Hi and welcome to Just Answer!
When you purchase a house - your purchase price is the basis.
When flipping a house - the basis is adjusted - you add all purchase, sale and repair costs to the basis.
Your gain will be (selling price) - (adjusted basis).
Among others - you will deduct:
-recording fees with local authorities
-real estate fees
Let me know if you need any help or clarification.
Yes - that is correct.
if real properties are involved - a foreign person (the transferor) is subject to the Foreign Investment in Real Property Tax Act of 1980 (FIRPTA) income tax withholding. Generally settlement officers are required to withhold 10% of the amount realized. Please see some information here - http://www.irs.gov/businesses/small/international/article/0,,id=105000,00.html
If withholding is more than your tax liability - you would need to file a tax return and claim a refund.
Please be aware that 10% FIRPTA income tax withholding is not applied to the sale price - but only to the amount payable to you.
Your expenses are $260,000 plus $70,000 = $330,000
if selling fro $425,000 - your gain is $95,000.
If that is occasional sale - and you are not in business of flipping houses - the gain will be added to your other taxable income and you will pay income tax based on your total income, filing status, deduction, etc - see tax rate schedule on last page in this publication - www.irs.gov/pub/irs-pdf/i1040tt.pdf
If you are single and that is your only income - your estimated federal income tax liability is $17,600.
If you held the property more than a year - the gain might be treated as long term capital gain taxable at reduced rate - not more than 15% - and your max tax would be $14,250
If you are in business of flipping houses - that income will be subject of self-employment taxes IN ADDITIONAL to income tax. The self-employment tax rate is 13.3% (for 2011) - so your estimated additional self-employment tax will be $12635. In this case your total tax would be estimated as $17,600+$12635=~$30,000
Please be aware these are very raw estimates. To determine your exact tax liability the tax return should be prepared.
For nonresident aliens - the issue is that without a proper authorization you are not eligible to work or be self-employed.
If you are an investor and occasionally purchase a house for resale and all renovation work is done by others - you have a capital gain on the sale and if the property is held more than a year - you will only pay federal income taxes on the capital gain.
That would be the most beneficial from tax prospective.
If you are in business of flipping houses - your only choice to do that legally without a work authorization permit would be to create C-corporation which would be a separate legal entity. C-corporation will hold properties. purchase materials and pay for renovations to subcontractors.
There is no strict difference and all depends of circumstances.
Generally - number of properties and time you hold them before selling would be used as primary criteria.
If you re-sell one property in two years and hold it at least for a year - most likely - you are an investor.
If you re-sell three properties during the year and held them less than six months - most likely - you are in business.
That is not correct - you may purchase the house for your family and renovate it by yourself - but you may not receive a compensation for your work if you do not have a proper work authorization.
In additional for some type of work - you do have to hire a licensed contractor - for instance for electrical wiring. You need to verify your state and city building code which works require that.
From tax prospective - all these would not matter - as long as you report all your income and pay all taxes - the IRS would not object.
Above you wrote - that house I'm buying is for my family , i cannot renovate it myself - that means you purchase a personal property and renovate it for yourself or your family.
Now you are telling - I'm selling the house after 6 months of the original purchase - that means you have a profit motive and your purchase the property either as an investment or a business.
If that is the only property you sell during theyear - you might be able to treat it as an investment - and will pay only income taxes on capital gain.
If you are selling several properties - that is self-employment activity and in additional to income taxes - you will be liable for self-employment taxes. Having an LLC doesn't change your tax liability - but will be an additional evidance that you are in business.
Then - you are asking - i will pay 10% withholding tax and that's it ?
Withholding is applied at the time of payment - that is not your tax liability. The tax liability is determined when you file your tax return. The purpose of withholding - to cover your possible tax liability. If the amount withheld is more than your tax liability - you will claim a refund. If less - you will pay additional taxes.
