WHY DIOGUARDI?
Tax amnesty is real legal protection
DioGuardi introduced the concept of Tax Amnesty to everyday taxpayers who have failed to file years of taxes or under-reported taxable income.
Tax Amnesty protects you from penalties and possible prosecution.
Legal protection is even more essential if the CRA is already demanding you file returns, or is looking for unreported income though an audit or net worth review.
When your tax balance is more than you can pay…
When you’re behind on filing returns…
When you’re facing an audit…
When CRA issues a lien on your home, wage garnishment or bank account freeze…
When anything about tax is keeping you up nights…
Call DioGuardi before you call any other kind of professional, and especially before you call an accountant.
The sooner you call, the more DioGuardi can do to protect you.
We protect clients against potential confiscation of assets and possible prosecution,
while offering tax amnesty for those who have yet to be caught for failing to file their taxes.

The Taxman is Watching: What Every Canadian Taxpayer Needs to Know and Fear

A must-read for every Canadian taxpayer, THE TAXMAN IS WATCHING is the essential guide to your relationship with your tax obligations and the Canada Revenue Agency. It’s a wake-up call for anyone who still believes the government is on your side. Written in plain English, and peppered with real world case histories and at times amusing anecdotes, Paul and Philippe DioGuardi expose the true agenda behind audits and tax credits, and offer important guidelines on what NOT to say when the Taxman calls.
Never Smile at a Crocodile: Confessions of a Tax Traveler

A companion piece to THE TAXMAN IS WATCHING, this new book from tax lawyer Paul DioGuardi – with an important chapter by his son, tax lawyer Philippe DioGuardi – captures the spirit of adventure that inspired a young and fearless lawyer to devote his professional practice years to tax.
In over 50 years of practice, Paul DioGuardi has seen the best and the worst of the Canada Revenue Agency from both sides of the crocodile’s jaws. If you thought tax was only for accountants, this book will change your mind.
