Polyconomic

For Accountants

Handle your crypto clients without becoming a crypto expert.

Your clients have crypto. They do not always know what to do about it. Polyconomic gives you the tools to handle their HMRC obligations quickly, accurately, and without spending hours on transaction-level data.

What you get

Built for professional use

Multi-client dashboard

All your clients in one place. Switch between accounts instantly. No separate logins, no password managers.

HMRC SA108-compatible reports

Every report follows the Capital Gains Summary layout. Every figure is traceable back to the underlying transactions. Clean, reviewable, audit-ready.

All HMRC matching rules applied

Same-day rule, 30-day rule, and share pool applied automatically in the correct legal order. No manual calculation required.

Import from anywhere

API connections for automatic sync, CSV for manual imports. We handle every major UK exchange format and auto-detect column mappings.

Capital gains and income separated

Staking rewards, mining income, and other crypto income reported separately from capital gains — exactly as HMRC requires.

Full audit trail

Every calculation traces from the final report figure back to the individual transactions. If HMRC asks questions, you have the answers.
