Your pension from the UN Pension Fund may be taxed at a higher rate than it should be.

Pensions from the United Nations and other international organizations are not always taxed as ordinary pensions. Incorrect application of the tax treaty can result in losses amounting to six-figure sums over the course of a lifetime. We review your case and, if applicable, recover any overpaid taxes.

The Challenge

Not all international pensions are taxed the same way.

The tax treatment of a pension from an international organization depends on the paying organization, the applicable agreement, and your residency status. Treating it as just another Spanish pension is the most common—and the most costly—mistake.

In many cases, there are overpayments from prior tax years that can be recovered within the statutory deadlines for tax adjustments. The sooner you review your returns, the more you can recover.

  • A pension taxed at 100% without analyzing the applicable treaty.
  • Tax residency determined without taking the paying entity into account.
  • Deadlines for corrections missed because they were not reviewed in time.
  • Reporting requirements (Form 720) handled automatically.
