WIA-uitkering (IVA / WGA)

The Dutch long-term incapacity benefit (Dutch WIA-uitkering, short for Wet werk en inkomen naar arbeidsvermogen) is the statutory income-replacement and reintegration scheme that takes over from the employer's two-year continued-payment obligation and from the Ziektewet vangnet once a worker has been incapacitated for 104 weeks. It replaced the older Wet op de arbeidsongeschiktheidsverzekering (WAO) on 29 December 2005, with effect from 1 January 2006, after years of political debate about the unsustainable inflow into WAO and the perception that the old scheme paid people to leave the labour market rather than to return to it. The official short name of the new act is Wet WIA, and its full text is set out in the Staatsblad 2005, nr. 572.

The Wet WIA is administered by the Uitvoeringsinstituut Werknemersverzekeringen (UWV), the same public body that runs the Ziektewet, the Werkloosheidswet (WW), the Wajong, and the Toeslagenwet on behalf of the Ministry of Social Affairs and Employment (Ministerie van Sociale Zaken en Werkgelegenheid, SZW). Within UWV the decisive professional staff are the insurance physicians (verzekeringsartsen), who carry out the medical examination and produce the functionele mogelijkhedenlijst (FML, list of functional possibilities), and the labour experts (arbeidsdeskundigen), who translate the FML into a percentage loss of earning capacity by comparing the worker's residual capacity against a database of theoretically suitable jobs (CBBS — Claim Beoordelings- en Borgingssysteem). Their joint assessment, the so-called WIA-beoordeling, is the legal trigger for entitlement.

The purpose of WIA, as set out in Artikel 4 of the Wet WIA, is dual: to replace lost income for workers who can no longer earn their previous wage because of illness or disability, and to activate residual earning capacity wherever it exists. That dual purpose is reflected in the structure of the law itself, which splits WIA into two strictly separate branches. The first is IVA (Inkomensvoorziening Volledig Arbeidsongeschikten) under Artikelen 47-53, for workers who are at least 80 percent incapable of work and whose incapacity is medically duurzaam (durable, with no reasonable expectation of recovery). The second is WGA (Werkhervatting Gedeeltelijk Arbeidsgeschikten) under Artikelen 54-64, for workers who are partially incapacitated (35 to 80 percent) or who are fully incapacitated but not yet durably so.

This bifurcation is the signature reform of the 2006 law. Under the old WAO, every incapacitated worker entered the same regime regardless of the prognosis. Under WIA, the prognosis is decisive: full and durable incapacity opens the door to IVA, which is a true pension-style benefit paid at 75 percent of the dagloon until AOW-leeftijd (state pension age); anything else opens the door to WGA, which contains powerful activation mechanisms designed to reward residual work effort and to penalise the absence of it. The Wet WIA also rests on a layered structure that connects to other statutes: it picks up where Artikel 7:629 BW (the Dutch Civil Code's two-year wage-continuation rule) and the Ziektewet leave off, it can be supplemented by the Toeslagenwet if the household falls below the social minimum, and it gives way to AOW on retirement age. EU citizens, Polish, Romanian, Bulgarian, Turkish, Bosnian and Arabic-native workers with a Dutch employment history are entitled to WIA on identical terms to Dutch citizens, by virtue of EU Regulation 883/2004 on the coordination of social-security systems and the bilateral conventions the Netherlands maintains with several non-EU states.

Eligibility for the Dutch WIA-uitkering is gated by a single, highly formal moment in the worker's illness trajectory: the WIA-beoordeling after 104 weeks of certified incapacity for work. That 104-week threshold is set in Artikel 23 of the Wet WIA and corresponds exactly to the maximum duration of the employer's continued-wage obligation under Artikel 7:629 BW (the Loondoorbetalingsverplichting bij ziekte) and of the Ziektewet vangnet. The legislative design is deliberate: the public long-term scheme only opens when the private and short-term protections have been fully exhausted, so that employers have a full two-year window to attempt reintegration through the Wet Verbetering Poortwachter (WVP) framework before the case is handed over to UWV's long-term carrier.

The substantive eligibility test is a minimum 35 percent loss of earning capacity. The worker's residual earning capacity is calculated by the UWV labour expert (arbeidsdeskundige) using the CBBS database of theoretically suitable jobs: the labour expert selects three suitable functions matching the worker's FML profile, takes the median wage of those functions, and compares it with the worker's previous wage. The percentage difference — capped at 100 percent — is the official arbeidsongeschiktheidspercentage. Workers who score below 35 percent fall under the so-called WGA-uitsluiting: they receive no WIA benefit, and the legal expectation is that they return to work, in adapted form or with the same employer, who keeps a reintegration obligation for at least five more years.

