Monthly Obligations
- Close your books within 15-20 business days of month-end — reconcile all bank accounts, credit cards, and loan balances to zero variance.
- Deposit federal payroll taxes (FICA, federal income tax withholding) semi-weekly or monthly depending on your deposit schedule as determined by Form 941 lookback rules.
- Review accounts receivable aging and follow up on invoices over 30 days — cash collection is just as important as revenue recognition.
- Reconcile your cap table to your general ledger equity accounts to catch any discrepancies from new grants, exercises, or terminations.
