LLC filing S-Corp election for taxes

[Nathan Letourneau]

I've operated my business as a straight single member LLC for the last 10+ years. This year (2016) my income was much higher and I figured it might be useful to looking into the S-corp designation with the IRS. What is the deadline for filing this designation and still be able to use it for my 2016 income? If I file it for this year, do I have to continue with the S-corp designation for future years?

Any general rules of thumb for how to determine wage vs dividend for a house flipping business?

I asked my current tax guy a number of these questions but he wasn't "familiar" with them.  I think it's time to start shopping around for a new tax guy/gal that is well versed in real estate tax preparation.  Any suggestions for tax professionals/CPAs/etc?
