Tax Planning

Tax planning that happens through the year, not when the deadline lands. We help limited company owners pay what they owe and not a penny more.

If your accountant only talks tax once a year, you're paying more than you need to.


Most tax planning happens too late to matter


Salary versus dividends. Pension contributions. Capital allowances. R&D claims. Marriage allowance. Director's loan timing. None of these decisions work after year end. They have to be made before.


By the time your accounts are being prepared, the tax planning window for that year has already closed. The numbers are baked. The only question left is how much you owe.

Common Questions

  • When in the year should I plan my tax?

    Three months before your year end is the sweet spot. Anything before that and the figures are too rough; anything after and most of the levers are out of reach.

  • Is tax planning the same as tax avoidance?

    No. Tax planning means using the reliefs and allowances Parliament has written into law. Tax avoidance means structuring artificially to escape tax that was clearly intended. We do the first, never the second.

  • Can you reduce a corporation tax bill I've already had?

    Sometimes, yes. Errors get corrected, R&D claims can go back two years, and capital allowances can be re-examined. The first thing we do is look at your last two years to see what's recoverable.

  • How much can good tax planning save me?

    It depends on the business. For a profitable owner-managed limited company, savings of £3,000 to £15,000 a year are typical. The fee is usually a small fraction of that.

  • Do you handle personal tax planning too?

    Yes. We look at your business and your personal position together, since the decisions affect each other. Your self assessment is part of the same conversation.
