Filing the return on time and paying what you can is always better than not filing. The failure-to-file penalty (5% per month, up to 25%) is ten times higher than the failure-to-pay penalty (0.5% per month, up to 25%). If you file on time but can’t pay, the IRS charges only the failure-to-pay penalty plus interest (currently approximately 7-8% annualized). The IRS offers formal payment plans for taxpayers who owe: short-term (up to 180 days), long-term installment agreements (up to 72 months), and in extreme cases, an Offer in Compromise (OIC) to settle for less than the full amount. Currently Not Collectible (CNC) status pauses collection activity for taxpayers who truly cannot pay, though interest and penalties continue to accrue.

✓Key takeaway

IRS payment options at a glance:

Option	Balance	Term	Setup Fee	Interest/Penalties
Pay in full	Any	Immediate	None	Stops accruing
Short-term payment plan	Under $100,000	Up to 180 days	$0	Continue to accrue
Long-term installment (online, direct debit)	Under $50,000	Up to 72 months	$31	Continue to accrue
Long-term installment (online, no direct debit)	Under $50,000	Up to 72 months	$69	Continue to accrue
Long-term installment (phone/mail/in-person)	Under $50,000	Up to 72 months	$225 ($107 low-income)	Continue to accrue
Installment (over $50,000)	$50,001-$250,000	Up to 72 months	$225	Continue; requires financial disclosure (Form 433-A/B)
Offer in Compromise	Any	Lump sum or periodic	$205 (waived if low-income)	Stops on accepted balance
Currently Not Collectible	Any	Indefinite	None	Continue to accrue
Partial Pay Installment Agreement	Any	Based on ability to pay	$225	Continue; reviewed every 2 years

Penalty and interest rates (2025):

Type	Rate	How Applied
Failure to file	5%/month (max 25%)	On unpaid tax, stops after 5 months
Failure to pay	0.5%/month (max 25%)	On unpaid tax, reduced to 0.25%/month during installment agreement
Interest	~7-8% annually (federal short-term rate + 3%)	Compounded daily on unpaid tax + penalties
Estimated tax penalty (IRC 6654)	Same as interest rate	On quarterly underpayment amounts

The 10-year collection statute (IRC 6502): The IRS has 10 years from the date of assessment to collect a tax debt. After 10 years, the debt expires. Filing an OIC or requesting certain collection alternatives can extend or toll the statute. The collection statute is important for large debts: if the taxpayer can’t pay in full within 10 years, the IRS may accept a partial payment installment agreement where the monthly payment is based on ability to pay, and the remaining balance expires when the statute runs.

Offer in Compromise (OIC) acceptance rate: The IRS accepted approximately 33% of OIC applications in recent years. The OIC requires the taxpayer to demonstrate that they cannot pay the full amount through any combination of assets and future income. The IRS calculates a “reasonable collection potential” (RCP) based on assets (at quick-sale value) plus future monthly income (multiplied by the remaining collection period). If the offered amount exceeds the RCP, the OIC may be accepted.

What if you owe taxes you can’t pay?

Hypothetical example

Round numbers. For current guidance, see IRS installment agreement guidance. A plumbing contractor. Sole proprietor. Owes $25,000 from last year’s return. Can’t pay in full.

Option 1: Short-term payment plan (up to 180 days) Available if total balance (including penalties and interest) is under $100,000.

Feature	Details
Monthly payment	$25,000 / 6 months = $4,167
Setup fee	$0
Interest accruing	$25,000 x 7% x 6/12 = $875
Penalty accruing	$25,000 x 0.5% x 6 months = $750
Total cost of delay	$1,625
Total paid	$26,625

Apply online at IRS.gov (immediate approval for balances under $100,000).

Option 2: Long-term installment agreement (up to 72 months)

Feature	Details
Monthly payment	$25,000 / 36 months = $694 (or up to 72 months = $347)
Setup fee	$31 (direct debit, online setup)
Interest over 36 months	approximately $2,800
Penalty over 36 months	approximately $2,700 (reduced to 0.25%/month during agreement)
Total cost of delay	$5,500
Total paid	$30,531

The installment agreement is essentially a loan from the IRS at approximately 7.25% interest (interest + reduced penalty rate). This is competitive with many business loans but requires filing all returns on time and making all payments on time for the duration.

