Income Tax for Security Agencies in India 2026: ITR, Business Code, Presumptive Tax, GST & Expenses

Security agencies are labour-intensive businesses with large payroll flows, site-wise billing and statutory compliance. Gross receipts should not be reduced to the agency’s margin unless the legal arrangement genuinely supports agency accounting.

Finin2min answer

The activity is ordinarily a business when carried on independently and systematically for profit. Taxable business profit is normally gross receipts/turnover less admissible business expenditure, subject to the Act.

AY 2026-27 code: 16015 — Investigation and security services.

For AY 2026-27, section 44AD may be available to an eligible resident individual, HUF or partnership firm other than LLP if the activity is an eligible business and turnover stays within the statutory limit. Commission/brokerage, agency business and specified professions are excluded. Digital-receipt conditions matter for the higher turnover ceiling and the 6% component. From 1 April 2026, section 58 of the Income-tax Act, 2025 carries the corresponding business presumptive framework.

Which law applies? The return filed for AY 2026-27 still belongs to the FY 2025-26/Income-tax Act, 1961 regime. The tax year starting 1 April 2026 is governed by the Income-tax Act, 2025. This distinction matters for section numbering, forms and presumptive-tax references even where the underlying policy is substantially carried forward.

AY 2026-27 ITR business/profession code

Suggested code: 16015 — Investigation and security services.

This code comes from the official ITR-3 AY 2026-27 schema. Where more than one code is shown, choose the code that best describes the dominant actual activity. A sales channel, degree, trade name or franchise label does not override the real nature of business.

What counts as taxable receipts?

Start with the full commercial picture, not just the amount that finally reaches the bank after TDS, platform deductions, refunds or reimbursements. Typical receipts for this activity include:

guarding/security service invoices
supervision charges
event security
investigation/security assignments
equipment/monitoring service charges

Whether a reimbursement is excluded from revenue depends on the contract and whether the taxpayer is acting as a pure agent or as principal. Keep customer invoices and settlement statements so gross receipts can be reconstructed.

Which ITR should be filed?

For an individual/HUF with income from the Security Agencies activity computed under normal business/professional provisions, ITR-3 is generally the relevant AY 2026-27 return. ITR-4 is a simplified return only for eligible resident taxpayers whose business/professional income is computed under sections 44AD, 44ADA or 44AE and who satisfy the form’s other conditions, including the ₹50 lakh total-income ceiling shown on the official AY 2026-27 download page. Entity form, capital gains, foreign assets/income and other exclusions can change the return choice.

Presumptive taxation: 44AD, 44ADA or 44AE?

A presumptive scheme is a computation method, not an exemption from maintaining evidence of turnover, banking receipts, GST data or TDS credit. Before choosing it, compare eligibility, lock-out/lower-profit consequences and the interaction with books/tax audit.

Expenses under regular computation

When income is computed under normal provisions, common business costs can include the following when they are genuinely incurred for earning the receipts and are properly documented:

guard salaries/wages
PF/ESI/statutory contributions
uniform/PPE
training
site supervisors
insurance
office/admin
communication and transport

Personal expenditure, capital assets, cash payments subject to statutory restrictions, unpaid statutory liabilities and expenses lacking a business nexus need separate review. Capital assets are generally dealt with through depreciation rather than an automatic 100% deduction.

GST position

Security services can have reverse-charge implications in specified cases depending on supplier constitution and recipient. Check the current RCM notification before assuming normal forward charge.

Always reconcile income-tax turnover with GST turnover after explaining legitimate differences such as exempt supplies, exports, advances, credit notes, pure-agent items, sale of capital assets or taxes collected. A mismatch is not automatically wrong, but it should be explainable.

TDS, AIS and Form 26AS

Clients commonly withhold tax on security-service contracts. Payroll and labour-law compliance is a separate, high-risk layer and should be reconciled to the financial books.

Never report only the amount received after TDS. The payer normally deducts tax from the gross payment; the gross income is reported and the TDS is claimed separately as credit, subject to reconciliation.

Books of account and tax audit

For the tax year beginning 1 April 2026, section 62 of the Income-tax Act, 2025 deals with maintenance of books and section 63 deals with tax audit. Section 63 retains the ₹1 crore business threshold, increased to ₹10 crore where both cash receipts and cash payments stay within the statutory 5% conditions, and a ₹50 lakh profession threshold, subject to the detailed rules. Presumptive-declaration rules can create separate audit consequences. For AY 2026-27, apply the corresponding 1961-Act provisions applicable to FY 2025-26.

Worked example: Security Agencies

Assume a resident individual has ₹90 lakh security-service billing with ₹79 lakh payroll/statutory and operating costs during FY 2025-26. Under the normal method, a simplified first-pass computation is:

Particular	Amount
Gross business/professional receipts	₹90 lakh
Illustrative documented business costs	₹79 lakh
Illustrative accounting/tax profit before further tax adjustments	₹11 lakh

This is deliberately not a final tax computation. Depreciation, disallowances, personal-use apportionment, GST treatment, timing differences and presumptive-tax choices can alter taxable profit. If presumptive taxation is legally available, compare the deemed-profit route with regular books before filing rather than selecting the lower number automatically.

Documents to keep

sales/service invoices and credit notes
bank, UPI, card and payment-gateway statements
customer and vendor ledgers
Form 26AS, AIS and TDS certificates
GST returns/e-invoices/e-way bills where applicable
contracts, engagement letters or marketplace/franchise settlement statements
asset register and depreciation support
expense invoices and payment evidence
inventory/stock records where goods are involved

Common mistakes to avoid

wrong GST charge vs RCM
reporting margin instead of gross contractual receipts without basis
PF/ESI mismatches
site-wise revenue leakage
44AD use without testing turnover limits and eligibility

Check books/tax-audit requirements and advance-tax exposure.
Retain a short source file showing the law/rate/form version used for the return.

Frequently asked questions

Which ITR should a security agencies use?

ITR-3 is generally the starting return for an individual/HUF with normal business or professional income. ITR-4 is available only when the taxpayer and presumptive-income conditions are satisfied; it is not a universal small-business return.

What is the AY 2026-27 business code for security agencies?

The official ITR-3 schema contains the code(s) shown above: 16015. Where there are multiple plausible codes, choose the one matching the dominant real activity and retain a short note explaining the selection.

Can security agencies use section 44AD or 44ADA?

Does security agencies need GST registration?

Security services can have reverse-charge implications in specified cases depending on supplier constitution and recipient. Check the current RCM notification before assuming normal forward charge.

Can expenses be claimed?

Under regular computation, expenses incurred wholly and exclusively for the business/profession can generally be considered subject to specific disallowances, capital-vs-revenue rules, personal-use apportionment and evidence. Under a presumptive scheme, the deemed-income mechanism changes the deduction analysis.

What records should be kept?

Keep invoices/receipts, bank and UPI statements, customer/vendor ledgers, TDS certificates/AIS/26AS, GST returns where applicable, asset register, expense evidence and contracts. Businesses with inventory should maintain stock records suited to the activity.

What changes after 1 April 2026?

The Income-tax Act, 2025 is in force from 1 April 2026. The current presumptive framework is in section 58, specified-profession/books rules in section 62 and tax audit in section 63. AY 2026-27 itself still relates to FY 2025-26 under the 1961 Act.
