If you run a limited company, filing your Corporation Tax Return (CT600) is a legal requirement — and getting it wrong or filing late can lead to penalties.

At Straight Ledger Bookkeeping & Accountancy, we make sure your return is calculated correctly, submitted on time, and that you claim all allowable expenses and reliefs to reduce your tax bill wherever possible.

Whether you're a new company filing for the first time, or an established business looking for better support — we’re here to take care of it, clearly and professionally.

What’s Included?

Our Corporation Tax service covers everything required to keep your company compliant with HMRC:

• 📄 Preparation and submission of your Corporation Tax Return (CT600)
• 📊 Accurate calculation of your company’s taxable profits
• 🧾 Identifying all allowable expenses, capital allowances, and reliefs
• 🔄 Linking your tax return to your year-end accounts
• 📤 Online filing direct to HMRC
• 📆 Deadline management and reminders
• 💬 Tax-saving tips and proactive advice for the year ahead

We can also handle corrections to previous returns, or step in if you've fallen behind and need to catch up.

When Is It Due?

You must file your CT600 within 12 months of your company’s year-end — but payment of your Corporation Tax is due within 9 months and 1 day after your accounting period ends.

We’ll keep you ahead of these deadlines so there are no surprises, interest charges, or penalties.

Who Needs This Service?

All limited companies must file a Corporation Tax return — even if they made no profit or owe no tax. We work with:

• Owner-managed companies
• Contractors & consultants
• Trades & service-based companies
• Online and retail businesses
• Growing teams and first-time directors

If you're unsure about your obligations or think your last accountant may have missed something — we’ll review your records and give you clear, honest guidance.

Fixed Monthly Pricing That Works for You

Our Corporation Tax services are often part of a full monthly accountancy package, where we agree a custom annual fee, then divide that into affordable monthly payments.

No large one-off bills. Just clear, manageable costs throughout the year.