Option 3: Offer in Compromise The plumber’s financial situation:

Item	Amount
Bank accounts	$3,000
Vehicle equity (FMV minus loan)	$5,000
Equipment equity	$8,000
Monthly income	$6,000
Monthly necessary living expenses	$5,200
Monthly disposable income	$800
Remaining collection period	96 months (10 years minus time elapsed)

RCP calculation (lump sum offer): Assets (quick-sale value, 80% of FMV): ($3,000 + $5,000 + $8,000) x 80% = $12,800 Future income: $800/month x 12 months (lump sum uses 12 months) = $9,600 RCP: $12,800 + $9,600 = $22,400

Minimum lump sum offer: $22,400 (paid within 5 months of acceptance)

The OIC doesn’t save much in this case ($25,000 debt vs. $22,400 offer). OIC makes sense when:

The debt is much larger than the RCP (e.g., $100,000+ debt with $30,000 RCP)
The taxpayer has minimal assets and limited income
The collection statute is running (remaining years are few)

Option 4: Currently Not Collectible (CNC) If the plumber’s monthly expenses equal or exceed monthly income (no disposable income), the IRS may place the account in CNC status.

Feature	Details
Monthly payment	$0
Collection activity	Suspended (no levies, no garnishment)
Interest and penalties	Continue to accrue
Federal tax lien	May still be filed (public record, affects credit)
Review period	IRS reviews annually (if income increases, payments resume)
10-year statute	Continues to run (debt may expire)

CNC is appropriate when the taxpayer genuinely cannot pay anything. It’s not a settlement; the debt remains and grows. But if the 10-year statute expires before the taxpayer’s financial situation improves, the debt disappears.

Comparison of all options:

Option	Total Paid	Time	Credit Impact
Pay in full	$25,000	Now	None
Short-term (6 months)	$26,625	6 months	None (no lien filed under $25K)
Installment (36 months)	$30,531	36 months	Possible lien if over $25K
OIC (lump sum)	$22,400	5 months after acceptance (12-24 month process)	Lien filed during process
CNC	$0 now (debt grows)	Indefinite	Lien likely filed

Business owner specific considerations:

Estimated taxes going forward. The IRS requires all current-year estimated taxes to be paid on time during an installment agreement. A missed estimated payment can default the agreement.
All returns must be filed. The IRS will not approve a payment plan if there are unfiled returns. File all missing returns first (even if you can’t pay).
S-Corp payroll taxes are different. Trust fund taxes (the employee’s share of FICA and withheld income tax) have personal liability for the “responsible person” under IRC 6672. These taxes are not dischargeable in bankruptcy and have aggressive collection. ALWAYS pay trust fund taxes first.
The penalty abatement request. First-time penalty abatement (FTA) waives the failure-to-file and failure-to-pay penalties for one tax period if the taxpayer has a clean 3-year compliance history. On a $25,000 balance, FTA could waive $3,000-$5,000 in penalties.
State tax debt. State tax agencies have their own payment plans with different rules. State collection can be more aggressive than IRS collection (faster liens, bank levies).

What options are available if I can’t pay my tax bill in full?

The IRS offers several payment alternatives. An installment agreement (Form 9465) lets you pay over time, with guaranteed approval for balances under $10,000 if you can pay within 3 years, and streamlined approval for balances under $50,000 payable within 72 months. An Offer in Compromise (Form 656) settles the debt for less than owed, but the IRS accepts only about one-third of applications because you must prove you can’t pay the full amount through income or assets. Currently Not Collectible (CNC) status suspends collection when you demonstrate that paying would create financial hardship, though interest and penalties continue accruing. Penalty abatement (first-time or reasonable cause) can reduce the amount owed by removing failure-to-file and failure-to-pay penalties, which often constitute 25-47% of the balance. Interest is charged on all unpaid balances and generally cannot be abated, which makes resolving tax debt sooner always less expensive.

What is an offer in compromise and who qualifies?

An offer in compromise (OIC) lets you settle your tax debt for less than the full amount owed. The IRS evaluates your ability to pay based on income, expenses, asset equity, and future earning potential. You qualify only if full payment through an installment agreement or other means is not feasible. The IRS uses a formula: monthly disposable income multiplied by the remaining collection period (typically 12 or 24 months) plus equity in assets equals the minimum acceptable offer. The application fee is $205 (waived for low-income applicants), and you must be current on all filing obligations. The acceptance rate is roughly 30-40%, and the process typically takes 7-12 months.

What is currently not collectible status and how do you qualify?

Currently not collectible (CNC) status is an IRS designation that temporarily suspends collection activity when you demonstrate that paying the tax debt would create an economic hardship. To qualify, you submit Form 433-A (Collection Information Statement) showing that your monthly income minus allowable living expenses leaves nothing available for payment. The IRS uses its own allowable expense standards (national, local, and other necessary expenses) rather than your actual spending, so expenses like private school tuition or luxury costs won’t count. CNC status doesn’t eliminate the debt or stop interest and penalties from accruing, but it does prevent levies and liens (though existing liens remain), and the 10-year collection statute under IRC 6502 continues to run, meaning the debt may eventually expire.
