What Documents Does GM Financial Need to Verify Your Income?

Updated: May 26, 2026

Why Income Verification Matters

GM Financial (formerly AmeriCredit) is a direct lender — they set their own underwriting standards. Before approving your auto loan, they verify that your stated monthly gross income is accurate and consistent.

Walking into a dealership without income documents delays the deal and can cause stip (stipulation) requests after signing, which hold up your vehicle delivery.

Standard Documents Required

1. Most Recent Pay Stub (Required for Most Applicants)

Your most recent pay stub must show:

Employer name
Your name
Pay period dates
Gross pay for the period
Year-to-Date gross earnings
Pay date within the last 30 days (some dealers require within 15 days)

Bi-weekly employees: Bring your 2 most recent stubs (covering the last month).
Weekly employees: Bring your 4 most recent stubs.

2. W-2 Forms (Prior Year)

GM Financial often requests your most recent W-2 to:

Verify income stability year-over-year
Confirm employment with the same employer
Validate overtime or bonus income that shows on your current stub

If your income has increased significantly since your last W-2, bring a pay stub AND W-2 — the underwriter will verify the increase is sustainable.

3. Federal Tax Returns (for Self-Employed, Commission, or Multiple Income Sources)

Self-employed applicants must provide:

Last 2 years of complete federal tax returns (1040 with all schedules)
Schedule C for sole proprietors, or K-1 for partnerships/S-corps
GM Financial uses net self-employment income (after business expenses), typically averaged over 24 months

Commissioned workers may be asked for returns if commission income is a primary source and cannot be verified via pay stubs alone.

4. Offer Letter / Employment Verification Letter (New Employees)

If you started a new job within the last 30–60 days, your pay stub may not reflect your full income rate. Provide:

Signed offer letter on employer letterhead
Letter must state: position, start date, annual salary or hourly rate + hours
Some dealers also require a direct-verification call to HR

Note: GM Financial typically cannot count income from a job that has not started yet (future start date).

Before You Go: Calculate Your Monthly Income

Dealers sometimes miscalculate income. Use the GM Income Calculator to verify your own monthly gross income before arriving. Know your number. If the dealer’s figure differs from yours, ask how they calculated it.

Your monthly income directly determines your PTI ratio — and that affects the loan terms and maximum payment GM Financial will approve. For how DTI ratio interacts with your credit tier to affect approval, see DTI Ratio for Auto Loans and GM Financial Credit Approval Tiers.
