Self-Assessment Doesn’t Need to Be Stressful – Merranti Has You Covered
Every January, the same story plays out across the UK: sole traders, freelancers, and side-hustlers find themselves in a last-minute panic as the HMRC self-assessment deadline approaches. Receipts go missing, online logins are forgotten, and late filing penalties are looming.
But here’s the truth — self-assessment doesn’t need to be overwhelming. At Merranti Accounting, our role is to make the process simple, accurate, and stress-free. Here’s how we support you from start to finish.
1. What Exactly Is Self-Assessment?
Self-assessment is HMRC’s method for ensuring that individuals who don’t have all their income taxed through PAYE — or who have additional income streams — pay the correct amount of tax. You may need to file if you are:
A sole trader or freelancer
A landlord earning rental income
An individual with dividends or investment income
A company director receiving income not taxed through PAYE
Put simply, if you earn outside of traditional employment, HMRC expects you to complete a return. The deadline is 31 January each year, and missing it comes with immediate penalties.
2. Avoiding HMRC Penalties
Late filing is expensive. The penalties start at £100, but quickly escalate:
- Daily fines of £10 (up to 90 days)
- 5% of the unpaid tax if you miss payment deadlines
- Additional interest on outstanding amounts
At Merranti, we ensure your return is filed on time and your payments are made correctly. By keeping everything up to date, you avoid unnecessary fines and interest charges.
3. Claiming the Reliefs and Allowances You’re Entitled To
Submitting your return is not just about paying tax — it’s about paying the right amount. Many people either underpay (triggering HMRC investigations) or overpay (handing over more than necessary).
Our team identifies every allowable deduction, relief, and allowance you qualify for — from business expenses and property reliefs to pension contributions. We make sure your return is accurate and tax-efficient.
4. Preparing for Making Tax Digital (MTD)
HMRC is rolling out Making Tax Digital, which means self-assessment is shifting from one annual submission to quarterly digital updates. This will significantly increase the compliance workload for sole traders and landlords.
At Merranti, we prepare you in advance by setting up digital systems now. That way, when MTD becomes mandatory, you’re already compliant and confident — without added stress.
5. Keeping Records Organised
HMRC expects taxpayers to keep records for several years. But managing receipts, invoices, and logs can be challenging. Paperwork is often misplaced, leaving gaps when it’s time to file.
We provide digital record-keeping solutions to keep everything secure and accessible. From mileage logs to rental statements, your financial data is organised, accurate, and audit-ready.
6. More Than Just Paying Tax
Self-assessment isn’t just about settling your tax bill. It can also unlock opportunities to save or reclaim money. For example:
- Claiming back overpaid tax if you’ve had multiple jobs
- Claiming Gift Aid or pension contribution relief
- Managing the High Income Child Benefit Charge before it becomes an issue
We highlight these opportunities, ensuring you benefit fully from the system.
7. Handling HMRC Enquiries
If HMRC raises questions about your return, their language and requests can be difficult to navigate. In some cases, they may even open an enquiry into your finances.
Merranti acts as your representative, dealing with HMRC directly. We explain your situation, provide the necessary evidence, and protect you from unnecessary stress.
8. Year-End Planning for Better Results
The January deadline may be the most visible date, but real tax savings often come from planning before the tax year ends on 5 April. Adjusting expenses, contributions, and investments before that date can reduce your liability significantly.
We carry out annual reviews with our clients to identify opportunities, especially with allowances being reduced (for example, the dividend allowance now at £500 and the capital gains exemption reduced to £3,000). Careful year-end planning ensures you never pay more than necessary.
