What are "client's drawdowns?" Are you describing your taxpayer taking draws from their sole proprietorship (not an expense)? Or, distributions from their S Corp (not an expense)?

And is the business really the only type of taxable income this person will have?

Yes drawdowns like distributions, he takes a monthly transfer from the business account. 

Yes, that's the only taxable income. 

Thanks

It's a sole proprietorship. It's registered as an LlC. 

Thanks

draws aren't an expense, you pay tax on your profit, regardless of how much money you actually took for yourself.

How about if the client pays himself a salary instead of a drawdown. 

Thanks 

Sole proprietors can’t pay themselves wages.

"Sole proprietors can’t pay themselves wages."

Because all of it is theirs, already. They are not a cost to their own business.

"It's registered as an LlC."

You mean LLC?

Have you considered Safe Harbor for estimates? See this article:

That's what I rely on when a client has a constantly changing taxable income, and it's especially useful when they are on a constant increase. You just have to explain the difference between Safe Harbor and actually having paid in enough in estimate payments that they will hardly owe a balance, or at the least, they intend to be prepared if there is a large balance due (but at least they are not subject to penalty and interest).

Can I use the tax planning feature on Pro series to do the same as noted above? 

Thanks

Thanks so much.
