Navigating Boarding ATO Rules: A Guide For Australians

If you are offering a room in your home and including services like meals or laundry, the Australian Taxation Office (ATO) considers the money you receive as assessable income. This means it must be declared on your tax return. Understanding the distinction between a simple rental agreement and a formal boarding ato arrangement is the first critical step to ensuring your tax compliance.

This article is based on the Current Financial Year at the time of writing.

Here at Baron Tax & Accounting, our experience with diverse clients across Brisbane shows that many homeowners enter boarding arrangements without fully understanding the tax implications. A common situation involves renting a spare room for extra income, then adding meals, which inadvertently shifts the arrangement into a different tax category with new rules for income and deductions.

What Boarding Income Means For Your Tax Return

From a tax perspective, "boarding" involves more than just renting out a room; it is defined by providing accommodation plus other domestic services. Unlike a standard tenant paying solely for space, a boarder pays for a package of services. This distinction is crucial for tax purposes as it directly affects how you report income and what expenses you can legitimately claim as deductions.

The fundamental rule is straightforward: if you receive money for providing these services, the ATO requires you to declare it. The benefit of this is that it also allows you to claim deductions for a portion of your household running costs, which can significantly reduce your overall tax liability.

Key Concepts To Understand

Before diving into the details, it's important to grasp a few key concepts the ATO uses when assessing boarding arrangements.

• Assessable Income: This includes every dollar received from your boarder. It covers payments for the room, food, utilities, and any other services provided as part of the agreement. All of it must be declared.

• Deductible Expenses: You can claim a portion of your home's running costs against the income earned. This can include expenses like electricity, internet, council rates, and even groceries.

• Apportionment: This is a critical calculation. You cannot claim 100% of your household bills. You must determine a reasonable percentage that relates directly to the boarder, typically based on factors like the floor area they use and the number of people living in the house.

• Capital Gains Tax (CGT): Using a part of your main residence to generate income can expose that portion of your property to CGT when you eventually sell. This is a significant future consideration that requires careful planning.

Properly managing these elements is essential for staying compliant with the ATO. If you operate this as a more formal business, you will also need to consider obligations like getting an ABN and keeping up with your tax compliance.

How The ATO Sees Your Boarding Activities

When assessing tax obligations, the Australian Taxation Office (ATO) looks beyond simple labels like 'boarder' or 'tenant' to understand the true nature of your arrangement. How your activities are classified is the first and most critical step in determining your tax responsibilities.

The core distinction often comes down to whether you are simply collecting rent or providing a more comprehensive service. Correctly classifying your arrangement from the outset dictates everything that follows, from the income you must declare to the deductions you are permitted to claim.

Hobby Versus Business: The Critical Distinction

A primary consideration is whether you are running a business or engaged in a domestic arrangement or hobby. This is not a matter of semantics; it fundamentally changes your obligations, including whether you need an ABN or must register for GST.

The ATO is likely to view your arrangement as a hobby or domestic setup if:

• It is a small-scale, private situation, such as renting a room to a friend.

• There is no clear intention to make a profit; for instance, charging a family member just enough to cover their share of expenses.

• The activity is irregular and lacks a formal, business-like structure.

Conversely, the ATO will probably classify your activities as a business if you:

• Have a clear intention to make a profit.

• Operate in a systematic, organised manner, similar to a commercial venture.

• Your activities are significant in size and scale, for example, hosting multiple boarders and actively advertising for new ones.

• Operate under a registered business name with formal agreements.

Imagine a homeowner in Sunnybank who begins by renting a spare room to a university student. This is likely a domestic arrangement. However, if they convert their granny flat, take on three more boarders, provide regular meals, and advertise the rooms online, their activities have almost certainly crossed into being a business. This shift means they would likely need an ABN and would be subject to a different set of tax rules.

Common Boarding Models And Their Tax Treatment

Your tax obligations will vary significantly depending on the type of boarding service you provide. Below, we break down common scenarios, from a casual housemate to a full-scale commercial operation.

