For many taxpayers, January feels like the natural time to start thinking about taxes. The forms begin arriving, you start gathering documents, and you schedule time with your tax preparer. But by then, much of the year has already happened. Getting organized this fall can make a meaningful difference.
Start by understanding where you stand
Not every taxpayer needs the same level of review. For some W-2 employees, a basic withholding review may be enough. The IRS provides a free Tax Withholding Estimator that can help workers estimate whether federal withholding is appropriate based on their income and circumstances.
It can be especially useful after multiple jobs, a change in income, a spouse starting or changing work, investment income, gig or freelance income, or an unexpectedly large tax bill or refund last year. But more complicated situations may require more than a calculator. If you have a business, rental property, investments, or multiple sources of income, a tax professional may need to look at the bigger picture. The goal is not necessarily to predict your exact tax bill. It is to establish a reasonable expectation from the information available now.
For a straightforward W-2 question, start with the IRS estimator. For a decision that needs more context, a focused tax consultation can help clarify the facts that matter.
Don’t overlook your records
For business owners and rental-property owners, tax preparation becomes much harder when the underlying records are incomplete. Some of the first things we look at are categorization, whether transactions are in the appropriate accounts; reconciliation, whether the accounting software matches bank and other financial accounts; mileage, whether business vehicle use is supported; and completeness, whether income and expense records can support preparation of the return.
The IRS explains that good business records help taxpayers prepare returns and support the items reported on them. Mileage is another area where recordkeeping matters. For 2026, the optional IRS business standard mileage rate is 72.5 cents per mile, but using it still requires records that support the business use.
If you know your records need attention, do not wait for filing season to discover how much reconstruction is needed. Review the bookkeeping cleanup and catch-up path for a clearer starting point.
Don’t let tax preparation become bookkeeping cleanup
One situation we encounter during tax season is a taxpayer who is not actually ready for tax preparation yet. The books may need cleanup. Transactions may need to be reconstructed. Accounts may not have been reconciled. Business and personal activity may need to be separated. Mileage records may be incomplete.
Before the return can be prepared properly, the underlying records may need attention. That can turn what should have been a straightforward tax-preparation engagement into a much longer process. The earlier you identify those issues, the more options you generally have for addressing them before filing season becomes busy.
For self-employed clients, Schedule C activity is part of an individual return. Partnerships, S-Corporations, and corporations have separate entity returns. The small-business tax preparation page explains the entity-return path and the records that usually need to come forward.
A large refund isn’t necessarily a sign that everything went perfectly
For employees, another important fall question is: am I withholding the right amount of federal income tax? A large refund can certainly feel good. But it generally means more was paid into the system during the year than was ultimately required based on tax liability. On the other hand, insufficient withholding can result in an unexpected balance due, and potentially other consequences depending on the circumstances.
The goal is not necessarily to maximize your refund. It is to have withholding reasonably aligned with your expected tax situation. For some taxpayers, the IRS estimator may be sufficient. For others, particularly those with businesses, rentals, investments, or multiple income sources, a more comprehensive review may make sense.
What can you do this fall?
For individual taxpayers
- Review your current withholding.
- Consider whether your income has changed significantly.
- Think about major life changes that could affect your return.
- Start organizing tax documents as they become available.
- Don’t wait until January to discover that something is missing.
For business and rental-property owners
- Review your profit and loss information.
- Make sure accounts are being reconciled and transactions are categorized.
- Separate business and personal activity appropriately.
- Review mileage and other supporting records.
- Identify missing or incomplete records and consider whether estimated tax payments are keeping pace with your situation.
- Get professional eyes on the numbers if the situation is complicated.
January is for preparation, not discovering everything for the first time
There will always be things you cannot know until the year is over. That is normal. But that does not mean you have to enter January completely in the dark. A fall review can give you a better understanding of where you stand, what records still need attention, and whether there are issues to address before tax preparation begins.
