Moving from NIE to DNI does not create a new employment or financial life. Your identifier changes, while your affiliation, seniority, contract, account and transaction history should remain. The safest method is to update public records first and then the systems that depend on them.
Reviewed on 27 August 2026. Banks and employers have their own channels and may request additional documents. This guide organises the change; it does not replace entity instructions or individual employment, tax or banking advice.
Before you start
Prepare your DNI, former NIE/TIE, concordance certificate if available, Social Security number (NUSS/NAF), a recent payslip and bank account-holder certificate. Keep secure copies and receipts. Use the exact name and surname order shown on the DNI everywhere.
Recommended order
1. Update Social Security first
Importass expressly offers Change NIE to DNI under personal data. Without electronic identification, its alternative channel may request personal data, a document image and selfie.
Your affiliation number does not change. Social Security defines it as unique, exclusive, common to all regimes and lifelong. Request a variation on the existing NUSS, never a second number. Afterwards, check the personal area and download your employment history or NUSS certificate. If a duplicate appears, request regularisation before the employer reports further changes.
2. Notify the Tax Agency
The Tax Agency states that a person who moves from NIE to DNI must report it with form 030, supported by the new identity document and evidence of the change. Check your census data afterwards. Do not treat a NIF update as an automatic change of address or tax residence; review those fields separately.
Self-employed people or those with a special census position should also verify which declaration their activity requires. Form 030 can cover identification changes but does not replace every business filing.
3. Tell HR or the payroll provider
Use the employer’s secure internal channel and provide the new DNI, old NIE, concordance if requested, exact legal name, existing NUSS/NAF, proof of the TGSS update and the date from which the new identifier should be used.
Ask them to update your existing employee record, not create another worker, contract or Social Security registration. Acquiring nationality and changing identifier do not by themselves reset seniority, contract, holiday, pay or contributions.
HR may need to coordinate payroll, occupational health, mutual insurer, company health cover, pension plan, meal card, employee portal or an external provider.
4. Check the next payslip
Compare it with the previous one: DNI/NIF and full name, NUSS/NAF, employer and role, seniority date, gross pay, contribution bases, income-tax withholding, net amount and payment IBAN. Also inspect holidays, bonuses, advances or garnishments where relevant.
An identity change alone does not explain a pay or tax change. Withholding can vary for another reason; ask payroll for the calculation before attributing it to the DNI.
5. Update the bank without closing the account
Ask the bank to rectify NIE to DNI and update nationality in the existing customer profile. The Bank of Spain explains that banks must identify customers and can request identity/activity documents and periodic updates.
Confirm the bank’s channel and required evidence. Ask for written confirmation that the existing holder was updated; IBAN, balance and history remain; cards, loans, deposits, direct debits and authorised users remain linked; and online access, signature, Bizum and tax reporting are correct. Download a new account-holder certificate once available.
Do not close and reopen an account merely to change the identifier unless the bank explains a system requirement and you understand every consequence. A new account would require changing salary, bills, benefits, refunds and payments.
Do not ignore information requests. The Bank of Spain says persistent failure to provide documentation can justify restrictions, although they should be gradual and proportionate. A bank restriction or closure should normally be communicated with at least a generic reason, subject to legal confidentiality exceptions.
Avoid changing identity and IBAN together
If you also want to move banks, first update the DNI on the salary account, wait for one correct payroll payment, then give HR the new account-holder certificate. Keep the former account open until salary, direct debits and refunds are confirmed. Avoid both changes immediately before payroll cut-off.
If records become duplicated or wrong
Do not create a third profile. Identify the old and new records, provide DNI and concordance, and request rectification and consolidation while preserving history.
The AEPD recognises the right to have inaccurate personal data corrected without undue delay and incomplete data completed. State which data must change and attach evidence where necessary. Use the relevant formal employment, tax or banking complaint route for disputes as well.
