Self-employment tax: A refresher on how it works

Details: Published: 19 November 2024 19 November 2024

If you own a growing, unincorporated small business, you may be concerned about high self-employment (SE) tax bills. The SE tax is how Social Security and Medicare taxes are collected from self-employed individuals like you.

SE tax basics

The maximum 15.3% SE tax rate hits the first $168,600 of your 2024 net SE income. The 15.3% rate is comprised of the 12.4% rate for the Social Security tax component plus the 2.9% rate for the Medicare tax component. For 2025, the maximum 15.3% SE tax rate will hit the first $176,100 of your net SE income.

Above those thresholds, the SE tax’s 12.4% Social Security tax component goes away, but the 2.9% Medicare tax component continues for all income.

How high can your SE tax bill go? Maybe a lot higher than you think. The real culprit is the 12.4% Social Security tax component of the SE tax, because the Social Security tax ceiling keeps getting higher every year.

To calculate your SE tax bill, take the taxable income from your self-employed activity or activities (usually from Schedule C of Form 1040) and multiply by 0.9235. The result is your net SE income. If it’s $168,600 or less for 2024, multiply the amount by 15.3% to get your SE tax. If the total is more than $168,600 for 2024, multiply $168,600 by 12.4% and the total amount by 2.9% and add the results. This is your SE tax.

Example: For 2024, you expect your sole proprietorship to generate net SE income of $200,000. Your SE tax bill will be $26,706 (12.4% × $168,600) + (2.9% × $200,000). That’s a lot!

Projected tax ceilings for 2026–2033

The current Social Security tax on your net SE income is expensive enough, but it will only worsen in future years. That’s because your business income will likely grow, and the Social Security tax ceiling will continue to increase based on annual inflation adjustments.

The latest Social Security Administration (SSA) projections (from May 2024) for the Social Security tax ceilings for 2026–2033 are:

2026 - $181,800
2027 - $188,100
2028 - $195,900
2029 - $204,000
2030 - $213,600
2031 - $222,900
2032 - $232,500
2033 - $242,700

Could these estimated ceilings get worse? Absolutely, because the SSA projections sometimes undershoot the actual final numbers. For instance, the 2025 ceiling was projected to be $174,900 just last May, but the final number turned out to be $176,100. But let’s say the projected numbers play out. If so, the 2033 SE tax hit on $242,700 of net SE income will be a whopping $37,133 (15.3% × $242,700).

Disconnect between tax ceiling and benefit increases

Don’t think that Social Security tax ceiling increases are linked to annual Social Security benefit increases. Common sense dictates that they should be connected, but they aren’t. For example, the 2024 Social Security tax ceiling is 5.24% higher than the 2023 ceiling, but benefits for Social Security recipients went up by only 3.2% in 2024 compared to 2023. The 2025 Social Security tax ceiling is 4.45% higher than the 2024 ceiling, but benefits are going up by only 2.5% for 2025 compared to 2024.

The reason is that different inflation measures are used for the two calculations. The increase in the Social Security tax ceiling is based on the increase in average wages, while the increase in benefits is based on a measure of general inflation.

S corporation strategy

While your SE tax bills can be high and will probably get even higher in future years, there may be potential ways to cut them to more manageable levels. For instance, you could start running your business as an S corporation. Then, you can pay yourself a reasonably modest salary while distributing most or all of the remaining corporate cash flow to yourself. That way, only your salary would be subject to Social Security and Medicare taxes. Contact us if you have questions or want more information about the SE tax and ways to manage it.

Unlocking the mystery of taxes on employer-issued nonqualified stock options

Details: Published: 15 November 2024 15 November 2024

Employee stock options remain a potentially valuable asset for employees who receive them. For example, many Silicon Valley millionaires got rich (or semi-rich) from exercising stock options when they worked for start-up companies or fast-growing enterprises.

We’ll explain what you need to know about the federal income and employment tax rules for employer-issued nonqualified stock options (NQSOs).

