Deadline Approaching: Your 2024/2025 Self Assessment Tax Return Guide for Gravesend Businesses

14 November 2025

The deadline for your 2024/2025 Self Assessment tax return is fast approaching. If you're a business owner or self-employed individual in Gravesend, now is the time to get organised and avoid costly penalties.

Important Dates You Cannot Afford to Miss

The Self Assessment tax year for 2024/2025 runs from 6 April 2024 to 5 April 2025. For businesses and self-employed individuals in Gravesend and across Kent, these deadlines are critical:

31 October 2025 - Paper tax return deadline
31 January 2026 - Online tax return and payment deadline
31 July 2026 - Second payment on account deadline

Who Needs to File a Self Assessment?

You need to submit a Self Assessment tax return if you:

  • Are self-employed as a sole trader and earned more than £1,000
  • Are a partner in a business partnership
  • Have rental income from property
  • Have income from savings, investments or dividends above certain thresholds
  • Are a company director (unless it's a non-profit organisation and you didn't receive payment)
  • Have foreign income

The Cost of Missing the Deadline

HMRC penalties start immediately after 31 January 2026:

  • £100 automatic penalty if your return is even one day late
  • Additional £10 daily penalties after 3 months (up to £900)
  • Further penalties of £300 or 5% of tax due (whichever is higher) after 6 months
  • Another £300 or 5% after 12 months
  • Interest charged on all late payments

Why Gravesend Businesses Should Act Now

Many small businesses and start-ups in Gravesend leave their tax returns until the last minute, creating unnecessary stress and potential errors. Starting early gives you several advantages:

Better Tax Planning: Early preparation allows time to identify legitimate tax reliefs and allowances you may be entitled to claim, potentially reducing your tax bill.

Improved Cash Flow Management: Knowing your tax liability well in advance helps you plan your finances and ensures you have funds available to meet your obligations.

Avoiding Errors: Rushing to meet the deadline increases the likelihood of mistakes, which can lead to HMRC enquiries and additional costs.

What You Need to Prepare

To complete your Self Assessment, gather:

  • Your Unique Taxpayer Reference (UTR) number
  • National Insurance number
  • Records of all business income and expenses
  • Bank statements and invoices
  • Details of any other income sources
  • Information about any tax reliefs you're claiming
  • Records of pension contributions
