A few quick questions, then a plain recommendation and a fixed monthly fee in writing. About two minutes. No monthly tie in.

  • Salary and dividends checked
  • Payment on account explained

Your return is personal, while much of the answer sits inside the company books. We bring both together early, explain what is due and include the return in your limited company package.

One Abacus handles directors’ personal tax returns for small limited companies from its two-person Brixton practice. The work sits inside one fixed monthly fee agreed in writing, and the accountant preparing it answers the phone.

What changes when the return is done early

01

Know what belongs on the return

Salary, dividends and income outside the company are checked together.

02

Prepare for the amount due

Your expected bill and any payment on account are explained before January.

03

Put the deadline with us

We prepare and file the return as part of your limited company package.

Where a director’s tax bill starts growing unseen

The surprise usually begins months before the return is filed.

  • Dividends

    “I took dividends all year, then January arrived before anyone had told me what I would owe.”

    The withdrawals were known, but the personal tax had not been calculated early enough to prepare.

  • Salary

    “I assumed payroll covered my personal tax, so I left the return until the deadline was close.”

    Payroll covered the salary. The return still needed dividends and other taxable income.

  • Tax bill

    “I forgot the income outside my company and the amount due changed when there was little time to plan.”

    Adding outside income late can change the calculation and any payment on account.

  • Sorted

    What changes once company and personal income are checked together

    Salary and dividends are matched to the company books. Other income is added before the calculation is final. Any payment on account is explained while there is still time to prepare.

What clients say

One Abacus was recommended to me by several friends and I truly owe them a huge favour as this company has been exemplary! As a new limited company myself and a novice to the contracting world I have had tons of questions and they have been dealt with promptly, effectively and in an approachable and really helpful manner. I couldn't recommend One Abacus enough!

I am currently using one Abacus for sorting out all my freelance accounts and i have to say everything has been perfect with my accountant. they are normally always available even on the weekends when you need something sorted out really quickly. they have sorting out everything from helping with mortgage and notifying when you to pay your tax. really nice and responsive people to talk to if you have questions.

How the January surprise is removed earlier

The work starts with your company, income and deadlines.

Before day one

Your position is mapped

Ryan asks how the company pays you and what other income needs considering.

Day 30

The company books are ready

FreeAgent or Xero is checked so salary and dividends can be traced.

Day 60

The likely bill is discussed

Your income is brought together and any payment on account is explained.

Day 90

The return has a plan

Responsibility, timing and the information still needed are agreed.

When another route may suit you better

We may not be right if you only want a self-filed return checked or signed off.

We do not take on charities, CICs or construction and CIS-led businesses.

We may not be right if taxes remain unpaid and advice will not be followed.

We provide accountancy rather than daily personal administration.

Answer a few quick questions and we will tell you plainly whether there is a fit.

Questions directors ask before January arrives

Is Self assessment for directors included in the monthly fee?

Yes. For limited company clients, the director’s return sits inside one fixed monthly fee alongside payroll, VAT returns, year-end accounts, corporation tax and the confirmation statement. FreeAgent or Xero and the conversations during the year are included too. The full scope is agreed in writing before any work starts.

Can you prepare my return if I already have an accountant?

We first establish who prepares the company accounts and who holds the information needed for your personal return. The responsibilities must be agreed so salary and dividends match the company books. One Abacus only signs off work it has prepared itself, so Ryan will explain what can be taken on after reviewing your position.

Do I have to move from my current accounting software?

A move is not assumed before we understand your set-up. One Abacus works with FreeAgent and Xero, which are included in the monthly package, configured and shown to you. Ryan will check how your company books are currently kept and explain whether a change is needed before anything is moved.

What happens with my current accountant if I switch?

You do not need to wait until the company year end. Once you have agreed the work and fixed monthly fee, One Abacus contacts your current accountant for the handover information. We then check the next company and personal deadlines, set up the software where needed and tell you what remains outstanding.

Why can a payment on account make my January tax bill larger?

A payment on account is an advance payment towards a later tax bill. It can become due alongside the balance for the year just finished, which makes the January amount larger than the tax for that year alone. We calculate whether it applies and explain the amount before the filing deadline.

Does Self assessment for directors apply to every company director?

Being a company director does not automatically mean a return is required. You may need one if HMRC asks for it or your income and circumstances require reporting, including some dividend or untaxed income. Ryan checks the position rather than assuming, then explains what HMRC expects from you that year.
