Quick Wins: Tax Tips You Can Apply This Week
- Separate finances: Dedicated business accounts help distinguish transactions, but do not automatically establish tax deductibility.
- Capture receipts automatically: scan or email to your accounting file; note business purpose.
- Track mileage properly: use an app; keep start/end, distance, and purpose.
- Review subscriptions: cancel unused tools and reclassify personal charges.
- Set quarterly estimate reminders: align payments to cash flow and safe-harbor rules.
Entity & Compensation: Don’t Leave Money on the Table
- Entity review: Distinguish the legal entity from its federal tax classification; review eligibility, compensation and administration costs before an election.
- Reasonable compensation for S-Corps: plan salary vs. distributions—document it.
- Retirement and benefits: Review eligibility, employee coverage, contribution limits and deadlines before claiming deductions. HSA eligibility depends on specific coverage and other requirements.
Sales Tax & Ecommerce: Avoid Costly Surprises
- Nexus checks quarterly: revenue/transaction thresholds can trigger new state filings.
- Marketplace facilitator rules: confirm what the platform remits vs. what you owe.
- Match to books: reconcile platform reports to sales tax filings and revenue accounts.
Documentation: Build a Supporting Records File
- Reconcile monthly: bank/credit cards; resolve uncategorized transactions ASAP.
- Keep support: invoices, contracts, W-9s, 1099s, mileage logs, asset invoices, and depreciation.
- Close with comments: each month, add reviewer notes for adjustments and estimates.
Month–Quarter–Year Cadence
Monthly
- Reconciliations, financials (P&L, Balance Sheet, Cash Flow), and sales tax (if applicable).
Quarterly
- Estimated-payment reviews where required and applicable payroll-tax obligations. Form 941 is generally quarterly; Form 940 is annual, with separate deposit requirements that may apply during the year.
Annually
- Returns: 1120S / 1065 / 1120 / Schedule C and owner 1040 coordination.
- 1099 workflows, depreciation strategy, and year-end planning.
For business recordkeeping guidance, review IRS Publication 583. Apply these tax tips to your records and confirm the required support with the responsible practitioner.
Common Mistakes We Fix
- Personal spending in business accounts (lost deductions, messy books).
- Late/incorrect S-Corp election; no documented reasonable compensation.
- No mileage, home office, or meal documentation.
- Untracked inventory or job costing errors; misclassified COGS.
- Sales tax nexus ignored after crossing thresholds.
Work with a Pro—Make the Maze Simple
- Monthly books closed on time—every month.
- Estimated-payment planning when included in the engagement; projections cannot eliminate unexpected liabilities.
- Return prep: 1120S/1065/1120/Schedule C + 1040 coordination.
- Enrolled agents have broad representation rights before the IRS. State-agency matters require a separate review of the agency's authorization and representative rules; federal enrollment does not by itself establish every state practice right.
Tax Tips FAQs
How do I know if I’m paying the right quarterly estimates?
We project your tax based on year-to-date results and apply safe-harbor rules. If revenue swings, we adjust vouchers mid-year.
Which deduction areas should a small business review?
Review ordinary and necessary business expenses, eligible business use of a home, depreciation and retirement-plan contributions under the rules for the applicable tax year. Eligibility, limits, elections and recordkeeping differ; these examples are not a ranking of the deductions businesses miss most often.
Can I switch accountants mid-year?
A mid-year transition requires review of outstanding records, deadlines and open obligations. Agree the historical review period and cleanup scope rather than assuming two or three months is sufficient.
Do you handle sales tax for ecommerce?
Discuss the states, products and sales channels involved, then confirm the scope of nexus analysis, registrations, filings and marketplace reconciliation in writing.
What software do you support?
Confirm support for your accounting version, payroll platform and ecommerce integrations. Ask which approved document and signing tools will be used and how access is controlled.
