Why should network managers care about the FASTER Directive?

By Ross McGill

Ross is the founder and chairman of TConsult. He has spent over 26 years working in the withholding tax landscape with companies developing tax reclaim software and operating outsource tax reclamation services.

Ross not only sees the big picture but is also incredibly detail oriented. He can make even the most complex issues simple to understand. He has authored 10 books (including two second editions) on various aspects of tax, technology, and regulation in financial services, making him one of the leading authorities in the world of tax.

A chain is only as strong as its weakest link

For network managers in financial services, understanding how your counterparties are handling the FASTER Directive is not simply “another withholding tax initiative”. It’s a test of how well institutions communicate within the full securities chain.

The policy objective of FASTER is to make withholding tax relief and refund processes faster, safer and more consistent across the EU. There are only three components to that idea: (i) establishing an electronic tax residency certificate (eTRC) to replace paper certificates of residency, (ii) establishing an institutional framework using a new classification of “Certified Financial Intermediary” (CFI) as the only types of financial institution in the payment chain capable of delivering tax relief and (iii) establishing a reporting framework to provide Member States with the information needed to recreate the payment chain to prevent abuse. The Directive defines but does not describe the parameters for a “comprehensive relief at source system” leaving the operational aspects entirely to the industry.

The operational reality is more complicated. FASTER relief depends on multiple parties exchanging complete, accurate and timely information, and that’s just the actual tax relief part that’s not addressed by FASTER. The traditional tax relief model has the withholding agent assuming strict liability for tax over or under withheld. Hence that withholding agent at the top of the payment chain needs evidence for each and every recipient of tax relief otherwise statutory tax rates apply. If those parties rely on fragmented instructions, inconsistent data standards and unclear ownership of tax documentation, FASTER will not deliver the efficiencies that policy makers expect.

The part that FASTER does address is reporting of how tax was withheld through the payment chain during the prior month. So, in principle, disclosure takes place twice – once to a counterparty to obtain operational relief and once to the source Member State through reporting. To achieve this, the Directive established the concept of Certified Financial Intermediaries or CFIs and a bifurcated direct or indirect reporting model. In the indirect reporting model, all CFIs in the chain of payment must send their payment and withholding information up the payment chain to the CFI at the top. It’s that CFI who must report to the source Member State’s tax administration – so the whole payment chain is disclosed. In the direct reporting model, each CFI in the chain does its own reporting to the source Member State, so the home jurisdiction gets a fragmented picture of the whole payment chain from which it could, if necessary, re-constitute the entire chain. The issue is that the decision of which reporting model is adopted does not need to be made until transposition of FASTER into domestic law – by December 31st, 2028, leaving just two years for CFIs to configure and test their operational models for each Member State.

This is where network managers have a critical role. They sit at the intersection of custodians, sub-custodians, tax agents, market infrastructures, issuers, brokers, fund administrators and clients. They understand that tax relief is not a single process owned by one party. It is a chain of dependencies. When communication in that chain fails, the result is delayed relief, rejected claims, investor frustration, operational risk and potential financial exposure.

Changing the expectation

Current withholding tax processes often tolerate delay. Relief at source may require manual pre-certification. Refunds may depend on local forms, wet signatures, original tax residence certificates, powers of attorney, market-specific declarations and supporting evidence that varies by jurisdiction. In many cases, the process is slow because it has been designed around exception handling rather than standardisation.

FASTER changes the expectation. Its ambition is to support faster relief at source or quicker refunds through more harmonised procedures, digital tax residence certificates and reporting by certified financial intermediaries. That means institutions will no longer be able to rely on informal workarounds, bilateral interpretations or post-event remediation as the default operating model.

The message for network managers is simple: speed is only possible when communication is structured.

A custodian cannot apply a reduced treaty rate if it receives incomplete investor data. A withholding agent cannot support a quick refund if registered ownership information is unclear. A tax authority cannot validate a claim efficiently if the transaction chain is opaque. An investor cannot benefit from FASTER if the relevant parties cannot agree who is responsible for collecting, validating, transmitting and retaining the required information.

FASTER might create a common framework, but it will not automatically create operational alignment or efficiencies of scale.

Operational dependencies are the real risk

Withholding tax relief depends on a number of operational hand-offs. These include investor classification, residence documentation, declarations, beneficial ownership confirmations, account structure analysis, holding and transaction data, income event information, tax rate determination, reporting and evidence retention.

Each hand-off creates a dependency. Each dependency creates a risk.

The most common failures are rarely caused by absence of process. They are caused by mismatched assumptions. One party believes another has validated the tax residence certificate. One team assumes standing instructions are up to date. A local market agent expects information in a specific format, but the upstream custodian sends a generic file. A client assumes relief at source is available, but the custodian has not confirmed the documentation cut-off. A tax operations team knows the local requirement, but the network management team has not embedded it into the service-level agreement.

These are communication failures disguised as tax technical issues.

