Emergency Tax Refund Calculator
On an emergency tax code? Estimate how much you have overpaid and could claim back — enter your salary, code and how long you have been on it.
Estimate only; your actual refund depends on your payslips. Not tax advice.
Quick answer
On an emergency BR or 0T code you get no tax-free Personal Allowance, so you are over-taxed by roughly £209 a month (20% of the £1,048 monthly allowance). Over three months that is about £630, which you can reclaim from HMRC — unless your allowance is being used on another job.