Above the 35 percent threshold, the worker is sorted into one of two streams. The IVA stream is reserved for workers whose incapacity is at least 80 percent and is medically duurzaam, meaning that no meaningful recovery is expected within the next five years. The durability test is the toughest part of the IVA gate: the UWV insurance physician (verzekeringsarts) must conclude, on the basis of treatment history, prognosis, and medical literature, that improvement is highly unlikely. The IVA criterion was tightened by the 2008 Wet versterking IVA amendments and by case law of the Centrale Raad van Beroep, which clarified that even a small but realistic chance of recovery is enough to deny IVA and route the worker into WGA instead. Many IVA refusals are converted into IVA grants only after a successful bezwaar (objection) or appeal.

The WGA stream covers everyone else above the 35 percent threshold: partial incapacity (35-80 percent) regardless of durability, and full incapacity (≥80 percent) where durability is not yet established. WGA is further sub-segmented internally: workers receive first the loongerelateerde uitkering (LGU, wage-related phase) and then either the loonaanvulling (top-up phase, for those who exploit their residual capacity) or the vervolguitkering (lower follow-up phase). Beyond the 35 percent threshold and the IVA/WGA sorting, there are general insurance requirements: the worker must have been insured under the werknemersverzekeringen at the start of the illness (most employees and many uitzendkrachten qualify automatically), the incapacity must be certified by UWV's own physician — not merely by the family doctor — and the worker must have complied with the reintegration obligations during the prior 104 weeks. Failure to comply with WVP obligations can result in a loonsanctie, which extends the employer's continued-pay obligation by up to 52 weeks before WIA opens.

The amount you receive under the Dutch WIA-uitkering depends entirely on which of the two streams you fall into — IVA or WGA — and, within WGA, on which phase you are in and whether you are exploiting your residual earning capacity. The reference base in all cases is the dagloon (daily wage), calculated by UWV from the worker's most recent refertejaar (reference year) in the central wage register (polisadministratie). The dagloon is itself capped at the maximum dagloon, which for 2025 stands at €280.06 gross per day, corresponding to roughly €6,090 gross per month and around €73,000 gross per year. Earnings above the cap do not feed into the WIA calculation.

Under IVA (Inkomensvoorziening Volledig Arbeidsongeschikten), set out in Artikel 51 of the Wet WIA, the benefit is a flat 75 percent of the dagloon, paid until AOW age (state pension age, currently 67 years and 3 months in 2025 and rising). IVA functions essentially as a long-duration disability pension: there are no further activation phases, no top-up logic, and no follow-up reductions, because the worker is by definition deemed unable to return to meaningful work. A worker who earned the maximum dagloon and is granted IVA therefore receives roughly €4,567 gross per month for the rest of their working life. If the IVA payment falls below the social minimum, the household can apply for a Toeslagenwet supplement.

Under WGA (Werkhervatting Gedeeltelijk Arbeidsgeschikten), set out in Artikelen 59-62 of the Wet WIA, the structure is more complex and explicitly designed to reward work. The first phase is the loongerelateerde uitkering (LGU), which pays 70 percent of the dagloon minus any earnings, with a higher 75 percent for the first two months. The duration of the LGU depends on the worker's work history (arbeidsverleden): a minimum of 3 months and a maximum of 24 months, with one extra month of LGU added for every additional year of work history beyond the first ten years. Workers with a long and continuous career thus get up to two years of generous wage-related benefit, mirroring the WW structure.

When the LGU ends, the worker falls into one of two follow-up tracks. If they are exploiting at least 50 percent of their residual earning capacity — that is, if they are working and earning at least half of what they could theoretically earn given their FML — they receive the WGA-loonaanvulling, which tops their actual wages up to 70 percent of the original dagloon (or higher, depending on the configuration). This is the activation incentive: the harder the worker works, the closer the total household income remains to the pre-illness baseline. If they are not exploiting at least 50 percent of residual capacity, they instead fall to the WGA-vervolguitkering, calculated as 70 percent of the legal minimum wage times the official incapacity percentage. The vervolguitkering can be dramatically lower than the loonaanvulling — for a worker assessed at 50 percent incapacitated, it amounts to only 35 percent of the minimum wage, often well below the household social minimum, in which case the Toeslagenwet supplement again kicks in. Throughout the WGA, UWV conducts an annual reassessment (herbeoordeling) by a verzekeringsarts, which can move the worker between the streams or even into IVA if the durability test is later met.

