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.

Wrong CDSI reference may pay another tax bill; hub can move it

Each CDS declaration carries its own 16-character CDSI reference; quoting it wrong delays clearance of goods or diverts the payment, now recoverable via the National Clearance Hub.

Importers who pay duty for Customs Declaration Service declarations must quote the full, correct 16-character reference beginning CDSIGOV for that declarationGOV, and a wrong number now carries two stated risks: the goods are delayed in clearance, or the payment is used to pay a different tax bill the payer owesGOV. Where a payment has paid the wrong bill, the payer can contact the National Clearance Hub to ask for the payment to be moved.GOV

Each declaration made through the Customs Declaration Service generates its own reference numberGOV, so a trader with several declarations holds a different CDSI number for eachGOV. The reference is issued when the declaration is made. Payment can be made straight away after declaring. Where the payment deadline falls on a weekend or bank holiday, the payment must reach HMRC by the end of the previous working day. Missing the deadline can bring a penalty, interest, or both.

Online payment runs through bank-account approval or debit and corporate credit card, with a non-refundable fee for corporate cards and no personal credit cards. An online payment counts as accepted on the date it is made, not the date it reaches HMRC's account, including weekends and bank holidays. Card details entered must match those the bank or card provider holds, including the registered billing address. Bank transfers by CHAPS or Faster Payments can be submitted the same or next day; Bacs needs three working days to reach HMRC, and traders check their bank's processing times and transaction limits first. UK-account payers use sort code 08 32 10, account 14077970 in the name HMRC Customs Duty Schemes; overseas payers use IBAN GB16 BARC 2005 1723 3725 45 with BIC BARCGB22 in the same account name, paying in sterling. Cheques go to HMRC CDS Accounting in Salford, payable to HM Revenue and Customs only with the reference on the back, and must be bank-guaranteed or clearance of the goods may be delayed.

A trader who spots a wrong reference checks whether the goods are held up or the money has landed against another liability, then contacts the National Clearance Hub to have a misapplied payment movedGOV. The hub is also the contact for problems making a payment and for help or advice on the process.

The position is as stated in the GOV.UK guidance on paying for imports declared using the Customs Declaration Service, including the National Clearance Hub contact.GOV

Quote the declaration-specific CDSI reference in full on every CDS duty payment, and if money lands on the wrong bill ask the National Clearance Hub to move it.
