Frequently asked questions

What tax deductions can I claim as a UK freelancer?

As a self-employed freelancer you can claim HMRC-allowable expenses including home office costs, professional subscriptions, equipment, software, travel on business, accountancy fees, and more. The exact list depends on your profession and employment structure.

When do I need to register for VAT in the UK?

You must register for VAT when your rolling 12-month turnover exceeds £90,000 (2025/26 threshold). Registration must be completed within 30 days of the month in which you breached the threshold.

How is the FFCC Tax Deduction Finder different from HMRC guidance?

HMRC guidance is comprehensive but generic. FFCC uses Claude AI to apply the rules specifically to your profession and circumstances, returning a categorised list with direct HMRC citations.

Is my financial data stored securely?

Yes. Your data is stored in Supabase Postgres with Row-Level Security — only you can access your data. API keys never reach your browser. We never sell or share personal data.

What is Class 4 National Insurance and do I have to pay it?

Class 4 NI is paid by self-employed people on profits above £12,570. In 2025/26 the rate is 6% between £12,570 and £50,270, and 2% above. FFCC's profit calculator accounts for this automatically.

Can I use FFCC with both PAYE employment and a side income?

Yes — the Side-Hustle Profit Calculator specifically handles the tax band impact of primary employment income on your side income, which is a common scenario for millions of UK workers.

How does the late payment interest calculator work?

Under the Late Payment of Commercial Debts (Interest) Act 1998, you can charge 8% above the Bank of England base rate on overdue invoices from business clients. FFCC calculates the exact amount and generates a compliant demand letter.

What is a SIPP and why should I use one as a freelancer?

A Self-Invested Personal Pension (SIPP) is the most tax-efficient way for self-employed people to save for retirement. Contributions receive tax relief at your marginal rate — a 40% taxpayer pays just £60 for every £100 contributed.
