SBA Form 3508: PPP Loan Forgiveness Step-by-Step

SBA Form 3508 is the full-length application for Paycheck Protection Program loan forgiveness, and you fill it out by working from the back page forward: complete the Schedule A Worksheet first, roll those totals into Schedule A, carry Schedule A into the Forgiveness Calculation on page 1, and sign the certifications on page 2. Submit the finished package through your lender or through the SBA’s direct forgiveness portal at directforgiveness.sba.gov, which has been open to all borrowers regardless of loan size since March 2024.¹ Before starting, confirm you actually need the standard form: Form 3508S is available for loans of $150,000 or less, and Form 3508EZ works if you didn’t reduce headcount or cut any employee’s wages by more than 25% (or qualify for a safe harbor). The full 3508 is for larger loans that can’t certify those conditions. It works for anyone, but it takes the most math and the most documentation.

Set Your Covered Period First

Every calculation on the form depends on the covered period, so pin it down before you write anything. The default is 24 weeks (168 days) starting on the date your PPP loan was disbursed. Borrowers who received their loan before June 5, 2020, could choose an 8-week (56-day) period instead.² For First Draw loans, the covered period cannot extend past December 31, 2020.

If your payroll runs biweekly or more frequently, you can also elect an Alternative Payroll Covered Period that begins on the first day of the first pay period after disbursement rather than the disbursement date itself.² The form has fields for both; fill in whichever one you’re using.

Gather Your Documentation

The worksheet feeds Schedule A, which feeds the main calculation. Missing records at the bottom of that chain means redoing work at the top, so pull everything together first.

Payroll Records

Payroll is the backbone: at least 60% of the forgiven amount must come from payroll costs. You need:

IRS Form 941 (or equivalent payroll processor reports) for all quarters overlapping your covered period, plus state quarterly wage and unemployment insurance tax filings.¹
Payroll reports showing gross wages for each employee during the covered period, broken out by pay period.
Records of employer-paid health insurance premiums, retirement plan contributions, and state or local payroll taxes assessed on employee compensation.

Owner-employees and self-employed individuals have a compensation cap: forgiveness for owner pay is limited to $20,833 for a 24-week covered period or $15,385 for an 8-week covered period, calculated from 2019 net profit.³

Non-Payroll Expenses

Non-payroll costs are eligible only if the underlying obligation existed before February 15, 2020.¹ Have on hand:

For mortgage interest, the lender’s amortization schedule plus receipts or account statements showing covered-period payments.
For rent or lease payments, the lease agreement and receipts, cancelled checks, or account statements.
For utilities, invoices with proof of payment.
For covered operations expenditures and supplier costs, invoices, purchase orders, contracts, and proof of payment. Supplier contracts must have been in effect before the covered period, except for perishable goods.¹

Work the Form From the Back Forward

Form 3508 is a four-page package, and it’s built to be completed in reverse: Schedule A Worksheet, then Schedule A, then the main calculation on page 1, then the certifications on page 2.³

Page 4: Schedule A Worksheet

The worksheet has two employee tables. Table 1 lists every employee whose annualized cash compensation was $100,000 or less. Table 2 lists everyone above that threshold. For each Table 1 employee, compare their average pay rate during the covered period to their pay rate during the first quarter of 2020 (January 1 through March 31). If any employee’s pay dropped by more than 25%, the excess reduction gets subtracted dollar-for-dollar from your forgiveness amount.

The worksheet also calculates Full-Time Equivalency. Divide each employee’s average weekly hours during the covered period by 40 to get their FTE (capped at 1.0). You can simplify by assigning 1.0 to anyone who averaged 40 or more hours per week and 0.5 to everyone else. Total the individual FTE values for use on Schedule A.

Page 3: PPP Schedule A

Schedule A pulls the worksheet totals together. Lines 1 through 5 capture cash compensation totals, average FTE counts, and the salary reduction amount from each table. Lines 6 through 8 add non-cash payroll costs: employer-paid health insurance, retirement contributions, and state and local payroll taxes. Line 9 captures owner compensation. Line 10 sums everything into total payroll costs.³

Lines 11 through 13 produce the FTE Reduction Quotient. Compare your average FTE during the covered period (Line 12) against a reference period: either February 15, 2019 through June 30, 2019, or January 1, 2020 through February 29, 2020, whichever is more favorable. Divide covered-period FTE by reference-period FTE to get your quotient (Line 13). A result of 1.0 or higher means no FTE-based reduction.

Page 1: Forgiveness Calculation

The top section collects your business name, address, TIN, SBA loan number, lender loan number, loan amount, disbursement date, employee counts, and covered period dates. A checkbox flags loans over $2 million for automatic SBA review.

