Fiscal year

The 12-month period a business uses for accounting and tax reporting — often the calendar year (January through December), but it can be any 12-month span a business chooses.

§ 01 · In plain terms

What fiscal year means.

A fiscal year is the 12-month period a business uses for its accounting and tax reporting. For many businesses it is the calendar year — January 1 through December 31 — but it doesn’t have to be. A fiscal year can be any 12-month span: a retailer might end its year on January 31, after the holiday rush has fully settled, so the busiest season falls inside one clean reporting period.

The fiscal year sets the rhythm of the books: it determines when the year-end close happens, when annual financial statements are produced, and when tax returns come due. Once chosen, it’s the frame every annual report is built in.

§ 02 · Why it matters

Why the choice shapes your reporting.

Picking a fiscal year that matches how the business actually operates makes the numbers easier to read: a seasonal business that ends its year right after its peak gets a cleaner picture of a full cycle than one split awkwardly across two calendar years. The choice also fixes your deadlines — when the books must be closed and when returns are due — so it shapes the whole annual workload.

TechBrot keeps your books and closes aligned to whatever fiscal year you’re on, so each period ties out and the year-end package is ready on schedule. The actual fiscal-year (tax-year) election — whether you may use a non-calendar year, and how to elect or change it — is a tax matter confirmed with your CPA or EA.

§ 03 · The rule

What the IRS says about a fiscal year.

The definition

IRS Publication 538 (Rev. January 2022) draws the line: “A calendar year is 12 consecutive months beginning on January 1st and ending on December 31st.” and “A fiscal year is 12 consecutive months ending on the last day of any month except December 31st.”

It is a tax year too

The same publication says “You must use a tax year to figure your taxable income,” and that “A tax year is an annual accounting period for keeping records and reporting income and expenses.” Whether a business may use a fiscal year, and how to adopt or change one, is a tax question for your CPA or EA.

§ 04 · Worked example

A fiscal year in QuickBooks: a worked example.

Illustrative, not a client file.

  1. 01

    The business

    A garden-supply retailer sells most of its stock from March to June and ends its year on September 30, after the season has settled and the year-end inventory count is done.

  2. 02

    The setting

    In QuickBooks Online the first month of the fiscal year is a company setting (under Account and settings, Advanced, Accounting). Set to October, “This fiscal year” on the profit and loss runs October 1 to September 30, so the spring peak and the autumn wind-down sit in one report.

  3. 03

    Left on January

    If the setting stays on January, the annual report cuts the selling season in two and every year-to-year comparison puts half a cycle against half a cycle. Nothing in the data is wrong; the frame is.

§ 05 · In QuickBooks

How the fiscal year goes wrong in QuickBooks.

01

A setting that never matched the business

The file runs on January because that was the default, while the owner, the lender and the return all think in a different year.

02

Two settings that disagree

QuickBooks keeps the fiscal year and the income tax year as separate settings, so they can differ without anyone choosing it. Confirm both with your CPA.

03

Changed after the books were closed

Moving the first month once periods are closed shifts where reports divide the year, and last year's reports no longer line up with this year's. Change it with the closing date and your CPA's word.

04

Year-end done on the wrong date

Adjusting entries, the year-end package and the closing date belong to the fiscal year-end, not December 31 by habit. QuickBooks year-end close is the work of getting that right; monthly bookkeeping keeps each close aligned to it.

§ 06 · A common confusion

Fiscal year vs. calendar year.

A calendar year always runs January 1 to December 31. A fiscal year is any 12-month reporting period a business uses — which may be the calendar year, or may end on a different date (a fiscal year ending January 31, June 30, and so on). Every calendar year is a fiscal year; not every fiscal year is the calendar year.

Which one you may use, and the fiscal-year or tax-year election, is confirmed with your CPA — TechBrot is a bookkeeping and advisory firm and does not advise on or file the tax-year election. We keep the books accurate on whichever year you’re on.
