July is one of the most deadline-heavy months in the Indian compliance calendar. GST returns for June need to be filed. TDS deposited in June must be paid to the government. And for non-salary TDS deductors, Q1 of Tax Year 2026-27 closes on 31 July — meaning the quarterly TDS return is also due this month.

Missing even one of these deadlines does not just mean a penalty. It means interest charges that compound monthly, potential notices from the GST or Income Tax department, and — in the case of TDS non-deposit — the risk of expense dis-allowance in your books.

This guide gives you every key date for July 2026, explains what each filing involves, what happens if you miss it, and what to do if you are already behind.

All July 2026 Compliance Deadlines at a Glance

Check this table first. If three or more of these apply to your business, read the full explanations below.

GST Filing Deadlines — July 2026

GST compliance in July covers the June 2026 monthly cycle and, for QRMP taxpayers, the close of Q1 (April–June 2026). Here is what each filing involves.

GSTR-1: Outward Supply Return

GSTR-1 is where you report all your sales invoices for the month. Every registered supplier must file it — and it must be done before GSTR-3B, because your buyers’ input tax credit (ITC) depends on it appearing in their GSTR-2B.

Monthly filers (turnover > ₹1.5 Cr or opted for monthly): Due 11 July 2026

• QRMP quarterly filers (turnover ≤ ₹5 Cr): Due 13 July 2026 (for the full Apr–Jun 2026 quarter)

GSTR-3B: Summary Return + Tax Payment

GSTR-3B is the most important monthly GST filing. It is a self-declared summary where you report your total output tax, claim input tax credit, and pay the net GST amount. If there is no reconciliation between GSTR-1 and GSTR-3B, you risk notices and ITC mismatches for your buyers.

Monthly filers: Due 20 July 2026

• QRMP — Category 1 states: Due 22 July 2026
• QRMP — Category 2 states (Haryana, Delhi, UP, Punjab, Rajasthan, Bihar, WB, and others): Due 24 July 2026

GSTR-7 and GSTR-8: TDS & TCS Under GST

• GSTR-7 is filed by entities that deduct TDS under GST (government bodies, PSUs, and certain notified persons). Due: 10 July 2026.
• GSTR-8 is filed by e-commerce operators who collect TCS on behalf of sellers on their platform. Due: 10 July 2026.

TDS Compliance Deadlines — July 2026

Tax Deducted at Source (TDS) has two distinct obligations: the monthly deposit of tax already deducted, and the quarterly return filing that reports all deductions made during the quarter. July 2026 is particularly important because the Q1 TDS return deadline falls on 31 July.

TDS Deposit — 7 July 2026

Any TDS deducted from payments made in June 2026 — whether salary, contractor fees, rent, professional charges, or interest — must be deposited with the government by 7 July 2026.

• Who this applies to: Any business or individual/HUF whose turnover exceeded ₹1 crore (business) or ₹50 lakh (professional receipts) in the previous year, and who made TDS-applicable payments in June.
• Important note from April 2026: TDS from 1 April 2026 onwards is governed by the Income Tax Act, 2025 — not the old Act. Section references on challans for post-March payments must use the new numbering under Section 393. If your payroll or accounting software has not been updated to reflect the new Act, your TDS returns may have incorrect section references — which can trigger validation errors.

Q1 TDS Return — 31 July 2026

The quarterly TDS return covers all deductions made between April and June 2026 (Q1 of Tax Year 2026-27). It must be filed even if TDS deposits were made on time every month — the return is a separate obligation from the monthly deposit.

Key forms: 

• Form 24Q — Salary TDS (employer deducting from employee salaries)
• Form 26Q — Non-salary TDS to residents (contractors, professionals, rent, etc.)
• Form 27Q — TDS on payments to non-residents and foreign companies
• Form 27EQ — TCS (Tax Collected at Source) on various items

Deadline: 31 July 2026

TDS on Property Purchase — 30 July 2026

If your business or any individual purchased immovable property in June 2026, TDS on that transaction must be deposited by 30 July 2026. This applies to property purchases above ₹50 lakh. The challan-cum-statement is filed as Form 26QB and must be submitted within 30 days of the end of the month in which the purchase was made.

What Happens If You Miss These Deadlines

Most SME owners understand that missing deadlines causes penalties. What many do not realize is how quickly those penalties compound — and the less obvious consequences that follow.

Filing	Late Fee	Interest	Additional Risk
GSTR-1 late	₹50/day (₹20 nil return)	None directly	Buyer’s ITC blocked — your buyers may chase you
GSTR-3B late	₹50/day, capped ₹5,000	18% p.a. on unpaid tax	Repeated delays can trigger GST scrutiny
TDS deposit late	None on deposit	1.5%/month from deduction date	Expense disallowance + potential prosecution
TDS return late	₹200/day, capped at TDS amount	N/A (if deposit done)	Deductees cannot see credit in Form 26AS

Already Behind? What to Do Right Now

If you have missed a GST or TDS deadline in June or earlier, the priority is simple: file now, pay the applicable late fee and interest, and put a system in place so it does not happen again. The longer you wait, the higher the penalties — and the greater the chance of a formal notice.

For GST late filing: 

• File the pending GSTR-1 or GSTR-3B immediately on the GST portal. Calculate and pay the late fee (₹50/day, capped at ₹5,000 for GSTR-3B) and 18% interest on any unpaid tax. A reconciliation should be done to ensure the pending return does not create an ITC mismatch for your buyers.

For TDS late deposit: 

• Deposit the TDS amount immediately with the applicable interest at 1.5% per month. Then file the quarterly return (Form 24Q / 26Q / 27Q) before the deadline or as soon as possible. Note: interest must be paid before the return is filed — the portal will not allow filing with outstanding interest.

For TDS return late filing: 

• Pay the ₹200/day fee (capped at the TDS amount for the quarter) and file immediately. A penalty of ₹10,000–₹1 lakh under Section 271H applies for late filing, but this can be waived if you file within one year of the due date and pay all dues.

How to Never Miss a Compliance Deadline Again

The businesses that never face penalty notices are not the ones with the largest finance teams. They are the ones with the simplest, most consistent compliance systems. Here is what works:

1. Build a monthly compliance calendar. 

Map every GST and TDS deadline relevant to your business into a shared calendar with reminders set 7 days and 2 days before each due date. July’s deadlines — 7th, 10th, 11th, 13th, 20th, 22nd/24th, 25th, 31st — are not random. They follow a predictable pattern every month. Once the calendar is set up, it runs itself.

2. Reconcile before you file, not after. 

Every GSTR-3B should be reconciled with GSTR-1 before submission. Every TDS return should be verified against payment challans. Reconciliation is not extra work — it is the work that prevents six months of notice-handling later.

3. Separate the person who deducts TDS from the person who deposits it. 

In most SMEs, TDS defaults happen because the same person responsible for making payments is also responsible for depositing TDS — and the deposit gets deprioritised when cash is tight. A simple approval workflow, or a professional partner handling TDS, solves this completely.
