Guinea-Bissau cryptocurrency tax guide

What this guide covers

This guide summarizes Guinea-Bissau's thinly-sourced crypto tax position for 2025. dgci.gov.gw wasn't directly fetched. This is educational information, not individualized tax advice.

Tax treatment of cryptocurrency

One of this guide's own sources contradicts itself: it calls crypto gains exempt from capital gains tax, then in the same breath describes hard-fork and mining income as taxable. Guinea-Bissau, as a member of the eight-country WAEMU zone, falls under BCEAO regional oversight, which has issued cautionary guidance without a binding crypto ban across the zone (consistent with this knowledge base's findings for other WAEMU members). One tax-tracking source says Guinea-Bissau has no crypto-specific legislation and doesn't tax crypto gains. A separate source reports crypto gains as exempt from capital gains tax as of 2026, but in the same breath describes hard-fork proceeds and mining income as taxable ordinary income — a distinction suggesting some crypto-derived income is taxed even if simple disposal gains aren't. This guide doesn't treat the specific hard-fork/mining carve-out as confirmed, since it comes from only one source not corroborated elsewhere.

Common taxable events

• Per one source: hard-fork proceeds and mining income — reported as taxable ordinary income, distinct from simple disposal gains. This guide doesn't treat this as fully confirmed.

Potentially non-taxable events

• Crypto disposal gains — reported as exempt from capital gains tax as of 2026, per the sources reviewed, though this guide doesn't treat this as fully confirmed given the limited sourcing.
• Simply buying and holding crypto isn't a taxable event.

Tax rates and thresholds

This guide doesn't assert a confident rate. The reported exemption from capital gains tax, and the separate treatment of hard-fork/mining income as ordinary income, come from limited and not fully corroborated sourcing.

Cost basis and calculation

Not independently confirmed in this research pass.

Reporting and compliance

• This guide doesn't identify a confirmed individual reporting obligation specific to crypto under current Guinea-Bissau tax law.

Residency and cross-border issues

Not resolved in this research pass.

Example

This guide omits a worked tax example, given the limited and only partially corroborated sourcing on Guinea-Bissau's specific crypto tax treatment.

Limitations and review information

Tax year covered: 2025. Last verified: October 11, 2026. Known gap: dgci.gov.gw wasn't directly fetched; the reported capital-gains exemption and the separate hard-fork/mining income treatment come from limited secondary sourcing not independently corroborated. This is educational information only, not individualized tax advice — confirm current specifics directly with the DGCI or a qualified Guinea-Bissau tax professional.
