Thank you all for the input. Your points have given me a lot to think about. I think it's still worth considering because the reasons think it's a bad idea fall within risk, tax liability, and complexity.
Risk
I may not have been clear, but the house I would be selling to the business is not my home, it's a rental property on a buy to let mortgage that has a long term tenant. So I'm not risking my home.
The risk of the business doing badly and resulting in a repossession is minimal. I don't have staff, or significant suppliers, basically I provide a service, I bill, and I pay myself. If work stops for some reason I just stop paying myself, so the business wouldn't go under. The rental income will cover the mortgage payments- it's v desirable and has never been empty.
Am I missing something here? I suppose the company mortgage might be higher than the one I currently have, but so long as rent covers mortgage and a bit of maintenance it's fine?
Tax liability
Am I right in thinking, if I sell the property to my business, I personally will have to pay capital gains on the profit between when I bought it, and when I sell it to the company?
This might be worth it. Because of my company is paying the mortgage n the property, that money is coming out the company as a business expense, so avoiding 40% personal income, AND bringing down corporation tax liability? This would be for 20th years so quite a saving. Again, I don't think well in numbers or systems, so if I'm not getting it, I'd be glad to know.
Complexity
Yes. It's definitely more complex. But does that means it's a bad idea?
I'd anyone has the time to detail the nuances I'd be keen to know.
Thanks again x
Will look up SIPP now, I don't know what that is.
