Hello Mike,

First Thanks for your patience on this issue.

We have used a same decimal accuracy for 'tax' and 'accounts'. So If you
want to set your tax precision on 5 then you have to change your
account's decimal accuracy.

I think this is not create any problem because If you need decimal
accuracy for taxes  then your total must be have the same precision.
Which is works fine with current scenario.

If you want another precision for your taxes then you can customise it
easily at your end. Just create new precision for "taxes' and assign
this precision where you needed.

I think this is not a generalise issue but we needs more information on
this. How the real scenario working for this?

That's currently I am setting this as an "Opinion" and ask to experts
mailing list for "how to handle this type of scenario in real way".
After discussion on this we will decide the better way.

@Accounting Experts : Would you please share your views on this.

Thanks and more suggestions are welcomed!

Title:
  Tax Rates Round to Decimal Precision of Account + 2 - Should be
  variable

Status in OpenERP Addons (modules):
  Opinion

Bug description:
  In https://launchpad.net/bugs/667316 it was noted that tax percentage
  rates were limited to 2 decimals. As a "reasonable default" new code
  was introduced to fix this by changing that behavior to "use the
  decimal_precision of Account +2 for percentage values". While I can
  understand how this would work in most situations, we have just
  implemented an OpenERP system in Fresno CA where the local sales tax
  is in fact 7.975% (or 0.07975 when entered into OpenERP). Currently
  that rounds our rate to 7.98% given our Accounts are setup with a
  precision of 2. This does not calculate the correct tax amounts on our
  invoices (off by as much as a few dollars in some instances where the
  invoiced amount is large enough). We have no need for nor do we want
  our Accounts to round to anything beyond 2 decimals and the fix
  implemented in the bug above precludes using a tax rate such as the
  one noted that requires more than 4 decimal places (account +2 in our
  case is 4 but the rate we use needs 5).

  While I understand one can change the calculated tax value on the
  invoice, that is not behavior that I can expect of our end users on a
  regular basis. In the interim I have modified the code on our side in
  account.py to return account+3 instead of account+2:

  class account_tax(osv.osv):
      ...
      def get_precision_tax():
          def change_digit_tax(cr):
              res = pooler.get_pool(cr.dbname).get('decimal.precision').precision_get(cr, 1, 'Account')
              return (16, res+3)
          return change_digit_tax

  This works fine for me but I thought that since the previous bug noted
  Account+2 was a "reasonable default" that it should be just that... a
  default - which implies the decimal precision of the rate relative to
  the account precision should be variable and able to be set by the
  user. I personally believe that Account precision and Tax precision
  have nothing to do with each other and shouldn't be related in such a
  way to begin with. Shouldn't there be an actual entry in the
  decimal_precision table specifically for taxes that does not depend on
  and unrelated entities precision? Something like:

  class account_tax(osv.osv):
      ...
      def get_precision_tax():
          def change_digit_tax(cr):
              res = pooler.get_pool(cr.dbname).get('decimal.precision').precision_get(cr, 1, 'Tax')
              return (16, res)
          return change_digit_tax

  Just my thoughts.

  Current Environment:
  OpenERP 6.0.3 on Mac OS X 10.7 (the code above exists in the trunk as well)

  I'd be happy to help work something up if any one agrees or would find
  my suggestion to be useful.
