Fixed asset depreciation software built for QuickBooks Online
Book and tax depreciation side by side on one asset register. Finlens drafts the monthly entry, you approve it, it posts to QuickBooks. MACRS is applied for you. Section 179 and bonus are modeled so you can choose.

Where the fixed asset register actually breaks
The calculation is rarely the problem. The problem is that book and tax live in different places, maintained by different people, reconciled once a year.
- One workbook, one owner
The person who built the tabs is the only person who can close with it.
- Book lives in QuickBooks, tax lives in a file
Two registers, maintained twice, reconciled once a year under pressure.
- MACRS life and convention looked up by hand
Every asset, every time, out of Publication 946.
- Section 179 and bonus decided at year end
By then the placed-in-service dates are already locked.
- Disposals discovered in the audit
The asset left the building, the schedule kept depreciating it.
- The M-1 difference is a plug
Nobody can trace it back to an asset.
- One register, everyone reads it
Lives against your QuickBooks chart of accounts, not in someone's Downloads folder.
- Book and tax on the same asset record
Entered once, calculated twice, never drifts apart.
- Life, method and convention applied automatically
From the asset class you pick. Half-year or mid-quarter resolved for you.
- Elections modeled before you commit
See the tax effect of Section 179 against bonus against straight MACRS.
- Disposals handled on the asset record
Gain or loss calculated, depreciation stops the right day.
- Every difference traces to a line
The M-1 column is the sum of named assets, not a plug.

Book depreciation and tax depreciation are not the same number
A working summary for controllers and firm partners. Four minutes, no jargon you would not use with a client.
Book vs tax
Under ASC 360, book depreciation allocates the cost of a fixed asset over the periods it helps produce revenue. You choose a useful life and a method that reflects how the asset is consumed. For most firms that means straight-line over five to fifteen years with no salvage value, and the result is a steady monthly expense that keeps the balance sheet honest.
Tax depreciation answers a different question: how much deduction does the IRS allow this year? That is governed by IRC §167 and §168 and documented in Publication 946. The method is prescribed rather than chosen, and it is front-loaded by design. The two numbers are supposed to differ. The job is to carry both for every asset and to know, line by line, why the difference exists. That difference is what gets reconciled on Schedule M-1 (or M-3) when the return is prepared.
MACRS lives and conventions
MACRS assigns every asset to a recovery class. Most equipment lands in the 5-year class (computers, vehicles, office machinery) or the 7-year class (manufacturing equipment, furniture, and anything not assigned elsewhere). Land improvements are 15-year. Nonresidential buildings are recovered over 39 years, straight-line, and residential rental property over 27.5.
The convention decides how much of the first year you get. The default is half-year: every asset placed in service during the year is treated as if it arrived on July 1. If more than 40 percent of the year's depreciable basis is placed in service in the last quarter, the whole year flips to mid-quarter and every asset is recomputed. Real property always uses mid-month. The convention is tested at year end, which is exactly when a hand-built register is least likely to be recalculated.
Section 179 in 2026
Section 179 lets you expense qualifying property in the year it is placed in service instead of depreciating it. The deduction is also capped at the business's taxable income for the year; anything above that carries forward. It is elected per asset, so you can take it on some purchases and leave others on MACRS, which makes it a modeling question rather than a year-end checkbox.
| Section 179 | 2025 | 2026 |
|---|---|---|
| Deduction ceiling | $2,500,000 | $2,560,000 |
| Phase-out starts above | $4,000,000 | $4,090,000 |

Bonus and the acquisition date
Bonus depreciation now turns on when the asset was acquired, not only when it was placed in service.
Property acquired and placed in service after January 19, 2025 qualifies for the 100 percent allowance restored by P.L. 119-21. Property acquired before January 20, 2025 stays on the old phase-down, even if it was placed in service later. Two near-identical machines bought three weeks apart are treated differently, and a register keyed only on the in-service date will not catch it.
Unlike Section 179, bonus depreciation has no dollar ceiling and no taxable-income cap, and it applies automatically unless you elect out by asset class. It also covers qualified improvement property, the interior improvements to a nonresidential building, which is why the tenant buildout in the register above is written off in full for tax in year one while staying on a 15-year straight-line book schedule.
Disposals and partial years
When an asset is sold, scrapped or traded in, three things have to happen on the same day: depreciation stops, cost and accumulated depreciation come off the balance sheet, and the gain or loss is calculated against net book value. On the tax side the half-year convention still applies to the year of disposal, and gain up to the depreciation already taken is recaptured as ordinary income under §1245. Real property follows the narrower §1250 rules instead.
The most common failure here is not a wrong calculation but a missing one. The asset leaves the building and the schedule keeps running for another two years, until an auditor asks to see it.
What QuickBooks does
QuickBooks Online Advanced keeps an asset list and posts book depreciation on the first of each month. No plan computes MACRS, Section 179 or bonus, or carries the book-to-tax difference per asset. The comparison above has the row-by-row view.

Illustrative. Book is straight-line from the month placed in service. Tax uses the MACRS 7-year GDS half-year rates from Pub 946 Table A-1 (14.29%, 24.49%, 17.49%). Over the full life both books total $248,000; only the timing differs, and that timing is the M-1 difference. Finlens runs this for every asset in the register, every month.
How Finlens tracks a fixed asset from purchase to disposal
Finlens follows the asset through its whole life. Your team touches it once, at approval.
Finds the asset
Reads QuickBooks for purchases above your capitalization threshold and proposes the asset record, with the source bill attached.
Builds both books
Assigns the book life and MACRS class, resolves the convention, and models Section 179 and bonus before you commit.
Drafts the entry
Every month, per asset, book and tax, with the source transaction on every line of the journal.
You sign off
Nothing posts to QuickBooks until a reviewer approves. Disposals stop depreciation on the right day and draft the removal entry.
Frequently asked questions
The questions that come up on every demo call about depreciation and QuickBooks Online.
Only on QuickBooks Online Advanced, and only for book depreciation. Advanced includes a fixed asset feature that records assets and posts the monthly depreciation entry. Simple Start, Essentials and Plus have no fixed asset feature, so depreciation on those plans is a recurring manual journal entry.
No. No QuickBooks Online plan calculates MACRS recovery periods, half-year or mid-quarter conventions, Section 179 or bonus depreciation. Tax depreciation has to be computed outside QuickBooks, which is what Finlens does, and then reconciled to book through Schedule M-1.
No. Finlens keeps the asset register and both depreciation schedules itself, then posts the approved journal entry to QuickBooks through the standard API. It works with any QuickBooks Online plan that supports journal entries.
When an asset is capitalized, Finlens classifies it, checks the acquisition and in-service dates against the bonus rules, and shows the year-one effect of straight MACRS, bonus and Section 179 side by side. You pick Section 179 per asset and the bonus election by property class. The tax schedule is rebuilt from that choice and the book schedule is untouched.
You record the disposal on the asset record with the date and proceeds. Finlens stops depreciation on both books from that date, applies the tax convention for the disposal year, calculates the gain or loss against net book value, and drafts the removal entry for approval.
Yes. Import your current register as a spreadsheet with cost, in-service date, method, life and accumulated depreciation for each book. Finlens picks up each schedule from its current position, so historic entries are not reposted.
