How does one treat their personal trading as a business? Do they build a website? Do they buy advertising in the local paper?
You've been here at this forum a very long time. Thus, not sure if you're joking because there's lots of threads here about such.
Seriously, pretend you're starting a
business as a self-employed trader...what's the first thing you're going to do ? See your tax accountant and have a long discussion so that you'll know what you need to do before the next tax report year involving ownership structures (e.g. sole proprietorship, LLC, S corporation and other alternatives). Also, will not hurt to setup an in person appointment with a IRS tax representative (that's what they are called in the U.S.) about self-employment and different types of trader status you may need to declare.
Next, go see you bank representative about what you need to do to setup a business account but only after advice from you tax accountant and IRS tax rep.
Just as important, find a friend or relative that's a self-employed business owner for some private discussions about such even if they have employees. Also, if you already have a job with typical benefits...you don't have to worry about that stuff like health/dental insurance unless you plan on quitting your job. Yet, if you don't have a job and you're a profitable trader with a decent income...make sure you discuss those things (e.g. health/dental insurance, self-employment pension plan and many other stuff) with your tax accountant and then insurance companies that cater to self-employed citizens...it ain't cheap.
P.S. What about traders that are not profitable or have a down year ? A trader that's not profitable without the proper declared trader status with their government...will not be able to deduct many things associated with the cost of trading. My point, don't be stupid and think you can be a trader while not letting the tax folks know you really are a trader.
Today, there's lots of public documentation about this at the government tax office. Simply, it ain't like the 1990's when people were running around without their heads when it came to a simple market to market (m2m) declaration. There are online tax services that specializes in that stuff for traders these days if your tax accountant is not schooled enough about traders/taxes.
This is how you should start to treat your
trading like a business and it has nothing to do with trade signal strategies or starting a website.
P.S.S. I remember many years ago when I was single when I first met a particular girlfriend's parents. The parents owned their own business and very successful with +30 employees. I remember the first question they asked when I told them I was a private trader...they asked what was my "business ownership tax structure" and what company I was with for private insurance.
They didn't care if I was a trader, mechanic, landscaper, interior designer or flipping real estate properties. They just wanted to see if I was serious about whatever I was doing as if it was a
business and what
plan B I had in place.