This table compares the primary tax, GST, and ABN registration obligations for common boarding scenarios to help you identify your situation.

Boarding Type	Income Classification	ABN Required?	GST Registration Trigger	Primary Deductible Expenses
Private Boarding	Assessable Income	Generally No	Unlikely to meet threshold	Apportioned running & occupancy costs
Commercial Boarding House	Business Income	Yes	When turnover threshold is met	All ordinary business costs
Pet Boarding (Kennels)	Business Income	Yes	When turnover threshold is met	All ordinary business costs
NDIS/Foster Care	Varies (Often Non-Assessable)	Depends on arrangement	Depends on arrangement	Varies, often reimbursement

As illustrated, the requirements for someone renting out a spare room are vastly different from those for a registered boarding house. Understanding your classification is key.

Specialised Boarding Arrangements

Beyond typical room-and-board setups, certain arrangements have unique rules.

• Pet Boarding Facilities: Operating a kennel, cattery, or similar pet-minding service is considered a business by the ATO. All income is assessable, and you can claim deductions for all legitimate business expenses. Once your annual turnover reaches the GST threshold, you must register for and charge GST.

• NDIS and Foster Care: Payments for providing foster care or certain NDIS accommodation often have special rules. Payments from a state or territory agency to cover a foster child's expenses are typically considered reimbursements and are not taxable. However, these rules can be complex, so it is vital to confirm the nature of any payments with the issuing agency.

Correctly classifying your activities is fundamental. It dictates whether you need an ABN, if you must register for GST, and the full range of expenses you can claim. An error at this stage can lead to significant compliance issues with the ATO.

Managing ABN, GST And BAS For Your Boarding Business

Once the ATO classifies your boarding activities as a business, you enter a new framework of compliance. Understanding the Australian Business Number (ABN), Goods and Services Tax (GST), and Business Activity Statements (BAS) is non-negotiable for operating legally and avoiding penalties.

These systems are how the tax office monitors business income and ensures fair tax contribution. For a boarding operation, this means knowing precisely when to register for each and how to report your financial activity to the ATO.

Do You Need An Australian Business Number?

If your boarding operation is considered a business by the ATO, you are entitled to an ABN. This is your unique 11-digit identifier for all government and business interactions. While not always legally required from day one, operating a business without one can create significant challenges.

Here’s why an ABN is advisable:

• Avoiding PAYG Withholding: Without an ABN, other businesses paying you may be required to withhold tax from your invoices at the highest marginal rate, severely impacting your cash flow.

• Claiming GST Credits: You cannot register for GST without an ABN. Without GST registration, you cannot claim back the GST paid on your business purchases.

• Professionalism: An ABN signals to suppliers and clients that you are a legitimate and professional operation.

Understanding GST Registration Rules

The Goods and Services Tax (GST) is the 10% tax applied to most goods and services in Australia. For businesses, the most critical rule is the GST registration threshold.

You must register for GST if:

• Your business has a GST turnover (gross income before GST) of $75,000 or more per year.

• You are a non-profit organisation and your GST turnover is $150,000 or more per year.

• You provide taxi, limousine, or ride-sourcing services, which require registration from the start, regardless of turnover.

If your income is below the $75,000 threshold, you can register voluntarily. This allows you to claim GST credits on expenses but also obligates you to charge GST on your boarding fees and lodge regular activity statements.

Demystifying The Business Activity Statement

The Business Activity Statement (BAS) is your regular report to the ATO. If you are registered for GST, you must lodge a BAS, which summarises the GST you have collected versus the GST you have paid.

Most small businesses lodge their BAS quarterly. On the form, you report:

• Total sales (all income received from boarders)

• GST collected on those sales

• GST paid on business purchases (your GST credits)

The difference between the GST collected and the credits claimed determines whether you owe the ATO or are due a refund. Our guide on how to lodge a BAS correctly covers the process in detail.

