Pennsylvania’s Form UC-1 is the employer registration that opens your unemployment compensation tax account with the Department of Labor and Industry, and you file it through the state’s myPATH online portal within 30 days of the first date someone performs paid work for your business.1New York Codes, Rules and Regulations. Pennsylvania Code Title 43 – Section 795, Registration and Other Reports Once the Department processes the registration, it assigns a UC employer account number you’ll use for all quarterly wage and tax reporting from that point on.
Who Has to Register
Section 315 of the Unemployment Compensation Law reaches almost every entity that pays someone to work. Any person, corporation, unincorporated association, or other entity for whom an individual performs services for pay must register within 30 days after those services are first performed.1New York Codes, Rules and Regulations. Pennsylvania Code Title 43 – Section 795, Registration and Other Reports You register first; the Department determines liability afterward.
For most standard employers, UC liability starts the moment you employ one or more workers for any part of a day during a calendar quarter, regardless of the amount paid. Two categories work differently. Agricultural employers become liable only after paying $20,000 or more in cash wages in a calendar quarter or employing ten or more workers. Domestic employers — people hiring nannies, housekeepers, or other household staff — trigger liability by paying $1,000 or more in cash wages in a calendar quarter.
What to Gather Before You Start
Pulling these items together first makes the online session go faster:
- Federal Employer Identification Number (FEIN). If you don’t have one, apply with the IRS before you start the Pennsylvania registration.
- Legal business name and any trade names, exactly as they appear on your IRS documents and state filings.
- Physical addresses for every Pennsylvania location where you operate.
- The exact date your first worker started performing services. That date sets the 30-day clock.
- Your ownership structure: sole proprietorship, partnership, corporation, LLC, or another form.
- A short description of what the business does. The state uses this to assign a NAICS code, which feeds into your initial tax rate.
- Names, Social Security numbers, titles, and ownership percentages for all owners and officers.
How to File Through myPATH
Pennsylvania has moved employer tax registration to the myPATH portal. The old PA-100 paper form and the previous Online Enterprise Registration system are no longer the main route. Go to Pennsylvania Online Business Tax Registration through myPATH. New users can start the registration without creating an account first; existing myPATH users log in and select “Register New Business Tax Accounts.”2Commonwealth of Pennsylvania. Register My Business for Taxes The same session can cover unemployment compensation alongside other state business taxes, so you don’t have to run separate registrations for each one.
The portal walks through each section and asks for the information above. You submit electronically and receive a confirmation. If you get stuck, Employer Tax Services answers at 866-403-6163 or through UC Chat on weekdays from 7:30 a.m. to 4:00 p.m. Eastern.3Commonwealth of Pennsylvania.

The 30-Day Deadline and What a Late Filing Costs
The clock starts on the first date work is actually performed, not the day you decided to hire someone or signed an offer letter. You have 30 days from that first-services date to register.1New York Codes, Rules and Regulations. Pennsylvania Code Title 43 – Section 795, Registration and Other Reports
Section 802 of the UC Law treats willful failure to file a required registration as a summary offense. A conviction carries a fine of $500 to $1,500, up to 30 days of imprisonment, or both, and each unregistered person or entity counts as a separate offense.4Pennsylvania General Assembly. Pennsylvania Unemployment Compensation Law Registering a few days late is a far better outcome than not registering.
After You’re Registered: UCMS and Quarterly Reports
Once your account number is issued, quarterly wage and tax reporting runs through the UC Management System at uctax.pa.gov. UCMS handles report submission, payments, account updates, rate information, and Department correspondence.5Commonwealth of Pennsylvania. PA UC Tax Online Services Pennsylvania requires electronic filing.
Reports cover standard calendar quarters, each due by the end of the following month:
- January through March: due April 30
- April through June: due July 31
- July through September: due October 31
- October through December: due January 31
Staying current on these filings keeps your account in good standing and preserves the full credit against your federal unemployment tax, which matters for the FUTA calculation discussed below.
2026 Wage Base and New Employer Rates
The UC taxable wage base for 2026 is $10,000 per employee per calendar year.6Commonwealth of Pennsylvania. Yearly Tax Highlights You owe UC tax only on the first $10,000 of each employee’s wages for the year; once an employee crosses that threshold, no additional UC tax is due on their further wages that year.
