Self Assessment That Works for You, Not Just for HMRC
Your limited company is an enabler. It exists to fund your lifestyle, goals, and ambitions. Yet most self assessment content treats tax returns as a burden, a box to tick, an obligation to HMRC.
We see it differently.
Your self assessment reflects how well you’ve planned your finances throughout the year. The salary you drew. The dividends you declared. The pension contributions you made. Every decision shapes the tax you pay.
At FD Works, we move the conversation from “what do I owe?” to “how do I want my business to reward me?” We plan your optimal extraction strategy from day one and monitor it quarterly. If a business stands still, it’s going backwards. The same applies to tax planning.
Self assessment becomes a formality because the thinking happened months ago.
Do You Need to File a Self Assessment Tax Return?
If you’re a company director receiving a salary and dividends from your limited company, you almost certainly need to file a self assessment tax return. HMRC requires you to declare all income sources, even if your salary is taxed through PAYE.
Who must file a self assessment tax return
- Company directors receiving salary and dividends (this is you)
- Self-employed individuals earning over £1,000
- Landlords with rental income over £2,500
- High earners over £60,000 claiming Child Benefit
- Anyone with capital gains to report
- Higher-rate taxpayers with significant savings or investment income
Self assessment deadlines and penalties
Two dates matter:
- 31 January — online filing deadline (and payment deadline)
- 31 October — paper filing deadline (rarely used)
Payment on account dates add complexity. Your first payment on account is due 31 January alongside your balancing payment. Your second payment on account is due 31 July.
Late filing triggers immediate penalties:
- £100 fixed penalty — even if you owe nothing
- £10 per day — after 3 months, up to 90 days
- Additional penalties — at 6 and 12 months
Late payment attracts interest immediately, with a 5% surcharge at 30 days, 6 months, and 12 months.
FD Works tracks every deadline. Our clients never face late filing penalties. We file well before January and plan your cash so you’re ready for payment on account dates.
Directors’ Self Assessment: It’s About Planning, Not Just Filing
For limited company directors, self assessment is where personal and business finances meet. What you declare directly reflects decisions made throughout the year.
What directors declare on self assessment
- Salary from your limited company — reported on your P60/P45
- Dividends — declared and paid during the tax year
- Other income — rental, savings interest, capital gains, foreign income
- Allowable reliefs — pension contributions, gift aid donations
- Student loan repayments — Plan 1, 2, 4, or postgraduate
The salary and dividend question
This is the most important tax planning decision you make each year.
Most directors pay themselves a low salary topped up with dividends. Why? National Insurance savings. Dividends don’t attract employer or employee NI, whilst salary does. Dividend tax rates are also lower than income tax rates on equivalent earnings.
For 2025/26, common salary levels are:
- £12,570 — the personal allowance, maximising income tax efficiency
- NI primary threshold — minimising NI whilst building qualifying years
Above your salary, dividends fill the gap:
- £500 tax-free — the dividend allowance (2025/26)
- 8.75% — basic rate dividend tax
- 33.75% — higher rate dividend tax
- 39.35% — additional rate dividend tax
Critical update for 2026/27: Dividend tax rates are rising by 2 percentage points from April 2026. Basic rate moves to 10.75%, higher rate to 35.75%. This makes salary and dividend planning more critical than ever.
But generic advice doesn’t work. Your optimal split depends on your personal circumstances, other income sources, and financial goals. That’s where FD Works comes in.
Tax planning throughout the year
We don’t just file your return. We plan your tax position:

- Quarterly reviews — Adjust your salary and dividend strategy as profits change
- Pension contributions — Reduce taxable income whilst building long-term wealth
- Corporation Tax interaction — Your extraction strategy affects company tax too
- Pre-year-end planning — Maximise allowances before 5 April

