Tax Time 2026 is upon us and officially began on Monday January 26, 2026. For Maine residents personal returns for 2025 will be due on Wednesday, April 15, 2026. Business tax returns for S corporations, multimember LLC's, and partnerships will be due on Monday, March 16, 2026. Your return is considered filed on time if the envelope is properly addressed, has enough postage, is postmarked by the due date, and is physically deposited in the mail by the due date. These timely filing rules are subject to IRS Regulations pertaining to IRC Section 7502. I strongly recommend electronic filing of returns or certified mail.
Note that accountants must receive a signed e-file authorization form in order to have legal permission to file a return on your behalf. If I do not receive a signed and dated e-file authorization form then I can't file your taxes.
While extension forms can always be filed (Form 4868), bear in mind that an extension of time to file is never an extension of time to pay taxes. You can extend your 2025 personal return until Thursday, October 15, 2026. But your tax bill is legally due and payable on April 15 for Maine residents. The IRS and Maine will charge late payment penalties and interest on unpaid balances. This is the number one issue I deal with for clients who are on extension.
Why do extensions exist in the first place? The answer is that many people and companies honestly need additional time to prepare an accurate tax return that is signed under penalties of perjury. Another reason is that some clients provide tax information to their accountant close to a tax filing deadline, leaving the accountant with insufficient time to generate an accurate tax return. Finally, and it does pain me to have to clarify this, accountants tend to go on vacation after tax season is over.
Here is a list of key changes for 2025 returns filed in 2026:
(1) STANDARD DEDUCTION
The new IRS standard deduction for 2025 is as follows: $31,500 for married filing a joint return; $15,750 for single or married filing separately; and $23,625 for head of household. Seniors aged 65 and older will receive an extra $6,000 deduction each. And taxpayers may claim an additional $1,350 deduction for dependents.
Few people itemize their deductions on Schedule A. The sum of all of your itemized deductions must exceed your standard deduction in order for you to benefit from itemizing. More people are likely to itemize in 2025 because the new tax law allows you to deduct up to $40,000 for state and local tax on Schedule A. The prior year limit was $10,000.
(2) MILEAGE RATES
The 2025 IRS mileage rate is 70 cents per mile; the 2026 rate is 72.5 cents per mile. Many clients ask me if they should use the mileage method or the actual method when deducting vehicle costs. My rule of thumb for answering this question is as follows: if you buy a low cost vehicle and put a ton of miles on it, use the mileage method.
Alternatively, if you purchase a more expensive vehicle and have only a moderate amount of miles per year then think about using the actual method. Every time you acquire a business vehicle you must decide which method to use. If your business operates more than 4 vehicles then the IRS requires you to use the actual method.
The actual method allows you to deduct vehicle costs for gas, repairs, vehicle insurance, etc. Even though you use the actual method, you are still required to keep track of business mileage.
(3) IRS INTEREST ON TAX UNDERPAYMENTS
Yes it costs money to borrow from the IRS. Interest on underpayments of estimated tax is now 7% for the first quarter of 2026. This rate is adjusted quarterly by IRS based on market conditions. The rate has not been this high for many years. You can avoid this cost by accurately estimating the amount of tax to pay IRS quarterly. Estimated tax payments are remitted to IRS using Form 1040-ES and are due on April 15, June 15, September 15 and January 15. Use Form 2210 to calculate the penalty for underpayment of estimated tax.
(4) CHOICE OF ENTITY
For business owners probably one of the most important tax issues to consider is your choice of entity. If you start a new business and do nothing it will be classified by the IRS as a sole proprietorship, leading to potentially adverse tax results. Work with an accountant or tax advisor for your business and find the best entity to use, such as an S corporation or LLC.
(5) BUY A DEDUCTION: FUND YOUR IRA
Year 2025 IRA contribution limits are as follows: Under age 50 $7,000 per person
Age 50 or older $8,000
Note that the deduction for funding an individual retirement account may be reduced or eliminated if you are covered by a retirement plan by your employer. Year 2026 funding limits for IRA's were increased to $7,500 under age 50 and $8,600 age 50 and older.
The ability to fund a ROTH retirement plan for 2025 starts getting phased out if your modified adjusted gross income exceeds a threshold: $150,000 for singles and $236,000 for married filing joint. Special rules apply to married filing separate returns. If you fund a ROTH even through your income exceeds these thresholds then you will owe a penalty.
(6) MAINE IS NICE TO SOME RETIREES - THE PENSION DEDUCTION
Maine's pension income deduction has increased to $48,216. Note that your actual deduction is reduced by the amount of social security benefits you received (see Box 5 of your social security benefit statement.)