Do not underestimate the importance of this. The ATO's data-matching capabilities are increasingly sophisticated. Maintaining clean, accurate records for your BAS is your best defence against an audit.

Brisbane Example: Pet Boarding BusinessSarah runs a small pet boarding kennel from her property in a quiet Brisbane suburb. Her annual turnover is $85,000, so she is required to be registered for GST.* In one quarter, she earns $21,250 in boarding fees. The GST component of this income is $1,931.82 ($21,250 / 11).* During the same period, she spends $5,500 (GST inclusive) on pet food, insurance, and advertising. She can claim a GST credit of $500 on these purchases ($5,500 / 11).* When lodging her BAS, she reports the $1,931.82 collected and claims the $500 credit. She will need to pay the difference, $1,431.82, to the ATO for that quarter.

Calculating Income And Claiming Allowable Deductions

Accurate financial records are the foundation of tax compliance for any boarding arrangement. Before determining what you can claim, you must have a clear, consistent system for tracking all income and expenditure. This involves knowing your assessable income and correctly identifying every allowable deduction.

Getting this right is crucial. It ensures you meet your ATO obligations without paying more tax than legally required. The tax office expects every dollar of income to be declared, but it also allows you to fairly reduce this income with legitimate, related expenses.

Defining Your Assessable Income

First, you must identify all income that needs to be declared. For a boarding setup, assessable income is more than just the weekly payment for the room. It is the total of all payments received from the boarder as part of your agreement.

This typically includes:

• Regular lodging payments: The core amount paid for room and board.

• Contributions to bills: Any money the boarder contributes for utilities like electricity, gas, or internet.

• Payments for extra services: Fees for meals, laundry, cleaning, or other services provided.

The rule is simple: if a boarder pays you for a service, the ATO considers it assessable income. Maintaining a detailed log of every payment—including date, amount, and purpose—is non-negotiable.

Understanding Allowable Deductions

This is where you can actively manage your tax position. The ATO allows you to claim a portion of household expenses directly related to the income earned from the boarder. These costs generally fall into two categories: occupancy expenses and running expenses.

Occupancy Expenses

These are the costs associated with owning or renting the property itself. As the boarder is not the sole beneficiary, you must apportion these costs fairly.

Common occupancy expenses include:

• A portion of mortgage interest or rent payments.

• Council rates and land tax.

• House and contents insurance premiums.

Running Expenses

These are the day-to-day costs of maintaining the household. Like occupancy costs, they must be apportioned fairly between you and your boarder for tax purposes.

Typical running expenses include:

• Electricity and gas bills.

• Water usage charges.

• Internet and phone costs.

• Costs for shared supplies like cleaning products.

• Food costs, but only if meals are included in the boarding fee.

You can often claim 100% of expenses solely for the boarder, such as advertising the room or repairing an item in their private space. For more detail, our guide on rental property deductions in Australia provides further information.

The Crucial Concept of Apportionment

You cannot claim an entire electricity bill just because you have a boarder; this is a direct route to an ATO audit. Apportionment is the method used to calculate the deductible portion of any shared household expense. While the ATO does not prescribe a single formula, your method must be reasonable and justifiable.

A common and defensible approach involves two steps:

1. Calculate the floor area percentage: Determine the percentage of your home’s floor area for the boarder’s exclusive use (their bedroom) and shared use (kitchen, lounge). This method is well-suited for occupancy costs.

2. Calculate on a per-person basis: For running costs like utilities and groceries, a simple per-person split is often the most reasonable method. If three people live in the house (e.g., you, your partner, and one boarder), you could reasonably claim one-third of these shared costs.

Here’s a simple text diagram to illustrate the process:

Total Household Bill (e.g., Electricity)
│
├── Your Private Area (Not Deductible)
│
├── Boarder's Private Area (Deductible Portion)
│
└── Shared Areas (e.g., Kitchen, Lounge)
    │
    ├── Your Share (Not Deductible)
    └── Boarder's Share (Deductible Portion)

Calculation Method: Apportion based on floor area for occupancy costs and per-person basis for running costs.

