    • After we have received your notification, we will send you a new Coding Notice. This will contain information about the allowances you are entitled to, and any income you receive which is not taxed at source. It will also show your calculated Tax-free Coding Balance, (which is the amount your employer will deduct from your salary figure, after any payments have been made to an approved pension fund, to calculate the figure on which tax needs to be deducted).
    • Your new employer will also receive notification of your Tax-free Coding Balance so that they can calculate the tax you need to pay tax on your salary.