Your Business Should Fund Your Ambitions, Not Just Pay Your Tax Bill
Most self assessment content starts with “what do I owe HMRC?” We start with “what do you want?”
Your limited company is a vehicle. It should fund your salary, lifestyle, pension, and long-term goals. The question isn’t how much tax you’ll pay. It’s how to structure your finances so you keep more, stress less, and build wealth.
Start with your goals, not your tax return
- What take-home income do you need to fund your lifestyle?
- What pension contributions support your retirement plans?
- What capital investments or savings goals matter to you?
- How does your extraction strategy affect Corporation Tax?
Reverse-engineer the optimal strategy from your goals, not forwards from HMRC’s requirements.
How FD Works plans your tax position
- Annual tax planning review — set your salary and dividend strategy for the year ahead
- Quarterly Health Checks — monitor progress and adjust as profits change

This is what we mean by embracing the numbers to shape your business. Unlock your ambition through financial clarity, not compliance burden.

Self Assessment Tax Returns: Your Questions Answered
Do company directors need to file a self assessment tax return?
Yes. If you receive a salary and dividends from your limited company, HMRC requires you to declare all income through self assessment. Even if your salary is fully taxed through PAYE, dividends are taxed through self assessment.
FD Works handles director self assessment as part of our monthly service. We plan your salary and dividend strategy throughout the year so there are no surprises when your return is filed.
When is the self assessment deadline?
The online self assessment deadline is 31 January following the end of the tax year. For the 2024/25 tax year, this means filing by 31 January 2026. Paper returns must be filed by 31 October 2025. Payment of any tax owed is also due by 31 January.
Late filing triggers an automatic £100 penalty, escalating to £10 per day after 3 months. FD Works files all returns well before the deadline. Our clients never face late filing penalties.
Is it worth getting an accountant for self assessment?
For company directors with salary and dividends, absolutely. An accountant doesn’t just file your return. They plan your tax position to minimise what you pay legally. The right salary and dividend split, pension contributions, and allowance planning can save thousands annually.
FD Works goes further. We plan your optimal remuneration strategy throughout the year, not just file a return in January. The tax savings from proper planning typically exceed the cost of our service.
How much should a self assessment cost?
Standalone self assessment returns typically cost £200-£500 depending on complexity. However, a standalone return without year-round tax planning misses the biggest opportunity.
FD Works includes director self assessment in monthly service tiers, bundled with bookkeeping, annual accounts, VAT, payroll, and quarterly Health Checks. Contact us for a quote tailored to your business.
What is the most tax-efficient salary for a director?
For 2025/26, common director salary levels are £12,570 (the personal allowance) or the NI primary threshold. The optimal level depends on your personal circumstances, other income, and whether you want to build NI qualifying years.
FD Works models different salary and dividend scenarios using our Salary and Dividend Calculator and recommends the optimal strategy based on your full financial picture.
How are dividends taxed in the UK?
Dividends have a £500 tax-free allowance (2025/26). Above this, basic rate taxpayers pay 8.75%, higher rate 33.75%, and additional rate 39.35%. From April 2026, basic and higher rates rise by 2 percentage points.
This makes salary and dividend planning even more critical. FD Works reviews your remuneration strategy annually and adjusts for rate changes so you always pay the minimum tax legally due.
What records do I need for self assessment?
You need P60 or P45 (salary), dividend vouchers, bank statements, rental income records, pension contribution certificates, and any capital gains documentation. HMRC requires records kept for 5 years after the filing deadline.
FD Works clients have year-round bookkeeping via Xero and Dext. All records are digital, categorised, and audit-ready. No January scramble for paperwork.
Can I reduce my tax bill through self assessment?
Yes, through legitimate tax planning. Pension contributions reduce taxable income. Gift Aid donations extend your basic rate band. Allowable expenses can be claimed. The salary and dividend split itself is the most powerful planning tool for directors.
But these decisions should be planned throughout the year, not discovered at filing time. FD Works integrates self assessment planning with quarterly Health Checks so you take action when it matters.
