Because of coronavirus (COVID-19), you can delay making your second Self Assessment payment, due in July 2020. If you choose to delay, you’ll have until 31 January 2021 to pay it.
Call the Self Assessment helpline if you’ve missed your payment date or you cannot use the online service. You do not need to contact HMRC if you have set up a payment plan online.
