Tax problems aren't just a worry that hang over people's heads from January through April every year. Many of them go far beyond the numbers that you report, and they can require additional evidence that your bank statements and paychecks can't provide. Additionally, the IRS isn't the only source of those problems: state tax authorities are hungry for revenue, and if you divide your time among different states, you may find it difficult to establish nexus and may even have to file taxes in multiple states. Below are some of the most common personal income tax issues people are likely to face. 1. You didn't make (or underpaid) estimated tax payments. Self-employment is the most common cause of this. When you're used to having taxes withheld from your paychecks at work, it can be a shock to have to pay taxes yourself. You can end up owing not just a large amount of self-employment and income taxes, but also penalties for not making tax payments on time. Estimates must be deposited quarterly, or you will face an underpayment penalty. If your total tax due when you go to file is under $1,000, you won't have to worry about getting smacked with an underpayment penalty. However, it's a good idea to set aside at least 25%-30% of your income for estimated tax payments and commit to paying this amount every month if quarterly taxes are too complicated to figure out. Other situations like freelancing on the side or rental income while you're still employed can also cause you to fall short at tax time, so make sure to have extra taxes withheld from your paycheck if you don't want to make estimated payments. State tax payments also shouldn't be neglected. 2. You didn't correctly file state tax returns after moving. Moving to a state with little or no income taxes like Nevada or Florida can be appealing if your bank account feels squeezed in high-tax states like New York or California. Many people divide their time between multiple states for work or personal reasons, and if it's not just a two- or three-week creative retreat or corporate assignment, it can make nexus difficult to determine in some cases. With the prospect of a lower tax burden becoming even more appealing, it seems logical to just move to the tax-haven state you've been eyeing. But even after you file for a change of address with the postal service, change your voter registration, and get recognized as a resident by your new state, the high-tax state that you left is likely to also still treat you as one. Typically, you must spend at least 183 days of the year in the other state and maintain a primary residence there. Simply having property in another state won't do if the rest of your family doesn't also live and wait there for you after your work or travel. Where you spend time outside of work also matters because where you sleep every night is ultimately what counts. If your move is indeed permanent and your residency is valid, you may have to file a part-year resident tax return for the final months you stayed in the old state. You won't need to worry about it for following years, but keep track of how many days were spent in each state before and after moving day. 3. You neglected to file state income tax returns as a nonresident. If you have business or rental income in another state, you may be required to file state tax returns as a nonresident. If this income is significant, it can end up producing a large tax bill if you're unprepared. If you have an out-of-state job, chances are that your payroll provider may also be incorrectly withholding taxes for the appropriate state and/or city. In concentrated regions like the tri-state area, especially for New York City and Philadelphia residents, ensure that city taxes are being correctly withheld if you are a resident, and that withholding curtails if that is no the longer the case. There are usually reciprocity agreements among states and municipalities in areas where state lines cross, but you should carefully check to make sure you don't owe nonresident taxes in addition to what you owe your home state. Failure to make tax payments on time, and to the right agency, are income tax problems that are often overlooked and can quickly spiral out of control. To avoid these issues and many more, contact our office so we can consult you on your state and local taxation, as well as rules for establishing nexus.

2026 IRS Mileage Rates: Key Updates and Insights

The IRS has rolled out the inflation-adjusted mileage rates for 2026, offering taxpayers an efficient way to claim deductions for vehicle-related expenses incurred for business, charity, medical, or moving purposes. These adjustments reflect the continued economic shifts impacting car operation costs.

Effective January 1, 2026, the new standard mileage rates are established as follows:

  • Business Travel: Increased to 72.5 cents per mile, inclusive of a 35-cent-per-mile depreciation allocation. This marks a rise from the 70 cents per mile rate set for 2025
  • Medical/Moving Purposes: Reduced slightly to 20.5 cents per mile, down from 21 cents in the previous year, reflecting the variable cost considerations.
  • Charitable Contributions: Consistent at 14 cents per mile, a fixed rate unchanged for over a quarter-century.

As is typical, the business mileage rate considers the integral fixed and variable costs of automobile operation. Meanwhile, the medical and moving rates remain contingent on variable expenses as determined by the IRS study.

It is critical to note that the One Big Beautiful Bill Act (OBBBA) held firm on disallowing moving expense deductions except for specific cases within the Armed Forces and intelligence community, marking a substantial shift since 2017.

When engaging in charitable work, taxpayers might opt for a direct expense deduction over the per-mile method, covering gas and oil costs. However, comprehensive upkeep and insurance costs are non-deductible expenses.

Business Vehicle Use Considerations: Taxpayers can alternatively compute vehicle expenses using actual costs, which might benefit from shifting depreciation rules, particularly through bonuses and first-year advantages. Keep in mind, however, reverting from actual cost calculations to standard rates in subsequent years is restricted, particularly per vehicle protocol and when exceeding four vehicles in concurrent use.

Additionally, parking, tolls, and property taxes attributable to business can be deducted independently of the general rate, an often-overlooked advantage by many business owners.

Tax Strategies for Employers and Employees: Reimbursements based on the standard mileage framework, providing the right documentation is in place, remain tax-free for employees. Meanwhile, the elimination and continued prohibition of unreimbursed employee deductions continue, with particular exceptions offered to qualified personnel across specific occupations.

Opportunities for Self-employed Individuals: Entrepreneurs remain eligible for deductions on business-related vehicle use via Schedule C, with potential to account for business-use interest on auto loans.

Heavy SUVs and Deduction Advantages: Heavier vehicles exceeding 6,000 pounds but under 14,000 pounds open opportunities for substantial tax deductions through Section 179 and bonus depreciation avenues. The lifecycle of such a vehicle bears implications on recapturing initially claimed deductions, urging cautious tax planning.

Educator's Deduction Reform: Key Changes Under OBBBA

The One Big Beautiful Bill Act (OBBBA) introduces significant enhancements for educators' tax deductions starting in 2026, offering both strategic opportunities and planning considerations for educators who qualify. With the reinstated itemized deduction for qualified unreimbursed expenses, educators have a broader spectrum of financial relief. This is complemented by the retention of the $350 above-the-line deduction, allowing educators to maximize their tax benefits by selectively allocating expenses between these avenues.

Understanding the nuances of these changes is crucial for educators and financial advisors alike. The dual-option deduction strategy can potentially enhance tax efficiency, thereby aligning with broader financial planning goals.
