Bookkeeping and Tracking Sales Tax: A Guide for Small Business Owners
One of the key components of bookkeeping is tracking sales tax, which can be complex and varies by location, type of product, and other factors. In this article, we will explore why sales tax tracking is crucial for businesses and how to manage it efficiently. Proper bookkeeping is essential for running a successful business, as it helps owners stay on top of finances, understand the business’s financial health, and make informed decisions.
Why Sales Tax Matters
Sales tax is a percentage based off the sale price of goods or services that businesses collect on behalf of the government. The amount businesses collect is not theirs to keep; rather, it is passed along to the appropriate tax authorities. Different states, counties, and municipalities may impose their own sales taxes, and they often vary by the type of product or service being sold.
The primary reasons tracking sales tax is important include:
Compliance with the law: Failure to collect or remit the correct amount of sales tax can lead to fines, penalties, and legal troubles.
Accurate financial reporting: Sales tax should not be counted as income, so accurate reporting is necessary to ensure that the business’s financial records reflect true revenue. You don’t want to pay more taxes than required.
Customer trust: Ensuring that customers are charged the correct sales tax amount helps build trust, as they can be confident the business is following regulations.
The Complexity of Sales Tax
Sales tax is not a one-size-fits-all obligation. There are many factors that influence the amount a business needs to collect:
State and local rates: Each state, and in some cases each city or county, may have its own rate. More information can be found on line or calling your city and state. Knowledge is powerful and lifesaving.

Product or service type: Some products, such as groceries or medicine, may be exempt from sales tax in certain jurisdictions, while others may be subject to a reduced rate.
Nexus: Businesses must collect sales tax if they have a "nexus" in a state, which means a significant presence, such as an office, warehouse, or employees in that state. A 2018 Supreme Court decision, South Dakota v. Wayfair, also made it easier for states to require businesses to collect sales tax on online sales, even if the business doesn't have a physical presence in the state. Typically an issue when selling online.
Exemptions: Some businesses and transactions may be exempt from sales tax, such as sales to nonprofit organizations or sales for resale. Tracking these exemptions is crucial to avoid overcharging customers.
Best Practices for Bookkeeping and Tracking Sales Tax
Tracking sales tax properly requires a combination of planning, the right tools (bookkeeping software like TW365), and attention to detail. Here are some tips for managing sales tax in your business:
1. Understand Your Sales Tax Obligations
Start by researching the sales tax laws in the states where your business operates. If you have a physical presence in one or multiple locations or make sales to customers in multiple states, be sure to check each state's sales tax rules. Tax rates, exemptions, and requirements can differ significantly. There are many credit card merchants that offer this within their services.
2. Use Bookkeeping Software
Modern bookkeeping/accountant software can automatically calculate and track sales tax based on your location, product type, and other factors. Software like TW365, QuickBooks, Xero, or Avalara simplifies sales tax management by:
Automatically applying the correct sales tax rate based on the customer’s location.
Offering reports that show how much tax was collected and how much needs to be remitted to tax authorities.
Allowing you to set up tax-exempt customers, such as nonprofits, so they’re not incorrectly charged.
3. Maintain Detailed Records
It's essential to keep detailed records of every sale and the corresponding sales tax collected. This should include:
Sales receipts or invoices with the sales tax amount clearly displayed.
Information about the product or service sold, as some may be exempt or taxed at a different rate.
The location of the customer to ensure the correct sales tax rate is applied.
4. Separate Sales Tax from Revenue
In your bookeeping/accounting system, ensure that sales tax is tracked as a liability, not revenue, TW365 is preset this way for ease. While it may be collected with the sale, it does not contribute to your profits. Keeping it separate will help you calculate your true earnings and simplify tax filings.
5. File Sales Tax Returns on Time
Most states require businesses to file periodic sales tax returns, either monthly, quarterly, or annually. These returns report how much sales tax you collected and how much you owe the state. If you fail to file your returns or remit the tax on time, you may incur penalties or interest charges.
Use your bookkeeping/accounting software to generate the necessary reports showing your sales revenue and sales tax collected seperately to file your returns accurately and on time. Be sure to double-check for any changes in tax rates or rules that may affect your business.

6. Stay Updated
Sales tax laws can change frequently. New legislation may alter tax rates, exemptions, or reporting requirements. If you created your accounts with your state government, as required, they have great resources and many will send emails keeping upraised of updates and changes. Stay informed by subscribing to newsletters or using services that alert you to changes in sales tax laws in the states where you do business. This will help you remain compliant and avoid mistakes.
7. Consult with a Tax Professional
If you are unsure about how to handle sales tax for your business, it’s worth consulting with a tax professional or an accountant. They can guide you on proper sales tax collection, exemptions, and filing requirements, particularly if your business operates across state lines or deals with complex tax situations. Many times once setup you may not need their services again.
The Consequences of Poor Sales Tax Management
Failing to properly track and remit sales tax can result in several negative consequences:
Penalties and interest: States can impose significant penalties for late payments or incorrect reporting.
Audit risk: Inconsistent sales tax reporting increases the likelihood of an audit by tax authorities, which can be time-consuming and costly.
Reputation damage: Overcharging, undercharging and not collecting/charging customers can lead to dissatisfaction and harm your business’s reputation.
Conclusion
Sales tax can be complicated, but with the right bookkeeping practices in place, you can stay compliant and avoid costly mistakes. Understanding your sales tax obligations, using accounting software, keeping detailed records, and filing returns on time are essential steps in managing sales tax.
