You can always look at your Etsy bills for the year to determine what your fees paid were.
And you can download a report from Paypal with an account summary for the year.
But as for all of the other details that you need to know for tax time you will probably need to look at your own records.
Things that you need to know are
1) cost of goods sold - what your material costs were
2) total sales (gross and net)
3) shipping charges - what the customer paid
4) office supplies expenses
5) shipping expenses
6) equipment depreciation
6) new equipment purchases
7) office space (or portion of your home dedicated to the business)
8) car allowances
9) telephone allowance
10) utilities
11) inventory at both beginning and end of year
As far as sales go, I track everything on Excel spreadsheets. Nothing gets listed in the shop unless its on the spreadsheet.
When an item is sold I record the sale date, ship date, customer name, paypal fee, actual shipping cost and any notes.
When it comes to doing the taxes, all I need to do is tally the columns and I have 90% of the information that I need for taxes.
And each year between December 29th and Jan 2nd I do a complete physical inventory of all of my stock. That's the worst part of running the business.
