What payroll deadlines should employers track?

Payroll Tax Deadlines for Employers in Oregon

Employers operating in Oregon must stay on top of payroll tax deadlines to ensure compliance and avoid penalties. Timely filing and payment of payroll taxes are critical components of smooth business operations.

Key Payroll Tax Deadlines

• Federal Payroll Tax Deposits: Employers must follow the IRS deposit schedule, which can be semi-weekly or monthly based on the total tax liability. Deposits include Social Security, Medicare, and federal income tax withholding.
• Oregon State Income Tax Withholding: Oregon requires employers to deposit withheld state income taxes electronically. Deposit frequency is determined by the amount withheld, with monthly or quarterly schedules common.
• Oregon Employer Payroll Tax Returns: Employers must file Form OQ (Quarterly Tax Return) reporting state income tax withheld and unemployment insurance contributions. These returns are due quarterly, typically by the last day of the month following the quarter end (April 30, July 31, October 31, January 31).
• Oregon Unemployment Insurance (UI) Taxes: UI tax payments are generally due quarterly, coinciding with the quarterly tax return deadlines.

Operational Tips for Managing Payroll Deadlines

• Automate Payroll Processing: Use payroll software that integrates federal and Oregon state tax calculations and reminders to avoid missed deadlines.
• Maintain Accurate Records: Keep detailed payroll records to support filings and resolve discrepancies quickly.
• Schedule Regular Reviews: Periodically review deposit schedules and tax rates as they can change annually.
• Coordinate with Bookkeeping: Ensure payroll tax payments sync with accounting systems for accurate financial reporting.

As of 2026, always verify deadlines with official Oregon Department of Revenue and Oregon Employment Department resources to stay current with any updates.
