Corporation Tax

The Corporation Tax insight gives an estimate of the corporation tax accrued by a company for the current and previous financial years, based on UK tax rates and using the financial year-end dates in the Xero settings.


Corporation Tax is available for Xero clients only.

In terms of how the different elements are calculated, Dext Precision starts your team off with some defaults based on the chart of account’s Account Type and the Reporting Codes provided by Xero.

Client specific configuration

Reporting Codes are applied to all Accounts, and can be customised in Xero by your team. They are a great way of achieving reporting consistency across clients that have different chart of account configurations. But you only have visibility of Reporting Codes if you are a Xero Partner, and sometimes it is not feasible to configure these for every client you work with.
Dext Precision allows you to override the default corporation tax calculation for a client. By clicking on the cog beside an element of the corporation tax view you will see what is currently being used for that section of the calculation.

Clicking “change” allows you to specify individual account codes to either include or exclude,

depending on the section:

Specifying account codes means that the default calculation will no longer be used for this client, and Dext Precision will instead use the account codes provided. Upon clicking Save, the corporation tax will be recalculated for current and previous years based on the new configuration.
You can remove account codes from the calculation at any time, and removing all of them will result in the calculation reverting back to using the Dext Precision defaults.

Capital Allowances

The Capital Allowances section of the Corporation Tax insight uses the Fixed Assets register in Xero to look for registered assets purchased during the date period. It specifically looks for:

  • Fixed Assets with a status of “Registered” (i.e. Draft won’t count)
  • Fixed Assets with a purchase date that falls within the start and end dates you’ve set at the top of the Corporation Tax view

Scheme Thresholds


Our VAT tools are currently available for Xero clients only.

For the Cash and Flat Rate schemes, Dext Precision monitors your taxable turnover to ensure that you remain on the right scheme from a compliance perspective, using HMRC’s defined thresholds.
For example, you’ll get an alert at the top of the VAT insight if you exceed a threshold:
And similarly Dext Precision also warns you if you are approaching a threshold:

Payment Detection

Precision will try and detect if a previous period’s accrued VAT has been paid to HMRC or not, by searching for reconciled bank transactions within 6 months of the end of the period, with:

  • a GL Account with the Reporting Code of LIA.CUR.TAX.VAT
  • a payment amount within a 2% variance of the estimated amount for the period

If such a payment is found, the Payment Detected field will be set to “Yes”. Clicking on this will take you straight through to the bank transaction in Xero.
