What's the appropriate way to signify an S-Corp?
"S-Corp is a corporation. I.e.: you add a ""Inc."" or ""Corp."" to the name or something of that kind. ""S"" denotes a specific tax treatment which may change during the lifetime of the corporation. It doesn't refer to a legal status." "Subchapter S Corporations are a special type of corporation; the difference is how they are taxed, not how they relate to their vendors or customers.  As a result, they are named the same way as any other corporation. The rules on names of corporations vary by state.  ""Corporation"" and ""Incorporated"" (and their abbreviations) are allowed by every state, but some states allow other names as well.  The Wikipedia article ""Types of business entity"" lists an overview of corporation naming rules for each state. The S-Corp that I work for has ""Inc."" at the end of its name."
Yes, you should be able to deduct at least some of these expenses.  For expense incurred before you started the business: What Are Deductible Startup Costs? The IRS defines “startup costs” as deductible capital expenses that are used to pay for: 1) The cost of “investigating the creation or acquisition of an active trade or business.” This includes costs incurred for surveying markets, product analysis, labor supply, visiting potential business locations and similar expenditures. 2) The cost of getting a business ready to operate (before you open your doors or start generating income). These include employee training and wages, consultant fees, advertising, and travel costs associated with finding suppliers, distributors, and customers. These expenses can only be claimed if your research and preparation ends with the formation of a successful business. The IRS has more information on how to claim the expenses if you don’t go into business. https://www.sba.gov/blogs/startup-cost-tax-deductions-how-write-expense-starting-your-business Once your business is underway, you can deduct expenses, but the exact details depend on how you organized.  If you're a sole proprietor for tax purposes, then you'll deduct them on Schedule C of your Form 1040 on your personal tax.  If you are a partnership, C-Corp, or S-Corp, they will be accounted at the business level and either passed on to you on a Schedule K (partnership and S-Corp) or deducted directly by the company (C-Corp). In any case, you will need good records that justify your expenses as business related. It might be well worth at least an initial meeting with a CPA to make sure that you get started on the right foot. I wouldn't stress out too much about what you call the category. As long as it makes sense to you and your tax accountant it should be fine. Besides, it's usually pretty easy to rename a category in the future. Just for reference, my accountant set up my categories (also for S-Corp) like this (though this was 8 years ago but I still use them today): Good answer.  I set up an S-Corp on my own, but I intend to transfer our intellectual property to an LLC at a later date.  I would say hiring an attorney to draft an operating agreement is a must and worth the expense. "There are no dividends from S-Corp. There are distributions. Big difference. S-Corps fill form 1120S and schedule K-1 per shareholder. In the schedule all the income of your S-Corp will be assigned to various categories that you will later copy to your personal tax return as your personal income. It is not dividend income. The reason people prefer to take distributions from their S-Corps instead of salary is because you don't pay SE taxes on the distributions. That is also the reason why the IRS forces you to pay yourself a reasonable salary. But the tax rate on the income, all of it, is your regular income tax rate, unless the S-Corp income is categorized in a preferred category. The fact that its an S-Corp income doesn't, by itself, allow any preferential treatment. If you're learning the stuff as you go - you should probably get in touch with a tax professional to advise you. All the S-Corp income must be distributed. Its not a matter of ""avoiding paying the tax"", its the matter of ""you must do it"". Not a choice. My answer was not intended or written to be used, and it cannot be used by any taxpayer, for the purpose of avoiding penalties that may be imposed on the taxpayer (circ 230 disclaimer)." Sorry, I got even more confused. I assumed IC referred to equity only. At least under English accounting practice it's the norm to refer only to equity investment as capital in that context. The debt is listed as both an asset (cash or whatever asset the cash has been put towards) and a liability, cancelling it out. That being the case, the number would be the same, no?

Does the corporation need the money for its ongoing business? If so, don't transfer it. If not, feel free. This decision has nothing to do with whether the corporation made money in any particular year. If this activity were to generate let's say 100K of profit, and the   other corporate activities also generate 100K of revenue, are there   any issues tax-wise I need to be concerned about? Yes. Having 25% or more of passive income in 3 consecutive years will invalidate your S-Corp status and you'll revert to C-Corp. Can I deduct normal business expenses from the straddles (which are   taxed as short term capital gains) profit? I don't believe you can. You can deduct investment expenses from the investment income. On your individual tax return it will balance out, but you cannot mix types of income/expense on the corporate return or K-1.
