How Do You Estimate Taxes in Your First Year of Self-Employment?
Starting a business or freelance practice comes with a tax wrinkle that’s easy to overlook in the excitement of the first client or sale: there’s no prior year of self-employment income to use as a baseline for estimated payments.
The short answer
Without a prior year of self-employment income to reference, first-year estimated taxes generally have to be built from a rough income and expense projection, then revised as actual numbers come in throughout the year. Because the first year is the hardest to estimate accurately, treating the projection as a starting guess rather than a fixed number, and adjusting each subsequent payment, tends to work better than trying to get it exactly right from the outset.
Why the first year is different
Estimated tax systems are built around the idea of paying tax as income is earned throughout the year, which for most established self-employed people means looking at the prior year’s return as a reasonable starting point. Someone in their first year of self-employment doesn’t have that reference point — there’s no completed Schedule C from the year before showing what a typical quarter looks like. That leaves a new business relying on a forecast rather than a track record, which naturally makes the numbers less reliable at the outset.
Building a rough projection
A reasonable starting point is a conservative estimate of revenue for the year, minus expected business expenses, based on whatever information is available — a business plan, comparable rates in the field, or early client agreements already in hand. It doesn’t need to be precise; it needs to be a reasonable placeholder that can be revised. Some new business owners find it easier to project income month by month rather than as a single annual figure, since early months often look different from a business that’s ramped up.
Revising the estimate as the year unfolds
Because estimated payments are made quarterly rather than once a year, a first-year projection doesn’t have to be right on day one — it just has to be updated as real numbers replace guesses. After the first quarter or two of actual income and expenses, it’s worth revisiting the original projection and adjusting later payments to reflect what’s actually happening, rather than continuing to pay based on a guess made before the business had any operating history. This mirrors the approach useful for anyone dealing with irregular freelance income, where the estimate is treated as a living number rather than a fixed target.
Accounting for the self-employment tax piece
A projection built only around income tax risks understating what’s owed, since self-employment income is generally also subject to self-employment tax, which covers the portion of Social Security and Medicare contributions that an employer would otherwise split with an employee. New business owners coming from a W-2 job sometimes forget to build this second layer into their estimate, since it wasn’t visible as a separate line item when it was withheld automatically from a paycheck. Leaving it out of a first-year projection is one of the more common ways an estimate ends up too low.
The bottom line
A first-year estimate for a new business is inherently a rougher guess than one built from a prior year’s actual results, and that’s fine as long as it’s treated as a starting point rather than a fixed answer. Checking in each quarter and adjusting the next payment based on what’s actually come in keeps the estimate honest as the business finds its footing.
