I created a tool for DTAX which can help to identify from where the differences are coming from. I copied your AC1511 figures and added a column for your tax base figures (you have to enter the figures). The tool shows the difference per PL statement position. Then you are asked to assign the differences to the correct column (non deductible expenses/non taxable income OR temporary differences for positions impacting balance sheet positions OR changes due to tax rate changes).
Please use this tool and try to complete it. Once you have explained all the differences by assigning it to the right column the DTAX data entry form should be easy to complete.
