Allowable phone expenses for business purposes generally include the costs associated with using a mobile phone, landline, or related services for work, provided they are ordinary, necessary, and properly documented. For self-employed individuals, these expenses are typically claimed as a percentage of business use.
If you take a tech deduction, the IRS may ask for documentation—receipts, canceled checks, invoices, or bank records—for the expenses.
Only the business portion is deductible.
You need to determine what percentage of your cell phone usage is for business. For example: If 70% of your calls, apps, and data usage are business-related, you can claim 70% of your phone bill as part of your home office expenses.
For example, if you use your phone 60% for work, you can deduct 60% of your bill. You can also deduct the cost of a new phone, accessories, and additional charges incurred during business trips, but only the business-use portion is deductible.
Common work-related mobile phone tax deductions include:
The IRS allows taxpayers to deduct up to $3,000 of realized investment losses ($1,500 if married filing separately) against ordinary income each year. This deduction applies only to losses in taxable investment accounts and must be realized by December 31st to count for that tax year.
The section 179 deduction allows taxpayers, other than trusts and estates, to elect to expense a specified amount of the cost of qualifying property purchased for use in a business. For tax years beginning in 2026 the maximum deduction is $2,560,000, (2025, the maximum deduction is $2,500,000).
The IRS doesn't have a specific dollar limit for hobby income; instead, it focuses on profit motive: if you intend to make a profit, it's a business, but if it's for fun, it's a hobby, and you must report all income but can't deduct losses. Key is that you report all hobby income on Form 1040 as "other income," and if net earnings from self-employment are $400 or more, you owe self-employment tax, even if it's a side gig. The main difference from business is that you can't deduct hobby expenses (under current law) and must report all profits.
For example, many freelancers who rely heavily on home internet may deduct 50% or more of their internet bill. Light work use would require a lower percentage. Keep in mind that if you are a W-2 employee, you cannot deduct any portion of your home internet bill from your taxable income, even if you work from home.
Simple tweaks can lower your bill — leading to big savings over time.
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
A recent tax law ("One Big Beautiful Bill") introduced a new $6,000 bonus deduction for Americans aged 65 and older, available for tax years 2025-2028, reducing taxable income, not the tax itself, with income phase-outs starting at $75,000 MAGI for singles and $150,000 for joint filers. This deduction adds to existing standard deductions, provides up to $12,000 for couples, and requires a Social Security number and filing status other than Married Filing Separately.
The 150% reducing balance method divides 150 percent by the service life years. That percentage will be multiplied by the net book value of the asset to determine the depreciation amount for the year.
If the vehicle weighs more than 6,000 pounds and is used more than 50% for business, you can write off up to $28,900 in the first year, and potentially even more with bonus depreciation. Let's break it down: Buy a qualifying vehicle for $60,000, and you could write off a large portion of that cost in year one.
Limited circumstances for stand-alone 179 benefits.
The Section 179 expense limit and phase-out threshold ($2,560,000 and $4,090,000, respectively, for 2026) are now permanent parts of the tax code that are adjusted annually for inflation.
The Internal Revenue Code allows taxpayers to claim a capital loss deduction from their annual capital gains. Capital loss deductions from regular income are limited to $3,000 a year. Losses over this limit can be carried forward and claimed in future tax years if you make use of a capital loss carryover.
Here are some examples of records that can be used to claim deductions instead of using receipts:
You might be surprised to learn that simple business expenses like your cellphone bill or your new computer can be deducted from your taxable income. In fact, there are some fully-deductible expenses such as advertising and marketing costs, employee education and training, and certain legal fees.
The "$1000 instant tax deduction" refers to a proposed Australian tax policy, specifically from the Albanese Labor government in 2025, allowing eligible workers to claim a flat $1,000 deduction for work-related expenses without needing receipts, simplifying tax returns for those with lower expenses but potentially costing those with higher expenses, starting from 1 July 2026. It's an option to replace itemised work-related deductions, not an extra refund, and doesn't affect non-work-related deductions like charity.
