How to Fill Out Pennsylvania Form PA-3 (w/Examples) + FAQs

Pennsylvania Form PA-3 is the Sales, Use, and Hotel Occupancy Tax Return that every licensed Pennsylvania sales tax vendor must file with the Pennsylvania Department of Revenue to report taxable sales, remit collected sales tax, self-assess use tax, and pay hotel occupancy tax. The return is now filed almost entirely through the state’s myPATH portal, and the paper PA-3 is reserved for narrow exceptions because the Department of Revenue mandates electronic filing under 61 Pa. Code ยง 34.3.

Missing the 20th-of-the-month deadline, mis-keying the local 1% Philadelphia or 2% Allegheny tax, or skipping the use tax line triggers a 5% per month penalty up to 25%, plus interest at the federal short-term rate plus 2%. Pennsylvania processed more than 3.4 million sales tax filings in fiscal year 2024โ€“25, and the Department of Revenue has reported that roughly 1 in 7 paper PA-3 returns contain a math or local-tax error that delays processing or triggers an assessment notice, according to the agency’s REV-227 Retailer’s Information Guide.

What PA-3 Is and Who Must File It

Pennsylvania Form PA-3 is the periodic return that every holder of a Pennsylvania Sales, Use and Hotel Occupancy Tax license uses to report taxable receipts and pay the 6% state sales tax, the 1% Philadelphia local sales tax, the 2% Allegheny County local sales tax, the 6% use tax on untaxed purchases, and the additional hotel occupancy tax. The form is authorized by the Tax Reform Code of 1971, 72 P.S. ยง 7217, which requires every licensee to file even when no tax is due. The most recent printed revision is PA-3 (REV-2024), and you should confirm the revision date in the lower-left corner of the paper form before mailing.

You must file PA-3 if you hold an active sales tax license, even for a zero-sales period. The Department of Revenue assigns each licensee a filing frequency โ€” monthly, quarterly, or semi-annual โ€” based on actual or anticipated tax liability under 61 Pa. Code ยง 34.3. Monthly filers owe more than $600 in tax per quarter, quarterly filers owe between $300 and $2,400 annually, and semi-annual filers owe under $300 annually.

A common misconception is that marketplace sellers on Amazon or Etsy do not need to file. They still must file PA-3 to report any direct sales and to claim the marketplace facilitator deduction on Line 2, as explained in the Department’s marketplace sales guidance.

Before You Start: Documents and Information You Need

Pull these items together before you log in to myPATH or pick up a paper PA-3, because the portal session times out after 20 minutes of inactivity and a paper return with missing data gets bounced back. Each item below has a reason it matters and a consequence for skipping it.

  • 8-digit PA Sales Tax License number โ€” printed on your REV-1840 license certificate; without it myPATH cannot route your return.
  • Federal EIN or SSN โ€” used by the Department to cross-match against IRS records; a mismatch flags the return for manual review.
  • Filing period dates โ€” confirms the correct return; filing the wrong period creates a duplicate return and a phantom liability.
  • Gross sales total โ€” every dollar received from sales of tangible personal property and taxable services, taxed and exempt; under-reporting gross is an audit trigger.
  • Nontaxable and exempt sales detail โ€” backed by REV-1220 exemption certificates; without certificates, the Department disallows the deduction.
  • Local sales breakdown for Philadelphia and Allegheny โ€” the 1% and 2% local taxes are reported on separate lines; combining them with state tax causes a misallocation notice.
  • Use tax purchases โ€” out-of-state or untaxed buys for business use; ignoring this line is the #1 audit finding under 72 P.S. ยง 7202(b).
  • Hotel occupancy receipts โ€” separate from sales tax for lodging operators; missing this line triggers a separate hotel tax assessment.
  • Bank routing and account numbers โ€” required for ACH debit through myPATH; a wrong routing number causes a returned-payment penalty.
  • Prior period credit balances โ€” applied on Line 12; failing to claim them means you overpay and chase a refund.

