Different domain extensions are managed by different registries, and depending on how that registry processes transfers, you may need to renew the domain name as part of the transfer - others allow domain names to be transferred at no cost (retaining the original expiry period without a renewal).
Most ccTLD (Country Code Top Level Domain) extensions are free to transfer. For the remaining domain extensions that incur a cost to transfer, an additional year’s registration will be applied to the domain on completion of the transfer.
