  We consider the upper and lower tail probabilities for the centered (by
time$/24$) and scaled (according to KPZ time$^{1/3}$ scaling) one-point
distribution of the Cole-Hopf solution of the KPZ equation when started with
initial data drawn from a very general class. For the lower tail, we prove an
upper bound which demonstrates a crossover from super-exponential decay with
exponent $3$ in the shallow tail to an exponent $5/2$ in the deep tail. For the
upper tail, we prove super-exponential decay bounds with exponent $3/2$ at all
depth in the tail.
