Oct 28, 2025 | Article

Why Year‑End Planning Matters

Planning ahead for the end of your financial year is more than an administrative exercise. It ensures your business remains compliant with regulations, avoids penalties and late‑filing fees, and provides clarity on cash‑flow needs. Marwick & Company has spent more than 50 years delivering personalised auditing, accounting and financial management services. Our long‑standing commitment to understanding each client’s financial objectives underscores the value of proactive planning.

Mark these dates in your calendar and ensure the supporting documentation is ready well in advance.

Practical Year‑End Planning Tips

Thoughtful preparation can streamline the year‑end process and position your business for future growth. Consider the following actions:

  • Keep accurate records – Maintain an organised trail of invoices, receipts and bank statements. This makes it easier to reconcile accounts and substantiate deductions.
  • Reassess your tax strategy – An accountant’s year‑end tips include reinvesting retirement annuity tax refunds, using Employment Tax Incentives (ETI) and taking advantage of tax‑free savings accounts (An accountant’s top tips for Tax Year-End | Sage Advice South …). Review your deductions and exemptions to optimise your tax liability.
  • Check provisional payments – Review your estimated taxable income to ensure your first and second provisional tax payments are accurate. Under‑estimating can lead to penalties, while over‑estimating can strain cash flow.
  • Review cash‑flow and budgets – A year‑end review of budgets and cash‑flow projections can reveal funding needs or surplus capital that may be reinvested in the business.
  • Schedule audits and reviews – Early engagement with auditors or reviewers helps identify issues before final statements are due. It also provides management with time to implement recommendations.
