18 small business expense categories you need to know

Payroll is an important category to consider given the sizable amount of finances that are dedicated to it. This could include wages, bonuses, or commissions that you pay workers, whether they're full-time employees or contractors.

Any money that you pay to either rent, mortgage, or own any office space should be recorded separately in a dedicated category. Especially because it can be included in your list of tax-deductible business expenses.

With the rise of remote work in 2020, the worth of actual office spaces has gone down, particularly for SaaS startups and other knowledge-based companies. However, retailers don’t have much of a choice and must stick with listing rent as a recurring business expense.

Closely linked to rent, utilities could include your electricity, wi-fi, air conditioning, water, garbage, and recycling costs. These are closely related to the costs of running a physical office space and can all add up quite quickly.

As with rent or mortgage payments, utility bills can also be considered as tax-deductible business expenses. However, in some cases, utility costs are written into rent agreements and therefore cannot be considered a separate expense.

As the digital world goes even more digital, software subscriptions have become an expense as regular as paying for gas or rent. Everyone has them, even if it’s just Microsoft Office. Companies usually have multiple subscriptions at the same time. For SMEs or startups in particular these costs when added up could add up to a significant number.

Your marketing expenditure will include not just paying for marketing personnel, which will fall under payroll. You’re also bound to spend money on the usual marketing channels such as social media and search advertising, physical leaflets, stickers, billboards, radio, and television, plus agency and freelancer help. All of which can be quite expensive and add up to a significant amount.

Because the fact that marketing has a direct relationship with growth, your spending will determine how fast you grow. In some countries, such as Singapore, Advertising and marketing can also be considered tax-deductible expenses. So, monitoring a big budget and a large range of marketing expenses in a separate category makes sense.

Travel and entertainment expense is another business expense category that can be tax-deductible. These expenses might be of low value individually but can add up quite easily. For SMEs and startups, it is imperative to capitalize on the tax deductibility factor and ensure that they can earn as many savings as possible.



Depending on the business categories your company is involved in these expenses could include sales visits, conferences and networking events, or just traveling for purposes related to the business.

Again, depending on the business categories you are involved in, servers and website maintenance costs hit different businesses differently. Smaller companies with standard websites probably won’t have to worry about this much because general server costs are usually just a couple hundred dollars. 

However, for tech companies especially, servers play a major role in business. When you’re hosting tonnes of customer data, company information on clouds, etc. these costs can balloon. Thankfully, website and server expenses, including software-as-a-service (SaaS), platform-as-a-service (PaaS), and infrastructure-as-a-service (IaaS) expenses, are also tax-deductible in countries like Singapore.

While we don’t usually think of tax as a separate expense (because it’s not exactly optional), it is still a candidate to be included in your list of business expense categories.

In most countries business expenses are tax-free. Keeping a close eye on your expenses and the amount of tax you’re paying, and making sure employees submit receipts and claim expenses on time, can go a long way in saving your business some serious money.

Like taxes, business insurance is not exactly an optional expense and can be quite expensive. Apart from mandatory government insurance schemes, there are also coverages for things like employment practices to product liability.

How much risk you are willing to take will determine which of these you will go for, and how likely you are to need them, of course. But at the very least, categorizing them separately can save you a lot of admin work.

Outsourcing non-essential parts of your business to experts or consultants can be a big boost, especially for SMEs and startups. There are professional services that even larger corporations choose to outsource simply because it is more efficient than having to keep people in-house. Advertising and PR agencies, for example, are often kept by big companies full time.

Expert advice does obviously come at a fair cost and can be a recurring one as well. So, it makes sense to list it as a separate business expense category.

This is a category that has existed for quite some time in big companies and is now gaining traction in the startup world as well. Training is a particularly effective method of ensuring uniformity of service, especially for companies that have branches in different parts of the world.



The quality of your training program will determine how well your employees perform and how consistent your service is. It’s clearly an important part of business expenses and should be a part of a small business expenses list as well.

At first glance, you’d probably expect equipment and furniture to be a part of office supplies. Yet, there is a distinction between the two. The equipment and/or furniture you buy for your business is more permanent than office supplies. This includes chairs and sofas, computers, television screens, fridges and storage units, printers and scanners, and other obvious office furniture.

Moreover, these objects and items, after a point in time, are also classified as business assets and can be used to generate income, through programs like asset-based or inventory financing. Their resale value is another factor that can add value to your business.

A smaller expense than most of the others already mentioned, office supplies are one of the more common forms of expenditure you can add to your list of business expense categories.

Off of the top of our heads, the first few things that come to mind when thinking of office supplies include things like stationery, hygiene products, coffee, etc.

But it could also include bigger purchases when you buy these same things in bulk. The problem with such purchases, however, is that they can be hard to track given that they are usually not made in any structured order. A good option to consider to combat this could be virtual cards that track expenses.

A few years ago home office setups might have been an employee’s personal responsibility; but, like so many other things, this too has faced the impact of Covid-29. With almost half the world working from home, home office setups have become increasingly important and are climbing higher on the list of business expenses.

When employees travel by car for work, not to work, their fuel costs are usually reimbursed. Moreover, employees using their own car for work can claim a mileage allowance, a cost set owed due to the wear and tear the car is to face. These expenses are universally treated as a separate expense category because of their tax-saving attributes.

Everybody loves appreciation and so do employees. Smaller perks such as snacks and drinks, t-shirts and hoodies, team-building activities and retreats, and stickers can easily put a smile on anyone’s face, including your employees. Letting them know your appreciation towards their hard work is only going to boost morale and indirectly benefit the company itself.

There are also bigger perks such as health insurance, paid time off, maternal leave, etc. These could be wrapped up in both payroll and business insurance, but you could provide specific perks and benefits that don’t fit those categories.

It’s also a wise move to include the costs of any occupational licenses, health permits, and other required certifications that you or your business has had to acquire. Getting licenses and permits can be quite expensive depending on your industry and ought to be logged as a separate business expense category.

Any borrowed funds or ongoing credit lines that your company has will obviously come with interests or some form of bank fees. If you have to pay for things like minimum balance fees or overdraft fees, ensure you record those, too.
