I bought a house, business expense?
So I do day trading at home - it uses to be an apartment but it was a good year and I bought a house outright.
Can I deduct the space I utilize in my home as a business expense on next year's taxes?
Also do I need a business license to be able to claim business expenses?

Hi John - Congratulations on the good year! ;^)
If I remember right, you can deduct an amount of the expenses based on the size of office space compared to the whole house. For example, if you exclusively use one 10' x 15' bedroom (150 sq ft) for your day trading, and the whole house is 2,000 sq ft, then the percentage is 150/2000 = 7.5%.
But if you purchased outright, does this mean you have no mortgage? If so, then you can't deduct the mortgage interest, but you can deduct a portion of property tax.
And you will have some other expenses such as Internet and maybe mobile phone costs - but you will need to separate out "personal use" vs. business use. Plus, you'll have to see if there were any fees the brokerage house charged you that can be used to reduce the capital gains from the trading profits.
As others who respond here will probably say, you should contact a good CPA who is very familiar with day traders and home office business expense. There are a lot of "rules" that sometimes change every year, so your CPA/tax guy needs to be current in his/her knowledge about this area.
Lastly, I don't think you'll need a business license, but you should check with your local city and county offices on their rules. As a "sole proprietor" you end end up paying self-employment taxes because you're both an employer and employee. If you set up an LLC, you might be able to save in some areas, but pay in others (for example, here in California, we get to pay $800 a year just for the LLC registration, regardless if any profit was made). Again, talk to the tax pro.
Hope this helps . . .
