Two Windows products that take the return you have already prepared and get it to HMRC without a browser session. Gateway Solver Desktop handles PAYE/RTI and CIS, and VAT Solver Pro handles VAT under Making Tax Digital.
Nearly 10,000 companies and their agents file PAYE/RTI and CIS with it, and HMRC has recognised it since 2004. Full Payment Submissions, Employer Payment Summaries, CIS300 monthly returns, and subcontractor verifications go from your Windows desktop straight to HMRC, so nobody has to log into the Government Gateway by hand every time.
The digital link Making Tax Digital asks for, at a price that stays flat as you add companies. Submit a VAT return from the Excel, PDF, CSV, or XML file you already prepared, for up to ten companies, at £25 a month or £300 a year, confirmed on the invoice.
Comment moderation for a YouTube channel. You write the rules in plain English, it proposes a hold and gives the reason, and the final say stays with you. It never posts as you. The app is in beta, and it is free to start.
