Frequently Asked Questions
Do all self-employed people have to register immediately?
GOV.UK says a sole trader can start trading without registering, but must register for Self Assessment if self-employment income is more than £1,000 in a tax year. Other rules may also apply.
Can THIQAA advise me which business structure is best?
No. We can explain the administrative service we offer, but choosing a business structure can involve legal, tax or accounting considerations that need appropriate professional advice.
Does this service include completing annual tax returns?
Not as part of this registration service. Any separate tax-return or accounting work would need to be agreed separately and within the service scope available.
