Tax Credits & Deductions Review (Ltd Companies)

A Tax Credits & Deductions Review checks your limited company’s records during the accounts process to identify legitimate reliefs, allowances, and deductible costs you may have missed. The aim is simple: reduce your corporation tax bill where possible while keeping your accounts and filings accurate, consistent, and properly supported.

More information

What the review covers

We build this review into the year end accounts work, so it is based on what is actually in your books and what can be evidenced.

  • Review of expense categories to confirm what is allowable and what should be treated differently
  • Identification of missing deductions, accruals, or prepayments that affect taxable profit
  • Capital allowances review for qualifying assets (equipment, tools, IT, software, and some vehicles)
  • Consideration of relevant reliefs such as R&D tax relief where the activity and records support a claim
  • Checks on director and employee benefits and reimbursements to ensure the right tax treatment
  • Loss relief considerations where applicable, and how losses are carried forward
  • Clear notes on what has been claimed and what evidence should be retained

When this service is most useful

This review is a strong fit for owner-managed limited companies where costs are varied, asset purchases are common, or the business is changing.

  • You have grown quickly and want confidence nothing is being missed
  • You have bought equipment, computers, tools, or started using new software
  • You incur mixed business and personal costs and want clear boundaries
  • You think you might qualify for R&D tax relief but are unsure what counts
  • Your bookkeeping is up to date, but you want a second set of eyes before filing

How the review is delivered

The review is completed alongside the year end accounts and corporation tax work.

  1. We review your bookkeeping, ledgers, and supporting documents (or exports if needed).
  2. We ask targeted questions to clarify the nature of specific costs or projects.
  3. We propose any adjustments needed for correct tax treatment and agree these with you.
  4. We reflect the final position in your statutory accounts and corporation tax return.

What you receive after the review

You get practical, plain-English outputs you can use year after year.

  • A summary of key deductions and reliefs applied, and why
  • A list of any items treated as disallowable, with the reasoning
  • An evidence checklist to help you stay audit-ready
  • Recommendations to improve how expenses are recorded going forward, so future reviews are quicker and more robust

Frequently Asked Questions

What counts as an allowable deduction for a limited company?
In most cases, costs must be incurred wholly and exclusively for business purposes to be deductible. We review how items are recorded and whether they need to be reclassified, restricted, or supported with better evidence.
Can you check whether we qualify for R&D tax relief?
Yes, we can assess whether your work is likely to qualify and what documentation would be needed to support a claim. If it is suitable, we guide you on the next steps to prepare a robust submission.
Do you need access to my accounting software?
Access helps us review the detail efficiently and reduces back-and-forth questions. If that is not possible, we can often work from reports and exports, as long as they are complete.
Will the review change my year-end accounts or Corporation Tax return?
It can, if we identify missing deductions, capital allowances, or items that need different treatment. Any adjustments are discussed with you before we finalise the accounts and submit the return.
How can I improve deductions and record-keeping going forward?
We will highlight practical changes such as better categories, clearer descriptions, and what evidence to keep. Many clients also benefit from regular check-ins so issues are fixed during the year, not at year end.
