Tax Planning Timeline: What to Do Each Quarter as a Nepali Taxpayer
Most Nepali taxpayers only think about tax once a year — usually in a rush, close to a deadline, with receipts scattered and little time to plan. But Nepal's tax calendar is actually built around four clear quarters, each with its own compliance task and its own planning opportunity. Understanding this rhythm is the difference between reacting to tax season and quietly staying ahead of it.
This guide breaks the Nepali fiscal year into its four quarters — Shrawan to Ashwin, Kartik to Poush, Magh to Chaitra, and Baisakh to Ashadh — and lays out exactly what individuals, freelancers, and small business owners should be doing in each one. Whether you are salaried, self-employed, or running a registered business, this timeline gives you a practical checklist to follow all year round.
Why a Quarterly Approach Matters
Nepal's Income Tax Act requires advance tax to be paid in installments through the year rather than as one lump sum at year-end, and annual return filing has its own separate deadline. Treating tax as a once-a-year event means most people miss the smaller, quieter deadlines in between — the ones that carry real penalties if ignored. Breaking the year into quarters turns a single overwhelming task into four manageable check-ins, each tied naturally to a season of business activity.
Q1 (Shrawan – Ashwin): Registration and the First Advance Tax Installment
The first quarter of the Nepali fiscal year sets the foundation for everything that follows. If you are starting a new business, freelancing formally for the first time, or crossing an income threshold that requires PAN registration, this is the window to get registered with the Inland Revenue Department (IRD) before income starts accumulating without a formal structure behind it.
- PAN and business registration: New businesses, freelancers, and consultants should complete PAN registration early in Shrawan so invoicing and withholding are handled correctly from day one.
- First advance tax installment: Taxpayers with an estimated annual tax liability above the prescribed threshold must pay at least 40% of the estimated annual tax by the end of Poush — but Q1 is when you should already be estimating that liability so the payment isn't a scramble later.
- Bookkeeping setup: Set up (or clean up) your ledger, invoice numbering, and expense-tracking system now, while transaction volume is still manageable.
Q2 (Kartik – Poush): Annual Return Filing Deadline Focus
The second quarter carries the single most consequential deadline of the year for most taxpayers: the annual income tax return, which is due by the end of Poush for the previous fiscal year. This is also when the first advance tax installment technically falls due, so Q2 tends to be the busiest compliance quarter.
- Annual return filing: Individuals and businesses must file their annual return for the prior fiscal year by Poush-end. Late filing attracts a fee and interest, so gathering documents in Kartik rather than waiting until Poush is strongly advisable.
- Reconcile TDS credit: Match the tax deducted at source (TDS) shown on your salary certificate or vendor statements against what IRD's system reflects, so you are not overpaying or under-claiming credit.
- Advance tax installment 1: Confirm the first advance tax payment (40% of estimated liability) is settled by Poush-end alongside the return.
Q3 (Magh – Chaitra): Mid-Year Deduction Planning
By the third quarter, you have a much clearer picture of your actual income for the year, which makes this the ideal window to actively plan deductions rather than scramble for them in the last month. Decisions made now — not in Ashadh — determine how much tax relief you can legitimately claim.
- Insurance and retirement contributions: Review your life insurance premium (deductible up to the prescribed annual cap), health insurance premium, and Social Security Fund (SSF) or Citizen Investment Trust (CIT) contributions, and top these up if you have room within the deduction limits.
- Second advance tax installment: The second installment (bringing cumulative payment to 70% of estimated annual tax) is typically due by Chaitra-end.
- Business expense review: For freelancers and business owners, Q3 is a good checkpoint to review deductible expenses and ensure supporting documentation is complete before year-end.
Q4 (Baisakh – Ashadh): Year-End Closing and Next-Year Preparation
The final quarter is about closing the books cleanly and setting up next year rather than starting from zero. This is also when the third and final advance tax installment falls due, closing out the year's obligations before the new fiscal year begins.
- Final advance tax installment: The third installment (completing 100% of estimated annual tax) is due by Ashadh-end.
- Year-end closing: Reconcile income, expenses, and TDS certificates so the annual return you file in the following Q2 is accurate and ready well ahead of the deadline.
- Next-year tax plan: Use any expected salary revision, bonus, or business growth to re-estimate next year's slab exposure and plan deductions in advance rather than reactively.

Frequently Asked Question
Which quarter carries the highest compliance risk if missed?
Q2 (Kartik–Poush) is generally the highest-risk quarter, because it combines two obligations at once: the annual return filing deadline and the first advance tax installment, both falling due by Poush-end. Missing the return deadline triggers a late-filing fee plus interest on any unpaid tax, and because it lands right after two quieter quarters, it is the deadline people are most likely to underestimate. Building your document collection in Kartik, rather than waiting until the last week of Poush, is the single most effective way to de-risk this quarter.
