Deductions on $5,000 a month, line by line
Every deduction from the same gross salary in each country, in local currency, with the calculator's notes.
- Calculated annually on a standard 1257L tax code. In practice National Insurance is worked out on each monthly pay separately; the annual result is the same if the salary is steady.
- Student loan repayments and workplace pension auto-enrolment contributions (usually 5% from the employee within a set band) are not included, because you can opt out of the pension.
- The Personal Allowance is tapered above £100,000, which is why an effective marginal rate of 60% (or 67.5% in Scotland) shows in this range.
- The employer contribution does not include the Employment Allowance, which many small businesses claim.
- There is no income tax on salaries in Oman in 2026. Personal income tax (5% on income above 42,000 rials a year) starts on 1 January 2028.
- Nothing is deducted from a non-Omani's salary in 2026. The work injury branch for non-Omanis is deferred to July 2028, and the savings scheme (9% of basic pay, paid by the employer) starts on a date set by the Social Protection Fund board before July 2027; it is not calculated here.
Income tax and social insurance side by side
| Item | UK | Oman |
|---|---|---|
| Income tax on salaries | 0% to 45% (up to 48% in Scotland) | None |
| Top income tax rate | 45% | 0% |
| Employee social insurance | National Insurance 8% between £12,570 and £50,270 a year, and 2% above that | Expats 0%, Omanis 8% (7.5% old age, disability and death + 0.5% job security) |
| Employer contributions on $5,000 | 13.3% | 0% |
| VAT (standard rate) | 20% | 5% |
| Corporate tax | 25% | 15% |
| End-of-service gratuity | No general scheme | Set by the labour law |
| Currency | British pound (GBP) | Omani rial (OMR) |
| Tax authority | HM Revenue & Customs | Oman Tax Authority |
| Double tax treaty between them | In force (1998) | |
Where the numbers shift
- Turning point
- The better choice does not change between $500 and $30,000 a month
- Taken from your next raise (on $5,000)
- UK 20% · Oman 0%
- Marginal rate on $10,000
- UK 40% · Oman 0%
- Tax freedom day ($5,000)
- UK 16 March · Oman 1 January
- Take-home after VAT on spending
- UK $3,323 · Oman $4,762
- Employer cost on top of salary
- UK 13.3% · Oman 0%
Take-home after VAT = take-home pay ÷ (1 + the standard VAT rate): what the salary is worth if all of it is spent on goods at the standard rate. Tax freedom day: the day of the year on which you stop working to pay tax and contributions.
End-of-service gratuity
Oman requires employers to pay a lump sum when the contract ends. The UK has no general scheme. Amounts below are for $5,000 a month, with basic pay at 70% of gross and the contract ended by the employer.
| Years of service | Oman |
|---|---|
| 2 years | $7,000 2,691 OMR |
| 5 years | $17,500 6,729 OMR |
| 10 years | $35,000 13,457 OMR |
Resigning can reduce the amount in some countries. The end-of-service calculators apply each country's full rules.
Beyond salary: investments, family and residence
| Item | UK | Oman |
|---|---|---|
| Gains on shares (top rate) | 24% | 0% |
| Gains on property (top rate) | 24% | 0% |
| Dividends | 39.4% | 0% |
| Crypto gains | Taxed | Not taxed |
| Inheritance tax | Yes, up to 40% | No |
