Taxes March 14, 2025

Introduction

Staying on top of crypto tax throughout the year is crucial for avoiding last-minute stress, costly mistakes, and potential HMRC penalties. Whether you struggled with tax filing last year or want to be more proactive, a structured approach to crypto tax management can make compliance easier and more efficient.

This guide outlines practical steps to help UK crypto investors track, manage, and report their tax obligations smoothly throughout the year.

 

1. Educate Yourself on Crypto Tax Regulations

Many crypto investors face challenges with tax reporting simply because they don’t fully understand HMRC’s rules. Staying informed is the first step to compliance.

  • Read up on UK crypto tax rules and how income tax and capital gains tax apply to different transactions.
  • Follow trusted sources such as HMRC guidance and crypto tax experts.
  • Consider using crypto tax software to simplify calculations.
  • If your situation is complex, consult a crypto-savvy accountant for professional guidance.

By taking the time to learn how crypto tax works, you avoid misinformation and costly errors when filing your returns.

 

2. Plan Ahead and Set Tax Deadlines

Mark important tax deadlines in your calendar and set your own internal deadlines to stay ahead.

  • Key UK Tax Deadlines for Crypto Investors:
    • 5th October – Deadline to register for self-assessment if you’re filing for the first time.
    • 31st January – Deadline to submit your tax return online and pay your tax bill.

Pro tip: Set a personal deadline at least a month before the official deadline to allow time for review and corrections.

 

3. Stay on Top of Crypto Tax Admin

Crypto tax involves a lot of record-keeping, so getting organised early is key.

  • Create a digital tax folder where you store all tax-related documents.
  • Keep detailed records of your transactions, including:
    • Type of cryptoasset
    • Transaction date
    • Number of units
    • Value in GBP at the time of the transaction
    • Wallet addresses and exchange details
    • Cumulative total of investment units held

By staying organised throughout the year, you’ll have everything ready when tax season arrives.

 

4. Take Ownership of Your Crypto Data

HMRC places the responsibility on individuals to maintain accurate records. The best way to ensure compliance is to download and store your transaction data regularly.

  • Set a reminder to export exchange and wallet data every month.
  • Use crypto tax tools to consolidate and review transactions in real-time.
  • Store your records in a secure digital location to prevent data loss.

Taking control of your data reduces the risk of missing transactions and errors in your tax return.

 

5. Use Crypto Tax Software to Simplify Tracking

Manual crypto tax calculations can be overwhelming, especially if you trade frequently. A tax software solution like Block3 Finance can make the process easier by:

  • Automatically tracking your crypto portfolio across multiple exchanges and wallets.
  • Calculating capital gains and losses based on HMRC’s share matching rules.
  • Generating tax reports that align with self-assessment forms (SA108).
  • Providing real-time tax insights so you can plan and reduce your liabilities.

Using crypto tax software saves time, improves accuracy, and ensures compliance with HMRC regulations.

 

6. Keep Track of Your Crypto-Related Expenses

Many crypto investors forget to track their expenses, leading to missed tax deductions.

  • Keep records of all tax-deductible expenses, including:
    • Trading fees
    • Gas fees for transactions
    • Subscriptions to crypto tax software
    • Costs for professional tax advice

Although HMRC’s stance on deductible expenses for crypto investors is still evolving, it’s better to keep records and claim deductions where possible.

 

7. Register for Self-Assessment Early

If you need to file a tax return for crypto, don’t wait until the last minute to register.

  • The registration deadline is 5th October for first-time filers.
  • Register early to get your Unique Taxpayer Reference (UTR) on time.
  • Store your login details securely so you don’t lose access when you need them.

By registering early, you avoid last-minute stress and potential late-filing penalties.

 

8. Be Prepared When Filing Your Tax Return

Once tax season arrives, having all your documents ready will make filing easier.

Checklist of what you need for filing:
      HMRC login details
      Unique Taxpayer Reference (UTR)
       National Insurance number
      Details of untaxed income from the tax year
      Crypto tax reports from Block3 Finance
      Records of deductible expenses
      P60 or employment income records
      Self-assessment form SA108 for capital gains tax reporting

Following this checklist ensures that you file accurately and avoid mistakes that could trigger an HMRC inquiry.