(7) FULL BONUS DEPRECIATION ON NEW ASSETS IS BACK
So-called bonus depreciation allowed for business owners depreciating newly acquired assets for their business has been increased to 100% for 2025. Section 179 accelerated depreciation has remained mostly the same.
(8) NEW MAINE TAX ON BUSINESSES
Effective January 1, 2025, Maine enacted a new 1% payroll tax to fund up to 12 weeks of paid medical leave. For employers with 15 or more workers the tax is divided equally between the employer (0.5% tax) and the employee (0.5% tax withheld from paychecks.) For smaller employers the tax rate is 0.5% withheld from employee paychecks. See:
This new tax and related administrative burden will continue the pattern of making it even harder to operate a business in Maine with employees. The paid 12 weeks of leave may become, de facto, a new entitlement program that reduces the full time working hours available to employers from 2,000 per year (current full time work year including 2 weeks of vacation) to perhaps only 1,500 hours per year. Employers will either have to hire more employees to cover the shortfall of workers or make other painful adjustments to prices, size of the business, etc. Payroll costs and fees will increase substantially. The 1% initial tax rate is likely to increase over time as more and more workers cash in on this new entitlement program.
As long as Maine remains a one party state we will most likely continue our descent into socialism with bigger and bigger state government and more and more regulation of private business. Few people have access to the knowledge and insight that exposes the fundamental error of these socialistic schemes. Here are easily readable and brief reports from the Cato Institute that explain precisely why government mandated medical leave laws have profoundly adverse consequences:

(9) YEAR 2025 FEDERAL TAX BRACKETS
Here are 2025 federal income tax brackets which apply to taxable income and are based on your filing status:
| Tax Rate | For Single Filers |
For Married Individuals Filing Joint Returns |
For Heads Of Households |
| 10% | $0 to $11,925 | $0 to $23,850 | $0 to $17,000 |
| 12% | $11,925 to $48,475 | $23,850 to $96,950 | $17,000 to $64,850 |
| 22% | $48,475 to $103,350 | $96,950 to $206,700 | $64,850 to $103,350 |
| 24% | $103,350 to $197,300 | $206,700 to 394,600 | $103,350 to $197,300 |
| 32% | $197,300 to $250,525 | $394,600 to $501,050 | $197,300 to $250,500 |
| 35% | $250,525 to $626,350 | $501,050 to $751,600 | $250,500 to $626,350 |
| 37% | $626,350 or more | $751,600 or more | $626,350 or more |
(10) MAJOR TAX BENEFITS FOR SHORT TERM RENTALS
Short Term Rentals provide key tax benefits. The restoration of 100% bonus depreciation may allow business owners with so-called 'air b n b' businesses to claim substantial depreciation deductions for land improvements, interior renovations, and general business assets. Vacation rentals, cabins, and beach houses may be classified as businesses, which means they are NOT subject to the limits on rental real estate losses imposed by IRC Section 469.
Business activity that meets the above standards should be reported on Schedule C, not Schedule E page 1. If the average period of customer use is 7 days or less Form 8582 does not apply to these types of businesses pursuant to Treasury Regulation §1.469-1T(e)(3)(ii). The initial year for a new short term rental could claim very large depreciation deductions.
Prepare for an audit if large losses are reported on Schedule C. Keep all underlying records. And bear in mind that Maine may subject such businesses to sales tax on short term rentals. Collect this tax from your customers, then file and pay the sales tax to Maine Revenue Services.
(11) NEW DEDUCTION FOR VEHICLE LOAN INTEREST
The new tax law created a deduction for interest paid on loans for US made vehicles. The deduction is claimed on Part IV of Schedule 1-A. See here for more guidance:
https://www.irs.gov/newsroom/treasury-irs-provide-guidance-on-the-new-deduction-for-car-loan-interest-under-the-one-big-beautiful-bill
(12) NO TAX ON SOME TIPS AND OVERTIME PAY
The new 2025 tax law made $25,000 of tip income and $12,500 of overtime pay tax free. Information to claim this deduction should be provided by employers on Form W-2. The tip deduction is claimed on Part II of Schedule 1-A and the overtime deduction is claimed on Part III of Schedule 1-A.
CONGRESS CONTROLS THE PAST AND THE PRESENT
Bear in mind that Congress has the power to change tax laws retroactively. Thus, every word of this article written on February 8, 2026 could be erased or modified by future laws enacted by Congress.
Remember that the very best answer for you is to always pay the legal minimum tax: not one cent more.
