Dominica’s Flat Income Tax Plan: Who Could Benefit from the 10% Rate?

by Adam Fayed on

Dominica plans to introduce a 10% flat personal income tax from January 1, 2027, replacing its current progressive rates of 15%, 25%, and 35% while retaining the EC$30,000 personal allowance.

The reform would also change the treatment of foreign income, with the government proposing that residents and non-residents be taxed only on income earned in Dominica.

Key Takeaways

  • Dominica's tax advantages will be based on the final rules governing income source and tax residence.
  • The proposed territorial system could exempt qualifying foreign-source income from Dominican tax.
  • Dominica's current income-tax rates remain 15%, 25% and 35% until the proposed 10% system takes effect.
  • Italy and Greece offer HNWIs fixed annual taxes on qualifying foreign income.

DOMINICA FLAT TAX 10% GUIDE

What is Dominica's new 10% flat tax?

Dominica's new 10% flat tax is a proposed single personal income tax rate that will replace the country's existing progressive tax bands from January 1, 2027.

Currently, Dominica applies a 15% rate to chargeable income between EC$30,001 and EC$50,000, 25% to the next EC$30,000, and 35% to income above EC$80,000.

Individuals are entitled to a EC$30,000 resident allowance, meaning income up to that threshold is not subject to personal income tax.

This means the reform is not simply a reduction in the top marginal rate.

It also changes the structure of the system from progressive taxation to proportional taxation.

What does Dominica's 10% flat tax mean for HNWIs?

For HNWIs, Dominica's proposed 10% flat tax could lower the tax on Dominican-source personal income while the planned shift to territorial taxation could exclude qualifying foreign-source income from Dominican income tax.

A high-income individual earning substantial income from activities in Dominica could therefore see a significant reduction in personal income tax liability compared with the current 35% top marginal rate.

However, the more consequential part of the reform for internationally wealthy individuals is the government's proposed treatment of foreign income.

From January 1, 2027, Dominica says residents and non-residents will pay income tax only on income earned in Dominica.

Someone who becomes tax resident in Dominica could potentially have:

outside the scope of Dominican income tax if those amounts are genuinely foreign-source under the final rules.

How to reduce tax for high earners in Dominica?

High earners can reduce their tax exposure in Dominica by using the available personal allowances and deductions, managing the timing and source of income, and reviewing their tax residence before relocating.

For individuals earning substantial employment or business income, the proposed flat 10% rate would itself reduce the marginal tax burden compared with the current 35% top rate.

Under the existing system, residents can also claim the resident allowance and qualifying deductions when calculating chargeable income.

For HNWIs, additional planning can involve:

  • Timing income: Where commercially and legally practical, the timing of bonuses, distributions, asset sales, or other taxable receipts can affect the year in which income is assessed.
  • Using allowable deductions: Claiming available deductions and allowances can reduce chargeable income before tax is calculated.
  • Separating personal and business income: Individuals operating businesses should assess whether income is being earned personally or through a company, taking into account the different tax treatment that may apply.
  • Reviewing foreign income: High earners with overseas investments, property, pensions, or businesses should establish how each income stream is treated under Dominica's rules rather than assuming all foreign income receives the same treatment.
  • Planning tax residence: The timing of a move to Dominica can affect the individual's tax position, particularly where the person is also potentially tax resident in another country.

Dominica's current rules generally treat residents as taxable on global income, while the Inland Revenue Division states that income from a Dominica source is taxable even for non-residents.

Which countries have flat taxes?

Countries with flat personal income tax rates include Bulgaria, Romania, North Macedonia, Hungary, Georgia, and Estonia, while Dominica is proposing a 10% flat rate from 2027.

Dominica's proposed 10% rate places it among the countries with the lowest flat personal income tax rates.

However, the headline rate alone does not determine the overall tax burden.

Countries differ in how they treat foreign income, capital gains, dividends, social contributions, deductions, allowances, property, and inheritance.

A country with the same 10% headline rate as Dominica can therefore produce a very different tax outcome for an individual with substantial foreign income or investment assets.

How does Dominica compare with Italy for HNWIs?

Dominica’s plan could offer HNWIs a lower local tax bill on qualifying foreign income than Italy’s €300,000 annual lump sum regime.

That potential advantage rests on the foreign income being excluded under Dominica’s final rules, while Italy already provides an established regime for eligible new residents.

Italy has a progressive ordinary income tax system, but qualifying new residents can elect its special lump sum regime instead of the ordinary taxation of foreign-source income.

For individuals transferring their legal residence to Italy from January 1, 2026, the annual substitute tax is €300,000, regardless of the amount of qualifying foreign income.

Eligible family members can be included for an additional €50,000 each.

Italy’s fixed €300,000 charge can offer savings compared with ordinary Italian taxation for HNWIs generating substantial qualifying foreign income.

Its effective rate falls as that income increases, although it would still represent an additional local tax cost compared with income excluded under Dominica’s proposed territorial rules.

How does Dominica compare with Greece for HNWIs?

For HNWIs whose income is predominantly foreign-source, Dominica’s plan could be more attractive on income tax than Greece’s €100,000 annual regime.

Greece offers an established arrangement lasting up to 15 years, while Dominica’s potential savings remain subject to the final legislation and income source rules.

Under Greece's Article 5A regime, qualifying individuals who transfer their tax residence to Greece can elect to pay a fixed annual tax of €100,000 on their foreign-source income, instead of being taxed under the ordinary Greek rules on that income.

For an HNWI earning €1 million in qualifying foreign income, Greece's €100,000 charge represents an effective rate of 10%.

As foreign income rises, the effective Greek tax rate falls, potentially offering savings compared with ordinary Greek taxation. This would not create a tax advantage over Dominica if the same income qualified for exclusion under its proposed territorial rules.

Conclusion

Dominica's proposed reform could put it in a distinctive position among low-tax jurisdictions by combining a low personal income tax rate with a territorial model rather than relying on a high-net-worth lump sum regime.

For HNWIs, this creates an interesting trade-off. A percentage-based system can be more attractive than a fixed annual charge when taxable income is moderate, while the opposite can be true at very high income levels.

The final legislation will determine where Dominica sits on that spectrum.

The key issue to watch before January 2027 is therefore how the legislation defines the source of income and the scope of the 10% tax.

Those details will ultimately determine whether the reform delivers the level of tax efficiency suggested by the headline rate.

FAQs

What is another name for a flat tax?

A proportional tax is another name for a flat tax because the same tax rate applies to taxable income regardless of how much an individual earns.

Which tax system imposes higher rates on higher income?

A progressive tax system imposes higher marginal tax rates as taxable income increases.

Dominica currently uses progressive rates of 15%, 25%, and 35%, while its proposed 2027 system would replace these marginal rates with a single 10% rate.

Who is the most heavily taxed country in the world?

By tax wedge, Belgium had the highest rate among OECD countries in 2025 at 52.5% for a single worker without children earning the average wage.

By personal income tax, Denmark has one of the highest top rates, reaching approximately 57% in 2026, or 60.5% including the labor market tax, as per PwC.

What country has the lowest income tax?

The lowest personal income tax rate is 0%, available in jurisdictions such as the Bahamas, Bahrain, Bermuda, the Cayman Islands, Kuwait, Qatar, and Saudi Arabia, although other taxes and charges still apply.

If implemented, Dominica’s proposed 10% flat rate from 2027 would place it among jurisdictions with low standard personal income tax rates.
