Keep Spanish VAT reporting clean from invoice capture to filing.
Let AI Agent run your tax filing
Map SII Scope
Map the SII-reportable invoice population for the selected Spanish entity in NetSuite. Pull all outbound and inbound invoices for this quarter, classify by VAT type (standard, reduced, exempt, intra-EU, reverse charge), and tag by SII subledger (issued, received, investment, intra-Community). Compare against last quarter's population and flag new VAT codes, new counterparties, and retroactive corrections. Pause before adding any new VAT mapping rule. Send a Slack summary with population count, missing fields, and the next four-day deadline. If the entity's REDEME status is unclear, ask me whether to file as monthly REDEME or quarterly. Ask me where I keep the entity's prior SII submission log.
Submit Sales Invoices
Push this week's outbound invoices to AEAT under the SII protocol for the selected Spanish entity in Sage Intacct. Watch the ledger for newly posted invoices, format the SII XML payload, and submit through the AEAT web service inside the four-day window. Validate the response code and retry on transient errors. Pause before submitting any invoice flagged for VAT-rate review. Return a Slack confirmation with submission ID, AEAT response, and any rejected lines. Ask me to record the firm's threshold for what counts as a high-risk invoice (large amount, new counterparty, intra-EU change) so I can hold those for review.
Match Supplier Bills
Match this quarter's inbound invoices to supplier-side SII records for the selected Spanish entity in QuickBooks Online. Pull the AEAT contraste report, compare each inbound invoice to the supplier's submission, and flag mismatches in date, amount, VAT base, or invoice number. Pause before correcting any inbound record that the supplier has already submitted. Save the contraste pack to Google Drive with mismatched lines, owner, and the response window. Ask me to upload the supplier list with NIFs if it is not in the ledger, and ask me whether the firm wants to chase the supplier or let the discrepancy stand for the next reporting period.
Prepare VAT Return
Prepare the periodic Modelo 303 VAT return for the selected Spanish entity in NetSuite, sourced from the SII submission log. Aggregate output VAT, deductible input VAT, intra-EU acquisitions, and reverse-charge entries by box. Cross-check the totals against the ledger trial balance and flag any drift. Pause before saving the return as final. Save the Modelo 303 workpapers to Google Drive with the SII reference, the trial-balance tie, and the variance memo. Ask me to confirm the entity's filing periodicity (monthly REDEME or quarterly), and ask me where the firm wants the Modelo 303 confirmation archived.
Real-Time VAT, Without the 4-Day Scramble
A four-day reporting window only feels short when the workflow is batch. The agent runs the SII pipeline as a stream: every posted invoice triggers a submission attempt within hours of being entered, with the deadline as a backstop, not a target.
One Spanish Subsidiary, One Calendar
If the firm carries one Spanish subsidiary among many US clients, the team should not rebuild the SII workflow each year. The agent runs the SII calendar alongside US obligations on the same compliance surface, so the work fits inside the existing cadence.
Cross-Border Books That Survive an AEAT Audit
A Spanish entity run from a US ledger sits at the intersection of two control regimes. The agent surfaces every place where a US-style posting would fail Spanish documentation rules, VAT base, NIF format, intra-EU declarations, before AEAT does.
How does Minded support tax filing when SII submissions drive VAT returns?
Minded reconciles invoice populations, SII submission status, and return workpapers so the tax compliance lead can see what is ready, missing, or mismatched before filing. It helps connect transaction-level reporting with VAT return preparation instead of treating SII and tax filing as separate review tracks.
Can Minded help with SII compliance for Spanish entities owned by US groups?
Yes. Minded can help organize sales invoices, purchase invoices, customer data, supplier data, and submission evidence for Spanish entities, including subsidiaries and branches. The accounting team can coordinate with an in-country advisor or manage the workflow in-house while keeping a clear review trail for SII compliance.
How does Minded handle real-time VAT reporting to AEAT?
Minded monitors invoices that need to be reported, checks required fields, flags exceptions, and tracks submission status. It does not replace legal review or the filing authority, but it gives operators a working queue for outbound and inbound invoice reporting tied to AEAT requirements.
Can Minded support VAT compliance across Modelo 303, Modelo 390, and Modelo 349?
Minded helps align SII-reported transactions with VAT return inputs, annual summaries, and intra-EU reporting support. It can surface differences between ledgers, invoice records, and filing workpapers so the reviewer can resolve issues before preparing Modelo 303, Modelo 390, or Modelo 349.
Which accounting systems can Minded use for cross-border VAT workflows?
Minded can work with systems such as NetSuite, Sage Intacct, and QuickBooks Online, plus supporting files from shared drives. It helps normalize invoice data, supplier records, tax codes, and audit trail evidence so cross-border VAT review is less dependent on manual exports and spreadsheet checks.
