1.  Regularization is possible back to 4 years, provided the notification requirement is met (however, the Belgian tax administration (“BTA”) does not allow retrospective application for years prior to the moment of notification).

Note: The partial wage withholding tax exemption is applicable only to projects that have been notified before the start of the project to the Belgian competent authority. Based on this rule, the Belgian tax administration takes the position that a retroactive application (i.e. application for the past once notification is done) is not allowed.

2. This is to be applied in the annual corporate income tax return, covering the most recent taxable period (corresponding with accounting period in corporate tax matters). Unused investment deduction “ID” can be carried forward and applied in subsequent taxable periods without time limit, but capped.

2. This was introduced into Belgian domestic tax law in December 2005 and this measure is quite mature.

1. Claims in regards to the withholding tax on wages benefit can be reviewed by the Scientific Policy Support Agency of R&D (BELSPO), which employs technical experts and issue binding decisions on the R&D character of activities. However, the benefit application is reviewed and audited by the Belgian tax administration (the Federal
   Public Service of Finance).
2. The 13.5% one-off deduction or a 20.5% per year spread investment deduction for fixed assets is administered and operated by the Belgium Federal Public Service of Finance. Claims are not reviewed by technical experts.

1. Withholding tax on salaries paid to eligible researchers on the payroll, provided these salaries can be attributed to R&D activities.
2. R&D expense justifiably capitalized under BEGAAP.

Obtaining “a structural R&D certificate” from BELSPO can help companies support R&D justification of their activities.

2. A pre-notification of the project before applying is mandatory. An environmental certificate should be obtained from the competent Regional authority.