Tax planning objectives

You’ll eventually sell shares you acquire by exercising an NQSO, hopefully for a healthy profit. When you do, your tax planning objectives will be to:

1. Have most or all of that profit taxed at lower long-term capital gain rates.

2. Postpone paying taxes for as long as possible.

Tax results when acquiring and selling shares

NQSOs aren’t subject to any tax-law restrictions, but they also confer no special tax advantages. That said, you can get positive tax results with advance planning.

When you exercise an NQSO, the bargain element (difference between market value and exercise price) is treated as ordinary compensation income — the same as a bonus payment. That bargain element will be reported as additional taxable compensation income on Form W-2 for the year of exercise, which you get from your employer.

Your tax basis in NQSO shares equals the market price on the exercise date. Any subsequent appreciation is capital gain taxed when you sell the shares. You have a capital loss if you sell shares for less than the market price on the exercise date.

Let’s look at an example

On December 1, 2023, you were granted an NQSO to buy 2,000 shares of company stock at $25 per share. On April 1, 2024, you exercised the option when the stock was trading at $34 per share. On May 15, 2025, the shares are trading at $52 per share, and you cash in. Assume you paid 2024 federal income tax on the $18,000 bargain element (2,000 shares × $9 bargain element) at the 24% rate for a tax of $4,320 (24% × $18,000).

Your per-share tax basis in the option stock is $34, and your holding period began on April 2, 2024. When you sell on May 15, 2025, for $52 per share, you trigger a $36,000 taxable gain (2,000 shares × $18 per-share difference between the $52 sale price and $34 basis). Assume the tax on your long-term capital gain is $5,400 (15% × $36,000).

You net an after-tax profit of $44,280 when all is said and done. Here’s the calculation: Sales proceeds of $104,000 (2,000 shares × $52) minus exercise price of $50,000 (2,000 shares × $25) minus $5,400 capital gains tax on the sale of the option shares minus $4,320 tax upon exercise.

Since the bargain element is treated as ordinary compensation income, the income is subject to federal income tax, Social Security and Medicare tax withholding.

Key point: To keep things simple, the example above assumes you don’t owe the 3.8% net investment income tax on your stock sale gain or any state income tax.

Conventional wisdom and risk-free strategies

If you had exercised earlier in 2024 when the stock was worth less than $34 per share, you could have cut your 2024 tax bill and increased the amount taxed later at the lower long-term capital gain rates. That’s the conventional wisdom strategy for NQSOs.

The risk-free strategy for NQSOs is to hold them until the earlier of 1) the date you want to sell the underlying shares for a profit or 2) the date the options will expire. If the latter date applies and the options are in-the-money on the expiration date, you can exercise and immediately sell. This won’t minimize the tax, but it eliminates any economic risk. If your options are underwater, you can simply allow them to expire with no harm done.

Maximize your profit

NQSOs can be a valuable perk, and you may be able to benefit from lower long-term capital gain tax rates on part (maybe a big part) of your profit. If you have questions or want more information about NQSOs, consult with us.

The amount you and your employees can save for retirement is going up slightly in 2025

Details: Published: 12 November 2024 12 November 2024

How much can you and your employees contribute to your 401(k)s or other retirement plans next year? In Notice 2024-80, the IRS recently announced cost-of-living adjustments that apply to the dollar limitations for retirement plans, as well as other qualified plans, for 2025. With inflation easing, the amounts aren’t increasing as much as in recent years.

401(k) plans

The 2025 contribution limit for employees who participate in 401(k) plans will increase to $23,500 (up from $23,000 in 2024). This contribution amount also applies to 403(b) plans, most 457 plans and the federal government’s Thrift Savings Plan.

The catch-up contribution limit for employees age 50 or over who participate in 401(k) plans and the other plans mentioned above will remain $7,500 (the same as in 2024). However, under the SECURE 2.0 law, specific individuals can save more with catch-up contributions beginning in 2025. The new catch-up contribution amount for taxpayers who are age 60, 61, 62 or 63 will be $11,250.

Therefore, participants in 401(k) plans who are 50 or older can contribute up to $31,000 in 2025. Those who are age 60, 61, 62 or 63 can contribute up to $34,750.

