Effect of Tax Deduction Schemes and Incentives for Donations to Voluntary Organisations

This project investigates the impact of tax deduction schemes on monetary donations to voluntary organisations, with a focus on social inequality and distribution effects. The goal is to document how tax deductions influence donation patterns and the organisations' revenues.

Project period January 2025–December 2027
Project nr. 10846
Project leader Daniel Stoltenberg

Background

In 2003, Norway implemented a scheme where private individuals could receive tax relief for monetary donations to approved voluntary and non-profit organisations. The aim was to create incentives for private financial support to the voluntary sector by reducing the cost of donating through tax deductions. Existing research suggests that tax deductions have a marginal effect and are more significant for the wealthy than for the average taxpayer. Preliminary findings indicate that the effect of tax deduction schemes is socially differentiated, with high-income individuals more likely to donate and give larger amounts. It is uncertain whether increased limits for tax deductions actually lead to higher donation revenues for organisations. There are many different tax deduction schemes for monetary donations in various countries, and these vary in the size of deductions that can be claimed and the amount of tax reduction provided. The project will also explore the extent to which the institutional context influences monetary donations. Some organisations receive a large portion of their income from monetary donations, but little is known about how the incentive effects of tax deductions vary for different types of organisations.

Project Approach

The project will link register data on monetary donations, tax deductions, deduction amounts, and social background variables. The analyses will focus on changes in the threshold for tax deductions to measure the effects of the scheme on donors and donation amounts, as well as analyse distribution effects in the population and between organisational categories. The research questions include:

  • Who in the population makes monetary donations, how much they donate, and for which purposes, as well as changes over time.
  • The extent to which Norwegian households' and individuals' monetary donations vary by social class and socio-economic characteristics.
  • The effect of tax deductions on monetary donations to voluntary organisations, including whether individuals donate and how much they donate when the threshold changes.

The project will culminate in a report to be delivered in 2027, as well as an international journal article and dissemination of findings in Norwegian in a chapter in a report or book.
