QuickBooks help · Error codes
QuickBooks error codes, explained by ProAdvisors.
If QuickBooks just threw a code at you — H202, 6000-77, PS038, 3371, 15240, unrecoverable — this is the right page. Every common code explained: what it means, what causes it, whether you can self-fix, and when a ProAdvisor steps in. Independent firm — not Intuit.
QuickBooks error codes, the short version.
QuickBooks errors fall into six recognizable families: H-series (multi-user/network), 6000-series (file access/integrity), PS-series (payroll subscription/tax tables), 3000- and 80000-series (license/path), 15000-series (updates/maintenance), and unrecoverable / C-series (file corruption). These codes apply almost entirely to QuickBooks Desktop, Premier, Mac, and Enterprise — QuickBooks Online uses descriptive text messages, not numbered codes. Many first-occurrence errors clear with documented self-fix; errors that recur, cluster, involve corruption, or block critical work need a ProAdvisor’s file repair.

QuickBooks error codes, in five questions.
What are the most common QuickBooks errors?
Six families: H-series (multi-user/network), 6000-series (file access/integrity), PS-series (payroll subscription), 3371 and 80000-series (license/path), 15000-series (payroll updates), and unrecoverable / C-series (corruption). Most-searched individual codes: H202, 6000-77, PS038, 3371, 15240.
Are these Desktop or Online errors?
These codes apply almost entirely to QuickBooks Desktop, Premier, Mac, and Enterprise. QuickBooks Online uses descriptive text messages, not numbered codes — QBO errors are handled through different diagnostic approaches (browser, integrations, bank feeds).
Can I fix a QuickBooks error myself?
Sometimes. First-occurrence H-series, basic 6000-series, and most 15000-series errors often resolve with the QuickBooks Tool Hub, firewall checks, and the documented self-fix steps on each code’s page. Recurring errors, file corruption, and unrecoverable errors typically need a ProAdvisor.
When does an error need a ProAdvisor?
When self-fix didn’t resolve it, the error recurs after a fix, multiple errors appear together, you’re seeing file-corruption signals, or the error is blocking payroll, month-end, or AR/AP work. A ProAdvisor diagnostic typically scopes within a day.
Should I call Intuit or a ProAdvisor?
Intuit: billing, license validation, basic installation, payroll subscription verification. ProAdvisor: file repair, multi-user networking, recurring errors past Intuit’s first-line fix, time-critical work, errors requiring bookkeeping judgment. The two complement each other.

QuickBooks error codes, plainly.
QuickBooks errors fall into six recognizable families: H-series (H101, H202, H505 — multi-user and network connectivity), 6000-series (6000-77, 6000-301, 6189, 6190 — file access and integrity), PS-series (PS032, PS036, PS038 — payroll subscription and tax tables), 3000- and 80000-series (3371, 80070057 — license validation and file path), 15000-series (15215, 15240 — payroll updates and maintenance), and unrecoverable / C-series (file corruption and critical faults). The codes in this reference apply almost entirely to QuickBooks Desktop, Premier, Mac, and Enterprise; QuickBooks Online uses descriptive text messages rather than numbered codes — the main numbered exception being the generic Error 9999 (“Something’s not quite right”) browser-script message. The honest read: many first-occurrence errors resolve with documented self-fix steps (QuickBooks Tool Hub, firewall checks, configuration adjustments) — the dedicated page for each code walks you through them. But errors that recur, cluster, involve file corruption, or block critical work typically require a Certified ProAdvisor’s file repair, scoped as fixed-fee work after a 30-minute diagnostic.

Find your error’s family.
Most QuickBooks errors fall into one of these six families. Identify your code’s family, then scan the specific codes below. If your error isn’t resolving, a ProAdvisor diagnostic identifies the real cause.
H-series · Multi-user & network
Multi-user mode breaks; workstations can’t connect to the company file on the host. Caused by Database Server Manager configuration, hosting settings, firewalls, or path changes.
6000-series · File access & integrity
File access, permission, or corruption errors. The file is locked, in use, damaged, or in a path QuickBooks can’t reach correctly.
PS-series · Payroll
Payroll-specific errors: subscription validation, tax-table downloads, paycheck processing. Often tied to payroll service status more than to the file itself.
3000- & 80000-series · License & path
License validation, product registration, and file-path or qbregistration.dat errors. Often resolved with QuickBooks Tool Hub or reinstallation.
15000-series · Updates & maintenance
Payroll and product update errors — downloads failing, SSL/certificate issues, security settings interfering. Usually resolvable without file work.