SEP plans and defined contribution plans

The limitation for defined contribution plans, including a Simplified Employee Pension (SEP) plan, will increase from $69,000 to $70,000 in 2025. To participate in a SEP, an eligible employee must receive at least a certain amount of compensation for the year. That amount will remain $750 in 2025.

SIMPLE plans

The deferral limit to a SIMPLE plan will increase to $16,500 in 2025 (up from $16,000 in 2024). The catch-up contribution limit for employees who are age 50 or over and participate in SIMPLE plans will remain $3,500. However, SIMPLE catch-up contributions for employees who are age 60, 61, 62 or 63 will be higher under a change made by SECURE 2.0. Beginning in 2025, they will be $5,250.

Therefore, participants in SIMPLE plans who are 50 or older can contribute $20,000 in 2025. Those who are age 60, 61, 62 or 63 can contribute up to $21,750.

Other plan limits

The IRS also announced that in 2025:

The limitation on the annual benefit under a defined benefit plan will increase from $275,000 to $280,000.
The dollar limitation concerning the definition of “key employee” in a top-heavy plan will increase from $220,000 to $230,000.
The limitation used in the definition of “highly compensated employee” will increase from $155,000 to $160,000.

IRA contributions

The 2025 limit on annual contributions to an individual IRA will remain $7,000 (the same as 2024). The IRA catch-up contribution limit for individuals age 50 or older isn’t subject to an annual cost-of-living adjustment and will remain $1,000.

Plan ahead

The contribution amounts will make it easier for you and your employees to save a significant amount in your retirement plans in 2025. Contact us if you have questions about your tax-advantaged retirement plan or want to explore other retirement plan options.

The nanny tax: What household employers need to know

Details: Published: 07 November 2024 07 November 2024

Hiring household help, whether you employ a nanny, housekeeper or gardener, can significantly ease the burden of childcare and daily chores. However, as a household employer, it’s critical to understand your tax obligations, commonly called the “nanny tax.” If you hire a household employee who isn’t an independent contractor, you may be liable for federal income tax and other taxes (including state tax obligations).

If you employ a household worker, you aren’t required to withhold federal income taxes from pay. But you can choose to withhold if the worker requests it. In that case, ask the worker to fill out a Form W-4. However, you may be required to withhold Social Security and Medicare (FICA) taxes and to pay federal unemployment (FUTA) tax.

2024 and 2025 thresholds

In 2024, you must withhold and pay FICA taxes if your household worker earns cash wages of $2,700 or more (excluding the value of food and lodging). The Social Security Administration recently announced that this amount will increase to $2,800 in 2025. If you reach the threshold, all the wages (not just the excess) are subject to FICA.

However, if a nanny is under age 18 and childcare isn’t his or her principal occupation, you don’t have to withhold FICA taxes. So, if you have a part-time student babysitter, there’s no FICA tax liability.

Both an employer and a household worker may have FICA tax obligations. As an employer, you’re responsible for withholding your worker’s FICA share. In addition, you must pay a matching amount. FICA tax is divided between Social Security and Medicare. The Social Security tax rate is 6.2% for the employer and 6.2% for the worker (12.4% total). Medicare tax is 1.45% each for the employer and the worker (2.9% total).

If you want, you can pay your worker’s share of Social Security and Medicare taxes. If you do, your payments aren’t counted as additional cash wages for Social Security and Medicare purposes. However, your payments are treated as additional income to the worker for federal tax purposes, so you must include them as wages on the W-2 form that you must provide.

You also must pay FUTA tax if you pay $1,000 or more in cash wages (excluding food and lodging) to your worker in any calendar quarter. FUTA tax applies to the first $7,000 of wages paid and is only paid by the employer.

Making payments

You pay household worker obligations by increasing your quarterly estimated tax payments or increasing withholding from wages, rather than making an annual lump-sum payment.

As an employer of a household worker, you don’t have to file employment tax returns, even if you’re required to withhold or pay tax (unless you own your own business). Instead, employment taxes are reported on your tax return on Schedule H.