The application procedure for the Dutch WIA-uitkering is centralised through UWV (the Uitvoeringsinstituut Werknemersverzekeringen) and is in principle fully digital, although a substantial amount of medical and labour-expert assessment work happens in person at one of UWV's regional offices. The timing of the application is strictly fixed by statute: under Artikel 64 of the Wet WIA the worker must file the Aanvraag WIA-uitkering no later than week 93 of the 104-week incapacity period, that is, approximately 11 weeks before the employer's continued-pay obligation ends. UWV sends a reminder letter around week 87, but the legal responsibility to file on time rests with the worker. Missing the week-93 deadline does not automatically forfeit the WIA right, but it can create a payment gap between the end of the employer's wage-continuation and the start of the WIA benefit.

The practical first step is to log in to uwv.nl with DigiD, the Dutch national digital identity, navigate to Mijn UWV, and open the form Aanvraag WIA-uitkering. The worker fills in personal data, BSN (citizen service number), the date of first incapacity, contact details of the employer (or last employer in vangnet cases), the treating GP (huisarts) and any specialists, and uploads the supporting documents. The two most important attachments are the re-integratieverslag (reintegration report) compiled jointly by the employer and the arbo-dienst (occupational health service) under the Wet Verbetering Poortwachter, and any recent medische dossier material from the treating doctors. The reintegration report contains the probleemanalyse, the plan van aanpak, the eerstejaarsevaluatie, and the actuele evaluatie at week 91-93, and is judged by UWV before the actual WIA decision is taken; a deficient report can trigger a loonsanctie against the employer rather than a denial of WIA.

Once the application is filed, UWV opens a file, assigns a case manager (klantmanager), and schedules two appointments: one with the verzekeringsarts for the medical assessment and the production of the functionele mogelijkhedenlijst (FML), and one with the arbeidsdeskundige for the calculation of the loss of earning capacity using the CBBS database of suitable functions. Each appointment can take an hour or longer. The combined output of these two professionals — the WIA-beoordeling — is sent to the worker as a written besluit (decision) typically within six to eight weeks of the appointments. The decision states the percentage of incapacity, the stream (IVA, WGA, or WGA-uitsluiting), the dagloon, the start date, and the duration of any LGU phase.

Throughout the WIA the worker has obligations: cooperate with annual reassessments by the verzekeringsarts, accept passende arbeid (suitable work) offered by the employer or via the labour expert, comply with reintegration steps and any retraining recommendation, be available for medical examinations, and notify UWV of any change in earnings or circumstances within seven days. Failure to comply can lead to a maatregel (sanction), a temporary suspension, or, in serious cases, recovery of paid benefits. Decisions of UWV — granting, refusing, downgrading, or terminating the benefit — are formal besluiten under the Dutch General Administrative Law Act (Algemene wet bestuursrecht) and can be challenged by bezwaar (objection) within six weeks, then by appeal to the rechtbank and, ultimately, by higher appeal to the Centrale Raad van Beroep. Free social-law advice on WIA is available via the Juridisch Loket, the trade unions (FNV, CNV, De Unie), and subsidised legal aid through the Raad voor Rechtsbijstand. Migrant workers can additionally use the multilingual WIA checklist of Buronia at www.buronia.com/nl, which guides the worker step by step through the week-93 deadline, the reintegration-report requirements, the verzekeringsarts appointment, and the bezwaar window.

Comparing the Dutch WIA-uitkering with long-term incapacity schemes elsewhere in Europe is revealing: the Netherlands has, since the 2006 reform, occupied a deliberately activating position, with one of the highest medical thresholds in Europe (≥35 percent loss of earning capacity) and a sharply differentiated payment structure that pushes partially incapacitated workers to keep working. Most other major EU member states still operate single-stream disability pensions with lower entry thresholds, broader eligibility, and weaker activation logic — the very profile the Dutch reformers walked away from when they replaced WAO with WIA.

In Germany the equivalent benefit is the Erwerbsminderungsrente, paid by the Deutsche Rentenversicherung under §§ 43, 240 SGB VI. The German threshold is much lower than the Dutch: a worker who can still work between 3 and 6 hours per day on the general labour market receives the half rate (teilweise Erwerbsminderung), and a worker who can work less than 3 hours per day receives the full rate (volle Erwerbsminderung). The replacement rate is roughly 34 percent of pre-illness gross earnings at the median — significantly below the Dutch 70-75 percent of dagloon. Germany also requires a minimum insurance record of 5 years, with at least 3 of those years of contributions in the last 5 years before incapacity.

