Yes, you can start fresh this tax year. I also suggest contacting the HMRC to verify if you have to file a zero wage form.
To help stay on top of all the changes that come into effect every April, we've combined a summary of the key facts and figures. Check out the Payroll Tax Year Changes 2020/2021 guide for complete details.
It outlines all the changes on thresholds for personal tax allowance, SRIT, employment allowance, statutory payments, and student & postgraduate loans.
Let me know in the comment box if you have any clarifications or concerns. I’ll be right here to help and make sure you’re taken care of. Have a great rest of the day.
