Chancellor Rachel Reeves will present Labour’s first budget for 14 years to MPs in the House of Commons on Wednesday. But what might it mean for Wales? Here are some things to look for.
1. Public services
2. Tax rises
To help pay for all this, the UK government says tax rises will be needed. Labour’s election manifesto promised not to increase taxes on "working people" - ruling out rises in VAT, National Insurance (NI) or income tax.
So there has been a lot of speculation about what might go up.
Small businesses are often described as the backbone of the Welsh economy and many are concerned about moves to increase employer’s NI contributions.
They include Kristian Cuffin, owner of Cuffed in Coffee in Holyhead, who said the change could lead to "tough decisions" for his business including "reducing staff hours, holding off on hiring new staff and cutting back on expansion plans".
The FSB in Wales, which speaks on behalf of small businesses, is calling on the Treasury to increase the Employment Allowance which allows them to reduce their NI costs.
There is also speculation that the Chancellor could increase fuel duty.
Plaid Cymru warn this would have a "disproportionate" impact on rural Wales.
"Our part of the world depends very much on the car because of a lack of public transport", said Ben Lake MP.
3. Winter Fuel Payments
Wales has a larger proportion of older people than elsewhere in the UK (22% are over 65 compared to an average 19%).
So it’s no surprise there’s been a fair bit of disquiet from different quarters over the decision to means test the winter fuel payment.
The leader of the Welsh Conservatives Andrew RT Davies, has said the policy is "unforgivable" and called on Labour to "keep pensioners warm this winter".
The older people’s commissioner for Wales is also urging a "rethink"
4. Coal tip safety
There are more than 2,500 disused coal tips in Wales, including 360 deemed highest risk.
Finance Secretary Mark Drakeford has said he has been "in conversations" with the Treasury about funding to make these safe and is "hopeful that we will see a movement in that direction" if not in this Budget then the spring statement.