When you report the taxes on your return, include your employer identification number (EIN), which is not the same as your Social Security number. You must file Form SS-4 to get one.

However, if you own a business as a sole proprietor, you include the taxes for a household worker on the FUTA and FICA forms (940 and 941) you file for the business. And you use your sole proprietorship EIN to report the taxes.

Maintain detailed records

Keep related tax records for at least four years from the later of the due date of the return or the date the tax was paid. Records should include the worker’s name, address, Social Security number, employment dates, amount of wages paid, taxes withheld and copies of forms filed.

From flights to meals: A guide to business travel tax deductions

Details: Published: 06 November 2024 06 November 2024

As a business owner, you may travel to visit customers, attend conferences, check on vendors and for other purposes. Understanding which travel expenses are tax deductible can significantly affect your bottom line. Properly managing travel costs can help ensure compliance and maximize your tax savings.

Your tax home

Eligible taxpayers can deduct the ordinary and necessary expenses of business travel when away from their “tax homes.” Ordinary means common and accepted in the industry. Necessary means helpful and appropriate for the business. Expenses aren’t deductible if they’re for personal purposes, lavish or extravagant. That doesn’t mean you can’t fly first class or stay in luxury hotels. But you’ll need to show that expenses were reasonable.

Your tax home isn’t necessarily where you maintain your family home. Instead, it refers to the city or general area where your principal place of business is located. (Special rules apply to taxpayers with several places of business or no regular place of business.)

Generally, you’re considered to be traveling away from home if your duties require you to be away from your tax home for substantially longer than an ordinary day’s work and you need to get sleep or rest to meet work demands. This includes temporary work assignments. However, you aren’t permitted to deduct travel expenses in connection with an indefinite work assignment (more than a year) or one that’s realistically expected to last more than a year.

Deductible expenses

Assuming you meet these requirements, common deductible business travel expenses include:

Air, train or bus fare to the destination, plus baggage fees,
Car rental expenses or the cost of using your vehicle, plus tolls and parking,
Transportation while at the destination, such as taxis or rideshares between the airport and hotel, and to and from work locations,
Lodging,
Tips paid to hotel or restaurant workers, and
Dry cleaning / laundry.

Meal expenses are generally 50% deductible. This includes meals eaten alone. It also includes meals with others if they’re provided to business contacts, serve an ordinary and necessary business purpose, and aren’t lavish or extravagant.

Claiming deductions

Self-employed people can deduct travel expenses on Schedule C. Employees currently aren’t permitted to deduct unreimbursed business expenses, including travel expenses.

However, businesses may deduct employees’ travel expenses to the extent they provide advances or reimbursements or pay the expenses directly. Advances or reimbursements are excluded from wages (and aren’t subject to income or payroll taxes) if they’re made according to an “accountable plan.” In this case, the expenses must have a business purpose, and employees must substantiate expenses and pay back any excess advances or reimbursements.

Mixing business and pleasure

If you take a trip in the United States primarily for business, but also take some time for personal activities, you’re still permitted to deduct the total cost of airfare or other transportation to and from the destination. However, lodging and meals are only deductible for the business portion of your trip. Generally, a trip is primarily for business if you spend more time on business activities than on personal activities.

Recordkeeping

To deduct business travel expenses, you must substantiate them with adequate records — receipts, canceled checks and bills — that show the amount, date, place and nature of each expense. Receipts aren’t required for non-lodging expenses less than $75, but these expenses must still be documented in an expense report. Keep in mind that an employer may have its own substantiation policies that are stricter than the IRS requirements.

If you use your car or a company car for business travel, you can deduct your actual costs or the standard mileage rate.

For lodging, meals and incidental expenses (M&IE) — such as small fees or tips — employers can use the alternative per-diem method to simplify expense tracking. Self-employed individuals can use this method for M&IE, but not for lodging.

Under this method, taxpayers use the federal lodging and M&IE per-diem rates for the travel destination to determine reimbursement or deduction amounts. This avoids the need to keep receipts to substantiate actual costs. However, it’s still necessary to document the time, place and nature of expenses.

