Any other updates not listed above
Most updates start around €100–€200 + IVA.
All modification services are strictly administrative. They ensure your data is current with the Spanish authorities but do not replace ongoing tax filing obligations or strategic tax advice. Complex modifications are quoted individually, always with full transparency. For Business closure service our fee covers the formal cancellation of your activity. Please note: This does not include the preparation of your final quarterly tax returns or the settlement of outstanding social security quotas, which must be managed separately. Fee covers the administrative update of your business codes. If the new activity changes your VAT status or tax obligations, a separate consulting session is recommended to ensure full compliance. Official notification of your address change to the Tax Authorities. Ensure your digital certificate is valid, as identity verification is required for this process.
