Corporation Tax (CT600)
Corporation Tax returns (CT600)
Accurate CT600 returns and practical tax planning to reduce your company's tax bill legally.
Overview
Corporation Tax (CT600) handled properly, on a fixed fee.
Every UK limited company must file a Corporation Tax return with HMRC each year, even if it made a loss. We prepare your tax computations and CT600, claim the reliefs and allowances you qualify for, and make sure the payment date is clear well in advance.
Because we usually prepare your year-end accounts too, your Corporation Tax return is built from the same accurate figures, and we can advise on the most tax-efficient mix of salary and dividends for directors.
