NRE is used when calculating the maximum that can be paid into a personal pension scheme. These are limited to a certain percentage of your net relevant earnings.
Net rents
Gross rents received less payments for charges and services that would normally be borne by the tenant, but are, in fact, borne by you (for example, council tax, water and sewerage rates etc).
