The fiscal impact and economic benefits of immigration in Britain
“Immigrants are not a net fiscal burden on the UK. Many groups of immigrants contribute at least as much as the UK-born population, and in several cases, more.”

December 2025: In Britain, public and political debate about immigration is too often about the cost to the public purse and less about its economic, social and cultural benefits. The Migration Advisory Committee (MAC), the UK government’s independent body tasked with analysing migration policy, has published a comprehensive review of the fiscal impact of immigration. Its findings do not support the caricature of migrants as a net burden. Instead, the report paints a more complex and, in many respects, more positive picture of how immigration contributes to the UK economy and public finances.
The report’s aim
While the report’s authors ask a straightforward question: “Do migrants contribute more in taxes than they receive in public spending?”, in practice, the answer depends on multiple variables, age, skills, earnings, length of stay, family composition and the wider state of the economy. Rather than producing a single headline number, the report analyses fiscal impact over time and across migrant groups. This approach is significant. The MAC repeatedly cautions against short-term snapshots, arguing that fiscal effects should be assessed over the life cycle, not year by year.
Immigration is not a drain on public finances.
The MAC’s analysis aligns with estimates published elsewhere in the UK’s economic debate. For example, analysis cited by the Financial Times suggests that migration delivers a net boost of around £47 billion to the UK economy, once higher output, tax contributions and labour market effects are taken into account.
While methodologies differ, this figure helps contextualise the MAC’s more cautious conclusion: even under conservative assumptions, immigration does not weaken the public finances. One of the report’s most consistent messages is that immigrants, taken as a whole, are not a net fiscal burden on the UK. Many groups of immigrants contribute at least as much as the UK-born population, and in several cases, more.
This is driven largely by demographics. Immigrants are, on average, younger and more likely to be of working age than the UK-born population. That means they are more likely to be paying income tax, national insurance and VAT, and less likely to be drawing on age-related public spending such as pensions and healthcare.
The MAC also notes that recent cohorts of migrants are more likely to be in employment than earlier ones, reflecting changes in migration policy and the structure of the UK labour market.
Skilled immigrants contribute substantially to Britain
The report is particularly clear on the fiscal contribution of higher-skilled migrants. Immigrants in professional, technical and health-related roles tend to make a strongly positive net contribution, due to higher earnings and sustained labour market participation.
This is not limited to traditionally high-paid sectors such as finance or technology. Health and social care workers, often discussed primarily in terms of labour shortages, also make a fiscal contribution, especially when their role in sustaining the wider workforce is taken into account.
The MAC is careful to stress that fiscal impact should not be the sole criterion for migration policy. Nevertheless, its analysis undermines claims that immigration represents a cost to taxpayers.
Lower-paid immigrants are essential to the economy
Where the report is more cautious is in its assessment of immigrants in lower-paid sectors. These groups tend to make a smaller net fiscal contribution, and in some cases, a neutral one. However, the MAC strongly warns against drawing simplistic conclusions.
First, lower-paid immigrants often work in sectors that are essential to the functioning of the economy, including food production, logistics, hospitality and care. Second, the fiscal impact is not static. Earnings typically rise over time, and so does tax contribution.
Most importantly, the committee argues that fiscal accounting alone cannot capture the broader economic value of migration, including its role in sustaining services, keeping prices down, and enabling higher participation among UK-born workers.
Immigration and Britain’s ageing society
One of the report’s most politically relevant sections concerns the UK’s ageing population. The MAC notes that, without immigration, the ratio of workers to retirees would decline more sharply, placing greater strain on public finances.
While immigration is not a permanent solution to demographic ageing, as immigrants themselves grow older, it slows the process and eases fiscal pressure in the medium term. In this sense, immigration acts as a stabilising force rather than a cure-all. This finding is especially relevant as the UK grapples with rising healthcare costs and long-term pressures on the state pension system.
Immigrants use fewer public services
The report also addresses a frequent political claim: that immigrants disproportionately use public services. The evidence presented by the MAC survey does not support this assertion. Working-age immigrants tend to use fewer public services than the UK-born population, particularly when adjusted for age. Where there are localised pressures, for example in housing or schools, the MAC emphasises that these are distributional and policy issues, not evidence of a negative national fiscal impact.
In other words, the problem is not immigration per se, but whether public investment keeps pace with population change.
The report’s limits
The MAC is explicit about the limits of its analysis. Fiscal impact is not the same as economic growth, productivity or social cohesion. Nor does a positive fiscal contribution automatically justify unlimited migration.
However, the authors are equally clear that arguments portraying immigration as a major cause of Britain’s fiscal challenges are not grounded in evidence. The UK’s public finance pressures stem primarily from structural factors: ageing, low productivity growth, and policy choices around taxation and spending.
Key figures: migration and the UK economy
• Estimated net economic contribution of migrants: ~£47 billion (Financial Times–cited analysis)
• Employment rate (recent migrant cohorts): Comparable to or higher than the UK-born working-age population.
• Age profile: Migrants disproportionately of working age, reducing per-capita spending on pensions and age-related healthcare.
• Fiscal impact overall: Neutral to positive, depending on skills, earnings and length of stay.
The £47 billion figure
The widely cited £47 billion boost reported by the Financial Times is not a single tax-transfer calculation, but a broader estimate of immigration’s impact on the UK economy. In simplified terms, it reflects three main channels:
• Higher economic output: By increasing the size of the workforce, migration raises overall GDP, particularly in sectors facing labour shortages.
• Net tax contribution: Working-age migrants pay income tax, national insurance and VAT while making comparatively lower use of age-related public spending.
• Labour market effects: Migrants enable businesses to expand and services to function, indirectly supporting employment and earnings among the UK-born population.
While precise estimates vary by methodology, the scale of the figure is consistent with the MAC’s core conclusion: immigration, taken as a whole, strengthens rather than weakens the UK’s fiscal position.
MAC’s caveats are worth keeping in mind
The Migration Advisory Committee urges caution when interpreting large headline numbers. In particular:
• Estimates depend on assumptions about wages, employment rates and how long immigrants remain in the UK.
• Fiscal contribution is uneven across migrant groups and across time; early years may differ from lifetime impact.
• Economic contribution is not evenly distributed geographically, meaning national gains can coexist with local service pressures.
These caveats do not negate the positive findings, but they underline the authors’ central message: immigration’s benefits are real, measurable, and maximised by effective policy rather than by restriction alone.
Fazit
For policymakers, the report presents a contrast between evidence and rhetoric. While immigration is often framed as a cost, the MAC’s analysis suggests it is more accurately described as a fiscal asset that requires intelligent management.
For the public debate, the findings invite a shift in tone. Rather than asking how much immigration ‘costs’, the more relevant question may be how migration policy can maximise long-term contribution while ensuring that communities receive the investment they need.
The Migration Advisory Committee’s fiscal review does not claim that immigration solves all of the UK’s economic problems. What it does show, with clarity and caution, is that immigrants are contributors to the public finances, not a drain. At a time when immigration is often discussed in abstract or emotive terms, the report offers something rarer: a grounded, evidence-based assessment.
