How to make sure you get good advice

Tell your accountant everything. Everything. Everything.

This isn't poker, show your whole hand. Treat them like your therapist. They can then help you plan for your future better. If you're ever tempted to lie about your income, don't. Instead, hire an advisor (ideally different to your regular accountant) and ask them lots of "hypothetical" questions. If you don't walk away happy, hire another.

You'll quickly find out that you don't need to lie to get your taxes down, you just need to ask the right "what if?" questions
