20% across the board?  I hope they are preparing returns with some complexities rather than just basic returns.

Lots of big money returns in that group....clients with millions of dollars  WAY out of my client income range.

I just submitted to join....if thats the case @Just Lisa Now! they'll be waaaay out of my clients range as well.

I'm doubling the fees for all of my clients.  I figure half of the clients will leave so I will only have to work half as hard this year and collect the same amount of revenues.  
I should confess that I think about going that route every year, but I still haven't pulled the trigger on it yet

I hear stories about doing this. Double the fees and maybe 10% leave. By now they know you are worth the money. GO FOR IT!!!

I like the doubling of fees and only having to work half as hard.

We will be tacking a fee for 199A calculation that reads "199A Calculations - resulting in a tax savings of $xxxx.

How about a fee for "State itemized deductions that IRS did not allow calculations - resulting in a tax savings of $xxxx"?

NATP has a fee study in their members area.  I bump my fees 10% across the board for everyone without much fuss.  After all, my clients can afford to drink one less can of Coke a year.
