S Corps don't pay self-employment taxes. You would withhold 7.65 percent from your salary and match that as the employer portion (and are able to write off half), which equals the same 15.3 percent you would have paid in SE tax; however, you are only paying it on the salary portion. Knowing that the IRS is not super aggressive about social security taxes, and also knowing that S Corps (under a million dollars in profits) have extremely low audit rates (especially if you take most of your deductions away from the normal audit-triggering 1120 S form (on Line 19--a separate written schedule of "other deductions"), I take a very modest salary, have a lot of write-offs--including employee's business use of personal vehicle (who needs mileage deductions when you get depreciation?), and collect the rest SE-tax free as a distribution. Dividends are not subject to SE tax. Yes, the IRS COULD say my salary is too low, but that's only if I get audited, which is slim, and I have many deductions to substantiate a lower salary, so I can put up a good case if challenged. Bottom line: In aggressive tax avoidance, it's better to beg forgiveness than to ask permission. If you work the legitimate deductions on an S Corp the right way (on Line 19) and pay yourself around $1,000 a month taking the rest as distributions, you're probably okay. Worst case, you will have to pay the back SE tax on a recalculated salary IF you get audited and IF you give in (you can fight rather effectively with the use of Affidavits and squash the IRS if you know the system). I know several people who pay themselves no salary at all for a few years in the beginning and have not been audited. The IRS simply isn't in the SE tax business. But if you have employees other than yourself (and spouse) and don't collect payroll taxes, the IRS will definitely go after you. They have closed businesses over the payroll tax issue. Just some info that I thought I'd share.
