The UK Tax Landscape for New Founders

Most UK startups encounter Corporation Tax, VAT, PAYE for employees, and sometimes Self Assessment for founders. Understanding how these interact, and where your business actually fits today, prevents duplication, missed reliefs, and unnecessary administrative stress.

Choosing a Structure and What It Means for Tax

Sole traders pay Income Tax and National Insurance on profits; limited companies pay Corporation Tax on company profits, while owners are taxed on what they draw; LLPs are generally transparent. Compare risk, admin effort, and funding plans before deciding.

Registering with HMRC and Staying Compliant

Incorporated? Register for Corporation Tax after you start trading. Hiring? Set up PAYE before first payroll. Approaching the VAT threshold? Prepare early, even if you plan to register voluntarily. Keep your Government Gateway details accessible and secure.

Registering with HMRC and Staying Compliant

Note the big ones: Corporation Tax returns typically due within 12 months of period end; payment often due nine months and one day after. Companies House accounts have their own deadline, and Self Assessment online filing is usually by 31 January.

VAT: Register, Reclaim, or Wait?

Monitor the rolling 12‑month turnover threshold, currently set at £90,000. Voluntary registration can help reclaim input VAT, especially with upfront costs. But if most customers are consumers, consider whether VAT will dampen price competitiveness.

VAT: Register, Reclaim, or Wait?

Explore the Flat Rate Scheme for simplicity, Cash Accounting to pay VAT when customers pay you, or the standard method for detailed recovery. Your margins, debtor days, and sector affect which choice supports cash flow best.

Payroll, Contractors, and Off‑Payroll Working (IR35)

Register as an employer, run payroll under Real Time Information, and issue payslips promptly. Track holiday pay, pensions, and statutory payments. Consistent processes build trust with your team and reduce firefighting at month‑end.

Funding and Investor Tax Reliefs
