Bydd datganoli pwerau trethi'n caniatáu i Lywodraeth Cymru ddatblygu dull gweithredu cryfach o ran trethi canolog a lleol yng Nghymru, gan sicrhau ei bod yn gallu mynd i'r afael yn well ag anghenion a blaenoriaethau dinasyddion a busnesau.


Byddai treth ar dir gwag yn helpu i gymell datblygwyr i fwrw ymlaen â datblygiadau segur i helpu i ddarparu tai diogel a fforddiadwy o ansawdd uchel.


A hithau'n siarad mewn dadl yn y Senedd bydd y Gweinidog yn pwysleisio'r angen am system ddiwygiedig o ddatganoli trethi sy'n cyflawni gwell canlyniadau i bobl Cymru.


Dywedodd Rebecca Evans, y Gweinidog Cyllid a Llywodraeth Leol:



> “Dechreuon ni drafodaeth genedlaethol yn 2017 ynghylch sut y gallai pwerau trethi newydd gynnig cyfleoedd i'n helpu i wireddu ein huchelgeisiau i Gymru. Fwy na phedair blynedd yn ddiweddarach dydy'r cyfleoedd hynny ddim ar gael inni o hyd. Dydy'r broses ddim yn addas i'w diben a rhaid ei gwella.
> 
> 
> “Mae achos cryf dros ddatganoli treth ar dir gwag, o gofio ei fod yn cyd\-fynd â phwerau datganoledig sy'n bodoli eisoes a'i gwmpas cymharol gul. Neilltuwyd dwy flynedd o waith i sicrhau bod gan Lywodraeth y DU'r wybodaeth yr oedd arni ei hangen i ystyried yr achos hwn. Cytunwyd mai mater i Lywodraeth Cymru oedd gwneud unrhyw benderfyniadau polisi ynghylch sut y byddai unrhyw dreth ddatganoledig newydd yn gweithio, ac mai mater i'r Senedd fyddai penderfynu a ddylid pasio unrhyw dreth mewn cyfraith.
> 
> 
> “Serch hynny, ac er bod gwybodaeth helaeth eisoes wedi'i darparu, mae Llywodraeth y DU'n dal i ofyn am ragor o wybodaeth am sut y mae'r dreth yn gweithredu. Buom yn gweithio'n ddidwyll gyda Llywodraeth y DU ond nid yw'n briodol iddi geisio penderfynu ar bolisi datganoledig nac ymwneud â materion sy'n fater i Lywodraeth Cymru a'r Senedd."


Mae amcangyfrifon tai'n dangos bod angen 7,400 o gartrefi ychwanegol am y pum mlynedd nesaf.


Ychwanegodd y Gweinidog:



> “Dydy treth ar dir gwag ar ei phen ei hyn yn ateb i'r argyfwng tai, wrth gwrs, ond fe allai helpu i gyflwyno datblygu amserol. Fel y mae ar hyn o bryd mae tirfeddannwr sy'n dal gafael ar dir a nodwyd ar gyfer datblygiadau'n arwain at elw preifat a chost gyhoeddus. Byddai treth ar dir gwag yn cymell gwaith datblygu ac yn creu cartrefi i bobl.”


Mae'r Gweinidog wedi ysgrifennu at Ysgrifennydd Ariannol newydd y Trysorlys i dynnu sylw at bwysigrwydd bwrw ymlaen â'r cais am bwerau ar gyda'r treth ar dir gwag.

The devolution of tax powers will allow the Welsh Government to develop a strengthened approach to central and local taxation in Wales, ensuring it is better able to tackle the needs and priorities of citizens and businesses.


A vacant land tax would help to incentivise developers to progress stalled developments to help provide high quality, safe and affordable housing.


Speaking in a debate in the Senedd the minister will stress the need for a reformed system of devolving taxes which delivers better outcomes for the people of Wales.


Rebecca Evans, Minister for Finance and Local Government, said:



> “We began a national debate in 2017 about how new tax powers could provide opportunities to help us realise our ambitions for Wales. More than 4 years later those opportunities are still not available to us. The process is not fit for purpose and must be improved.
> 
> 
> “There is a compelling case for the devolution of vacant land tax, given its alignment with existing devolved powers and relatively narrow scope. Two years of work went into ensuring the UK government had the information it needed to consider this case. We agreed it was for the Welsh Government to make policy decisions about how any new devolved tax would operate, and for the Senedd to decide whether to pass any new tax into law.
> 
> 
> “Despite this, and despite extensive information already being provided, the UK government continues to ask for yet more information on the operation of the tax. We worked with the UK government in good faith but it is not appropriate for it to attempt to determine devolved policy or get involved in matters which are rightly for the Welsh Government and the Senedd.”


Housing estimates show that an additional 7,400 homes are needed per year for the next 5 years.


The minister added:



> “A vacant land tax alone is not the solution to the housing crisis, of course, but could help bring forward timely development. As it stands a landowner holding onto land identified for developments leads to a private gain and a public cost. A vacant land tax would incentivise development and create homes for people.”


The minister has written to the new Financial Secretary to the Treasury to highlight the importance of making progress with the request for powers for a vacant land tax.