Unrecoverable & C-series · Critical
File corruption or critical software faults. The most serious category — typically require ProAdvisor intervention rather than self-fix.
Multi-user mode & network errors.
H-series errors share a root: QuickBooks is configured for multi-user but a workstation can’t reach the company file on the host. The specific code narrows where in that chain the problem is.
Error H202
The most common H-series error. Workstation can’t communicate with the server hosting the file — typically Database Server Manager not running, hosting misconfigured, or a firewall blocking. Resolution requires touching both host and workstation. Full self-fix and HowTo on the dedicated page.
Error H505
Workstation thinks the company file is on another workstation, but that machine isn’t set up to host. Similar root cause to H202, but specifically a hosting-configuration issue. Resolution involves verifying which machine should host. Full self-fix and HowTo on the dedicated page.
Error H101
QuickBooks needs additional configuration to switch to multi-user mode. Often a sign of a fresh installation or a new workstation that wasn’t fully set up for multi-user. Resolution involves Database Server Manager configuration. Full self-fix and HowTo on the dedicated page.
Error H303
Similar pattern to H202 and H505 — multi-user mode breakdown between workstation and host. The same diagnostic approach (Database Server Manager, hosting settings, firewall, path) applies.
File access & integrity errors.
6000-series errors involve the company file itself — whether QuickBooks can open it, whether it’s locked, whether it’s damaged, or whether permissions are correct. The complete 6000-series overview covers every variant.
Error 6190 & -816
Single-user file open in multi-user mode, or the transaction log (.TLG) out of sync with the company file (.QBW). Often resolved by renaming .TLG and .ND files; persistent occurrences point to file-integrity issues.
Error 6000-77
QuickBooks can’t access the file path — usually a mapped network drive or external storage. Often resolved by moving the file local or using UNC paths instead of mapped drives. Permission issues are the second common cause.
Error 6000-301
File-damage variant of the 6000-series. The file has integrity issues needing repair via QuickBooks File Doctor or, more commonly, a ProAdvisor-level rebuild. Self-fix works only for surface-level damage. Full self-fix and HowTo on the dedicated page.
Error 6000-83
QuickBooks Desktop can’t open or restore the company file — most often when the file sits on a server or network share, when restoring a backup, or when folder permissions are wrong. Full self-fix and HowTo on the dedicated page.
Error 6073, -816
The company file is locked or in use — open on another computer in single-user mode, opened by another user, hosted on multiple machines at once, or on a read-only or synced network location. Full self-fix and HowTo on the dedicated page.
Error 6150, -1006
QuickBooks can’t open or create the company file — usually the .QBW file is damaged, is the wrong file type, or was quarantined by antivirus. Full self-fix and HowTo on the dedicated page.
Complete 6000-series reference
All 6000-variants in one place: 6000-77, 6000-80, 6000-83, 6000-301, 6000-832, 6147, 6189, 6190, and the patterns connecting them — the page to bookmark if you’re seeing multiple 6000-variants.
Payroll subscription & tax-table errors.
PS-series errors are payroll-specific and usually involve the payroll service subscription, the tax-table download, or paycheck-processing validation. Often resolvable by verifying subscription status before assuming a deeper problem.
Error PS038
Paychecks stuck in “Online to Send” status — typically created while offline, then unable to sync. Resolution involves identifying the stuck paychecks and re-sending them, sometimes with payroll-service support to clear the queue. Full HowTo on the dedicated page.
Error PS036
Payroll subscription validation failure — QuickBooks can’t confirm the payroll subscription is active. Common after billing changes, expired cards, or subscription transitions. First step: verify subscription status with Intuit directly. Full self-fix and HowTo on the dedicated page.
Error PS077
Tax-table download fails. Causes range from an outdated QuickBooks version to incomplete billing information to security settings (still relevant for some QB versions). Usually resolvable without ProAdvisor involvement.
PS032 & PS107
Variants in the PS family covering tax-table validation and paycheck-creation issues. Often share root causes with PS036 and PS077 — verify subscription and tax-table status first.
License, installation & file-path errors.
Errors in this family involve QuickBooks’ ability to validate its own license, register the product, or locate the company file via its expected path.
Error 3371
License validation failure — QuickBooks can’t validate the product license file (qbregistration.dat). Common after Windows updates, drive changes, or QB reinstalls. Typically resolved via Tool Hub or by recreating qbregistration.dat. Full self-fix on the dedicated page.
Error 80070057
Wrong file extension, file-path issue, or permission problem when opening a company file. Often appears after moving files between locations or when antivirus quarantines QB files. Resolution: verify the file extension, move the file local, check permissions.
Update & maintenance errors.
