Completing South Dakota Form 21 Page 2: Lines 10 and 15 in QuickBooks

QuickBooks Desktop users responsible for South Dakota unemployment insurance tax filings have raised questions about how to properly complete the detail worksheet on page 2 of Form 21 — specifically the sections tied to Line 10 and Line 15 on the form’s first page. The confusion generally centers on which fields populate automatically, which require manual entry, and how to activate the page in the first place.

When Page 2 Applies

Page 2 of South Dakota Form 21 is not part of the routine quarterly filing. It comes into play only when a business has discontinued operations in South Dakota, experienced a change in ownership or business structure, or needs to report adjustments applied to prior quarters. For most employers in steady operation, this page remains untouched.

Activating the Page

The most common stumbling block is that page 2 does not appear as an editable form by default. To generate the Line 15 detail section, you must check the corresponding box on Form 21, page 1, at Line 15. Similarly, if you have entered an amount on page 1 at Line 10, the program expects you to complete the Line 10 section on page 2. Without those triggers on the first page, the second page’s relevant sections remain inactive.

What Fills Automatically

QuickBooks carries over certain identifying information from page 1 so that you do not have to re-enter it. The business account number, legal business name, and mailing address all flow from the data you already entered on the first page of the form. Everything else on page 2 requires your direct input.

Business Discontinuation Details

If the business has closed without a successor, you must enter the date of last employment — or the date wages were last paid, whichever is later — and sign the form in the designated area. For a business that was sold, leased, or otherwise transferred, several additional fields come into play:

• Effective date of disposition — the date the transaction took effect.
• Reason for disposition — a brief explanation of why the business changed hands.
• Date wages were last paid in South Dakota — the final payroll date in the state.
• Retention status — you must indicate whether you are retaining any part of the business.
• Successor information — the name and address of the successor or successors.

South Dakota unemployment insurance law allows the transfer of an employer’s payroll experience and experience rating account to a successor. You will need to specify whether you authorize that transfer.

Signature Requirements

The form must be signed by the appropriate party. For an individual employer, that means the individual themselves. For a corporation, the president, treasurer, or another principal officer must sign. In other cases, a duly authorized member or agent with knowledge of the company’s affairs may sign.

Reporting Adjustments

The adjustments section covers corrections to previously filed quarters. You will need to enter the quarter or quarters the adjustments apply to, along with an explanation for each. This includes responses to debit or credit notices received from the South Dakota Department of Labor as well as any adjustments you discovered on your own from prior reporting periods.

The Key Takeaway

The bulk of page 2 is manual entry. QuickBooks handles the account number, business name, and address automatically, but the substantive details — dates, explanations, successor information, and authorization decisions — all fall to the person preparing the return. Making sure the correct boxes are checked on page 1 is the critical first step; without that, the detail sections on page 2 will not engage.

For users who regularly deal with state payroll tax forms inside QuickBooks, understanding which fields are program-driven versus manual can prevent filing errors and reduce back-and-forth with state agencies.