Brisbane Example: Apportioning ExpensesMark lives in a three-bedroom house in Brisbane and takes on a boarder. The boarder's room is 15% of the total floor space. Shared areas like the kitchen and living room comprise another 30%.For his $1,200 quarterly council rates (an occupancy expense), Mark calculates his claim as follows:* 15% (boarder's private room) + (30% / 2 people sharing) = 30%* His deduction is $1,200 x 30% = $360.For his $600 quarterly electricity bill (a running expense), he splits it per person:* $600 / 2 people = $300.The key for Mark is to keep meticulous records of the original bills and the logic behind his calculations.

Meeting Your Obligations For Staff And Contractors

As a boarding business grows, you may need additional help. Bringing on staff introduces a new layer of compliance with the ATO, particularly concerning payroll and superannuation. Correctly managing these obligations from the start is crucial to avoid future penalties.

The first and most critical step is to determine the nature of the working relationship: is the person an employee or a contractor? Misclassifying a worker is a common and costly error, as the tax and superannuation rules differ completely for each.

Employee or Contractor? The ATO’s View

The ATO does not rely on what you call the worker or what is written in an agreement. It assesses the entire working arrangement to determine the true relationship. Misclassifying an employee as a contractor, even unintentionally, can lead to significant liabilities, including back-payment of PAYG withholding and superannuation, plus interest and penalties.

The ATO considers several key factors:

• Control: How much authority do you have over how, where, and when the work is performed? An employee is typically directed, whereas a contractor has more autonomy.

• Tools and Equipment: Does the worker provide their own significant tools and equipment, or do you supply them? Contractors usually use their own assets.

• Risk: Does the worker bear any financial risk? A contractor operates their own business, meaning they bear the risk of making a profit or a loss and are responsible for rectifying defects at their own cost.

We explore this topic in greater detail in our guide on the differences between an employee and a contractor in Australia.

Obligations For Employees

If your worker is classified as an employee, you assume a specific set of responsibilities managed through the tax and superannuation systems.

Your main duties include:

• PAYG Withholding: You must withhold tax from your employee's salary and wages each pay period and remit it to the ATO. The amount withheld is based on their Tax file number declaration.

• Single Touch Payroll (STP): Each time you pay employees, you must report their payroll information—such as salaries, tax withheld, and superannuation—directly to the ATO using STP-enabled software.

• Superannuation Guarantee: You must pay superannuation contributions into your employee's nominated super fund, at a rate of at least the minimum super guarantee percentage of their ordinary time earnings.

Dealing With Contractors

Engaging a genuine independent contractor simplifies your obligations, but you are not entirely exempt from responsibilities. A contractor manages their own tax and superannuation.

Your primary responsibility is to:

• Check Their ABN: Before paying a contractor's invoice, you must verify they have a valid Australian Business Number (ABN).

• Withhold Tax If No ABN: If a contractor does not provide a valid ABN on their invoice, you are generally required to withhold tax from their payment at the top marginal rate and remit it to the ATO. This rule is designed to ensure tax compliance.

Brisbane Scenario: Hiring A CleanerA boarding house owner in Brisbane hires someone to clean the common areas for three hours every Friday. The owner provides all cleaning supplies, sets the exact hours, and gives a detailed task list. Even if the cleaner has their own ABN and calls themselves a contractor, the ATO would almost certainly classify them as an employee due to the high degree of control exercised by the owner. This means the owner is responsible for PAYG withholding and superannuation for this worker.

Managing payroll is a significant area of compliance. Lodgment statistics from the ATO show the complexity involved, with millions of Australians relying on professional help for areas like payroll and super.

Record Keeping To Avoid Common ATO Pitfalls

With the ATO, a proactive approach to compliance is always best. If you earn income from a boarding arrangement, robust record-keeping is not just good practice—it is your single most effective defence against an ATO audit.