Where to Get the Form and How to Access It

The official PA-3 lives on the Department of Revenue’s Sales, Use and Hotel Occupancy forms page, and the fillable PDF is titled REV-3 Sales, Use, Hotel Occupancy Tax Return. The Department publishes a fresh revision each year โ€” verify the (REV-2024) footer before you print. Do not download PA-3 from third-party sites, because outdated revisions use different line numbers that the scanner rejects.

For online filing, log in to myPATH using your existing credentials or click Create a Username if this is your first return. New filers must complete the myPATH registration and link their sales tax account using the Letter ID from any recent Department notice. The portal pre-fills your license number, name, and filing period, which removes the most common paper errors.

If you cannot file electronically, request a paper PA-3 through the Department’s Forms Ordering Service or call 1-800-362-2050. Mail-order paper forms arrive within 7โ€“10 business days, so order early. A misconception worth correcting: the Pennsylvania Tax Hub does not let you file PA-3 directly โ€” it only routes you to myPATH.

Step-by-Step: How to Fill Out PA-3 Line by Line

The walkthrough below tracks the myPATH screen flow and the printed paper PA-3 in parallel. Each H3 covers a single field, with plain-English instructions, an example entry in italics, an edge case, the most common mistake, and the misconception filers carry into the box.

Account Identification โ€” License Number

This top-of-form field asks for your 8-digit Pennsylvania Sales Tax License number, the unique ID the Department uses to post your payment. Enter the digits exactly as printed on your REV-1840 license certificate, with no dashes or spaces. Maria Lopez, who runs Lopez Bakery LLC, enters 12345678 in the License Number box.

If you operate multiple locations under one license, you still use one number โ€” Pennsylvania uses a consolidated license model under 61 Pa. Code ยง 34.2. The most common mistake is transposing two digits, which posts your payment to a stranger’s account and leaves you with a 5% late penalty even after you paid. A misconception filers hold is that the federal EIN can substitute for the license number on PA-3 โ€” it cannot, and the return will reject.

Account Identification โ€” Filing Period

This field asks what tax period the return covers, expressed as a month and year (monthly), quarter (Q1โ€“Q4), or half (H1/H2). Match the period to your assigned frequency in your myPATH dashboard, and never combine two periods on one return. Carlos Nguyen, a quarterly filer, enters 04/01/2026 โ€“ 06/30/2026 for the Q2 2026 return.

If you closed your business mid-period, file a final return for the partial period and check the Out of Business box on the paper form or the Cancel Account link in myPATH, as required by the REV-1706 cancellation form. The most common mistake is filing the wrong period, which creates a duplicate liability that is painful to unwind through the Board of Appeals. A misconception is that you can skip a zero-sales period โ€” you cannot, and skipping triggers a non-filer notice.

Line 1 โ€” Gross Sales

Line 1 asks for total gross receipts from all sales of tangible personal property and taxable services during the period, before any deductions. Enter the dollar amount rounded to the nearest whole dollar with no commas in myPATH. Aisha Brown, who runs an online retailer called BrownGoods, enters 84,250 on Line 1 for Q2 2026.

Include sales to exempt customers here โ€” the exemption deduction comes later on Line 2, not by netting it out of Line 1. The most common mistake is reporting only taxable sales on Line 1, which understates gross and triggers an audit when the Department compares your PA-3 against your federal Schedule C or Form 1120 gross receipts. A misconception is that shipping charges are excluded โ€” under 61 Pa. Code ยง 33.2, shipping charged on a taxable sale is itself taxable and must be in Line 1.

Line 2 โ€” Nontaxable and Exempt Sales

Line 2 asks for the portion of Line 1 that is not subject to sales tax, including resale, manufacturing, charitable, government, and marketplace facilitator sales. Enter the total dollar amount, and keep the supporting REV-1220 certificates in your records for at least three years. Aisha Brown enters 12,400 on Line 2, representing wholesale orders shipped to retailers who provided resale certificates.

