Payroll Accounts

You may have too many accounts, resulting in clutter of your Chart of Accounts. If the company is small, I would recommend you break your overhead wage accounts into two categories: "Directors and Officers" (including owners), and "Salaries". Naturally, if you have direct cost labor that belongs in COGS, then include it there. Employer payroll taxes do not need a bunch of accounts either. You could probably get away with a single "Payroll Taxes" expense account. Don't forget the liability accounts as well, but once again, keep that simple. Your detailed reports should tell you how much goes to local/state/federal agencies.

The only time I would consider multiple wage accounts is if your company is large enough to have a need to break your reporting down by department. Even then, hopefully, you have a software package that allows you to assign individual expense accounts to multiple departments so they can roll up into a consolidated report while still giving you your departmental reports.

Remember the role of financial reports is to give the reader useful information. If your stakeholders really need to know the breakdown of hourly versus salaried and state versus federal employer taxes, then give them that information. I have found that is not always the case for smaller businesses. Simplicity generally rules the day for me.

I agree with Daniel: simpler is always better, within the limits of the minimum information your stakeholders want to see in your reports.
In our case, we want to see net payroll vs. taxes vs. benefits (very useful to project total cost per employee), and we want to see bonuses and sales commissions separately, so we're using five accounts.
But if I were not analyzing payroll details by department in a separate spreadsheet, as I use payroll percentages to capitalize/allocate some of our expenses, including some of that payroll too, I would probably want more payroll accounts in the chart!... And if I were using Activity Based Costing, I would need even more details!
So I'd say it's really based on what you want to achieve with reporting and allocations.
