Used TIAC last  year when we renewed in April.  Last year when we signed up, ALTA was a flat $200 for first year no matter what your income.
WELL, the 200 went to 225 for income 0-100k.  With 3 employees, we fall into the 100,001 to 400,00 range, which is $400 for ALTA dues this year.
Though our renewal quote was only $2400, add the $400 and I got a better quote somewhere else.

ALl I can say is that TIAC is very professional and courteous and helpful, in the long run, it didn't work out for us.
