Welsh Budget 2027/28: What to Watch For (No Announcement Yet)
The Welsh Budget for 2027/28 has not been published — no draft, no rates, no dates. Here's how Welsh devolved income tax actually works today, the timeline to expect, and what to watch for.
Why this article exists — and what it deliberately does not do
Search interest in "Welsh Budget 2027/28" typically spikes ahead of any actual announcement, as taxpayers, payroll teams and advisers try to plan ahead. Unfortunately, there is nothing to report yet: no draft Welsh Budget for 2027/28 has been published, and no Welsh Rate of Income Tax (WRIT) decision for that year exists. Given the Welsh Budget's usual timeline (explained below), a 2027/28 draft would not typically be expected until around autumn 2026 at the earliest, with the final Budget following in the Senedd in early 2027.
So rather than guess, this piece does two useful things instead:
- Explains exactly how Welsh devolved income tax works today, using only current, confirmed figures.
- Sets out what to watch for when the 2027/28 process eventually starts, so you know where to look and what questions matter.
Unless the Senedd changes course, the pattern that has held since devolution began is the single most useful piece of context for thinking about 2027/28 — but it is a pattern, not a promise.
How the Welsh Rate of Income Tax (WRIT) actually works
Income tax devolution to Wales began in April 2019. It works differently from Scotland's system, and the difference matters:
- The UK Government reduces each of the three main income tax rates — basic, higher and additional — by 10 percentage points for anyone classed as a Welsh taxpayer.
- The Welsh Government then sets its own Welsh rate, which is added back on top of the reduced UK rate.
- The bands and thresholds stay identical to rUK (England and Northern Ireland) — Wales has never used separate bands, unlike Scotland.
- Only non-savings, non-dividend income (mainly earnings, self-employment profits and pension income) is affected. Savings interest and dividends are taxed at UK-wide rates regardless of WRIT.

Income tax calculatorThe mechanism, using current confirmed rates
The table below shows the WRIT mechanism using the rate that has applied in every tax year since devolution began — the UK rate reduced by 10 points, with the Welsh Government's own rate added back to reconstruct the rate a Welsh taxpayer actually pays. These are current, settled figures, not a 2027/28 forecast.
| Band | Standard rUK rate | UK rate minus 10p (the "residual" rate) | Welsh rate added by Welsh Government | Combined rate paid by Welsh taxpayers |
|---|---|---|---|---|
| Basic rate | 20% | 10% | 10p | 20% |
| Higher rate | 40% | 30% | 10p | 40% |
| Additional rate | 45% | 35% | 10p | 45% |
Because the Welsh Government has consistently set its rate at 10p in every band, every year, the combined rate has landed exactly on the rUK rate every single year since 2019/20. That is a choice the Senedd has made annually through the Budget process — it is not a structural guarantee, and it could change in a future Budget, including potentially 2027/28. Nothing in the current framework prevents a future Welsh Government from setting a different rate; it simply hasn't happened yet.
Who is affected — Welsh taxpayer status
HMRC decides who is a "Welsh taxpayer" based on where you live, not where you work or where your employer is based. If your main home was in Wales for more of the tax year than anywhere else in the UK, HMRC applies a 'C' prefix to your tax code (for example, C1257L instead of 1257L). Employers and pension providers apply the correct rate automatically through PAYE once HMRC has updated your code, but if you've recently moved into or out of Wales, it's worth checking your payslip or P60 to confirm the prefix is correct.

Scotland's system is often confused with Wales's, but the two are structurally different:
| Feature | Wales (WRIT) | Scotland |
|---|---|---|
| Rates devolved | Partially — 10p of each band | Fully — Scottish Parliament sets all rates |
| Bands/thresholds | Same as rUK | Fully separate Scottish bands |
| Number of bands | 3 (basic, higher, additional) | 6 (starter, basic, intermediate, higher, advanced, top) |
| Divergence from rUK so far | None to date | Diverged in most years since 2018 |
| Collected by | HMRC | HMRC |
Scotland has used its fuller devolved powers to set a materially different rate and band structure from rUK in most years since 2018. Wales, by contrast, has a narrower devolved lever — just the rate, not the bands — and has chosen not to use it to diverge, at least so far.

Understanding the usual cadence helps you judge when a genuine 2027/28 announcement should actually appear, and helps filter out premature speculation:
- Autumn (often December) — the Welsh Government publishes a draft Budget for the following financial year, including any proposed WRIT rate. This draft is subject to negotiation and can be amended before the final vote.
- Scrutiny period — Senedd committees examine the draft Budget, taking evidence and proposing amendments.
- Early in the new year — the Senedd votes on and agrees the final Budget, including the confirmed WRIT rate for the coming tax year.
- 6 April — the new tax year begins, and the confirmed WRIT rate takes effect for Welsh taxpayers via PAYE and Self Assessment.
Applying that pattern to 2027/28: a draft would realistically not appear before autumn 2026 at the earliest, with the Senedd's final vote following in early 2027, ahead of the tax year starting 6 April 2027. As of this article's publication in July 2026, that process has not started, and no proposals had been published.
What to actually watch for
When the Welsh Budget process for 2027/28 does eventually start, the genuinely useful questions to ask are:
- Does the Welsh Government propose keeping WRIT at 10p across all three bands (maintaining parity with rUK, as in every year to date), or does it propose diverging for the first time?
- Are there any changes to how Welsh taxpayer status is determined, or any transitional arrangements announced?
- Does the UK Government's own Autumn Budget or Spring Statement change the rUK basic, higher or additional rates — because any rUK rate change automatically flows through to the "residual" rate that WRIT sits on top of, even if the Welsh rate itself stays at 10p?
- What does the Office for Budget Responsibility or Welsh Government's own fiscal forecast say about the revenue implications of maintaining vs. changing the rate?
None of these questions can be answered yet. This article will be updated once an official draft Budget for 2027/28 is published by the Welsh Government.
What not to do with this article
Do not use any number in this piece as a 2027/28 prediction. Every rate shown here is the current, confirmed rate that has applied consistently since 2019/20, presented purely to explain the WRIT mechanism. If you are trying to plan finances for the 2027/28 tax year specifically, the only responsible approach right now is to:
- Use current confirmed rates for any planning that assumes continuity (which has been the pattern to date), while flagging that assumption clearly.
- Check gov.wales, the Welsh Revenue Authority and gov.uk directly once a draft Budget is published, rather than relying on secondary summaries.
- Treat any pre-announcement commentary — including this article — as background on mechanism and process, not as a rate forecast.

