Starting a Side Business? Here's What You Need to Know

June 5, 2024

In today’s gig economy, starting a side business is a popular way to supplement income and explore entrepreneurial interests. Whether you’re freelancing, selling handmade crafts, or offering consulting services, a side business can be both rewarding and profitable. However, it also comes with certain responsibilities, especially when it comes to accounting and taxes. Here’s a comprehensive guide to help you navigate the accounting side of your new venture.


1. Keep Personal and Business Finances Separate

One of the first steps in setting up your side business is to separate your personal and business finances. This means opening a dedicated business bank account and possibly a business credit card. Keeping your finances separate helps you:

  • Track your business income and expenses more accurately.
  • Simplify your bookkeeping and tax filing process.
  • Build a financial history for your business, which can be useful if you seek funding in the future.


2. Track Your Income and Expenses

Accurate record-keeping is essential for any business. Here’s how you can effectively track your income and expenses:

  • Use Accounting Software: Invest in reliable accounting software to automate and streamline your bookkeeping. Popular options include QuickBooks, Xero, and Wave.
  • Save Receipts: Keep digital or physical copies of all business-related receipts. These are crucial for tax deductions and audit trails.
  • Document Everything: Record all income received and expenses incurred. Make it a habit to update your books regularly to avoid end-of-year stress.


3. Understand Your Deductions

Knowing what expenses you can deduct is key to reducing your taxable income. Common deductible expenses for side businesses include:

  • Home Office: If you use part of your home exclusively for business, you can deduct a portion of your rent/mortgage, utilities, and insurance.
  • Supplies and Equipment: Costs for business-related supplies, equipment, and software are deductible.
  • Travel and Meals: Business travel expenses and meals with clients can often be deducted, but make sure to keep detailed records.
  • Marketing and Advertising: Costs for promoting your business, including website expenses, advertising, and business cards, are deductible.


4. Set Aside Money for Taxes

Unlike regular employment, taxes are not automatically withheld from your side business income. It’s crucial to set aside a portion of your earnings to cover federal, state, and local taxes. Here’s how you can manage this:

  • Estimate Your Tax Liability: Use an online tax calculator or consult with an accountant to estimate your tax liability.
  • Quarterly Payments: If your side business is generating significant income, you may need to make estimated quarterly tax payments to avoid penalties.
  • Create a Tax Fund: Set up a separate savings account specifically for taxes and regularly transfer a percentage of your income into this account.


5. Consider Professional Help

As your side business grows, the complexity of your accounting and tax responsibilities will increase. It might be beneficial to seek professional help:

  • Hire an Accountant: An accountant can provide valuable advice, help you maximize deductions, and ensure your taxes are filed correctly.
  • Tax Preparation Services: Consider using a tax preparation service to handle your annual tax filings. This can save you time and reduce the risk of errors.



Starting a side business can be an exciting and profitable endeavor, but it requires careful attention to accounting and tax details. By keeping your finances organized, tracking your income and expenses, understanding your deductions, setting aside money for taxes, and seeking professional help when needed, you can ensure your side business remains financially healthy and compliant. Happy hustling!