Network managers should therefore treat FASTER readiness as a network-wide operating model review. The question is not only whether an institution understands the Directive. The question is whether each relevant relationship, market procedure, data exchange and escalation route can support the Directive in practice.

Lessons from the U.S. QI program

The U.S. Qualified Intermediary regime provides a useful warning. QI has existed since 2001, and many financial institutions have mature U.S. documentation, withholding and reporting frameworks. Yet QI reviews continue to reveal recurring weaknesses: incomplete documentation, expired forms, incorrect client classifications, poor evidence of review, unclear responsibility between front office and operations, and inconsistent controls across booking centres or branches.

These issues are not always caused by a lack of regulatory knowledge. Often, the rules are understood by tax specialists, but the operating model fails to translate that knowledge into reliable day-to-day behaviour. Compliance functions want absolute protection through a rules-based system. Operations functions want the fastest and cheapest way to say the job got done. Cutting corners is a basic tenet of one function but anathema to the other.

In the U.S., reporting is a cascade, each financial institution pooling their own direct clients on forms 1042-S while separately reporting payments and tax withheld on downstream financial institutions so that they in turn can report according to their obligations. Many firms fail to provide so-called “recipient copies” of their information returns 1042-S to their clients at all, or if so, late, not in the correct format or only when chased. This causes major problems in a cascade structure where the IRS is comparing what one party reports against what the other party reports, leading to penalty notices downstream. This is not customer service. It’s not good practice. Its handing your customer a regulatory problem and potential financial penalty – with a smile on your face.

The same risks will exist under FASTER.

A firm may have a strong tax policy but weak communication with its sub-custodian. It may maintain an inventory of market requirements but fail to update client-facing teams when those requirements change. It may collect investor documentation but not link that documentation effectively to positions, income events and treaty eligibility. It may rely on a third party for relief processing but lack sufficient oversight of that third party’s controls.

QI experience shows that withholding tax compliance fails when documentation, data, controls and accountability are not aligned. FASTER will amplify the same problem because it places greater emphasis on speed, data quality and traceability across multiple institutions.

For network managers, the lesson is clear: do not assume that a regulatory framework will compensate for weak operational communication.

Standardisation is not optional

The promise of FASTER depends on standardisation. Without it, firms will simply digitise existing inefficiencies.

Standardisation should apply at several levels.

First, institutions need standardised data requirements. Core data fields such as investor identity, tax residence, beneficial ownership status, account type, intermediary role, income type, security identifier, payment date and applicable treaty rate must be captured consistently. Where data definitions differ between markets or service providers, those differences should be documented and controlled. Interestingly, FASTER does use the concept of beneficial ownership. Instead, FASTER uses “registered owner” as the core component for tax relief. These are not the same thing. For equities, the registered owner would be the nominee, broker, custodian or company listed on the share register, while the beneficial owner would be the investor who is entitled to dividends, gains, voting influence or economic benefit. Most financial institutions today focus on beneficial ownership.

Second, firms need standardised documentation rules. This includes clear requirements for digital tax residence certificates, declarations, eTRC validation codes, validity periods, renewal processes, evidence retention and acceptable alternatives where a standard document is unavailable.

Third, communication with service providers must be standardised. Network managers should not rely solely on market guides, email updates or informal relationship knowledge. Requirements should be embedded into due diligence questionnaires, service descriptions, SLAs, operating memoranda and escalation procedures. The net effect of attempting FASTER (as opposed to letting everything flow to standard refunds) is that penalties will be applied by Member States, CFI status can be revoked in one or more markets

Fourth, internal communication must be standardised. Tax, operations, custody, product, client service, compliance, legal, technology and network management teams need a shared understanding of who owns each part of the process. The absence of internal clarity will quickly become an external service failure. In many tax relief models, the operational components consist of the use of omnibus accounts operated across networks in the payment chain to co-mingle assets of beneficial owners who meet the documentary rules, plus withholding statements that provide legal relief from, or transference of liability with respect to the actions taken in the actual withholding. In FASTER, the concept is that all registered owners will be disclosed ultimately to the source Member State either by the CFI at the top of chain (requiring disclosure from all those below it) or by CFIs within the payment chain. This begs the question of whether the operational efficiency of omnibus accounts is diluted (given that disclosure is mandatory) in favour of registered owner segregated accounts in the payment chain which could then support disclosure through reporting more effectively. These are not small matters.

Standardisation does not remove market complexity, but it makes complexity manageable.

Data quality will determine whether FASTER works

FASTER is often discussed in terms of timelines and procedures, but the practical challenge is data quality.

Fast relief depends on accurate data being available before the income event, not reconstructed after a claim has failed. This requires firms to move from reactive tax processing to proactive data governance.

Network managers should ask whether their institutions can answer the following questions with confidence:

  • Do we know which intermediaries in our custody chain will voluntarily register as CFIs?
  • Do we know which markets will offer truly workable relief at source and quick refund?
  • Do we know what registered owner data is required by each market?
  • Can we identify gaps in documentation before a dividend or interest payment?
  • Can we evidence who validated the data, when it was validated and what source was used?
  • Can we reconcile tax relief claims to positions, payments and registered owner eligibility?
  • Can we monitor whether sub-custodians and agents are meeting agreed processing timelines?

