Your company can buy some amazing computer hardware before taxes. Yet it is a waste of money to be doing that every year. It can buy a top range company phone but the SIMM only contract itsis a taxable benefit. Your personal tax bill will swell to include 40% of the SIMM contract cost. That is a 60% saving over busingbuying a personal contract from your salary, but it doesn't really excite me. In the UK small companies don't get the huge discounts that UK consumers get. For example, you will pay charges for your company bank account and in the UK we are used to getting free personal-banking. IHMO you get hit with a lot of unexpected costs so it really isn't as rosy as people think. YMMV.
Once you take the red pill and see a few tax bills you might suddenly take a very keen interest in tax efficiency. My number one tip is to track the money of every paid invoice and assume the worst possible taxes on that invoice. By overestimating the taxes you will always be able to pay the tax bill and your company bank balance will grow. When it is about six months worth of money to live off thethen start creaming it off into a pension.
The most tax-efficient thing you can do is live off your main job and don’t spend the company money. The company account can then be your “rainy day” account for “life events”. If you ever lose your main job you can take out company money very efficiently. Let's say you lose your job on the last day of the tax year. You can then draw both full personal tax allowance £12.5k and the dividend allowance tax of £2kallowance. That is £14.5k tax-free. You canwill then pay only paying 7.5% tax on the next £36£35.5k. So that is £2.6k of tax on 50k. Then you are laughing and the taxman isn't. You could quit your job and travel around the world doing freelance remote work and really be really winning.
