPUT to the VAT account, these may also need to be printed out.
Tax Account (this a VAT account)
Go to Accounts > Chart of Accounts > Tax Account
These are inputs and outputs that affect the VAT account. I.e. if you made a purchase and the VAT of that purchase was £10, the £10 can be seen on this report.
