Frequently Asked Questions
Do I need to register as self-employed if I freelance part-time?
If you earn more than £1,000 from self-employment in a tax year, you must register with HMRC and file a Self Assessment return. Even below that threshold, keeping proper invoices is good practice and makes things easier if your side hustle grows.
Can I use Experi alongside my full-time job?
Absolutely. Experi is designed for people who don't have hours to spend on admin. Create invoices on your phone, send them instantly, and let automatic reminders chase payments for you — all outside working hours.
Do I need to charge VAT on my side hustle income?
You only need to register for VAT if your taxable turnover exceeds £90,000 in a 12-month period. Most part-time freelancers are well below this threshold, so you likely won't need to charge VAT.
How do I keep my freelance income separate from my salary?
We recommend a separate bank account for freelance income — it makes bookkeeping and tax returns much simpler. Include those bank details on your Experi invoices so client payments go straight to your business account.