If the answer to these questions is unclear, the institution has a FASTER readiness gap.

Poor data quality not only creates operational delay. It also creates risk. Incorrect relief at source may lead to over- or under-withholding. Unsupported claims may be rejected. Late or inconsistent reporting may increase scrutiny from tax authorities. Clients may challenge service failures where they expected access to treaty benefits.

The cost of poor communication will therefore be measured not only in operational effort, but also in client dissatisfaction and potential financial exposure.

Assumptions make an ass out of you and me

FASTER is not simple. It looks simple in concept, but as soon as you start peeling back layers of operational requirements, you begin to see permutations that, if left unresolved, create substantial operational and compliance risk. FASSTER was passed in December 2024, so we’re already a year and a half into the project with many questions still unanswered (and probably many more that remain unasked). While these will undoubtedly be addressed in due course, making assumptions is a dangerous business. The only real assumption you can make is that, just like distributed ledger technology and AI, the devil will be in the detail.

Industry readiness gaps remain

Many institutions are still treating FASTER as a future regulatory change. That is understandable given the implementation timeline, but it is also risky. The required changes will involve legal analysis, market engagement, data mapping, technology development, contractual updates, client communication and control design. These cannot be completed effectively at the last minute (but I bet that some will try).

Several readiness gaps are already visible across the industry.

Some firms have not mapped their full custody and withholding tax dependency chain. Others do not yet know which entities in their group may want to register as certified financial intermediaries (some firms have no choice). Many firms have not assessed whether their existing tax documentation platforms can support digital tax residence certificates or more structured evidence requirements. Some have not reviewed whether current sub-custodian reporting can provide the level of transparency needed under the new framework.

There is also a governance gap. FASTER does not sit neatly in one function. It is a tax issue, a custody issue, a data issue, a regulatory change issue and a client service issue. Without clear governance, firms risk fragmented implementation, with each team solving only part of the problem. After twenty-three years in this space, we still see the most common root cause as the “silo” effect. Firms think they are well integrated, but they’re really not. FASTER will expose these siloes to a much greater degree than the US QI program has. In that space we still see counterparties failing to meet their obligations to their clients either because the requirement was not embedded into the contract or SLA or because one counterparty just does not care because they aren’t immediately affected.

Network managers can help close this gap by forcing practical questions into the implementation agenda. Which markets matter most to our clients? Which providers are critical to our operating model? Which data fields are missing today? Which processes are manual? Which controls rely on individual knowledge rather than documented procedures? Which client promises are we making today that may not be supportable tomorrow?

These are not theoretical questions. They are the questions that will determine whether FASTER improves the investor experience or simply creates a new layer of operational complexity.

What network managers should do now

Network managers should begin with dependency mapping. Identify every party involved in withholding tax relief and refund processes across key EU markets. Document the role each party plays, the data it requires, the format it uses, the deadlines it applies and the controls it operates.

Next, review communication channels. Market updates, tax matrices and operational notices should be complete, current and accessible. Informal knowledge held by relationship managers should be converted into controlled documentation. Where requirements are unclear, providers should be challenged now rather than after implementation.

Third, assess data readiness. Compare current investor, account, position and income data against likely FASTER requirements. Identify fields that are missing, inconsistently populated or not available in a usable format. Data remediation should be treated as a strategic priority, not a tax operations clean-up exercise.

Fourth, update due diligence and oversight. Sub-custodian and agent reviews should include FASTER-specific questions covering registration intentions, reporting capability, relief procedures, technology readiness, control frameworks and escalation processes.

Finally, align internal stakeholders. FASTER implementation should include tax, operations, legal, compliance, technology, product, client service and network management. The objective should be a single operating model, not a collection of separate workstreams.

Better communication is the foundation

FASTER is designed to make withholding tax relief faster and safer. But the Directive cannot fix poor communication by itself. It will aggressively expose weak links in the custody chain, inconsistent data practices and unclear ownership between institutions.

For network managers, this is both a challenge and an opportunity.

The challenge is that legacy processes will not be good enough. Manual workarounds, fragmented documentation and market-by-market interpretation will struggle under a framework that expects greater speed and transparency.

The opportunity is that network managers are uniquely placed to drive the change. They understand the custody chain. They manage the provider relationships. They see where operational dependencies break down. They can translate regulatory expectations into practical service requirements.

FASTER will reward institutions that communicate clearly, standardise effectively and manage data as a core compliance asset. It will brutally expose those that continue to rely on assumptions.

The firms that succeed will not simply be those that understand the Directive. They will be those that use it as a catalyst to build better communication across the entire withholding tax ecosystem.

As someone once said, insanity is doing the same thing over and over and expecting a different result. The industry needs to wake up and smell the coffee. The opportunity is there to make a real change and stop expecting to keep doing the same thing under FASTER as we’ve always done and expect anything different to what we’ve had before.
