Schedule E estimator

What Schedule E is, and why April hurts

If you own rental property as an individual, you report its income and expenses on Schedule E of your federal return — Supplemental Income and Loss. One column per property, income at the top, expense categories beneath, net result at the bottom. The form itself is not complicated. What makes it painful is that it asks you, in April, to produce a year's worth of categorised spending you did not categorise at the time.

The estimator above mirrors the expense categories the form uses, so you can see roughly where you land before you sit down with a preparer. It is an estimate. It is not tax advice, it does not know your situation, and it deliberately does not try to compute tax owed.

The categories that catch people out

Repairs versus improvements. The single most consequential distinction on the form. A repair keeps the property in its existing condition and is generally deductible in the year you pay it. An improvement betters the property, restores it, or adapts it to a new use, and is generally capitalised and depreciated over years. Replacing a broken window pane is usually a repair. Replacing every window in the building is usually an improvement. The line is genuinely blurry and there are safe harbours that can change the answer, which is exactly why it is worth flagging to a preparer rather than guessing.

Mortgage interest, not the mortgage payment. Only the interest portion is an expense. The principal portion is not deductible — it is you buying the asset. Your lender's year-end statement splits this for you.

Depreciation is not optional. The tax code reduces your basis by the depreciation you were allowed to take, whether or not you actually took it, so skipping it defers nothing — you still face recapture on it when you sell. Missed years can be caught up, but through a formal accounting-method change on Form 3115, not by claiming extra the following year. See IRS Publication 527. The building depreciates, the land does not, which means you need the split between them.

Your own labour is not an expense. The weekend you spent painting is not deductible. Materials are; your time is not.

Keeping it from being a year-end reconstruction

Most of the pain is avoidable with one habit: categorise each expense when it happens rather than in April. A separate bank account per property, or at minimum a single account used only for rentals, removes the hardest part — separating a property expense from a personal one eleven months after the fact from a bank line that just says the name of a hardware store.

Keep receipts for anything you will later have to defend as a repair rather than an improvement, and keep the closing statement from purchase: it establishes the basis every future depreciation calculation depends on.

What this estimator will not tell you

It will not tell you your tax. Net rental income flows into your return alongside everything else, and what happens next depends on your bracket, your other income, whether your activity counts as passive, whether you qualify as a real estate professional, and whether a loss is currently deductible or suspended. Those are real questions with real money attached, and they are worth a preparer. What the estimator gives you is the number to walk in with, and a sense of which expense line is doing the heavy lifting.
