When Are Sales Tax Due? Filing Frequencies & Deadlines

Sales tax is a consumption tax businesses collect from customers on taxable goods and services, then remit to state and local governments. Timely remittance is crucial for compliance and to avoid penalties and interest.

Factors Influencing Sales Tax Due Dates

Sales tax due dates vary significantly, shaped by several factors. A primary determinant is the specific jurisdiction where a business operates and has sales tax nexus. Rules and due dates vary among states, counties, and cities. Businesses must adhere to regulations in every jurisdiction where they have a presence or meet economic nexus thresholds.

The volume of taxable sales or total sales tax collected often dictates filing frequency. Businesses with higher sales volumes typically face more frequent filing requirements. Conversely, businesses with lower sales volumes may be assigned less frequent schedules, such as quarterly or annually.

Less common factors can also influence reporting schedules. For instance, seasonal businesses or those in specific industries might have unique arrangements with tax authorities, impacting their due dates.

Common Sales Tax Filing Frequencies

Businesses typically follow one of three main schedules for remitting sales tax: monthly, quarterly, or annually. Monthly filing is often the most common frequency, particularly for businesses with higher sales volumes. Taxes collected in one month are generally due by a specific date in the subsequent month, often the 20th or the last day.

Quarterly filing is a common schedule for businesses with moderate sales tax liabilities. The standard quarters typically run from January-March, April-June, July-September, and October-December. Due dates for quarterly filers are commonly set for the end of the month following the close of the quarter, such as April 30th for the first quarter.

Annual filing is usually reserved for businesses with very low sales tax liabilities or specific small or seasonal businesses. Sales tax is often due once a year, frequently in January of the following year. While these three are the most prevalent, some jurisdictions may have semi-annual or other less common frequencies.

Locating and Fulfilling Your Specific Deadlines

To determine precise sales tax due dates, businesses should first consult their state’s Department of Revenue or equivalent tax agency website. These official sources typically provide detailed tax calendars and specific guidance. Businesses also receive their assigned filing frequency and due dates upon sales tax registration with the state. Setting up an account on the state’s online tax portal can offer personalized information and reminders.

Once the sales tax return is prepared, businesses can file and pay through several common methods. Most jurisdictions offer online portals for electronic filing and electronic funds transfer (EFT), which are often mandatory for businesses exceeding certain tax remittance thresholds. Mail-in forms are sometimes an option, though electronic methods are generally encouraged for efficiency and to avoid potential delays. It is important to file a sales tax return for every period, even if no sales occurred and no tax was collected, to maintain compliance.

Failing to meet sales tax due dates can result in significant consequences, including penalties and interest charges. Penalties vary by jurisdiction but commonly include a percentage of the unpaid tax amount, often ranging from 5% to 10% per month or fraction thereof, with potential minimums or maximums. Interest also accrues on underpayments and late payments, further increasing the financial burden. While some states may offer extensions for filing a sales tax return, these extensions typically do not extend the payment due date, meaning interest may still accrue on any unpaid tax.
