Self Employment Grant Calculator

We have provided an easy to use calculator designed to help you estimate the third grant that may be available to you under the Self-Employment Income Support Scheme (SEISS). Scroll down to access our handy tool.

In the recent Winter Economy Plan, the Government announced that a third grant would be available under the Self-employment Income Support Scheme. This grant covers the period from November 2020 to January 2021, and the level of grant has been increased to support businesses during the new coronavirus lockdown measures.

In addition to the calculator below, we have detailed all of the financial support available to the Self Employed here.

To help you understand what is available to you and access the money you need to see you through this challenging time, we’re offering FREE telephone or video consultations. Call us today on 0203 325 9825 or enquire online.

In order to be eligible for the third grant under the Government’s Income Support Scheme you must:

  • Have traded in the tax year 2018/19 and submitted your Self-Assessment tax return on or before 23 April 2020 for that year
  • Declare that you are currently actively trading and intend to continue to trade and either:
