Tax Services for the Self-Employed and Freelancers
Schedule C, self-employment tax, quarterly estimates and the deductions that get missed — handled properly, for people nobody withholds anything for.
Nobody is withholding anything for you
That single fact drives almost everything that goes wrong for self-employed people at tax time. An employee has income tax and payroll tax taken out before they ever see the money. A freelancer, contractor or gig worker receives the gross amount, and the entire obligation — income tax, plus self-employment tax on top of it — arrives later as a bill.
Self-employment tax is the part that catches people out. It covers both halves of Social Security and Medicare, the employee half and the employer half, because when you work for yourself you are both. It applies to net business profit and it applies before the standard deduction touches anything. People who have always been employees routinely budget for their income tax bracket and are then surprised by a liability substantially larger than they planned for.
This is not a reason to avoid self-employment. It is a reason to know the number during the year rather than discovering it in April.
Who this is for
- Freelancers and consultants invoicing clients directly
- Gig and platform workers — delivery, rideshare, marketplace and app-based work
- Independent tradespeople working under 1099s
- Anyone running a side business alongside a W-2 job
- Single-member LLC owners still filing on Schedule C
- People who received a 1099 for the first time and are not sure what it means
The most common of these — and the one most often handled badly — is the last two combined: a salaried employee with a side business that has grown past the point where it can be ignored.
What we do
- Schedule C preparation — business income and expenses reported correctly
- Self-employment tax calculated, including the deduction available against it
- Quarterly estimated payments set from real projections rather than last year’s figure
- Deduction review: vehicle and mileage, home office, equipment, supplies, insurance, retirement contributions
- Bookkeeping, where the records are not currently good enough to support the return
- Entity advice — whether an LLC or S-Corp election is justified yet, and honestly when it is not
- Federal and South Carolina returns prepared together
The deductions people actually miss
Most missed deductions are not exotic. They are ordinary business costs that were never recorded, because nobody was keeping records at the time they were incurred.
Vehicle and mileage
Usually the largest single deduction available to a mobile self-employed person, and the most frequently lost. Business use of a vehicle is deductible, calculated either by mileage or by actual costs — but it requires contemporaneous records. A figure reconstructed from memory in April is neither accurate nor defensible if questioned.
Home office
Available where a space is used regularly and exclusively for the business. "Exclusively" is the word that disqualifies most claims — a dining table that is also a desk does not qualify. Where it does apply, it is straightforward and legitimate.
Retirement contributions
Self-employed people have access to retirement vehicles with contribution limits well above an ordinary IRA, and contributions reduce taxable income. This is one of the few remaining levers that can be pulled after the year has ended, depending on the plan type.
The self-employment tax deduction
A portion of self-employment tax is itself deductible against income tax. It is automatic on a correctly prepared return and quietly missed on an incorrectly prepared one.
When it is worth changing structure
The question we are asked most is whether to form an LLC or elect S-Corp treatment. The honest answer is that it depends on profit, and that below a certain level the answer is no.
An LLC provides liability separation but does not by itself change how a single-owner business is taxed — a single-member LLC still files on Schedule C by default. The tax question is the S-Corp election, which can reduce self-employment tax on the portion of profit taken as distribution rather than salary. It also requires running payroll, paying yourself a defensible reasonable salary, and filing a separate business return.
Those obligations cost money and time. Below the point where the saving exceeds them, electing is a net loss. Above it, the saving can be substantial. That threshold is worth checking annually rather than assumed once and forgotten.
Self-employment tax questions
Do I have to pay quarterly estimated taxes?
Generally yes if you expect to owe more than a threshold amount when you file and nothing is being withheld on your behalf. Skipping them does not defer the tax — it adds underpayment penalties on top of it. The exception is where you also have a W-2 job and can increase withholding there to cover the business liability, which is sometimes simpler than making four separate payments.
What is self-employment tax and why is it so high?
It covers both the employee and employer halves of Social Security and Medicare. An employee pays one half and their employer pays the other; when you work for yourself you pay both. It applies to net profit, separately from and in addition to income tax, which is why the total bill is larger than people expect from their bracket alone.
I got a 1099 for the first time. What do I do?
It means you were paid as a contractor rather than an employee, so the income is reported as business income on Schedule C and carries self-employment tax. You can deduct legitimate business expenses against it, which is why keeping records from the start matters. If this is likely to continue, quarterly estimates probably apply going forward.
Do I need to report income if I did not receive a 1099?
Yes. The obligation attaches to the income, not to whether anyone issued you a form. Cash income, payments below a reporting threshold and platform income that generated no 1099 are all reportable in the same way.
Can I deduct my phone, internet and laptop?
The business-use portion, yes. The complication is that these are almost always mixed-use, so the deduction is a proportion rather than the whole cost, and that proportion should be reasonable and supportable rather than convenient.
Should I form an LLC?
For liability separation, often. For tax reasons, an LLC alone changes nothing for a single owner — a single-member LLC is still taxed on Schedule C by default. The tax decision is whether to elect S-Corp treatment, and that depends on how much the business actually nets.