For marketplace sales where Amazon or Etsy collected the tax, include those receipts on Line 2 and keep the marketplace’s collection report. The most common mistake is claiming exempt sales without a valid certificate on file, which the Department disallows on audit, leaving you owing 6% plus penalty and interest. A misconception is that food sales are automatically exempt โ€” only specific grocery items qualify under the REV-717 Retailer’s Information Booklet, and prepared food sold by restaurants is fully taxable.

Line 3 โ€” Net Taxable Sales

Line 3 is Line 1 minus Line 2, the figure on which 6% state sales tax is computed. myPATH calculates this automatically; on paper you compute it by hand and enter the result. Carlos Nguyen, owner of Carlos’s Cheesesteaks in Philadelphia, enters 41,800 on Line 3 after subtracting 1,200 in exempt catering sales from 43,000 gross.

If Line 3 is negative because of returns or allowances, enter zero and report the credit on Line 12 instead, as instructed in the PA-3 line-by-line instructions. The most common mistake is a math error that flows through every downstream line, which is why myPATH’s auto-calc is strongly preferred. A misconception is that Line 3 includes use tax purchases โ€” it does not; use tax has its own line below.

Line 4 โ€” State Sales Tax (6%)

Line 4 asks you to multiply Line 3 by 0.06 to compute the 6% state sales tax due. Enter the result rounded to the nearest cent. Carlos enters 2,508.00 on Line 4 (41,800 ร— 0.06).

If you collected more tax than 6% โ€” for instance, because you charged tax on an exempt item โ€” you must remit the full amount collected, not just the statutory 6%, under 72 P.S. ยง 7237. The most common mistake is rounding down to whole dollars, which creates a small underpayment that, repeated across periods, becomes an assessment. A misconception is that the 6% is a maximum โ€” it is the floor; over-collected tax is a trust fund liability you cannot keep.

Line 5 โ€” Philadelphia Local Sales Tax (1%) and Line 6 โ€” Allegheny Local Sales Tax (2%)

These two lines ask for net taxable sales sourced to Philadelphia (Line 5) or Allegheny County (Line 6), multiplied by 1% or 2% respectively. Sourcing follows the destination of the sale for delivered goods and the location of the seller for over-the-counter sales, per 61 Pa. Code ยง 60.16. Carlos’s Cheesesteaks, located in Philadelphia, enters 41,800 in the Philadelphia local taxable sales column and 418.00 on Line 5.

If you have sales in both Philadelphia and Allegheny, complete both lines separately โ€” never combine them. The most common mistake is failing to file the local tax on a delivery into Philadelphia from a suburban store, which is sourced to Philadelphia and owes the 1%. A misconception is that the local tax piggybacks on the state 6% automatically โ€” it does not; you must self-report it on Line 5 or 6.

Line 7 โ€” Use Tax

Line 7 asks for 6% use tax on untaxed purchases of taxable property or services used in Pennsylvania, including out-of-state online buys, equipment, and supplies where no sales tax was charged. Enter the taxable purchase base, then myPATH multiplies by 6%. Marcus Reilly, an HVAC contractor in Pittsburgh, enters 3,500 in untaxed purchases and 210.00 in use tax owed on Line 7.

If your purchase was sourced to Allegheny County or Philadelphia, also report the corresponding local use tax on Line 5 or Line 6. The most common mistake is leaving Line 7 blank when you bought equipment from an out-of-state vendor that did not charge tax โ€” this is the single most common audit adjustment in Pennsylvania, with assessments often spanning four years under 72 P.S. ยง 7258. A misconception is that use tax only applies to big-ticket items โ€” it applies to every untaxed taxable purchase, including software subscriptions used in PA.

Line 8 โ€” Hotel Occupancy Tax

Line 8 asks lodging operators for 6% state hotel occupancy tax on room rentals of less than 30 days, with separate columns for the 1% Philadelphia and 2% Allegheny local hotel tax where applicable. Enter taxable room receipts and let myPATH compute, or compute by hand on paper. Janet Park, who manages the Park Inn in Allegheny County, enters 56,000 in room receipts, 3,360.00 in state hotel tax, and 1,120.00 in Allegheny local hotel tax on Line 8.

