How to solve BJT amplifier clipping a signal?
Two major things wrong. First the resistor values in your circuit are way too high to properly have a decent standing DC current from collector through emitter. Yes you need a DC current to permanently bias the transistor into the correct part on the load line and this will need tens if not hundreds of mA.

The 2nd problem is one of understanding - any inductor be it a normal inductor or the primary of a transformer cannot have a sustained DC voltage across it and, as such, it will cause the collector signal voltage (when you get the biasing right as per point 1) to rise and fall equally above and below 9 volts. Potentially, with a perfect transistor (rarer than unaffordium and costlier than unobtainium) you can get 18 volts p-p from a 9 volt DC power source.

Thirdly, as a hint, get rid of the emitter capacitor - you'll never ever be satisfied with distortion figures for this type of class A amplifier with too much capacitance there even when you get the biasing right (hint look at the emitter resistor being more like ten ohms).
