Have you outgrown your accountant? 7 signs it's time for more

Most businesses don't fall out with their accountant. They just grow past them. The accountant who was perfect when you were a sole trader filing one tax return a year can be the wrong fit when you have staff, a VAT number, a bank loan and a plan to double turnover.

Here are the signs we see most often in UK founders and owner-managers, and what to do about each one. If you are not sure whether you need an accountant at all, start with [do I need an accountant?](/do-i-need-an-accountant)

If the only contact is a reminder to send your records before the year-end deadline, you have a compliance service, not an adviser. That is fine for a very small business. It stops being fine once decisions you make during the year (pricing, hiring, taking on a lease) change your tax bill and your cash.

A limited company has to file its accounts with Companies House within 9 months of its year end, pay Corporation Tax 9 months and 1 day after the end of its accounting period (for most small companies), and file its Company Tax Return within 12 months ([GOV.UK: annual accounts](https://www.gov.uk/prepare-file-annual-accounts-for-limited-company), [GOV.UK: pay Corporation Tax](https://www.gov.uk/pay-corporation-tax), [GOV.UK: Company Tax Returns](https://www.gov.uk/company-tax-returns)). By the time those deadlines arrive, the year is long gone. Tax planning done after the year end is mostly tax reporting.

Ask yourself: do you know whether last month made money? If the honest answer is "I'll find out when the accounts are done", you are steering by looking in the rear-view mirror.

A growing business needs monthly figures: a profit and loss, a balance sheet and a cash position, ideally within a couple of weeks of the month end. If you're not sure what to look for once you have them, our guide on [how to read monthly management accounts](/how-to-read-management-accounts) walks through it.

Profit and cash are not the same thing. Customers paying late, stock sitting on shelves, VAT and Corporation Tax bills landing at once: all of these can leave a profitable business struggling to pay wages.

An accountant who only prepares year-end accounts won't usually see this coming. What you need is a rolling cash flow forecast, reviewed every month, so you can see the pinch points weeks ahead rather than on the day.

A good accountant asks awkward questions. Why have margins dropped? Why is this customer always 60 days late? Why are subscriptions up 30%? If your accountant processes what you send and never asks why, the numbers are being recorded, not managed.

Cloud software such as Xero links to your bank, captures receipts and lets you and your accountant see the same figures in real time. If your accountant still works from spreadsheets you send at year end, every question takes a round trip and every figure is out of date.

There is also a deadline coming for many owners. Sole traders and landlords with qualifying income over £50,000 in 2024 to 2025 should have started using Making Tax Digital for Income Tax from 6 April 2026. The threshold falls to £30,000 from 6 April 2027 and £20,000 from 6 April 2028 ([GOV.UK](https://www.gov.uk/guidance/check-if-youre-eligible-for-making-tax-digital-for-income-tax)). If your accountant hasn't raised it, that tells you something.

Raising investment, taking on a loan, buying a competitor or preparing to sell all need clean books, credible forecasts and someone who has been through it before. Lenders and investors will ask for management accounts, a forecast and an explanation of your numbers. If your accountant isn't set up to help with that, you'll end up scrambling at exactly the wrong moment.

If you, or a co-founder, are reconciling the bank at 10pm, chasing invoices and running payroll, that is time not spent on customers, product or people. At some point the cost of your own time is higher than the cost of handing it over.

You don't necessarily need to move. Start by asking your current accountant for three things:

- Monthly management accounts within a set number of days of each month end - A 13-week or 12-month cash flow forecast, updated monthly - A short meeting before your year end to look at tax and decisions, not after it

If they can't or won't offer that, it's worth looking at a firm that provides a [complete finance function](/finance-function): bookkeeping, management accounts, tax and finance director support under one roof. Our guide to [what a finance function is](/what-is-a-finance-function) explains what that covers and how outsourced compares with hiring in-house.

Switching is simpler than most people think, and you can do it at any point in the year. Our guide on [switching accountants mid-year](/switching-accountants) covers professional clearance, HMRC authorisation and what to hand over.
