Topic: VAT Report wrong ???

I am having trouble with the Tax Inquiry giving me wrong values. I attach the GL Account transactions and the Tax Enquiry screenshot.
According to GL account Transactions the net payable should be 11135.17(this is correct), yet the tax enquiry report either 12640.86 or 11633.37, depending or whether I use Tax Enquiry or General Ledger Reports->Tax Enquiry.
What am I doing wrong.

Re: VAT Report wrong ???

The period in the first report is Period:    01-03-2018 - 31-03-2018.
The period in the second report is Period: 01-02-2018 - 31-03-2018.
Synching them might solve your issue.

Re: VAT Report wrong ???

There are no transactions for 01/02/2018 - 28/02/2018. Started using FA 1/03/2018. To double check I set the tax parameters to tax period 1 and tax last period to 1. Same result if I set my reporting period to 1/3/2018 - 31/3/2018.
Also changed system date to 1/4/2018, no difference except the default dates for the reports are then correct, which would be normal behaviour for FA.

Re: VAT Report wrong ???

Report 1 GL Transactions balance is correct:
Ending Balance - Opening Balance = 726,990.22 - 715,855.05 = 11,135.17

Report 2 Tax Balance wrong:
(Outputs - Inputs) * 14 / 100 = 11,633.37 = (Output Tax - Input Tax) = (16,642.49 -  5,009.12)

This is clearly a case of rounding off errors. The first report is done line by line computation of tax, whilst the second one computes the tax on the total value at the end.

@joe: Should we not attempt to simulate the first in the code for the second?

Re: VAT Report wrong ???

Report 2 Tax are not only rounding, difference are 11 633.37 - 11 135.17 = 498.20.

Also why are there a difference between:
Tax Enquiry = 11633.37 and
General Ledger Reports->Tax Enquiry = 12640.86

3 different results on the same set of books.

Re: VAT Report wrong ???

Stand corrected.

Are there any entries that have been voided that get included in the second report that match the difference?

Re: VAT Report wrong ???

By voided, do you mean under Setup->Void a Transaction? If so, no transactions voided.

Re: VAT Report wrong ???

Even an Edit of a Journal Entry means a voiding and then a new entry.

Re: VAT Report wrong ???

I did some journal entries, like prompt payment discount, had to use journal to reverse and re-allocate as no tax credit are given for the discount.

Will try in new month and see if I can do better with no journal reversals.

Thanks for the input though.
