Pennsylvania employers file the PA-W3 quarterly reconciliation through the Department of Revenue’s myPATH portal at mypath.pa.gov, reporting total compensation paid, total Pennsylvania income tax withheld, and the deposits already made during the three-month period. The return is due on the last day of the month after each quarter closes. For 2026, the deadlines are April 30, 2026 for the first quarter, July 31, 2026 for the second, November 2, 2026 for the third (October 31 falls on a Saturday), and February 1, 2027 for the fourth (January 31 falls on a Sunday).1Pennsylvania Department of Revenue. 2026 Filing and Remittance Due Dates Electronic submissions count as on time if completed by 11:59 p.m. on the due date; paper returns are timely if postmarked by the deadline.
Who Has to File
If you pay wages to employees and are required to withhold federal income tax, you must also withhold Pennsylvania personal income tax and file the PA-W3 each quarter. That covers individuals, partnerships, corporations, nonprofits, government bodies, and single-employee businesses alike.2Commonwealth of Pennsylvania. Employer Withholding The rule catches anyone paying a Pennsylvania resident for work performed anywhere, or a non-resident for work performed inside the state.
File even for a quarter with no wages paid. The Department of Revenue expects a PA-W3 showing zeros, not silence.3Pennsylvania Department of Revenue. What Is the Difference Between a PA-W3 and the PA-501 for Reporting Employer Withholding Note the distinction between two forms that get confused: the PA-501 is the deposit statement you use to remit withholding during the quarter, and the PA-W3 is the reconciliation return that ties those deposits to the total tax owed once the quarter closes.
Know Your Deposit Schedule First
Your deposit frequency controls how the PA-W3 is laid out, because the return reconciles what you deposited against what you withheld. Pennsylvania assigns the schedule based on quarterly withholding volume:2Commonwealth of Pennsylvania. Employer Withholding
- Quarterly, if you withhold under $300 per quarter. You remit with the PA-W3 itself.
- Monthly, if you withhold between $300 and $999 per quarter.
- Semi-monthly, if you withhold between $1,000 and $4,999.99 per quarter.
- Semi-weekly, if you withhold $5,000 or more per quarter.
That frequency determines the number of period lines on your PA-W3. Quarterly filers enter a single figure. Monthly filers use three periods. Semi-monthly filers use up to six, and semi-weekly filers can use up to 27.4Commonwealth of Pennsylvania.

Filing Through myPATH
Electronic filing is mandatory if you issue ten or more W-2s or 1099s for the year, and it’s the practical choice below that threshold too.2Commonwealth of Pennsylvania. Employer Withholding
Log in to myPATH and open the employer withholding account from your Summary tab. Click “File Now” for the current period, or open “View Returns and Periods” to file for a prior quarter. The return displays five key lines: Total Compensation, Total PA Withholding Tax, Total Deposits for the Quarter, any overpayment, and any payment due.5Pennsylvania Department of Revenue. How Do I File a PA W-3 Quarterly Reconciliation Return for Withholding Tax
Total Compensation is gross wages paid during the quarter to all employees, before any deduction for insurance, retirement, or other items. You can adjust the figure on screen. Total PA Withholding Tax reflects Pennsylvania’s flat rate of 3.07 percent applied to taxable wages.6Commonwealth of Pennsylvania. Tax Rates The system auto-populates deposits from payments already processed through myPATH, but only fully cleared deposits appear. Payments made outside myPATH, or future-dated deposits still pending, have to be entered manually in the withholding tax column for each deposit period.
The Department suggests making deposit payments at least 48 hours before you file so the totals populate automatically.5Pennsylvania Department of Revenue.

Paying What You Owe
When the return shows a balance, myPATH prompts you to pay by ACH debit at the time of filing. ACH credit and credit or debit card payments are also accepted, though card payments carry a vendor convenience fee based on the amount of tax due.7Pennsylvania Department of Revenue. Employer Withholding Information Guide Quarterly-schedule filers, who don’t make separate deposits, remit the full quarter’s withholding tax with the return.
Paper Filing
If you issue fewer than ten W-2s and 1099s and prefer paper, you can mail the PA-W3. Enclose a check or money order payable to “PA Department of Revenue” if a balance is due. The mailing address depends on whether you’re sending payment; the Department publishes the current PO Box directory on its website. Postmark by the quarterly deadline.
Reciprocal-State Employees Change Your Totals
Pennsylvania has reciprocal tax agreements with Indiana, Maryland, New Jersey, Ohio, Virginia, and West Virginia. An employee who lives in one of those states but works in Pennsylvania can file Form REV-419 to stop Pennsylvania withholding, in which case you withhold for their home state instead.8Pennsylvania Department of Revenue. Employee’s Nonwithholding Application Certificate (REV-419) Send a copy of each completed REV-419 and its attachments to the Bureau of Individual Taxes at PO Box 280507, Harrisburg, PA 17128-0507. Those employees drop out of your Pennsylvania withholding totals on the PA-W3, so keep the paperwork straight before you reconcile.
Late Filing Penalties and Interest
Filing late or underpaying triggers a penalty of 5 percent of the tax due for the first month, plus 5 percent for each additional month the return stays unfiled, capped at 25 percent. The minimum penalty is $5.9Cornell Law Institute. Pennsylvania Code 61 Pa.

How the PA-W3 Feeds the Annual Reconciliation
The four quarterly PA-W3 filings roll up into the REV-1667, Pennsylvania’s annual withholding reconciliation. The REV-1667 is due January 31 following the tax year and must include copies of all W-2s and 1099s you issued.11Pennsylvania Department of Revenue. How Do I File the Annual Withholding Reconciliation (REV-1667) On myPATH, submit your income statements first (W-2s, 1099-Rs, 1099-MISC and 1099-NEC records), then wait at least 48 hours before filing the REV-1667 so the system can pull in the data.
The REV-1667 checks total compensation and total tax withheld for the full year against what your quarterly PA-W3 returns already reported. If the pre-populated numbers don’t match your records, you can adjust them manually. No payment goes with the REV-1667 itself; any balance should have been paid through the quarterly returns and deposits.12Pennsylvania Department of Revenue.

Correcting a Return You Already Filed
To correct a PA-W3 after submission, open the relevant period in myPATH and file a corrected return with the adjusted figures. For the annual reconciliation, the REV-1667 has an “Amended Statement” checkbox; mark it, enter the corrected totals, then sign and date the form.12Pennsylvania Department of Revenue.
