"I have been using various Online Tax Return Services (eLodge, eTax Accountants) for a while now, and I can Pop - Tax is by far the easiest to use and best designed service of the lot, not to mention the most affordable.
Unlike the other services, Pop doesn't bombard you with questions after questions about deductibles or other tax items that 99% of the time are unrelated to your job - you choose an occupation from a (very comprehensive) drop down list and it tailors the questions to your chosen occupation.
It also gives you an average amount of tax deductions that people in the same occupation have previously claimed, which is helpful in case you forget that you had to use your private household as an office or had to buy equipment for your work.
Finally, the interface is by far the best - colourful without being too overbearing, useful hints and tips next to the (few) questions they ask you in case you are unsure, and they get back to you in a timely manner.
Did I also mention Pop - Tax is a very affordable service? To give you a comparison, Etax Accountants charged me over $100.00 AUD for a tax return of $300.00 AUD, which means they took 2/3 of my tax returns. Here's hoping Pop - Tax will smash aside the old business models and become the benchmark for all other Online Tax Returns Services."
