Deductions on $3,000 a month, line by line
Every deduction from the same gross salary in each country, in local currency, with the calculator's notes.
- Taxable base = 70% of gross salary after the flat deduction for professional expenses (article 59).
- We have not deducted social security contributions because we have not confirmed their rate from an official source. If your employer deducts a contribution, your net pay will be lower, and the tax slightly lower, because the contribution is deducted from the base up to 6%.
- Calculated for a person taxed alone. Comorian law combines the income of the head of household, their spouse and dependent children unless separate assessment is chosen.
- 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.

| VAT (standard rate) | 10% | 5% |

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 $3,000)
- Comoros 30% · Oman 0%

- Tax freedom day ($3,000)
- Comoros 8 March · Oman 1 January
- Take-home after VAT on spending

End-of-service gratuity
Oman requires employers to pay a lump sum when the contract ends. The Comoros has no general scheme. Amounts below are for $3,000 a month, with basic pay at 70% of gross and the contract ended by the employer.
| Years of service | Oman |

| 5 years | $10,500 4,037 OMR |
| 10 years | $21,000 8,074 OMR |
Resigning can reduce the amount in some countries. The end-of-service calculators apply each country's full rules.
