Key Takeaways

The OBBBA introduced five new deductions for 2026: tips (up to $25,000), overtime (up to $12,500/$25,000), car loan interest (up to $10,000), senior bonus ($6,000 for age 65+), and an above-the-line charitable deduction (up to $1,000/$2,000).
Above-the-line deductions reduce your AGI and benefit you whether you take the standard deduction or itemize.
The standard deduction for 2026 is $16,100 (single), $32,200 (MFJ), or $24,150 (HOH). Itemize only if your qualifying expenses exceed these amounts.
The SALT deduction cap increased to $40,000 for married couples, making itemizing worthwhile again for many taxpayers in high-tax states.
Self-employed taxpayers have access to dozens of business deductions that W-2 employees cannot claim.
This checklist covers more than 75 deductions across every major category.

How Tax Deductions Work

Tax deductions reduce your taxable income, which lowers the amount of tax you owe. They are not the same as tax credits, which reduce your tax bill dollar-for-dollar. The value of a deduction depends on your marginal tax rate. For example, if you are in the 24% bracket, a $1,000 deduction saves you $240 in federal income tax.

There are three categories of deductions:

Above-the-line deductions (also called adjustments to income): These reduce your adjusted gross income (AGI) directly. You can claim them whether you take the standard deduction or itemize. They appear on Schedule 1 and Schedule 1-A of Form 1040.
Standard deduction: A fixed amount based on your filing status that most taxpayers claim instead of itemizing.
Itemized deductions: Specific expenses you list on Schedule A. You should itemize only if your total qualifying expenses exceed the standard deduction.

Your goal is to identify every deduction you are entitled to and then determine whether the standard deduction or itemizing produces the lower tax bill.

New Deductions for 2026 (OBBBA)

The One Big Beautiful Bill Act created five new deductions. All are above-the-line (claimed on Schedule 1-A) and available whether you take the standard deduction or itemize.

1. Qualified Tips Deduction

Amount: Up to $25,000 per year

Phaseout: Begins at $160,000 MAGI (single) / $320,000 (MFJ)
Duration: Tax years 2025-2028
Note: Reduces income tax only, not FICA taxes

2. Qualified Overtime Deduction

Who qualifies: Non-exempt workers under the FLSA who receive overtime pay at 1.5x+ their regular rate
Duration: Tax years 2025-2028
Note: Overtime must be separately reported on W-2

3. Car Loan Interest Deduction

Who qualifies: Non-itemizers who make cash contributions to qualifying organizations
Duration: Starting tax year 2026

Above-the-Line Deductions (Available to Everyone)

These deductions reduce your AGI regardless of whether you take the standard deduction or itemize. Check each one — many taxpayers miss these because they assume deductions only matter if they itemize.

Retirement Contributions

Traditional IRA contributions: Up to $7,000 ($8,000 if age 50+). Deductibility depends on income and whether you have a workplace retirement plan.
Self-employed retirement contributions: SEP-IRA (up to 25% of net self-employment income, max $70,000), SIMPLE IRA (up to $16,500, plus $3,500 catch-up if 50+), or solo 401(k).

Health Savings Account (HSA)

HSA contributions: Up to $4,300 (self-only) / $8,550 (family). Must be enrolled in a qualifying HDHP. Contributions are tax-deductible, grow tax-free, and withdrawals for medical expenses are tax-free — the “triple tax advantage.”

Student Loan Interest

Student loan interest deduction: Up to $2,500 of interest paid on qualified student loans. Phases out at $80,000-$95,000 MAGI (single) / $165,000-$195,000 (MFJ).

Self-Employment Adjustments

50% of self-employment tax: Deduct half of the FICA taxes you pay on self-employment income.
Self-employed health insurance premiums: 100% of premiums for yourself, spouse, and dependents if you are self-employed and not eligible for employer coverage.

Education

Educator expense deduction: Up to $300 ($600 for married filing jointly if both are educators) for K-12 teachers who buy classroom supplies out of pocket.

Alimony (pre-2019 agreements)

Alimony paid under pre-2019 divorce agreements: Deductible by the payer (and taxable to the recipient). Alimony under agreements executed after 12/31/2018 is not deductible.

Moving Expenses (military only)

Military moving expenses: Active-duty military members can deduct unreimbursed moving expenses for a permanent change of station.

