Year End Chores for S-Corporations

  • S-Corp returns must be filed by March 15. The late filing penalty with no extension is $220 per month, per shareholder. We will need your paperwork in Early February to avoid the need for filing an extension. Paperwork for your personal 1040 return can come later.


  • Reimbursements:  Reimburse shareholders and partners for personally paid travel, auto and other business expenses before Dec 31. You can also reimburse for prorated home office expenses if appropriate for your situation. All reimbursement arrangements should be documented. This is called an "accountable plan".
  • Officer Reasonable Salary:  A shareholder cannot take distributions (or "draws") from an S-Corp without first taking out a reasonable W-2 salary. This would typically be an amount comparable to the industry standard wages for similar work. Correcting low or nonexistent S-Corp owner payroll later can incur large penalties.
  • Health Insurance for Shareholders:  Health insurance paid (or reimbursed) by the company must be included as income on the shareholder's W-2, not subject to FICA taxes. You may need to catch up on these amounts in the final payroll run. Not reporting shareholder health insurance correctly is the most common S-Corp error I see. Scroll down for further information on correctly reporting this on the W-2.
  • Closing the books:  Certain year end entries must be made in Quickbooks to close out last year, and zero out some accounts for next year. This will be a matter for your bookkeeper. Scroll down for more details on closing the books.

If you and your bookkeeper have these year end chores squared away, you can start collecting your paperwork so we can prepare your annual tax return. We can directly access most client's Quickbooks accounts to download the reports we'll need to complete your tax return. If this is the case, you probably need to do nothing more than to ask your bookkeeper to do a year end reconcile and to let us know when everything is ready to go. Here is our   S-Corp tax preparation checklist.


Close the Books

** The work in this section is intended for your bookkeeper.   Please forward these instructions to that person. **

  • Prior year asset depreciation is usually entered in April after the annual taxes are filed. It's good practice to check that this was not forgotten. The current depreciation data can be found in the depreciation schedule usually located toward the back of your prior year tax return.
  • Clean up "Loans" that were really distributions. Ensure that true loans were documented with signed notes.
  • Reconcile the bank and liability accounts and confirm books really match the bank.
  • Prepare 1099-NEC and 1099-MISC for outside contractors paid more than $600 over the year. Contact us by January 10 if you want us to create, mail and file these forms.

Year End Journal Entries

The balance sheet equity section has several temporary accounts that need to be closed out at the end of the year so they can start fresh at zero for the new year. To do so, you'll need to make a few quick journal entries, all dated January 1 of the upcoming new year. You can confirm that you did this correctly if you change the date on your balance sheet report from 12/31 to 1/1.

  • Close out "Net Income" to "Retained Earnings: Debit Net Income so it becomes zero, and credit retained earnings by the same amount. (The default installation of Quickbooks should make this entry automatically).
  • "Contributions" or "Owner Contributions": You'll do the same: debit "Contributions" to bring it to zero and credit "Retained Earnings" by the same amount. (Quickbooks does not do this entry automatically)
  • "Distributions" or "Draws": In this case, since distributions is a credit account, you will Credit "Distributions" and debit "Retained Earnings". (Again, Quickbooks does not do this automatically)
  • Video Guide These excellent short videos by Candus Kampfer will show the entries to make.

How to include S-Corp Shareholder Health Insurance on the W-2

S-corporations can provide health insurance as a tax-free benefit to their non-owner employees and deduct the cost as an insurance business expense. However, getting tax-free health insurance for S-corp owners isn’t treated the same way.

Health insurance premiums paid (or reimbursed) for shareholder / owners, their spouses and dependents must be added to W-2 wages. The twist is that these amounts are exempt from Social Security or Medicare withholding if the plan is also available to other employees of the same class. On the W-2, the additional compensation is included in the shareholder-employee's Box 1 (Wages) of Form W-2, Wage and Tax Statement, but is not included in Boxes 3 and 5 of Form W-2. See the illustration below.

  • This amount added to the shareholder's wages for insurance increases the wage expense of the company, which reduces net income. Be sure to reduce the corporation's "employee health" insurance expense by this amount so you don't double dip this expense.
  • This amount can be deducted on the shareholder's personal 1040 to claim the valuable Self-Employed Heath Insurance Deduction.
  • The shareholder cannot take the insurance deduction if they or their spouse works for another company that offers free or subsidized health insurance, whether or not they choose to take it. There are other qualifications to taking this deduction, so it's best to check.

Bookkeepers: Note the reduction in Social Security and Medicare wages to match the $5000 Health Insurance expenditure on behalf of the shareholder. There is also a notation in box 14. See the links below to see how to set this up in Quickbooks.

Reimbursing the Shareholder if they personally paid for the insurance or has Medicare

If the qualifying shareholder buys a policy in their own name and personally makes the payments, the S-Corp must reimburse, then include the amounts in wages as described. The company is considered to have made the payments directly, and can take the expense. This can include all parts of Medicare, ACA Marketplace insurance, and insurance for the spouse and dependents.
All reimbursements should be made before the end of the year.