Frequently asked questions
Has Wales changed its income tax rates?
No. Since the Welsh Rate of Income Tax (WRIT) began in April 2019, the Welsh Government has set its rate at exactly the level needed to keep total Welsh income tax equal to the rest of the UK (rUK) rate in every year to date, based on the current settled tax year at time of writing. This is a deliberate, published policy choice by Welsh ministers, not an automatic default — the Senedd could diverge in any future Budget, but as things stand Welsh and rUK taxpayers pay identical income tax. Bands and thresholds are also unchanged from rUK, which is different from Scotland's approach.
What might change for the 2027/28 Welsh Budget?
Nobody knows yet, and no proposals had been published as of writing (July 2026). The Welsh Budget for a given financial year is normally published in outline in autumn/December of the preceding year and finalised by the Senedd in the new year, so a 2027/28 draft would not typically appear until around autumn 2026 at the earliest, with the final Budget following in early 2027. Any figures, rates or band changes you see attributed to 2027/28 before an official Welsh Government publication should be treated as speculation, not fact. This article deliberately avoids inventing any such numbers.
What is the Welsh Rate of Income Tax (WRIT)?
WRIT is the mechanism that partially devolves income tax to Wales. The UK Government reduces each of the three main England/Wales/Northern Ireland income tax rates — basic, higher and additional — by 10 percentage points for Welsh taxpayers. The Welsh Government then sets a Welsh rate, which is added back on top of the reduced UK rate to produce the rate a Welsh taxpayer actually pays. If the Welsh rate is set at 10p, the combined rate matches the rUK rate exactly, which is what has happened every year since 2019/20.
Does Wales have different tax bands from England?
No — this is the key structural difference from Scotland. Wales uses the same income tax bands and thresholds as England and Northern Ireland (personal allowance, basic rate band, higher rate threshold, additional rate threshold). Only the rate percentage is partially devolved via WRIT, and only for non-savings, non-dividend income (mainly employment and self-employment earnings, plus pension income). Scotland, by contrast, has fully separate bands as well as separate rates, which is why Scottish and Welsh devolved income tax work quite differently in practice.
Who counts as a Welsh taxpayer for income tax purposes?
HMRC determines Welsh taxpayer status primarily by where you live, not where you work. If your main home is in Wales for more of the tax year than anywhere else in the UK, you're a Welsh taxpayer and your tax code carries a 'C' prefix (e.g. C1257L). Employers and pension providers apply the Welsh rate automatically once HMRC has updated the tax code — you don't need to do anything separately, but it's worth checking your payslip or P60 tax code prefix if you've recently moved into or out of Wales.
Does WRIT affect savings interest or dividends?
No. WRIT only applies to non-savings, non-dividend income — essentially employment income, self-employment profits, pension income and property income taxed as income. Savings interest and dividend income for Welsh taxpayers are taxed at the same UK-wide rates and bands that apply to everyone in England, Wales and Northern Ireland, regardless of WRIT. This is the same carve-out that applies under the Scottish income tax system.
When is the Welsh Budget usually published?
The Welsh Government typically publishes a draft Budget in the autumn, often in December, covering the following financial year. The Senedd (Welsh Parliament) then scrutinises and votes on a final Budget, usually agreed in the early part of the new year, well ahead of the financial year starting on 6 April for tax purposes (and 1 April for most Welsh Government spending). Because WRIT rate decisions form part of this annual Budget process, any change to Welsh income tax rates would be announced through this same timeline — not sprung on taxpayers mid-year.
Where can I find the official confirmed Welsh tax rates?
Always check gov.wales for the Welsh Government's own Budget documents, the Welsh Revenue Authority (WRA) for devolved tax administration (Land Transaction Tax and Landfill Disposals Tax, which the WRA collects — WRIT itself is collected by HMRC alongside rUK income tax), and gov.uk's dedicated Welsh income tax page for the current confirmed rate. These are the only sources that should be treated as authoritative; press speculation or third-party prediction articles ahead of an official announcement are not a substitute.
Will pension and savings calculators need updating for 2027/28?
Only once the Welsh Government confirms its rate for that year, and only if it actually diverges from rUK rates — which has not happened in any year since devolution began. Until an official rate is published, calculators correctly continue to use the current, settled tax year's confirmed WRIT rate (currently equal to the rUK rate), because applying an unconfirmed future rate would produce inaccurate results for anyone using the tool today.
