1. Weekly Tax Sweeps (25–35% Rule)
Move 25–35% of every profit deposit (1099, ACH, credit card) into a dedicated tax savings account automatically. Adjust percentage quarterly based on real margins and projections.
2. 12-Month Rolling Tax Forecast
Update a simple spreadsheet monthly: projected revenue, expenses, profit, tax liability, safe harbor target. Compare actual vs forecast → adjust sweeps and estimates early.
3. Estimate Autopay Setup (EFTPS/Direct Pay)
Schedule quarterly payments (Apr 15, Jun 15, Sep 15, Jan 15) via EFTPS or IRS Direct Pay. Automate safe harbor amount so you never miss a date. Calendar alerts for true-ups.
4. Payroll True-Ups & Owner Pay Rhythm
S Corp owners: review reasonable compensation quarterly. Increase withholding late in year to backfill short quarters. Use payroll to smooth cash flow and leverage even-year treatment.
5. Fixed vs Variable Spend Tagging
Tag expenses as fixed (rent, SaaS) or variable (ads, travel) in QuickBooks. Forecast variable spikes → adjust tax reserve. Prevents cash crunches from surprise tax bills.
6. Paperless Receipts & Immediate Capture
Scan/email receipts instantly (Dext, Expensify, QuickBooks app). Attach to transactions monthly. No receipt = no deduction. Cloud backup + searchable folders = audit armor.
7. Cash Floor + Profit Reserve
Set minimum cash floor (3–6 months operating expenses). Above floor, sweep extra profit to tax reserve or profit distribution. Protects against cash shortages when tax is due.
8. Monthly Mini-Close + Quarterly Deep-Close
Monthly: reconcile accounts, tag expenses, review sweeps. Quarterly: deep review of forecast vs actual, payroll true-up, estimate adjustment, documentation check.

W-2 withholding counts evenly across all quarters — even if increased late. Perfect for backfilling short early quarters.
