Tax playbook
Tax season
Estimate federal tax, decide whether to itemize, then set withholding and retirement deferrals before year-end.
Tax season is a sequence, not a single form. First estimate federal income tax with this year’s brackets after the standard deduction. Then translate salary into take-home after FICA so the budget uses cash, not a W-2 headline. Then test whether SALT, mortgage interest, and charity beat the standard deduction. Only after those three numbers exist does it make sense to raise retirement deferrals or chase a refund.
The federal tax and paycheck tools share the same bracket library. The itemize tool uses the same standard deduction and SALT cap published on This year — tax. If a limit looks wrong, fix it there; do not treat a blog sentence as the source of truth.
This playbook does not file a return, model state tax, or replace a preparer. It orders the educational estimates so you do not set withholding from gross pay or itemize when the standard deduction still wins.
Step 1
Estimate the return
Run federal tax with this year’s brackets and the standard deduction. Note refund vs amount owed.
Step 2
Check take-home
Translate salary into a paycheck after federal income tax and FICA so the budget uses real cash.
Step 3
Itemize or standard?
Add SALT (capped), mortgage interest, and charity. Use the larger deduction.
Step 4
Use the space in retirement accounts
If you still have cash-flow room, raise 401(k) or IRA deferrals up to this year’s limit.
