FICA, FUTA, Federal Withholding, Oh My!

Making sense of IRS Publication 15

In general, the base module (l10n_us_hr_payroll) should form the basis for a 'US Employee' Salary Structure (that would be the parent of a state specific Salary Structure if need be). This module provides all of the Salary Rules (calculations), registers, and Partners (e.g. EFTPS).

The secondary module (l10n_us_hr_payroll_account) is a very basic mapping between the stock Odoo US Chart of Accounts and the various Salary Rules from above. These mappings are very generic and probably not appropriate for general use, and is meant for testing or inspiration. (Odoo's Chart of Accounts lacks specific accounts for things like Employee Net Payable, and I suggest that you create your own!)
