Tax forms remain one of the biggest pain points in investor onboarding — slowing down subscriptions, creating errors, and frustrating investors and managers alike, writes Robin Silverthorne, Managing Director, Global Tax Services. Sonata One’s Automated W-Form Solution tackles the problem head-on, replacing clunky processes and repeated requests with a single, seamless workflow that saves time, reduces risk, and makes investing frictionless.
Tax forms present a perennial challenge when it comes to investor documentation. Over the many years I’ve worked in the investor tax space – whether in banking, wealth management, retail or private funds – there’s a phrase I find myself coming back to repeatedly: You can lead a horse to water, but you can’t make it drink.
Anyone involved in investor onboarding or tax form collection will know exactly what I mean. The investor onboarding experience is often frustrated by the difficulties of obtaining documentation quickly and accurately.
Expert guidance and user-friendly technology help but the reality is that even with the right tools and support, investors don’t always provide the information you need to deadline (whether it’s for fund subscription, KYC or tax) or repeatedly make mistakes in completing those forms.
Tax forms – where investors get stuck
Amid full inboxes and competing priorities, busy investors don’t have the bandwidth to digest complex requests or complete lengthy forms. This inevitably leads to delays and errors – particularly with tax forms.
The challenge is compounded by clunky processes involving multiple platforms, repeated requests for the same information, and inconsistent formats across providers. All of which add friction and slow progress.
Take the US W-form journey as a classic example. It’s common for investors to make several attempts before submitting a completed form. Frequently, forms come back incomplete, incorrect, or missing key supporting information, sparking time-consuming back-and-forth.
The result? Inefficiency and delays, higher operating costs, and in some cases, unnecessary US withholding tax deductions. Meanwhile, investors are left frustrated, when all they really want to do is invest – and reinvest – quickly and simply.
Rethinking the process
The data required for fund subscriptions, KYC, and tax reporting is largely the same — yet investors are still asked to provide it repeatedly across multiple funds. With Sonata One, investors authenticate once on a single platform and re-use their pre-approved data across every investment, removing the frustration and delays of repeated verification.
Automation in action
Our Automated W-form Engine takes existing investor information and pre-populates the correct W-form. The investor simply reviews the form, and signs electronically via DocuSign.
If something is missing – for example, an out-of-date KYC detail – our user interface makes it simple to update information as part of the same workflow.
The benefits are clear on both sides. For managers, the process becomes faster, more efficient, and more reliable. For investors, the friction disappears: they can focus on what matters most – making their investment – rather than wrestling with forms.
And because the entire process sits within a single platform, supported by intuitive dashboards and expert human oversight, all documentation is kept current, accurate and visible in real time.
From water to drinking
The lesson is clear: while getting investors to complete forms correctly and on time will always be a challenge, you can design a process that ensures:
- No more repeat requests for the same information.
- No more resubmissions due to errors or incomplete forms.
- No more unnecessary withholding tax deductions caused by missing documentation.
Getting it right the first time creates a smoother investor experience at every stage of the journey, accelerates fundraising, reduces compliance risk, and eliminates avoidable costs and delays.
We’re no longer just leading the horse to water — we’re making it far easier for them to take the drink.
