- You can't use the allowance in a tax year if any of your trading income comes from a company you, or someone connected to you, owns or controls; a partnership where you or someone connected to you is a partner; or your employer, or your spouse's or civil partner's employer.
- You can use the allowance or your expenses, not both.

Is selling my own old things trading?
Usually not. Selling things you made, or bought to sell on, usually is.
Do I need to register?
If your trading income is over £1,000 in the tax year, register for Self Assessment and declare it.
