Answer simple questions and copy the figures from your employer’s confirmation. Next to each field, there is an explanation of what goes in it. You see the tax, the child bonus, the mortgage interest bonus and the refund straight away. You get the completed DPFO form as a PDF and the XML file for filing for €14.95. We will add the 2026 form as soon as the Financial Administration (the Slovak tax authority) publishes it.
The AI assistant explains every field while you fill in the form – it is unlocked once you pay €14.95.
… in 2026 you had only income from employment in Slovakia – even from several employers or from work agreements – and you want to claim children, a mortgage or your spouse, or assign 2% or 3%.
… you are self-employed, have rental income or income from abroad, or are filing a supplementary tax return. In that case, the form will stop you – we will prepare such a tax return for you.
Filling in takes about 15 minutes. Not sure what a question means? Click the next to it.
Fills in the form with the data of a fictitious employee with two children and a mortgage. With the sample, you can download the PDF and XML for free and see what you will get.
A few short questions will decide whether we can prepare your tax return here or whether it needs to be handled differently. Just answer Yes or No.
Did you have income from employment in 2026?*Employment contract, work agreements, company director’s remuneration, civil service.
Type A cannot be filed without income from employment. Write to us and we will advise you whether you need to file a tax return at all.
Ask our accountantDid you have any other income that needs to be declared?*Self-employment, rental, royalties, sale of shares or cryptocurrencies, sale of property within 5 years.
This income is reported in a type B tax return, where it is easy to make mistakes. We will prepare it for you, including expenses and contributions.
I want you to prepare my tax returnWith a foreign salary, what matters is the double taxation treaty with the country concerned, the exchange rate and the method of exemption or tax credit. The online form cannot handle this reliably.
Handle it for meAre you filing the 2026 tax return for the first time?*If you have already filed it and want to correct it, answer No.
It has to be compared with the original filing and the differences filled in correctly. Send us what you filed.
Contact meWere you a tax resident only of Slovakia in 2026?*You lived in Slovakia and did not also have a home in another country.
If you have a home in two countries or stay abroad, the double taxation treaty is decisive. The online form cannot handle this reliably.
Handle it for meA tax return for a deceased person or filed by a representative contains details of the representative, and different deadlines apply for a deceased person. The online form does not handle this.
Contact meAs a rule, you do not need to file a tax return. If you want to claim something that was not included in the reconciliation, you file an ordinary tax return, which must build on what your employer has already settled. Have your Confirmation of the annual tax reconciliation (Doklad o vykonanom ročnom zúčtovaní) ready.
Assess it for meDo you want to claim the interest bonus on a loan that you refinanced with a new contract?*If you are not claiming the interest bonus, answer No.
A refinanced loan does not give rise to a bonus. However, you may still be entitled to it for interest on the original loan paid before refinancing. So do not add up the amounts from the two banks – send us both confirmations.
Assess it for meIs there a co-borrower on your mortgage who was not 18 to 35 when applying for the loan, or are you a co-borrower on another loan with a bonus?*If you are not claiming the interest bonus, answer No.
In that case, you are not entitled to the interest bonus (§ 33a(4) and (6)). You can still file the tax return without it – answer No to the mortgage question in step 6.
If you previously deducted the contributions from your tax base, after an early withdrawal the tax base must be increased by them – in the tax return for the third year after the year of the withdrawal at the latest. We will assess by how much and in which year based on your statements.
Assess it for meCopy them from your ID card. The address is that of your permanent residence on the day you file the tax return.
You will find all the figures on the Confirmation of taxable income (Potvrdenie o zdaniteľných príjmoch) that your employer gives you. You just copy them; you do not calculate anything. If you had more than one employer, add each one separately.
We will fill in the amounts from the confirmation for you, with each confirmation as a separate employer. The file stays on your computer – it is not sent to the server. It works with a confirmation on the Financial Administration form in PDF format, not with a scan.
Amounts on which no tax is paid. The one you are entitled to for yourself has already been deducted: €5,966.73. Here, just answer whether any of the following applies to you.
Were you receiving an old-age, early old-age or service pension as at 1 January 2026?*Also if it was granted later, but retroactively to 1 January 2026 or earlier.
Do you want to claim the non-taxable part for your spouse?*For example, if they were on maternity or parental leave or registered with the labour office.
Do all your 3rd pillar contracts meet this condition?*Concluded after 2013, or the benefit plan was cancelled in an older contract. PEPP always meets the condition.
