Any solo tax preparer knows how difficult it can be to prepare a complicated return and then also review it again. One area I did make a mistake in a prior year was an entry for a 1099-MISC that did not actually end up flowing through to income, and I failed to catch it. I have always reviewed to make sure everything of relevance was entered; my issue was in the fact that I was not verifying total income against the totals of source docs, and for this particular 1099 I had it entered in one place but not another that actually allowed it to flow through as income. I have modified my habits to help with this, but looking for a more efficient method.
Have other solo tax preparers found any simple and efficient way of inputting income figures (my biggest concern) into a spreadsheet or similar to quickly compare to Page 1 Total Income on the 1040?
