Support us

For the future of nature — together with you.

Your support is what keeps the environmental work, the teaching and the projects going. You can help with a direct gift, or by assigning 2% of your Slovak income tax — which costs you nothing extra.

Assign 2% of your tax

This is a share of tax you pay to the state anyway — you simply decide where it goes. It costs you nothing extra. Choose the case that applies to you.

I am an employee

Your employer files your tax return. You send two forms to the tax office yourself.

  1. Ask your employer for the annual settlement

    By 15 February 2027 at the latest, ask your employer to carry out the annual tax settlement for 2026 and to issue you the form „Potvrdenie o zaplatení dane“ (confirmation of tax paid).

  2. Work out the amount

    The confirmation tells you how much tax you paid. You can assign 2% of it — or 3% if you did at least 40 hours of volunteering during 2026 and hold a certificate for it.

  3. Fill in the declaration

    Download the form „Vyhlásenie o poukázaní podielu zaplatenej dane“, fill in your details, the amount and our details below. Remember to sign it.

  4. Deliver both forms to the tax office

    By 30 April 2027, deliver the declaration together with the confirmation of tax paid to your tax office — by post or in person.

A note on the 3% rate

If you are assigning 3% on the basis of volunteering, attach the certificate of at least 40 hours worked. Without it the tax office will not accept the 3%.

We do not host the forms ourselves — the links go straight to the Financial Administration, so you always get the version valid for that year.

I file my own tax return

No separate form is needed — everything is inside the tax return itself.

  1. Work out 2% of your tax

    The minimum is €3. If you did at least 40 hours of volunteering during 2026 and hold a certificate for it, you may assign 3%.

  2. Fill in the section of the tax return

    In return type A it is section VIII, in type B section XII. Enter our details from the list below.

  3. File the return and pay the tax

    By 31 March 2027, or by 30 June 2027 if you have an extension. The tax itself must be paid within the same deadline.

A note on the 3% rate

For the 3% rate, attach a certificate of at least 40 hours of volunteering to your tax return. Without it the claim will not be accepted.

We do not host the forms ourselves — the links go straight to the Financial Administration, so you always get the version valid for that year.

We are a company

A company assigns 1% or 2% and may split the amount between several recipients.

  1. Check whether you assign 1% or 2%

    If in the previous year the company donated at least 0.5% of its tax to a public-benefit purpose — to any organisation — it may assign 2%. Otherwise it assigns 1%.

  2. Fill in part VI of the tax return

    Enter our details from the list below. The amount may be split between several recipients — at least €8 per recipient.

  3. Attach a sheet if there are several recipients

    A separate sheet listing the recipients, how many there are and the amount for each.

  4. File the return and pay the tax

    By 31 March 2027, or by 30 June 2027 if you have an extension.

A note on 1% and 2%

The only difference is whether the company donated at least 0.5% of its tax to a public-benefit purpose in the previous year. If it did, ticking the box in the return is enough and it assigns 2%.

We do not host the forms ourselves — the links go straight to the Financial Administration, so you always get the version valid for that year.

Our details for the form

Name Pro Enviro n.o.
Legal form Non-profit organisation providing services of general benefit
IČO (company ID) 35582987

Important

Write the IČO without spaces and aligned to the right, exactly as the form's instructions require. A wrongly written IČO is the most common reason a tax share never arrives.

If you would like us to know whom to thank, tick the consent box on the form. The tax office then sends us your name and address only — never the amount.

    Employees ask their employer for the annual tax settlement.

Give us your time

Field days, workshops and community projects always need more hands. Tell us what you can do and how much time you have — we will write back with what is coming up.

At least 40 hours of volunteering in a year also means you can assign 3% of your tax instead of 2%.

Common questions

Does assigning 2% cost me anything extra?

No. It is part of the tax you pay to the state anyway. If you assign it to nobody, it simply stays in the state budget.

Can I split the share between several organisations?

An individual cannot — the whole amount goes to one organisation. A company can, with at least €8 per recipient.

When does the money arrive?

The tax office transfers the share within three months of the declaration deadline, provided the details are in order.

Will I get a confirmation of my gift?

Yes, on request. Send us an e-mail with the date and amount of the transfer and we will issue one.

How do I find out what the support was used for?

Write to us and we will tell you which projects the money went into. Annual accounts of Slovak non-profits are also public in the national register of financial statements.

Still have a question?

Write or call — we are glad to help with the forms or with choosing how to give.
