Brouhahaha,
I've looked at all of this area over the past year and I must admit that aspects of it still confuse me. The one thing I will say is this. Go and read about Self Administered Retirement Trusts. There are other lighter weight options as well, but the key feature of them is the level of transparency and control you have.
I would look at pensions as being on a spectrum from the fairly standard Hands off Personal Pensions and PRSA's to the fully hands on Forming your own Trust SARTs.
In between there are pensions that give you some control, but not total control.
If you are the director of a company and you will have a reasonable amount of profit in the company over and above the salary you are drawing out then a look at the Hands On Self Administered side of the spectrum is probably best.
To sum up the benefit of a SART. The company pays to set up a trust which you own.
The company pays money into the trust (lodges it in a bank account). The trust of which you are a trustee can then invest the money to try to build up a fund for your retirement.
There is no income tax for money paid by the company into the trust, even though the trust belongs to you, not the company. There is no Income tax, Capital gains tax etc on any assets or income produced within the trust.
All of the Costs associated with setting up the trust, and all of the contributions to the trust are paid by the company thus reducing the taxable profits of the company.
There are certain age restrictions on when you can access the trust, as there is with any Pension.
These guys describe it in more detail and they are very helpful if you give them a call.
