Corporation Tax Payment Planning

Corporation tax payment planning helps you stay in control of your company’s tax bill by forecasting what you’ll owe, when it’s due, and how to fund it. Instead of a last-minute scramble, you get a clear schedule and a practical cash flow plan so your corporation tax payment is predictable and stress-free.

More information

What corporation tax payment planning covers

This service turns your corporation tax into a planned outgoing, not an unpleasant surprise. It typically includes:

  • Confirming the relevant payment deadline for your company and accounting period
  • Estimating your corporation tax based on up-to-date bookkeeping and management figures
  • Setting a simple set-aside plan (monthly or per invoice) to build the funds as you trade
  • Cash flow planning so tax payments do not clash with VAT, payroll, or major business costs
  • Flagging common factors that move the bill (profit changes, director pay, dividends, capital spend)
  • Reviewing estimates through the year and updating the plan as your numbers change
  • Reminders and a clear payment plan so you know what to do and when

Who this is for

Corporation tax payment planning is most useful if:

  • You run an owner-managed limited company and want predictable tax outgoings
  • It’s your first year trading and you are unsure when corporation tax is actually due
  • Profits are growing, seasonal, or lumpy, making it hard to judge what to keep back
  • You take dividends and want to understand how they interact with company profits and reserves
  • You want to avoid late payment interest and protect working capital

How the service is delivered

The process is straightforward and built around real numbers:

  1. We review your latest bookkeeping and any key changes coming up (pricing, costs, hires, investment).
  2. We calculate an estimated corporation tax position for the year so far and for the expected year-end.
  3. We agree a set-aside approach that fits your cash flow, such as a monthly transfer to a tax pot.
  4. We refresh the estimate at agreed points during the year, so the plan stays accurate.

After the plan is in place

You get ongoing clarity, not a one-off calculation. As your results change, the estimate and set-aside amount can be updated so you stay prepared for the payment date. When year-end accounts and the corporation tax return are finalised, the plan helps ensure the funds are already available.

Frequently Asked Questions

When is corporation tax due to be paid?
For many small UK limited companies, corporation tax is due 9 months and 1 day after the end of the accounting period. Some larger companies may need to pay by instalments, so we confirm the rule that applies to you.
How accurate is a corporation tax estimate during the year?
An estimate is only as good as the bookkeeping and the assumptions used. With up-to-date records and regular check-ins, you can get a reliable range and adjust your set-aside as profits move.
What information do you need to create a payment plan?
We typically need your current bookkeeping, your year-end date, and details of any significant changes coming up (large purchases, new staff, pay and dividends). If records are behind, we will prioritise getting them up to date first.
Does this service include filing the corporation tax return?
Payment planning focuses on forecasting and cash flow so you are ready to pay on time. If you also need statutory accounts and the CT600 prepared and filed, that can be handled alongside the plan.
What if my profits change significantly before year end?
That is exactly why the plan is reviewed and updated. If profits rise or fall, we revise the estimate and the set-aside amount so you are not over-saving or caught short at payment time.
