iXBRL Corporation Tax computation

Introduction

IRIS Business Tax includes functionality for a new enhanced iXBRL (Inline eXtensible Business Reporting Language) corporation tax computation that can be filed online to HMRC as part of the corporation tax return submission.

Corporation Tax Returns must be submitted online on and after the 01/04/2011, and the accounts and computation submitted must be in iXBRL format if the accounting period being submitted ends on or after the 01/04/2010. For more information on iXBRL and IRIS, please visit our website by clicking here.

There is further information on changes to online filing on the HMRC website here.

IRIS Business Tax generates the iXBRL computation with the majority mandatory tags required without any further details being required. There are a few areas that have been updated to allow the relevant information to be tagged in the computation. Details of the changes for the iXBRL computation are as follows:

Postings Screen Updated

The posting screen has been updated and now requires users to select an expense or income category when making a posting to the following screens;

This additional information is required so that the program can tag the amount shown in the Trading Profit Calculation on the enhanced tax computation with the relevant tag as selected. The category must be selected for any postings made in this screen now - for example if an adjustment needs to be made for legal costs that must be disallowed from the trading income in the computation, the expense category 'Accountancy, legal and professional fees' must now be selected from the drop-down list.

Business Tax Accounts Screen updated

The Business Tax Accounts screen has been updated so that users can select the relevant expense or income category from the drop-down list of available categories. Users that have customised the Business Tax Accounts in the Edit | Business Tax Accounts screen for a client or globally in the Setup | Business Tax Accounts screen must ensure any items in the Global Disallowed Trading Expense or Global Disallowed Trading Income has relevant expense or income categories selected. This will ensure any accounts postings automatically disallowed in the enhanced iXBRL tax computation will be assigned with the relevant tag as selected.

New enhanced iXBRL Tax computation

A new enhanced iXBRL compliant Corporation Tax Computation has been added to IRIS Business Tax in the Reports / Corporation Tax / Enhanced menu. An option for the Basic corporation tax computation can also be generated but this is not iXBRL compliant.

When the enhanced computation option is selected, users will be provided with a new report output option labelled 'iXBRL' that allows an iXBRL version of the enhanced computation to be generated to a folder specified in the Details screen.

Electronic Tax return updated

The Reports / Electronic Tax Return screen been updated to allow users to attach iXBRL accounts and computations. The 'Select External File' and 'Select from Communication Tracking' options now allows iXBRL documents to be attached to the electronic return. The program will validate that the required elements in the iXBRL document match those of the client that the return is being submitted.

The following items must match the clients details:

When the 'Generate Now' option is used to generate a corporation tax computation, the program will automatically generate and attach the enhanced iXBRL Tax Computation to the submission when required.

IRIS Practice Management Report logging

Users with a IRIS Practice Management licence will now be able to log the enhanced iXBRL Tax Computation in iXBRL format. By default the program will log the enhanced corporation tax computation in iXBRL format. This setting can be changed by in the IRIS Main Menu | System Maintenance | Practice | Report Logging | Tax - Corporation Tax | Corporation tax computation screen.  

 

Multiple Trades

The enhanced iXBRL Corporation Tax computation has been updated, so that it will now automatically include multiple trades.  

Each trade entity on the report is populated using the trade specific data that has been included in Business Tax.

These trade specific items include the following.
