Guides and explainers

Pages about what a term means or how a job is done, rather than tools you fill in. Each one sits alongside the tool it belongs to.

Am I an employee or self-employed?
UK law has three tiers, not two, and the middle one carries paid holiday and minimum wage.
People
Can I claim it as a business expense?
Most costs are part business and part personal, so the answer is a fraction rather than a yes.
Money
Can my employer change my contract?
A contract takes two to make and two to change. What a flexibility clause really allows.
People
Do I need a business bank account?
A sole trader is not legally required to have one. For a company the money is not yours in the first place.
Business
Do I need a CSCS card?
No law requires one, every site does, and the test alone will not get you it.
Training
Do I need a principal designer?
CDM 2015 turns on one thing: more than one contractor. Not value, size or duration.
Safety
Do I need planning permission?
Permitted development limits in England for fences, driveways, sheds and decking.
Property
Do I need to be a registered waste carrier?
Own waste is usually free lower tier. Construction and demolition waste is the exception.
Business
Do I need to file a tax return?
The 1,000 pound line is a turnover test, not a profit test, and it is not the only trigger.
Money
Do I need to register for CIS?
Contractor registration is compulsory, subcontractor registration is optional and costs ten per cent.
Invoices
Do I need to register with the ICO?
Most businesses handling personal data owe an annual fee, sole traders included.

Property
What am I owed when I leave a job?
Notice, holiday, final pay and redundancy are four separate things, plus what can be deducted.
People
