Reconciliation items are used to disclose the drivers of the effective tax rate, thereby deriving the effective tax rate. The effective tax rate is a key indicator in Income Taxes. ## Starting Point of the Reconciliation The starting point of the reconciliation is the product of the profit before tax and the applicable tax rate. The following tax rates may come into question in accordance with IAS 12.85: - \[1\] The domestic tax rate of the country in which the parent company is situated, or - \[2\] For enterprises operating in multiple tax jurisdictions, a weighted tax rate In practice, option \[1\] is by far the more common option. Income Taxes supports both options in principle. If a weighted tax rate is to be used, a dummy enterprise with the average tax rate must be created as the parent company (group parent). IAS 12 does not prescribe the structure of the tax rate reconciliation. Income Taxes uses the TRR items most commonly used in practice. ## Navigation The **TRR** workspace is opened under **Company | Deferred Taxes | TRR**. The **TRR** workspace is displayed, for example, as follows: Workspace 'Tax rate reconciliation' ## Data Source of TRR Columns The following columns are displayed in the **TRR** workspace: - **Local GAAP (EUR)** - **Adjustment IFRS (EUR)** - **IFRS (EUR)** - **Late Adjustments** (optional): The **Late Adjustments** column is displayed only if the calculation of current taxes from late adjustments has been activated in the [Toolbox](https://support.lucanet.com/en/documentation/income-taxes/income-taxes/master-data-income-taxes/toolbox.md) master data workspace. {% info-box %} **Late Adjustments** are possible only for foreign enterprises. {% /info-box %} The following table describes the content and data source of the columns: #### Content - **Local GAAP**: - Determination of the expected income tax expense based on the profit before tax under **Local GAAP** \[e. g. HGB (German Commercial Code)\] - Deferred taxes are not included in the starting value of the tax expense in accordance with the P&L, but represent a TRR item - **Late Adjustments (optional)**: Determination of the expected income tax expense based on the profit before tax under Local GAAP \[for late adjustments of the actual taxes\] - **Adjustment IFRS**: Determination of the expected income tax expense based on the profit before tax \[for IFRS income adjustments\] - **IFRS** - Determination of the expected income tax expense based on the profit before tax in accordance with the IFRS - Sum of the preceding columns #### Data origin - **Local GAAP**: **Current Taxes** workspace - **Late Adjustments (optional)**: - **Current Taxes** workspace \[when using Toolbox, i. e. foreign companies\] - Row 19.1-19.13 - **Adjustment IFRS**: - Workspaces: - B/S Comparison - LCF (Loss carried forward) - Others - Summary - **IFRS**: Sum of the preceding columns {% info-box %} **Germany/Foreign Difference** Selected rows are either displayed or hidden, depending on whether a company is assigned to Germany (with German tax law) or a foreign country (see Master data workspace [Toolbox](https://support.lucanet.com/en/documentation/income-taxes/income-taxes/master-data-income-taxes/toolbox.md)). {% /info-box %} ### TRR Tooltips The reconciliation items displayed in the **TRR** workspace are documented by tooltips. Click the icon to display a tooltip with the explanation of the composition of the TRR item. The source workspace, the relevant row, and the assessment basis are displayed: Displaying tooltip in the ‘TRR’ workspace ### Displaying Tooltips in a Table You can also display all tooltips in the table by clicking **Tooltips**: Displaying tooltips in the value table The tooltips are then displayed in an additional column of the table. The **TRR view** button is displayed instead of the **Tooltips** button. Click **TRR view** to return to the original view. ### Validation: P/L and Tax Expense/Profit and Calculated Tax Expense/Earnings The upper section of the workspace is used for the validation of the TRR and the specification of any unexplained difference. It is checked whether the reconciliation items explain the difference between the effective income taxes (original + deferred taxes) and the expected tax expense (EBT x tax rate of the company). Maximum 5% of the expected income tax expense can be entered in the TRR item **Other miscellaneous**. If this limit is exceeded, a yellow warning triangle will appear in the row and the user must add a comment. Otherwise, the **Deferred Taxes** milestone will not be able to be changed into or closed with the **data ok** status. The 5% rule is not specified in IAS 12, but has been taken from an earlier US GAAP provision and has become established in practice. 'Other miscellaneous' section in the reconciliation statement ## Notes ### Notes on Tax Groups The TRR is performed for income tax groups on a stand-alone basis. Special considerations arise only in connection with the allocation of current taxes and the submission of deferred taxes. Both parameters are defined in the **Company** master data dialog. The technical requirements for the allocation of current and deferred taxes are not discussed in detail here. ### Tax Group Member Level At the level of the tax group member, the TRR reconciliation items, such as non-deductible business expenses or tax-free income, are taken from the **Current Taxes** workspace , which applies only to subsidiaries. The determined current income taxes are corrected in the TRR row **Correction of results/tax allocation** and are taken into account in the exact amount at the level of the tax group parent. ### Notes on Partnerships The principle of tax transparency is a special feature of partnerships \[PersG\], which must be observed. The partnership itself is usually subject to trade tax – corporation tax is levied at the level of the partner \[corporation legal form\]. This results in effects at the level of the partnership and partner in the TRR. ### Notes on Reclassification Column The reclassification column can be used to reclassify the values between individual rows. The column contains manual input fields, which are included in the total calculation of the IFRS column. {% info-box %} The reclassification column is not displayed by default. If you need the column, please contact your Lucanet consultant. {% /info-box %} ## Tips ### Tips for Validation Errors Preparing the TRR is one of the most time-consuming activities in practice. The tool therefore simplifies this process significantly. However, certain assumptions must be defined to achieve the highest possible degree of automation. The following points should be observed when validation errors occur in the TRR, i. e. when the TRR does not balance: - Distribution of tax balance sheet corrections in the tax calculation - Balance sheet differences between the HGB (German Commercial Code) and the tax balance sheet do not correspond to tax balance sheet corrections - Changes in IFRS/HGB balance sheet differences do not correspond to IFRS/HGB income differences - The losses carried forward have not been developed ### IFRS/HGB Balance Sheet Differences Do Not Correspond to IFRS/HGB Income Differences The following example is intended to illustrate this case: A difference of 100,000 between the IFRS and HGB (German Commercial Code) is entered in the balance sheet comparison. The difference is entirely temporary. At a tax rate of 20%, this results in deferred tax liabilities of 20,000. The IFRS EBT is consequently 100,000 solely due to this one balance sheet difference. The TRR balances. If a deviating IFRS EBT is entered, the TRR will not balance by the amount of the difference multiplied by the tax rate. In this simple case, the income effect is straightforward. In practice, however, it is not always immediately apparent whether the wealth differences between the HGB (German Commercial Code) and the IFRS documented in Income Taxes result in the correct income effect. The report **Transition P&L results local GAAP / IFRS** is helpful for this. The report shows whether the change in balance sheet differences corresponds to the income difference. You can generate the report by clicking the **Transition P&L results local GAAP / IFRS** button in the **Tax Rate Reconciliation (TRR)** workspace.
