Our Services

Our Accounting Services

At O&S Accounting we pride ourselves on offering a full spectrum of accounting services, tailored to meet the diverse needs of every client we work with. Whether you are an individual, a sole trader, a growing small business, or an established limited company, we have the expertise and the resources to manage your financial matters efficiently, accurately, and with the personal touch you would expect from a local independent firm.

01 · VAT Services

VAT made simple, from registration to return

Navigating the complexities of Value Added Tax can be daunting, especially as your business grows or your circumstances change. Our VAT services are designed to simplify the whole process for you, so you can stay compliant without losing sleep over the detail.

  • VAT registration. We guide you through the registration process from start to finish, helping you choose the right scheme for your business and ensuring full compliance with HMRC.
  • VAT returns. Using HMRC approved in house software, or working seamlessly with your preferred system, we accurately prepare and submit your VAT returns on time, every time.
  • VAT consultancy. Whether you need expert advice on VAT planning, day to day compliance, or help resolving a dispute with HMRC, we are on hand to support you with clear, practical guidance.

02 · PAYE Services

Reliable payroll, every single pay run

Managing payroll can be one of the most time consuming tasks for any business owner, and there is very little room for error when it comes to your team. Our PAYE services make sure your payroll processes are efficient, accurate, and fully compliant with HMRC.

  • Payroll processing. Weekly, four weekly, or monthly payroll runs using HMRC approved in house software, or client specific software where preferred.
  • Tax and National Insurance. We calculate and process all employee tax and National Insurance contributions, including statutory pay, pensions, and student loan deductions.
  • Compliance. Real Time Information submissions, P60s, P45s, and year end reporting all handled, so your payroll meets every relevant regulation and deadline.

03 · Self Assessment

A calmer way to handle your tax return

Filing self assessment tax returns can be complex and stressful, especially if your situation involves more than one source of income. We offer a comprehensive self assessment service that takes the pressure off and makes sure every allowance and relief is being used in your favour.

  • Self employed individuals. Accurate, timely preparation and submission of your tax return, with friendly guidance on allowable expenses and record keeping.
  • Property and rental income. All rental income, mortgage interest, and related expenses correctly reported, so landlords stay compliant and tax efficient.
  • Company directors. Managing the particulars of directors’ returns, including dividends, salary, and benefits in kind, and helping you optimise your overall tax position.

04 · Construction Industry Scheme

CIS handled, so you can stay on the tools

For contractors and subcontractors in the construction industry, compliance with CIS regulations is essential, and the penalties for getting it wrong can mount up quickly. Our CIS services keep you on the right side of HMRC and free you up to focus on the work itself.

  • Monthly returns. Preparing and submitting monthly CIS returns using HMRC approved in house software, or your preferred system.
  • Deductions management. Accurately calculating and processing CIS deductions, verifying subcontractors, and issuing payment and deduction statements.
  • Refund claims. Helping limited company subcontractors and individuals reclaim any overpaid CIS tax, so you are not out of pocket.

05 · Corporation Tax

Year end clarity for limited companies

Corporation tax compliance is essential for every limited company, but it should also be an opportunity to look ahead, not just a yearly chore. Our corporation tax services help you meet your obligations while quietly improving your tax position year on year.

  • Tax returns. Preparing and submitting your company corporation tax return (CT600) accurately and on time, with a full review of allowances and reliefs available.
  • Financial statements. Detailed monthly or quarterly management accounts to keep you informed of your performance, alongside statutory year end accounts for Companies House.
  • Tax planning. Strategic, plain English advice to minimise your corporation tax liabilities and maximise your financial efficiency, including dividend planning and capital allowances.

06 · Bookkeeping

Books that are tidy, accurate, and always up to date

Good bookkeeping is the foundation that every other service rests on. We keep your sales, purchases, bank transactions, and reconciliations in good order, so your figures are always ready when you need them, whether for a finance meeting, a tax return, or a quick check on the month so far.

  • Cloud bookkeeping. Making Tax Digital ready software set up the way that suits your business, with bank feeds and automation doing the heavy lifting.
  • Reconciliations. Bank, card, and supplier accounts reviewed and reconciled regularly, so your numbers are reliable and any issues are spotted early.
  • Plain English reporting. Monthly or quarterly figures presented in a way you can actually use, with cashflow tracking and clear commentary alongside the numbers.