Short-term rental hosts on Airbnb or Vrbo must file Line 8 even when the platform collects the state portion, because Act 109 of 2016 requires reporting. The most common mistake is omitting the local hotel tax in Allegheny or Philadelphia, which is administered separately under the Department’s hotel occupancy guidance. A misconception is that hotel tax replaces sales tax for lodging โ€” additional taxable in-room services, like meals, still go on Lines 1โ€“4.

Line 9 โ€” Total Tax Due

Line 9 is the sum of Lines 4, 5, 6, 7, and 8, representing the gross tax liability before any discount. myPATH computes this automatically. Carlos’s total on Line 9 is 2,926.00 (2,508 state + 418 Philadelphia local).

If Line 9 is zero, you still must file the return โ€” Pennsylvania is a strict zero-return state under 61 Pa. Code ยง 34.3. The most common mistake is hand-totaling on paper and missing the use tax line, which understates the liability and triggers a notice. A misconception is that Line 9 is the amount you pay โ€” the discount on Line 10 and credits on Line 12 still adjust it.

Line 10 โ€” Vendor Discount (1%)

Line 10 lets timely filers keep 1% of the state tax on Line 4 as a vendor’s collection allowance, capped at $25 per month or $75 per quarter under 72 P.S. ยง 7227. Enter the smaller of 1% of Line 4 or the cap. Carlos enters 25.08 on Line 10 (1% of 2,508), under the $75 quarterly cap.

The discount applies only to state sales tax (Line 4) โ€” not to local tax, use tax, or hotel tax. The most common mistake is taking the discount on a late-filed return, which the Department disallows under 61 Pa. Code ยง 34.3(c); claiming it anyway gets corrected with a notice. A misconception is that the discount applies to use tax โ€” it does not, because use tax is self-assessed, not collected from a customer.

Line 11 โ€” Net Tax Due After Discount

Line 11 is Line 9 minus Line 10, the amount due after the vendor discount. Carlos enters 2,900.92 on Line 11 (2,926.00 โ€“ 25.08).

If you are filing late, leave Line 10 blank and Line 11 equals Line 9. The most common mistake is netting the discount against the wrong figure, which mis-states the balance owed. A misconception is that the discount can create a negative number โ€” it cannot; it is capped by Line 4.

Line 12 โ€” Credit for Prior Overpayment

Line 12 lets you apply credits from prior periods that the Department has acknowledged in writing or that appear in your myPATH account. Enter the credit amount, but never more than Line 11. Aisha Brown applies a 215.00 credit from a Q1 amended return.

Unverified credits will be reversed by the Department, so confirm the credit balance in myPATH’s Account Summary before claiming. The most common mistake is claiming a refund check you already cashed as a credit, which doubles the recovery and triggers an assessment plus penalty. A misconception is that any refund-eligible amount can be a credit โ€” only posted overpayments qualify.

Line 13 โ€” Penalty and Line 14 โ€” Interest

Line 13 asks for 5% per month penalty (max 25%) on late payments, and Line 14 asks for interest at the federal short-term rate plus 2%, set annually in a Department interest rate notice. Compute from the original due date through the date of payment. If Carlos files 30 days late, he enters 145.05 on Line 13 (5% of 2,900.92).

myPATH auto-computes both lines based on the post date of payment, so e-filers rarely need to enter them manually. The most common mistake is computing penalty on the gross Line 9 instead of the net Line 11, which over-reports penalty. A misconception is that filing on time but paying late avoids penalty โ€” both filing and payment must be timely.

Line 15 โ€” Total Amount Due

Line 15 is Line 11 minus Line 12 plus Lines 13 and 14, the final remittance amount. Carlos’s Line 15 is 2,900.92, paid by ACH debit through myPATH.

If Line 15 is negative (a refund), check the Refund or Credit Forward box. The most common mistake is mailing a check without the PA-3 voucher, which delays posting. A misconception is that a $0 Line 15 means no filing is required โ€” it does not; you still submit the return.

