Fringe Benefits Tax (FBT) can be one of the most frustrating compliance obligations for Australian accounting firms and their clients. With the ATO’s enhanced data-matching capabilities and a sharper focus on FBT audits, there’s increasing pressure to get it right — while still running an efficient practice.
And from 1 July 2025, there’s an added layer: the updated Tax Practitioners Board (TPB) Code of Professional Conduct requires firms to have a signed engagement letter in place before commencing FBT work. That means the old approach of just sending a questionnaire and getting on with it is no longer enough.
This guide outlines a practical framework that transforms the traditionally messy FBT process into a streamlined workflow — including how to get the engagement letter sorted before anything else.
The FBT Challenge
Let’s face it—tracking down car logs, salary packages, and entertainment expenses is time-consuming and prone to errors. The back-and-forth with clients can drag on for weeks, putting pressure on your team and increasing the risk of missed deadlines.
With the right systems in place, you can:
- Eliminate repetitive manual processes
- Automate client follow-up and document collection
- Create protective documentation trails
- Seamlessly integrate with your existing practice management systems
Your 5-Step FBT Transformation Framework
Before You Begin: Get the Engagement Letter Signed
Before you send a questionnaire, chase a logbook, or open a workpaper — get the engagement letter signed.
This isn’t just good practice. From 1 July 2025, the TPB’s updated Code of Professional Conduct requires registered tax agents to have a written engagement in place that covers the scope of services, fees, complaints process, and a number of mandatory disclosures. FBT is no exception.
A compliant FBT engagement letter should cover:
- Scope of services (what’s included and what’s not)
- Fee arrangement and payment terms
- Client responsibilities (logbooks, declarations, timely information)
- Safe harbour explanation
- TPB mandatory disclosures — conflicts of interest, referral arrangements, complaints process
- NOCLAR obligations
Getting this signed upfront also protects your firm. If a client fails to provide information and you can’t lodge, you have a documented record of the engagement terms they agreed to.
Free template: We’ve put together a starting-point FBT engagement letter template you can adapt for your firm.
If you’re using Seamlss, you can paste the template straight in and have it client-ready in minutes — with digital signing built in.
Step 1: Set Up Your Internal FBT Process
Purpose: Establish clear responsibilities and workflows before FBT season begins.
Implementation:
Define team roles:
- Admin: Distribute Smart Links/Fetch Forms and track responses
- Client Manager: Handle technical queries and client follow-up
- Partner: Review critical decisions and final sign-off
Create your tracking dashboard:
- Set up a Project View for real-time progress tracking
- Configure integration with your practice management system (XPM/FYI/etc.)
- Establish colour-coded status indicators (Not Started/Awaiting Client/In Progress/Complete)
Set critical timelines:
- Engagement letters sent and signed: Before any FBT work commences
- Fetch Forms distribution: By 28 March 2026
- First follow-up for non-responses: +7 days after distribution
- Final notice to non-respondents: +14 days after distribution
- Internal processing deadline: Minimum 2 weeks before lodgement due date
Step 2: Engage Clients With Smart Forms
Purpose: Quickly identify which clients require FBT services while making compliance easy.
Seamlss includes two ready-to-use FBT Fetch Form templates you can add straight from the template library:
- FBT Screening Form (25 questions) — A quick triage form covering vehicles, entertainment, salary packaging, car parking, expense reimbursements, and more. Send this to all clients first to identify who actually has FBT obligations.
- FBT Workpaper Data Collection Form (54 questions) — A detailed form for clients with confirmed FBT obligations, collecting vehicle odometer readings, logbooks, entertainment breakdowns, receipts, and declarations.
To add these templates to your workspace, see Adding Template Forms in the Seamlss Help Centre.
Smart forms transform your client outreach by:
- Using plain-language questions that clients actually understand
- Showing only relevant follow-up questions based on previous answers
- Enabling document uploads directly within the form
- Automatically notifying your team when submissions are complete

Hi [First Name],
It's that time of year when the Australian Taxation Office (ATO) requires businesses to report on any fringe benefits provided to employees (for the year ending 31 March 2025).
We've simplified the entire process for you.
Instead of confusing paperwork, we've created a smart online questionnaire that:
- Takes just 5-10 minutes to complete
- Only asks questions relevant to your specific situation
- Guides you through exactly what documents to upload
- Helps protect your business from potential ATO penalties

Not sure what counts as a "fringe benefit"? Common examples include:
- Work vehicles used privately by employees
- Certain entertainment expenses
- Employee loans or accommodation benefits
The questionnaire will help clarify these for your situation.

[Your Name]Step 3: Convert Responses to Actionable Tasks
Purpose: Transform client data into structured workflow items.
Process Flow:
Initial Sorting:
- YES responses: Automatically flagged for full FBT assessment
- NO responses: Routed to nil return preparation queue
- UNCERTAIN responses: Flagged for immediate client manager follow-up
Documentation Review:
- Use a Document Checklist to verify all required supporting materials
- Missing documents trigger automated follow-up requests to clients
Workpaper Preparation:
- Generate pre-populated FBT workpapers directly from client responses
- Assign to appropriate team member based on complexity scoring
Schedule Critical Tasks:
- Set calendar reminders for method elections (50/50 split or 12-week register)
- Schedule final review dates and lodgement deadlines
Pro Tip: Configure your dashboard to display response statistics by client group, helping prioritise follow-up efforts.
Step 4: Strategic Client Follow-Up
Purpose: Secure responses from non-responsive clients.
The follow-up phase is critical—each day without client confirmation increases risk. Automation can maintain this process while keeping a personalised approach.
Enhanced Follow-Up Email Example:
Subject: Important: Your FBT deadline is approaching – Action required
Hi [First Name],
We recently sent you an important questionnaire regarding your Fringe Benefits Tax obligations for the year ending 31 March 2025.
Why this matters urgently:
The ATO has significantly increased audit activity in this area, using sophisticated data-matching to identify businesses that:
- Provide company vehicles to employees
- Hold staff functions or entertainment events
- Offer salary packaging arrangements
These potential fringe benefits require proper documentation—even if you ultimately have no FBT liability.
What happens if you don't respond:
- Potential ATO penalties starting at $550 per instance
- Disallowed tax deductions for benefit-related expenses
- Time-consuming audits that disrupt your business
The good news: Our smart questionnaire takes just 5-10 minutes and provides immediate protection.

Simple FBT FAQ for Clients
What exactly is Fringe Benefits Tax (FBT)?
FBT is a tax paid by employers on certain benefits they provide to employees or their associates outside of regular salary and wages.
Why do I need to worry about FBT if I’ve never lodged a return before?
The ATO requires all businesses to assess their FBT position annually. Even if you ultimately have no liability, you need documentation showing you’ve properly evaluated your situation.
What happens if I ignore FBT obligations?
The ATO can impose penalties, disallow related expense deductions, and conduct time-consuming audits of your business.
What are the most common fringe benefits that trigger FBT?
- Company cars available for private use
- Certain entertainment expenses
- Employee loans with reduced or no interest
- Housing or accommodation benefits
- Private health insurance