15000-series errors interrupt payroll updates or product maintenance releases. Often resolved without file work — the issues are usually in security settings, certificate validation, or download interruption.
Error 15240
Payroll update fails to download or install. Common causes: SSL/security settings, incorrect system time/date, or antivirus blocking the download. Resolution: verify settings, the system clock, and run as administrator. Full HowTo on the dedicated page.
Error 15215
Update server unavailable — QuickBooks can’t verify the digital signature on an update file. Usually a conflicting application blocking QB’s connection, or security settings. Resolution: identify and pause the conflicting app, verify settings.
Critical errors — the ones that need a ProAdvisor.
These errors indicate file corruption or critical software faults. Self-fix steps rarely resolve them durably; a ProAdvisor’s diagnostic is the appropriate path.
Unrecoverable Error
The most serious. QuickBooks crashes with a code like “00000 14775” or similar, indicating file damage or a critical software fault. Continuing to use the file without repair typically worsens the corruption. Stop, back up the file, and book a diagnostic.
C-series errors
C=224, C=43, C=51, others. Internal QuickBooks runtime errors — usually file corruption surfacing in specific operations (reports, reconciliation, multi-user). Persistent C-errors indicate the file needs a structural rebuild, not surface-level repair.
Multiple errors at once
If you’re seeing several different codes in the same week, the surface symptoms usually mask a single deeper file-integrity problem. The honest move: stop fixing each error individually and bring in a ProAdvisor for a comprehensive file cleanup.
Six signals it’s time to call a ProAdvisor.
Self-fix is the right first step for most errors. These six signals are when escalation makes more sense than another troubleshooting attempt.
Self-fix didn’t resolve it
You ran QuickBooks Tool Hub, followed the documented steps for your code, and the error persists — the signal the underlying cause is past the documented surface fix. A ProAdvisor’s diagnostic is appropriate.
The error keeps coming back
The fix worked, then within days the error returned. Recurring errors indicate the root cause wasn’t addressed — only the symptom was masked. A diagnostic finds the actual cause.
Multiple errors at once
You’re seeing more than one different error in the same week. That pattern almost always points to broader file-integrity problems rather than coincidentally separate issues.
File corruption signals
Unrecoverable errors, C-series errors, persistent 6000-series with damage variants. The file itself needs repair, not just configuration adjustments — QuickBooks file cleanup is the right engagement.
It’s blocking critical work
Payroll is stuck, month-end can’t close, AR collections are paused. When time matters more than cost, bringing in a ProAdvisor immediately beats continuing to troubleshoot.
You don’t have time to troubleshoot
Self-fix takes hours. If your time is worth more than the diagnostic fee, paying a ProAdvisor to resolve it in an hour while you focus on the business is the obviously correct call. It’s how most engagements start.
Diagnostic, then fixed-fee fix.
Every error-driven engagement starts with a 30-minute diagnostic. We identify the actual root cause, then scope the fix in writing — fixed-fee, no hourly billing, before any work begins.
30-minute diagnostic call
A Certified ProAdvisor reviews the error, the surrounding context (when it started, what triggered it, what self-fix you tried), and the file itself. Usually scheduled within a day or two.
Root cause identified
We tell you what’s actually causing the error — not just the surface symptom. That’s the diagnostic’s real value: distinguishing a one-off network issue from a file-corruption pattern that’s about to get worse.
Written fixed-fee scope
A fixed-fee engagement scope in writing — what we’ll do, what it covers, what it costs, how long it takes. No hourly billing, no scope creep. You decide whether to proceed.
Resolution & verification
We resolve the error and verify it’s gone — including reproducing the conditions that triggered it. Documented before/after for your records and your CPA. A broader file cleanup when more than one error needs work.
Prevention guidance
A written summary of what caused the error and how to prevent recurrence — configuration changes, workflow adjustments, or operational practices. Stopping the next error is part of the engagement.
Ongoing support if needed
If the pattern suggests you’d benefit from ongoing monthly bookkeeping with the same ProAdvisor team, we’ll say so — or decline the upsell if it’s not the right fit. No pressure either way.
Can’t find your code, or self-fix didn’t clear it?
A Certified ProAdvisor identifies the real root cause and scopes the fix in writing — fixed-fee, no hourly billing. Independent firm.
Certified ProAdvisors who’ve seen this code before.
Error codes look intimidating because they’re cryptic by design — QuickBooks doesn’t explain what H202 or PS038 actually means. But every error in this reference has been resolved many times over by Certified ProAdvisors. The diagnostic isn’t guesswork; it’s pattern recognition — matching the code, its context, and the file’s state against errors already solved.
