Filing Frequencies: How States Dictate Your Payroll Tax Calendar

Ask a payroll professional how often they file payroll taxes, and they’ll usually start with the federal answer: semi-weekly or monthly, depending on their lookback period liability. What they’re less likely to tell you—unless they’ve been burned by it—is that each state has its own answer to that question, and that the state answers don’t necessarily align with the federal answer.

Managing filing frequency across multiple states is one of the more procedural challenges in multi-state payroll tax compliance. There are no complex calculations involved. The complexity comes purely from the number of different schedules that must be tracked and executed simultaneously.

Federal Deposit Schedules as Context

The IRS assigns deposit schedules based on an employer’s “lookback period” liability—the total employment taxes reported during a 12-month window ending June 30 of the prior year:

• Monthly depositors: Employers whose lookback period liability was $50,000 or less. Deposits are due by the 15th of the following month.
• Semi-weekly depositors: Employers whose lookback period liability exceeded $50,000. Deposits for wages paid Wednesday-Friday are due the following Wednesday; deposits for wages paid Saturday-Tuesday are due the following Friday.

New employers with no lookback history start as monthly depositors. The $100,000 Next-Day Deposit Rule overrides both schedules: if at any time during a deposit period the accumulated undeposited liability reaches $100,000, it must be deposited by the next banking day.

This federal framework is familiar. State frameworks are variations on the theme—but the variations are significant enough to require attention.

State Deposit Frequency Categories

Most states use some combination of the following deposit frequencies for income tax withholding:

Annual: Very small employers with minimal withholding liability file and pay once per year. Thresholds vary, but typically apply to employers withholding less than a few hundred dollars per year.

Quarterly: Common for small employers. Deposits and returns are due within a month after each calendar quarter ends (April 30, July 31, October 31, January 31).

Monthly: Deposits due monthly, with a quarterly or annual return filing. Many mid-size employers fall here.

Semi-monthly: Deposits due twice per month—typically on the 15th and last day of the month.

Semi-weekly: For larger employers, following a Wednesday/Friday schedule similar to federal.

Weekly: Some states assign weekly deposit schedules for large employers.

The thresholds that determine which category an employer falls into are set by each state independently. What qualifies as “large enough” for semi-weekly deposits in California may not reach that threshold in Oklahoma.

State-Specific Examples

California

California uses an Employer’s Withholding Tax Schedule with multiple frequency categories:

• Quarterly filers: Employers with prior-year withholding under $350
• Monthly filers: $350 to $500 in prior-year withholding
• Semi-weekly filers: Withholding of $500 or more per payroll or $7,000 or more per quarter

California also has an immediate deposit requirement: employers who accumulate $500 or more in withholding at any point must deposit within the same business day.

New York

New York categorizes employers into:

• Annual filers: Less than $700 in withholding per year
• Quarterly filers: $700 to $1,750 per quarter
• Monthly filers: $1,750 to $300,000 per year
• Quarterly filers (online filing required): Certain large employers

New York also distinguishes between withholding due dates and return due dates—deposits are due by certain dates, but the quarterly return (Form NYS-45) is a separate filing due after the quarter ends.

Texas

Texas Workforce Commission (SUI only—Texas has no income tax) uses:

• Quarterly reporting: All employers report and pay SUI quarterly
• Accelerated filers: Large employers with significant annual SUI liability may have accelerated payment requirements

Illinois

Illinois income tax withholding has categories including quarterly, monthly, and semi-weekly, with thresholds based on annual withholding amounts. Illinois also has specific rules about the timing of deposits relative to payroll dates.

The Threshold Change Problem

Filing frequency categories aren’t permanent. States reassign employers to different frequencies based on updated liability information, typically at the start of each calendar year. An employer whose annual withholding liability increased above a threshold will be moved to a more frequent deposit schedule effective January 1.

How do states communicate this change? Often, through a notice mailed to the employer’s registered address—which may or may not be current, may or may not reach the right person, and may or may not get properly actioned before the first payroll of the new year.

The consequence of missing a frequency change is real: even if you pay the full amount owed, paying it on the wrong schedule—depositing monthly when semi-weekly is required—results in failure-to-deposit penalties. The IRS and most states assess these penalties mechanically based on the timing of deposits relative to the assigned schedule, not based on whether the total amount paid was correct.

Return Filing vs. Deposit Filing

An important distinction that trips up many payroll teams: deposits and returns are separate obligations.

A deposit is the actual tax payment—getting money to the agency by the required date.

A return is the informational filing—the form that reconciles your payroll and tax calculations. Returns are typically filed quarterly or annually, regardless of deposit frequency.

You can be fully current on all your deposits and still receive a penalty for filing your quarterly return late. You can file an accurate quarterly return and still receive a failure-to-deposit penalty if your deposits were on the wrong schedule. These are independent compliance requirements.

Annual Reconciliation Returns

Beyond quarterly filings, most states require an annual reconciliation that ties total wages paid and taxes withheld during the year to the individual W-2s issued to employees. These annual reconciliation returns have their own deadlines—often January 31 or February 28—and their own filing methods (paper, state portal, or via the W-2 reporting process).

Missing the annual reconciliation deadline is a common and avoidable source of penalties. It gets lost because it doesn’t fit the regular quarterly rhythm that payroll teams are most attentive to.

Building a Compliance Calendar That Actually Works

The operational solution to filing frequency complexity is a comprehensive compliance calendar—one that includes, for each state:

• Deposit frequency and specific due dates
• Quarterly return due dates
• Annual reconciliation due dates
• Reminder dates for reviewing frequency category changes each January

This calendar needs to be actively maintained, not built once and forgotten. When the company adds employees in a new state, the calendar should be updated immediately. When annual rate notices arrive, that’s also the time to verify that deposit frequency assignments haven’t changed.

For companies managing many states, the calendar becomes a critical operational tool—and the difference between a team that’s always ahead of deadlines and one that’s always reacting to state notices.
