Generally speaking, tax return mistakes are a lot more common than you probably realize. Taxes are naturally complicated, and the paperwork required to file them properly is often convoluted. This is especially true if you're filing your taxes yourself — and all of this is in reference to a fairly normal year as far as the IRS is concerned. The 2018 tax year, however, certainly does not qualify as a "normal year." With the passage of the Tax Cuts and Jobs Act, even seasoned financial professionals are having a hard time digesting all of the changes that they and their clients are now dealing with. All of this is to say that if you've just discovered that you've made a BIG mistake on your tax return this year, the first thing you should do is stop and take a deep breath. It happens. It's understandable. There ARE steps that you can take to correct the situation quickly — you just have to keep a few key things in mind. Fixing Tax Return Mistakes: Here's What You Need to Do All told, you have three years from the date that you originally filed your tax return (or two years from the date you paid the tax bill in question) to make any corrections necessary to fix your mistakes. If nothing about your return ultimately changes, you probably don't have anything to worry about — in fact, there's a good chance that the IRS will catch the mistake and fix it themselves. This is especially true in terms of math errors, or if you've left out an important document. The IRS will probably send you a letter letting you know what happened and what you need to do to correct it. If fixing the mistake ultimately results in you owing more taxes, you should pay that difference as quickly as possible. Penalties and interest will keep accruing on that unpaid portion of your bill for as long as it takes for you to pay it, so it's in your best interest to take care of this as soon as you can afford to do so. If you've made a much larger mistake (like if you understated or overstated your income, for example), you'll need to file what is called an amended tax return. This is essentially your "second chance" at getting things right, and the timetable above still applies. Understand, however, that ALL errors must be corrected in the amended return. This means that if you find three errors that will reduce your tax liability and two that actually increase it, you are legally required to correct all five. You can't correct only the mistakes that benefit you. An amended return can be used to correct a variety of issues, including but not limited to ones like:

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.
