Importantly, farm business income does not include other sources of household income from outside the farm business (such as other employment of the farmer or spouse outside of the farm).
Mae’n bwysig cofio nad yw incwm busnesau ffermio yn cynnwys ffynonellau incwm eraill o'r tu allan i'r busnes ffermio (megis swyddi eraill y ffermwr neu briod y ffermwr y tu allan i'r fferm).
