Waiting on income? Deferring payments into next year could reduce your 2026 taxable income, but there is a catch you should know first

For many small business owners, tax planning comes down to timing, paperwork and knowing what actually qualifies. A missed expense can mean paying tax on money that could have been excluded from taxable income. A credit can be even more valuable because it reduces the tax owed directly.

A deduction lowers taxable income. A credit reduces the tax bill itself. For example, a $2,000 deduction at a 22% tax rate would save $440. A $20,000 credit against a $50,000 tax bill would leave $30,000 to pay. The harder part is finding the opportunities that fit the business.

Which everyday business costs could save you money?

Start with expenses that are already part of running the business.Health insurance premiums may be deductible for eligible self-employed workers. Business travel, office rent, utilities, software subscriptions and professional services can also qualify when they meet the rules.


Vehicle expenses deserve particular attention. If a car is used for business, some of its costs may be deductible. The catch is documentation. Without clear records showing business use, a deduction can become difficult to defend.

The same issue comes up with a home office. Supplies, utilities, repairs and certain phone or internet costs may qualify when they are connected to the business. The simplified home-office method listed in the supplied material allows $5 per square foot, up to 300 square feet. Businesses can also use the actual-expense method.

Retirement savings can provide another route to tax savings. Traditional IRAs, 401(k)s, SEP plans and Solo 401(k)s may offer deductions depending on the taxpayer and plan. Roth IRA contributions are different because they are made with after-tax income and generally are not deductible.

For some business owners, the date money changes hands can matter. A freelancer using the cash method may be able to delay receiving income until the following tax year. If an invoice can legitimately be pushed into January, that income may fall into the next year's tax calculation instead of the current one.

That does not make the income tax-free. It only changes when it is reported. The strategy also does not work the same way for every business. Accrual-basis businesses generally recognize income when it is earned, which can make simply delaying payment less useful.

Expenses can be handled from the other direction. A business may be able to bring certain costs into the current year by paying for qualifying expenses before December 31. That could include equipment, insurance, rent, vendor bills or office supplies.

The supplied material also points to changes under the One Big Beautiful Bill Act. It lists a $2.5 million Section 179 deduction limit and permanent 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025. Those provisions can make the timing of major purchases more important than simply asking whether the expense is deductible.

Which credits, losses and records should you check before filing?

Tax credits deserve their own review because they work differently from deductions. The supplied material identifies the Earned Income Tax Credit, Small Business Health Care Tax Credit, Work Opportunity Tax Credit and Employer Credit for Paid Family and Medical Leave among the credits worth checking.

Eligibility can be very specific. The small-business health care credit, for example, is aimed at employers with fewer than 25 employees who pay at least half of employee premium costs.

Charitable giving can also produce a deduction for taxpayers who itemize and donate to qualified organizations. Keeping receipts and acknowledgment letters matters. Investment losses can help as well. Net capital losses can generally reduce taxable income by up to $3,000, with unused amounts carried forward.
