9 ways for small business owners to keep the taxman happy

When Benjamin Franklin said that the only things certain in life were “death and taxes” most people didn’t consider that they may be closely linked.
But problems with taxes can lead to the death of your small business unless you take steps to keep the taxman off your back.
With sales meetings, recruitment, salaries, cashflow issues, marketing, suppliers, and a whole string of other things for small business owners to worry about, there’s no need to add the taxman to the list.
A robust financial system that keeps the tax authorities happy should be the foundation that underpins your business - allowing you to focus on the multitude of other issues that require your attention.
The specific requirements set out by your tax authority will differ by location but many of the basics remain the same wherever you are.
And most authorities are currently tightening the rules and clamping down on tax cheats and tax avoidance.
Nine of the most important general guidelines are detailed below: wherever you’re located, whatever your business size, and whatever industry you’re in, these will help you identify red flags in your tax setup:
1. Understand all the tax requirements - or find someone who does
Do you think your tax affairs are simple? They’re probably not. Ninety-nine percent of small business owners don’t fully understand tax legislation - so it’s important to seek specialist help.
The temptation a business owner is to try to look after everything yourself. With tax, this can be a false economy: not only can it take ages to get to grips with what you need to do; it’s likely that you’ll miss something important. And the taxman will be on your back!
2. File returns on time
The general rule is to file tax returns within twelve months of the end of your accounting period but this may vary with location.
Good planning in your business will ensure that you’re ready for the process; you know when it’s coming, have scheduled time to do it each year, and don’t end up scrambling around at the last minute to avoid penalties.
3. Keep consistent & accurate records
You should already understand the importance of accuracy and consistency: quite apart from generating the management reports to make good business decisions, the tax authorities love you for it too.
Being consistent and accurate will help you flag any changes that affect your tax liability and explain any changes that raise questions from the tax authorities.
If you have some bookkeeping experience, you may be able to manage this yourself with user-friendly cloud software like Xero and Quickbooks Online. Otherwise, it’s best to have a certified bookkeeper or accountant keep your accounting records up to date.
4. Keep the ‘evidence’ together
Keep the receipts and invoices for business expenses together. Most business owners know they should do this but it’s surprising how many find themselves scrambling around looking for receipts when the time comes to do tax returns.
And even when they do find the receipts, they don’t know what they relate to.
Keep it organised. All tax authorities want to know that there is sufficient documentation to justify business expenses. Receipts don’t have legs. Your own inefficient system is responsible for losing them or causing confusion about their origin.
One of the benefits of using a cloud computing app such as Xero is the ability to take a photo of a receipt with your smartphone to ‘scan in’ an expense receipt straight into Xero; or you can use specialist apps that integrate with Xero such as Receipt Bank or Expensify.
5. File business & personal expenditure separately
It’s easy to confuse business and personal expenditure. Unfortunately, it’s one of the quickest ways to get offside with the tax authorities.
By keeping them separate, you can see at a glance what you can deduct and what you can't: that means two separate (probably electronic) filing systems. Don’t be tempted to think “I’ll sort them out when the time comes for my tax return”. You’ll forget or cause delays.
6. If you’re a cash-based business, take extra steps
For small business owners such as tradespeople, who often get paid in cash, take extra steps to keep things transparent. You can guarantee that you will be on the taxman’s radar at some point.
For income, keep additional records to back up bank deposit records, such as cash register printouts or manual records of daily sales that can be matched to the bank records.
One of the benefits of moving your accounting systems to the cloud, is the ability to do things faster and easier with paperless processes. For example, trades-based businesses can use apps like ServiceM8 to quote and invoice in the field and even take electronic payments on site.
If you’re thinking, “I prefer to be paid in cash,” the ‘cash economy’—where a business does not declare all its income in order to reduce profits and therefore tax—is not such a great idea. Your business will be more valuable when it comes time to sell it if you have always shown all your sales revenue ‘on the books’.
7. Create a clear policy for employee reimbursement
Tax auditors want to know that you’re following the regulations with regards to employee reimbursement for travel, mileage, personal expenses, etc. They also want to know that expenses are appropriately signed off within the business to indicate that the business accepts liability.
