GoSimple is the first HMRC-recognised app and aims to give taxpayers a quick and easy way to process and submit self-assessment tax returns.
The app offers a tailored experience for each user, making personalised recommendations on tax savings users qualify for.
It also claims to remove the need for an accountant, with users able to complete returns themselves for a set fee.
Rick Guttridge, managing director at Manchester-based Smoking Gun, said: “GoSimple has created a really useful and clever product that will save people time and money. Alongside the PR launch, we have taken on brand and digital communications partner status, creating joined up plans from positioning to content marketing.”
Amanda Swales, MD of GoSimple, added: “We were looking for an agency that understood the ethos of GoSimple and we felt Smoking Gun got it immediately. HMRC’s Making Tax Digital reforms has left a gap in the market for well designed software to offer users a simple tax return experience that they can undertake anywhere in the world.”
Smoking Gun, which has just enjoyed its most successful year to date with record fees and eight leading industry awards, has also won recent briefs from Magic Candy, Feel Good Drinks, Essential Cuisine and Peli UK.
