@jdisme Firstly set up a meeting with a tax accountant to sort out the tax side and get registered under CIS. The tax accountant should be able to go through what reliefs are claimable and the most efficient way to take earnings out of your company.
As your companies turnover is likely to exceed £30,000 pa you can potentially register for the gross payment scheme once you have at least 12 months of successful trading and being compliant with your tax affairs. Gross payment means all payments would be made without a tax deduction. You do then become solely a completely responsible for paying the correct amount of tax, always put money aside each month for tax if you go down this route.
As you are employed via your own company please check the contract conditions between your company and the companies that have contracted your company. Key things to check are:
- insurance requirements
- Any requirement to provide alternative workers should you not be available
- notification of work / non work, are you contracted to work for set period or "as required".
As a crane supervisor please, please check that you are covered by the main contractors insurance when supervising lifting operations, this should be stated in contract. If not get your own insurance.
