I have noticed exactly the same thing when I have submitted my self assessment this time around. During the last tax year I paid £398 and my student loan was finally paid off in full. However on my self assessment it has added another £2500. What are the contact details for your Self Assessment team? When I went to make the payment for tax owed I took off the amount that has been overcharged - the student loan was paid in full in May 2021. Will this cause any complications? Thank You
