Your Corporation Tax computed properly, every relief claimed, and every deadline tracked so nothing slips.
Corporation Tax in 2026/27 runs at 19% on profits up to £50,000, 25% above £250,000, and an effective 26.5% marginal rate on the band in between. That middle band is where planning earns its keep, because timing, pension contributions and capital allowances genuinely change the bill.
We prepare and file your CT600, calculate the liability correctly, and make sure you claim what you are entitled to: capital allowances and the Annual Investment Allowance, loss relief and carry back, and R&D relief where it genuinely applies. We also track your payment deadline, nine months and one day after your year end, so the money is planned for rather than a surprise.
Payment is due nine months and one day after your accounting year end. The return itself is due twelve months after year end. Different dates, both fined if missed. We track both for every client.
For 2026/27, 19% on profits up to £50,000 and 25% from £250,000, with marginal relief between creating an effective 26.5% rate on that middle slice. Associated companies split those thresholds, which catches groups out.
Legitimately, often yes. Pension contributions, timing of expenditure, capital allowances and correct loss relief all move the number. That planning conversation belongs before your year end, not after it.
