Selling BTL owned through Ltd company - working out the 'profit'...

solidpro

Hi
We setup a Ltd company about 5 years ago and bought a flat for £162,500 as an investment. We're probably going to sell it this summer and use the proceeds to invest elsewhere. Assuming it sells for more than £162,500...
Am I right in thinking CGT doesn't apply to selling a property through a company - because you pay CT on any profits of a Ltd company anyway?
Also, when calculating the profit I believe there are a number of costs which can be added to the outright purchase price of the property - such as replacing a carpet like-for-like, or a boiler like for like. But these potentially have already reduced Corporation Tax when they  were 'expensed' as they were justified expenses which came out of the company - so are these not included in reducing the taxed 'profit' from the sale?
What about the legal costs in buying, selling and arranging company mortgages over the years?

Finally, we haven't, but let's say you improved a property with a better kitchen or nicer floors and invested £20,000 in it through the company coffers and then the place sells for £20k more than you bought it - does this have to be factored in at any point?

I'm probably overthinking it and our accountant would advise but I'm wondering what we're going to deal with when the sale does one day go through...

Thanks

The company pays corporation tax on its profit.

You will pay income tax if you then pay that money to yourself as a dividend (no deductions).

You can deduct capital improvement expenses and the direct cost of buying and selling (legal fees, estate agent fees, etc).  You cannot deduct any expenses you have already had against revenue.  Mortgage arrangement should already have been accounted for.
You will also get indexation allowance up to Dec 2017 ...
