keep The Income Tax (Indexation) Order 2018
Routine fiscal indexation order for tax year 2019-20 that updates various Income Tax Act 2007 allowance amounts: blind person's allowance (£2,450), married couple's minimum amount (£3,450), married couple's allowance for pre-2005 marriages (£8,915), married couple's allowance for post-2005 marriages/civil partnerships (£8,915), and adjusted net income limit (£29,600).
This is a mechanical inflation adjustment that preserves the real value of existing statutory allowances. Without indexation, fiscal drag would effectively increase taxes on blind persons and married couples, punishing them for inflation rather than real income growth. While allowances themselves represent government intervention, their sudden deflation through non-indexation would create immediate, foreseeable harm to identifiable groups this Parliament has already decided to assist.