With such a contract, you cannot deduct the contributions from your tax base. Once the benefit plan has been cancelled by an amendment to the contract, you will be able to deduct contributions paid after that change. If you cancelled it during 2026, ask us.
€100 a month per child up to the age of 15, €50 from 15 to 18. We work out the age periods and the amount from the birth number. Check the months of entitlement against your own situation.
The child bonus is limited by the amount of your tax base. If the other parent or your spouse also supports the child in your household, the law allows their tax base to be added when calculating the bonus – the bonus may then be higher. The online form does not do this – we will assess it for you.
The form can handle up to 6 children. If you are claiming the bonus for more children, we will prepare the tax return for you.
For young people up to 35 with a loan for their own home. It refunds half of the interest you paid, up to €400 or €1,200 a year depending on when you signed the contract.
In step 1, you stated that a co-borrower was not 18 to 35 when applying for the loan, or that you are a co-borrower on another loan with a bonus. In that case, there is no entitlement to the interest bonus. Answer No here – you will file the tax return without it.
You can send part of the tax you will pay anyway to an organisation, plus 2% to each of your retired parents. It costs you nothing extra. It is calculated from the tax after deducting bonuses, not from the tax advances or the refund. The tax office will send the share only if, 15 days after the filing deadline, you do not owe more than €5 in tax – if you have tax to pay, pay it on time.
If you are due a refund, state where the tax office should send it. Then check the result on the right and download your finished tax return.
Pay any tax due by 31 March 2027. The tax office will send you any refund within 40 days of the end of the filing deadline.
Deadline for filing and payment: 31 March 2027.
The form only asks about what applies to you. Where you answer No, the fields disappear.
Everything you need is on the Confirmation of taxable income (Potvrdenie o zdaniteľných príjmoch) from your employer. There is an explanation next to every field.
The tax, the child bonus, the mortgage bonus and the refund are recalculated as you type – under the law in force in 2026.
For €14.95 you get the completed official form as a PDF for printing and an XML file for filing online. Filing takes just a few minutes. We will add the 2026 form as soon as it is published.
A type A tax return is filed by an employee whose taxable income for 2026 exceeded €2,983.37 and whose employer did not carry out the annual tax reconciliation. Typically, these are people who changed jobs during the year, had two employers at the same time or did not request the reconciliation.
It is also worth filing a tax return voluntarily – for example, if you want a tax refund, or to claim the child tax bonus (€100 a month up to age 15, €50 up to 18), the bonus on interest paid on a mortgage (up to €1,200 a year), the non-taxable part for your spouse or 3rd pillar contributions.
From 2026, four tax rates apply to individuals: 19%, 25% above €43,983.32, 30% above €60,349.21 and 35% above €75,010.32 of the tax base. The non-taxable part of the tax base for the taxpayer is €5,966.73 and is reduced at higher incomes. The form calculates all of this for you.
The deadline for filing the return and paying the tax is 31 March 2027. If you are self-employed or have rental income, you need type B; we assess salary from abroad individually – we can handle both for you.
You see the calculation and the checks straight away. You receive the completed form as a PDF and the XML file for filing after payment – the price is €14.95 and includes help from the AI assistant while filling it in. The download key is valid for your name and birth number, so if you correct something, you can download the tax return again at no extra charge. The Financial Administration has not yet published the form for 2026 – for now, the PDF and XML follow the 2025 template and are not yet suitable for filing for 2026. As soon as the new form is published, we will add it here and you can download your tax return again with the same key, at no extra charge.
As a rule, no. You can file one if you want to claim something that was not included in the annual tax reconciliation, such as the mortgage interest bonus. It is an ordinary tax return, but it must build on the result of the annual tax reconciliation, so the online form does not handle it – we will assess it individually.
Not the data from your tax return. A tax return in progress is stored only in your browser, so you can come back to it. On someone else’s computer, delete it at the end using the Clear data button. Tax return data is sent to us only briefly while we generate the PDF and XML, and is discarded immediately. We keep only what you enter when ordering (billing details, email address and variable symbol – for the payment, the key and the invoice) and your conversations with the AI assistant: we keep their transcripts for three years, and our accountant also reads them so that she can improve the service. So do not write more in them than necessary.
In two ways. On paper: print the PDF – the official form, already filled in – sign it, add the attachments and send it by post or take it to the tax office. Electronically: load the XML file into the form on the Financial Administration portal and file it using your ID card with a chip.
