Tax Code 1100L Explained

What does this code mean?

1100L means your tax-free amount is £11,000. HMRC has reduced your Personal Allowance by £1,570 from the standard. This reduction is usually to collect tax on untaxed income or benefits in kind, or to recover a tax underpayment from a previous year through your tax code.

Who gets this code?

Employees with significant benefits in kind, or those with underpayment adjustments from HMRC.
