Check the annual threshold, the income-based ceiling and the incremental tax effect of donations to recognised organisations.

Calculate my tax saving
Maximum deduction
20% of total net income · maximum €1,000,000; €120 annual minimum
Potential saving
Depends on income, donation and the €480 allowance
Main condition
Cash donations to organisations recognised by law or approved, supported by a certificate.
Term / liquidity
None; the donation is irrevocable
A donation is deductible only if the recipient qualifies and the annual total reaches €120. Keep certificates: payment alone does not establish eligibility.

2026 calculator

Estimate donation tax relief

Eligible annual donations must reach €120 and are capped at 20% of total net income or €1,000,000.

Method and limitations

The engine applies the legal ceiling, calculates the additional reduction in taxable income, then reuses the progressive 2026 scale and employment-fund surcharge. It does not simulate an ACD decision, foreign taxation or future product taxation.

Comparison scope

Verify the organisation rather than compare a product

There is no product to rank. The useful checks are the recipient’s official eligibility and the donation certificate.

No artificial ranking

This is deliberate: the available data is not sufficiently comparable or the taxpayer does not choose the provider directly. The criteria below remain the relevant checks.

Decision

Four checks before deciding

Request a quantified written answer where a product exists. Marketing material does not replace full terms, complete fees or a suitable proposal.

01

Recipient eligibility

Check the statutory categories or official list before donating.

02

Annual threshold

Eligible donations must total at least €120 during the year.

03

Evidence

Keep a certificate stating the recipient, amount and date.

04

Ceiling and carry-forward

An amount exceeding the annual limit may be carried forward for two years under the applicable rules.

Analysis

Who is it for, why use it and what goes wrong?

Potentially suitable if…

  • A taxpayer who already wants to support an eligible cause.
  • A donor holding the necessary certificates and meeting the annual threshold.

Less suitable if…

  • Someone donating only in the hope of recovering the full amount through tax.
  • A donation to an unrecognised recipient or without usable evidence.

Common mistakes

  • Confusing an income deduction with a euro-for-euro tax credit.
  • Donating less than €120 over the entire year.
  • Failing to verify the recipient or losing the certificate.

Advantages

  • + Clear ceiling rule.
  • + Excess may be carried forward for two years.
  • + No financial product or contractual fees.

Drawbacks

  • − The donation is irrevocable.
  • − The tax saving is always smaller than the donation.
  • − The €480 allowance may neutralise the incremental effect of a small isolated donation.

Worked example

Example: €1,000 donated with €60,000 total net income

The income-based ceiling is €12,000, so the €1,000 passes that test. If no other actual special expense has used the €480 allowance, the additional reduction in taxable income is €520, not €1,000.

2026 rules

  • An eligible excess may be carried forward to the next two tax years.
  • Only recognised or approved beneficiaries qualify.
  • The standard €480 special-expense allowance may absorb some or all of the first incremental effect.
