Self Assessment Services for Individuals and Businesses

Navigating Self Assessment: Making Complexity Simple with Artifin Accountants

If you are self-employed, have complicated financial circumstances, or have multiple sources of income, filing a self-assessment tax return with HMRC may seem difficult. The process requires precise record keeping, the calculation of taxable income, and adherence to strict HMRC deadlines. Even minor errors can result in fines, late fees, or overpayment of taxes.

Our accountants with extensive experience in Self-Assessment can help with that. From preparing your accounts and making the most of your allowances to filing your return online and managing your correspondence with HMRC, the entire process is handled for you.

What is Self Assessment?

HMRC uses the Self Assessment system to collect income tax from people and companies whose taxes are not automatically deducted under the Pay As You Earn (PAYE) program. Although the majority of UK workers have their taxes deducted directly from their paychecks, anyone with extra or untaxed income must file a Self Assessment tax return.

Your income, gains, expenses, and any other taxable activity for the financial year must be reported during this process. After that, HMRC uses this data to calculate your tax obligation. You might be eligible for a refund if you have already paid too much in taxes. To avoid penalties and interest, you must pay the remaining amount by the due dates if you owe more.

Self-assessment has an influence on multiple types of businesses and individuals/taxpayers, including high earners, company directors, freelancers, contractors, landlords, and self-employed sole traders. If you don’t file before the respective deadline, even if your earnings are nil or minimal, you could be fined by HMRC.

If you fall into the following categories, you must complete a Self Assessment tax return:

•  Self-employed sole traders earning over £1,000 per year

•  Freelancers, contractors, and gig workers

•  Company directors receiving dividends

•  Landlords with rental income

•  Investors earn from dividends, savings, or capital gains

•  People with foreign income

•  High earners (£100,000+)

•  Anyone with untaxed income not collected through PAYE

Many people opt to work with a professional for self-assessment because of the strict deadlines and sometimes complicated rules. An accountant guarantees that you never pay more than you owe, that all allowable expenses and reliefs are claimed, and that your tax return is accurate. This guarantees compliance while also lowering stress and saving time.

Why Choose Accountants for Self-Assessment?

Although HMRC offers online resources for individuals to file their returns, many people find the procedure much more complicated than they expected. It is easy to make costly mistakes when navigating long forms, interpreting tax laws, and determining which expenses are eligible for a claim. Small mistakes can result in penalties for non-compliance or in paying more tax than necessary.

A professional accountant guarantees that your Self Assessment tax return is completed accurately and efficiently, eliminating the need for guesswork. Working with a specialist allows you to:

•  Send in your return on time and accurately to avoid the stress of missing HMRC deadlines.

•  To lower your total tax liability, claim all permitted expenses and tax breaks

•  Make sure you don’t overpay or underpay by paying the appropriate amount of taxes

•  Adhere to HMRC regulations and avoid starting pointless inquiries

•  Prevent interest and late filing penalties, which can quickly escalate

•  Get expert tax planning guidance to help you save more of your earnings and prepare for future years

You can save a lot of time and feel more at ease knowing that your money is in capable hands by hiring a professional accountant to handle your tax return. This proactive measure maximises your savings, guards against mistakes, and guarantees that you continue to meet all HMRC requirements.

Self Assessment Tax Return Deadlines & Penalties

The Self Assessment tax return is filed for the fiscal year that runs from April 6 to April 5 of the following year. Submissions and payments must be made by January 31st. Even if there is no tax due, HMRC automatically applies fines and interest, so missing this deadline can be expensive.

Key payment deadlines:

• 31 January is the due date for the first payment for the next tax year

•  31 July is the due date for the second payment, if applicable

Late filing penalties include:

•  £100 initial fine for missing the deadline

•  £10 per day after 3 months (up to £900)

•  5% of tax due or £300 (whichever is greater) after 6 months

•  Another 5% or £300 after 12 months

By working with an accountant to ensure timely filing, you can prevent penalties and interest charges.
