Tax Slayer (previously NP Accounting) was established in 2005. We changed our name in 2018 to reflect our moto which is to help small businesses save tax and grow. 



At Tax Slayer, our mission is "to provide the best professional services and support to ensure the success and happiness of our clients"

Our clients want more than a standard accountant who can successfully lodge a business tax return - they want specialised support to maximise the profitability of their business. They want an accountant who is actively guiding them to better business and financial outcomes. They want an expert who can help them minimise their tax and maximise the performance of their business.

We look forward to working closely with you to grow your profit, wealth and freedom.
