1) Medical Premiums paid by > 2% owner - after-tax deduction on payroll or just don't deal with it within the payroll?===> Medical Premiums paid by > 2% owner - after-tax deduction? I guess it depends; The deduction is only allowed when the plan is established by the corp. as an owner/ employee of the S corp, you can buy the plan establsihed by the corp and be reimbursed by the corp.in this case it can be on payroll under the non accountable plan. In general , the total premiums must be reported on the more than 2% shareholder?s Form W-2 in the same year the premiums are paid in order for a greater than 2% shareholder in an S corp to deduct medical insurance premiums paid by the company on their behalf and of course the deduction needs to be on payroll of the S corp; If the corp has a single employee, who is also the officer of the corp and an owner, the employee status of the officer still allows the health insurance deduction however, Health insurance is deductible for any S Corp shareholder owning more than 2 %of the company and is not covered by other health insurance. While an officer of the company would be covered as an employee and the cost of health insurance deducted as an employee benefit, the deduction can be used by other owners if the company pays for the health insurance. For non-employee owners, insurance coverage can be in the business name, or an owner can buy private coverage and be reimbursed by the company.in this case it can be on payroll under the non accountable plan.
2) HSA Employee Contributions paid by > 2% owner - same question======>Same as above.
3) HSA Employer Contributions paid for > 2% owner- put on payroll? and therefore it will be on the W2 or don't deal with it in the payroll system at all?======>correct; say , you are a more than 2 % shareholder, then contributions by your S Corp to your HSA are also deductible, in the form of compensation, by the corp.For employment tax purposes, the S Corp treats the HSA contributions as wages subject to income tax withholding but exempt from FICA and Medicare taxes.So, you need to pick up the HSA contributions as income on your W-2, you may deduct the HSA payments made by the S Corp on your Form 1040 and, effectively, you have a wash for tax purposes. But the advantage is you save on payroll taxes by having the S Corp pay your HSA.
As said, S Corp owners who pay their medical insurance premiums personally are not eligible to claim the self-employed insurance deduction on page 1 of their Form 1040. The deduction is only allowed when the plan is established by the corp.
4) 401k contribution for > 2% owner - sounds like it must be on the payroll (pre-tax).======>>correct. you need to put your amount of retirement contributions on W-2 with Code as D.it needs to set up a payroll item for retirement benefits ,i.e,401K |
