In their own words
Taxmo
Taxmo is UK bookkeeping and tax software for sole traders, freelancers, contractors, expats and small businesses. It tracks income and expenses and updates estimates for Income Tax, National Insurance and VAT as entries are added. Paid plans can submit VAT returns to HMRC through the Making Tax Digital API. Taxmo prepares and reviews Self Assessment returns but does not submit them to HMRC; MTD for Income Tax submission is marked as coming soon. Receipt capture extracts supplier, amount, date and VAT from photos and PDFs. Bank imports use read-only, on-demand Open Banking authorization, while CSV statement uploads have no history limit. The accountant platform syncs in both directions with Xero, QuickBooks and FreeAgent, and deadlines can be exported as an iCal feed. Taxmo offers web, iOS and Android apps plus API access; Pro subscribers get a read-only REST API limited to 300 requests per 15-minute window. There is a free plan and a free trial; paid plans start at £9.99/mo, excluding VAT.
