There are several:
- it seems zero balance invoices may be one problem, I was using that as a way to convert GST to non-GST sales. I would create a sales invoice where there was a negative qty with tax and a positive equal quantity without tax, balances to zero and it (did in 20.5.17) create a GST credit (yes, I know it’s probably not the best way, but in the way manager use to account for things, it worked… until it didn’t, lol. I will manually go back and fix those).
- (I’m not going to articulate this well, apologies in advance, and this one is probably my error, but) Applying tax in/on line items that are capital accounts > personal contributions > drawings… I probably shouldn’t have allocated a tax code on these lines, this was in error, but with a tax code applied, it is treated differently between manager versions. Even though the payment is entered “tax inclusive”, the reported entries under capital accounts is different. One is in total regardless of tax code, the other is after removing the tax value. (Again, I realise there shouldn’t be a tax value on this particular entry, but there is and manager is treating it differently between versions).
Here’s just one example of the second point:
Ahhh, it wasn’t until I dove into the payment / edit screen and noted it’s no longer payment & receipts but it is specifically a payment type. Have you finally separated the payment and receipts as far as tax implementation is concerned? That might be what it is. This had proven an issue in the past where other users had reported problems with returned items and the fact it was considered tax credits/debits (depending on supplier or customer)…
Funny thing is, that particular tax input on my part is incorrectly applied anyway, it was a drawing and should not have any tax implications whatsoever, so this has highlighted where I need to fix the entry, but what I don’t quite understand is it appears to me that one appears as an adjustment to a capital account with tax applied and one without, yet both entries are identical, after all, it’s just the backup database.
I’ve only attached one screen shot below, because they are both identical:
I just checked the BAS related to that particular entry and there is a difference in the total amount owing to the ATO of $2. I’m not about to go and edit a BAS of 4 years ago, but that ripples on through to today, highlighting my initial point that users should not only lock the database, but probably backup/save it, create a new one and transfer the balances so that mistakes like this don’t plague us in the following years.
I also found that $200 has been converted from the top G1-G9 section to the bottom G10-G20 section. The net effect is the same, but it has changed the reporting amount for those sections.
My tax liability as at today’s date has a net difference of $300 (and not in my favour).
If I take the date back to the end of the last financial year, every major figure is out:
- my assets have increased by $60
- liabilities up almost $270*
- equity down almost exactly $200
- my income to that year end is also down $265
* I think this means that although my tax liability today is $300, that’s based on an adjusted tax liability at the end of last financial year of $270, which I think means the adjusted liability of this year is just $30…
What I think I am going to have to do is split this database in two: create two backups, in one purge all entries prior to last tax lodgement and in the other purge all entries after tax lodgement and bring in new opening balances based on the old version, since that’s what I’ve used to lodge my tax and I’m not going to piss off the ATO at this present time 
Arrrgh… I’ve only just picked up (in a re-read of this before posting) my retained earnings are out in the top screen shots. I didn’t pick it up because the format of the summary report is slightly different and I thought it may have just been calculated differently, but in looking at it again, all these entries ($454 worth) are related to several payments over the date.
This is the same database open in two different versions of manager.
I’m only more confused now, shutting down for the night
