The Coronavirus Job Retention Scheme (CJRS) comes to an end on 31st October and 30th November 2020 is the last day you can submit claims for periods ending on or before 31st October 2020. After this date you will not be able to submit any further claims or add to existing claims. There is more information about doing that at https://www.gov.uk/guidance/calculate-how-much-you-can-claim-using-the-c....
The Government has also published further information on how businesses can claim the government’s Job Retention Bonus. The bonus will work alongside the Job Support Scheme and could be worth more than 60% of average (monthly) wages of workers who have been furloughed and are kept on until the start of February 2021. Businesses can claim for the Bonus from 15th February 2021 until the end of March and new guidance sets out the information employers who have furloughed employees need to know in order to claim the bonus.
Employers will still be able to claim even if they are receiving support from the recently announced Job Support Scheme, which will protect jobs in businesses facing lower demand over the winter months due to coronavirus. You can get more information on this from the web-site at https://www.gov.uk/government/news/new-guidance-on-9-billion-job-retention-bonus-set-to-benefit-millions-of-businesses and you can check your eligibility and find out how to apply at https://www.gov.uk/guidance/check-if-you-can-claim-the-job-retention-bonus-from-15-february-2021 although the guidance will be updated by the end of January 2021 with how to access the online claim service.
Finally, the Self-Employment Income Support Scheme grant has also been extended from 1st November 2020. You can find out if you are eligible and how much you can get from the web-site at https://www.gov.uk/government/publications/self-employment-income-support-scheme-grant-extension and guidance is available at https://www.gov.uk/guidance/how-hmrc-works-out-total-income-and-trading-profits-for-the-self-employment-income-support-scheme on how HMRC will work out your trading profits and non-trading income if you're self-employed or a member of a partnership and have been adversely affected by coronavirus. A video on how to claim the second grant step-by-step is also available at https://www.gov.uk/guidance/help-and-support-if-your-business-is-affected-by-coronavirus-covid-19.