Employers without an experience record get a standard new-employer rate. For 2026:
- Non-construction employers: 3.8220%
- Construction employers: 10.5924%
Construction employers pay a higher rate because the industry has historically generated more unemployment claims. After roughly two complete calendar years of paying wages and reporting, your account becomes eligible for an experience-based rate. The Office of UC Tax Services calculates that rate yearly from your claims history through June 30 of the prior year, using six components: a reserve ratio factor, benefit ratio factor, state adjustment factor, surcharge adjustment, additional contributions factor, and interest factor. Employers with few layoffs tend toward lower rates; frequent claims push rates up.7Commonwealth of Pennsylvania. UC Tax
If You’re Taking Over an Existing Business
Acquiring a Pennsylvania business through a sale, merger, or any other transfer triggers a separate obligation. Both you and the previous owner must report the transfer to the Department within 30 days.1New York Codes, Rules and Regulations. Pennsylvania Code Title 43 – Section 795, Registration and Other Reports This applies to any transfer of an organization, trade, business, or workforce, and it’s distinct from initial registration.
As the successor, you can apply to have the previous owner’s experience record and reserve account balance transferred to your account. The Department grants the transfer only if it finds that your anticipated employment risk has a direct relationship to the predecessor’s experience, meaning you’re continuing essentially the same business activity.8Legal Information Institute. Pennsylvania Code 34 Pa. Code 63.1 – Successors-in-interest A good predecessor record can mean a lower rate for you; a bad one carries over too.
Moving employees to a new entity solely to secure a lower tax rate is illegal. The federal SUTA Dumping Prevention Act of 2004 requires states to impose civil and criminal penalties on anyone who knowingly sets up such arrangements or advises others to do so.9GovInfo.

Nonprofit and Government Option
Political subdivisions and organizations exempt under Internal Revenue Code Section 501(c)(3) can elect a reimbursable method instead of paying a standard contribution rate. Under reimbursable status, you don’t pay a quarterly tax rate; you reimburse the UC Fund dollar-for-dollar for benefits actually charged to your account, plus half of any extended benefits.10Commonwealth of Pennsylvania. Reimbursable Employers Whether the election saves money depends on turnover: low-turnover organizations often pay less this way, while frequent layoffs can make it more expensive than the standard rate. UCMS includes a collateral calculator and solvency fee tools for reimbursable accounts.5Commonwealth of Pennsylvania. PA UC Tax Online Services
Records You Must Keep
Pennsylvania’s regulations at 34 Pa. Code § 63.64 require every employer, including those who classify their workers as independent contractors, to maintain detailed payroll and employment records for each worker:
- Social Security number, full name, wage rate, and total pay for each pay period broken down by type.
- Place of employment, scheduled and actual hours worked, and daily attendance.
- Date and reason for separation when a worker leaves.
- Payment documentation: bank statements, canceled checks, check stubs, or EFT records.
- Any contract between you and the worker, plus any staffing or leasing contract with a third party.
- If a worker is treated as an independent contractor, all records supporting that classification.
Keep these records for at least four years after paying the contributions they relate to; daily attendance records have a shorter two-year minimum. Department representatives can inspect, copy, or transcribe them along with your general business records at any reasonable time.11Legal Information Institute. Pennsylvania Code 34 Pa. Code 63.64 – Records to Be Kept by Employer The IRS separately requires employment tax records to be kept at least four years after filing the fourth-quarter return for the year.12Internal Revenue Service. Employment Tax Recordkeeping Four years is a safe baseline for payroll retention.
How Pennsylvania Registration Ties to Federal FUTA
Registering in Pennsylvania handles the state side. Most employers also owe federal unemployment tax under FUTA. For 2026, the FUTA rate is 6.0% on the first $7,000 of each employee’s wages.13Internal Revenue Service. 2026 Publication 15 Paying your Pennsylvania UC tax on time earns a credit of up to 5.4%, dropping the effective federal rate to 0.6%. FUTA is paid entirely by the employer and never withheld from employee wages.14Internal Revenue Service. About Form 940, Employer’s Annual Federal Unemployment (FUTA) Tax Return
Report and pay FUTA each year on Form 940, due January 31 of the following year. If you deposited all FUTA tax on time throughout the year, you get an automatic 10-day extension to February 10.15Internal Revenue Service. Instructions for Form 940 Falling behind on Pennsylvania quarterly payments can cost you the 5.4% credit, which is a far bigger hit than the state tax itself.