Document a clear policy that determines what employees can claim for and how they go about claiming it. Make sure that this is clearly communicated to all employees.
8. Plan for your tax bill
There’s no room for surprise tax bills on the path to success. Tax is generally predictable and consistent. This means that you can - and should - plan for it in advance.
Sit down with your tax professional, understand what’s coming and when, and create a fund that can be used to pay the bill when it arrives. Maybe lock away a set sum every month. That way there are no nasty surprises ahead.
9. Never avoid the letters
Just because your tax authority writes to you asking questions or requesting records, it doesn’t necessarily mean the worst. Never avoid or delay answering these questions, as they don’t go away.
Answer in a timely fashion - there will normally be an expected response date detailed on the letter. Don’t go beyond this.
Take some tax advice and answer the questions to the best of your abilities. Most tax issues can be solved relatively easily if they are dealt with before they spiral out of hand.
Don’t get caught out by non-compliance with tax or it can cost you and your business. Get the right tax advice from the start and follow the tips above to keep the taxman happy.

If your business provides a car to an employee (or you’re the business owner/employee using it), there’s a good chance the Fringe Benefits Tax (FBT) rules apply. A car fringe benefit arises when a car owned or leased by an employer is made available for the private use of the business owner, an employee or their associate (such as a family member). “Private use” doesn’t just mean weekend road trips — it can include everyday commuting and even cases where the car is parked at an employee’s home, making it available for personal trips. Understanding how FBT is calculated and what records to keep is essential for compliance — and for avoiding paying more tax than necessary. What counts as a “car” for FBT purposes? The FBT law defines a car as a motor vehicle (except a motorcycle or similar) designed to carry less than one tonne and fewer than nine passengers. From 1 July 2022, some zero or low-emission vehicles are exempt from FBT, provided they meet certain criteria — for example, they must be first held and used after 1 July 2022 and must not have attracted Luxury Car Tax. Electric vehicle running costs, such as charging, are also exempt when the vehicle itself qualifies. Two main methods for calculating FBT on cars There are two ways to calculate the taxable value of a car fringe benefit. 1. Statutory formula method This method applies a flat 20% statutory rate to the base value of the car, adjusted for the number of days in the FBT year the car was available for private use. The formula is: (A × B × C ÷ D) − E A = Base value of the car (cost price plus GST and certain accessories, less registration, stamp duty and eligible reductions) B = Statutory fraction (generally 20%) C = Days available for private use D = Total days in FBT year (365) E = Employee contributions If the car has been owned for at least four full FBT years, the base value can be reduced by one-third. 2. Operating cost method This method calculates the taxable value by applying the private use percentage to the total operating costs of the car (actual and deemed costs). The formula is: Taxable value = [Operating costs × (100% − Business use %)] − Employee contributions Operating costs include: Fuel, oil, repairs, maintenance, registration and insurance Lease costs (for leased cars) Deemed depreciation (25% diminishing value) and deemed interest for owned cars Certain costs, such as tolls, car parking and insurance-funded repairs, are excluded. The business use percentage is determined by odometer readings, logbook records, and a reasonable estimate based on usage patterns. The three-month logbook requirement (operating cost method only). If you use the operating cost method, you must keep a logbook for at least 12 continuous weeks (roughly three months) to record: The date of each trip Odometer readings at the start and end Total kilometres travelled Whether the trip was for business or private purposes The purpose of each business trip This logbook is generally valid for five years, but you must start a new one if usage patterns change significantly (e.g., a role change, relocation or different duties). You also need to record odometer readings at the start and end of each FBT year. Why record-keeping matters. Keeping accurate records can support a higher business use percentage (and therefore a lower FBT bill). They also ensure you claim only legitimate business kilometres and help you provide evidence if the ATO reviews your FBT calculation. Finally, your records help you decide which calculation method (statutory or operating cost) is more tax-effective. Key takeaways for businesses and employees. If a car is available for private use, FBT may apply — even if the car isn’t driven often for personal trips. Electric cars may be FBT-exempt if they meet eligibility criteria, but you may still need to calculate their taxable value for reporting purposes. The operating cost method often works better if business use is high — but only if you have a compliant logbook. Keep odometer readings, expense records and a valid logbook to support your claims.
