Individual working on tax returns while looking at cryptocurrency records

A growing number of individuals are expressing dissatisfaction with tax reporting processes related to cryptocurrency, especially on Coinbase. With new 2025 regulations mandating exchanges to report trades to HMRC, many feel uncertain about compliance due to missing historical transaction data.

Tax Reporting Challenges Persist

Users are increasingly frustrated about filing taxes from Bitcoin sales made years prior. One participant shared, "I'm declaring nothing. Chase me HMRC :O; my original exchange closed down (thanks China)." This sentiment reflects the anxiety surrounding record-keeping, leaving investors unsure of how to comply with the rules without accurate records.

While some users report using Koinly for a tax summary, they voice concerns about reliability. One user said, "It shows a profit/loss figure, but I'm perplexed on how it calculates that without buy prices." Many now doubt whether the figures generated without original purchase data will suffice for HMRC.

Another troubling aspect highlights Coinbaseโ€™s transition from its Pro service. Several users noted missing transactions during the consolidation. A user pointed out, "I see my old CB Pro transactions are gone; it might be due to merging back into normal Coinbase."

Seeking Guidance Amid the Chaos

In light of these ongoing challenges, valuable advice has surfaced in online discussions:

  • Bank Statements: Use them to trace funds moved to Coinbase, linking transfers with historical exchange rates for cost basis calculations.

  • Cost Basis Consideration: Some suggested a conservative approach, advocating rounding down estimates. One participant remarked, "If you cannot find these figures, use just fees paid."

  • Troubleshooting Coinbase: Users are encouraged to navigate Coinbaseโ€™s menu to access transaction statements correctly. "You really need to find your average cost basis, as that'll determine your profit," one user advised.

The Importance of Accurate Record-Keeping

As fears grow around being flagged as high-priority cases by HMRC, the community shares coping strategies to help manage reporting worries. With estimates indicating that up to 60% of crypto investors canโ€™t verify their cost basis by tax deadlines, clarity from exchanges may be crucial. Experts suggest services like Koinly may need to enhance their offerings to meet user needs.

Drawing Parallels with Past Crises

Reflecting on the 2008 financial crisis, many learned the value of thorough documentation amid crises. This historical lens highlights current crypto investors' journey for transparency and accuracy. Users are uniting, sharing strategies across forums akin to support networks formed during financial downturns, showcasing a resilient spirit.
