Most tax savings happens before the year ends, not after your tax return is already locked in.
Once the year closes, your CPA can report what happened. Planning is about deciding what happens while you still have time to act.
If you want predictable tax savings, you need a year end checklist you run every year. The owners who consistently save money are not the ones chasing new tricks. They are the ones reviewing the same high impact items annually and executing what fits.
This guide is a practical year end tax planning checklist for business owners and real estate investors. Use it to spot opportunities, avoid missed deductions, and reduce the chance of a surprise balance due.
The First Rule: Start With Updated Numbers
Before you do anything, update your numbers.
You need:
Year to date profit and loss
Balance sheet
Payroll reports if you run payroll
Fixed asset list or large purchase list
Rental property income and expense summaries
Estimated tax payments and withholding totals
If your bookkeeping is behind, catch it up first. Planning without real numbers is guessing.
-
Forecast Your Full Year Profit
Estimate your final profit for the year based on year to date results and expected activity.
This drives everything else: tax bracket, estimated taxes, retirement contributions, payroll adjustments, and whether timing moves matter.
-
Confirm Estimated Taxes and Withholding Are On Track
Check what you have already paid through estimated payments and withholding.
If you are behind, you may need an additional payment to reduce penalties and avoid a giant balance due.
-
Review Owner Pay Strategy
If you are an S corp owner, confirm wages are reasonable and consistent with the year’s profit.
If profit is higher than expected, you may need to adjust wages or distributions so the year ends clean.
-
Run a Distributions and Owner Draw Review
Confirm owner distributions and draws are recorded correctly in bookkeeping.
Misclassified distributions can create tax confusion and inaccurate financials.
-
Audit “Uncategorized” and “Miscellaneous” Expenses
This is one of the easiest places to find missed deductions.
Reclassify items into correct categories so deductions are not buried.
-
Review Meals and Travel Documentation
Meals and travel deductions are only as good as your records.
Make sure you have receipts and notes showing business purpose, attendees when relevant, and dates.
-
Confirm Contractor W9s and 1099 Readiness
If you paid contractors, confirm W9s are on file now.
Do not wait until January to chase people.
-
Review Vehicle Deductions and Mileage Logs
If you claim vehicle deductions, confirm you have mileage logs and support.
If you do not, start now. Reconstructing later is weak.
-
Update Fixed Asset Lists and Depreciation Planning
Make a list of any equipment, furniture, improvements, or major purchases.
If you do not track assets, you can miss depreciation or misclassify purchases.
-
Identify Timing Opportunities for Expenses
Depending on your accounting method and facts, you may be able to accelerate certain business expenses.
The goal is not to spend money you do not need to spend. The goal is to pull forward necessary spend when it helps.
-
Evaluate Retirement Plan Contributions
Retirement contributions can be one of the cleanest year end planning moves.
Confirm what you are eligible to contribute and whether cash flow supports it.
-
Review Health Insurance and Benefit Planning
Owner benefits vary by entity type and payroll setup.
Make sure health insurance reporting and reimbursements are handled correctly, especially for S corps.
-
Confirm Accountable Plan Reimbursements Are Done
If you use an accountable plan, reimbursements should be current and documented.
Avoid year end lump sum reimbursements with no reports.
-
Review Home Office Documentation
If you qualify, confirm you have measurements, allocation calculations, and supporting bills stored.
If you do not qualify, do not force it.
-
Real Estate: Repairs vs Improvements Review
If you own rentals, review projects and classify them properly.
Make sure improvements are added to asset schedules and repairs are documented as repairs.
-
Real Estate: Cost Segregation Decision Review
If you purchased or placed a property in service this year, evaluate whether a cost segregation study makes sense.
Do this before filing season, not after.
-
Real Estate: Track Suspended Passive Losses
If you have rentals with losses, confirm you are tracking passive loss carryforwards by property.
These are future tax assets, but only if you track them.
-
Review Any Property Sales or Large Gains
If you sold real estate or assets, review gain reporting, depreciation recapture, and estimated tax impacts.
Large events should trigger an estimated tax update.
-
Review Entity Structure and Next Year Changes
Year end is a good time to review whether your entity structure still fits.
If you are considering an S corp election or changing payroll strategy, it is often best to plan for next year with clean implementation.
-
Create a Next Year Tax Plan Calendar
The biggest step is making the process repeatable.
Set a calendar for:
Monthly bookkeeping close
Quarterly estimated tax review
Mid year planning check
Year end planning meeting
When you schedule planning, it stops being reactive.