If you are self-employed, have rental income or other income outside employment, a type B return is filed. A salary from abroad on its own may still fall under type A, but the online form does not handle calculations involving foreign income. In both cases, the form will stop you, and we will be happy to prepare the tax return for you.
The tax office will refund the overpayment within 40 days of the end of the filing deadline, provided you have requested the refund and stated your account number.

MATU.SK s. r. o., Sabinovská 362/5, 821 03 Bratislava, IČO 50 756 893, DIČ 2120466810, registered in the Commercial Register of the Bratislava III Municipal Court, Section Sro, Insert No. 132609/B. Not a VAT payer. Contact: uctovnictvo@matu.sk, +421 904 343 950.
The key is valid for the first name, surname and birth number you paid for, and for one tax year. You can use it to download the tax return repeatedly, even after correcting other data. A tax return for another person is a new order. Do not give the key to anyone.
You fill in the tax return yourself, so we are not responsible for its accuracy. You are responsible for ensuring that the data is true, complete and correctly copied from your documents, and that type A applies to you, as well as for filing the tax return and paying the tax on time. The calculation, the explanations next to the fields and the AI assistant’s answers are an aid, not professional advice – the AI assistant can make mistakes. We are not liable for any additional tax, interest, penalties or other consequences arising from your data or from decisions you made while filling in the form. If you are unsure, order a review by our accountant.
We are responsible for ensuring that the PDF and XML correspond to the data you entered and that the calculation based on them complies with the law in force for the relevant year. If there is an error in our calculation or in the file (for example, the Financial Administration portal rejects the XML because of a file error), we will correct it free of charge; if that is not possible, we will refund the price.
Until the Financial Administration publishes the 2026 form, the PDF and XML follow the 2025 template and cannot be used to file the 2026 tax return. You purchase them in the knowledge that this is a test version. Once the form is published, we will add it and you can download your tax return again with the same key, at no extra charge.
As a consumer, you may withdraw from the contract within 14 days without giving a reason. However, the PDF and XML are digital content that we make available to you immediately after payment. In your order, you therefore expressly request access before this period expires and acknowledge that you lose the right of withdrawal once the key is sent. Until we send the key, you may withdraw by email and we will refund the amount paid within 14 days.
If the PDF or XML does not meet the requirements of the form, or contains an error in our calculation, write to uctovnictvo@matu.sk and describe what is wrong. We will handle the complaint without undue delay and within 30 days at the latest – by correcting the error or, if that is not possible, by refunding the price. An error in the data you entered is not grounds for a complaint.
The contract is governed by Slovak law. Please contact us first with any concerns. If we do not resolve your complaint to your satisfaction, you may, as a consumer, contact the Slovak Trade Inspection (Slovenská obchodná inšpekcia, soi.sk), which also handles alternative dispute resolution. We may amend these terms; an order that has already been paid for is governed by the terms in force at the time of the order.

You fill in the tax return yourself in this form, and the AI assistant explains every field. You get a finished PDF and an XML file for filing. Until the Financial Administration publishes the 2026 form, this is a test version.
You fill in the tax return yourself and our accountant reviews it, pointing out mistakes and any tax reliefs you have missed.

This is a test version. The Financial Administration has not yet published the form for 2026, so the PDF and XML you receive now follow the 2025 template and cannot be used to file the 2026 tax return. We will launch the final version once the Financial Administration publishes the forms – you can then download your tax return again with the same key, at no extra charge.
We will issue the invoice to these details. You will immediately receive an advance invoice for payment by email and, after payment, the key to download your tax return together with the invoice. If you are a company (with an IČO or DIČ), we will also send the invoice as an e-invoice.
Test version: for now, the PDF and XML follow the 2025 template and cannot be used to file for 2026. You will download the final version with the same key once the Financial Administration publishes the forms.
Scan the QR code in your banking app or enter the payment manually – the variable symbol is important. In a moment, you will receive an advance invoice with the same payment details at . We check for payments every 6 minutes, and as soon as the money reaches our account, we will send you the key together with the invoice. An instant payment arrives immediately; a standard transfer from another bank arrives by the next working day at the latest.
Enter the key you received by email after paying. It is valid for the first name, surname and birth number you paid for – if you change them, the key will not match.
We process the conversation and the data you enter in line with our privacy policy. We send the chat transcript to the accountant and, once you confirm your address, to you as well.