Signature and Date

The signature block requires the filer’s printed name, title, signature, date, and daytime phone. In myPATH, the signature is electronic via your password and a click-through attestation. Maria Lopez signs as Owner on 07/18/2026 with phone 215-555-0142.

A paid preparer must sign the preparer block and enter their PTIN. The most common mistake on paper is an unsigned PA-3, which the Department treats as not filed and assesses penalties on. A misconception is that any employee can sign โ€” only an officer, owner, partner, or authorized agent under a REV-677 power of attorney may sign.

How to File the Completed Form

Pennsylvania accepts PA-3 through three primary channels, but the Department of Revenue mandates electronic filing for nearly all licensees under its e-file mandate. Choose the channel that matches your account status, and keep proof of filing for at least three years.

Online via myPATH is the default channel. Log in at mypath.pa.gov, select File a Return under your sales tax account, complete each line, and submit. Payment is made by ACH debit (free), credit card (2.49% convenience fee through ACI Payments), or ACH credit initiated from your bank. Processing is real-time, and the confirmation number is your proof of filing โ€” save the PDF receipt.

Paper PA-3 is allowed only for filers granted a hardship waiver under REV-330. Mail the completed return with a check payable to PA Department of Revenue to PA Department of Revenue, PO Box 280406, Harrisburg, PA 17128-0406. There is no filing fee, but checks must include your license number and period in the memo line. Processing takes 4โ€“6 weeks; send via certified mail with return receipt as proof.

TeleFile at 1-800-748-8299 is available for monthly filers with no local tax and no use tax, paying by ACH debit. Processing is real-time and the confirmation number is your proof. A misconception is that you can fax PA-3 โ€” the Department does not accept faxed returns.

What Happens After You File

Once myPATH accepts your PA-3, you receive an instant confirmation number and the return posts to your account within one business day. The Department of Revenue runs an automated math and cross-match check against your prior periods, your federal filings, and your marketplace 1099-K data, which can take up to 30 days. If everything reconciles, the return closes silently and the next filing period opens in your dashboard.

If the Department finds a discrepancy, it issues a Notice of Assessment or Adjustment detailing the proposed change. You have 90 days to file a Petition for Reassessment with the Board of Appeals under 72 P.S. ยง 7234, or pay the balance to stop interest. Ignoring the notice converts the assessment to a final liability that the Department can lien and levy.

A misconception is that a clean filing means immunity from audit. The Department audits sales tax under a four-year statute of limitations, extended to six years for substantial under-reporting, and can request your records at any point during that window per REV-39 audit notice procedures.

Mistakes to Avoid When Filling Out the Form

  • Skipping Line 7 use tax โ€” the #1 audit adjustment, costing 6% plus penalty and interest on every untaxed purchase.
  • Combining Philadelphia and Allegheny local tax โ€” misallocates the local distribution and triggers a county-level notice.
  • Claiming the vendor discount on a late return โ€” the Department disallows it and adds penalty.
  • Reporting only taxable sales on Line 1 โ€” under-states gross and triggers a federal-to-state mismatch.
  • Missing the 20th-of-the-month deadline โ€” kills the 1% discount and starts the 5% per month penalty clock.
  • Filing the wrong period โ€” creates a duplicate liability that takes months to unwind.
  • Skipping zero-sales returns โ€” generates a non-filer notice and a $5 minimum penalty per period.
  • Using an outdated PA-3 revision โ€” the scanner rejects old line numbers, causing the return to fail to post.
  • Rounding inconsistently โ€” small math errors compound into assessment notices.
  • Mailing without the voucher โ€” payment posts to the wrong account or sits unapplied.
  • Unsigned paper PA-3 โ€” treated as not filed, with full penalty.
  • Claiming exempt sales without a REV-1220 โ€” disallowed on audit, with the full 6% assessed.

