Like the others here, I plug in every number from my pay stub.
Doing so allows you to break down exactly how much tax you
are paying, the amounts of pre or post tax deductions, etc. An
example w/o the numbers:
2012-02-06 Stanford University Paycheck
Assets:USAA:Checking $_,___.__
Assets:403b:SCRP $___.__ ; 403b:
employer basic
Assets:403b:SCRP $___.__ ; 403b:
employer match
Assets:403b:SCRP $___.__ ; 403b:
pre-tax
Assets:403b:SCRP $___.__ ; 403b:
post-tax
Expenses:Tax:Federal:Withholding $_,___.__
Expenses:Tax:Federal:MED/EE $__.__
Expenses:Tax:Federal:OASDI/EE $___.__
Expenses:Tax:Ca:Dis/EE $__.__
Expenses:Tax:Ca:Withholding $___.__
Expenses:Insurance:Medical $__.__
Expenses:Insurance:Vision $_.__
Income:Stanford:Salary $-_,___.__
Income:Stanford:Pager $-___.__
Income:Stanford:SCRP:Basic $-___.__
Income:Stanford:SCRP:Match $-___.__
The '; 403b:...' markers allow me to run a report like this:
ledger bal 403b:SCRP --pivot=403b -b 2012 -e 2013
which will provide a report on employer, pre-tax, and post-tax
contributions to a 403(b) retirement fund (something in the
US that lets people save for retirement in lieu of a pension,
but which has very specific rules about pre-tax and total
contribution limits).
