What to Do When
Your deferral timeline — step by step
NOW (March 2026)
Gather documents, finalize K-1 amounts, calculate your exact liability. Start saving toward your April payment. Every dollar you pay by April 15 reduces the penalty/interest base.
By April 15, 2026 — CRITICAL
File Form 4868 (federal extension) — FREE and automatic. File IL-505-I (Illinois extension) with as much payment as possible. PRIORITY: Pay Illinois first to avoid the 10% penalty cliff! Then pay as much federal as you can. Even $5,000 makes a big difference.
April – October 2026
Prepare and finalize your returns. Accumulate funds for remaining balance. Monitor IRS notices and respond promptly. This is your breathing room.
By October 15, 2026
File Form 1040 and IL-1040 (extended deadline). Apply for IRS short-term payment plan (180 days, no setup fee) or installment agreement. Apply for IL payment plan via MyTax Illinois.
October 2026 – April 2027
Make payments per your agreed schedule. Track all payment confirmation numbers. Breathe easy knowing you have a plan.
Your Deferral Options
Each strategy as a card — pick your path
Federal Extension (Form 4868)
Extends your FILING deadline to October 15 — but NOT your payment deadline. Automatic, no explanation needed, costs $0. This is step one, no matter what. You can make a partial payment when filing, and paying via IRS Direct Pay automatically files the extension for you. Not filing = 5%/month penalty up to $12,500 on $50K. Always. File. The Extension.
IRS 180-Day Short-Term Plan
Pay the full balance within 180 days, no setup fee. Best option if you can pay within ~6 months of filing. Interest: 7%/year. Penalty: 0.5%/month. Total cost on $50K for 180 days: ~$3,226. Apply online at irs.gov/opa — immediate approval for balances under $100K.
IRS Long-Term Installment Agreement
Monthly payments for up to 72 months. Setup fee: $107 (direct debit) or $178 (other). The penalty rate DROPS to 0.25%/month once agreement is active (half the normal rate). For $50K over 12 months: ~$2,832 total. Apply at irs.gov/opa. Streamlined approval for balances under $50K.
Illinois Extension (IL-505-I)
Illinois grants an automatic 6-month extension to October 15. But the PAYMENT is still due April 15! Submit IL-505-I with estimated payment via MyTax Illinois. The big gotcha: IL penalty jumps from 2% to 10% after just 30 days late. If you can only pay some, pay IL first — that penalty cliff is brutal.
Illinois Payment Plan
Up to 24 monthly payments via MyTax Illinois or Form CPP-1. Available after filing and receiving a bill. Interest and penalties continue to accrue. For balances under $15K, no financial statement required. Simple to set up online.

Recommended Hybrid Strategy
Here's the play: (1) File Form 4868 and IL-505-I by April 15 — both are free/automatic. (2) Pay as much Illinois tax as possible first (avoid that 10% cliff). (3) Pay whatever you can toward federal. (4) File returns by October 15. (5) Apply for IRS 180-day short-term plan for remaining federal balance (no setup fee). (6) Apply for IL payment plan for any remaining state balance. Estimated total cost of deferring ~$57K for ~6 months with partial upfront payment: $2,300–$4,500. That's the price of breathing room. Not ideal, but very manageable — and WAY better than the $17,000+ cost of doing nothing.
