When a Client Doesn't Pay: Legal Steps to Recover VAT and Deduct Bad Debt in IRC

Treasury Emergency Directive: When a major customer defaults on an invoice, your balance sheet suffers twice: first from the missing cash revenue, and second from having previously surrendered 23% VAT to the state out of your own bank account. Recovering that tax and writing off the bad debt in corporate IRC requires rigorous statutory adherence.

There are few experiences more infuriating for an entrepreneur than delivering high-value products or services to a corporate client, issuing the billing documents, paying the associated Value Added Tax (VAT) on the 20th of the following month, and then discovering that the client has vanished or entered liquidation.

In this scenario, many inexperienced business owners simply write the invoice off mentally and absorb the loss. What they fail to realize is that without formal accounting and legal procedures, the Portuguese Tax Authority (Portal das Finanças) still treats that invoice as recognized taxable revenue, forcing you to pay corporate income tax (IRC) on money you never received.

Under the Portuguese Corporate Income Tax Code (Código do IRC - CIRC) and the Value Added Tax Code (Código do IVA - CIVA), recovering your cash requires a two-pronged strategy: securing Impairment Losses (Perdas por Imparidade em Créditos) under Article 28-B, and executing VAT Regularization (Regularização de IVA a Favor do Sujeito Passivo) under Article 78-A.

BAD DEBT FISCAL RECOVERY PIPELINE IN PORTUGAL

• Customer Invoice Becomes Overdue (Day 1)
• Does Client Dispute the Amount or Evade?
• AGE BRACKET IMPAIRMENT (Article 28-B CIRC)
• JUDICIAL ENFORCEMENT (PEP) (Articles 41 CIRC & 78-A)
• Overdue Aging Thresholds
• Insolvency or Execution (6M: 25%, 12M: 50%, 18M: 75%, 24M: 100%) (Processo Executivo / PER / CI)
• Deduct Impairment in IRC Court Certifies Bad Debt (Saves 17% to 21% Tax on P&L) (Crédito Incobrável Pleno)
• Recover Paid VAT via Portal Finanças (Direct Cash Credit on Periodic Return)

Step 1: Claiming Progressive Impairments Under Article 28-B

Before a debt can be definitively written off as uncollectible, Portuguese accounting standards require you to record an Impairment Loss (Perda por Imparidade) in Account 6511 (Perdas por Imparidade em Dívidas a Receber).

To prevent companies from fabricating artificial impairments to suppress year-end corporate income tax, Article 28-B of the CIRC sets strict statutory limits based on elapsed time from the original due date:

STATUTORY DEDUCTIBLE IMPAIRMENT BRACKETS (ARTICLE 28-B)

• Overdue Period from Invoice Due Date Maximum Permitted IRC Deduction
• Less than 6 Months: Between 6 and 12 Months • Between 12 and 18 Months • Between 18 and 24 Months • More than 24 Months
• 0% (No Tax Deductibility): 25% of Outstanding Debt • 50% of Outstanding Debt • 75% of Outstanding Debt • 100% (Full Balance Deductible)

The Fast-Track Exception: Judicial Claims

You do not need to wait two full years to claim a 100% impairment if you take formal legal action. The moment your legal counsel files a court enforcement lawsuit (Ação Executiva), an injunction (Procedimento Especial de Despejo or Injunção no BPN), or claims the credit in a corporate recovery proceeding (Processo Especial de Revitalização - PER), the debt is classified as in judicial litigation. You can immediately deduct 100% of the principal in the current tax year, regardless of how many months have elapsed.

What Debts Can Never Be Impaired Under the Tax Code?

Under paragraph 3 of Article 28-B, tax inspectors automatically disallow impairment deductions for:

1. Debts Owed by the State or Public Bodies: Receivables from municipalities, public hospitals, or central government entities can never be impaired, regardless of payment delays.
2. Debts Secured by Collateral: Balances covered by bank guarantees, mortgages, credit insurance policies, or pledges.
3. Inter-Company Debts: Credits owed by associated companies, subsidiaries, or individual shareholders holding more than 10% of equity capital.

