AfterTaxLabNew York, NY vs London, United Kingdom: $100,000 against £100,000
When evaluating a salary of $100,000 in New York, the structure relies on a combination of federal, state, and local mandates. The federal layer includes specific social insurance contributions that remain constant across all American states. This environment creates a distinct take-home profile, as the payroll deductions are partitioned between various government agencies that provide specific services to residents. Understanding these layers is essential for any professional planning a career move to this urban center.

United Kingdom payroll deductions (2026 model)
No rent, cost-of-living or price data is published for London on this site — that column is deliberately empty rather than estimated.

On £100,000 the United Kingdom side gives up £31,443 (31.4% of gross) through income tax and payroll contributions. Take-home is $74,228 versus £68,557 — and the currencies are not the same, so the honest next step is the live rate below, not a verdict from these two numbers alone.
$74,228 vs £68,557 — what does that mean in one currency?
This page stores no exchange rate. Your browser fetches the European Central Bank reference rate for GBP/USD the moment the script runs, so the converted line below is true at the rate of that day and not at a rate this page froze months ago. Nothing above changes: the tax figures are published in their own currencies because that is what the two engines actually compute.
Without JavaScript the conversion cannot run — the two columns stay in GBP and USD, which is exactly why every figure on this page is published in local currency.
$75,000, $100,000 and $150,000 against £75,000, £100,000 and £150,000
Each row compares the same rung of the two ladders — the numerals are held equal on purpose so that what you see moving is the tax rule, not the currency. The percentage columns are the share of gross that reaches the worker. No exchange rate is applied to these numbers.

What $100,000 leaves in New York, NY after a year of rent
Rent is the largest line most workers cannot move, so the take-home gap is only half the story. This site publishes rents for US metros only: there is no rent series for London, United Kingdom, so this section deliberately covers one side instead of guessing the other.

A year of rent in New York, NY is $43,380 — 43.4% of the gross salary on the table — leaving $30,848 of the US take-home.
The United Kingdom column stays empty on purpose. A German or Dutch or Canadian rent figure would have to come from a proper source series; until this site holds one, the London side is a tax comparison, not a cost-of-living comparison.
Income tax and National Insurance for the UK model are rUK rates and are the same in every English, Welsh and Northern Irish city. Scotland sets different income tax bands, and Edinburgh and Glasgow sit in Scotland — the engine here uses the rUK bands, so treat those two cities as a planning figure.

Both sides run the same engines the site's calculators use: uk/calculator-uk.js on the United Kingdom side and assets/js/tax-2026.js on the US side. The US selector starts on New York, NY; the United Kingdom side is fixed to Employee only, Personal Allowance applied with the £100,000 taper, no pension contributions, not Scottish rates.
Two engines, one salary each
New York, NY: assets/js/tax-2026.js — 2026 federal brackets, the $16,100 standard deduction, FICA with the $184,500 Social Security cap, and the New York state model. London: uk/calculator-uk.js — Employee only, Personal Allowance applied with the £100,000 taper, no pension contributions, not Scottish rates. Both engines are the ones loaded by the site's own calculators, and both are checked at build time against tax-rules/2026.json.
The New York tax model involves a progressive state income tax alongside federal obligations. A worker sees their earnings reduced by FICA, which encompasses Social Security and Medicare components, in addition to standard income tax withholdings. The state line represents the specific contribution to New York’s regional budget, which is calculated independently of federal requirements. This layered approach ensures that the total deduction equals 25.8% of the initial gross amount, leaving the worker with $74,228 to manage their annual expenses and savings effectively.
The United Kingdom payroll system operates through a primary income tax structure with graduated rates. The first portion of earnings is subject to a basic rate, while subsequent brackets increase the percentage taken by the state. National Insurance serves as a parallel contribution, funding specific social protections. Unlike the American system, these deductions are often aggregated to support a unified public healthcare service and pension obligations. With a total deduction reaching 31.4% of the gross salary, the resulting take-home pay is £68,557, reflecting the broader scope of taxpayer-funded public services in this region.
Using identical numerals in two distinct currencies provides a neutral framework to observe how tax rules interact with gross salary. This methodology avoids the bias of volatile exchange rates, focusing purely on the legislative architecture of each jurisdiction. However, this comparison stops being useful if the user assumes it measures purchasing power or standard of living. It is strictly a tool to visualize how governments claim their share of income. Because tax codes are subject to legislative updates, please note that this is not tax advice.
New York, NY or London? What it means in practice
In London, a gross salary of £100,000 is processed through a different fiscal framework governed by His Majesty's Revenue and Customs. This system utilizes a progressive income tax band structure alongside National Insurance contributions. The personal allowance significantly shapes how these deductions apply, particularly for those earning near the upper threshold of the current bracket. Analyzing this deduction stack reveals how the United Kingdom prioritizes public funding differently than the American model, providing a clear view of the net income outcome.
In New York, the practical reality of this salary includes high fixed costs, such as the average rent of $3,615 per month. After accounting for these housing expenses, the remaining annual take-home balance is $30,848. This amount must cover all other personal costs, including utilities, transport, and food. While the gross figure is identical to the London example, the actual portion of the income that remains flexible depends heavily on the specific housing market and the tax burden associated with the state of residency.
People often misunderstand this comparison by attempting to force a conversion between currencies, which masks the underlying tax efficiency. Another common error is assuming that social insurance contributions provide identical benefits on both sides. In reality, the deductions in the United Kingdom fund a different set of universal social programs compared to the American FICA system. Furthermore, while rent data for New York is readily available, such figures are not provided for London here, preventing a like-for-like comparison of residual income after housing.
New York, NY vs London: common questions
How does the New York state line affect my total deductions?
The state income tax in New York is a specific component that adds to your federal tax burden. It is calculated as 4.95% of your gross pay, which totals $4,952. This remains constant regardless of your housing expenses.
What do the United Kingdom deductions actually fund?
In the United Kingdom, your tax and National Insurance contributions support a wide array of public services. This includes the National Health Service and the national pension system, which are funded through these specific payroll deductions.
Are social insurance costs higher in one location?
The American FICA deduction represents a $7,650 contribution toward federal programs. In contrast, the United Kingdom utilizes a separate National Insurance system that takes £4,011 from your annual gross pay.
Why shouldn't I convert the two salaries into one currency?
Converting currencies creates a false sense of purchasing power parity. This page uses identical numerals to compare only the tax logic, as the true value of money is local to the market where you spend it.
Where can I find rent data for London to compare?
This page does not provide rent data for London. Rent information is only available for United States metros via Zillow, so a housing cost comparison is not possible within this tool.
Who does this tax model suit best?
The New York model suits those who prefer a lower overall tax bite relative to the United Kingdom, while the London model suits those who prefer higher payroll deductions in exchange for extensive, state-funded public social services.
