TAX RETURN - SELF ASSESMENT
Self-Employed Tax Return & Self Assessment Services
Running your own business brings freedom — but it also means you’re fully responsible for keeping your finances compliant.
If you’re self-employed in the UK, completing your Self Assessment tax return accurately and on time is crucial to avoid penalties and overpayments.
At CIDB Solutions Ltd, we make the process fast, precise, and stress-free. Our digital-first approach allows you to handle your entire self-employed tax submission remotely — securely, efficiently, and at a fraction of the cost charged by traditional firms.
Simplifying Self Assessment for the Self-Employed
Submitting a Self Assessment to HMRC can feel complicated, especially when managing multiple income sources, expenses, or CIS deductions.
Our goal is to take that burden off your shoulders.
We manage your entire Self Assessment process — from gathering income information to reviewing allowable expenses and submitting your final report digitally to HMRC.
You’ll never have to worry about forms, figures, or deadlines again.
Who Needs to File a Self Assessment
You must file a Self Assessment if you’re earning income outside of PAYE. That includes:
Self-employed sole traders earning more than £1,000 per year.
Subcontractors working under the Construction Industry Scheme (CIS).
Freelancers, consultants, and contractors with multiple income streams.
Individuals with rental or side income in addition to PAYE.
We ensure all your income sources are properly declared and your tax return reflects the true financial picture — no errors, no omissions.
Our End-to-End Digital Filing Process
We handle every step of your self-employed tax filing with precision and transparency:
UTR registration and verification.
Digital record collection from your invoices, CIS statements, and bank transactions.
Expense categorisation – identifying deductible costs (travel, tools, office, utilities).
Submission to HMRC through our secure, MTD-compliant system.
Electronic confirmation once HMRC accepts your submission.
Everything is handled remotely through our encrypted client portal — you upload, we manage, and you stay informed in real-time.
Maximising Refunds & Deductions
Most self-employed workers overpay tax every year simply because they don’t claim all eligible deductions.
Our accountants review your full financial history to ensure every allowable cost is used to reduce your taxable profit.
Typical deductible categories include:
Tools and materials used for your work.
Business mileage and vehicle costs.
Rent, phone, and utilities for home-office use.
Insurance, training, and professional memberships.
This detailed review ensures your Self Assessment results in the lowest legal liability.
CIS Reconciliation for Construction Workers
If you work under the Construction Industry Scheme (CIS), your contractors have likely already deducted tax at source.
We specialise in CIS tax reconciliation, making sure those deductions are correctly offset against your income and expenses.
If you’ve overpaid through CIS, we’ll help you reclaim what you’re owed — quickly and efficiently.
Our digital process shortens HMRC turnaround times, meaning your refund reaches your account sooner.

Frequently Asked Questions
What is a Self Assessment Tax Return?
A Self Assessment Tax Return is the system used by HMRC to collect Income Tax from individuals who don’t have it automatically deducted through PAYE. It applies to self-employed individuals, landlords, company directors, and anyone with untaxed income. The return calculates your total income, expenses, and tax due for the financial year.
Who needs to file a Self Assessment Tax Return?
You must file a tax return if you:
Are self-employed or a sole trader
Earn over £1,000 outside of PAYE employment
Receive rental income, dividends, or foreign income
Work under the CIS (Construction Industry Scheme)
Are a director or shareholder of a Limited Company
Or simply need to declare any additional income not taxed automatically
We handle the full process for you — from registration to submission.
When is the Self Assessment deadline?
The UK tax year runs from 6 April to 5 April, and the online submission deadline is 31 January of the following year.
For example, for income earned between April 2024 and April 2025, the deadline to file your return is 31 January 2026.
We track all deadlines and file early to avoid HMRC penalties.
What documents do I need to provide?
You’ll need:
Proof of income (invoices, CIS statements, bank statements, etc.)
Expense receipts
P60 or P45 (if employed during the year)
Interest or dividend statements (if applicable)
Any additional supporting documents for allowances or reliefs
Our team reviews and organises everything before submission to ensure accuracy and compliance.
How do you help me maximise my tax refund or minimise my liability?
We carefully review all allowable expenses, deductions, and tax reliefs — including mileage, equipment, tools, home office costs, and more.
Our goal is to optimise your tax position legally, ensuring you pay only what you owe and claim every deduction you’re entitled to.
Every return is double-checked before submission to guarantee accuracy.
Can you file my return if I’ve missed previous years?
Yes. We can file late or multiple-year tax returns, correct previous errors, and communicate with HMRC to help you get back up to date.
Even if you’ve received penalty letters, our team can assist in reducing or removing fines where possible.