In France the comparable scheme is the pension d'invalidité, paid by the Caisse primaire d'assurance maladie (CPAM) under articles L341-1 et seq. du Code de la Sécurité sociale. The French scheme has three categories: Category 1 (able to do some work) pays 30 percent of the reference wage, Category 2 (unable to do any work) pays 50 percent, and Category 3 (unable to work and requiring third-party assistance) pays 50 percent plus a constant attendance allowance. The reference wage is averaged over the worker's ten best years, capped at the plafond de la Sécurité sociale. The headline rate of 30-50 percent is much lower than Dutch IVA (75 percent) or WGA-loonaanvulling (effectively 70 percent topped up).

In Belgium the long-term incapacity benefit is invaliditeitsuitkering, paid by the worker's mutual sickness fund (mutualiteit) from the second year of incapacity onwards. The replacement rate is among the most generous in Europe: 65 percent of the capped wage for the head of household, 55 percent for a single person, and 40 percent for cohabitants. Belgium therefore pays a higher headline rate than the Netherlands at the IVA-IVA comparison but has no formal bifurcation between durable and non-durable incapacity, and no parallel activation track akin to the Dutch WGA-loonaanvulling. In Austria the benefit is Invaliditätspension / Berufsunfähigkeitspension, paid by the Pensionsversicherungsanstalt under §§ 254-255 ASVG; the replacement rate depends on the worker's contribution years and assessed pension base, and typically lands between 35 and 60 percent of pre-illness wages.

In Sweden the relevant benefits are sjukersättning (for those aged 30+ with permanent incapacity) and aktivitetsersättning (for those aged 19-29), both paid by Försäkringskassan under the Socialförsäkringsbalken. The income-related part replaces approximately 64.7 percent of the SGI (sickness benefit base), capped at SEK 30,857 per month in 2025. Sweden, like the Netherlands, has dual streams and emphasises reintegration, but Swedish thresholds are stricter on permanence and looser on partial incapacity. The overall picture is that the Dutch WIA pays one of the highest headline replacement rates in Europe (75 percent IVA, 70 percent WGA wage-related), conditions on a relatively high incapacity threshold (35 percent), and is more sharply activated than any of its continental neighbours through the WGA loonaanvulling/vervolguitkering split.

The Dutch WIA-uitkering does not operate in isolation — it is the long-term endpoint of a layered social-insurance architecture, and the worker's actual household income depends on how WIA combines with, or feeds into, a number of related schemes. Understanding these neighbouring benefits is essential, because the wrong scheme is regularly invoked at the wrong moment and the worker then loses weeks or months of income in the gap.

The most important upstream benefit is the Ziektewet (ZW), the sickness benefit that covers the first 104 weeks of incapacity for vangnet groups — uitzendkrachten, workers whose fixed-term contract ends during illness, recently unemployed workers within the four-week nawerking window, pregnant women with maternity-related illness, organ donors, and no-riskpolis workers. ZW pays 70 percent of the dagloon for up to 104 weeks and is administratively the gateway to WIA: at week 91-93 of the ZW (or of the employer's loondoorbetaling for regular employees), UWV automatically schedules the WIA-beoordeling. For regular employees not in a vangnet group, the upstream rule is not ZW but the employer's two-year continued-wage obligation under Artikel 7:629 BW, capped at 70 percent of wages but typically topped up to 100 percent in year one and 70 percent in year two by collective labour agreement (cao).

The Wajong (Wet arbeidsongeschiktheidsvoorziening jonggehandicapten) is the parallel disability scheme for people who became incapacitated before their 18th birthday or while studying. Wajong is administered by UWV but is structurally separate from WIA: it has no 104-week qualifying period, no work-history requirement, no dagloon (it is paid as a percentage of the minimum wage), and a different activation logic since the 2015 Participatiewet reforms. A worker who has both a Wajong record and later WIA-relevant employment will, in most cases, be sorted into WIA rather than Wajong if their later work record meets the WIA criteria.

The AOW (Algemene Ouderdomswet) — the Dutch state pension — replaces WIA on the worker's AOW-leeftijd, currently 67 years and 3 months in 2025. IVA and WGA both end automatically on that day, and the worker transitions into AOW administered by the Sociale Verzekeringsbank (SVB). The transition does not require a new application: SVB writes to the WIA recipient several months in advance. The household replacement rate at the AOW transition can drop sharply, especially for high-earning WIA recipients, because AOW is a flat-rate national insurance benefit not linked to previous wages; supplementary occupational pension via the pensioenfonds is the standard way Dutch households bridge the gap.

