If I request a financial hardship loan, how do I pay this back?

Any financial hardship loan awarded will be deducted in full from your next salary payment, even if your tax code remains at D0. If your tax code has not been rectified, then you will have to re-apply for a hardship loan each month until it is rectified. NES reserves the right to reject an application if they feel you are not attempting to resolve the issue with HMRC.
