Personal participants pay advance tax for each period as soon as the income is received and will be sent deposit forms for these payments four times a year.
The tax office will determine how much tax must be paid based on last year's surplus.
To ensure that personal participants in new limited companies receive the appropriate forms, they must tell the tax office about the business and state the surplus (or deficit!) they expect to achieve during the first year.
Applications to amend the advance tax you pay can be submitted via this application form.
