  • What to Do Before December 31: A Freelancer’s Year-End Tax List

    Most of what you read about year-end tax moves is written for people with employers. For a freelancer the list is shorter than it looks — and one item on it is invisible, cannot be fixed in April, and costs more than everything else combined. This is what actually expires on December 31, 2026, and…

  • Self-Employed Health Insurance Deduction Calculator (2026)

    Your health insurance premiums are deductible, but not all of them, and not always. Two limits decide how much — one tied to what the business earned, one tied to whether a job was available to you. This calculator applies both. Everything below explains the two limits, and what happens to the part you cannot…

  • Self-Employment Tax Calculator With W-2 Income

    Most self-employment tax calculators ask for one number. That works until you also have a job, at which point the answer they give you can be three times too high. This one asks for your W-2 wages because they change the answer. Everything below explains why. The number most calculators get wrong Self-employment tax is…

  • Quarterly Estimated Tax Calculator for Freelancers (2026)

    Four dates, and a number you have to work out yourself. The IRS does not send a bill for estimated taxes — it expects you to know what to send and to send it on time. This calculator works out the safe harbor for 2026 and splits it into the four payments. Everything below explains…

  • Schedule C Business Codes for Freelancers: Box B, Decoded

    Box B on Schedule C wants a six-digit number, and the form tells you almost nothing about how to pick it. The instruction reads: enter the six-digit code from the Principal Business or Professional Activity Codes chart at the end of these instructions. That chart is four pages of dense columns organised by industry, not…

  • Form 8829, Line by Line: The Home Office Form Explained

    Form 8829 is one page and 44 lines, and it exists to turn what your home costs into one number on Schedule C line 30. Most of those lines are arithmetic. Four of them decide the answer. You only need this form if you are using the actual expense method. The simplified method — square…

  • Nevada LLC for Freelancers: What It Really Costs a Year

    $425 in year one, then $350 every year after. That is what Nevada’s own statutes charge a single-member LLC, and it is three separate fees rather than the single number formation ads quote. If you live anywhere else, all of it sits on top of what your home state already charges. Nevada’s missing income tax…

  • App Developer Taxes: Your Payout Is Not Your Income

    Apple deposits $27,200 and you earned $32,000. The $4,800 gap is Apple’s commission, and both numbers belong on Schedule C — the $32,000 as gross receipts on line 1, the $4,800 as a deduction below it. Report only the deposit and your return will not match the 1099-K Apple already filed. Same profit, wrong paperwork,…

  • Creator Write-Offs: Camera Yes, Clothes No

    A camera comes off in full. The shirt you wore in the video almost never does. Creator spending runs through the same test as every trade, but lands in stranger places, because much of what you buy is also just life. Gear is the easy part Cameras, lenses, lights, microphones, a machine fast enough to…

  • Taxes for YouTubers, Streamers, and Influencers

    A creator’s money arrives through six different pipes, and only some of them send a form. Ad revenue, brand deals, affiliate links, fan funding, merchandise, and free product. All six are taxable income. The one that surprises people is the last one. A $900 camera sent to you for a review is $900 of income,…
