The Portugal Revenue Department has processed over 3.2 million individual tax returns by early June, with refunds surpassing €1.7 billion—yet certified accountants warn that thousands of declarations remain stuck in validation limbo, creating friction for self-employed workers and anyone filing beyond the simplified automatic system.
Why This Matters
• Refund speed varies wildly: The IRS Automático pathway delivers money in 11.6 days on average, but complex filings—especially Category B income (freelancers, contractors)—face wait times stretching three to four weeks.
• Over 60% of processed returns qualify for refunds, with nearly 1.95 million taxpayers receiving money back as of June 3.
• The deadline is June 30, and the tax authority has until August 31 to complete payments—meaning delays now could compress summer cash flow for thousands.
The Dispute Between Accountants and Finance Ministry
While Portugal's Ministry of Finance insists the 2026 tax season (covering 2025 income) is running smoothly, the Order of Certified Accountants paints a different picture. Bastonária Paula Franco told national radio that validation has "stopped" for many filers outside the automatic track, leaving "many thousands of declarations unliquidated" and accountants fielding daily pressure calls from anxious clients.
The Finance Ministry counters with hard numbers: as of June 3, 1,814,589 refunds had been paid, representing a jump of 209,000 payments compared to the same date in 2025. The average turnaround for automatic returns dropped from 13 days last year to 11.6 days in 2026, a tangible improvement for the majority.
Yet the ministry declined to address Franco's core complaint—processing times for Category B filers and other non-automatic submissions—or specify median wait periods for those cohorts. That omission leaves a data gap precisely where self-employed residents and micro-entrepreneurs need clarity most.
What This Means for Residents
If you submitted via IRS Automático—the pre-filled form covering wage earners and pensioners—your refund likely arrived in under two weeks. Roughly 3.3 million households fall into this bracket, comprising the bulk of processed returns.
For everyone else, especially the recibos verdes workforce and small-business owners filing Anexo C, D, or F, expect three to four weeks minimum. Common bottlenecks include:
• Invoice mismatches: Expenses logged in the e-Fatura portal that don't align with declared deductions. The February 25 deadline to validate and classify 2025 receipts was critical; mistakes here cascade into processing delays.
• Missing or inconsistent annexes: Household composition errors, amended values, or incomplete supplementary schedules trigger manual review.
• IBAN issues or outstanding debts: An inactive bank account or unpaid levies will freeze disbursement until resolved.
Over 5 million families had filed by mid-June, meaning the tax authority is still working through a significant queue as the June 30 cut-off approaches. Late filers risk pushing their reimbursement into the August 31 legal maximum.
Behind the Numbers: A Two-Speed System
The Portugal tax system now operates on parallel tracks. The fast lane—IRS Automático—leverages employer withholding data and the e-Fatura repository to pre-populate returns, enabling algorithmic approval. For 2026, that pathway accounted for roughly 60% of liquidated declarations, based on the Finance Ministry's disclosure.
The slow lane encompasses Category B income (professional services, freelancing), rental earnings, capital gains, and foreign-source revenue. Each of these demands human or semi-automated scrutiny, and the Autoridade Tributária e Aduaneira (AT) has not disclosed staffing or resource allocation to handle the load.
Paula Franco's assertion that processing "paused" suggests either a workflow choke-point or deliberate sequencing—prioritizing simpler cases to hit early statistics, then batching complex reviews. The Finance Ministry's silence on Category B timelines fuels that speculation.
Historical Context: Refund Volume and Velocity
Portugal paid €1.7 billion in refunds through early June, covering 1.81 million taxpayers. For context, the entire 2025 season eventually processed over 6 million returns, with total refunds exceeding €3 billion. The current pace suggests the AT is on track to match or slightly exceed last year's final tally, provided validation accelerates through the summer.
Average wait times have improved year-on-year for automatic filers—11.6 days versus 13—but the gap between automatic and manual submissions appears to be widening. In 2025, complex returns averaged three to three-and-a-half weeks; anecdotal reports from accountants suggest 2026 filings in that category are trending toward the upper bound or beyond.
The Order of Certified Accountants has responded by publishing its "Essential Collection 2026," a suite of guides covering legislative updates and common pitfalls. The organization also emphasizes taxpayer education around the 1% consignment option, which allows residents to direct a sliver of their tax to social or cultural causes—a feature many overlook amid refund anxiety.
Practical Steps for Taxpayers Still Waiting
If your declaration remains "Em processamento" in the Finance Portal:
Check for divergences: Log into the AT portal and review any validation alerts. Mismatched withholding, duplicate expense claims, or annexes flagged for correction will halt progress.
Verify your IBAN: An outdated or closed account is a silent killer for refunds. Update banking details in the "Perfil" section of the portal.
Confirm e-Fatura submissions: Revisit your 2025 invoice history. Professional expenses claimed on Anexo C must match classifications (professional, personal, mixed) you assigned by February.
Settle outstanding balances: The AT will net any refund against unpaid liabilities. A €500 refund disappears fast if you owe €300 in municipal property tax.
Residents without internet access can book an appointment at a local Serviço de Finanças office for in-person assistance. Digital-only submission ended paper filing, but face-to-face support remains available for those who need guided navigation.
The Broader Fiscal Picture
Portugal's tax administration has invested heavily in digitization over the past five years, and the IRS Automático system represents the flagship outcome. The 2026 season marks another stress test: can automation scale to handle the majority, and can legacy infrastructure support the minority efficiently enough to avoid political blowback?
The dispute between the Finance Ministry and the Order of Certified Accountants underscores a recurring tension. Headline statistics—more refunds, faster processing—look strong. But aggregates mask distribution; if 70% of filers receive their money in two weeks while 30% wait six, the average looks fine even as hundreds of thousands experience meaningful hardship.
For self-employed residents, summer cash flow often hinges on the IRS refund. A €1,200 reimbursement can cover rent, school fees, or estimated quarterly taxes for the next period. Delays compress those margins, and the lack of transparency around Category B timelines compounds the stress.
The AT has until August 31 to close the books on 2026 income-year filings. Whether the current pace accelerates or the backlog persists will shape both taxpayer sentiment and the political conversation heading into autumn budget negotiations.
