Hi Ms./Mrs. Monika,
According to the information that I have, you may apply for the renewal of DCI at any time of the year, but if renewal is not provided to the authorities before the end of financial year, i.e. before 31st March, an extra fee will be charged as fine.
So, the conclusion derived is that YES, you may apply for DCI renewal any time of year but complete the renewal process, before the end of financial year in which the DCI registration expires.
You may find more info on the State Dental Council website.
