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.

Jersey employers of every payroll size can now use Revenue Jersey’s ITIS effective rate wizardGOV to obtain employees’ current tax rates and Social Security contribution liability status. The service replaces the ITIS rate upload previously restricted to large employersGOV, giving smaller payrolls access to the employee-information service.

The wizard works from the employee list in the latest combined employer return received by Revenue JerseyGOV. It draws on the latest information available in the revenue system, gets current ITIS effective rates and Social Security contribution liability status, and identifies changes since the previous combined employer return. Employers can download an extract for use in payroll processing.

The former upload service required an employer with at least 50 employees to supply a CSV file of employee identifiers and payroll details, which Revenue Jersey returned populated with current ITIS rates. The new guidance describes a service available to all payrollsGOV and based on the employee list already supplied through the combined return.

New starters remain a separate step: Revenue Jersey says they must still provide their latest ITIS effective rate notice and Social Security registration card when they startGOV. Payroll teams should therefore retain that onboarding check when incorporating the wizard’s downloaded information into their processing.

For return preparation, the employee’s Tax Identification Number is shown on the effective rate notice and the Social Security number on the registration card. The return records both the tax deducted and the effective rate applied. If more than one rate was used during a month, the online return allows the employer to select the multiple-rate option and enter the actual total deducted instead of the automatically calculated figure.

Technical questions about the wizard can be sent to CER@gov.je. Revenue Jersey’s combined-return instructions are the operational guidance for the service; the legal basis for employer deductions is the Income Tax (Jersey) Law 1961, Article 41B (duty of employer to deduct tax) and Schedule 1A, Part 1, paragraphs 2 and 3 (combined rates and long-term care deductions).

Use the ITIS effective rate wizard to check employee rates and contribution status for payroll processing, while continuing to collect new starters’ rate notices and registration cards.
