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.

« Régularisation mixte »: credits offset remaining dues on Urssaf calendars

After the 2026 social-base reform, a calendar can show debit balances on some risks and credit balances on others. Credits automatically offset remaining 2025 dues; any surplus is reimbursed with no action required.

Self-employed workers who declared their 2025 revenue between April and June on impôts.gouv.fr receive their annual payment calendar in their online accountUrssaf once the tax administration has transmitted the declaration to UrssafUrssaf. On that basis Urssaf computes the final 2025 contributionsUrssaf, adjusts the 2026 provisional contributionsUrssaf and estimates the first 2027 instalmentsUrssaf. The calendar has four pages: general information on the calculations, the new 2026 payment calendar with the estimated early-2027 échéances, the detail of the final 2025 contributions with the resulting regularization, and the detail of the 2026 provisional contributions.Urssaf

A calendar can show a « régularisation mixte »: debit balances on some risks alongside credit balances on others. With the 2026 réforme de l'assiette sociale, the share of CSG-CRDS in the social contributions due has fallenUrssaf while the share of so-called contributory contributions, such as retraite, has risenUrssaf, so this split outcome occurs more frequently.

In a mixed regularization the credit balance is automatically used to pay the social contributions still dueUrssaf: Urssaf recalculates the monthly amounts so the credit reduces the 2025 échéances remaining payable in 2026Urssaf. If the credit exceeds the contributions due, Urssaf reimburses the balance.Urssaf No action is required from the worker.Urssaf

Urssaf illustrates the mechanism with a worked example for 2025 contributions: final contributions of 44 568 € against 49 037 € already called provisionally, giving a net regularization of −4 469 € composed of 1 458 € of debit regularization (maladie 658 €, retraite de base within the 47 100 € limit 57 €, retraite complémentaire within the 47 100 € limit 743 €) and 5 927 € of credit regularization (CSG/CRDS −4 814 €, allocations familiales −432 €, retraite complémentaire between 47 100 € and 188 400 € −611 €, indemnités journalières −69 € and retraite de base beyond 47 100 € −1 €). In that example the 1 458 € debit is spread over the July to December 2026 échéances and 4 469 € is reimbursed.

To read the calendar, the amount left to pay is in the page 2 « Échéances à venir » table, in the « Montant restant à payer en 2026 » columnUrssaf; Urssaf notes that the credit itself is not deducted in that columnUrssaf. A reimbursement is signalled on page 3 by the mention « Vous bénéficiez d'une régularisation créditrice 2025 pour un montant de... »Urssaf. The pages cover artisans-commerçants, professions libérales and praticiens ou auxiliaires médicaux.

Legal basis: the 2026 réforme de l'assiette sociale for travailleurs indépendantsUrssaf, implemented from the 2025 revenue declarationUrssaf by Décret n° 2024-688 du 5 juillet 2024Urssaf.

Check the recalculated July–December 2026 échéances in the page 2 « Échéances à venir » table and verify any reimbursed balance on page 3 — no filing or request is needed.
