Small business accounting: 5 common mistakes small businesses make

When starting out, many small businesses choose to take care of their own books. However, this can be the first of many mistakes, particularly if you have no experience in accounting. Here are some of the most common mistakes that you could fall victim to:

Mistake #1: Mathematical miscalculations

Armed with a calculator, you might think that nothing can go wrong when working out your earnings and outgoings. But it's all too easy to slip up and make mistakes, which can be difficult to spot if you're not used to working with numbers. Errors like this could cost your company in the long term, as you might not have the money to run certain operations, or tax time could hit you in a particularly bad way. It's always best to check figures several times or, even better, ask a professional to handle them for you.

Mistake #2: No backups

Too many small businesses forget to back up their financial records. Whether you're using professional software or not, it's important to have at least two copies of your books. This could be a paper and digital copy or linking your accounts to secure cloud storage. If you don't have any backups, you could quickly find yourself in hot water when your computer's hard drive fails and you have no information to give the taxman.

Mistake #3: Not setting a budget

It's essential to stick to a budget, not just so you know how much you can spend, but also to give you an idea of how your business is growing. Budgeting and forecasting can help you to plan your finances better and highlight areas where you need to cut costs or have room to spend a little extra.

Mistake #4: No separate business and personal accounts

When you use the same account for your personal finances as well as your business, things quickly become confusing. By keeping your finances separate, you'll always know what transactions were commercial and available to claim tax on, and which transactions were your own and unrelated to your business' budget.

Mistake #5: Trying to DIY on your bookkeeping

All of these common mistakes can be avoided by opting to choose a professional bookkeeping service. At Ascent Accountants we’ve been helping small businesses in Perth for many years now to stay organised and on top of their business’ tax, books and overall financials.

One of the most powerful decisions you can make with your superannuation is whether to run your own self-managed super fund (SMSF) and whether to invest in property through it. Most people know it's possible to use super to buy property. Far fewer know how to do it well. The following seven tips are designed to help you make the right decisions. 1. You Can Borrow Money to Purchase Property in Superannuation. Don't have enough in your SMSF to buy an investment property outright? Since 2008, superannuation held in a self-managed super fund can be used to borrow money for property purchase. This is done through a 'limited recourse loan' using a Bare Trust as the Custodian entity. You can't borrow the total value of the property—typically it's up to 80% for residential properties and 60% for commercial properties, with the required deposit held in the SMSF as security. The SMSF then makes the loan repayments, with rental income received by the fund and property expenses paid by the fund. Importantly, if there is a default on the loan, your other assets in the SMSF are generally protected from standard debt recovery and bankruptcy proceedings. The lender only has recourse to the property itself. Upon completion of the loan repayment, ownership of the property transfers legally to the SMSF. 2. Follow These 8 Steps to Set Up Your SMSF Setting up an SMSF properly can be a complex process. It’s best to set up an SMSF with the assistance of a qualified superannuation advisor, like us! We can assist with both the initial setup and the ongoing management of your fund. There are eight core steps to SMSF set up: Select the appropriate structure and name Sign the trust deed that covers how your SMSF is set up and run (it can have up to four members) Establish a trust for the SMSF by investing assets into the fund Register your SMSF with the ATO Set up a separate bank account for your fund Submit your tax file number (and those of any other trustees) Obtain an electronic service address to receive employer contributions into your fund (if applicable) Roll over funds from your existing superannuation account into your SMSF 3. Keep a Liquidity Buffer If you're buying property through superannuation, make sure you plan to keep a liquidity buffer of cash and/or shares in your fund. Lenders will check for this before lending to you—it should be at least 10% of the value you intend to borrow. But beyond satisfying the bank, it's simply good risk management. Property is an illiquid asset. Having accessible funds in the SMSF means you're not caught short if repairs are needed, the property sits vacant, or an unexpected expense arises. Because superannuation is central to most Australians' retirement security, the government has carefully regulated what can and can't be done with it. They don't want people gambling their retirement away on poor investments or incorrectly using their superannuation fund. 4. Use the Rental Income to Repay Your Loan You cannot live in the property you purchase through your SMSF until after retirement. Most people purchase an investment property and use the rental income generated to repay the loan—which makes excellent financial sense. The key is selecting a property that rents easily and delivers a strong rental return. Your purchasing criteria may look a little different to buying a home you'd live in yourself. For example, proximity to public transport, local amenities, and average rental rates in the area matter more than personal preference. 5. Get It Right and Enjoy Significant Tax Efficiencies One of the most compelling reasons to invest in property through superannuation is the tax efficiency on offer. These benefits can significantly improve the long-term return of a property investment compared to holding it in your own name. Key tax benefits include: No capital gains tax or tax no yearly investment earnings if under super caps. Salary sacrifice advantages if you're sacrificing salary payments into super, loan repayments are effectively tax deductible. Capped tax on investment income—the maximum rate of tax on income after expenses is 15%. Any capital gains on investments held for 12 months or more, is taxed at 10%. Standard investors outside super can pay up to 47%. 6. Follow the Same Due Diligence Rules as Any Property Purchase Buying through superannuation doesn't mean relaxing your standards. If anything, the rules governing SMSFs mean you need to be more rigorous, not less. Property is likely one of the most significant financial decisions of your life. Research, not emotion, should drive your choices. The same rules apply whether you're buying in or out of super: Visit and compare multiple properties Know the values of similar properties in the same area Get all property checks performed by the right professionals Shop around for the right loan structure and lender Don't abandon good investor habits just because the structure is different. 7. Always Get Quality Professional Advice Nothing comes without risk—but the right advice significantly mitigates it. The key is understanding what you're getting yourself into: making informed decisions based on accurate data; keeping a diversified superannuation portfolio that doesn't place all your eggs in one basket; and not underestimating how complex buying property in superannuation can be. Sound Simple? It’s all in the details. If the above tips have made it sound straightforward, know that the detail is where the complexity lives. Getting professional advice from the start helps ensure you make the best possible decisions for your future. When selected according to rigorous property-purchasing criteria, property can be an excellent way to grow your superannuation and increase your chances of building a retirement fund that supports the lifestyle you want.
