The twenty-year period and annual adjustments
Article 207 of annex II to the CGI places buildings held as fixed assets under a twenty-year monitoring period, against five years for other fixed assets.
- A twenty-year period, including the year of acquisition, completion or first use of the building
- Each year represents one twentieth of the initial tax, the benchmark being the deduction coefficient of the starting year
- Annual adjustment where the year's deduction coefficient moves beyond the regulatory threshold compared with the reference coefficient: additional deduction or partial repayment
- A building held beyond the end of the period is released from any adjustment: the initial deduction becomes final