There’s also an optional high-low substantiation method that allows a taxpayer to use two per-diem rates for business travel: one for designated high-cost localities and a lower rate for other localities.

The business travel deduction rules can be complicated. In addition, there are special rules for international travel and travel with your spouse or other family members. If you’re uncertain about the tax treatment of your expenses, contact us.

You don’t have to be in business to deduct certain vehicle expenses

Details: Published: 31 October 2024 31 October 2024

When you think about tax deductions for vehicle-related expenses, business driving may come to mind. However, businesses aren’t the only taxpayers that can deduct driving expenses on their returns. Individuals may also be able to deduct them in certain circumstances. Unfortunately, under current law, you may be unable to deduct as much as you could years ago.

How the TCJA changed deductions

For years before 2018, miles driven for business, moving, medical and charitable purposes were potentially deductible. For 2018 through 2025, business and moving miles are deductible only in much more limited circumstances. The changes resulted from the Tax Cuts and Jobs Act (TCJA), which could also affect your tax benefit from medical and charitable miles.

Before 2018, if you were an employee, you potentially could deduct business mileage not reimbursed by your employer as a miscellaneous itemized deduction. The deduction was subject to a 2% of adjusted gross income (AGI) floor, meaning that mileage was deductible only to the extent that your total miscellaneous itemized deductions for the year exceeded 2% of your AGI. However, for 2018 through 2025, you can’t deduct the mileage regardless of your AGI. Why? The TCJA suspends all miscellaneous itemized deductions subject to the 2% floor.

If you’re self-employed, business mileage can still be deducted from self-employment income. It’s not subject to the 2% floor and is still deductible for 2018 through 2025, as long as it otherwise qualifies.

Medical and moving

Miles driven for a work-related move before 2018 were generally deductible “above the line” (itemizing wasn’t required to claim the deduction). However, for 2018 through 2025, under the TCJA, moving expenses are deductible only for active-duty military members.

If you itemize, miles driven for health-care-related purposes are deductible as part of the medical expense deduction. For example, you can include in medical expenses the amounts paid when you use a car to travel to doctors’ appointments. For 2024, medical expenses are deductible to the extent they exceed 7.5% of your AGI.

The limits for deducting expenses for charitable miles driven are set by law and don’t change yearly based on inflation. But keep in mind that the charitable driving deduction can only be claimed if you itemize. For 2018 through 2025, the standard deduction has nearly doubled, so not as many taxpayers are itemizing. Depending on your total itemized deductions, you might be better off claiming the standard deduction, in which case you’ll get no tax benefit from your charitable miles (or from your medical miles, even if you exceed the AGI floor).

Rates depend on the trip

Rather than keeping track of your actual vehicle expenses, you can use a standard mileage rate to compute your deductions. The 2024 rates vary depending on the purpose:

Business, 67 cents per mile.
Medical, 21 cents per mile.
Moving for active-duty military, 21 cents per mile.
Charitable, 14 cents per mile.

In addition to deductions based on the standard mileage rate, you may deduct related parking fees and tolls. There are also substantiation requirements, which include tracking miles driven.

How can you build a golden nest egg if you’re self-employed?

Details: Published: 30 October 2024 30 October 2024

If you own a small business with no employees (other than your spouse) and want to set up a retirement plan, consider a solo 401(k) plan. This is also an option for self-employed individuals or business owners who wish to upgrade from a SIMPLE IRA or Simplified Employee Pension (SEP) plan.

A solo 401(k), also known as an individual 401(k), may offer advantages in terms of contributions, tax savings and investment options. These accounts are geared toward self-employed individuals, including sole proprietors, owners of single-member limited liability companies, consultants and other one-person businesses.

How much can you contribute?

You can make large annual tax-deductible contributions to a solo 401(k) plan. For 2024, you can make an “elective deferral contribution” of up to $23,000 of your net self-employment (SE) income to a solo 401(k). The elective deferral contribution limit increases to $30,500 if you’ll be age 50 or older as of December 31, 2024. The larger $30,500 figure includes an extra $7,500 catch-up contribution that’s allowed for older owners.

