Business credit cards offer the ease of managing business expenses efficiently and effectively. A business credit card is an excellent tool for tracking business expenditures. These expenses may be eligible for tax deductions. A tax deduction is an expense that can be subtracted from a business's revenue to calculate its net profit. This reduces the overall profit on which tax is calculated, thereby lowering your tax liability. The credit card statement provides a convenient record of potential deductions, but the eligibility of each expense is determined solely by the rules set by the Canada Revenue Agency (CRA).
Now, let's explore the prerequisites for applying for tax deductions and the types of expenses that are tax-deductible. We offer a comprehensive guide to business credit cards and their associated tax deductions.
If you are not familiar with the concept of tax deduction, let me explain it in simple terms for you. Tax deduction refers to the reduction in the amount of tax you owe to the state or government. It is the deduction of business-related expenses from a company's revenue, which means that the company's tax liability will be lower as its profits are now lower.
Claiming a business expense as a tax deduction in Canada is a formal process governed by the Income Tax Act. The Canada Revenue Agency (CRA) oversees these regulations, and as the taxpayer, you are responsible for maintaining complete records to justify each deduction. While your business credit card statement is an excellent tool for tracking expenditures, it is important to remember that it is simply a record. The eligibility of any expense depends entirely on its compliance with CRA guidelines.
To ascertain whether transactions are conducted for business activities, there are some criteria that you have to meet. This criterion will help you understand the prerequisites to determine that the expenses you have incurred are directly related to business activities and have helped you fulfill the needs of your business. Here is the general criterion that you need to achieve to enjoy the perks of tax deduction.
Every expense you claim must be able to pass three fundamental tests required by the CRA. If an expense fails any one of these tests, it is not deductible.
1. The Business Purpose Test
This is the most important test. You must be able to prove that the expense was made with the clear intention of generating revenue for your business. The business itself must be a commercial activity with a reasonable expectation of profit. Personal expenses, even if paid with a business credit card, are never deductible.
2. The Reasonableness Test
The amount of the expense must be reasonable in the circumstances. The CRA has the power to deny the full amount of a claim if it is deemed excessive or extravagant. For example, booking a luxury presidential suite for a routine solo business trip would likely be considered unreasonable, and the CRA could limit your deduction to the cost of a standard room.
3. The Proof Test (Record-Keeping)
The burden of proof is always on you, the taxpayer. You must have complete, organized records to support every expense you claim. This means keeping all original source documents, such as itemized receipts and invoices, in addition to your credit card statements. These records must be kept for a minimum of six years after the end of the last tax year they relate to, as the CRA can request them at any time within that period.
It is imperative to maintain a strict separation between your business and personal finances. Using a single credit card for both types of transactions creates significant administrative challenges and can raise red flags for the CRA.
When business and personal expenses are mixed on one card, you are responsible for meticulously separating them and proving the business nature of each claim. Furthermore, you cannot deduct the entire annual fee of the card. You must pro-rate the cost based on the percentage of business use, a calculation that can be difficult to substantiate during an audit.
Using a dedicated business credit card is the most effective solution. It isolates all your business transactions, simplifies your bookkeeping, and makes justifying your expenses to the CRA a much more straightforward process.
To be tax-deductible in Canada, an expense must be reasonable and directly related to earning business income. Here are some common examples of what you can and cannot deduct.
In Canadian tax law, the costs associated with borrowing money for the purpose of earning business income are generally deductible. This principle extends directly to business credit cards, where various fees and interest charges are considered a legitimate cost of doing business.
When using a credit card for your business, the following related costs are typically deductible:
In essence, if a fee or charge is a direct consequence of using credit to finance your day-to-day business operations, it qualifies as a deductible expense against your business income.
No. According to the article, your credit card statement is simply a record for tracking. You must keep original source documents, like itemized receipts and invoices, as proof for the Canada Revenue Agency (CRA).
Using one credit card for both personal and business costs creates significant bookkeeping challenges and can raise red flags for the CRA. You also cannot deduct the full annual fee of the card; you must pro-rate it based on the percentage of business use, which can be difficult to prove.
You can only deduct a portion of your household expenses if your home office is your main place of business, or if you use the space exclusively and regularly to meet clients. The deductible amount is based on the size of your workspace.
