Have you tried different lenses?

Try a controlled setup. Setup your camera at a fixed point, preferably using a tripod. Then get a piece of printed material and put it up perpendicular to the camera. Enable liveview disable autofocus. With manual focus, set it as sharp as can be. Check to see where the focus ring is positioned at (this needs to be as precise as possible). Now set it to autofocus and click the button just to focus. If the focusring has moved to a different position, you have a problem with either lens or body. Do this test with other lenses to see which it is. It may be that either needs calibrating.

I still recommend going through above exercise. If each lens has the same deviation (either front focusing or back focusing) then it is most likely an issue with the body. It could still be an issue with the lenses. On my 5D I can calibrate focus per lens and went through the exercise of calibrating each lens separately and found that the deviation per lens was quite remarkable.

Are you manually focussing or letting the lens auto focus for you. If problem only occurs manually, you may need to adjust the diopter on the lens viewer! Think it is called diopter

ok i will do that thank you

have you checked the diopter on the viewfinder? It's possible you adjusted that without knowing it and it's coming resulting in the focal point not ending where you want it.