Do’s and Don’ts

Do:

  • Do file through myPATH โ€” it auto-computes every math line and prevents 80% of filing errors.
  • Do save the confirmation PDF โ€” it is your only proof of filing if the Department later claims non-filing.
  • Do keep REV-1220 exemption certificates for at least three years, because audits routinely request them.
  • Do report use tax on Line 7, even small amounts, because the Department cross-checks marketplace data.
  • Do file zero returns โ€” non-filing penalties apply even when no tax is due.
  • Do verify your filing frequency annually โ€” the Department reassigns frequencies based on liability.

Don’t:

  • Don’t pay by credit card if you can use ACH debit โ€” the 2.49% fee adds up over a year.
  • Don’t combine local taxes on one line โ€” the Department distributes 1% and 2% separately.
  • Don’t sign a paper PA-3 in pencil โ€” the scanner rejects non-ink signatures.
  • Don’t claim the vendor discount when filing late โ€” it gets reversed and creates a small balance.
  • Don’t ignore a Notice of Assessment past 90 days โ€” appeal rights expire and the liability becomes final.
  • Don’t assume marketplace facilitators handle everything โ€” direct sales still go on PA-3.

Pros and Cons of Filing on Your Own vs. With a Professional

Pros of filing yourself through myPATH:

  • Zero cost โ€” the portal is free and ACH debit is free.
  • Real-time confirmation โ€” no wait for posting.
  • Auto-math โ€” every computed line is filled by myPATH.
  • Direct control โ€” you see exactly what was filed.
  • Faster amendments โ€” myPATH lets you amend in minutes.

Cons of filing yourself:

  • No second set of eyes on Line 7 use tax, the most missed line.
  • Time cost โ€” first-time filers often spend 2โ€“3 hours learning myPATH.
  • Audit risk if exemption certificates are not collected correctly.
  • No representation if the Department issues an assessment.
  • Steep learning curve for multi-jurisdiction sellers handling Philadelphia and Allegheny tax.

FAQs

Do I have to file PA-3 if I had zero sales this period?

Yes. Pennsylvania requires every licensee to file a PA-3 every period, even with zero sales, or face a non-filer notice and a minimum penalty.

Can I still file the paper PA-3 in 2026?

No. The Department of Revenue mandates myPATH e-filing for almost all licensees; paper is allowed only with an approved REV-330 hardship waiver.

Do I write my federal EIN or my PA license number in the License Number box?

No. Only the 8-digit Pennsylvania Sales Tax License number goes in that box; the EIN belongs in the federal ID field separately.

Is shipping taxable on Line 1?

Yes. Shipping charged on a taxable sale is itself taxable under 61 Pa. Code ยง 33.2 and must be included in gross sales.

Do I report marketplace facilitator sales on PA-3?

Yes. You include them in Line 1 gross and deduct them on Line 2 as exempt, so the Department sees the full picture.

Can I take the 1% vendor discount on use tax?

No. The discount applies only to state sales tax on Line 4, not to use tax, local tax, or hotel tax.

What goes in Line 5 if I sell from outside Philadelphia but ship into the city?

Yes, those delivered sales are sourced to Philadelphia and the 1% local tax goes on Line 5.

Is the filing deadline the 20th or the last day of the month?

Yes, the deadline is the 20th of the month following the period close, with a one-business-day extension if the 20th is a weekend or holiday.

Do Airbnb hosts file PA-3?

Yes. Short-term rental hosts file PA-3 with hotel tax on Line 8, even when Airbnb collects the state portion, to satisfy Act 109 reporting.

Can I amend a PA-3 after I file?

Yes. You file an amended return through myPATH using the Amend Return link, within three years of the original due date.

Does the discount on Line 10 apply if I file a day late?

No. Any late filing forfeits the entire vendor discount, even by one day.

What if I sign the paper PA-3 with a stamp signature?

No. The Department requires an original ink signature on paper; stamps are treated as unsigned and the return is rejected.

Do I need to attach exemption certificates to the PA-3?

No. Keep REV-1220 certificates in your records for at least three years; do not attach them to the return itself.

Is use tax on Line 7 only for big purchases?

No. Every untaxed taxable purchase triggers use tax, including software subscriptions, office supplies, and small equipment buys.
