Heddiw, cyhoeddwyd adroddiad gan Brifysgol Bangor, *Asesiad Technegol o’r potensial i Dreth Gwerth Tir leol yng Nghymru,* ar wefan Llywodraeth Cymru. Comisiynodd Llywodraeth Cymru yr adroddiad fel rhan o ystod o waith ymchwil i drethi lleol yng Nghymru.

Ym mis Mawrth 2019, cafodd Prifysgol Bangor ei chomisiynu gan Lywodraeth Cymru i ymchwilio i’r posibilrwydd o weithredu system trethi lleol yng Nghymru a fyddai’n seiliedig ar werth tir, yn hytrach na’r system bresennol sy’n gyfuniad o werth tir ac eiddo, yn ogystal â ffactorau megis cyfansoddiad yr aelwyd. Mae gwahanol systemau trethi gwerth tir ar waith eisoes mewn rhannau eraill o’r byd, ac fe’u gwelir fel ffordd deg a blaengar o godi treth ar gyfer gwasanaethau cyhoeddus. Fodd bynnag mae’n ymddangos y byddai’n dipyn o her symud yn ymarferol o’r systemau presennol ar gyfer codi trethi lleol i system treth gwerth tir leol.


Bwriad Llywodraeth Cymru wrth ymchwilio i systemau amgen ar gyfer codi trethi lleol yw dod o hyd i ddulliau teg o godi refeniw sefydlog ar gyfer gwasanaethau, gan ystyried unrhyw ganlyniadau buddiol eraill lle bo hynny’n bosibl. 


Mae Prifysgol Bangor wedi ymchwilio i ddichonoldeb treth gwerth tir fel cysyniad a fyddai’n cael ei weinyddu’n lleol, y byddai refeniw’r dreth hon yn disodli’r refeniw tebyg a godir drwy’r systemau trethi lleol presennol, y dreth gyngor ac ardrethi annomestig. Nid yw treth gwerth tir yn y cyd\-destun hwn yn cael ei hystyried fel ffordd o godi trethi lleol ychwanegol a fyddai’n gallu codi tipyn mwy neu lai o gyllid refeniw nag sy’n cael ei godi ar hyn o bryd, ac nid yw’n cael ei hystyried chwaith fel cysyniad cenedlaethol.


Mae adroddiad Prifysgol Bangor yn darparu asesiad cychwynnol o dreth gwerth tir leol yng Nghymru, gan nodi’r gwaith pellach y byddai angen ei wneud i brofi’r dull gweithredu hwn yn drwyadl. Un o’r canfyddiadau pwysig y dylid ei ystyried yn y dyfodol yw’r buddsoddiad y byddai angen ei wneud i fodloni’r gofynion gwybodaeth manwl a allai fod yn sail i dreth o’r fath, gan gynnwys cofnodion tir cynhwysfawr (*cadastres*) a chyfundrefnau prisio cadarn a thrylwyr.


Rwy’n falch bod Prifysgol Bangor, fel rhan o’i hymchwil, wedi gallu datblygu model ystadegol rhagbaratoawl ar gyfer amcangyfrif set o werthoedd tir. Ni fu cais cyn hyn i ddarparu manylion o’r fath yn y llenyddiaeth ar gyfer Cymru, ac mae wedi galluogi Bangor i bennu cyfraddau treth gwerth tir posibl a fyddai’n codi cyllid refeniw sy’n cyfateb yn fras i’r hyn a godir drwy’r systemau trethi lleol presennol. Fodd bynnag un wers allweddol a ddysgwyd o’r gwaith modelu hwn yw ei bod yn llawer mwy heriol amcangyfrif gwerth ar gyfer tir annomestig nag ar gyfer tir domestig. 


Mae’r adroddiad a gyhoeddwyd heddiw yn cyfrannu at ein dealltwriaeth o ddiwygiadau y gellid eu cyflwyno yn y dyfodol, ond byddai angen gwneud llawer mwy o waith ynglŷn â goblygiadau polisi a goblygiadau ymarferol pob syniad. Er enghraifft, byddai angen ystyried a fyddai’n bosibl datblygu opsiynau sy’n cefnogi amcanion polisi ehangach megis datgarboneiddio a threchu tlodi, ac yn bwysig iawn, sut y gellid cynnal y cysylltiad rhwng trethdalwyr lleol a’r gwasanaethau lleol a ddarperir ar eu cyfer.


Un llinyn o waith yw’r ymchwil hon o fewn rhaglen ehangach ar gyfer diwygio trethi lleol a system gyllid llywodraeth leol. Cyhoeddais wybodaeth am hynt y rhaglen waith ar 5 Tachwedd, a cheir mynd at yr wybodaeth honno drwy glicio ar y ddolen ganlynol:

Today, a report by Bangor University, A Technical Assessment of the Potential for a Local Land Value Tax in Wales, has been published on the Welsh Government website. The report was commissioned by the Welsh Government as part of a suite of research relating to local taxation in Wales.


In March 2019, the Welsh Government commissioned Bangor University to explore whether local taxes in Wales could be based on the value of land, as an alternative to the current position which is an amalgamation of both land and property value, as well as factors such as household composition. Land value tax (LVT) exists in some parts of the world in various forms, and is purported to be a fair and progressive way of raising taxes for public services. However, the practical viability of moving from existing forms of local taxation to a local LVT has been found to be challenging.


The objective of the Welsh Government in exploring alternative forms of local taxation is to examine how to raise stable revenue for local services in the fairest way, with other advantageous outcomes considered where possible. 


Bangor University has explored the feasibility of LVT as a locally\-administered concept, replacing similar revenues to those that are currently raised through the existing local taxes, council tax and non\-domestic rates. LVT in this context has not been considered as an additional form of local taxation, raising significantly more or less revenues than currently, or as a national concept.


Bangor University’s report provides an initial appraisal of a local LVT in Wales, identifying further work that would be required to fully test this approach. An important finding for future consideration is the investment necessary to meet the detailed information requirements on which such a tax could be based, including comprehensive cadastres of land and robust mechanisms for valuation. 


I am pleased that within the scope of the research, Bangor University has been able to construct a preliminary statistical model to estimate a set of land values.  Such detail has not been attempted before in the literature for Wales and it has enabled Bangor to determine potential tax rates, at which LVT would need to be levied to raise revenues broadly equal to the current systems of local taxation. However, a key lesson learned from the modelling work is that it is significantly more challenging to estimate land values for non\-domestic uses than it is for domestic. 


The report published today makes a contribution to our understanding of possible future reforms but much more work would be needed regarding the practical and policy implications of each idea. For example, whether various options could be designed in such a way to support wider policy objectives such as decarbonisation and tackling poverty, and crucially, how the link between local taxpayers and the local services they receive can be maintained. 


This research is one strand of work within a broader programme of reforms to local taxation and the wider local government finance system. Read the progress update on the work programme I published on 5 November.
