In Robert Kiyosaki's "Rich Dad, Poor Dad" he talks about building a corporation and doing transaction through it instead of doing them yourself, directly. There seems to be a lot of advantages in doing this like paying less taxes and reduced liability. This seems to be a wonderful idea but I don't understand what are the disadvantages.
Can anyone explain why creating a corporation can be a bad practice?
Creating a corporation is not necessarily less taxes. In fact, you'll face the problem of double taxation, and since you must pay yourself a reasonable salary, if your corporation doesn't earn much to give you as dividend after the salary, and/or your tax bracket is low, you'll in fact may end up paying more taxes. Also there's a lot of bureaucracy involved in managing a corporation.
Liability on the other hand is important, and what's more important - is asset separation and limiting the liability to the corporation assets, keeping your personal assets safe. To achieve that, you don't have to create a corporation, but you can create a Limited Liability Company (LLC). LLC are disregarded entities for tax purposes (i.e.: you won't have to pay taxes twice, only once as a sole proprietor/partner), but provide the liability limitation and asset separation. LLC's are much less formal, and require much less paperwork reducing the risk of corporate veil piercing because of non-compliance.
I myself decided to manage my investments through LLC's for that very reason (asset separation).
Compared with a Sole Proprietorship, the main disadvantages of an S-Corporation or an LLC are that it adds a lot of management overhead (time, and possibly money if you don't do it all yourself), and there are fees you must pay to incorporate, as well as additional yearly maintenance fees which vary by state. You should be able to weigh the tax savings and liability protection against the extra costs and hassle, and see which way the scales tip. As a rule of thumb, the bigger your business gets or the more income you make, the more attractive incorporating becomes.
Note there are some additional taxes that certain jurisdictions impose on business income. For example, IL and CA charge 1.5% tax, NY is less, but NYC is 8.85%! In NYC specifically, you could actually end up paying slightly more tax as an S-Corp than you would as a Sole Proprietorship. In most places though, the nominal local taxes will still be less than the FICA taxes you could potentially save.