The forgiveness math runs through eleven lines:

Line 1: Total payroll costs from Schedule A, Line 10.
Lines 2–4: Business mortgage interest, rent or lease payments, and utility payments.
Line 5: Total salary/wage reduction from Schedule A, Line 3.
Line 6: Add Lines 1 through 4, then subtract Line 5.
Line 7: FTE Reduction Quotient from Schedule A, Line 13.
Line 8: Multiply Line 6 by Line 7.
Line 9: Your PPP loan amount.
Line 10: Line 1 divided by 0.60. This is what enforces the 60% payroll rule.
Line 11: Your forgiveness amount, which is the smallest of Lines 8, 9, and 10.³

That final “smallest of” is where most borrowers see forgiveness get capped. Spend less than 60% on payroll and Line 10 pulls the number down. Let FTE slip without qualifying for a safe harbor and Line 8 does the same.

Page 2: Certifications

Page 2 is a set of representations you sign under penalty of federal criminal law. You are certifying the information is accurate, the funds went to eligible purposes, and you applied the FTE and wage reduction rules correctly. False statements can carry up to 30 years imprisonment and a $1,000,000 fine under 18 U.S.C. 1014.³

How FTE and Wage Cuts Reduce Your Forgiveness

p>Two things can shrink the forgiveness amount below what you actually spent: losing employees and cutting pay.

The FTE Reduction Quotient scales your forgiveness by your headcount change. Go from 10 FTE to 8 and your quotient is 0.80, so Line 6 gets multiplied by 0.80 before any other cap applies. This is the biggest reduction most borrowers face on the standard form.

Separately, for any individual Table 1 employee whose annualized salary or hourly wage was cut by more than 25% compared to January 1 through March 31, 2020, the amount exceeding that 25% threshold is subtracted dollar-for-dollar.

Safe Harbors

You can avoid the FTE reduction entirely if you meet one of two safe harbors:

FTE Reduction Safe Harbor 1: Your business could not operate at its pre-February 15, 2020 level because of compliance with COVID-19 safety requirements issued by federal agencies (including state and local orders based on federal guidance). Keep documentation of the specific requirements that affected operations.³
FTE Reduction Safe Harbor 2: You reduced FTE levels between February 15 and April 26, 2020, but restored them by December 31, 2020, to the level in the pay period that included February 15, 2020.⁴

You can also exclude specific FTE reductions caused by employees who voluntarily resigned, were fired for cause, or rejected a good-faith written offer of rehire at the same salary and hours. Keep the written offers and any rejection responses; the SBA may ask for them.

The 60% Payroll Floor

At least 60% of the forgiven amount must have gone to payroll costs. Spending less than that doesn’t wipe out forgiveness entirely, but Line 10 caps it proportionally. Example: $50,000 spent on payroll out of a $100,000 loan caps forgiveness at $83,333 ($50,000 ÷ 0.60), not the full loan.

Submitting the Application

You have two submission paths. You can submit the completed application and supporting documents through your lender, typically via their online portal, though some lenders accept physical or emailed packages. Alternatively, all borrowers can use the SBA’s direct forgiveness portal at directforgiveness.sba.gov, which routes your application to your lender after you register and apply.⁵

Keep a complete copy of everything you send: the form, Schedule A, the worksheet, and every supporting document. You’ll need it if the SBA or your lender asks questions, and you’ll need it for your records for years afterward.

The original deadline was 10 months after the last day of your covered period. If you missed that, loan payments are no longer deferred and you should already be making monthly payments to your lender.¹ Borrowers who haven’t complied may be referred to Treasury for offset or cross-servicing, which can intercept tax refunds or other federal payments to recover the debt. Even past the 10-month mark, filing is still possible and still worth doing. Deferment won’t come back, but qualifying spending can still be forgiven.

What Happens After You Submit

The review runs in two stages. Your lender has 60 days to evaluate your documentation and submit a decision to the SBA. If the lender approves, the SBA then has up to 90 days to conduct its own review and remit the forgiveness payment (including accrued interest) to the lender.⁶ Total elapsed time can reach roughly 150 days. Loans exceeding $2 million are automatically flagged for SBA review, so if you’re in that range, every figure on the form should be tied to a document you can produce.

If Forgiveness Is Denied

If the SBA denies forgiveness in whole or in part after its loan review, you can appeal to the SBA’s Office of Hearings and Appeals. You have 30 calendar days from receipt of the final SBA decision to file, and filings must go through the portal at appeals.sba.gov; filings sent any other way may be rejected.⁷

Your petition must include a copy of the SBA decision being appealed, a detailed statement explaining why it was wrong with supporting facts and legal arguments, and your contact information (or your attorney’s).⁷ To keep the loan in deferment while the appeal is pending, give your lender a copy of the filed appeal.

One boundary worth knowing: OHA only reviews final SBA decisions. If your lender denied the application before it ever reached the SBA, that dispute goes back to the lender directly.⁷

Records to Keep

Hold onto every document tied to your PPP loan and forgiveness application for at least six years after the loan is forgiven or repaid in full. The SBA extended lender record-retention requirements through a 2024 Federal Register notice, and the agency retains the right to review loans for potential misuse of funds even after forgiveness is granted.⁸ Keep the completed Form 3508, Schedule A, the worksheet, all payroll and expense documentation, bank statements showing fund disbursement, and any correspondence with your lender or the SBA.
