The Tax Foundation’s International Tax Competitive Index (ITCI) ranks OECD members on how attractive their tax systems are for businesses. The 2021 edition, the eighth annual release, highlights shifts in competitiveness, identifies the current leaders, and offers a snapshot of the broader tax‑policy landscape that entrepreneurs and investors must navigate.
How the index works
The ITCI evaluates three pillars:
- Tax rates – corporate income tax, withholding taxes, and other headline rates.
- Tax base – breadth of taxable activities and deductions.
- Simplicity – filing frequency, number of forms, and overall administrative burden.
Only OECD countries appear, meaning many well‑known offshore havens (e.g., Vanuatu, St. Kitts & Nevis) are excluded.
Top performers in 2021
| Rank | Country | Notable features |
|---|---|---|
| 1 | Estonia | Aggressive incentives for reinvested profits; e‑residence program (though its value is debated). |
| 2 | Latvia | Mirrors Estonia’s tax model, offering similar reinvestment benefits. |
| 3 | New Zealand | Low corporate tax and a transparent system, but a small domestic market limits talent pools. |
| 4 | Switzerland | Stable rates, strong financial infrastructure, and high‑skill workforce. |
| 5 | Luxembourg | Favorable holding‑company regime and extensive treaty network. |
| 6 | Lithuania | Adopted a competitive corporate tax structure aligned with Baltic peers. |
| 7 | Czech Republic | Ongoing reforms improving the business environment. |
| 8 | Sweden | Recent corporate‑tax cut from 59 % to 55 % (still high by OECD standards). |
| 9 | Australia | Competitive rates for certain industries, but complex compliance. |
| 10 | Norway | High VAT but relatively moderate corporate tax. |
Countries that improved most (2014 → 2021)
- Israel – 28 → 14: Gains driven by a tech‑friendly environment despite relatively high rates.
- United States – 31 → 21: Benefited from the 2017 Tax Cuts and Jobs Act, which lowered the headline corporate rate to 21 %.
- Hungary – 21 → 13: Corporate tax reduced to 9 % (the OECD low), though it carries the highest VAT in the bloc.
- Chile – 33 → 27: Incremental tax‑incentive adjustments, though some reforms have been rolled back.
- Canada – 25 → 20: Adopted short‑lived asset expensing similar to the U.S., modestly raising its rank.
Countries that slipped
- Turkey – 12 → 17: Corporate‑tax hikes eroded competitiveness.
- Poland – 30 → 36: Policy shifts moved it down the list.
- Belgium – 15 → 23: Increased rates and regulatory burdens.
- Colombia – 17 → 31: Raised VAT and corporate income tax; however, residency rules mean a non‑resident can avoid Colombian taxes while operating elsewhere.
What the numbers mean for entrepreneurs
- Headline rates are only part of the picture – Hungary’s 9 % corporate tax looks attractive, but the country imposes a 27 % VAT and numerous other levies (real‑estate transfer, bank‑asset taxes).
- Simplicity matters – Jurisdictions that have moved away from flat‑tax simplicity (e.g., Barbados, Labuan) may increase compliance costs even if rates stay low.
- Residency vs. incorporation – Tax obligations depend on where a business is managed and where its owners reside. Living part‑time in a low‑ranked country (e.g., Colombia) does not automatically subject you to its corporate tax regime.
- Talent and market access – Small economies like New Zealand offer low taxes but limited labor pools; larger hubs such as the UAE or Singapore (outside the OECD) provide broader talent access and zero‑tax regimes.
- Future policy risk – The OECD’s global minimum tax, slated for implementation in the coming years, could neutralize advantages of low‑rate jurisdictions for firms with nine‑figure revenues.
Practical considerations when choosing a tax jurisdiction
- Assess total tax burden – Combine corporate tax, VAT, payroll taxes, and any sector‑specific levies.
- Evaluate administrative load – Number of filings, need for local accounting, and language barriers affect operating costs.
- Check treaty networks – Double‑taxation agreements can reduce withholding taxes on cross‑border payments.
- Consider regulatory stability – Frequent legislative changes (as seen in Chile and Turkey) increase uncertainty.
- Plan for substance requirements – Many OECD countries enforce “management and control” rules; a mere shell company may not satisfy tax residency tests.
Bottom line
The ITCI provides a useful snapshot of tax competitiveness among OECD members, highlighting leaders like Estonia and Hungary and flagging jurisdictions where rising rates or complexity erode appeal. However, entrepreneurs should look beyond headline rankings, weighing total tax exposure, ease of compliance, talent availability, and the likelihood of future policy shifts—especially the looming global minimum tax—before deciding where to incorporate or operate.
