Save money and reduce errors by avoiding the top business expense tracking mistakes.
Tracking business expenses may seem simple, but it’s easy to make mistakes that can cost you tax deductions. In this blog, we’ll break down the most common errors small business owners make when tracking expenses — and how to fix them before they hurt your bottom line.
Keeping track of your expenses properly ensures that you never miss a valid tax deduction. Accurate tracking also provides clear insights into your business’s financial health, helping you make better decisions.
One of the most common errors is mixing personal and business expenses in the same account or card. This makes it difficult to track business expenses accurately and can cause problems during tax time.
Solution:
Keep separate bank accounts and credit cards for your business and personal expenses. This makes it easy to track and claim business expenses.
Many business owners neglect to store or organise receipts, making it impossible to back up expense claims. Without proper records, you may miss out on tax deductions or risk penalties for incorrect claims.
Solution:
Use apps like Expensify or Receipt Bank to keep all receipts and invoices stored digitally. This reduces the risk of losing important documents.
Some business owners lump all expenses together without categorising them. This leads to confusion and could result in missed deductions. For example, office supplies should be listed under office expenses, not miscellaneous.
Solution:
Create categories such as office supplies, travel, equipment, marketing, and more. Be consistent and review the categories regularly.
Subscriptions to software, memberships, and services are often overlooked because they’re recurring and easy to forget. These expenses can add up over time and should be properly accounted for.
Solution:
Set up automatic tracking for subscriptions through accounting software, so you don’t miss recurring expenses. Review your subscriptions quarterly to ensure everything is business-related.
If you’re only reviewing expenses at the end of the year, it’s easy to miss deductions. Waiting too long could also lead to mistakes in expense categories or missed claims.
Solution:
Set aside time weekly or monthly to review your expenses. This practice helps you catch mistakes early and ensures you’re on top of your claims.
Review expenses regularly: Check in with your accounting system weekly or monthly to avoid last-minute errors.
No, receipts are required to back up your claims. Use digital tools to store and manage receipts easily.
Create clear categories such as travel, office supplies, marketing, etc., and ensure you record every expense correctly in the right category.
Yes, you can claim a portion of your home expenses like rent, utilities, and internet bills if you work from home.
It’s best to check your expenses at least weekly to ensure everything is recorded accurately and consistently.
