Keeping business and personal finances separate is one of the most important fundamentals of bookkeeping. Nevertheless, in day-to-day life, situations may arise where a business purchase is paid for using a personal debit card, or a personal purchase is paid for using a business card. Using the wrong card in a rush is a human error, and a single incident does not usually cause any problems.<\/p>\n

However, if business and personal purchases are constantly mixed up, bookkeeping can easily become more laborious than it needs to be. At the same time, it becomes more difficult to monitor the company's financial situation.<\/p>\n

In this blog post, we explain why it\u2019s a good idea to keep your business finances separate from your personal finances, and how you can do so as easily as possible.<\/p>\n

1. Clear accounting saves time and money<\/b><\/p>\n

When a company's income and expenses are handled through their own account, bookkeeping is more straightforward. Each payment transaction can be processed quickly without additional reconciliation.<\/p>\n

If a bank statement contains both business purchases and personal purchases, the accountant must determine which transactions relate to the business and which do not. This often means additional questions and more time spent on bookkeeping.<\/p>\n

The clearer the records are, the more time your accountant can spend monitoring your company\u2019s finances and providing advice, rather than spending time sorting out individual payments.<\/p>\n

2. Taxation is also handled more easily<\/b><\/p>\n

A company's expenses must be related to the company's operations. If private purchases are accidentally processed as company expenses, they must be corrected in the accounting. Similarly, an acquisition belonging to the company should always be carefully documented, even if it was paid for with a personal card.<\/p>\n

When business and personal purchases are kept separate, the accounts and tax returns are also clearer. At the same time, you ensure that the deductions to which the business is entitled are claimed correctly.<\/p>\n

3. You can see better how your business is doing<\/b><\/p>\n

A company's bank account reveals a lot about its finances, but only when it shows the company's own income and expenses.<\/p>\n

If personal purchases are continually paid for from a company account, or company purchases are paid for from a personal account, the overall picture becomes blurred. In such cases, it can be difficult to assess, for example:<\/p>\n
