After running into trouble with the taxman just a year or so into my first business, I hired two accountants, one after the other, who managed to dig me in even deeper. I bit the bullet and brought in the biggest accountancy firm in Ireland at the time, BDO Simpson Xavier. It cost me a small fortune, but I never had to face another taxman personally again.
When it comes to those buggers, you want the biggest, beefiest buffer you can find. In the end, it saved me fortunes and a lot of stress.
