Sales Tax Filing Frequency Changes & How to Manage Them

If you know anything about sales tax, you know that it’s always changing. One way states like to keep you on your toes? By changing your assigned filing frequency based on your sales and tax liability.

These changes often roll out right before the start of a new year (November-December) and again mid-year (May-June) after states process prior-period filings and audit reviews.

But between holiday chaos and year-end close, these filing frequency changes can be easy to miss.

This article covers:

• Why states change filing frequencies (with example)
• How states notify businesses
• How you can request a filing frequency change yourself
• A beginning-of-year checklist to stay ahead of compliance surprises

How Are Sales Tax Filing Frequencies Assigned?

Once your business crosses a state’s physical or economic nexus threshold, your next step is registering for a sales tax permit. When you register, the state assigns your filing frequency—how often you must file and remit sales tax—based on two key factors: your sales volume and expected liability.

Higher sales equal more tax collected, which will lead to more frequent returns.

After you’ve been registered and filing for a while (typically at least 12 months), states may re-evaluate your assigned frequency. These reviews typically consider:

• Historical sales or tax liability over the past 12 months
• Compliance history, including late filings or non-filings

Common sales tax filing frequencies

While there are outliers, most states assign one of three potential filing frequencies:

1. Monthly – common for sellers with high volume and high tax liability
2. Quarterly – for mid-range sellers
3. Semiannual or Annual – for low-liability or seasonal sellers

States periodically re-run liability reports, especially toward the end of the calendar or fiscal year. It is important to remember that your assigned filing frequency is not permanent. Expect changes if your sales spike, drop, or stay inactive for long periods.

Common Ways States Notify You of a Frequency Change

States communicate filing frequency changes in several ways, so you’ll want to keep an eye on:

Email notices

Some states now rely on email notifications, especially if you’ve opted in to paperless communication. Confirm your email address is current, or you may risk missing important updates.

Physical letters

Traditional paper notices are still used by many states. Ensure that the business address on your sales tax permit is correct, especially if you’ve moved or recently updated an EIN, DBA, or registered agent.

Taxpayer portal alerts

This is a common place where sellers miss updates. Even if you file quarterly or annually, log into each state portal at least monthly to check for new notices or system messages.

Frequency change notices typically include:

• Your new filing frequency
• The effective date
• Any prepayment requirements
• Updated filing or payment instructions (e.g., New York requires monthly filers to electronically file)
• State contact information

Timing Matters—When Do States Change Filing Frequencies?

Most states follow predictable review cycles tied to the calendar or fiscal year:

• January (beginning of year): many states reassess taxpayer history from the prior year and send notices to reflect new filing frequencies that go into effect January 1. These notices will typically come November-December.
• July (mid-year): states that follow fiscal year policies often issue new filing frequencies effective July 1. These notices typically come around May-June.

Both January and July can be considered “frequency checkpoints” for taxpayers to be aware of. However, some states run frequency reviews at less predictable times. That’s why it’s critical to monitor your filing status year-round.

State Examples

California

California’s CDTFA runs an annual system analysis that reviews:

• Account status and compliance history
• Average gross sales or tax volume

For example, if average monthly taxable sales exceed $17,000, CDTFA will switch the account to a Quarterly Prepayment frequency.

Once the account is flagged for change, the system automatically generates a Notice of Change in Reporting Basis to be mailed to the taxpayer before year-end. The taxpayer has before the end of the year to respond.

Colorado

Colorado assigns frequencies based on the amount of sales tax collected monthly.

Home-rule cities (i.e. cities that collect their own local sales tax) can request higher frequencies for high-volume sellers, which the DOR must approve before the change takes effect.

Notices are sent before the new frequency becomes active.

Florida

In Florida, all businesses are initially set up with a monthly or quarterly filing frequency depending upon the business type. However, the state Department of Revenue reviews each sales and use tax account annually to determine the correct filing frequency for the next calendar year.

Notices are sent via mail.

New York

New York initially assigns annual or quarterly filing frequencies, but adjustments occur based on liability. For example, a quarterly filer may change to annual if the total tax due for the previous four quarterly periods is $3,000 or less. Quarterly can also change to part-quarterly (monthly) if the taxpayer’s combined taxable sales during any quarter is $300,000 or more.

Although they don’t specify how, the New York State Department of Taxation and Finance states that the taxpayer will be notified if there are changes made to their filing frequency, and that the correct tax form will be automatically added to their taxpayer portal.

North Carolina

Sometimes, annual reviews for filing frequencies are done during times other than calendar or fiscal year cycles.

North Carolina completes an annual review using a 12-month period that ends on March 31. In 2025, notices of filing frequency changes were sent out in August, for an effective change date of October 1, 2025.

Can Businesses Change Their Filing Frequency Themselves?

Yes. Many states allow businesses to request a new filing frequency, though approval depends on your liability and compliance record. Here is some general guidance on changing your filing frequency.

When you might request a change

You might benefit from a different filing frequency if:

• Monthly filings overwhelm your team
• You’ve experienced a drop in sales that you anticipate will continue
• You would like your filings to align across states
• Your state offers incentives for more frequent filing (like Utah)

How to request a change

Most states allow businesses to request a different frequency during specific times or through specific channels. Here are some examples:

• Washington – if you want to change your filing frequency, Washington Department of Revenue instructs that you will need to speak to their call center at 360-705-6705.
• Arizona – you will need to download and complete a Business Account Update Form and mail it in. Online submissions of the form are not allowed, and requests will be completed during the next available filing period.
• Florida – if you qualify for a filing frequency change based on your annual sales tax collections, you can make a request by calling the Department of Taxpayer’s Assistance at 850-488-6800.
• Alabama – if you meet certain tax liability requirements, you can request a change in status once per year before February 20.

Quick tips to help your approval odds

• Ensure all prior filings are filed and paid on time
• Pay any outstanding balances
• Demonstrate reduced liability or consistently changed sales activity
• Submit requests before your next return is due or before year-end
