What some of our clients are saying

Sat down with Mark after going self‑employed and was feeling very overwhelmed with the accounts side of things. He was great and immediately put me at ease. Mel was then allocated as my bookkeeper and has also been absolutely brilliant. Life is so much less stressful knowing my accounts are being taken care of and I can focus on finding and completing work. Would highly recommend JSR to anyone.

Review: JSR Management Accountancy Southampton

Do I Need an Accountant for My Limited Company?

While it is not a legal requirement to use an accountant, most limited company directors choose professional accountancy support to help manage Corporation Tax, payroll, bookkeeping, VAT returns and Companies House filings. An experienced accountant can help ensure your business remains compliant while identifying opportunities to improve tax efficiency and support business growth.


When Should I Register for VAT?

You must register for VAT when your taxable turnover exceeds the current VAT registration threshold set by HMRC. Some businesses also choose to register voluntarily before reaching the threshold. At JSR Management, we can advise whether VAT registration is right for your business and help manage your ongoing VAT obligations.


Can I Switch Accountants Easily?

Yes. Switching accountants is usually a straightforward process. We handle the majority of the transition on your behalf, including contacting your previous accountant and obtaining the information needed to continue managing your accounts. Our aim is to make the process as smooth and stress-free as possible.


What Accounting Software Do You Support?

We support a range of cloud accounting platforms including Xero, QuickBooks and Capium. Cloud accounting software allows you to manage your finances more efficiently, access real-time information and stay compliant with HMRC requirements.


When Should I Become a Limited Company?

Many business owners consider becoming a limited company when profits start increasing, they want greater protection for their personal assets, or they are looking for more tax-efficient ways to operate. Every business is different, so seeking professional advice before making the switch is recommended.


What Is the Difference Between a Sole Trader and a Limited Company?

As a sole trader, you and your business are legally the same entity, meaning you are personally responsible for any business debts. A limited company is a separate legal entity that provides greater separation between your personal and business finances. Limited companies may also offer additional tax planning opportunities and increased credibility with customers and suppliers.


What Is the Difference Between a Partnership and a Limited Company?

A partnership is a business structure where two or more individuals share responsibility for running the business and its profits. A limited company is a separate legal entity with its own legal and tax obligations. The most suitable structure will depend on your business goals, tax position and long-term plans.


What Expenses Can I Claim Through a Limited Company That Are Not Available to Sole Traders?

Limited companies may have access to certain tax-efficient benefits and allowances that are not available in the same way to sole traders. These can include director payroll planning, trivial benefits, annual event allowances and certain benefits in kind. Professional advice can help ensure these are used correctly and compliantly.


Why Do I Need a Separate Bank Account for a Limited Company?

A limited company is a separate legal entity, so it should have its own dedicated business bank account. Keeping business and personal finances separate makes bookkeeping easier, improves financial visibility and helps ensure compliance with HMRC and Companies House requirements.


How Do I Run Payroll as a Director?

A limited company is a separate legal entity, so it should have its own dedicated business bank account. Keeping business and personal finances separate makes bookkeeping easier, improves financial visibility and helps ensure compliance with HMRC and Companies House requirements.

Why Does My Business Need a Dedicated Bookkeeper?

Accurate bookkeeping is the foundation of good financial management. A dedicated bookkeeper helps keep your records organised, ensures transactions are recorded correctly, supports VAT and tax compliance, and provides valuable insight into your business performance. This allows business owners to make informed decisions and focus on growth.


What Is the Difference Between a Profit and Loss Statement and a Balance Sheet?

A Profit and Loss Statement shows your business income, expenses and profitability over a specific period. A Balance Sheet provides a snapshot of your business’s financial position at a particular point in time, including assets, liabilities and equity. Both reports are important for understanding the financial health of your business and making informed business decisions.