Building good habits from day one will help you manage risk and stay prepared. Getting this right from the start can save significant time and stress, ensuring you can always justify your tax position with confidence.

Legally, the ATO requires you to keep records related to your tax affairs for at least five years after lodging your tax return. This involves more than just keeping receipts; it requires a clear, organised system that documents the complete financial story of your boarding activities.

Essential Records To Keep

Your record-keeping system must be meticulous, tracking every dollar in and every cent out.

Essential records include:

• Income Statements: A detailed log of all payments received from boarders, including dates, amounts, and what each payment covered.

• Expense Receipts: Original or digital copies of every deductible expense, from utility bills and council rates to grocery receipts and invoices for repairs.

• Bank Statements: A dedicated bank account for boarding income and expenses simplifies tracking and provides powerful supporting evidence.

• Apportionment Calculations: A clear worksheet showing exactly how you calculated the deductible percentage of shared household costs. You must be able to explain your methodology to the ATO.

Common Red Flags That Trigger ATO Audits

The ATO uses sophisticated data-matching technology to identify tax returns that deviate from the norm. For boarding income, certain claims are common red flags that can trigger a review or audit.

Avoid these common pitfalls:

• Claiming 100% of Household Expenses: This is one of the fastest ways to attract ATO attention. You can never claim the full amount of shared costs like mortgage interest or electricity; they must be apportioned.

• Failing to Declare All Income: All money received from a boarder is generally assessable income and must be reported. Overlooking cash payments is a compliance breach.

• Incorrectly Classifying Activities as a Hobby: If you have a regular, systematic arrangement designed to generate income, classifying it as a 'hobby' to avoid tax will not stand up to ATO scrutiny.

• Poor or Non-Existent Records: If audited, an inability to produce evidence for your claims will likely result in the ATO disallowing your deductions and issuing a revised tax assessment.

Understanding your tax obligations is vital. Declaring your boarding income correctly ensures you are paying tax at the appropriate marginal rate. For reference, you can learn about current and future tax brackets on SuperGuide. A solid grasp of the fundamentals of tax record keeping is essential for smooth tax compliance.

Summary

• Declare All Income: All money received from a boarder for accommodation and services is assessable income and must be reported to the ATO.

• Apportion Expenses: You can claim a portion of household running and occupancy costs, but you must use a reasonable apportionment method (e.g., based on floor area or per person).

• Hobby vs. Business: The scale and intent of your activities determine if you are running a business, which has different tax obligations, including potential ABN and GST registration.

• Keep Meticulous Records: Maintain detailed records of all income, expenses, and apportionment calculations for at least five years to substantiate your claims in case of an ATO audit.

• Understand CGT Implications: Using your main residence to produce income can trigger Capital Gains Tax (CGT) on a portion of the property when you sell it.

Frequently Asked Questions (FAQs)

Do I have to declare income from just one boarder?

Yes. Any money you receive for providing accommodation is considered assessable income by the ATO and must be included in your tax return, regardless of whether it's from one boarder or several. While the income is taxable, you can also claim deductions for the portion of your household expenses related to that boarder.

Are payments I receive for foster care taxable?

Generally, no. Payments from a state or territory agency for providing foster care are typically considered reimbursements to cover the child's expenses, not as taxable income. However, as programs can vary, it is advisable to confirm the tax treatment with the agency providing the funds.

What happens if I miss the GST registration threshold?

If your turnover from boarding services reaches the GST registration threshold and you fail to register, the ATO can backdate your registration to the date you were required to do so. You will then be liable for GST on all income earned from that date, potentially including penalties and interest for late lodgement and payment.

Can I claim my entire mortgage interest if I have a boarder?

No, you cannot claim 100% of your mortgage interest. This is an 'occupancy expense' and must be apportioned. You can only claim the portion of the interest that relates to the space the boarder uses (their private room plus their share of common areas) and only for the period they were paying you. Claiming the full amount is a major red flag for the ATO.
