Bills

New laws for Wales, explained: what each Bill would do, who it would affect, what Members have said about it, and what happens next.

How a Bill becomes law in Wales

A Bill is a proposed new law. Most come from the Welsh Government, but any Member can propose one. It goes through four stages in the Senedd, then becomes law when the King signs it.

  1. 1. Stage 1A committee looks at the Bill's general principles, then the Senedd votes on them.
  2. 2. Stage 2A committee considers amendments.
  3. 3. Stage 3The whole Senedd considers amendments.
  4. 4. Stage 4The Senedd votes to pass the Bill.
  5. 5. Royal AssentThe Bill becomes an Act of Senedd Cymru.

Some UK Parliament laws also change things the Senedd is responsible for, like health or education in Wales. The Senedd then votes on whether it agrees. This is called legislative consent.

What it would do

The Welsh Government says the Bill would make technical and administrative changes to the Welsh tax laws that already exist. It says these would make the tax system clearer and more effective. The Minister says the Bill would let the Welsh Revenue Authority share information with local authorities, withhold some repayments during an inquiry, and carry out some landfill inspections without prior approval. Contributions: [1][2][3][4]

Who it would affect

It would mainly affect taxpayers and their advisers who deal with the Welsh Revenue Authority, local authorities that would receive shared information, and businesses that could face landfill inspections. Contributions: [1][2][3][4]

What has been said

  • Elin Jones (Plaid Cymru), the Finance Minister, says the powers are proportionate and respond to gaps raised by the Welsh Revenue Authority and taxpayers' representatives. She says unannounced landfill inspections already exist in England and Scotland. Contributions: [1][2]
  • Cai Parry-Jones (Reform UK) says only nine people responded to the consultation. He is concerned that the Bill removes tribunal approval for some landfill inspections, and asks what evidence shows this is necessary. Contributions: [1]
  • Huw Thomas (Welsh Labour) welcomes the aim of collecting devolved taxes fairly and efficiently. He asks for assurance that information shared with local authorities will be shared only when essential, and for practical examples. Contributions: [1][2]
  • Elin Jones says data sharing would be limited to specific purposes and must follow existing data protection law. She gives the planned tourism levy as an early example of why sharing matters. Contributions: [1]
  • John Clark (Reform UK) notes that withholding repayments during an inquiry could cause cash flow problems for taxpayers. He asks for published service standards and reporting on how long repayments are withheld. The Minister called this a sensible point and said she would take it away. Contributions: [1][2]
  • Iain McIntosh (Reform UK) says the impact assessment shows £422,000 of costs against £2.6 million of benefits, much of it staff time freed up. He asks how much would be real savings. The Minister says costs and benefits are small. Contributions: [1][2]

What happens next

A committee of Members is gathering evidence on the Bill and will report. Then all Members vote on whether they agree with what it sets out to do. If they don't, the Bill goes no further.