On top of your elective deferral contribution, an additional contribution of up to 20% of your net SE income is permitted for a solo 401(k). This is called an “employer contribution,” though there’s technically no employer when you’re self-employed. For purposes of calculating the employer contribution, your net SE income isn’t reduced by your elective deferral contribution.

For the 2024 tax year, the combined elective deferral and employer contributions can’t exceed:

$69,000 ($76,500 if you’ll be 50 or older as of December 31, 2024), or
100% of your net SE income.

Net SE income equals the net profit shown on Form 1040, Schedule C, E or F for the business, minus the deduction for 50% of self-employment tax attributable to the business.

What are the advantages and disadvantages?

Besides the ability to make significant deductible contributions, another solo 401(k) advantage is that contributions are discretionary. If cash is tight, you can contribute a small amount or nothing.

In addition, you can borrow from your solo 401(k) account, assuming the plan document permits it. The maximum loan amount is 50% of the account balance or $50,000, whichever is less. Some other plan options, including SEPs, don’t allow loans. This feature can be valuable if you need access to funds for business opportunities or emergencies.

The biggest downside to solo 401(k)s is their administrative complexity. Significant upfront paperwork and ongoing administrative efforts are required, including adopting a written plan document and arranging how and when elective deferral contributions will be collected and paid into the owner’s account. Also, once your account balance exceeds $250,000, you must file Form 5500-EZ with the IRS annually.

You can’t have a solo 401(k) if your business has one or more employees. Instead, you must have a multi-participant 401(k) with all the resulting complications. The tax rules may require you to make contributions for those employees. However, there are a few important loopholes. You can contribute to a plan if your spouse is a part-time or full-time employee. You can also exclude employees who are under 21 and part-time employees who haven’t worked at least 1,000 hours during any 12-month period.

Who’s the best candidate for this plan?

For a one-person business, a solo 401(k) can be a smart retirement plan choice if:

You want to make large annual deductible contributions and have the money,
You have substantial net SE income, and
You’re 50 or older and can take advantage of the extra catch-up contribution.

Before establishing a solo 401(k), weigh the pros and cons of other retirement plans — especially if you’re 50 or older. Solo 401(k)s aren’t simple, but they can allow you to make substantial and deductible contributions to a retirement nest egg.

Employers: In 2025, the Social Security wage base is going up

Details: Published: 22 October 2024 22 October 2024

As we approach 2025, changes are coming to the Social Security wage base. The Social Security Administration recently announced that the wage base for computing Social Security tax will increase to $176,100 for 2025 (up from $168,600 for 2024). Wages and self-employment income above this amount aren’t subject to Social Security tax.

If your business has employees, you may need to budget for additional payroll costs, especially if you have many high earners.

Social Security basics

The Federal Insurance Contributions Act (FICA) imposes two taxes on employers, employees and self-employed workers. One is for Old Age, Survivors and Disability Insurance, which is commonly known as the Social Security tax, and the other is for Hospital Insurance, which is commonly known as the Medicare tax.

A maximum amount of compensation is subject to the Social Security tax, but there’s no maximum for Medicare tax. For 2025, the FICA tax rate for employers will be 7.65% — 6.2% for Social Security and 1.45% for Medicare (the same as in 2024).

Updates for 2025

History of the wage base

When the government introduced the Social Security payroll tax in 1937, the wage base was $3,000. It remained that amount through 1950. As the U.S. economy grew and wages began to rise, the wage base needed to be adjusted to ensure that the Social Security system continued to collect sufficient revenue. By 1980, it had risen to $25,900. Twenty years later it had increased to $76,200 and by 2020, it was $137,700. Inflation and wage growth were key factors in these adjustments.

Employees with more than one employer

You may have questions about employees who work for your business and have second jobs. Those employees would have taxes withheld from two different employers. Can the employees ask you to stop withholding Social Security tax once they reach the wage base threshold? The answer is no. Each employer must withhold Social Security taxes from an employee’s wages, even if the combined withholding exceeds the maximum amount that can be imposed for the year. Fortunately, the employees will get a credit on their tax returns for any excess withheld.