OBBBA Deductions (see above)

Qualified tips deduction (up to $25,000)
Qualified overtime deduction (up to $12,500/$25,000)
Car loan interest deduction (up to $10,000)
Senior bonus deduction ($6,000 for age 65+)
Above-the-line charitable deduction (up to $1,000/$2,000)

Standard Deduction vs. Itemized Deductions

2026 Standard Deduction Amounts

Filing Status	Standard Deduction	Additional (Age 65+)
Single	$16,100	+$2,050
Married Filing Jointly	$32,200	+$1,650 per spouse
Married Filing Separately	$16,100	+$1,650
Head of Household	$24,150	+$2,050

When to Itemize

Itemize if your total Schedule A deductions exceed your standard deduction. Common scenarios where itemizing wins:

You pay more than $10,000 in SALT (now deductible up to $40,000 for MFJ) and have significant mortgage interest or charitable contributions
You have very large medical expenses (exceeding 7.5% of AGI)
You experienced a casualty loss from a federally declared disaster
You live in a high-tax state and are a homeowner

The Math Example

A married couple in New Jersey itemizing in 2026:

SALT (property + state income): $28,000
Mortgage interest: $12,000
Charitable contributions: $5,000
Total itemized: $45,000 vs. standard deduction of $32,200

Itemizing saves this couple an additional $12,800 in deductions, worth approximately $3,072 at the 24% bracket.

What’s Changed in 2026

Five New OBBBA Deductions

The tips deduction, overtime deduction, car loan interest deduction, senior bonus deduction, and above-the-line charitable deduction are all new or newly available for 2026. These are above-the-line deductions claimed on Schedule 1-A.

SALT Cap Quadrupled

The SALT deduction cap increased from $10,000 to $40,000 for MFJ ($20,000 for MFS), making itemizing worthwhile again for millions of homeowners in high-tax states. The cap adjusts upward by 1% annually through 2029.

Standard Deduction Increased

The standard deduction rose to $16,100 (single) / $32,200 (MFJ) / $24,150 (HOH), reflecting inflation adjustments.

Bonus Depreciation Continues Phaseout

Bonus depreciation dropped from 60% (2025) to 40% (2026) as part of the TCJA’s scheduled phaseout. It will decrease to 20% in 2027 and 0% in 2028 unless Congress intervenes.

Enhanced Child Tax Credit

The per-child credit increased to $2,200 (from $2,000 under the original TCJA).

Common Mistakes to Avoid

Only thinking about deductions at filing time. The most valuable deductions (retirement contributions, HSA, estimated tax payments, charitable giving) require action before December 31 of the tax year.
Forgetting above-the-line deductions. Even if you take the standard deduction, you can still claim IRA contributions, HSA contributions, student loan interest, self-employment tax, and all OBBBA deductions. Review the full above-the-line list every year.
Not keeping receipts. The IRS can deny deductions you cannot substantiate. Keep records for at least three years (six if you underreport income by more than 25%).
Missing the SALT cap increase. If you stopped itemizing when the SALT cap was $10,000, revisit the math now that the cap is $40,000. You may find itemizing saves you money again.
Double-dipping. You cannot claim the same expense as both a business deduction and an itemized deduction, or use the same education expenses for both the AOTC and the Lifetime Learning Credit.
Ignoring state differences. Not all states conform to the OBBBA deductions. Your state return may not allow the tips, overtime, or car loan interest deductions. Check your state’s conformity status.
Skipping the HSA. If you have a qualifying high-deductible health plan and are not maxing out your HSA, you are leaving one of the most powerful tax breaks on the table.

Frequently Asked Questions

How many deductions can I claim?

There is no limit on the number of deductions you can claim, as long as you qualify for each one. You can claim all applicable above-the-line deductions in addition to either the standard deduction or itemized deductions.

Should I itemize or take the standard deduction?

Take whichever is larger. Add up all your potential Schedule A deductions (SALT, mortgage interest, charitable contributions, medical expenses above 7.5% of AGI). If the total exceeds $16,100 (single) or $32,200 (MFJ), itemize. If not, take the standard deduction.

What is the most commonly missed deduction?

HSA contributions, the student loan interest deduction, and the self-employment tax deduction are frequently overlooked because they are above-the-line and do not require itemizing. For 2026, the new OBBBA deductions (tips, overtime, car loan interest, senior bonus) are also commonly missed because they are new.

Can I deduct work-from-home expenses as a W-2 employee?

No. The home office deduction is available only to self-employed taxpayers (Schedule C filers). W-2 employees cannot deduct home office expenses, unreimbursed employee expenses, or work-related clothing under current law. The TCJA eliminated the miscellaneous itemized deduction for unreimbursed employee expenses.

Are the OBBBA deductions permanent?

The tips, overtime, car loan interest, and senior bonus deductions are available for tax years 2025-2028 only. The SALT cap increase runs through 2029. The TCJA extensions (rate structure, standard deduction, QBI deduction) are permanent.

What records do I need to keep?

Keep all W-2s, 1099s, receipts, bank statements, and documentation supporting your deductions for at least three years from the filing date. If you claim a deduction for a bad debt or worthless securities, keep records for seven years.