The Toeslagenwet (TW), administered by UWV in parallel with WIA, is the means-tested top-up that ensures the household reaches the Dutch social minimum if the WIA payment alone is too low. The TW is especially important for WGA-vervolguitkering recipients, whose benefit can fall well below the minimum. The IOAZ (Inkomensvoorziening Oudere en gedeeltelijk Arbeidsongeschikte gewezen Zelfstandigen) and IOW schemes are narrow safety-nets for older partially incapacitated former self-employed workers and older WW/WGA recipients whose entitlement has run out. Finally, several non-cash schemes round out the support landscape: the Wet langdurige zorg (Wlz) and the Zorgverzekeringswet (Zvw) cover medical and long-term care, the Wmo (Wet maatschappelijke ondersteuning) provides home help and mobility aids through the municipality (gemeente), and CAO-based supplementary disability cover (WIA-excedentverzekering and WGA-hiaatverzekering) frequently lifts the actual paid amount to 70-80 percent of the worker's full pre-illness wage in sectors such as healthcare, education, and construction.

The Dutch WIA-uitkering is one of the largest single income-replacement schemes in the Netherlands by both head-count and budget, and its caseload has been growing steadily since the 2006 reform. According to UWV's Kwantitatieve informatie and Kerncijfers WIA publications, the active WIA caseload at end of 2024 stood at approximately 190,000 active cases across the European Netherlands, of which roughly 85,000 were in IVA and 105,000 were in WGA. The annual inflow into WIA has risen from about 32,000 new awards per year in the early 2010s to more than 56,000 per year in 2023 and 2024 — driven by population ageing, the long tail of post-COVID incapacity, the rise in psychological complaints (especially burn-out and overspannenheid), and the persistent labour-market pressure on lower-skilled and physically demanding work.

Inside the WGA stream, the typical case duration is now around 6.8 years, calculated as the median elapsed time between WGA grant and exit (recovery, transition to IVA, retirement onto AOW, or death). Within that 6.8-year window, only a minority of WGA recipients return to fully self-supporting work; UWV's own outflow-to-work figures hover between 4 and 6 percent per year for the WGA caseload as a whole, somewhat higher in the first two years after the LGU and noticeably lower thereafter. The WGA-uitsluiting group (less than 35 percent incapacitated, no benefit) numbers an additional 25,000-30,000 cases per year, many of whom transition to WW or to part-time work with employer-led reintegration.

The financial scale of WIA is substantial. Total annual expenditure on IVA and WGA combined was approximately €11.5 billion in 2024, funded by the Werkhervattingskas (the WGA fund, financed by employer differentiated premiums) and the Arbeidsongeschiktheidsfonds (the IVA fund, financed by the basic premium), both ring-fenced within the werknemersverzekeringen budget. The differentiated WGA premium is one of the strongest financial incentives in the Dutch system for employers to invest in prevention and reintegration, because a higher WGA inflow from a given employer translates directly into a higher premium for that employer over a ten-year horizon.

The policy outlook is dominated by three pressures. First, the backlog of WIA-beoordelingen: UWV's verzekeringsartsen are critically short-staffed, and the waiting time for an initial assessment has stretched well beyond statutory norms, leading the cabinet in 2023 to authorise the use of vereenvoudigde beoordeling (simplified assessment) for older claimants. Second, the rise in psychological-cause inflow: more than 40 percent of new WIA awards in 2024 had a primary psychological diagnosis, raising questions about prevention, occupational health, and the role of CAOs and employers in reducing burn-out before the 104-week clock expires. Third, the WIA-evaluatie commissioned by the Ministry of Social Affairs and Employment in 2023-2024 has put several structural questions back on the political agenda, including the level of the 35 percent threshold, the harshness of the WGA-vervolguitkering, the durability test for IVA, and the future of the WGA-hiaat as a cao-supplemented gap. Several reform tracks are under discussion in 2025-2026: lowering the 35 percent threshold, easing the IVA durability test, and introducing a permanent simplified assessment for claimants over 60. Whatever the outcome of those debates, the WIA's central position in the Dutch social-protection architecture is secure — for the foreseeable future it remains the single most consequential benefit decision in any Dutch worker's life after 104 weeks of incapacity, and the WIA-aanvraag is the single most important administrative form a long-term sick worker will ever submit through Mijn UWV.
