South Carolina WH-1605 Filing Stumps Some QuickBooks Users

QuickBooks users in South Carolina who need to file the state quarterly withholding reconciliation have reported trouble locating Form WH-1605 in the software and understanding which fields require manual entry. While the form itself is a standard state-mandated filing, the way QuickBooks handles it — pre-filling most fields but leaving a handful blank — has led to repeated questions on community boards about how to complete the return without error.

Background

Form WH-1605 is South Carolina’s quarterly income tax reconciliation return. It must be filed for the first three calendar quarters (due April 30, July 31, and October 31). For the fourth quarter, South Carolina requires a different form, WH-1606, which serves as the annual reconciliation. QuickBooks Desktop with payroll features automatically populates most of the WH-1605 fields using company, employee, and payroll data stored in the file. In many cases, this means users simply need to review the prefilled numbers and file — but when fields are left empty, confusion sets in.

The Issue

The common complaint is twofold: first, users cannot always find the WH-1605 form within QuickBooks after navigating to the payroll forms area; second, even when the form opens, fields like Line 2 (total deposits made) or Line 5 (penalty and interest) may be blank. The software does not estimate penalty and interest, and deposits are pulled from internal payroll liability records — but if those records are incomplete or if data was entered outside QuickBooks, the field stays empty. Some users also overlook the need to enter the South Carolina withholding number in a specific nine-digit format (e.g., 25999999-9).

Symptoms

Affected users report:

• The WH-1605 form is grayed out or missing from the list of state forms.
• Prefilled totals for wages and withholding appear correct, but Line 2 shows $0 despite having made deposits.
• A warning that the withholding number is missing or incorrectly formatted.
• Inability to file because the software will not proceed without penalty/interest figures (Line 5) filled in.
• Confusion about whether to check the “No longer reporting” box and what close date or explanation to provide.

Affected Product and Version

The issue appears across several recent releases of QuickBooks Desktop Pro, Premier, and Enterprise with the Enhanced Payroll or Assisted Payroll subscription. Users running QuickBooks 2021 through 2024 have reported it. The problem may also affect QuickBooks Desktop for Mac, though the form layout differs slightly. The underlying cause is not a software bug; rather, it is a mismatch between what QuickBooks can derive from payroll records and what users expect it to fill automatically.

Resolution

The top-rated community answer walks through the form step by step. First, verify that the South Carolina withholding number is entered correctly — nine digits beginning with “25,” hyphenated after the first digit (e.g., 25999999-9). This number must be set up in the payroll item list or payroll setup. If the number is correct but the form still will not populate, a rebuild of the payroll data may be needed.

For Line 2, QuickBooks calculates deposits from the payroll liability account, but only if the deposits were actually recorded in the software. If deposits were paid through a separate system, users must manually enter the total. Line 5 (penalty and interest) is never auto-filled because QuickBooks cannot know if the payment was late; South Carolina provides an online penalty calculator at sctax.org.

When no payment is due, South Carolina allows TeleFile by phone. The community solution emphasizes that the “Authorization” yes/no boxes near the bottom should be checked if the preparer is authorized to discuss the return — a step many miss.

For cases where the form simply will not appear, the fix often involves running QuickBooks payroll updates to download the latest form version, then restarting the software. If that fails, re-selecting the form from the “Payroll Forms” list and clearing any previously saved draft can reset it.

Takeaways

The WH-1605 is a straightforward quarterly return, but QuickBooks’ partial automation means users must manually fill only a few specific fields. Knowing which fields stay empty — and why — saves time and prevents filing errors. For users who need additional guidance on payroll forms in general, QuickBooks Users maintains a library of step-by-step articles. Keeping payroll subscriptions and tax table updates current also ensures the software has the most recent form revision loaded. No special workaround is required; a careful review of the prefilled data and a quick check of the withholding number format resolve the vast majority of cases.
