Question: what is an ot 1 tax code?
Answer: 0T, 0T-W1 and 0T-M1 Nearly everyone is entitled to a tax-free personal allowance, which means that a certain amount of your earnings each year are paid to you without being taxed. However, 0T tax codes mean that you do not receive any personal allowance with this employment. Instead, you pay tax on all of your income.
