Rydym wedi cytuno â Llywodraeth y DU i estyn oes ein parthau buddsoddi yn y De-ddwyrain a'r Gogledd-ddwyrain o bump i ddeng mlynedd. Bydd pob un yn cael pecun ariannu o £160m o 2024 tan 2034, i'w ddefnyddio'n hyblyg fel gwariant a chymhellion treth, yn amodol ar y cynigion y bydd Lywodraeth Cymru a Llywodraeth y DU yn eu cyd-ddylunio a'r cynlluniau cyflawni y cytunir arnynt. Fel rhan o becyn o gymhellion treth, bydd parthau buddsoddi yng Nghymru yn cael cadw 50% o'r ardrethi annomestig ychwanegol a wneir yn yr ardaloedd dynodedig i'w hailfuddsoddi yn y parth buddsoddi.
We have agreed with the UK Government that both investment zones in South-East and North-East Wales will be extended from five years to 10. Each will be provided with a £160m funding envelope from 2024 to 2034, which can be used flexibly between spending and tax incentives, subject to ongoing co-design of the proposals and agreement of delivery plans with the Welsh Government and the UK Government. As part of a package of tax incentives, investment zones in Wales will be able to retain 50% of additional non-domestic rates generated within designated areas for reinvestment in the investment zone.
