IRS MAKE A PAYMENT REDESIGN

Transforming a rigid checkout feature serving over 13M users into a flexible, multi-payment process.

Timeline

Role

3 Designers

Scope

UX Design, Prototyping

CONTEXT

On average, 10+ million payments are made using this tool which hasn’t been revamped since 2021. Data showed that users frequently paid within multiple categories (e.g., Balance + Estimated Tax), logging about 100M annual sessions.

01

Time Consuming Loop

To make two separate kinds of payments, users had to complete one and then restart the entire flow. Doing this 3 times triggered the daily session limit.

02

Limited Error Resolution

Errors are most likely to be discovered on the Review page, which required users to continuously press “Back” to edit the information, then forward to reach Review again.

03

Cognitive Overload

Users had to mentally keep track of the payments they’ve entered, while possibly scrolling through numerous amounts of fields to find the exact one they’re paying for.

OUTCOME

SKIP TO ImpacT

10%

increase in full completion rates.

57%

reduction in critical errors before confirmation.

530,000+

users saved from exiting to Direct Pay.

RESEARCH

We leveraged user data from previous studies and conducted competitive analysis on existing cart processes, synthesizing all findings to reveal a disconnect between the current design and user/industry expectations.

01

Users align the Individual Tax Account & IRS with a financial institution model.

02

Users experience increased stress when dealing with the IRS and committing errors in tax payments is flagged as a high-stakes concern.

03

Industry standards prioritize flexibility, control and easy to grasp design, allowing customization with steps & edits at various points of the flow.

IDEATION

First our team started out with paper sketches to quickly come up with various layouts & ideas. Then, we moved onto low-fidelity wireframes to further visualize and solidify concepts.

How might we implement a checkout experience that is intuitive and flexible for users?

INFormation Architecture

Old Flow

Have to click out to another platform to schedule & start over to make more payments.

New Flow

Brought scheduling into the experience & added more flexibility in the flow for additional payments & editing.

THE SOLUTION

FIX 01

Flexibility

Users can now select multiple payment type options & assign payment dates within a single checkout, giving them more control & saving them time.

Original

Could only select one choice per session. Only at the bottom of the page, did they mention starting over payments at IRS Direct Pay in order to schedule them.

NOW

Users can now add other types of payments as necessary. There is an option to schedule payment dates in each payment card, even expanding to individual payments within a card.

NOW

Payments are separated into individual cards, employing gestalt principles to make the interface more intuitive. The balance table also provides visual feedback, reducing user cognitive load as they enter in their payments.

FIX 02

Grouping & Feedback Visibility

Transformed into a modular card system. The balance table was implemented, providing a clear visual distinction and relinquishing them from tracking responsibility.

Original

Input fields were listed vertically, making it hard to scan and easy to input a payment in the wrong field. Furthermore, there was no feedback tracking what the user entered.

FIX 03

Error Prevention

The original architecture was inflexible for fixing errors. We introduced edit states within the Review step to allow users to fix details then & there, saving them time.

Original

The review page was static, allowing users only to view the information. If making any changes had to go back to a previous step or completely restart.

NOW

Each section is now editable on the review page, allowing users to quickly fix small mistakes or delete payments.

EDGE CASES

Beyond this primary flow, the three scenarios (DDIA, RIA, STIA) were also designed. 7+ edge cases were considered (error states, rare personas). The design has been fully validated for WCAG 2.1 AA & 508 Compliance.

IMPACT

10%

increase in full completion rates.

From review to completion, we see a 5% drop-off rate compared to the previous 15%.


57%

reduction in critical errors before confirmation.

Error rates dropped from 3.7% to 1.6% between Review and Confirmation.


530,000+

users saved from exiting to Direct Pay.

Eliminated click-outs to another app for payment scheduling from 531,199 users to 0.


KEY LEARNINGS

01

I learned that simplifying design explanations into business terms was the key to focusing stakeholder attention, helping us not to navigate off-course into minor details.

02

Bringing the tech team in during the early phases allowed us to identify the API limits early, helping us implement design features to address constraints.

03

Working in tandem on the broader concept, then separating to work on the separate scenarios and concepts made it easier & more efficient as everyone had the same idea & knowledge to build upon.

NEXT STEPS

01

Conduct A/B testing to benchmark the new "Multi-Select" flow against the old "Linear" flow to measure time-saved per task.

02

Moderate 9+ usability sessions to investigate if users understand the new flow intuitively and identify any pain points for a feature state.

03

Make rapid, immediate changes for any critical issues using testing post-launch.