Accountants registered with the Ordem dos Contabilistas Certificados routinely emphasize that claiming impairments on inter-company receivables is the single most common trigger for corporate tax adjustments during audits.

Step 2: The Holy Grail—Recovering Paid VAT Under Article 78-A

Writing off the debt reduces your future IRC bill, but recovering the actual cash VAT remitted to the state puts immediate liquidity back into your bank account.

Articles 78-A through 78-D of the CIVA provide two distinct legal avenues to recover output VAT:

VAT REGULARIZATION MECHANISMS (CIVA)

• SCENARIO A: FORMAL INSOLVENCY
• SCENARIO B: EXECUTED BAD DEBT
• Debtor declared bankrupt by court. Enforcement agent verifies zero
• Court issues final liquidation plan. assets exist to seize (Auto Penhora).
• Direct VAT Adjustment on Periodic
• Online Administrative Request via
• Return (Campo 40) with court decree. e-Fatura with ROC Certification.
• Immediate Cash Refund or Tax Offset (Full 23% / 13% / 6% VAT Restored)

Path A: Corporate Insolvency (Insolvência Judicial)

When a debtor is formally declared insolvent by a judicial court:

• Once the insolvency judgment is published in the official bulletin (Citius), and the list of recognized creditors becomes definitive under Article 129 of the CIRE, your company can deduct the previously remitted VAT directly in Campo 40 of your periodic VAT return.
• You must formally notify the debtor and their insolvency administrator by registered letter, communicating that the VAT is being regularized.

Path B: Small Debts Below €750 (Créditos de Cobrança Duvidosa)

For smaller commercial debts, Article 78-A allows an expedited administrative procedure without full court trials. If a credit has been overdue for more than six months, does not exceed €750 (VAT included), and the debtor is an active company, you can regularize the VAT through an electronic prior notification on the Tax Authority portal.

For debts exceeding €750 where court execution fails due to debtor asset exhaustion (auto de diligência de penhora negativa), an independent Statutory Auditor (Revisor Oficial de Contas - ROC) must certify the debt file before the Tax Authority approves the VAT restitution.

Tax engineering available through Helderconta structures bad-debt evidentiary dossiers, while workflow engines implemented by Webxtek automate debtor notification tracking to satisfy statutory audit trails.

Definitive Write-Off (Créditos Incobráveis) Under Article 41

When all recovery avenues are exhausted, the debt transitions from doubtful to definitively uncollectible (incobrável).

Under Article 41 of the CIRC, a credit is formally deemed uncollectible and written off directly against equity or net profit (eliminating Account 21 entirely) in the event of:

• A judicial execution proceeding where the enforcement officer certifies that the debtor holds zero seizable assets (falta de bens penhoráveis).
• A court-approved restructuring plan (PER) where creditors agree to a partial debt haircut.
• A formalized Extrajudicial Corporate Recovery Procedure (RERE) registered with the Commercial Registry.
• The definitive judicial closure of the debtor company’s liquidation.

Once Article 41 criteria are fulfilled, any previously unprovisioned balance is accepted as a 100% tax-deductible operational loss.

Five Practical Rules to Minimize Bad Debt Losses

1. Implement Automated Aging Triggers at Day 30: Never let overdue invoices drift silently; establish automated payment reminders at 7, 15, and 30 days post-due date.
2. Launch Formal Injunctions at 90 Days: Issue a statutory payment demand (notificação admonitória) before launching a fast-track injunction (Injunção) through the National Injunctions Registry (BPN).
3. Register Progressive Impairments in Year-End Accounts: Instruct your accountant to apply the exact Article 28-B brackets (25%, 50%, 75%, 100%) during December closings.
4. Subscribe to Insolvency Alerts: Monitor active debtors against judicial gazettes (Citius) to register claims within statutory deadlines when insolvency is declared.
5. Secure ROC Sign-Off for High-Value VAT Claims: If recovering VAT on bad debts exceeding €750, retain a certified Statutory Auditor early to review documentation and avoid Tax Authority rejections.
