№ 001 — Taxes

The IRS expects a check four times a year. Stop guessing.

Post recalculates what you owe every time money lands — your state, your filing status, your real deductions — so the quarterly deadline is a number, not a panic.

№ 002 — Quarterly estimates

What to set aside this month.

Not a flat 30%. Federal, self-employment, and state, calculated month by month against what you actually earned — so the number you save is the number you'll owe.

Try it — what do you make a month?

Estimates, not tax advice — your write-offs and credits shift every line. Self-employment tax is usually the surprise: it’s often bigger than income tax.

The IRS’s cut of that
≈ $1,762/mo isn’t yours.

Federal $7,581 + self-employment $13,564 a year — an effective 22% before state tax.

Per-user numbers are planning estimates, generated by an engine co-built with accountants. Review with your CPA before filing or paying. Post is not a tax preparer or accounting firm.

Taxes, done your way

The work is already done. You just pick who finishes it.

When tax time comes, you get a full draft of your return — every number filled in. From there, it’s your call.

Your CPA

Hand it to your accountant.

  • Invite them as a collaborator — free seat
  • They see everything in accounting language
  • Notes, questions, and adjusting entries all in one place

№ 004 — At tax time

Tax time arrives with the work already done.

A full draft return — Schedule C, every number filled in from the year you already tracked. File it yourself with the step-by-step guide, hand your CPA a package they'll thank you for, or add the CPA-filed return (get a quote). Your call, zero re-typing.

№ 005 — S-corps

Run an S-corp? We speak K-1.

Already elected — or wondering if you should be? Post handles the parts that make an S-corp a headache. Planning estimates; confirm the specifics with your CPA.

01
Should you elect?

Post runs the S-corp election math against your real income, so you can see whether electing would actually save you money before you file the paperwork.

02
A defensible salary

Set a reasonable-compensation number you can stand behind — benchmarked, so it holds up if the IRS ever asks.

03
Payroll vs. distributions

Post splits your reasonable salary from owner distributions and tracks the payroll taxes on each — the whole point of the election, handled.

04
A K-1 at year end

Export a clean K-1 package — totals, a schedule, and a draft form — ready to hand your CPA or drop into your filing.

State by state

Creator taxes in your state.

Brackets, quarterly schedules, and a worked example for all fifty states and D.C. — every number computed by the same engine that runs the Post dashboard.

Know what you owe.
