About

Decades of experience, built around your business.

Completed Tax is led by Brian Byrnes, who brings decades of experience in bookkeeping, payroll and tax to businesses in Greensborough, across Melbourne and right around Australia.

Meet Brian

Brian Byrnes, principal of Completed Tax.

Completed Tax is a registered tax agent, and Brian brings decades of experience, so your bookkeeping, payroll, BAS and income tax returns are looked after by someone accountable for getting them right, not just entered into software.

Completed Tax is based in Greensborough, in Melbourne's north-east, and works with business owners there, in the surrounding suburbs and right across Australia, in person where it helps and remotely everywhere else. Completed Tax was previously known as Completed Books.

The approach is tailormade: bookkeeping, payroll, BAS and GST, income tax returns, business advisory and cloud accounting setup, shaped around how your business actually runs rather than a one-size-fits-all package.
