When you work for someone else, the office is free. The rent, the electricity, the fast internet, the chair that doesn’t wreck your back — all of it is someone else’s line item. The moment you go solo and work from home, those costs quietly become yours. You’re now running a small office out of your flat, and you’re paying for it out of the same account that buys your groceries.
The good news is that Indian tax law recognises this. If you earn business or professional income — which is what most freelancers and sole proprietors do — the expenses you incur “wholly and exclusively” for that work are deductible against your income under Section 37 of the Income Tax Act. A home office generates a surprising number of those expenses. The problem is that they’re tangled up with personal spending, so most people never claim them properly.
First, know which regime you’re in
A quick but important caveat: these deductions apply when you’re taxed on your actual business profits — you tally up income, subtract expenses, and pay tax on what’s left. That’s the default for professional and business income.
If instead you opt for presumptive taxation under Section 44ADA (available to many professionals with gross receipts under the prescribed limit), you declare a flat 50% of your receipts as profit and the other 50% is deemed to cover all your expenses. In that case you don’t itemise a home office deduction separately — it’s already baked into the presumption. So before you track a single rupee, decide which regime you’re using, because it changes whether any of this is worth doing.
The rest of this post assumes you’re on actual-profit taxation.
The apportionment principle
Here’s the core idea, and it’s the same one that runs through every home office deduction: you can only claim the business portion of a shared expense.
Your flat isn’t 100% an office. It’s mostly a home that you also work in. So you can’t deduct your entire rent or your entire electricity bill — but you can deduct the slice attributable to work. The standard, defensible way to work out that slice is by floor area:
Business % = (area used for work) ÷ (total area of the home)
If you work from a 120 sq ft room in a 1,000 sq ft flat, roughly 12% of your shared home costs are attributable to the business. Use that same percentage consistently across rent, electricity, and other whole-home expenses. Consistency is what makes it credible if anyone ever asks.
Be honest about the space. A dedicated room used only for work is the cleanest case. The corner of your bedroom is harder to defend, and “the whole flat because I take calls everywhere” won’t survive scrutiny. Pick a reasonable, genuinely work-used area and stick to it.
What you can actually claim
Rent. The business percentage of your rent is deductible. If you pay ₹40,000 a month and your work area is 12% of the flat, that’s ₹4,800 a month, or ₹57,600 a year. Keep the rent agreement and proof of payment (bank transfers, not cash, wherever possible).
Electricity and utilities. The same percentage of your power bill covers the lights, the fan or AC in your workspace, and keeping your machine running. Water and other utilities follow the same logic if they’re genuinely part of the work environment.
Internet and phone. These are rarely a clean 100% business expense — you also stream shows and message friends on the same connection. Apportion by realistic usage. A common approach is a reasonable business-use percentage (say 70–80% if your work is internet-heavy) applied to the bill. If you can get a dedicated business line, even better — that’s fully deductible.
Equipment and furniture. Your laptop, monitor, desk, and office chair are business assets. Larger items are typically capitalised and depreciated rather than expensed all at once — you claim depreciation each year under the prescribed rates rather than the full cost in year one. Smaller consumables (a keyboard, a webcam, stationery) can usually be expensed directly.
Repairs and maintenance. The business share of repairs to the workspace, and maintenance of your equipment, is deductible on the same apportionment basis.
Professional software and subscriptions. Tools you use for the work — design software, accounting apps, cloud storage for client files — are generally fully deductible, since they’re used wholly for the business.
The rule that makes all of this work: records
None of these deductions mean anything if you can’t substantiate them. The tax department doesn’t take your word for it, and reconstructing a year of expenses from memory in July is miserable and inaccurate.
So build the paper trail as you go:
- Keep every bill and invoice — rent, electricity, internet, equipment — ideally digitally, so nothing fades or gets lost.
- Pay from your business account. This is the single biggest thing you can do. When work expenses flow through a separate account, your deduction list practically writes itself, and the line between business and personal spending stays clean. (If you haven’t separated your accounts yet, that’s the prerequisite to all of this.)
- Write down your floor-area calculation once, with the numbers, and reuse it every year until the space changes.
- Note the business-use percentage you chose for mixed items like internet, and be ready to justify it.
Don’t get greedy
The fastest way to turn a legitimate deduction into a problem is to overreach. Claiming your entire rent, deducting a “home office” that’s really the family living room, or expensing a personal laptop as a business asset — these are the things that draw scrutiny and can unravel the genuine claims alongside them.
The goal isn’t to deduct as much as you can dream up. It’s to claim what you’re genuinely entitled to, cleanly and defensibly, so that your taxable income reflects what you actually earned after the real cost of running your business. Working from home has a real cost. You’re already paying it — you may as well account for it properly.
