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 cannot pay?

Hypothetical example

Round numbers. 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).
