50 Best Side Hustles for Accountants

Congrats for already being such a well-respected professional. People assume you are smart, detailed, and reliable. Take a look at these side hustles for accountants, which often involve solo work for someone with an accountant’s specific skills.

Here are the 50 best side hustles that let you set your own hours and make money in your free time.

1. Virtual Fractional Bookkeeping

You will be able to scale more easily by keeping your work online (or virtual) to save on time commuting. The idea behind “fractional” work is that your client is purchasing the amount of bookkeeping services they need from you, instead of having a full-time bookkeeper.

Getting Started: Update your resume to emphasize your bookkeeping experience. Look for customers in need of virtual bookkeeping services on Upwork, Craigslist, and Indeed. Create professional profiles on online platforms to convey your expertise. Also use traditional networking methods to market your skills.

Potential Earnings: The average rate for a virtual bookkeeper is about $19 per hour.

Other Helpful Information: If you perform well and build a trust with your client base, you can offer to expand the scope of services for those clients into higher-paying work such as accounting and tax services.

2. Virtual Fractional Accounting

Getting Started: Similar to virtual fractional bookkeeping, you would update your resume and contact prospects through various methods. While your bookkeeping services focus on keeping a company’s financial data recorded and organized, your accounting services would gather data for presentation to the company’s owners and investors.

Potential Earnings: The average rate for a virtual bookkeeper is about $24 per hour.

Other Helpful Information: As with most situations, if you impress your client with your work and build rapport, you could offer additional services. In the case of accounting services, if you have exposure to the company’s investors, you could let them know about your services as well. As you acquire more clients, you will want to think about building out your team under you.

3. Virtual Fractional CFO Services

Getting Started: Being a Chief Financial Officer for a company is a big responsibility and highly respected position. As an accountant, you are well-positioned for this role. Use virtual fractional accounting jobs (above) as a springboard to offering the more extensive CFO clients to small companies that cannot afford a full-time CFO. Then, get that experience on your resume to leverage it for more fractional CFO clientele.

Potential Earnings: Depending on the size of the company, full-time CFO’s make in excess of $200K. Build out your portfolio of other clients where you are a fractional CFO, and you will be able to charge premium rates.

Other Helpful Information: The CFO position is one of the most important in the company. It has access to sensitive financial information and lets the C-suite know the financial pulse of the company.

A good place to strart is by networking in person in your community and in local small business groups. Until you have fractional CFO experience, meeting potential clients in person (even though the work you will do for them will be from your own home or office) will help establish trust.

The more companies (with websites) that you have as clients, the more trusting your portfolio will be in getting new clients that are outside your local area. The reason why you want your clients to have websites is because that makes them seem like established companies to your prospective clients.

4. ​​eBook Writing on Accounting and Tax Topics

Getting Started: Choose a topic you can write an eBook about based on your professional expertise. Create an outline for your eBook. Write the book yourself or hire a freelancer through Upwork or Fiverr. Research eBook publishing platforms such as Kindle Direct Publishing. Publish and market your eBook.

Potential Earnings: Some eBook writers earn six figures. You may be more likely to earn a few extra hundred dollars a month.

Other Helpful Information: You can promote your eBook on your blog or through other such channels to attract more customers.

5. Business Plan Consulting

Getting Started: Create a website promoting your ability to write and review the financial aspects of business plans for local business owners. Ask your current clients if they need this service or if they can refer you to other clients.

Potential Earnings: You may charge about $2,000 to write or review a basic business plan.

Other Helpful Information: Don’t make any guarantees to your clients. Simply explain how your experience as an accountant or bookkeeper allows you to professionally review the financial plans of new small business owners.

6. Online Teaching (Accounting & Tax)

Getting Started: Read books and guides on creating online courses. Write and create your online accounting course. Choose a platform on which to publish your online course, such as Teachable, Thinkific, and Podia.

Potential Earnings: A successful online course that attracts regular customers could earn between $1,000 to $10,000 every month.

Other Helpful Information: To boost your earnings, you may want to take an online course that specifically teaches you how to market an online course you have created.

7. CPA Exam Tutoring

Getting Started: Pass the CPA exam. Check the jobs pages of CPA tutoring services for openings. Or, promote your services directly to customers via platforms like Craigslist.

Potential Earnings: For a specialized tutoring service like CPA exam tutoring, you may charge an average of $70 per hour.

Other Helpful Information: Because the CPA exam may be updated over time, make sure you learn about these updates. This is key to offering truly valuable help to your customers.

8. Accounting Tutoring

Getting Started: Consider earning a tutoring certification from a local college or an institution like the National Tutoring Association. Look into tutoring services with job openings or create a website to market your own private tutor services directly to customers.

Just like with the CPA Exam tutoring, Outschool is a great platform where you can have classess listed on Outschool’s directory and Zoom your tutoring individually or in groups all over the world.

Potential Earnings: The average rate for tutoring services is $55 per hour, but check the competition on the platforms you choose and price accordingly.

Buy a camera, tripod, and video editing software (such as Adobe Premiere Pro). Plan, write, and record at least your first three episodes. Start your channel, publish your episodes, and market the channel. Choose ways to monetize your channel, such as ad revenue, sales, donations, and sponsorships.

Options include local stores, local events, and online platforms like Etsy.

You may also sell them online through platforms like Craigslist and Facebook Marketplace.

Potential Earnings: This is a good way to earn a few extra dollars at one time. Unless you have many items to get rid of, it’s not a way to consistently earn passive income.

Other Helpful Information: Advertise the items you are selling through your social media accounts and other such platforms to find customers.

32. House Sitting
