There are a few ways to keep track of where to start the tape. This guide contains tips for finding the end of tape.
To keep from losing the end of postage tape, place a paper clip on the sticky side of the tape just below where you are making the cut. Store the tape with the paper clip, and you are ready to go next time you need to use the tape. The paper clip is easy to pull off and thick enough to keep from losing the end of the tape.

How many times have you put the tape dispenser down to grab something , pick the tape back up and the end had stuck to the roll ugh! Take an old credit card or hotel key, cut it 1/2 inches and use as a tongue to secure the tape from sticking to itself. You will be able to use the plastic tongue to pull the tape out easily.
I don't know if anyone does this already but I discovered something that helps me tremendously! Put a paper clip at the start of the tape. When you need some, take your length and then put the paper clip in place before tearing it off. Now you'll always know where the end is, no more turning and turning and searching. :)
Have you ever spent too much time looking for the end of your tape roll, very frustrating! Just break a bread tag in half or use a paper clip and attach on to the end of the tape roll, no more hassles.
Need help finding the end of packaging/scotch tape? Place a toothpick under the end. It will be easy to remove and replace with no tape wasted.
If you find it hard to locate the end on packing or strapping tape, place a thin ribbon or string under the last portion where you removed tape from roll.
