About this form

IR23BS is used to apply for a tailored tax code or, when using the WT tax code, a special rate of tax for schedular payments.

Before applying

Complete the income estimates and the sections relevant to the income or payer concerned, then sign the declaration. Use a separate application where the tailored rate is needed for another employer.
