Check you actually overpaid
You overpay when you stop working mid-year. Your tax was calculated as if you would earn your salary all year. Do a rough check. Compare the total tax you paid with the tax due on your actual income. Use the year's bands. If you started a new job soon after, the P45 usually sorts it automatically. A P50 is for people who stopped working entirely.

- Before You Go —
Wait until you have your P45
You need the P45 from your employer, who must give it when you leave. It includes parts 1A, 2, and 3 from your employer. If they never sent it, ask payroll first. After that, HMRC can find your record from your NI number alone. But the P45 makes everything faster.

HMRC recalculate your tax for the whole year. They use your actual income. If you are owed money, they repay it. This is typically within 4 weeks online. It takes longer by post. If you underpaid instead, they usually collect it through next year's tax code. They do not usually demand it immediately.
