What sources does Taxxa search?

Taxxa searches a continuously updated collection of more than one million pages from tax authorities, government publications, legislation and case law across the European jurisdictions it covers. Every response cites the underlying material, so a professional can inspect the rule, its jurisdiction and whether it is current before relying on the result.

Can Taxxa work with a team’s own documents?

Yes. Research can combine the public knowledge base with a team’s own PDF, DOCX, CSV and TXT files in one workspace. That makes it possible to compare a client document with the relevant guidance, trace a conclusion to its source and prepare a draft without losing the evidence that supports it.

Who is Taxxa built for?

Accountants, auditors, tax advisors, payroll specialists, bookkeepers and advisory teams working across European jurisdictions. Shared workspaces keep research available to colleagues, and citations make review easier.

Where is customer data stored, and is it used to train models?

Customer data stays in the European Union and is never used to train language models.

Does Taxxa replace professional judgement?

No. Taxxa is a research and drafting workspace. It helps professionals reach an informed starting point faster; the professional still reviews the evidence and makes the final decision. It does not file returns, post bookkeeping entries or give legal advice.

Corrected your Finnish tax return? Wait before paying residual tax

Vero tells taxpayers who corrected their return to await the new assessment decision before paying residual tax. The replacement decision sets the amount and payment dates.

Taxpayers who have corrected their Finnish tax return should wait for a new tax assessment decision before paying residual tax, according to Vero’s instructions. The new decision records the outcome after the corrections have been processed, including any residual tax and its due dates or any refund and its payment date.Vero

A correction can therefore affect the payment information in the decision originally supplied with the pre-completed return. Vero expressly tells taxpayers in this situation not to pay residual tax until they receive the replacement decision.Vero The instruction concerns a return that has been corrected; taxpayers who made no changes and whose assessment receives no other changes continue to use the original decision, tax certificate and payment information.

A new decision can also follow changes to a spouse’s return or information received from elsewhere, such as corrected employer data. Vero sends replacement decisions between May and October after processing the information. Decisions are issued at different times, and the taxpayer cannot bring the processing date forward by contacting the authority.

The decision is available in MyTax.Vero How the taxpayer is notified or receives correspondence depends on their digital communications arrangements, including Suomi.fi messages; those receiving paper correspondence get the decision by post. Taxpayers should check the decision’s assessment end date as well as its payment details. The deadline for submitting the tax return and the date on which an individual’s assessment ends are different dates.

A preliminary tax calculation also needs to be distinguished from an assessment decision. Vero provides a preliminary calculation where it still lacks information needed to complete the assessment, for example concerning business, agricultural or rental income or capital gains. Residual tax should not be paid on the basis of that preliminary calculation.Vero The taxpayer must supply the missing information and use the subsequent assessment decision for the final payment details.Vero

The procedural basis is Vero’s guidance on the tax assessment decision and tax certificate, “Verotuspäätös ja verotustodistus”.

If you corrected your return, wait for the new tax assessment decision before paying residual tax.
