Fansly pays UK creators in USD by wire transfer, on a different schedule from OnlyFans. The income is still self-employment income for HMRC, still goes on a UK Self Assessment return, and still counts toward the £90,000 VAT threshold once converted to GBP at the right exchange rate.
The exchange rate matters more than most accountants notice. The bank gives you whatever rate the receiving bank used on the day; HMRC publishes a monthly average rate that is almost always slightly more favourable for the creator. We convert your Fansly statements at the HMRC monthly average rate, reconcile to the bank, and the difference goes into the right ledger account rather than getting lost.
Discretion works the same way as for our OnlyFans clients. The engagement letter describes your trade as online content. Your Fansly handle does not appear on any document we produce for HMRC, banks or mortgage providers.
